Although Du Yu cooperated with him, the core of this cooperation has always been Du Yu!

Aragon has a high opinion of himself. With the noble bloodline of Isido's descendants, he is definitely not a short-seller who is a puppet!

Du Yu rejected Aragon's proposal several times and acted arbitrarily, which had violated Aragon's bad luck. The pinnacle,

But this sprinter king who had been running for half his life had already learned to endure for a while and keep a low profile in the cruel years. Before he gained absolute power, he had to rely on Du Yu, his ally to kill Sima Yi for him.

But when he saw Du Yu teasing Wuji with Kellandriel in the gauze of the carriage, a trace of sinister murderous intent flashed in his melancholy eyes.

Du Yu and his group continued to move forward. After 10 days of Mercedes-Benz, they finally saw the destination of the trip!

Holy Helmet Valley!

Entering the valley from the shadow of the north side of Mount Shiliheng, there is a huge rock at the entrance of the deep valley. The pass has high ancient stone walls, made of pure large stones, without even a gap for climbing. There is a high tower inside, which is more than 100 meters high, overlooking the entire fortress!

This is the most solid fortress in Luohan Kingdom, and its destiny is bound to the fortress, Holy Helmet Valley!

Under the Holy Helmet Valley, a complex and huge shelter was built, which could store a large number of people for them to avoid natural disasters and powerful enemies. They would wait until the enemy was killed and retreated before returning to their homes.

The Holy Helmet Valley has saved Rohan's fate more than once, and has made this country that lasted for more than 500 years and has a long history.

Now, Regent Du Yu, with a large number of people and knights, came to this Holy Helmet Valley again.

Although 200,000 people who fled, after Iowin's patient work and persuasion, as many as 150,000 were diverted to the Golden Forest of Kelantriel as refugees. But Du Yu also selected 50,000 strong people. As a reserve team, he followed the army to the Holy Helmet Valley.

Yi Owen and Shen Luoyan had already come here one step ahead. They were responsible for the transportation of refugees and food and grass respectively.

Shen Luoyan came immediately and reported to Du Yu: "The army has not moved, and the food and grass will go first. I have worked hard to mobilize food and grass from all over Luohan. But as of this time, I have only hoarded about 400 vehicles. If 20,000 soldiers are enough for 6 months to eat, but you have also brought 50,000 refugees. The consumption rate of food and grass will be much higher than expected. We can last for up to 3 months."

Du Yu nodded: "We wiped out Sima Yi's cavalry on the way. This guy probably feels a strong sense of crisis. I am sure he will quickly bring the subsequent heavy infantry to siege the Holy Helmet Valley. But the task of mobilizing food and grass cannot be stopped. We must speed up."

Iowen came up to report: "The refugees have been properly placed. In the Io era, terrain caves were used to build a little underground cave, which could just accommodate 50,000 refugees and 20,000 troops. I have already recruited refugees in their prime and began to increase the disrepaired city walls and towers in accordance with the suggestions of General Shen Luoyan.

Du Yu looked up.

From the terrain, this Holy Helmet Valley is worthy of being a fortress that never falls.

The sides of Mount Shiliheng spread. The deep valley suddenly narrowed, and the ancestors of the Lohan people built a city wall of 20 meters high here. There were towers everywhere, arrow towers and shooting ports to cover each other, which was indeed a terrain that could not be opened by one man.

However, after years of disrepair, the Holy Helmet Valley was indeed dilapidated. Large areas of green vines grew on the city walls and large stripped surfaces of the city walls also damaged the solidity of the defense. Especially the water outlet to prevent mountain torrents became the focus of Saruman's breakthrough in the plot.

"Sima Yi is unstoppable. We will definitely not gain a firm foothold in the near future and launch a fierce attack." Du Yu said in a deep voice: "It's better to follow Luo Yan's instructions. By the way, there is Wang Yuyan who has learned the mechanism, and you two will give us guidance. Accelerate the construction of the Holy Helmet Valley."

Wang Yuyan appeared in front of Du Yu in a delicate manner and whispered: "Cousin, I think this Holy Helmet Valley may not be able to block Sima Yi's army."

Du Yurao was interested and picked up his cousin and immediately said intimately: "Cousin is amazing?"

Wang Yuyan was intimate by her cousin in front of everyone, and she was so embarrassed that she buried her head in Du Yu's arms and struggled to get off.

Du Yu laughed and dismounted, took Kelantriel and others to patrol the city walls.

Wang Yuyan whispered: "I have calculated the defense of the Holy Helmet Valley. Its maximum shooting volume is limited by the narrow fortress shooting position, which is 130 arrows per second!"

Du Yu felt nervous when he heard this.

Legolas nodded in praise: "Yes, this Helmet Valley Fortress is indeed easy to defend and difficult to attack, but the problem is also here. It is too narrow and the length and width of the city wall are not enough. We have 10,000 elves, and 500 elves shooters standing on the city wall are already full. The shooting positions on the tower are also narrow and cramped, not enough to maximize the advantages of elves archery."

