"Maybe to be promoted to the fourth level, the wind-type source species must also be upgraded to the fourth level. Both must be upgraded at the same time in order to resolve the just-in-the-yuan riot."

"As for why the source of mental power did not cause this problem before, perhaps it is because mental power is different from the Yuan power and does not trigger some internal bond, so this problem was not discovered in advance."

Ye Chen speculated.

Afterwards, he began to use the remaining fourth-level spiritual crystals to improve the [wind-type source species], and at this time he no longer dared to break through the fourth level easily.

The dangers he encountered before also made him still feel scared. As long as he made a slight mistake just now, he might explode.

It was another half an hour, and Ye Chen also elevated the [Wind-Source Source] to the third level.

At this time, all the fourth-level spiritual crystals in his hand were absorbed.

Just as he was about to stop practicing, he suddenly realized that his [Fire Source] had actually broken through on his own. In a moment, Ye Chen found that he had inexplicably advanced to become an evolutionist of [Fourth Level].

Ye Chen was happy, and also understood that if the owner of dual- or multi-system talents wanted to advance, the difference in the levels of all talents could not exceed the first level.

Once it exceeds, it will trigger a [source type] riot, triggering a self-destruction.

After being promoted to the fourth level, he suddenly found that his combat power had undergone a qualitative change.

Now, he can transform the shield of Yuanli.

The Yuanli Shield can withstand physical damage, including bullets and shells. Of course, there is a prerequisite: your Yuanli Shield is strong enough because the Yuanli Shield will consume Yuanli.

"Now I may be able to fight against fifth-level monsters, sea beasts and zombies."

He is very confident.

Afterwards, he also announced that he would break the barrier.

When she returned to the bedroom, she suddenly found that Li Anran was still asleep. Looking at the other party's quiet appearance, Ye Chen did not wake her up. After all, she had really consumed a lot last night and needed rest.

Afterwards, he took a shower and washed away the odor caused by his practice.

Change into new clothes.

Another elegant noble man.

When he returned to the villa, Ye Xue was cooking. When he found his figure, Ye Xue immediately greeted: "Ye Chen, can you and Li Anran really sleep? Did you go to bed very late last night?"

Her words have a strong jealousy and sour taste.

"Ye Xue, there is nothing. I was practicing just now, so I didn't come out."

Ye Chen explained awkwardly.

"Don't care about you anymore. You didn't eat breakfast, are you hungry? I just prepared a fried rice and you can fill your stomach first."

Ye Xue did not continue to tease Ye Chen, but instead cared about whether Ye Chen was hungry.

"Okay, I'm just hungry."

Ye Chen said.

Ye Xue brought the fried rice to Ye Chen and poured Ye Chen a glass of water.

Afterwards, he said, "Give it, eat it slowly, don't choke."

Ye Chen was quite moved when he heard this.

Afterwards, he drank a sip of water and began to destroy the fried rice in front of him.

"Ye Chen, what happened last night? I heard gunshots."

Ye Xue asked in a low voice.

"It's okay, it's all small things, I can solve it."

Ye Chen did not explain, he was afraid that Ye Xue and the others would worry about it.

"Stop coming, I'll just ask casually."

"But you have to be careful in everything."

Ye Xue reminded.

"I understand."

......

After dinner, Ye Chen came to the laboratory.

Now, his northern area is solid, with the security system of [Fortress of Doom] and the double protection of 300 mechanic warriors, no one can break in.

No matter how bad it is, he is the top fourth-level master.

Afterwards, Ye Chen found Su Ruoxue.

“How is this recipe researched?”

He asked.

Nowadays, he has less and less money in his hands, and he needs to make money through this [Talent Awakening Potion]. If he has money, he can recharge and exchange it for evolution points.

"I have almost finished researching this. With Xiaoyu, the mechanical pet, I promise to complete the task and make this [Talent Awakening Potion]."

Su Ruoxue's understanding of biotechnology has improved a lot in the past two days.

Xiaoyu, a mechanical pet, has a lot of knowledge reserves, including biotechnology.

As an alien civilization far exceeds [Blue Star], its biotechnology has also surpassed Blue Star a lot.

She is with Xiaoyu every day, and she is really eager to learn, which delays her practice. But she doesn't mind at all. Instead, she devotes herself to exploring knowledge and absorbs new knowledge every day.

She is very satisfied.

"good!"

Ye Chen was very happy when he heard this.

If Su Ruo said that, his money-making plan would be officially launched, but before that, he would only be at ease if he had to enslave this [Little Fairy] into his slave.

Afterwards, he began to use the ss-level [god-level slavery] talent on Su Ruoxue...

"Ding, the enslavement failed!"

"Slavery failed!"

"fail!"

"fail!"

......

After many failures, Ye Chen was almost desperate. Suddenly he received a prompt from [Successful Enslavement]. At this time, he was filled with joy. As long as he controls Su Ruoxue in his hands, he will have the most powerful biology [Ghost] to help him make money in the future.

"Ha ha--"

Ye Chen couldn't help but chuckled.

Upon hearing this, Su Ruoxue couldn't help but ask in surprise: "Ye Chen, why are you smirking? Is there anything dirty on my face?"

Her expression was very nervous, and it seemed that girls attached great importance to their appearance.

Afterwards, I found a mirror to look at it again and again.

Only after confirming that there is no dirty thing can you feel at ease.

"Ruoxue, this, can you kiss me?"

Ye Chen said softly.

"What? Kiss you? Ye Chen, are you flirting with me? If so, I have to say that your methods are too old-fashioned."

When Su Ruoxue heard this, she was not only not angry, but also despised Ye Chen over and over again.

After all, she has seen many things like being flirted with.

He also did not take Ye Chen's [earthy love words] to heart.

She ignored it directly.

When she was about to continue reading, she suddenly found that her body stood up uncontrollably.

Afterwards, she couldn't help but kiss Ye Chen's cheek.

"Ye Chen, you--"

Su Ruoxue was not stupid and immediately attributed his strangeness to Ye Chen.

When she just opened her red lips and hadn't finished speaking, her red lips were already kissing Ye Chen's face.

In a moment, Su Ruoxue's brain crashed instantly.

She didn't react.

"What? My first kiss..."

After she reacted a little, she finally realized that she had lost something very precious.

First kiss!

At this time, after she escaped from Ye Chen's control, she immediately glared at Ye Chen fiercely, ready to attack Ye Chen.
