The Blood Refining Technique involves too many unknown secrets, and Chen Hai dared not spread it outside. Through his divine thoughts, he would tell Cang Yi to know about the battle with Kuntai.

Cang Yi nodded, and Kuntai also knew that the fact that he had secretly practiced the blood and refining technique could not be spread. Therefore, except for Kuntai himself, the tribe he was in did not have the most evil method such as Wu Man practiced, so there was no need to worry about the fact that the blood demon catastrophe would be completely out of order.

The remnants of Tuoba's tribe have retreated into Bailu Gorge. They dare not come in easily before finding out the situation. To the south of Yuzhu Peak, the Yuantiao Gorge is also in chaos. It will take some time for Tie Kun to gather some of the available remnants and build a defense line on the northern slope of Yuzhu Peak. Chen Hai is not in a hurry to take the next action.

Although he and Kuntai fought for a short time, they also consumed their true energy. Seeing that Cang Yi was presided over the central formation here, he was also exhausted, so he and Cang Yi and others stood cross-legged in the hall, and the hall calmed down, but from time to time, one or two roars of vagueness, tragic or despair were heard.

At this time, Tuoba Qi drove his cavalry into Bailu Gorge, and to the east of Bailu Gorge, the ground was filled with corpses destroyed by thunder, and their grave sockets were all broken.

Previously, to the east of Bailu Gorge, there was a lonely peak that was more than a thousand feet high, standing side by side with the Yuzhu Peak in the south. During several major earthquakes at the beginning of the year, this lonely peak collapsed, revealing the ancient underground palace, which was also the reason for this battle.

The Mengwu tribe recruited tens of thousands of slaves and cleared the gravel that collapsed from the lonely peak into the deep valley in the south step by step. A basin of six or seven miles was cleared between Yuzhu Peak and Bailu Gorge. Who would have thought that this would be the burial site of nearly 20,000 soldiers in Tuoba Banner?

During the years of the process of beating the border, he had also seen the power of the human formation several times, but he did not expect that he would suffer such a huge loss here.

With a violent gasp, Tuoba Yan rushed to Tuoba Qi in a mess. At this time, he was no longer as calm as before. He was dressed in a black witch robe and had several charred spots on his body. When he ran for his life, he was also hit by several thunder pillars. Fortunately, he had a deep cultivation level and escaped from the coverage of the thunder in time to save his life.

The thunder no longer struck down, and the thick clouds in the sky rolled and dissipated.

Although the Tuoba tribe has 100,000 elite combat soldiers west of Bailu Gorge and Bailu Gorge, and 30,000 elite combat soldiers south of the Demon Ape City. Although it cannot be said that it is broken, nearly 20,000 elite combat soldiers were destroyed at one time. Is this extremely terrifying blow to morale?

Before we figure out what happened in front of us, how can we fight this battle?

This is the Thunder Array that has caused heavy damage to the Black Stone Khan Mu Hao?

Tuoba Qi now confirms that Mu Hao, a hero of the Hanhai generation, has indeed suffered heavy damage and has not been healed, but it is not that Mu Hao broke into the underground palace to trigger a large formation. Why did they fight on the underground palace and the violent thunder waterfall suddenly form?

Could it be that someone from the Mengwu tribe saw that Bailu City was invaded and broke into the underground palace desperately to trigger a large formation?

Tuoba Qi and others recovered from their shock. No matter what, the Mengwu tribe had been completely defeated. Everything they had just encountered made them even more determined to take this formation into their hands.

Teams of barbarian soldiers shrank timidly and did not dare to move forward, as if he was hell ahead.

Looking at the war heroes with a little depressed morale, Tuoba Qi shook his head helplessly. In fact, he could order the slaves to do these things, but this knot in his heart would not be eliminated. How should we fight the next war?

Finally, under the cover of yellow and yellow groups, the barbarian soldiers who were wielding the thunder-controlling technique by Wu Man stepped onto the edge of the Tiangang Thunder Prison Formation. A barbarian soldier carefully raised his feet, gently stepped onto the charred ground, and then quickly raised it. It seemed that if there was any abnormality, he would immediately turn around and run away.

There was still only the sound of wind roaring between heaven and earth, and there was no situation of ten thousand thunder again. It was just that his neurotic behavior caused other monsters to riot and almost turned around and fled.

The finishing work continued until midnight. Tuoba Qi stood at the head of Bailu City like a sculpture until the last team of soldiers retreated into Bailu Gorge that he went down to rest.

The fatigue of fighting for several days made him fall asleep quickly. In his dream, he successfully opened the ancient underground palace, obtained countless ancient treasures such as the formation, and even many true secrets of the mysterious method. From then on, the Tuoba tribe opened the inheritance of the Hanhai Grassland for generations...

************************************

The weather was a little gloomy the next day, and the howling north wind circled in the valley. While the Tuoba army did not dare to move westward from Bailu Gorge, Tie Kun led the Tieya army to build a simple line of defense while the west slope of Yuzhu Peak was at night to block the passage into Yuantiao Gorge.

