The reason why the enemy was discovered by Gu Erdan when he was digging the tunnel was actually very simple.

That is, Gu Erdan has a special combat team that is good at detecting underground situations.

Have you heard of the fourth-level skeleton rat?

Not to mention hearing about ordinary undead spirits, I am afraid I have never seen a second-level skeleton rat in my life.

After all, who can train skeleton rats by brains?

Facts have proved that skeleton rats really have no value to cultivate. Even if they are promoted to level 4, their combat power is still pitifully weak.

However, their excavation speed has been qualitatively improved, and the most important thing is that their perception ability of the underground has also become extremely terrifying.

As long as there is abnormal underground movement within a radius of ten miles, they can accurately detect it, which can be called an underground radar.

It was also because of the skeleton rat that Gu Erdan could detect the other party's small movements and thus wait for the rabbit.

In the early morning of the second day, with the black sun rising again, the fourth round of the enemy's attack began.

But this time they did not rush over without thinking, but began to arrange troops like a war between the two armies, and all the troops were approaching.

Standing in front of the enemy army was a cavalry, a domineering cavalry with a number of up to 300 and a domineering cavalry with black aura all over them.

Death Knight! The peak of the undead intermediate troops! Born to have level 5 strength! At this time, there are as many as 300! It is definitely a force that cannot be underestimated!

And at the forefront of these Death Knights, there is an even more domineering presence!

King of Death Knight! Seventh-level boss! One of the three kings of the Underworld Palace! The direct subordinate of the King of Underworld!

He once relied on the joint charge of the Death Knights under his command to kill three of his same-level existences in one battle! It is even rumored that he led his Knights under his command could compete with the eighth-level existences!

In fact, the Death Knight Alay didn't care about it.

But he cares about time!

According to the original plan, he should preserve his strength and disguise his identity, rely on the recruited cannon fodders to forcibly cross the defense line, and then lead the elite troops to attack the opponent off guard.

For this reason, he even spent several days bringing these slow-moving cannon fodder over.

But who would have thought that the other party had put a hard bone here as if he knew his plan.

The original plan has failed. Even if he can try his best to break through the opponent's defense line, this level of hard bone will inevitably cause the opponent's vigilance.

Although the 300 Death Knight is strong, it is not invincible. If you fall into the sea of ​​people and lose your mobility, you will eventually be submerged by the sea of ​​people.

After straightening his helmet, Death Knight Aray showed a decisive look in his eyes.

Now that things have come to this point, I can only choose to break through forcibly at any cost.

Relying on the Death Knights' perfect mobility and assault power, as long as they can break through the defense line before the target behind reacts and successfully rush to his target, there will be still some battles.

Without any nonsense, the Death Knight Arey buckled the cover under the cover and suddenly pulled the reins.

The fourth-level undead horse under the cross neighed and launched a fearless charge towards the endless undead in front of him! At the same time, it activated all its abilities!

Howling speeds up!

Charge of death!

Netherworld Phantom!

One after another, light flashed on the Death Knight! The 300 Death Knights carried the monstrous aura and opened their war.

The Death Knight Alay, who was rushing in front, suddenly swung the flat rifle in his hand! A black haze spread from him, turning into a shackle and passing it to other Death Knights.

Seven-ringed Necromancer spell! Death Shackle!

At this moment! The 300 knights seemed to be integrated! The momentum was crazily increasing!

Near! closer!

I only saw the sky suddenly dark! The overwhelming arrows mixed with javelins fell like raindrops!

These attacks fell on the Death Knights, hitting the smog that enveloped them until it kept rippling!

The combined attacks of hundreds of fourth-level undead spirits are actually difficult to break through the opponent's magic barrier!

Gu Erdan was suddenly shocked when he saw this scene. The black warrior army next to him reacted faster and directly set up a shield to form a simple shield wall to protect Gu Erdan.

At this time, not only Gu Erdan was shocked, but also Death Knight Yare was also surprised.

