An hour later, a message that made Xu Ziye speechless came from the Jizhou Castle. The assassin was already dead in front of the second level of Jizhou Castle.

However, in the end, his soul did not turn into a new oil painting as Xu Ziye thought, but turned into a brochure with a bronze book cover, which recorded the practice of the academic assassins.

Although the practice method here is only half as high as this assassin, it is quite useful for most assassins or killer organizations.

From these practice methods, they can see what is missing from their subordinates.

But for a necromancer like Xu Ziye, this is useless. Turning the assassin into an oil painting. When an enemy enters the polar day castle, it can turn into a soul assassin to attack the enemy.

But after it turned into a bronze book, what's the use for Xu Ziye? He couldn't build an assassin academy in his half-plane to train various assassins.

But things have become like this, and Xu Ziye has no way to change anything, and it is even more impossible for the assassin to be resurrected and transformed again.

In the end, he had no choice but to take away the academy assassin training manual and return to his semi-plane.

Compared to the last time when he left, Xu Ziye's semi-plane became much larger, and the properties of the entire semi-plane gradually changed, and there were many black fog in the sky, which was a mixture of negative energy, resentment aura and undead aura.

As long as the necromancer stays for a long time, it will slowly become like this, rather than the necromancers who like to stay in the darkness.

The ground has been completely assimilated into the ground unique to the undead plane, corroding the mud.

At this time, the entire half-plane was filled with this soft purple soil. After stepping on it, it felt a bit strange.

However, when Xu Ziye stepped on, he would feel the breath of the undead quickly spreading into his body from under his feet. With his current strength, as long as he did not leave the ground, his magic power would not be consumed.

This is exactly the effect Xu Ziye wants. Under this change, the undead soldiers in the semi-plane will be terriblely strong in combat, and they are more susceptible to Xu Ziye's control.

Xu Ziye was also very happy to see the changes in his semi-plane. Of course, what he wanted was not just that. After putting all the things he brought on the ground, Xu Ziye just pointed to the ground, and the ground was like water waves, sending all these materials to the place where Xu Ziye wanted.

Looking at the materials sent away, Xu Ziye didn't look happy because this method consumed too much energy from the half-plane.

If Xu Ziye had a choice, he would rather let the skeleton soldiers who would not be tired from transporting these things.

But now he has nothing, so he can only consume it like this.

With such helplessness, Xu Ziye quickly turned all the drawings and materials he brought into various buildings.

The first thing to be completed is naturally the Soul Conjuring Tower and the Undead Control Tower on the Five Rays Formation. Although these two towers are holy images of the Dead, they are not shorter than normal magic towers.

The Soul Conjuring Tower looks like a huge obelisk, with the blue stone material engraved with silver magic patterns and various texts.

Although it has just been built, it can be seen that countless ghosts are constantly gathering towards this side.

This is exactly what all necromancers need. In addition to forcibly extracting the souls killed by the necromancer and transforming them into soul crystals, the soul-summoning tower also has the function of protecting the souls under the necromancers to protect the souls.

It is the most necessary building in the city of Necromancers. Of course, if Xu Ziye is so big, only the large main city of Necromancers can have it. It is good that other Necromancers can often have a soul-summoning tower of the same height in the hands of other Necromancers.

Compared with the Soul Conjuring Tower, the Undead Control Tower looks even more gorgeous. The Undead Control Tower is not something that ordinary Undead Mages can use. Only a army of undead with more than 10,000 people need the help of the Undead Control Tower.

The undead control tower under Xu Ziye is as tall as the other towers, and can at least control tens of millions of undead troops at the same time.

Such a deceased control tower naturally looks extremely gorgeous. The entire tower looks like a display stand for various undeceased soldiers, from the lowest level of skeleton soldiers to the highest level of death and ghost dragons. Anyway, as long as the undeceased soldiers you can think of, you can find them here.

However, these undead troops did not stay on the tower surface of the undead control tower. They looked like they were constantly twisting and forcibly scrambling into the tower body.

This is also the style of the Undead Control Tower. After every undead mage with the Undead Control Tower collects one more undead warship, he will come to the Undead Control Tower to visualize and transfer his new troops into the Undead Control Tower.

Generally, the undead control tower of the undead mage is getting bigger step by step.

But for Xu Ziye, there were enough drawings from the beginning, and he also had the development of the undead troops in the next few decades.

So at the beginning, his undead control tower had reached a relatively high level.

When the undead control tower and soul summoning tower named Wugu and Qinghun were in place, the three previous magic towers also lit up at the same time, and a huge five-pointed star appeared on the ground.

Then the space of the entire semi-plane vibrates slightly, and the style of the entire semi-plane changes rapidly.

If the previous undead aura and corroded mud only changed the properties of this semi-plane from the surface, then the completion of the pentagram array fundamentally changed the properties of this semi-plane.

When this semi-plane completes its expansion, its attributes will be determined as the innate deceased semi-plane.

Instead of being an ordinary semi-plane that is more suitable for human attributes as before.

This is exactly what Xu Ziye thought. With such a semi-plane, he can recruit more strange or capable undead guards through various means to enrich Xu Ziye's own strength.

As for his own level, Xu Ziye had never thought about it at this time.

Although he was a necromancer in his knowledge department, he never had his own city. Many times he was working hard to turn his most limited power into the most powerful force.

In order to complete more tasks, he always kept improving his strength, but instead stopped to take a look at what progress he had made in his research.
