Volume II, Chapter 2, Wall on the Left, April 2117

That night, Zhang Weining lay on the table, next to the microscope he had used during the day, and fell asleep.

In the dream:

He stood on the plank path of the cliff, with the cliff on the left and the abyss on the right.

Zhang Weining looked up, he couldn't see the sky, nor could he see the clouds, there was space above, and there were countless starlights.

"Are you looking for clouds? Or are you looking for the sky? A voice said. Zhang Weining followed the voice and looked at it, not far ahead, there was a man standing just now

Not there, as if it appeared there suddenly.

"You should look down, the clouds, and the sky, are under your feet," the man continued, "I mean, stratosphere, you're standing in the stratosphere now,

The flight flew at an altitude of 18,000 meters below before reaching the ground. ”

Zhang Weining did as the man said, stretched out his head from the plank road, and looked below: the clouds were really below, and the vast sea of clouds covered the earth.

"If you're afraid of falling and falling to the ground," the man said, "we can raise the altitude a little bit more to the edge of the atmosphere, and that's it."

Come, when you fall, you don't fall to the ground. ”

(Why?) Zhang Weining thought subconsciously.

"You'll be like a shooting star, huh-" the man drew an arc in the air with his hand, "burning in the air, with your mass, I mean, you tiny."

The body, before it could hit the ground, burned out in the air. ”

"Speaking of which, young man, it seems like you're not afraid of falling?" Zhang Weining asked.

"Why should I be afraid?" The man smiled confidently.

"You are also human, so you should be afraid too." Zhang Weining said.

The man smiled sarcastically, turned around and walked along the plank road, walking into the distance: "Follow me, you will understand." He said arrogantly to Zhang Weining.

(Hmph, why should I follow you?) Zhang Weining looked at this person very pleasantly, and he decided to go in the opposite direction.

"Don't say I didn't remind you that that direction doesn't work," the man reminded, "the direction you are taking is the past, and the direction I am going is the future."

Time points to the future, you should follow me. ”

Zhang Weining snorted in his heart, ignored the man, and continued to walk in the opposite direction. Zhang Weining saw that it was obviously wise to go in the opposite direction, because

In the opposite direction, the plank road is getting wider and wider, and it is not easy for people to fall down.

At this moment, Zhang Weining suddenly found that the plank road in the opposite direction suddenly began to collapse piece by piece and fell into the sea of clouds. He was stunned and stopped.

Seeing that the plank road in the opposite direction kept falling into the sea of clouds, and it was about to collapse to his feet soon, Zhang Weining took a few steps back, and then, he didn't

Don't choose to follow the man and walk in the right direction.

"I said, that's the past, you can't go back to the past, you have to follow me." The man said.

Zhang Weining was resentful and couldn't wait to push this man off the plank road. He followed the man, slowly approaching, and he held out his hand......

At this moment, Zhang Weining suddenly noticed that the plank road in the positive direction was getting narrower and narrower.

In the end, there will be no way out.

However, in the rear, the plank road in the opposite direction was constantly collapsing, and he and the man could only move forward.

"The plank road ahead is getting narrower and narrower, and we will all fall down in the end." Zhang Weining said to the man in front of him tremblingly.

He didn't meet, and the man in front of him just laughed indifferently: "Of course I know that we will all end up with no way out, but what about my way,

It's still a long way, and you're ...... way."

Zhang Weining suddenly found that the man's body was constantly getting smaller, and the narrower the road, the smaller his body became.

"You, you can be smaller." Zhang Weining exclaimed.

"What's so strange about that," the man said nonchalantly, "I'm not human. ”

(Ah what?) Zhang Weining was taken aback again. "What are you?" He asked the man in front of him.

"I am," the man smiled back, "potted leaf virus!" ”

(Potted leaf virus?) Zhang Weining recalled the new virus found in the potted plant during the day.

"I don't believe it," the man said, his body still getting smaller as he walked, "My real body is only the size of a virus, you can follow me."

Go down and you'll see. ”

The plank road in the opposite direction was constantly collapsing, and Zhang Weining could only walk forward with this man.

It didn't take long for the man's body to become the size of a rabbit. At this time, Zhang Weining couldn't go on: under his feet, the plank road could only be accommodated

A rabbit, he almost didn't even have a place to stand.

"I don't know if you've practiced your balance skills by sticking to the wall," the rabbit-sized man turned back to Zhang Weining and smiled, "I hope you've practiced." ”

Zhang Weining smiled bitterly, his body was close to the cliff, and he didn't dare to move. However, just before he was in despair, he suddenly found that in the opposite direction, the plank road

The collapse, actually, stopped!

(Ah, this, that's great – if I could keep my balance like this, I wouldn't have fallen.) Zhang Weining thought, (Damn rabbit!)

Zhang Weining glanced at the man who was walking away from the other side, and now, his body was no longer the size of a rabbit, but only the size of a mouse.

Zhang Weining was about to lose sight of him.

In the dream, to maintain balance, after all, no physical strength is needed, Zhang Weining breathed a long sigh of relief. However, just as he had just relaxed, it was less than 10 seconds

, he suddenly found that his body actually began to get bigger, (this, what's going on?) Zhang Weining found that his hands had become the claws of dinosaurs

son, and his own skin has also begun to grow green dragon scales!

(I'm a dinosaur?) Zhang Weining screamed and fell into the abyss.

When he woke up from the dream, Zhang Weining was already sweating profusely, he rubbed his eyes, and found that it was late at night, and he said to the air: "Serra, drive down."

Lamp. ”

"Yes, master." Serra, the artificial intelligence butler, turned on the room light, and the light was slowly turned on so that the human eye could slowly adjust to the brightness.

Zhang Weining came to the study, and from the bookcase, he took out a notebook, a very old notebook. He patted the ash on it and flipped through the notes, which were more than 40 years ago

, when he was an 8th grader, he took notes.

The Left Wall Law:

To put it simply, creatures are taking the most basic form as the "left wall", and they will inevitably continue to develop to the right, and there will definitely be creatures that are getting stronger and stronger in the competition

Big, eventually, they will be so strong that there are no natural predators on the planet, and without predators, they will overbreed and multiply dramatically until the environment is no more

The way to support their huge numbers and consumption, environmental pollution, or environmental upheaval, the first to become extinct are these powerful creatures, such as dinosaurs

。

In that notebook, it was written.

Zhang Weining looked at these lines thoughtfully, (These truths are understood by 8th grade students, but...... In Zhang Weining's mind, the dream just now is still there

However, it is vivid in my mind, and now it seems that the road of human beings is indeed getting narrower and narrower.
