"I have an offer."

Everyone looked at each other, and after a few seconds, Tony Stark suddenly spoke.

"Assuming this Pym particle really has such a miraculous effect, why don't we build a particle collider and try it."

"As long as it's big enough, it should be okay to measure the reaction."

"That's right."

As soon as he said this, Dr. Pym's eyes lit up slightly.

He simply didn't have the conditions to do those super-large and sophisticated studies to analyze why the Pym particles failed, but he had tried to experiment with all the means available, but to no avail.

Tony Stark said this today, which made him suddenly wake up, yes, it is not the era of Ultron's world domination, humanity has taken back the ground, although they are in ruins, but they now have nanomechanical technology, and it is not impossible to rebuild a sufficiently advanced and huge experimental collider.

"And through my research on the mother box in the past few days, I found that some of the technical content may be able to support the construction of a super particle accelerator, theoretically, as long as the equipment and energy are properly prepared, and then a little research and adjustment, maybe we can build a new generation of tachyon collider."

Tony Stark made an explosive gesture and spoke.

“... Tony, is it dangerous? ”

When Sam the Falcon saw him like this, he always felt a little uneasy in his heart.

Tony Stark is talented, but the Ultron he did before still left too much shadow for others, although it has been later confirmed that Ultron dropped the bag halfway, but in the end, the origin of these terrible robots comes from Tony Stark.

"Sam, nothing in science is 100% safe."

At this point, it was Dr. Bruce Banner who interjected.

"But it is undeniable that if the Tachyon Collider can be built, something that previously existed only in fantasy, it must be epoch-making. It will have an incomparably important impact on our physics and other related disciplines, no, it should be said that the entire civilization. ”

“... Tony, good idea. ”

Chen Sheng's face showed a thoughtful expression, and he spoke.

"I'm giving you and Dr. Pym, and Dr. Banner's motherbox, the highest level of authority, even if it's to form a collider research group, and you can recruit the remaining supplementary members yourself, and I can give you more support if necessary."

He glanced at the three people present.

"Is it possible to complete the construction of the Tachyon Collider and further research on the Pym particles in the shortest possible time?"

"I'm fine, I'm honored to be part of such a study."

Dr. Bruce Banner nodded.

"That's what I was supposed to do."

Dr. Pym nodded slowly.

"Then you are leaving our universe, how can I contact you here?"

Stark asked.

"Dr. Strange has learned the techniques of the Mystical Archive on how to open the doors to the multiverse, but he lacks some stable enough energy to safely perform them."

Chen Sheng looked at Strange who was not far away.

The light in his hand flashed, and an irregular transparent gemstone the size of a thumb cap appeared in his palm.

"This is some of the spatial energy that I have separated. It is enough to support the opening of the door to the multiverse. I left a consciousness in it that would lead the door openers to my world. Of course, I don't recommend opening the door casually if it's not necessary, because I have the power of the infinite primordial to protect it, and you don't, so there is still a certain danger. ”

After a pause, Chen Sheng continued.

"And after I leave, I will also record the current space-time coordinates, because it involves different time flow rates in the universe, so I may come back once a year and a half at the longest, and it may only be a matter of one or two months at the shortest."

"Don't worry, Master Chen, we will protect our own world, and I hope that no matter what challenges we face in the future, we will be able to fight side by side."

Steve spoke calmly at this time.

"Hmm."

Chen Sheng smiled and said.

"So be it."

In fact, before talking to everyone, he thought about it again and again, but still kept some things that he did not tell the Avengers present, such as the Mystery of Creation and Destruction of the Celestials, such as the mysterious man in the tributary of time who had the Infinity Gauntlet and several Infinity Stones.

Talking too much is a kind of pressure.

Now that the human civilization and the earth in this world have just breathed from the shadow of Ultron, he hopes that everyone can focus on the current matter, step by step, he can't ask too much, that may be too harsh for Steve, including himself.

Thinking about this, Chen Sheng didn't say anything more.

In the remaining time, he also released those alien scientists, and gave Stark and others the knowledge of the interstellar lingua franca with the ability of telekinesis, and asked Natasha to arrange their residences and work areas and other detailed work.

Finally, in the open space outside, he released the earthling man who 'wandered the starry sky', Captain Marvel Carol.

The latter is also a temperamental person, as Chen Sheng expected, as soon as Carol Danvers was released, he had the idea of wantonly demolishing the house and destroying it, but naturally he was suppressed by Chen Sheng in an instant.

After a simple explanation to her, and the people on the earth also interjected a lot, the other party gradually understood that he had returned to the earth.

And after hearing about what has happened to human civilization over the years, Carol Danvers was even a little incredulous, in this case, she automatically turned off the idea of continuing to entangle with Chen Sheng.

Chen Sheng could even feel the self-blame and guilt that welled up in the other party's heart after learning all this.

She hadn't been back for too long.

And at the beginning, she actually left an insurance policy on Earth, which pointed to the former director of S.H.I.E.L.D., Nick Fury, and the two had been familiar friends with each other for decades.

Before she left Earth, she had left an emergency star field communicator for Nick Fury, but I don't know what the reason was, and Nick Fury didn't have time to use it until he died.

Naturally, Carol Danvers has no idea what has happened on Earth in the past decade.

Soon, the time came a day later.

Chen Sheng has already arranged, instructed, and communicated, all of which are in place.

The rest also needs to rely on the efforts of this nascent human civilization itself.

Standing on the top of the rooftop of the base's high-rise building, Chen Sheng and all the Avengers gathered together again.

Or those who are familiar, Carol is among them, and after a night of thinking, she decides to stay on Earth for the time being, for the reconstruction of her hometown.

Everyone looked at the black-haired and black-eyed young man in front of them, who was wearing a pale golden robe that was not stained with dust, just as they had just met.
