After more than ten seconds, the platform came to a solid ground at a depth of 100 meters. After Chen Shu verified the identity, the huge iron door in front of them, which was four or five meters high, was divided into three petals and slowly opened.

"Welcome to the Cutting-Edge Technology Lab"

In the brightly lit hall, an old man who was more like a soldier than a researcher greeted him with a smile.

“……”

Facing the other party's outstretched hand, Su Peng compared the belt on his hand as a restraint.

"Haha, it was my mistake. Number two"

After hearing the old man's words, Chen Shu walked up and untied Su Peng and the two girls. While moving his wrist, Su Peng looked at the old man in the white coat again.

"Presumably you are Dr. Jiang?"

"It's Me"

"Tell me, what do you want me to do to let them go."

"Don't worry, it's not just you, the girls behind you also want to know the truth about the contract trace system. But it's getting late, and you're probably tired. I'll talk about it tomorrow morning. Two, take them to find a few empty rooms. ”

"Yes!"

"By the way, your eyes are okay, right?"

"I'm gradually recovering now, and it's expected to be back to normal in about three hours!"

Hearing Chen Shu's answer to Dr. Jiang's words, Su Peng knew that he was not unaffected by the injury of the Pact Beast. But after so long, he didn't even snort, and this endurance alone should not be underestimated.

Chen Shu then led them through the hall, into a flashing metal door from the side, and then in front of a row of rooms with iron windows. A prison would be more appropriate than a guest room.

But there's nothing to find fault with in this case. I was tired enough to play in the water park all day, and I was attacked by the finishers. Almost as soon as he hit the pillow, Su Peng fell asleep.

The next day, I don't know what time it was. Su Peng only felt that his cheeks were slapped vigorously, and he opened his eyes unhappily, only to find that Chen Shu's smiling face was close in front of him.

"Yo, I slept soundly."

"Hmph"

"Get up, Dr. Jiang is still waiting to see you guys."

Under the leadership of Chen Shu, Su Peng returned to the hall again after joining the two daughters. Compared to last night, it looks even busier and greener. From time to time, soldiers in military uniforms go back and forth transporting some large containers. And Dr. Chiang is in the middle of it.

Seeing Su Peng and them coming, Dr. Jiang smiled slightly. Handing the document in his hand to the adjutant beside him, he walked over.

"How's it going, how are you staying?"

"It doesn't matter, shouldn't there be something more important?"

Hearing Su Peng's indifferent words, Dr. Jiang nodded noncommittally. With a gesture of please, he took the lead and walked forward. Facing the defenseless back, Su Peng hesitated for a moment but followed.

"About the ...... of the Trace System"

"Before that, please answer me a question."

Qin Yuyan, who had been silent, suddenly interrupted Dr. Jiang's words, her eyes full of seriousness.

"I've heard rumors that STARLab has a military background, is that true?"

"Well, I can only say that there is a certain connection. In case of need, we can get help from the military through special channels. However, this is known only to a few high-ranking generals, and your grandfather is not among them. ”

Dr. Jiang's words made Qin Yuyan's expression relax slightly. She really didn't want to believe that the old man who cared for her was also involved in such darkness.

"So, in fact, the state also knows the truth, right? And acquiesced in your killing of the people? ”

Dr. Jiang stopped and turned his head to look at Xia Muyun, who was speaking. She stared at Dr. Jiang with her fists clenched, her body still trembling slightly.

“……”

After a moment of silence, Dr. Jiang sighed deeply before moving again. A glass door opened from the side of the hall that appeared to be used as a warehouse, and motioned for the three of them to follow with Chen Shu.

"The government also wants to take a more moderate approach if possible. Unfortunately, reality does not allow us to delay any longer. There's no time left......"

"Don't have time? What do you mean? ”

"Global warming, desertification of land, extreme terrorism. The threat to humanity is imminent, and there is even definite evidence that extraterrestrial beings are monitoring Earth. In this case, the government needs to find a practical means to protect the continuation of human civilization. Hmm, how much do you know about quantum mechanics? ”

Walking in a glass passage, Dr. Jiang suddenly asked.

