This method is mainly to catalyze the energy in the undead stone and release all the energy in it at once. In this way, the undead power in the barrier will be quite strong, and the soul of the world saplings will also struggle strongly from the beginning, then to the intermittent struggle, and finally it will not move.

Moreover, the spirit body also changed from green to dark green. Xu Ziye threw several undead stones one after another and began to transform further.

Finally, the soul of the World Seedling was transformed successfully! Xu Ziye removed the barrier, and the demonic patterns on the undead appeared, which proved that Xu Ziye could freely control the undead.

Xu Ziye stuffed the undead of the world sapling back into the tree body, and the foundation below began to automatically collect yin energy. When Xu Ziye saw this scene, he immediately opened the gas-gathering cylinder and threw it into the dense roots of the tree.

However, this transformation is still harmful. The world sapling had three layers of leaves, but now it has no more than one layer. However, if it grows leaves again, it is a medicine that is beneficial to the undead, and it is a poison to the living creature.

The foundation began to automatically collect yin energy, and the entire world sapling seemed to come alive. All the undead stones on the rhizomes lit up, continuously providing undead energy to the world saplings. The magic patterns on the tree also began to expand. Every time Xu Ziye amplifies a little, he has to use exponential magic power to pay. It is much harder to control such a large sapling than just control the soul.

"Olenme! Give me magic power!" Xu Ziye said. Now Xu Ziye feels that his body is almost exhausted.

Oremé didn't say anything, but started to deliver magic to Xu Ziye. At this time, Bluetooth also moved, and immediately used the undead magic to assist Xu Ziye in controlling it. Green was ready to attack. Once the world saplings were out of control, he would control the world saplings as soon as possible.

The magic pattern became bigger and bigger, and finally it was a hundred meters long. When they heard it, Xu Ziye and Orenmei stopped their magic power output. Xu Ziye looked at the magic pattern on the tree. This was the largest magic pattern he had ever made, and the most difficult magic pattern.

Now the Tree of the World has been successfully transformed into a sapling of the undead!

This kind of undead sapling is suitable for planting in places where there are already many dead people on the battlefield, preferably in extremely dark places and in dark places. All previous habits must be reversed.

"Master! Congratulations!" said Oremme.

"This is too early," Xu Ziye said with a smile: "Now it can only be half done. Take a break and there is still something to do later!"

"There is still something?" Orenme was completely stunned after hearing this: "The transformation has been successfully completed, what else is there?"

"If it's yours, what do you plan to do after the conversion is successful?" Xu Ziye asked back without answering.

Orenmei thought for a while, and then said to Xu Ziye: "If I were its master, then I would plant this sapling in my own territory to provide all the undeads in my legion. Although the undead legion is obviously different from the human legion, it is best to replenish supplies if there is one, and it can also be used to create more powerful undeads. In addition, during war, it can also be moved to the battlefield, which can not only suppress the opponent, but also absorb the yin energy and undead to promote its growth."

Xu Ziye nodded: "But such a large sapling may weigh tens of thousands of tons. Even if you want to move it, it will be difficult for you to move it. So how do you move it to the battlefield? Moreover, the battlefield changes rapidly. Once it is defeated by the enemy, the undead sapling will be taken away by the opponent. And how do you grab such a big thing? Even if you grab it, how much time will it take to transport it? You are also an old man who has been through the battlefield for a long time. You should be very clear that the consequence of this waste of time is to encounter an enemy's attack!"

"This..." Orenmey had nothing to say, because everything Xu Ziye said was reasonable. The goal of the seedlings was too big and they could not be transported freely. In this way, it would not only not play the role it should have on the battlefield, but also become a burden. If you don't do that, just keeping the seedlings at home, then the price you paid was obviously not worth it.

"So, I need it to do more than just this, I want to integrate with it!" Xu Ziye said in a surprising way.

"What!" Orenmei grew up with her mouth in surprise.

"I had this plan from the beginning, and after I read Clayty's Magic Pattern Book, I was even more sure that this method would work, but I was the first person to do this, and no one knew what the result would be after the failure of the fusion!" Xu Ziye said.

"Master, isn't this too risky?" Oremme asked, because there is a certain probability that the soul fusion will fail. Not to mention that two different species are fusion, even the same species will have the probability of failure, and the price of failure is that the two souls will dissipate.

Moreover, it must be integrated synchronously with the soul, which is necessary. In this way, the risk is no different from an exponential increase.

"The probability of success is 32%, it is worth trying!" Xu Ziye said.

Oremé didn't say anything anymore. Even if it was a 50% chance, he was unwilling to do such a thing. Even if the fusion was successful, who would know what kind of monster the fusion of different species would become?

Of course, Xu Ziye knew this, but he was seeking wealth and danger. How could he win if he didn't take risks? There are many forces that are stronger than him. If he doesn't become stronger, it will be a matter of time before he is swallowed by other forces. The reason why he can fight against some weaker forces is that the high-level forces do not take him seriously at all.

Xu Ziye was determined to change the status quo, so he had to take risks!

"Master! Are you sure you want to go to the next step?" Lu came over and asked.

Xu Ziye nodded: "Of course, let Lan be prepared. I'm relieved that you two are by your side. Oremme, you are still helping us deliver magic. If the magic is not enough, there will be half a box of undead stones and black gems there. Which one do you think you need it!"

Oremé nodded.

Xu Ziye continued, "Once something happens to me, then your new master is Enni. Do you understand?"

This statement is almost equivalent to giving the last words. Everyone feels uncomfortable when they hear this, but they still answered together: "Yes! Lord!"

Xu Ziye nodded, then looked at the undead sapling, walked over slowly, sat cross-legged beside the sapling, and said to Lu: "Then let's start!"
Chapter completed!
