Cataclysmic Era: I can unlock the tech tree

Laboratory One.

Lü Yongchang and a group of researchers stood in front of the huge holographic projection, quietly watching the constantly changing charts and data.

In the scene on the side.

Under Zero's control, several robots have entered the isolation room in an orderly manner to begin cleanup work—the shield generation units destroyed by the electromagnetic cannon projectiles need to be cleared.

"Let's organize the data and prepare to begin the next study."

Lu Yongchang withdrew his gaze, a hint of excitement in his eyes, and gave the order.

According to the research plan, after the experiment with a single shield generation unit is successful, they need to study how to make multiple shield generation units work together.

Although the Lator civilization's warships had readily available algorithms, the two civilizations' warships were constructed completely differently, so simply copying them was obviously inappropriate.

Faced with Lü Yongchang's orders, Cao Liangcai naturally agreed and turned to process the various data generated during the experiment.

In the original plan, Lü Yongchang would definitely be involved in such an important task as organizing experimental data!

But at the very moment the experiment succeeded, he sensed something strange coming from deep within his mind!

This familiar feeling...

The technology tree has been upgraded!

Thinking about the various new technologies of the third-level civilization, Lü Yongchang couldn't contain his excitement.

So he took a deep breath, suppressed his excitement, and said in as calm a tone as possible, "I'm going to rest for a while. If there are any problems, have Zero call me."

Upon hearing this, Tao Yuda, who was engrossed in processing data, paused for a moment, a hint of surprise flashing in his eyes.

Professor Lü actually chose to rest at a time like this?

That's quite a rare thing.

Perhaps it's because I've been too tired lately.

He looked at the dark circles under Lü Yongchang's eyes and pondered to himself.

The next moment, Tao Yuda snapped out of his thoughts, nodded, and responded softly.

"Don't worry, Professor. It's just some basic data processing work. Academician Cao and I can handle it."

……

"Whoosh!"

The office door suddenly opened.

Lü Yongchang walked into the office in a hurry.

The moment he entered the office, Lü Yongchang could no longer contain his excitement!

His face flushed slightly, and he gave the order in a hurried tone: "Zero, close the door!"

"No one may enter without permission."

As he spoke, he strode quickly toward his seat!

As time went on, the strange feeling in my mind became stronger and stronger!

Seeing the office door close, he breathed a long sigh of relief and sat down in his chair with peace of mind.

"Click".

The moment the electromagnetic adsorption device started to make a sound, he couldn't wait to close his eyes.

With a slight shift in his consciousness, he entered the fluorescent green space with practiced ease.

Similar to the advancement to a Level 2 civilization, the technology tree space is undergoing a series of tremendous changes at this time!

A bright white line extends from the top of the tech tree, heading straight for the dim icon directly above!

At the same time, his gaze quickly shifted upwards!

boom!

A powerful tremor surged from the depths of my mind!

Breakthrough! Breakthrough!!

The barrier between Level 2 and Level 3 civilizations was easily broken down!

[Magnetic Field Control: Basic Shield Technology]

As the bright white line spread, the originally dim cursor became incredibly bright!

The once lush and verdant tech tree has disappeared, replaced by that familiar yet complex dim cursor!

At the bottom is the basic shield technology that serves as a marker of a level three civilization.

Within the entire field of vision, only it still emitted a soft and bright white light.

What was once cutting-edge technology has become the cornerstone technology of today!

From bottom to top, the cursor's brightness gradually dimmed, and at the very top, as before, it was shrouded in a fog, making it difficult to see clearly.

A pang of regret flashed through Lü Yongchang's mind.

Unfortunately, the essential technologies required for advancing to a Level 4 civilization are not visible.

It must be related to gravity.

Without time to think it through, he quickly "raised his head" and began to observe this brand-new technology tree.

A faint, thin line extends slowly upwards from the bright cursor at the bottom.

Subsequently, several more dim lines extended from the lower level of the secondary technology tree, successively expanding into several new dim cursors.

【Magnetic Field Control: Plasma Cannon】

Type III Laser Weapon

Planetary terraforming technology

【…】

Lü Yongchang raised his gaze again.

The cursor was so dim that only a few characters could be vaguely discerned.

Materials Science and Technology...

Antimatter...

【…】

Lu Yongchang reluctantly withdrew his gaze.

The very names of these technologies were enough to excite him.

but,

Just as you eat one bite at a time, you also need to climb the technology tree step by step.

The consequence of being impatient was returning to that familiar ward and facing that familiar Dr. Wen again.

Thinking of this very likely scenario, Lü Yongchang's consciousness suddenly shuddered.

He quickly focused his attention on the second brightest cursor.

[Magnetic Field Control: Plasma Shield]

What kind of technology is this?

Lu Yongchang looked at the cursor, which was more than half bright, with some confusion.

Could it be an upgrade to the magnetic field shield technology?

Why didn't the Lattor civilization master it?

But when he thought about the somewhat peculiar social structure and technological system of the Lator civilization, he felt relieved.

Lu Yongchang stopped his random thoughts and focused his attention on the dim cursor.

The next second, the familiar dizziness struck.

After the dizziness subsided, my previously somewhat muddled mind instantly became clear!

Every detail about shield technology came to mind, and some issues that he hadn't noticed before were discovered by Lü Yongchang at this moment!

After reviewing the knowledge already acquired, the brain's processing speed skyrockets, and electrical signals are rapidly transmitted between neurons!

……

More than ten minutes later.

The clarity brought by "overclocking" gradually disappeared, replaced by a more intense sense of chaos than before.

Having already become familiar with the process, Lü Yongchang reached out and grabbed a packaging bag from the side. After opening the straw, he took a deep breath of the highly concentrated nutrient solution inside the bag.

A few minutes later.

"call……"

After ingesting a high-concentration nutrient solution, the feeling of mental fog decreased somewhat, but what followed was an overwhelming sense of fatigue.

"Zero, how much longer will Cao Liangcai and his team need to complete the data processing?"

He mustered his strength and asked.

The holographic projection quickly unfolded, showing a busy scene inside the laboratory.

"At the current speed, it will take another three to five hours."

Upon hearing this, Lü Yongchang glanced at the holographic image and then closed his eyes again.

"Call me when they've finished organizing the data."

"receive."

The moment the words were spoken, the office lights automatically turned off, and the indoor temperature was automatically adjusted to the most comfortable range for the human body.