The defense line was very simple, just made of soil and rocks, watered into ice to reinforce it. However, after a night of chaos, more soldiers, combat equipment and armor from the Tieya Division were transferred over.

Over the past month, Zuo Jiu led 30,000 troops to block the Tieya tribe in the Yuantiao Gorge, digging trenches outside the Demon Ape City, building camps, and sending more posters and scouts outside the Demon Ape City. In fact, Zuo Jiu and Tuoba Qi are not very clear about the matters inside the Demon Ape City and the Ape City.

The Tieya tribe was deployed on the west slope of Yuzhu Peak at this time, and the level of equipment was really surprised by Tuoba Qi.

Whether it is a gold quenching iron shield that is several inches thick and two meters high, or a gold quenching spear that shines with sharp light, even the Tuoba tribe does not have many. The Tieya tribe can take out thousands of equipment soldiers and horses at one time and deploy them on the north slope of Yuzhu Peak?

Guo Hong and Qi Hanjiang and the others came here this time and brought thousands of gold-quenching equipment into Yaoshan to strengthen the soldiers and horses of the Tieya tribe. At this time, they were all deployed to the west slope of Yuzhu Peak, but only this was limited to this. The south side of Yaoshan was the scammers of the Tuoba tribe. Unless they directly sent elite troops to escort, it would be difficult to transport the weapons secretly into them.

Tuoba Qi stood in a stone ridge on the south side of Bailu Gorge, looking at the west slope of Yuzhu Peak opposite, his face turned gloomy.

At this time, Tuoba Yan led several great witches from the tribe to come over, looking haggard, and said to Tuoba Qi with a voice: "We have set up a detection array to monitor the movements of the heaven and earth's essence within a radius of 300 miles. At this time, Lei Yuan Gangsha is constantly rushing into the underground, but based on the power of yesterday's Lei Waterfall, with the gathering speed of Lei Ye Gangyuan at this time, it is estimated that this array will take one month to use the Lei Ye Gangsha waterfall like yesterday."

Many barbarians were eager to try, and with a month's buffer time, they had already taken down the Yuantiao Gorge.

Tuoba Qi shook his head and said, "There are too many accidents. We need to consider that the possibility of Wu Man entering the underground palace in the Tieya tribe and mastering the central formation. At this time, the speed of the underground palace formation gathering the Thunder Evil Gangyuan is very slow, but it may not be a strategy to lure the enemy. If our troops' offensive is launched in front of Yuzhu Peak and are suddenly attacked by thunder, how can we fight this battle?"

Tuoba Yan was still in shock at this time. Knowing that someone was hosting the underground palace formation and no one was hosting it, they were completely different, so he asked: "Then let's go back to the south and attack the Demon Ape City?"

To understand the real situation of the ancient underground palace, they could only divide their troops to garrison Bailu City to the west. However, the best way to transfer the main force to the south of Yuantiao Gorge and attack the Demon Ape City is, but just adjusting the strategy directly in this way is too harmful to morale.

Besides, even if the Wu Man from the Tieya tribe has entered the underground palace to control the central formation, as long as the vital energy of the heaven and earth around does not change drastically, within at least two or three days, the Wu Man from the Tieya tribe will still be unable to control the underground palace formation to use the Thunder Waterfall that destroys the world.

Thinking of this, Tuoba Qi decided to send thousands of troops to attack the simple defense line deployed by the Tieya Division on the west slope of Yuzhu Peak to explore the virtual and the real.

The sound of trumpets sounded, and the vanguard battle formations accumulated by the Tuoba tribe in Bailu Gorge, splitting thousands of troops into the underground valley.

Two thousand barbarians charged towards Yuzhu Peak from the left and right wings. The strong barbarians took advantage of the force of the combat cavalry to charge and threw short spears made of fine iron into the position of the Iron Cliff, as if a black thunder net was covered.

In the battle formation of the Tieya tribe, he heard clanging sounds all the time. All the soldiers in the front row squatted down and raised the heavy and strong gold-tempered shield and linked them together. A giant turtle wall had already formed. A powerful and heavy spear was stabbed hard, and sparks were splashing everywhere, and they tried several times, but they could not shoot through the shield wall.

The barbarian cavalry, who had already rushed to the foot of Yuzhu Peak, naturally was unwilling to retreat. They wandered on both wings and soon divided more than 200 cavalry, urging the battle beasts under their crotch, increasing their speed from far to near, and then moved to the earth wall. They pulled the reins hard, and the ferocious battle beasts soared into the air, jumped over a three or four-meter-high obstacle in the sky, and rushed to the front of the Iron Cliff formation.

Each of the war beasts under the crotch of the Manqi was extremely majestic, weighing two or three thousand pounds, as fast as a galloping horse. However, although it could easily jump over the earth wall, it could not break the interlocking shield wall. It was blocked from the shield wall and was not firmly established. Then a sharp spear was seen from the gap between the shield wall, like a poisonous snake stabbing out of the hole.

