"You're early, too."

Chen Du didn't hold a position in the class, and he and Tang Jing had only discussed some math problems before, and he and Tang Jing had probably said more in the past two days than in the previous three years combined.

"The snoring of the thunder is terrible." Tang Jing stretched out the tip of her tongue and complained slightly.

She was on the first shift last night, and she could go to bed at about 10 o'clock in the evening, and she didn't actually do any physical labor yesterday, so she followed Chen Du to fetch water, and washed up by the way, but she slept better than others.

"Haha, he was too tired yesterday." Chen Du also laughed.

"You're busier than him, why don't you sleep more?" Tang Jing asked.

Chen Du said: "I found that our awakening ability, using something similar to mental power, even if it is overconsumed, it will not cause fatigue, just dizziness, but the recovery will be faster than physical strength, after sleeping last night, now it seems that there is no feeling at all." ”

"When you climbed the desk yesterday, you took a long break because of dizziness?" Tang Jing asked again.

"That's right, I didn't know what to expect, so I took the safest move."

"You're doing the right thing, we still don't know much about this so-called ability." Tang Jing sighed.

Chen Du also wanted to use Tang Jing's mind to help analyze his ability, so he took the opportunity to say: "I found that after the mental power is consumed, it will increase to a certain extent if it recovers again, which is a bit similar to physical exercise, but the effect is more obvious. ”

Tang Jing nodded: "This is reasonable, if there is no growth, the help of the ability to human beings is actually very limited." ”

"How?"

"I think it's ultimately a question of scale."

"Scale?"

"Yes, for example, now, with the ability of you and Da Lei, we can easily solve it in the face of ants of this size, but it is almost useless to encounter mice, or even bigger cats and dogs."

"That's right." Chen Du nodded.

"Well, there are only two ways for humans to get back to the top of the food chain."

"What?"

"The first is the growth of abilities, such as the power of the thunder that grows until it can fight elephants with bare hands. Or your ability to control a house. ”

"It can't be."

"Why?"

"I don't know, I just feel very disagreeable." Chen Du shook his head.

"Your feeling is very likely to be right, because the gap between organisms in scale cannot be directly bridged by physical confrontation, for example, if bacteria want to kill humans, they must destroy our bodily functions, rather than bite us head-on."

"So there's a second way?" Chen Du asked.

"The second way is to develop technology, or rather, technology based on abilities."

"Technology ......"

Although it had only been two days since the end of the world came, Chen Duan seemed to have become very unfamiliar with the word.

"When human beings controlled the world, they didn't rely on their bodies, no matter how strong people were, they couldn't be stronger than lions and tigers, we invented guns, automobiles and airplanes, not just to make up for our own shortcomings."

"But why, it's technology built on abilities?" Chen Du asked.

"Because a lot of human science and technology in the past have to be built on a certain scale."

"Scale again?"

"That's right, a steam engine, even if all its parts are perfectly reduced to the same proportions as we have now, will not work, and similarly, an internal combustion engine, an engine, or even a simple screw, after being reduced in size by 100 times, may not work normally."

"Why?"

Chen Duan couldn't understand what Tang Jing said for a while, he always felt that as long as the human race was given enough time, he could return to the previous level of technology.

Everyone drives to and from work every day, goes home to light a fire and cooks, watches TV, and plays on the computer, which is nothing more than a miniature version of the world. But listening to Tang Jing's meaning, such a world will never be realized.

"I know it sounds counterintuitive, but it's easy to understand, for example, an ordinary candle can shrink it by a factor of 100, but the flame it ignites will not shrink by a factor of 100.

"There are many phenomena in physics that cannot be scaled simply equally."

"Seems to make sense." Although Chen Duan couldn't fully understand it, he also understood a little bit of the meaning, in this regard, ten of him was not enough for one Tang Jing to fight.

Tang Jing said: "Of course, theoretically, we can also manufacture mechanical equipment of the same size as before, and then operate it through a series of excessive means, but how long it will take, it is unknown, human beings in the short term, I am afraid that they can only do their best to ensure survival, once several generations do not pass on knowledge, a fault will be formed, and the original civilization may never be recovered." ”

Chen Du was silent for a long time, and then asked, "So, the ability is more important than we thought?" ”

Tang Jing nodded: "This is not only the basis for our survival, but also the basis for the re-emergence of human beings." ”

Chen Du smiled: "I found that you are very demagogic when you speak, and you must be very profitable to do pyramid schemes." ”

Tang Jing smiled indifferently: "Chen Dui, have you ever thought that your ability may be much stronger than you imagined." ”

"It's a little bit more useful than I thought at first, but at the moment, I'm only able to make simple tools." Chen Du was a little helpless.

Tang Jing smiled: "Isn't the reason why humans are different from other animals is because they learned to use tools at the beginning? Isn't it the biggest advantage that you're already the first to have access to the tools when everyone else is still in a primitive state? ”

Chen Duan also somewhat understood the meaning of his ability at this time, and he did have a great advantage before the industrial civilization was completely restored.

But this has two premises.

First, he's powerful enough to manipulate larger objects and perform more elaborate manipulations, which would otherwise take a long time to get even a flat plastic bucket to make.

Second, and most importantly, he had to be able to live.

This ability is currently very limited in terms of combat effectiveness, and if you encounter three or five ants, you will probably have to gg, and it will be ridiculous to talk about the future of human technology.

He helplessly spread his hands to Tang Jing and said, "Let's talk about how long we can live." ”

Tang Jing didn't continue the topic, a trace of embarrassment suddenly flashed on his face, and asked, "Aren't you going in yet?" ”

Chen Du was puzzled at first, and then suddenly woke up.

People came out early in the morning, obviously not specifically to greet him, but also to solve personal problems.

"Uh-huh, come out and breathe, and I'll go back, you...... Self-......"

After Chen Duan finished speaking, he found that this was a bit ambiguous, but it was not easy to explain, and if he said more, it would only get darker and darker, and he hurriedly ran away.

Leaving Tang Jing a little crying and laughing.
