A few months passed, and the reading room, which used to be quite lively, became much quieter, with only a few students reading.

Just as Chen Chu walked out of the elevator, the girl at the window in the distance looked up slightly, as if she had sensed something, and a smile appeared in her eyes after seeing him.

Chen Chu couldn't help but smile and sat down opposite her.

Today, Luo Fei is wearing a pink patterned short-sleeved T-shirt and slim-fit jeans, looking neat and tidy.

The long black hair is still tied with a white butterfly at the back of the head. The hanging white ribbon is intertwined with the long hair, giving a fresh and beautiful feeling.

Although they hadn't seen each other for more than two months, they didn't feel strange at all. After sitting down, Chen Chu asked curiously, "Luo Fei, what have you been doing in the two months since you came back?"

The girl smiled and raised the book in her hand: "Reading. Recently I have read all the thirty-six Taoist scriptures and the thirteen Taoist scriptures."

"In addition, there are the thirteen Buddhist sutras and seventy-two volumes of Mahayana. Although many of the contents are profound and difficult to understand, I have gained a lot from them."

"Awesome." Chen Chu praised slightly.

Because half of his consciousness was caused by the long-term killing of strange beasts, Chen Chu's brutal and destructive desire became stronger and stronger, so he also thought about using these scriptures to cleanse his soul.

But unfortunately he couldn't read it, or couldn't understand it, these abstruse scriptures.

Until later he went to the battlefield of strange beasts, fought a bloody battle all night under the blood moon, and finally swept across the battlefield to gather his fighting spirit, and cut off the extreme desire for killing and destruction in his heart.

Yes, in Chen Chu's understanding, the bloody fighting spirit of the prison was actually the killing intent that he slashed out.

At this time, Chen Chu was a little puzzled and said: "Strange, although I can't sense your specific realm, Luo Fei, you should not have broken through the fourth level, right?"

Luo Fei’s practice method has always been different from others. Just by reading Taoist and Buddhist scriptures, she can enter the ethereal state. Under this special state, her practice speed is very fast.

At the beginning, her aptitude was similar to Chen Chu's, and both of them established their foundation within half a month.

But as he practiced that special technique and read the book every day, his practice speed gradually surpassed geniuses like Xia Youhui and was no less than that of Lin Xue and others.

When she left the alien beast battlefield more than two months ago, her cultivation was already in the late third level. Logically, she should have broken through to the fourth level long ago.

Facing Chen Chu's doubts, the girl blinked her eyes and said, "Not yet. I seem to have hit a bottleneck recently and have been stuck at the peak of the third heaven."

"But I feel like I'm about to break through." Just as she finished speaking, a powerful aura that could no longer be suppressed burst out from the girl's body.

boom!

The energy of heaven and earth within a radius of hundreds of meters around was rioting and swarming towards Luo Fei, transforming into an invisible gust of wind that surrounded her and made Chen Chu's hair fly.

The sudden change attracted the attention of many people. In Building C, many martial arts students subconsciously looked up at the ceiling with envy in their eyes.

"Such a strong aura."

"Someone is breaking through to the third level. No, it should be the fourth level. The aura of the third level is not that strong."

"Which genius is making a breakthrough?"

"Don't be a genius. Our first-year genius has already broken through to the third level and entered the alien beast battlefield. The person who may break through now should be Luo Fei from Class 3."

"Didn't Luo Fei from Class 3 say that she couldn't stand the high-pressure environment of the alien beast battlefield and came out after only one month?"

"You believe this kind of thing?"

"Brother, you underestimate Luo Fei. During the cleanup mission at the beginning of the year, she followed that monster Chen Chu deep into the mountains every day and hunted many mutant beasts."

"And in the last level 4 mission, she killed the dragon-armored beast with dragon blood with one shot. Do you think she can't stand the high-pressure environment of the alien beast battlefield?"

"So she came out of the alien beast battlefield for another reason?"

"Nonsense, for sure."

While many students downstairs were envious and talking about this, in the reading room, as the true power began to change qualitatively, the aura emanating from Luo Fei became increasingly powerful.

