Through the gap passage of the underground world under his own Hades, Sandru entered the half-dimensional underworld.

The half-plane in front of me has not yet been formed, and the situation in the underworld has been somewhat affected, and the entire underworld is as big as the real world, and it looks like a reflection in the water.

Not as casual as a normal plane, the underworld may be ten times larger than a hundred times larger for more and more ghosts to inhabit.

After stepping into the underworld, Sandru still felt that this place was different from the half-plane.

In the half-plane, most of them are shrouded in the woods due to Yanagi's request, and they are lush and beautiful from a distance.

But when they reached the underworld, the ground was still the same as it was, but there were no trees, and under the gray sky, there were collapsed houses and white bones everywhere.

Looking at the situation of these houses, Sandru also looked a little sideways, before Liu Zhi made a move, he was most concerned about intelligence, although he himself did not come, but in the past few days, he had sent many people to the underworld to inquire about the news.

These scouts went back to report and only told Ryuji where there were enemies in the underworld and what kind of undead they had, but they didn't explain how this underworld was so barren.

After standing on the land of the underworld for a while, a large number of ghouls and man-eating wolves followed.

They had already undergone underworld, adapted to life in the underworld, and the new exoskeleton mecha had brought them some benefits, and as soon as they entered here, they ran in all directions.

Sandru didn't detain these ghouls and man-eating wolves, but just left the two continents of war wolves and fighting dogs by his side, and the rest were all divided into groups of 60 and released, letting them go around to see if there was anything nearby that they hadn't found yet.

Sandru knew his mission, and after sending out the skirmish ghouls and man-eating wolves, he took the staff of death and headed for a place.

That's the direction that Ryuji has been working on in the past three days.

It was the upper reaches of the river that Yanoji occupied, and there was a castle there, and according to the information that Yanoji had obtained, the castle and the nearby manor village had a total population of nearly 10,000 people.

If they really want to fight, they can recruit about 3,000 soldiers in a short time.

Among these 3,000 soldiers, there should be about two to three hundred transcendent professionals, and among them, there may be two or three of them above level 5.

Even behind them, there may be a different existence.

The reason why Liu Zhi would pick such a big guy as an enemy in the first place is entirely because their position is too good.

They were just upstream of the city of Liuzhi, and if they were to go down the river by boat, it would only take three to five hours for their troops to appear outside the Hades.

The relationship between them, no matter how you talk about it, is only the possibility of life and death, and if you want to change this possibility, either Liu Zhi will change his position, or the castle will move away.

But is it possible?

Ryuji would not believe that the castle owner's brain was in water, and in order to ensure that he would not be suddenly attacked, Ryuji of course needed to understand the situation of this enemy in all aspects.

When Sandru came, Ryuji had already passed on his thoughts to him, and for Sandru, others didn't have to pay too much attention, but in this direction, he had to come and see it in person.

Heading up the river of the underworld with a ghoul and a man-eating wolf, Sandru soon saw the shape of the ground near the castle.

Seeing the situation here from afar, Sandru couldn't help but sigh, as if he had found something different.

He glanced over there a little uncertainly, and finally pressed his hand to the center of his eyebrows.

This is how he connects with Ryuji, if in the same world, he and Ryuji hardly need to speak, and they can convey some messages through the transmission of the heart.

But in a different world, he needs to strengthen his spiritual power and send everything he sees to Liu Zhi.

At this time, Ryuji was dealing with the situation in the ghoul mountain forest.

He planned to take advantage of the fact that the ghouls and man-eating wolves were taken away by Sandru, and those little wolves and puppies were also soaked in the fountain of life, so that this place could be sorted out.

He found that the tree-bound spirit snake skeleton-ghoul system was still a bit rigid, and at this time, all the ghouls were cleared out, plus the harvest from this time, it could be sorted out.

Ryuji planned to transplant the serpent bones, snake bones, viper flowers, and Nadami to the hill where the dragon had turned into a hill, with Nadami in the highest position and the snake skeleton in the middle, and several more.

The viper flower is planted at the foot of the snake skeleton to affect the properties of the snake skeleton.

At the same time, a large amount of grass is planted at the foot of the mountain, and gophers and rabbits are stocked.

Of course, one might say, is this any different from everything that has been done before?

In fact, Liu Zhi had to do more than that, he borrowed the bones of the giant snake, Nadam, and even the ground type of the hills to arrange a huge three-dimensional magic circle.

That's why Ryuji wants to move all the ghouls and man-eating wolves out.

In Ryuji's mind, all of these arrangements exist for the sake of the circle, with the hills formed by the dragon providing the dragon's momentum to the circle, and the bones of the serpent providing the necessary foundation for the circle.

The snake skeleton wood is the key node of the magic circle, Nadam is the future of the magic circle, and the poisonous snake flower is used to strengthen the poison.

As for the gophers and rabbits that are stocked here, they are just to provide the magic circle with the life force that must be consumed.

These are the whole cycles, and the whole cycle is for the purpose of strengthening the ghouls.

In the future, when ghouls and man-eaters enter this environment, they will immediately be affected by the magic circle, and their bodies will be stimulated by the entire magic circle in all directions.

In Ryuji's words, this is an experiment, a system experiment in which the ghoul dog is taken out alone.

The goal of this experiment is to have only one goal, that is, the entire treebinder system exists around the ghouls, including the entire cycle of the biosphere.

It even includes some later developments.

While Ryuji was studying the situation here, a message came from Sandru's side.

Although it was a picture, it directly interrupted Ryuji's movements.

Looking at the picture in front of him, Liu Zhi frowned, pushed his hands forward, and directly overthrew the magic circle that was about to be prepared.

The scene he had just seen made Ryuji have a new idea, and this idea seemed more reasonable.

After overthrowing this magic circle, Liu Zhi reacted.

"Wait, what did I just do, Sandru sent back that information as if to tell me about the situation in the upper castle."
