The milky white fibrous roots swayed for a long time, felt something, and slammed down on the gray board below, penetrating the board and touching the transparent liquid.

The moment it came into contact, the milky white fibrous roots twitched slightly like an electric shock, and then grew violently.

"Brush, brush!"

With the naked eye, one after another milky fibrous roots grow from the heart of the tree, penetrating the matrix plate and soaking into the flowing nutrient solution.

"Knock knock!"

The sound of a human gulping water sounded, and many nutrient solutions were absorbed by the milky white fibrous roots, and the height of the nutrient solution in the glass pool began to decline significantly. As a result, a buoy near the input pipe also followed, and the buoy was connected to the valve of the input pipe, which immediately opened the valve and became larger, resulting in a larger flow of nutrient solution. Little by little, the liquid level in the glass pool began to rise again, and finally it was in a dynamic equilibrium.

The fibrous roots are increasing in number and length, and the ends are rapidly extending, exploring farther afield.

Within a few minutes, half of the glass pool was occupied by dense fibrous roots.

After a few more minutes, the fibrous roots occupied more than half of the glass pool.

After a few more minutes, the fibrous roots almost filled the entire glass pool and tried to get out of the glass pool.

As a result, when these fibrous roots clinged to the glass plate, the lines carved on the surface of the glass plate quickly lit up, flashing with a crimson light.

"Thorn!"

The spell flame flickered, and the smell of burnt paste was born, and all the fibrous roots that came into contact with the glass plate were burned, and even a large patch of fibrous roots that were relatively close to it turned gray-black.

Magic Pattern...... The old lich's eyelids jumped.

After being attacked, the remaining fibrous roots shrank as if they had wisdom, keeping a distance of more than 20 centimeters from the glass plate, no longer reckless and tentative, but instead absorbed the nutrient solution exclusively.

After more than ten minutes, the top of the heart of the tree cracked, and a slender light green sapling emerged, growing taller and taller.

When the sapling grows to more than 20 centimeters, the growth rate stagnates slightly, and dense branches grow on the sides, which continue to extend and twist, and finally weave into a somewhat abstract human face.

"Squeak Crunch ......"

The branches squeezed and rubbed against each other, and a strange sound sounded, gradually turning into some old human voices, and it was the giant tree of tin wood that had successfully recovered.

The human made of twigs looked at Richard, and the voice of the giant tin wood sounded, and before Richard could explain anything, it had already deduced a lot of things with its own wisdom.

"Intruder, is that you?, well, I was a bit surprised, I didn't expect that after I came back to life, we would meet again. Let me see, this seems to be a special independent space, the two invaders who were with you before were not here, could it be that you took my tree heart alone and brought me back to life?

In this case, it is a bit strange, because in my opinion, the three of you wanted to destroy me very much, how could you suddenly change your attention? Could it be that you were all pretending to deliberately deceive those two people before, and then secretly save me?

But what was the reason for you to save me? Kindness? Hehe, it's definitely not kindness, the so-called kindness is just a beautiful lie made up by you human beings. The reason why you saved me must have a plan, and this plan is something you can't get by killing me, that's why you try to resurrect me. What could that be?"

At the end, Ximu asked, and the face of the person made up by the branch showed a rather meaningful expression.

Richard glanced at Ximu, did not be verbose, and said straight to the point: "I do have a plan for you, and the thing I plan is very simple, that is, the energy you bring." You've said that you have the title of 'Source of the Forest', and you've created a powerful storm of energy in battle, so if I'm not mistaken, you can gather energy and use it, right?"

"Yes. Ximu admitted, "Intruder, you guessed it right, I can indeed gather energy for use - I can absorb a lot of energy directly from the void, regardless of space and any environmental influences, and use it to grow myself, or help the rest of life evolve.

In fact, apart from the fact that I needed some external energy and material replenishment to revive my tree heart at the beginning, I can now be self-sufficient to a certain extent. ”

As he spoke, Ximu stretched out a branch, and a dazzling purple arc flashed at the end of the branch, which lasted for more than ten seconds before dissipating, as proof that it was not lying.

After proof, Ximu looked at Richard and asked, "Okay, intruder, you have seen my ability and know that your plan can be realized, so what do you want to do next?"

"Cooperation. Richard said, "How about cooperation?"

"Cooperation?" Ximu grinned, "Can I make a bold guess that if I refuse to cooperate with you, you will threaten me with death?"

"Nope. Richard shook his head and looked at Ximudao, "It's not a threat, it's going to take action." If you refuse to cooperate, then you are a useless but dangerous enemy to me, and I cannot let you continue to live, and the most rational thing to do is to completely erase you from this world. ”

"......" Ximu was silent for a while, and then spoke up, "I have to say, I admit that you have this ability - before, you were able to defeat me with a complete body, and now it is naturally easier to erase my traces." But then again, I can't think of a last resort that you wouldn't do that. ”

"That's true. ”

"So, can I negotiate with you with death in reverse?"

"Huh?"

"You see, you want to get my energy, and I want something other than life. I will not succumb to you just for the sake of life and let you be at your mercy, that kind of future is hopeless for me, I would rather die. And if I die, you will find nothing. Although my loss is great, it is also a loss for you. Ximu Dao, at the end, paused, "What do you think?"

Richard's eyebrows raised slightly, stared at Ximu for a while, and said, "What do you want besides life?" I hope you don't go too far, otherwise I'd rather lose than take too high a risk." ”

"No, no, no, you're too worried. Ximu's tone softened a lot, "What I want, it's not too much at all, and it won't let you take any risks." ”

"What the hell is that?"

"Freedom. Ximu spoke up, "What I want is freedom." If you promise me, then we can work together.

You want energy, right, if you let me grow for another week, I will have the ability to absorb an infinite amount of energy from nothingness, and nine-tenths of it will need to be used for myself, to transform my life. The remaining tithe can be dedicated to you. Don't be too little, even a tenth is enough to supply hundreds of thousands of trees to grow, and it can fully meet all your needs.

I can keep this cooperation for ten years, and after ten years, I will be able to evolve into a completely different state of life, free from many constraints, and have the potential to evolve to the ultimate life. At that time, you are to give me back my freedom and let me leave from you. ”