However, compared to the heavy and overwhelming feeling when Chen Chu broke through the fourth level, Luo Fei's breakthrough gave people a light, ethereal and vague feeling.

Although the person was right in front of him, Chen Chu had a feeling that she was standing outside the world, extremely far away from him.

He had felt this strange feeling once a few months ago and thought it was an illusion at the time, but now it seems that it should be the attribute of Luo Fei's martial arts.

Whoosh!!

Surrounded by strong winds and rich energy from heaven and earth, the girl's aura continued to rise. In just a moment, she completed a qualitative change in her true strength and entered the fourth level.

But it didn’t stop here.

Luo Fei's aura was still rising, and more and more energy from heaven and earth was being drawn up, and then she absorbed it quickly as if it didn't need to be refined.

Even Chen Chu was a little surprised by such a fast transformation speed, as if the energy of heaven and earth itself was her true power.

boom!

Under Chen Chu's astonished gaze, Luo Fei's aura surged and entered the middle stage of the fourth level. Only then did the energy of heaven and earth surrounding her slowly dissipate.

What followed was more than half an hour of waiting.

Not until the true power completely subsided did the girl opposite slowly open her eyes, and her bright pupils turned azure, like a cloudless sky.

The artistic conception is profound, leisurely, and has an indifference that overlooks all living things, without a trace of emotion.

But soon the girl blinked, and the cold and emotionless feeling disappeared, and her sky-blue eyes revealed smartness and smile.

But Chen Chu's expression was somewhat solemn. He looked at her and said slowly: "Luo Fei, have you been suppressing your realm before?"

The girl nodded slightly: "Yes."

"Why?"

Luo Fei said softly: "Because I will leave after the breakthrough."

Chen Chu paused: "...Return to Simon?"

"Yes." The girl nodded.

Well, he thought there was some conspiracy, but it turned out that he just didn't want to go back to Simon so soon. As for why the other party kept suppressing his realm...

Without waiting for Chen Chu to think about it, the girl changed the subject: "Chen Chu, remember what I said at the beginning, that I can equip myself with real weapons after I break through the fourth level."

"Remember."

Once when Chen Chu broke through the fourth level, the girl said that her sniper cannon was only a weapon before the fourth level, and that her strength would have a leap after she broke through the fourth level.

By then, weaknesses such as insufficient power of martial arts and inability to fight in close combat will no longer be a problem.

Luo Fei's eyes moved with a smile: "How about it, Chen Chu, do you want to see the divine machine weapon that my aunt prepared for me?"

…

In the northern suburbs of the city, Chen Chu followed Luo Fei to the vast research base again.

It was still a strict identity verification process, including for Luo Fei, who came frequently, who had her pupils, fingerprints, and mental fluctuations tested, and was only allowed to pass after being confirmed to be correct.

However, the last time Chen Chu registered and verified his identity, it was a second lieutenant, but this time the identity displayed on the computer in the guard room was? ? ? Three question marks.

At the same time, after the question mark, note that you have no right to query.

The two guards immediately looked serious and did not stop him, because this meant that the other party's identity level and confidentiality were very high and they were not qualified to know.

Only after Chen Chu entered did the two guards send the information to the central building of the research base.

The two quickly passed through the research buildings and came to the central research building that was more than 100 meters high, but they didn't see anyone inside.

As soon as he stepped into the building, Chen Chu felt more than a dozen 'gazes' and some invisible rays of light sweeping over him.

The security here is even tighter.

Standing at the door, Luo Fei shouted: "Auntie, I have broken through the fourth level."

A calm female voice came from the side wall: "I'm in Laboratory 03 on the 15th floor. I have a research project on hand. Come up first."

As he spoke, the invisible sense of surveillance around him disappeared.

Luo Fei turned around and explained: "Let's go, those dead-line weapons have been shut down. This is my aunt's core research institute, and the defense is very strict."

“Without her consent, even high-level practitioners cannot go up. They will be seriously injured or even killed by the dead-line weapons scattered in every corner and on the outer wall.”

"Deadline weapon." Chen Chu was a little surprised.

After reaching the seventh level, practitioners' movement speed can exceed one or two times the speed of sound. Ordinary missiles cannot explode the protective flames and they can ignore most heavy weapons.

