After the installation of the fixed buildings, Liu Zong directed the men to build the two closest walls to the city, which according to the original blueprints, were the two highest and thickest of the city's main walls.

The walls should be about ten meters thick and nearly seventy meters high, so even adult creatures like Beamon would not be able to climb the walls directly.

Outside this wall is the shooting wall, between the city wall and the city wall is the hiding hole, the second shooting wall is fifty meters high, on which are placed two magic towers and seven shooting towers.

The outermost part is a 35-meter-high patrol wall, which is used to warn and deal with ordinary enemies, this wall only has defensive tools such as catapults and ballistas, but there are many defense towers between this wall and the shooting wall.

These walls take a lot of time to build, Liu Zong only has a week now, naturally it is impossible to repair all the walls, he can only choose to build the highest main wall, the other two will have to wait for later.

When repairing the city wall, Liu Zong also began to deal with the other side of the mountain wall, here Liu Zong placed a gate made of white bones, this gate is directly embedded in the mountain wall, the height is a full fifty meters high, the width is also thirty meters wide, in front of the gate is a pile of bones made of white bones, it looks quite gloomy.

In the middle of this gate, Liu Zong had a huge stone tablet thirty meters high moved and forcibly inlaid it on the mountain wall.

After all this was done, Liu Zong nodded with satisfaction, this was the Heroic Soul Tablet he had prepared.

This Heroic Soul Monument was specially prepared by Liu Zong for this city, and all the soldiers who died in the defense of this city will all follow the guidance of the Heroic Soul Monument into the kingdom of God.

Of course, this is just external publicity, in fact, this is a reinforcement of Liu Zong's [Huangquan Road], although the heroic soul monument is made of stone, but the appearance is the appearance of Liu Zong's spear, and the gate of the white bone is also the appearance of the ghost door opened by Liu Zong [Huangquan Road - Opening the Ghost Gate under the Moon].

Liu Zong also carved the spell of spiritualism on the mountain wall, it can be said that as long as there is enough energy, this is the non-stop [Open the Ghost Gate Under the Moon] skill, and the powerful power will always support the operation of this ghost gate, sending the souls who died in battle to the underworld.

And Liu Zong only needs to come over every once in a while to deal with the Heroic Soul Monument, not to mention anything else, at least his [Open the Ghost Gate Under the Moon] trick will get a good growth.

After completing the construction of the Heroic Soul Monument, it was already the fifth day, Liu Zong hesitated for a moment, and finally transported a large amount of undead materials from the Canglong Fortress and began to build another building, the Path of Bones.

This path of bones is a road arranged on both sides of the valley, and when it is fully built, a large number of bones can be seen in the dirt of the entire valley at any time.

These bones are the building material of the Yanagi sect, so they are not affected by the fog of the undead, but will affect the enemies who die here.

This time this city is not the city of the undead, so Liu Zong does not need too many corpses, the enemies who die here, the corpses will be affected by the path of bones, and they will turn into white bones as soon as possible, becoming part of the path of bones.

As for their souls, they will be transmitted to the ghost gate behind the Heroic Soul Monument along a secret passageway, and converted into the energy needed by the city.

Of course, the path of bones is aimed at all small and medium-sized creatures, and large creatures such as dragons will not be directly transformed into bones even if they die in battle, which is really wasteful.

So as long as the battle is over, most of the dragon corpses will be taken away by the winner, if the other party wins, then the dragon's corpse is likely to be transformed into a bone dragon or something, and if Liu Zong and they win, then the corpses of these large creatures will be peeled and used to make items or something.

Liu Zong was very interested in the corpses of these large creatures, and his research on bone dragons had reached a certain level, and now he was close to making bone dragons from real dragon bones.

However, he was not often in the city, and he could not show that he was very good at undead spells, so he could only watch the corpses of these dragons be decomposed.

However, the corpse is useless, it does not mean that the soul of the dragon is useless, and the third special building of Liu Zong, the Dragon Slayer Valley, is used for this.

Liu Zong did not require all the dragons to be led to this valley to kill, he just opened a valley-like passage near the mountain wall, and all the dragon souls that were killed would be guided here and stored, so as not to be secretly led away and transformed by the Heroic Soul Monument.

The Dragon Slaying Valley has a certain influence on the dragon soul, and it can keep the dragon soul for nearly two years, during these two years, the dragon soul will slowly emit a power outward, affecting everything in the valley, maybe there will be no bad changes at first, but after a thousand years, this valley will definitely produce something that makes Liu Zong's heart move.

Of course, it will take a long time to establish this location in the Dragon Slaying Valley, and Liu Zong doesn't have time to do this now, so it is already very good that he can pave the path of white bones.

In fact, when he paved half of the path of bones, there was already an enemy on the other side of the valley near the wilderness, which was the orc force force that had received the news and rushed over.

In the wilderness, the orcs are the best force to gather, they usually deal with the state of readiness, as long as they get the order, they can set off immediately.

This time it can drag on for more than a week, entirely because the undead and the dungeon side have also received the news, they want to unite again, but they are slower to send troops, the undead side is fine, just call a few corpses, but the dungeon side has to wait for those dragon masters to get ready.

Some of the anxious orcs rushed towards this side of the valley without hesitation.

These orcs are only the vanguard troops, the number is not large, about five hundred, because they are used to explore the road or something, so all the troops sent out are fast troops like wolf cavalry.

Upon entering the valley, the wolf cavalry immediately noticed that all the trees they had just cut down were gone, replaced by a kind of bone ground.

For wolf cavalry who have killed too much, they are also common with white bones or something, and they have also dealt with the undead forces, and they are also familiar with this style of situation, so they all think that this is made by the undead forces, so they don't care much.

It wasn't until they rushed to the halfway point of the valley and encountered the first wall that Liu Zong had just built, that they realized that the valley had been blocked by someone, and they couldn't cross it now.
