There is no doubt that this is a huge project. The moment the magic array lights up, Xu Ziye felt that the magic power on his body was rapidly losing. The black gems on the magic array light up one by one, and they are constantly providing energy for this huge array.

The origin of the world sapling is vitality, so it should be transformed into a dead soul like an ordinary corpse! The world sapling is different from ordinary plants and has a certain soul, so this time it mainly aims to awaken the world sapling and turn its soul into an undead.

Once successful, the original power of the world sapling will no longer be vitality, but the power of the undead!

In other words, it can continuously provide energy to the undead, so that it can greatly save the undead stone. Moreover, what the world seedlings absorb will no longer absorb sunlight and light energy, but will become yin energy and souls!

All the gems on the trunks were lit up. Xu Ziye thought it was almost time, so he gave Green a wink, Green nodded, and then took out several large boxes, which contained the essence of the undead tree, which has now become dark plants. These dark plants will be planted on the trunks of the world's saplings to replace the original trunks and become trunks that are more suitable for the undead system.

"Dark Planting!" Green pierced the dark plants in his hand directly into the trunk of the World Saplings, one after another, and the trunks of the World Saplings began to fall off on a large scale, and the dark plants inside quickly began to grow, but the bone armor of the trees was irreplaceable, but the body must be transformed into a dead body.

These dark plants gradually replaced the trunks of the World Saplings themselves, and the rest was to merge them, truly integrating these dark plants with the World Saplings.

This process was quite long, and Xu Ziye did not dare to relax for a moment. He also always paid attention to the lines on the magic pattern to see if the converted lines matched with the lines on the magic pattern. If they don't match, problems will arise, resulting in the failure of the conversion.

Xu Ziye does not have the ability to do this again. This requires a large number of undead stones, dark plants and black gems. Xu Ziye has used a lot before, and basically everything here can be said to be all. Even if it is made again, it will take a lot of time. During this period, the world's seedlings may recover at any time, and then all the hard work will be in vain.

So, you must not fail!

Time passed minute by minute, and more than ten hours had passed. Xu Ziye looked at the magic pattern line. Fortunately, everything was normal. It seemed that the fusion work was almost done. Now the entire tree body has been replaced with a completely dark plant.

But from the outside, you can't see anything. If you can see something, it only means that the integration is not thorough enough.

"Start the next step!" Xu Ziye whispered at this time. This step is a crucial step, that is, the undead's rhizome, because this directly determines the nature of the world's saplings. However, it is difficult to transform the undead. It is not only necessary to transform, but also needs to be transformed into a rhizome that can absorb yin energy and the undead.

Xu Ziye began to activate the gems on the roots of the tree, and the undead stones and black gems lit up one by one. Xu Ziye took out the gas gathering bottle, which was the yin energy collected from the cave a few days ago!

"Green! Take action!" Xu Ziye said to Lu. Green nodded, and then used dark planting on the rhizomes. Gradually, the replacement of rhizomes also began, but this alone cannot be done. You must also use the undead stone that can absorb the yin energy to succeed.

Plant the Undead Stone inside, the Undead Stone will automatically absorb the Yin Qi provided by Xu Ziye. In this way, it can drive the foundation of the World Sapling to absorb Yin Qi, making the reborn World Sapling accustomed to absorbing Yin Qi and the Undead.

Xu Ziye suddenly felt a powerful soul, like a wild beast, and was quite repulsive of such transformations. It rushed around in the barrier and did not want to succumb to its current destiny.

There is no doubt that this soul is the original soul of the World Seedling. What Xu Ziye just did, transformation is only one aspect, and another very important aspect, which is to force the original soul of the World Seedling to come out and then transform.

Xu Ziye's hand left the magic pattern. Now this step is the key to the key! It is whether he can capture the original soul of the world sapling!

A green shadow floated back and forth on the trunk, trying hard to change the trunk that had become a dark plant.

"Soul Confinement!" Xu Ziye released a green aperture in his hand, and the aperture directly covered the head of the green shadow, but the green shadow slipped away directly.

Of course, Xu Ziye would not be able to succeed in one go. This soul is different from the souls I encountered before. The souls of plants are quite rare things, and they are arranged in order according to the degree of preciousness. The first one is the natural soul, the second one is the plant soul, the third and fourth ones are the animal soul and the human soul, and the human soul is the least valuable.

"Soul-restraining technique!" Xu Ziye directly released many soul chains. These soul chains are invisible and almost ineffective for physical lives. The effect on ordinary souls is limited. It can only be restrained for a while. Xu Ziye needs this time. As long as he can bind this soul for a short time, he can confine his soul and forcefully transform it.

Suddenly, Xu Ziye sensed that his soul chain was bound to a spirit body. Xu Ziye immediately rushed over, and the green shadow was rushing back and forth, trying to get rid of the chain.

"Soul Confinement!" Xu Ziye immediately released a formation and placed it directly on the formation with three black gems. Suddenly, the light of the entire formation illuminated.

Xu Ziye took back the soul chain, and the soul of the sapling in this world would not be able to escape for a while. Xu Ziye immediately put his own magic pattern on his soul without saying a word. This is to prepare for what happened later, then took out a few undead stones and put them into the barrier.

Suddenly, the soul of the world sapling became even more uneasy due to the entry of these undead stones. These undead stones emitted undead vitality and had a lot of influence on the vitality of this light attribute.