The space for circling between the shield wall and the guard wall is limited. These more than 200 elite cavalry rushed over but had no room to move. They couldn't even retreat in panic and were forced to leave more than a hundred corpses before they could get a distance and gather with the cavalry on the left wing...

The defense formation of the Tieya Division was extremely tough, and the gorge on the west slope of Yuzhu Peak was too narrow, which was not conducive to the cavalry's rushing forward. At this time, the three thousand barbarian armors carried more than a dozen simple stone-dumping crossbows and surrounded the Yuzhu Peak.

No matter how strong the shield wall is, it can only withstand hundreds of pounds of stone bullets and throw them from two thousand steps away.

The wind gradually became stronger, and snowflakes were already falling in the sky. Tuoba Qi squinted his eyes, looking forward to the bloody scene. But at this time, he saw the elite soldiers of the Tieya tribe starting to close to the back, Tuoba Qi's heart was abrupt. His first thought was that Wu Man from the Tieya tribe would launch the underground palace formation again?

Tuoba Qi turned his head and looked at Tuoba Yan. Tuoba Yan shook his head, indicating that there was no violent fluctuation in the vitality of heaven and earth.

At this time, a thousand-person armored barbarian in Tuoba's army had approached the earth wall. Without anyone to harassing them, they completely pushed the earth wall as if they were venting their anger. Behind them, the stone-throwing crossbow also set up, and the slave soldiers transported the stone bullets up...

Tuoba Qi actually wanted to force the soldiers of the Tieya tribe to give up the shield wall and come out to compete with them for the position of throwing stone crossbows, otherwise they would compete to seize the Yuzhu Peak and advance into the Yuanjue Gorge.

At this time, the sound of hooves in the distance was like thunder, as if thousands of warriors were running wildly among the mountains.

Tuoba Qi's face was as heavy as water, and there would be no thousands of wolf riders rushing over to the Iron Cliff. The monkey gorge south of Yuzhu Peak was extremely narrow and did not allow thousands of war riders to attack. Moreover, the sound of iron hooves trampling on the ground was much duller than that of ordinary riders. Although the aura was chaotic, they were all extremely powerful. They were much stronger than ordinary war riders...

Unexpectedly, the Tieya tribe had such a backpack, but Tuoba Qi would not have hastily ordered the withdrawal of troops. In fact, in such a short time, the five thousand backpacks that had entered the underground palace valley did not have enough time to retreat into Bailu Gorge. He could only look at everything in front of the mountain in cold blood.

The vanguard general was also shocked, but he did not receive the order to withdraw the troops. He could only grit his teeth and shout loudly, ordering the three thousand barbarian armor to shrink to the position where the stone crossbow was throwing, and arrange the iron shield and spear on the periphery to prevent the next impact; the two thousand war cavalry were arranged on both wings, lifting the battle halberd, and unshelf, preparing to pinch the enemy's rushing formation from both wings.

At this time, a giant demon mastiff that was unimaginable came from the south slope of Yuzhu Peak; behind it were more than thirty giant monsters, revealing their hideous claws and rushing out of Yuzhu Peak.

Not to mention the five thousand soldiers who had not had time to retreat into Bailu Gorge, Tuoba Qi, Zuo Yang, Tuoba Yan and others standing on the Shiling opposite Yuzhu Peak were all frightened at this moment, moaning in pain. They never thought that the unknown Tieya tribe would have such a monster warrior to help.

Especially the giant demon in the head of the demon mastiff, which exuded a destructive aura, with snow-white fangs spread out, and angry blue flames hidden in the demon's eyes. The hideous head was raised high, eleven or two meters from head to toe, and covered with black scales, like a black stone cliff, and was about to smash towards the foot of the mountain.

There have been thousands of years since the Hanhai Grassland, let alone such a huge and terrifying demon mastiff monster.

How many years have such a huge demon mastiff and monster practiced in the depths of the vast sea grassland?

In addition to this demon mastiff, more than 30 other monsters have different shapes, including black scales, green scale giant wolf, black horned demon tiger, and ice field giant ape. Regardless of their cultivation, they can tell that in the depths of the Qianhai Grassland, they have at least three or five hundred or even thousands of years of climate, and their body size is at least five or six meters high.

There were not enough powerful generals to take the battle and the five thousand barbarians who had no time to retreat into Bailu Gorge would definitely not be able to withstand the bloody trampling of these thirty monsters - even if these monsters had not comprehended the powerful magic and magic, such a terrifying body shape and incomprehensible scales and bones that were incomprehensible to the gun were already a crushing advantage.

When Tuoba He was about to lead a team of elite black armored soldiers and rushed into the underground valley in person, he heard the demon mastiff standing at the foot of Yuzhu Peak Mountain and roaring. The cloudless sky slashed down dozens of thunder pillars out of thin air and blasted towards the stone ridge here. Then another powerful and bloody spiritual sense appeared out of thin air in the minds of Tuoba Qi and others:
Chapter completed!