He knew that these enemies were very strong, but he never expected that they would be so strong!

This wave of intensive offensives is enough to kill the fifth-level undead! None of the arrows or javelins fell from mid-air, the power is weaker than the fourth-level.

If it weren't for the Seven-ringed Spell Death Shackle that could gather all the power of the connected person to prevent this round of offensive.

The Death Knight charges by himself alone, I am afraid that more than 30% of the combat power will be reduced by this round of offensive!

The cavalry charge was astonishingly fast, especially the large-scale charge initiated by a group of 100 people.

With full speed, not to mention that the attack ahead can withstand, even if they can't withstand it! There is only one choice to rush to the end!

There is no turning back when you open the bow! Either break the formation and pass by! Or break the arrow here!

With a loud bang! 300 death knights with momentum connected in one circle, facing arrows all over the sky! Hit hard on the shield wall composed of advanced skeleton guards!

The heavy bone tower shield, which is more than half a person tall, failed to stop the opponent's sprint, and did not even slow down the opponent's speed!

The skeletons were shattered! Groups of skeletons were washed away!

The first layer of heavy armored defense line! Break!

The united black gas cuts three levels! The Death Knight Aray roars! Lead the soldiers to continue rushing forward!

What comes to us is the second layer of defense! It is also the line of defense that poses the greatest threat to the Death Knight! The gun forest formation consists of skeleton spearmen, skeleton spearmen, axe soldiers, and skeleton spearmen!

These guys were originally responsible for hiding behind the skeleton guards and using their weapons to attack the enemy.

At this time, the shield wall was broken, and the guys pressed tightly together, stabbing the spear in their hands with all their strength!

The spearmen and cavalry are fighting! The two are mortal enemies! Life and death are unpredictable when fighting!

But today the combat power of both sides is not equal! Relying on the blessing of the Seventh Ring Spell, the Death Knights' momentum is like a rainbow! They actually hit the gun forest without hesitation!

Countless spears broke! Countless skeletons collapsed!

The Death Knights who rushed through the formation in awl-shaped shape! They rushed through the second round of defense again without any injuries!

However, the black gas that united them had dropped to only about 40% of them at this time! Even the rich black fog began to gradually fade and distort!

Third floor! Long-range troops!

The skeleton thrower directly picked up the hammer in his hand, and the slingshots put away their toys without hesitation and showed the battle axe in his hand!

Even those skeleton archers who are not good at melee combat dropped their longbow without hesitation! They took out a bone pocket version of the fruit knife...

The defense line in the third round was not unexpectedly broken through, even if the Death Knights broke through two consecutive formations, it was already at the end of their strength.

It is easy for them to break the formation against a group of guys who are not good at defense.

Seeing that all three elite enemy troops were captured by him, Death Knight Aray secretly breathed a sigh of relief.

After a surprise attack by the Air Force, he had already discovered that the first three enemy troops were very powerful this time.

Even the troops responsible for long-distance attacks had extraordinary combat effectiveness.

But that's all! Go past these three elite troops! The skeleton soldiers with messy formations in the rear were just brought by this guy to support the venue! It can be broken in the blink of an eye!

As long as you break out of the enemy's encirclement, then this plan will not be a failure! No matter how big the sacrifice is, it is worth it!

Pulling the reins! Death Knight Alay took the lead in rushing towards the messy skeleton reserve team of the camp, completely ignoring Gu Erdan, who was tightly protected by the Black Warrior Legion.

Looking at the death knight Alay who led the cavalry to whizz the black warrior and plunged into the reserve team, Gu Erdan showed a confused expression on her face.

Isn't this guy rushing over here so hard, isn't he going to implement the beheading plan?

Is he here? Hey! Why is he running towards the reserve team?

More than 6,000 reserve members who were gathering together in the back, all of whom took out their various weapons with excitement as they watched the cavalry approach him.

Oh! The big fish is here!

Could it be that we will finally make a breakthrough in the army?!
Chapter completed!
