Cataclysmic Era: I can unlock the tech tree

The images from the satellite deeply moved everyone in the command center.

Apart from a portion of the new generation born from Proxima Centauri, most of the people present were older researchers from Earth.

The scenes unfolding on Dawn Star deeply touched their hearts.

"if……"

An elderly man with gray hair trembled slightly, his eyes glistening with tears of emotion, and murmured to himself, "If only humanity had had such methods back then, so many people wouldn't have died during the escape."

His words silenced the researchers around him.

Lü Yongchang clapped his hands lightly.

The crisp applause immediately drew everyone's attention.

"Cheer up, everyone."

"The experiment was a complete success, so why the long face?"

With a faint smile, Lü Yongchang said in a teasing tone, "At this rate, once you master the technology to terraform planets, won't you be making things miserable for Earth?"

The humorous words instantly dispelled the original gloomy atmosphere.

For a moment, a cheerful atmosphere filled the air in the command center.

"Ding-dong."

A crisp reminder interrupted everyone's laughter.

Lu Yongchang's eyes flickered slightly as he turned his gaze to the holographic projection beside him.

Zero's virtual image slowly emerged.

"Professor, news has come from the biological shipboard laboratory."

Zero's synthesized voice rang out in the command center: "There has been a problem with the Magna Heart Enhancement Hormone Experiment."

"Currently, a large number of laboratory mice have died."

The relaxed smile that had just appeared on Lü Yongchang's face gradually froze.

"it is good."

"I'll be right there."

……

A series of hurried footsteps echoed in the starship's corridor.

Lu Yongchang looked grave, his brows furrowed, and hurried toward the biological shipborne laboratory.

How could this happen?

His mind was filled with confusion.

A few days ago, he even took some time to look at the experimental records in the biology lab.

The mice injected with Magna heart-strengthening hormone showed remarkably strong vital signs.

The beating force of that heart far exceeded that of a normal white mouse!

How come these mice suddenly started dying in large numbers?

Could it be a genetic issue?

Thinking of this, Lü Yongchang's expression tightened, and he quickened his pace again.

If it really is a genetic issue, then what they are about to face is probably a very difficult problem!

"clatter!"

The hurried footsteps stopped.

As the laboratory door slowly opened in front of him, Lü Yongchang took a deep breath and stepped inside again.

……

Chaos reigned inside the biological shipboard laboratory.

Almost every researcher was busy with the work at hand.

Clearly, the unexplained deaths of the mice put them under considerable stress.

"professor."

The voice of Mao Zhengzhi came from beside him.

"What's going on?" Lu Yongchang asked urgently as he walked toward the experimental table not far away.

"The autopsy is still underway, and the specific cause has not yet been discovered." Mao Zhengzhi paused, "However..."

"But what?" Lu Yongchang stopped and frowned as he looked at Mao Zhengzhi beside him. "Speak up if you have something to say, don't hold back."

Mao Zhengzhi touched the tip of his nose with a wry smile: "However, according to preliminary test results, all of these mice have some degree of internal bleeding."

"Internal bleeding?"

Lu Yongchang was stunned for a moment, then instantly realized a problem: "Is the strength of the heart muscle too high?"

Mao Zhengzhi hesitated for a moment and then nodded: "I also suspect that's the reason."

"However, the autopsy results are not yet available, and there is insufficient evidence."

Lü Yongchang nodded without saying anything and walked back toward the lab bench.

In front of the experimental table is an observation room separated by thick glass.

Inside the observation room, white mice are "confined" in specially made glass cages.

Most of the glass cages were already empty.

Needless to say, these white mice in glass cages have probably sacrificed their lives for the advancement of science.

Lu Yongchang looked at one of the white mice in a glass cage with a sullen face.

The white mouse lay quietly at the bottom of the glass cage, its mouth slightly open, breathing rapidly.

The holographic projection next to it displays the real-time physical condition of the mice.

The numbers on the indicator have a faint reddish tinge.

My heart rate is slightly fast, my blood pressure is slightly higher than normal, and my breathing rate is too high...

next moment.

Without any warning, the mouse's body stiffened, its blood pressure dropped rapidly, and its heart rate began to decrease sharply.

It only took a few seconds.

It's dead.

Under Zero's control, the robotic arm skillfully picked up the white mouse from the glass cage and began the cleanup work.

"professor!"

"The autopsy results are in!"

Mao Zhengzhi's soft exclamation interrupted Lü Yongchang's observation.

……

"Major aortic hemorrhage..."

Lu Yongchang flipped through the holographic images in front of him, raising his eyebrows slightly: "It seems the answer is already quite obvious."

He could even imagine the scene of these white mice dying.

The powerful heart muscle beats continuously, pumping streams of incredibly hot blood into the aorta.

However, under the influence of cardiac-strengthening hormones, the pumping force of these hearts significantly exceeds the aorta's tolerance limit.

The surging blood broke through the fragile aortic wall, and gushing blood gushed out of the body, quickly taking the life of the white mouse.

"That's right, it's a heart problem." Mao Zhengzhi's eyes were full of complex emotions. "The effects of Magna Heart Enhancement Hormone seem to have exceeded our expectations."

"Now that we've found the cause, the direction for our next research project is clear."

"We need to weaken the heart-strengthening hormone to make it suitable for mice."

As soon as Mao Zhengzhi finished speaking, Lü Yongchang shook his head: "Wrong."

"Think about it from a different perspective."

"This shouldn't be a problem with the mice's hearts, or Magna's heart-enhancing hormones."

"Huh?" Mao Zhengzhi looked at Lü Yongchang in astonishment.

"It's a problem with the mice's blood vessels," Lü Yongchang said softly. "Magna Heart Enhancement Hormone has shown perfect results."

"But this performance is not something the mice's bodies can currently withstand."

Mao Zhengzhi's expression turned strange.

Although this makes a lot of sense and there's nothing wrong with it.

But... it sounds like there's a weird, thuggish vibe to it.

"So..." Mao Zhengzhi cast a questioning glance.

"So," Lü Yongchang said softly, a slight smile playing on his lips, "in my opinion, this experiment not only did not fail, but it was actually a great success."

"However, we need to make a simple adjustment to the experimental sequence next."

"First, prepare all the enhancement hormones."

"Then……"

"A single injection of all hormones provides a comprehensive boost to the mice's bodies!"
