In fact, Yin Gang said that he was the originator of 4D, and he really didn't brag, because this concept was formed by his father after he asked him a naïve question when he was a child.

He was only five years old at the time, and he asked his father curiously, "Dad, why can't you turn back time?" ”

"Because time is like water in a high place that cannot flow to a low place."

"Then why does the water return to heaven? The sky is very high, why can water go to the sky? ”

It was a question that had always been on his father's mind.

He repeatedly studied Einstein and Hawking's theory of time holes, and many years later, wrote a paper that caused a sensation in the academic world:

There are several parallel but not interfering spaces in the world, and a mirage is the coexistence of different real spaces at the same time.

Dad believed that if the form of time was changed, such as changing the form of the downstream to the counter-current, or to the rotating form, people could enter different spaces, thus realizing the so-called time travel.

Although my father only taught his hard work to Hanhaitang, a proud protégé, as his son, he had heard him nag thousands of times during the dinner table.

I've been trying to turn this tantalizing theory into reality, but I've always been stuck in the calculation of changing the form of time.

This makes me desperately think that my father's thesis should be similar to the false proposition of turning water into oil, right?

How can humans control and reverse time?

But now he is supported by Han Momo, who doesn't know the height of the sky, and in order to subdue her, he must thoroughly verify the feasibility of this theory anyway.

He immediately put everything down and wrote it day and night.

Of course, he didn't let his guard down, for fear that she would think of a way to escape and let Ah Lie keep an eye on her.

Han Momo had a computer and settled down to program.

Motivation, efficiency, she writes very hard, because she also has a goal -

If you can write successfully, it means that you can travel through time and space, so how can Yin Gang shut himself?

Bai Xiao choked on a mouthful of water, coughed violently, woke himself up, and immediately threw himself in the water, his feet and hands touched the cold stones.

He struggled to keep himself afloat, and his head finally came out of the water, and it became safe for him to breathe.

It was pitch black, and nothing could be seen, except the sound of rushing water.

He straightened his body, tested the depth of the water, and stepped on the solid bottom.

Fortunately, the water is not deep, but it reaches the waist.

I've never seen such a dark night, and I don't know where I am.

The water is turbulent and the air is damp and stuffy.

He didn't dare to move anymore, listening to his surroundings with his ears.

Gradually, the sound of water was heard in the sound of rushing water.

The tick was amplified by a horn, with an echo.

Only in an enclosed space is it possible to have an echo.

He recalled that he was at the well before he fell unconscious, and that apparently someone had attacked him and threw himself into the well?

If it's a well, you should be able to see the sky overhead.

Even on a dark night without starlight, the clouds reflect the lights of a big city, and there is always some bright light.

But above his head, there was exactly the same black everywhere, and there was no circle of bright color at all.

Could it be that the mouth of the well has been covered?

He reached up, not hoping to touch anything, only to touch the rough rock.

Isn't this inside the well?

But inside the cave?

If it's a cave, there's always an exit, and at the exit, there should be a wind blowing.

He carefully searched for the direction of the wind.

The air moves slowly, but it is still sensitive to the cooler air at a 45-degree angle.

He walked slowly and slowly in the shaded direction.

In some places, the roof of the cave was so low that he had to bend down to pass it; In some places, the hand cannot touch the top, but the rock walls on both sides can be touched.

In some places, the water was so deep that it almost covered his head, and he had to swim forward.

In this way, guided by the temperature, he marched.

He didn't know how far he had gone, but after turning a corner, he saw a faint light.

Something was shaking in that light.

Continuing to get closer, I saw clearly, it was a windmill wheel.

He immediately sped up his march.

Where there are windmills, there must be people!
