Cataclysmic Era: I can unlock the tech tree

"Freeman was born from Proxima Centauri b."

Mao Zhengzhi's voice came from the side: "He's the mastermind behind that incident."

"Your physical fitness is quite good; you completed all the enhancement programs so quickly."

Lu Yongchang raised an eyebrow and asked somewhat casually, "What are the next steps for the test?"

Will he cooperate with this experiment?

Mao Zhengzhi remained silent for a moment, then nodded.

"I believe he will cooperate."

"Before the experiment, I told them that if the experiment was successful, they would be released without charge."

"Although this statement is not very credible, and they probably don't really believe it, any life would strive to pursue the only way out."

"It's an instinct etched into our genes; there's no escaping it."

Lu Yongchang didn't speak, but turned his head to look at the holographic screen in front of him.

The gravity chamber slowly rotated.

Equivalent gravity: 0.5g.

In the video, the man named Freeman lies motionless in the gravity chamber with his eyes closed.

For this experiment, Mao Zhengzhi even asked Zero to specially make a gravity chamber.

Similar to the gravity chambers used in laboratory animals, this gravity chamber can achieve an effective gravity of up to 7g.

Unlike the large gravity chambers on starships, this gravity chamber has a small interior space due to material limitations, accommodating only one person at a time, and it doesn't have many facilities inside.

Judging from his appearance alone, you would never guess that he was a criminal who had committed heinous crimes against humanity.

"He was injected with a large amount of sedatives," Mao Zhengzhi explained from the side. "After the enhancement, his physical condition was much better than before, and this was done to prevent any unexpected situations."

Lü Yongchang nodded in understanding.

Indeed, for this group of researchers in the laboratory who were powerless to do anything, Freeman, who had completed all the enhancement work, was undoubtedly a dangerous presence.

Although there is the protection of Zero-Sum Robots, if any accident were to occur, it would be unacceptable to both Lü Yongchang and Mao Zhengzhi.

"Prepare to begin the experiment. All units, please take note."

Mao Zhengzhi turned on the microphone and gave the order in a deep voice: "Prepare to wake up the experimental subjects."

As soon as he finished speaking, a silver-white mechanical hand slowly reached out towards Freeman.

The needle was precisely inserted into his vein.

A few minutes later.

Freeman struggled to open his eyes.

He didn't get up immediately, but instead looked around at the completely unfamiliar surroundings.

The next moment, as if sensing the presence of gravity, he gently raised his hand and tested it.

After several checks, his muscles tensed as he tried to stand up from the ground.

"Bang!"

A loud bang was transmitted into the biology lab via microphone.

That was the sound of Freeman hitting the "ceiling" of the gravity chamber.

"hiss……"

The impact was clearly severe; Freeman grimaced and rubbed his shoulder, carefully managing to return to the "ground."

"Record it." Mao Zhengzhi looked seriously at the image on the holographic projection. "Your body control has decreased significantly."

Then, he reached for the microphone next to him and turned it on.

The moment the voice came out, Freeman's expression changed drastically!

"Mao Zhengzhi!" Freeman, as if facing a formidable enemy, tensed up and stared at the camera beside him, shouting, "What did you do to me?!"

"You forgot?" Mao Zhengzhi raised an eyebrow and continued to ask.

"..."

Freeman paused for a moment, then looked down at his own body.

Perhaps he was shocked by the well-defined muscles on his body, his face was filled with a very complex expression.

Shock, doubt, confusion, worry...

After a long while, his tense body relaxed somewhat: "This is the human enhancement experiment you were talking about?"

As he spoke, he clenched his fist: "Feels good, definitely much stronger than before."

"Record: Conscious and with good memory," Mao Zhengzhi said, turning to the researchers beside him.

"Hey!" Freeman had clearly heard Mao Zhengzhi's words, and he snapped somewhat impatiently, "What exactly do you want me to do?"

"Don't forget what you told me back then: if I completed this experiment, I would be able to..."

"Acquittal." Mao Zhengzhi interrupted Freeman. "Of course I remember, provided you cooperate with our upcoming tests."

How can I trust you?

Knowing he had completed the body enhancement experiment, Freeman's lips curled up slightly, and he sat down on the ground without any hurry to ask a question.

"Watch your attitude! You have no right to negotiate with us!"

Mao Zhengzhi frowned and shouted sternly!

Freeman pursed his lips, clearly not taking Mao Zhengzhi's reprimand to heart.

He surveyed his surroundings again: "Where are my companions?"

"They haven't completed their human enhancement experiments yet?"

Mao Zhengzhi did not speak.

Freeman, having gleaned the answer from the silence, smiled again: "So, I'm now the only test subject who has completed human enhancement?"

"Don't you have any alternatives besides me?"

Mao Zhengzhi frowned even more deeply.

This scene was somewhat beyond his expectations.

"Of course there are other options." Lü Yongchang reached out and took the microphone from Mao Zhengzhi, and said in a deep voice, "Besides you, two other people have completed human enhancement experiments."

You now have two options.

"One option is to be ejected from the starship and become space junk."

"Second, follow our orders and complete all tests."

A flicker of surprise crossed Freeman's face: "Who are you?"

Where is Mao Zhengzhi?

"After completing the test, will I be released without charge?"

"Can you keep your word?"

Lu Yongchang's tone grew increasingly stern: "Correct your attitude. You just need to tell me your choice."

silence.

In the video, Freeman falls silent.

From his furrowed brow, Lü Yongchang could tell that he was constantly considering the situation outside.

"Ten seconds." Without any hesitation, Lü Yongchang shouted again, "Tell me your choice."

"Zero, get ready. If there's no response in ten seconds, throw him out of the Earth."

"Received." Zero's synthesized voice echoed throughout the laboratory and gravity chamber: "Nine, eight, seven..."

"Wait! You're Lü Yongchang?!" Freeman suddenly realized something, his eyes widened, and he shouted loudly.

"Three, two..."

The only response he received was a cold countdown from zero.

"Two! I choose two!"

Freeman's eyes widened in terror as he watched the silvery mechanical hand reach for him, and he shouted.

The robotic arm stopped just ten centimeters away from him.