"I've heard of the basic theory, but I've ...... it specifically"

"It's okay, that's enough."

Stopping in front of a silver-white metal door, Dr. Jiang verified it with his ID card and retina. As the door opened, he turned to look at the three.

"What you see now is the real STARLab"

Passing through the gate, everyone was greeted by a huge spherical room with two floors. At the foremost of the ball wall is a huge map of the world, but it seems to be a little different in the subtleties. In the spherical room, the first floor is lined with neat rows of computer desks. Researchers of all colors, dressed in white lab coats, were working nervously on it, and occasionally a few men in military uniforms could be seen hurrying by. Su Peng, where they were, was on the second floor, which protruded from above. Through the huge floor-to-ceiling glass, you can clearly see the busy figures below.

"At the end of the nineteenth century, physicists thought that classical physics had reached its end. At this time, the emergence of quantum mechanics was recognized by more and more outstanding physicists. However, today, it has become the only straw for us human beings. ”

"String Theory...... Or have you heard of the parallel world theory? ”

"Hmm"

Although he was a little shocked by the scene in front of him, Su Peng nodded silently.

"The world is not made up of electrons, neutrinos and other dots, but strings. The whole three-dimensional world is like a membrane, and there are other worlds in different dimensions outside the membrane. ”

"That's right, it seems that you know a lot about physics."

"After all, college physics is also mentioned, and I read some of it beforehand."

Shrugging his shoulders, Su Peng's expression was extremely indifferent.

"What does this have to do with the Covenant System?"

Without answering him immediately, Dr. Chiang led them down to the first floor, and entered the long glass hallway through a flashing metal door on the side.

"In the face of multiple threats to humanity, the United Nations has convened some of the world's best scientists and decided to come up with a practical solution. But in the end, it was concluded that the decline of the Earth was inevitable and that the only way was to find another habitable planet. ”

"But you also know that with the technology that humans have, let alone find a planet suitable for survival. Even if you find it, it will be difficult to achieve it even if you want to immigrate in another hundred years. At this time, STARLab, which I was in charge of, made a breakthrough. ”

At the end of the hallway, the door opened again after verifying the identity information as usual, but this time the hall was obviously different from other places, and the most conspicuous thing was the closed "door" in the center. On either side of them, there were several heavily armed soldiers on alert.

Strangely, from inside the door, Su Peng seemed to faintly feel a breeze blowing out. It still smells of earth and plants.

"Open the Door"

After giving orders to the surrounding researchers, Dr. Jiang turned to look at them again.

"My research direction is parallel world theory, which is derived from string theory. Rather than chasing that ethereal hope in the vast sea of stars, it is more realistic to break that membrane and go to another earth. And I did succeed, but at the same time I failed. ”

"The moment they opened the passage and discovered another Earth, all the researchers stood up and celebrated. The earth was as perfect as we imagined, full of unexplored and pristine lands, full of life. After several machine explorations to determine that the atmosphere was similar, I actually set foot on the land under the protection of the military. And in front of us is the gate we passed through at that time. ”

Airplanes......

A hurried alarm sounded, and a bunch of well-armed soldiers came running from the side. There were even two machine guns and rocket launchers brought out. All of them grimaced their guns and pointed their guns at the door in the center of the room.

At this moment, the door slowly opened. When he saw the scene on the other side of the door, Su Peng was stunned for a moment. And Qin Yuyan lowered his head thoughtfully.

"Another Earth...... Why?"

"That's right, it's another Earth. Let's go, I'm sure you'll be familiar with it. ”

After Dr. Jiang finished speaking, he stepped into the door first, and Su Peng and the others also entered the gate under the "escort" of a large number of soldiers behind them. In an instant, you went from the cool underground to the rainforest.

That's right, on the opposite side of the door. It's a forest in the morning mist.
