Cataclysmic Era: I can unlock the tech tree

Dawn Star.

Amidst the swirling yellow sand, two planetary landers struggled to move forward.

Inside the planetary landing vehicle.

Current wind speed: 50 km/h!

Accompanied by flashing bright red holographic text, alarms sounded continuously.

"drop!"

"Abnormal wind speed warning!"

"Please proceed to the nearest safe haven immediately!"

Xia Wanyi gripped the steering wheel tightly, her eyes filled with anxiety: "Joey!"

"How far is the nearest safe haven?!"

Joey's voice came from the back seat: "0.83 kilometers!"

"0.83 kilometers, at the current speed..." Xia Wanyi muttered to herself, her anxiety growing.

"Let me see," Hong Fan's voice came from the passenger seat, interrupting their conversation.

A short rest, coupled with various energy-replenishing foods, allowed Hong Fan, who had been lying there like a corpse, to regain some of his energy.

He struggled to sit up and reached out to manipulate the holographic image on the control panel in front of him.

The holographic map quickly appeared in front of him.

Before Hong Fan could speak, Fang Xu's voice came through the long-range communication device again.

"This is the Earth, and we are now broadcasting our first message to the entire ship."

Fang Xu's voice was extremely solemn: "According to the latest observations and research results, a global storm is brewing on the surface of Dawn Star."

"Specific data has been transmitted to the personal terminal."

"All squads, immediately locate the nearest shelter."

"I repeat, all squads, immediately locate the nearest safe haven and await fleet rescue!"

Communication was cut off.

The crackling sound of gravel hitting the car windows, along with the roar of the engine, filled everyone's ears.

"What do we do now?" Xia Wanyi's voice broke the deathly silence in the cabin.

Hong Fan frowned, reached out and opened the latest transferred file, and began to read it carefully.

A chain reaction triggered by A2 and A1 plains storms, resulting in a global storm with expected maximum wind speeds exceeding 70 km/h...

The ever-increasing predicted wind speed cast a shadow over Hong Fan's mind.

He knew they had to find a completely safe haven immediately.

Otherwise, those located in the epicenter of the global storm would face certain death!

He glanced at the holographic map beside him.

On the map, a huge marker is flashing red.

That's the exit of the canyon, which is the A1 plain area.

In Joey's plan, they could use this huge "mound" that stretches across the A1 and A2 plains to withstand the hurricane.

but now……

Let alone whether we can safely reach the A1 plain.

In the face of a global storm, the originally chosen safe haven becomes a joke!

A glint of light flashed in Hong Fan's eyes.

He turned his gaze to the severely weathered stone wall beside him.

"Turn around!" Hong Fan said decisively.

"What?!"

Xia Wanyi was stunned for a moment, then looked at Hong Fan beside her in surprise.

She began to wonder if there was something wrong with her ears.

"I said, turn around." Hong Fan took a deep breath. "Activate all weapons."

"Dig a hole in the rock face!"

Xia Wanyi turned her head to look at the yellow and silver-white stone wall beside her.

After a brief moment of thought, she stepped on the brake and slowly turned the car around.

A violent tremor came from the chassis.

"This car can only withstand crosswinds up to 50 km/h!" Xia Wanyi suddenly shouted.

Hong Fan glanced at the wind speed on the holographic projection.

52km/h.

"45° diagonally to the right and forward!"

The situation was critical, and Hong Fan roared, "Bruno, you take control of the weapons systems! Fire everything you can, except for the miniature nuclear bombs!"

Under Xia Wanyi's control, the planetary lander came to a difficult stop in place.

Then, the vehicle-mounted laser cannon and the vehicle-mounted electromagnetic cannon simultaneously blasted towards the stone wall in front!

After coming to a stop, the second planetary landing vehicle also activated its onboard weapon system and joined the "digging" operation.

In an instant, countless grains of sand and iron filings were scattered and flew about in the wind!

The stone wall, with its extremely weathered surface, naturally could not withstand the bombardment of a level-two civilization weapon.

Even though these weapons are all vehicle-mounted, stripped-down versions, their power has been greatly reduced.

In less than a minute, a huge crater appeared in front of everyone.

Thanks to the storm, most of the rocks and iron ore fragments were blown into the air, leaving only some large stones and iron blocks inside the cave.

Hong Fan didn't hesitate at all: "Let's go!"

"Let's go inside the cave!"

Xia Wanyi naturally stepped on the gas without hesitation.

With a roar of its engine, the planetary lander, thanks to its powerful off-road capabilities, plunged into the dark cave.

……

【Earth】.

Biological laboratory.

Immersed in his experiments, Lü Yongchang was naturally unaware of what was happening in the outside world.

Fang Xu had not yet asked for help, and Ling was still carrying out Lü Yongchang's orders: do not disturb his research work as much as possible.

"Professor," a researcher excitedly ran to Lü Yongchang's side and whispered, "the corresponding hormones have been successfully isolated and purified."

"The lab mice are ready."

"We can begin the first experiment at any time!"

Lu Yongchang's eyes suddenly lit up, and he quickly stood up from his chair: "What are you waiting for?"

"Begin the experiment immediately!"

……

It's still the familiar controlled experiment.

However, in order to eliminate the influence of individual differences among mice on the experimental results, this experiment adopted a self-control method.

It's easy to understand.

A self-control means comparing the data of each animal before and after the experimental treatment.

Lü Yongchang followed the researcher and quickly walked towards the experimental area specially designated in the biological laboratory.

Hundreds of mice were kept individually in specially made glass cages.

Inside each glass cage is a robotic arm.

Feeding, experimentation, carcass disposal, disinfection... every step is personally controlled by Zero to ensure that no unexpected situations occur.

For example, viral or bacterial infections.

These are the things that must be noted when conducting biological experiments inside the Earth.

Lü Yongchang didn't want the entire crew to contract some deadly disease for the sake of a biological experiment.

After ensuring that all test data were accurate, Lü Yongchang gave the order to start the experiment!

Mechanical arms reached out and grabbed at the white mice inside the glass cage.

Perhaps sensing the approaching danger, the mice began to scatter and flee throughout the cage.

But clearly, all of this was in vain in the face of zero capture efforts.

The next moment, a thin needle popped out from the robotic hand and precisely inserted into the vein of each mouse.

Hormone injection.
