Returning to 1949, I decided to hand it over to the state.

However, the doorknob seemed to be welded to the door, and no matter how much force Jiang Fan used to push or pull it, it wouldn't budge.

Jiang Fan released his grip, blinked twice in confusion, and was filled with doubt.

"What does this mean? I can only look but not access it? Is there some prerequisite for opening it?"

Jiang Fan was increasingly confused about this broken little watch.

Each time it travels back in time, it comes up with some inexplicable new tricks.

First, they gave me three fixed teleportation coordinates in 1949, then they unlocked a cubic meter of personal space, and now even a portal to the future "2126" has appeared.

What's most infuriating is that the door was right in front of them, yet they still couldn't open it. What kind of nonsense is this?

Jiang Fan muttered to himself in front of the door for a while, and tried several times, but still found it was no use.

He didn't continue to argue or pester them.

After confirming that there were no other changes in this pure white space except for the addition of this door, he turned around, walked to the door leading to 2026, pushed it open, and stepped out.

A flash of white light appeared before my eyes, and fresh air rushed towards me.

Jiang Fan opened his eyes and found himself standing at his front door, as naturally as if he had just returned from a walk outside.

He gave a wry smile, closed the security door, took off his shoes, and went inside.

The computer screens in the living room were still lit, and the water glasses on the table were still in the same place where he left; nothing had changed.

He couldn't help but think: I really wish I could have been in a state of timelessness like this when I went offline in 1949.

He has no idea how to deal with the mess over there, so he can only pin his hopes on the new features of this watch.

So he immediately raised his wrist and stared intently at the watch face.

A moment later, just like when he returned last time, the watch made a soft click, automatically unfastened its strap, slipped off his wrist, and fell into his palm.

Jiang Fan gripped the watch face, strode to the sofa, sat down, and stared intently at the changes on the screen.

Sure enough, new words began to slowly appear on the dial, and he immediately read them silently in his mind:

Countdown: 24:00:00

[One item may be carried (not exceeding 1 cubic meter in volume, and must not be a living creature)]

These two messages are exactly the same as the last one.

Jiang Fan was a little surprised that there were no changes in the parameters.

Shouldn't portable storage space be upgraded and expanded?

Could it be that my previous guess was wrong?

But then, a third, newly appearing line of text caused his pupils to suddenly contract.

[To advance the ladder of human progress, we gather the best of wisdom.]

[Feature Unlocked: Share Brain Knowledge]

Immediately following this text, a long, densely packed list of names began to scroll and play on the watch face. And each of these names was a household name.

Qian Xuesen, Yuan Longping, Einstein, Newton, Tesla, Marie Curie, von Neumann, Turing, Hawking, Yang Zhenning, Li Zhengdao, Feynman, Dirac...

In an instant, Jiang Fan was completely stunned.

These names are all among the most outstanding and brilliant talents in the history of human civilization; they are the true deities who propelled the wheels of history forward.

What does "shared brain" mean?

Could it be... that I can use this dial to directly access all the knowledge they've ever had?!

This crazy idea seems entirely plausible, otherwise this little broken watch wouldn't have put up such an extremely arrogant slogan as "For the ladder of human progress."

Jiang Fan's breathing became rapid.

If I could share Einstein's physical intuition, wouldn't I be able to directly unify field theory?

If we could share Qian Xuesen's engineering thinking, then going back to 1949, it would only be a matter of time before we could handcraft missiles.

If we had shared Yuan Lao's agricultural knowledge, hybrid rice could have been widely adopted in the 50s, and the problem of hunger among the people of the new China might have been solved 20 years earlier!

Jiang Fan's heart pounded, and his fingers hesitated for a moment above the touch area of ​​the watch face.

Finally, filled with curiosity, he pointed to the name "Einstein".

However... there was no response.

Just like that door to the future, not a single drop of water was splashed.

What does that mean?

The ____ does not work?

Or is it that this piece of junk is being used incorrectly?

Jiang Fan was utterly speechless: If you're going to publish something, at least give me something decent, even just an instruction manual would be fine!

Left with no other option, Jiang Fan reluctantly clicked on Qian Xuesen, Tesla, and von Neumann in succession...

But none of the names responded; they were completely gray.

Hey!

His initial enthusiasm instantly cooled.

After all that, this "shared brain" feature turned out to be just a pie in the sky; it was only for show and not for actual use.

What's the point of showing yourself this list?

However, Jiang Fan took a deep breath and suppressed his agitation.

He stopped clicking randomly and slowly scrolled down the list with his fingertips.

This string of names is densely packed, numbering over a hundred, and most of them are prominent scientists, engineers, artists, and even thinkers throughout history.

As Jiang Fan scrolled through the screen, he watched the video, and the more he watched, the more heartbroken he felt.

Any one of these people could have made him able to do whatever he wanted in 1949.

Oh no, even in the modern society of 2026, that would be enough to make him a dominant academic figure.

However, just as he patiently scrolled to the very bottom of the list, he suddenly stopped.

He saw an entry that was quite different from all the others.

The font color of that entry was exactly the same as the dim blue light emanating from the dial itself; it was lit up.

Jiang Fan's gaze immediately settled on that name:

Nikolai Gustavovich Alexandrov

This was a name he had never heard of before, whether in school or while making science videos; he seemed never to have encountered it.

But since this person is listed in this "shining stars of humanity" list and highlighted in blue, it means that this person must have made an extremely unique contribution in a special industrial field!

Jiang Fan swallowed hard, feeling a mix of trepidation and anticipation, and gently tapped his finger on the name that was glowing blue.

In an instant!

A human figure flashed on the dial and then disappeared instantly.

Immediately afterwards, Jiang Fan felt a surge of electricity flow from the watch face, along his fingers, straight to his cerebral cortex!

"Buzz—"

His hippocampus trembled violently, and countless unfamiliar images kept flashing through his mind.

He saw a middle-aged man in overalls standing next to a steam hammer, holding blueprints in his hand, explaining something to a group of young apprentices.

The scene then rapidly shifted, and Jiang Fan, from a first-person perspective, quickly skimmed through the man's eventful life.

Nikolai Gustavovich Alexandrov, chief engineer of the Ural Machine-Building Plant, USSR.

From 1941 to 1945, he presided over the comprehensive renovation of the T-34 tank production line during the Great Patriotic War, and single-handedly reduced the assembly time of a single vehicle from a terrifying 800 man-hours to a minimum of 150 man-hours.

He invented the "Alexandrov assembly line production method," which enabled the Soviet Red Army to produce more than 2 T-34 tanks during the Great Patriotic War, accounting for 40% of the total tank production in the Soviet Union during the war.

Key technological contributions: rapid prototyping technology for large castings, extreme optimization of assembly line processes, assembly tolerance control system, and wartime defective material replacement solutions.

Key character assessment: He was extremely adept at squeezing out the highest production efficiency with the simplest tools under conditions of extreme resource scarcity during wartime.

Its core engineering methodology is to maximize output under limited conditions!

A vast amount of heavy industry formulas, assembly line concepts, and fragments of knowledge surged through Jiang Fan's mind, causing his temples to throb, his vision to blur, and even his ears to ring.

"Well……"

Jiang Fan could no longer withstand this terrifying information indoctrination. He gripped the edge of the sofa with both hands, trying to control his body, but his limbs simply wouldn't obey him.

He then collapsed onto the sofa, his consciousness becoming increasingly blurred.

And that information continues to be written into his brain.

In the instant before he completely lost consciousness, a sudden realization flashed through his mind:

"Sharing a brain, it turns out, means I can directly have the same way of thinking as them..."

Then everything went completely black and he fainted.
