Leaving the mission hall, the three members of the second class parted ways.

Chen Yu returned to the dormitory.

Duan Ye followed Bahuang Yao to get the elixir.

Entering his room, Chen Yu washed his face, tightened the curtains, then took out a grade A synthetic fluid from under the bed and took half a syringe.

When a mandatory mission came, he no longer had time to act steadily, so he could only be more aggressive.

[Infected by unknown liquid: Jinqi +16033]

【Energy +15772】

【Energy +15805】

【Energy...】

"Um?"

Half a tube of grease was submerged into the body, Chen Yu frowned slightly: "It seems that there is no breakthrough..."

Try to activate your energy.

Sure enough, the strength level is still at level 1.9.

After hesitating for a moment, he took out another half tube of synthetic fluid and slowly pushed it into the vein.

[Infected by unknown liquid: Strength +15628]

【Energy...】

Putting down the needle and standing up, Chen Yu activated the sea of ​​qi again.

"boom!"

The raging wind blew.

But the level of strength has still not reached level 2.

"It's a whole tube of synthetic fluid, it should be fine..."

"Is there any bottleneck here?"

After thinking about this, he first covered the synthetic liquid, then picked up his phone and searched on Baidu.

Soon, something was gained.

It turns out that after levels like 1.9, 2.9, and 3.9, there really is something like a "bottleneck".

That is a kind of "deep processing of Qi Hai."

For example, before level 2, the air sea condensed in the form of mist.

If you want to go further, you can only compress the sea of ​​​​qi, compress it to a liquid state, and make room for the Dantian, so that you can "accumulate" more energy.

After successful compression, you can advance to level 2.

The same is true before level 3.

The liquid "liquid sea" must be compressed into a solid state in order to successfully reach level 3.

The ranking of human energy levels is also based on this point.

From this point alone, Chen Yu immediately deduced a fact.

The further you get to later levels, the greater the difference in strength!

Because after each compression, the difference in the total amount of energy will increase exponentially.

For example, the amount of energy at level 1.9 is 90, then the amount of energy at level 2 is 100, but as the sea of ​​​​qi is compressed into a liquid state, the amount of energy at level 2.1 may reach 200...

And so on.

At level 2.9, the energy amount is 900, and at level 3, the energy amount is 1000. Then the energy amount at level 3.1 reaches 2000.

Level 3.9 is 9000, level 4 is 10000, level 4.1 is 20000...

Therefore, when facing an enemy, if you are level 1.9 and the opponent is level 2.0, don't be afraid, both sides are capable of fighting.

After all, the difference between the two is only one sea of ​​compressed air.

But when you encounter a level 2.1 warrior, the opponent's strength may be twice that of level 1.9, making it impossible to fight. You can run as fast as you can...

This is still an order of magnitude below level 4. The difference is not outrageous.

When you reach level 4 or above, the total amount of energy between each 0.1 level will be terrifying.

"If this is the rule..." Chen Yu said thoughtfully: "The importance of one genius is more important than hundreds or thousands of warriors combined."

Five level 3 warriors can work together to kill a level 4 warrior.

But a hundred level 7 warriors will never be able to defeat one level 8 warrior.

And facing level 8.1, no matter how many level 8 warriors there are, it won't help.

Level 8.2, and can beat 8.1 with blood...

"What the hell."

Chen Yu was a little confused: "Weird combat power system, every scale is too different..."

He lowered his head and looked at the two cans of Grade A synthetic fluid on the bed. He hesitated.

I originally thought that after eating these two cans, I would be able to break through to level 3 at least.

But now it seems that it would be good to increase it to 2.5.

"So how big is the talent gap between my body and Duan Ye, Bahuang Yao and the others?"

This is no longer a matter of waiting.

This is three hundred and sixty-nine!

If his previous crane tail physique was hovering around the "30th level", then Duan Ye and Bahuang Yao would be around the "300th level".

As for Bahuang Yi?

Maybe we have to wait until "3000"...

"It seems like it's easy to save humanity."

Chen Yu's thinking expanded: "If the highest-level alien beast in the beast tide is a level 9, then as long as a level 9.1 genius appears, the entire beast tide can be suppressed."

"All mankind has been waiting for the appearance of '9.1'..."

"And that person... people seem to have been waiting for it."

Turning his head, he looked at the Spirit-enhancing Pill presented by Bahuang Yi on the table.

A curry-like smile appeared at the corner of Chen Yu's mouth: "This is just a joke..."

"Yeah, reasonable."

Nodding, Chen Yu recovered his thoughts and continued to slide the screen of his mobile phone, looking for a way to compress the air sea.

However, after searching for half an hour, I found nothing.

This knowledge of promotion seems to be blocked.

There is no publicly available free information online.

After pondering for a moment, he exited the browser, clicked on WeChat, and typed a question in the Class 2 WeChat group.

[Chen Yu: Is anyone here? 】

【Bahuang Yao: I am here.】

[Chen Yu: Where is Duan Ye?]

[Bahuang Yao: He lost his cell phone.]

【Chen Yu: Great.】

[Group member "Duan Ye" was kicked out of the group by the group leader "Chen Yu"]

[Chen Yu: Okay, let him go. I have something to ask you. 】

【Bahuang Yao: Brother Yu, tell me.】

[Chen Yu: To advance, you need to compress the sea of ​​air. How do you operate this kind of thing? Do you know how to do it? 】

[Bahuang Yao: I can. But this is very complicated to talk about. Brother Yu, go find a professor to take a paid class tomorrow. He can plan a targeted compression method for you. 】

[Chen Yu: OK, then sign up for a class for me, preferably in the morning, so as not to waste time. Do we have enough credits left? 】

[Bahuang Yao: There are still more than 20 credits left. It is enough to pay for this basic paid course. 】

[Chen Yu: Okay, thank you Yao Yao, withdraw. 】

【Bahuang Yao: Brother Yu.】

[Chen Yu: What?]

The chat interface was quiet for a while.
