Ryuji's guess was correct, after dealing with the obsession in the hearts of the undead, all the undead came to their senses.

They didn't need the lizard's corpse to command, they spontaneously took control of the Underworld Light Solar Ship, preparing to go in a certain direction.

Ryuji stopped them: "It's okay, you control the ship to send me to this position, I'm going to camp here." ”

When the solar ship flew down, Ryuji also thought about the situation in the underworld in front of him.

Although he temporarily solved the influence of the underworld on the undead of his men, he could not stay here forever.

It is obvious that the influence of the underworld on the undead is continuous, and Ryuji saved his own undead this time, but it is impossible to stay here all the time to treat his own undead.

And Liu Zhi has more than these undead under him, it is impossible for him to follow up every time he comes in, and Liu Zhi must find a way to deal with the situation in front of him.

When the sun ship fell to the position designated by Yanagi, Yanagi already had a plan in his heart.

After disembarking from the ship, Ryuji did not rush to let the Solar Boat Underworld Light leave, but took out another architectural plan for the camp, the War Ancient Tree.

It was something that looked like a giant tree with facial features, and after Yanagi activated the ancient tree of war, a green light spread out in all directions centered on him.

This green light was quite thick, and it directly expelled the thick gray fog of the underworld.

Under this green light, Ryuji quickly made a choice, his target this time was not to attack, so he chose the defensive form of the War Ancient Tree.

After making a choice, the ancient tree of war changed from an illusion to a physical entity, and then directly rooted in the earth.

Then green plants rose from the otherwise barren and dead land.

These plants withered quickly as soon as they grew, and it can be seen that under this concentration of yin qi, there is no way for all life to survive for a long time.

But Ryuji didn't care about this, he brought the design blueprint of the camp of the War Ancient Tree to the underworld, and he didn't think about turning it into a natural paradise, but wanted to use his years of research on the underworld ecosystem to set up this camp.

Liu Zhi's research in the underworld ecosystem for more than ten years not only gave him the opportunity to advance to level 5 of the necromancer, but also made up for a lot of knowledge that he didn't know.

Through this knowledge, Ryuji slowly pieced together some things about the Id family.

For example, how did the idea of their underworld ecosystem come about, and then how far the underworld ecosystem can finally go?

Ryuji also has a lot of ideas about how to use the War Ancient Tree.

For example, how the War Tree should be planted in the Underworld, and how to move some things from the Underworld biome to the camp built by the War Tree.

The problems that Ryuji is facing now are all considered at the beginning, at most these problems are more serious than he imagined, but they are not beyond the scope of his imagination.

As soon as Ryuji saw this happening, he immediately took out a red bottle of potion and poured it into the root of the Ancient War Tree.

This potion is a special potion made by Ryuji in the Idd plane, using the power of the plane and his own Quetzalcoatl divinity plus the ability to harvest.

This potion can be used to replenish the life force of the Legion.

It can be said that just such a small bottle of potion can resurrect all the members of the three major legions under Liu Zhi.

It is precisely because of such a powerful effect that Liu Zhi only has a total of five bottles of these potions in his hands.

Now is the perfect time for Ryuji to use this potion.

At present, if Liu Zhi wants his own camp to camp in this place successfully, he must replenish enough vitality for the War Ancient Tree.

With the fall of the Yanagi potion, the plants that had begun to wither grew rapidly, all of them were small plants such as thorns, they grew aimlessly at first, but as the ancient trees of war took root, these plants began to grow around some clearing of their own accord as if they had been affected.

The locations are quite characteristic, and each of the clearings is surrounded by a large number of thorny walls.

In total, there are three large spaces of more than 1,000 square meters, five medium-sized spaces of 1,000 to 500 square meters, and eleven small spaces of about 500 square meters.

Ryuji stood under the ancient tree of war, watching as the clearings were surrounded by thorns, and finally all the thorns grew bigger and bigger, forming huge walls.

The newly grown thorns were the thickness of a normal human arm, and the black thorns had many green lines on them.

Ryuji had been standing here and watching, watching the thorns grow upward, and after growing to a height of about thirty meters, they began to converge towards the center, and finally formed a huge thorn cover, covering the entire camp area.

It felt like the razor heights of World of Warcraft, completely enveloped in giant thorns.

At this point, Ryuji finally breathed a sigh of relief, and he worked under the ancient war tree for a few more moments, and the thorns began to sort, and the thorns on the outermost part of the camp quickly thickened and hardened, covered with barbs, and some strange flowers also grew.

Any moving object will become entangled in the thorn and eventually become the nourishment of the thorn.

The brambles inside the camp began to shrink and turn green, and a large amount of green gas was spewed.

This is prepared to fight against too thick yin qi.

This was originally a situation specially designed by Liu Zhi when he was studying the underworld ecosystem, in order to allow some creatures to transform into underworld creatures in a short period of time.

In this case, a closed area is created, and the concentration of yin energy inside this area is adjusted to speed up or slow down the underworldization of ordinary creatures.

Originally, Liu Zhi wanted to speed up the underworld transformation of creatures, but he didn't expect that here, it would become the best magic weapon to reduce the influence of yin qi on the undead.

As the total amount of yin qi in the camp dropped to a normal level, Liu Zhi finally breathed a sigh of relief.

Directly below the Ancient War Tree, he set up a teleportation array.

And the location of the plague camp began.

After all, the situation in the underworld interrupted some of Liu Zhi's plans, and he originally planned to directly open a teleportation array after arriving in the underworld and drag the undead here.

I didn't expect this to be the case in the underworld here, of course he didn't dare to bring the undead troops over at that time, and at that time, he was more or less sent to death.

Now that it's hard to get better, Liu Zhi has to send a batch of undead troops over quickly, and find a way to deal with the situation in the underworld.
