Xiao Zi's combat effectiveness, under Liu Wen's blessing, looks extremely perverted.

Although the two cat demons were extremely fast and their claws were also sharp, under the attack of Xiao Zi's millions of vines, they quickly hated the spot.

In the information that Liu Wen got before, there were some things about this kind of cat demon.

These two cat demons are the same breed as the tree life on Earth.

Moreover, in this world, only tree life is reproducing.

Liu Wen even had some suspicions that this world might be similar to the earth in the past, and there were also mutant beasts and zombies.

It's just that with the evolution of species, the intelligent creatures in this world, such as humans, as well as mutant beasts and zombies, do not evolve as fast as tree life, and are finally eliminated by tree life, leaving only this one population.

After killing the two cat demons, Xiao Zi naturally sucked their corpses into dry corpses, and then took out the demon cores in their bodies.

The tree life in this world has crystal nuclei in their bodies, but according to the information Liu Wen obtained, in this world, they are demon cores.

In this world, the tree that can produce trees and life is called the mother tree.

The life of the tree produced by the mother tree is called a demon.

In the demon's body, there is a demon core.

The Demon Core can increase the level of the mother tree, and the mother tree of the first level is upgraded to the second level, which requires 1,000 demon cores.

And the first-level mother tree can give birth to up to ten demons.

The first-level mother tree, and the pregnant demon is only one level.

The first-level demon has only one force in strength, and in this world, it belongs to a low-end existence.

As for the number of demons conceived by the mother tree, it is fixed, which is not that the mother tree cannot produce more demons, but that it cannot afford to raise them.

Matter is conserved, and it is true that the demon's combat power is strong, but the demon also needs to be fed every day.

In an ordinary time, the supply that a mother tree can provide is only enough to sustain ten demons at most.

It's like, a lot of people can afford a mobile phone, but the call bill is intimidating.

Normal people, who are dying, only have a few mobile phones, two or three calling cards, and more, they can't afford the minimum consumption every month.

In contrast, some large companies are different, they are rich and powerful, and they can support more.

Of course, in the body of the mother tree, there are also things that Liu Wen is very interested in.

For example, the mother nucleus and the life seed.

The mother core is the core of the mother tree, and this thing has always been used as a demon core in this world.

However, in Liu Wen's eyes, it would be a bit too wasteful to use the mother core as a demon core.

A human like Liu Wen can't use a demon core, but he can use a mother core.

In other words, if Liu Wen wants to improve his strength, he must kill the mother trees and obtain the mother nucleus in their bodies.

Compared to the mother nucleus, the life seed is a very magical thing, and their function is equivalent to the child of the mother tree.

When a mother tree dies, the lifeseed in its body can grow back, or it won't be long before it becomes a new mother tree.

Of course, a mother tree that has reached level seven or eight, after it dies, its life seed grows again, and it can only be level one.

Another problem is that not all mother trees have life seeds in their bodies, and this thing depends on luck.

And it doesn't have to wait for the mother tree to die before it has a chance to grow.

The seed is equivalent to the seed in the mother tree, and when it matures, it will automatically leave the mother tree and begin to grow.

Generally, the life seeds that grow naturally are sent to a safe place by the mother tree that gave birth to it, and the demons under its hands, and then planted in the land.

It's just that the life planting thing has been conceived for too long.

The competition in this world is also fierce, and it is difficult for a mother tree with a relatively low level to nurture a life seed to maturity.

Often, in the process of gestation, they are killed because of a fight with other mother trees.

However, what is more amazing is that once the mother tree dies, all the energy in its body will automatically be transferred to the life seed.

Hits that are not ripe will mature the moment the mother tree dies.

Moreover, this world has the rules of this world, generally one mother tree kills other mother trees, and the killed mother tree is pregnant with life seeds, and they will not destroy life seeds.

In the final analysis, some mother trees are still the same race.

As for the fight between them, the son is just a kind of weak meat in the process of improving their strength.

The weak are fed by the strong, and the strong are stronger to support the progress of this race.

"Oh, that's good!"

Between Liu Wen and Xiao Zi, there is a heart-to-heart connection, and he can feel Xiao Zi's situation.

When Xiao Zi absorbed the corpses of these two cat demons, Liu Wen also got a lot of information from Xiao Zi.

The corpses of these two cat demons alone provided Liu Wen with 200 million units of extraction essence.

In other words, the corpse of a cat demon is worth 100 million units of extracted essence.

Extracting the essence is Liu Wen's capital to settle down.

This thing can not only increase the level of the mutant plants under Liu Wen's hands, but also sell them to the outside.

Some time ago, Liu Wen only sold 100,000 units of extract essence to the Yanjing base every day, and he had already made a huge gain.

"Huh?"

During the inspection, Liu Wen suddenly found another news that surprised him.

Xiao Zi clearly handed Liu Wen an emotion, it wanted to swallow the two demon cores.

Originally, Xiao Zi's way to improve her strength was only to extract essence.

Now that Xiao Zi has shown interest in the demon core, Liu Wen seems to have inadvertently opened the door to Xiao Zi's new upgrade.

To be honest, if Xiao Zi can only rely on extracting essence to upgrade, it is estimated that it will not be long before it will be eliminated.

The current Xiao Zi, if it weren't for the fact that he had a large number of vines, the speed of quickly recovering the vines, and Liu Wen's plant ability was doubled, the battle just now, the Kendi who won was not Xiao Zi.

The key to the battle just now was Liu Wen's plant ability, which doubled Xiao Zi's strength.

"Try one first!"

The demon core is a red spherical crystal, like a ruby, which is very beautiful in the sun.

Feeling Xiao Zi's desire to swallow, Liu Wen decided to try the water.

"This..."

Under Liu Wen's order, Xiao Zi used vines to wrap one of the demon cores.

This demon core, which was surrounded by Xiao Zi with vines, was quickly absorbed by Xiao Zi.

And Liu Wen's side also quickly felt the improvement of Xiao Zi's strength, and Xiao Zi at this time also reached the strength of the Force.

"Swallow this one too!"

Seeing that Xiao Zi swallowed a demon core and raised his strength to a force, Liu Wen was quite excited in his heart.

Without thinking too much, Liu Wen commanded Xiao Zi to swallow the remaining demon core.

In case Xiao Zi can improve the Force a little more, then it will be earned.

"Hey..."

However, the good thing that Liu Wen was thinking about in his heart didn't work out after all, Xiao Zi swallowed the second demon core, but there was no reaction at all, and the force was still a little.
