Li Yanzhen runs along the Min River for half an hour every morning to maintain his considerable muscle mass and hidden physical fitness.

With a height of 176cm, faintly bulging muscles, and a resolute and righteous face, such a person would have a word to describe him "the appearance of an emperor" in ancient times

But no one would have thought that such a look, two years ago, was an ugly fat man who endured terrible school violence.

"Huh-" Li Yanzhen stood by the river and punched twice, mixed with the obvious sound of breaking the air.

"No, the punching speed will decrease after each run, and theoretically the increase in physical strength will continue the duration of the explosive power, but the improvement speed is a bit slow. Li Yanzhen looked at his fist.

I looked at my watch, it was only half past four, I went home at five o'clock, took a shower, and went out to school at six o'clock.

It's still a long time, so I just sat on the bench and looked at the scenery.

The Min River is a tributary of the Yangtze River, located in Sichuan, looking at it in the early morning, quite a sense of beauty, at this time it is summer, the cool breeze mixed with the slightest moisture on the cheeks, making Li Yanzhen extremely comfortable.

Li Yanzhen just sat like this, slowly exhaling his breath, enjoying the comfort of half an hour.

"Da, da, da......"

"Wow, whoa, whoa......"

Li Yanzhen sat down, and the sound of the watch hands turning and the sound of running water seemed to gradually come together.

Li Yanzhen woke up violently, looked at his watch in surprise, and his eyes kept going back and forth between Minjiang and the watch.

He was begged by a sudden coincidence.

"Does time really exist?"

He pondered.

Time, in a broad sense, cannot be seen or touched, but it affects everything in the world.

We people die because of the constant movement and metabolism of each cell, until the last bit of energy is consumed and dies, and such cells continue to die until they can no longer support the operation of this living organism.

So what does our death have to do with time?

Just like the water of the Minjiang River, the waves flow endlessly, until one day there is not a drop of water left at the source, its life is exhausted, and death is an autonomous act.

It is the same with all things in the world.

Time in the narrow sense is nothing more than a watch in the hand, a physical quantity used to calculate the motion of an object.

After combing through it, this theory seems reasonable.

Thinking of this, Li Yanzhen clenched his fists and felt very glad that in the dark, there was no time for such an ethereal thing to dominate this body.

"My body is free. Li Yanzhen muttered.

"However, when my body runs out of cells, I will die."

"Hiss~ Why do my body cells only keep consuming to death?"

The cells of the human body are consumed with constant movement, and when people are stationary, they are actually moving internally, and what supports human beings in constant movement is eating.

Constant ingestion, air, moisture, meat.

People ingest a lot of nutrients and act on themselves, but these substances are only used as energy for people, and cannot replace the cells of the body.

When people die, all the things they take from the earth are returned to the earth.

It seems like a normal relationship.

But is it any good for the earth to produce human beings and establish such a material relationship with them?

It does not seem to have much improvement on the global environment, on the contrary, the damage is more serious.

So why exactly?

Minutes and seconds passed.

Li Yan really wanted to be fascinated.

"That's right!" Li Yanzhen was so excited that he smashed the wooden bench out of a hole.

After death, the materials that consume the earth will be returned to the earth in different ways, on the surface, the earth seems to have no loss of material, but in this human beings in addition to the material, there are other things!

Mind, Knowledge, and Soul!

When people die, they return all their material to the earth, but what about their knowledge and thoughts?

Where did all this go?

Could humans be just tools for the planet to derive knowledge?