Shen Luoyan nodded in praise and said, "This is because the wars in Middle-earth are not large in scale. For example, in ancient times, the alliance battle between humans, elves and dwarves against Morgoth, it was a god-killing and a race war. The total force mobilized by both sides was no more than 50,000. And the total scale of our battle with Sima Yi this time has exceeded 40,000! The Holy Helmet Valley has reached its limit to deal with the battle of about 10,000 people. And this scale of battle far exceeds its original design intention."

Du Yu sighed and nodded.

The Holy Helmet Valley is indeed sufficient to use as a refuge for the country of Rohan. Usually, the enemies of the Lohan Kingdom, the brutal and hungry orcs in winter, surge from the misty mountains. When the Lohan Knights were not enough to deal with it, they were enough to hide in the Holy Helmet Valley.

But this time the enemy was crazy and Sima Yi, who was willing to turn the people into ghost soldiers!

How can the army led by this kind of jackal with no moral integrity and no limit be comparable to that of the winter orcs?

The information Du Yu received was Sima Yi's heavy infantry, with more than 25,000 people.

But that is the intelligence of love.

Will Sima Yi be crazy and sturdy after his defeat in this battle, and transform Gondor's extremely rich human resources into endless ghost soldiers?

This kind of thing is natural.

Under the overload attack, the Helmet Valley is too narrow, and the weaknesses of insufficient defense width and depth are fully exposed.

Du Yu even regretted it a little. He had known that a decisive battle with Sima Yi's heavy infantry on the grassland could maximize the advantages of the Knight Luo Han. Why did he travel thousands of miles to venture to the Holy Helmet Valley?

But the opponent is Sima Yi, and you cannot feel contemptuous just because you defeat him once.

Du Yu reminded himself.

The terrain of Holy Helmet Valley is the safest defensive plan no matter where you think about it.

Du Yu coldly swept to Shiliheng Mountain.

The Holy Helmet Valley is located in the depths of Mount Shryheng.

"Can you build a larger city wall outside the Holy Helmet Valley? Expand the defense line of the Holy Helmet Valley? Increase the width and depth?" Du Yu had a sudden idea.

Everyone looked at each other after hearing this.

"This is a huge project." As an expert with rich experience in military strategy and political strategies, Aragon said in a deep voice.

Arwen nodded, and she supported everyone who was supported by her fiancé Aragon.

Du Yu smiled slightly and pointed to the huge rock that was almost as tall as the city wall: "Our construction was not built out of thin air. The name of the Holy Helmet Valley was the horn castle. It was the horn sound similar to the horn when the mountain wind blows into the deep valley. After thousands of years of magical craftsmanship in nature, this rock still stands here, which shows its strength."

After everyone looked closely, Wang Yuyan couldn't help but say: "As my cousin said, this rock is a whole piece of granite, very strong. Even if the catapult hits the stone, it will never loosen at all."

Aragon glanced at Jin Li. The dwarf who was good at construction shook his head and said, "Even if there are huge rocks as the middle beam, it would take at least 50,000 dwarf craftsmen to build such a large city wall within less than a month of Sima Yi's invasion. With our existing manpower, it is not even enough to complete half of the projects. When the enemy came, he found that we were so tired that we were unable to raise our weapons. This was funny!"

Du Yu nodded and turned to Keillandriel: "I know there are many Mellon seeds in your hand. Can you use the power of plants to speed up the construction?"

His ideas were so wild that Gellander was stunned. And opponents such as Aragon were even more invisible.

Arwen said coldly: "Our elves' plant seeds are hard-won, how can they be consumed in this barren land?"

Unexpectedly, Gellandriel's beautiful eyes suddenly lit up.

"Yes, you are so smart!" The elf queen said in surprise: "The power of plants is great. A weed can break the rocks and break the rocks out! If you use Mellon seeds to mix the large rocks everywhere in Shiliheng Mountain. One month is enough to form a wall of mixed stones and wood. But the problem is that, in addition to this large rock, there is a lack of other Mellon branches that can grasp the support point for rooting. If this section of the wall is built, it will be at least 2,000 meters."

Arwen said, "That's it! That's it! How can a bare big stone support the growth of the entire city wall? At least it needs a rock like a flying stone from the sky, and it must be huge in size to be expected to be completed."

"Need a flying stone from the sky?"

Du Yu smiled slightly and took out the treasure from his arms!

Heart of the Castle!

This treasure, which can be called a defensive weapon, emerged from the disdainful eyes of Aragon, Arvin and others!

Keirandrel, Legolas, Jinli and others stared at the castle flying out of the sky in a daze, suddenly flew out of thin air and appeared on the vast valley entrance!

This castle is filled with fairy spirit, with 7 arrow towers, towering city walls, defensive covers surrounded by fairy spirit, complex Qimen Dunjia Love Flower Array, moat surrounded by poisonous water, and carefully designed Lu Daozi mechanism, which lies between heaven and earth, echoing the naturally formed huge rock, forming the grand momentum of the Double Ghost Gate!