And this death ray can actually threaten even practitioners at the seventh or eighth level.

"It is a weapon that contains death energy rays. Its core is a level nine giant beast crystallized death eye. It has extremely high penetration and disintegration properties against extraordinary energy."

"Once this kind of ray penetrates the body's protective true energy, the body of a high-level practitioner will rot and be injured."

Well, a modified technological weapon.

As they were talking, the two took the elevator to the fifteenth floor.

This floor is full of laboratories, filled with various instruments that Chen Chu is unfamiliar with. In the distance, a woman in a white coat is standing in front of a piece of equipment.

At this time, the energy device was running at full power, shooting out countless tiny purple light beams up and down, hitting a piece of metal, emitting circles of light.

Luo Fei and Chen Chu stood in the distance and did not go over to disturb each other.

But before the two of them had to wait long, the piece of metal suddenly emitted a dazzling light, and powerful and unstable energy fluctuations emanated from within.

Boom! The metal explosion shook the equipment continuously, but the impact of the explosion was blocked by a layer of transparent glass.

Luo Wu Yue looked at the data flashing on the monitor and frowned slightly: "The limit of the micro-inscriptions inside the tear gold is only 173 layers."

At this time, Luo Fei walked over and introduced with a smile: "Aunt, this is the Chen Chu I told you about."

Chen Chu said politely: "General Luo."

Even Chen Chu admired this legendary woman from Dongxia who had no talent for cultivation but was awarded the rank of general for her outstanding contributions to military technology.

Luo Wu Yue looked at Chen Chu, nodded to him, and said in the calm tone unique to researchers: "I have read your information, it is very good."

"In addition to nine months of foundation building and cultivation in the seventh heaven, I created my own secret book and killed the Blood God's clone in the early eighth heaven with my cultivation in the late sixth heaven."

“These achievements would have been amazing even in the glory days of decades ago.”

Being praised in person like this, even Chen Chu felt a little embarrassed and coughed dryly: "General Luo, thank you for the compliment. My achievements are also paved by the predecessors."

After greeting her, Luo Wu Yue looked at Luo Fei and said calmly, "Since you have already broken through the fourth level, go and refine that set of weapons."

Led by Luo Wu Yue, the three took the elevator to a depth of one hundred meters below the base. As the heavy metal door opened, a humanoid mecha appeared in front of the three.

The mecha is only four meters tall, mainly white and gold, with some blue embellishments. There are wing-like modules behind the shoulders, and the overall appearance is very delicate and gorgeous.

And on the shelf behind the mecha are some giant weapons and equipment.

For example, there is a sniper cannon with a seven-meter-long barrel, a six-meter-long silver sword, and several sci-fi weapon modules similar to missile launchers and energy cannons.

But that armed object is more like a larger set of armor than a mecha. After all, how can it be considered a mecha if it’s not even ten meters tall?

Shouldn't a standard mecha be a giant weapon that starts at fifty meters and has no upper limit of one hundred meters?

When Luo Fei went to the next room to change clothes, Luo Wu Yue calmly introduced: "This is the man-machine integrated divine weapon I designed for Xiao Fei."

"The main materials are all from mutant behemoths. The rune sequence chain forms a functional circuit inside. The core is an energy-based eternal power furnace."

"This weapon is actually a set of extraordinary weapons that integrates high technology. It is divided into multiple templates, firepower systems, auxiliary training, flight, etc."

"In addition to the core humanoid body, multiple matching external weapon templates can be loaded to achieve single-soldier suppression or firepower coverage."

While Luo Wu Yue was introducing, the door of the dressing room next door opened, and a heroic girl wearing a silver driving tights came out.

Chen Chu couldn't help but be amazed.

There’s no way, the girl in the driving suit has a pretty figure…

Luo Wu Yue said calmly: "Xiao Fei, activate the weapons first and complete the initial refining."

"Yeah." The girl came behind the platinum-colored mecha with some anticipation, jumped slightly and stood on the "wings", pressing her palm on the back of the mecha's neck.

"Ding! Fingerprint test passed."

"The mental fluctuations match."

"Biological genetic testing is consistent."
