Yes, that's right.

It's the laws of space-time!

Lin Xian had a flash of inspiration and came up with this term, which he found very fitting.

"There should be many, many more laws of space-time, many that I haven't noticed, haven't paid attention to, haven't deduced."

"But so far, I can only comprehend three..."

He picked up his pen again and wrote down the three laws of space-time that he had summarized on the paper:

[Laws of Space-Time]

[1. Space-Time Butterfly Effect]: Any action at the current point in time will continuously affect history over the next hundreds of years, thereby causing greater or lesser changes in the future world. Small changes may be imperceptible, but large ones can subvert the world.

[2. Space-Time Variation]: Due to human intervention in history, the original course of history will be disrupted, leading to changes in the future world. This change is called a space-time variation. It is worth mentioning that space-time variations are uncontrollable.

[3. Variation Anchor Point]: A time and event that is already in an irreversible state and can cause observable space-time variations is called a variation anchor point.

……

Lin Xian looked at these three summarized laws of space-time.

It felt like something was missing.

He carefully reviewed them and found that the descriptions of the first law, the Space-Time Butterfly Effect, and the third, the Variation Anchor Point, had some conflict.

"Will every single thing necessarily trigger a space-time variation?"

Lin Xian felt that this was impossible.

If every small thing was enough to cause a future space-time variation, then his dream could not have remained unchanged for 23 years.

His winning the championship of the Youth City Parkour League for three consecutive years was a very obvious act of changing reality, but it did not cause the slightest ripple in the future world. The world 600 years later did not change because of Lin Xian's small achievements.

Lin Xian looked at the water glass on the table, which contained half a glass of water.

He began to think...

Would drinking this mouthful of water have any impact on the future world 600 years later?

"That's definitely not going to happen."

Lin Xian was very sure:

"Unless I drink a ton of water now. Then I would die directly, or even if I was rescued, I wouldn't live to be very old."

"In that case, I might not be able to get married or have children, and the Lin family's bloodline would be cut off with me. The Lin family scientist who should have been born would be gone, and the Lin family criminal who should have plagued the world would also be gone. That would indeed trigger a space-time variation."

"So, this is a matter of [quantitative change leading to qualitative change]. Not every Space-Time Butterfly Effect is strong enough to affect the future hundreds of years later."

"Small things like whether or not to wash your face, brush your teeth, or take a shower will be gradually smoothed out and diluted in the 600 years of space-time, without any waves."

Therefore.

Another supplementary clause must be added to the laws of space-time.

Lin Xian picked up his pen and continued to write the fourth law of space-time:

[4. Space-Time Elasticity]: Space-time itself has a certain degree of elasticity. Not every Space-Time Butterfly Effect will trigger a space-time variation. A certain amount of cumulative change, or a sufficiently strong change in reality, is needed to break through space-time elasticity and cause a space-time variation, thereby affecting the future world.

Lin Xian guessed that the longer the time scale, the greater the space-time elasticity should be, and the less likely it is to change.

This elasticity is also a kind of inertia, which will be smoothed out by a long enough time span and become less sensitive.

But the conclusion of inertia is not necessarily accurate, so Lin Xian did not write it down.

……

"That's it for now."

Lin Xian closed the pen cap.

[Space-Time Butterfly Effect], [Space-Time Variation], [Variation Anchor Point], [Space-Time Elasticity].

These are the four laws of space-time that Lin Xian has currently comprehended.

More laws may be comprehended in the future, depending on how deeply the exploration of the dream can go.

"Perhaps these laws... on the scale of space-time, are weapons no less powerful than airplanes, tanks, and cannons."

Lin Xian closed his eyes and began to imagine...

How difficult would it be to bombard the entire Donghai City with airplanes, tanks, and cannons, turning it into a flat land and reverting human technology to the 1980s and 1990s?

Very, very difficult.

This is not just a matter of how much ammunition is needed. Even if nuclear bombs were used to flatten Donghai City, technology would always be revived.

What's more, if the enemy really had this idea, they would have to ask if the Dragon Kingdom's defense capabilities would agree. With such strong air defense and sea defense capabilities, how could they let airplanes and tanks flatten Donghai?

But the laws of space-time, this kind of [space-time weapon], is different!

This is a war without smoke.

You can't see where the enemy is, don't know who the enemy is, and can't even defend against the enemy's attack at all.

[Space-time weapons] can fire shells 600 years ago, easily changing history and the future with [laws of space-time], making it impossible for you to defend.

Just like that question just now.

How difficult is it to break through various defenses and flatten Donghai City?

For someone who has mastered space-time weapons and the laws of space-time, it is not difficult at all.

Xu Yun's paper is enough.

"This is war on the scale of space-time..."

Lin Xian looked at these four short lines of text on the manuscript paper, but felt the enormous energy of destroying the world:

"This is a... space-time weapon that only I possess."

He had a sudden idea.

Since his space-time weapon accidentally caused the technology of the future world to regress by decades... then maybe it can be recovered, allowing the future world to change again and let technology lead by decades, or even hundreds of years.

"An interesting attempt."

Lin Xian crumpled the written manuscript paper into a ball, threw it into the baking pan, and lit it with a lighter:

"But space-time variations are uncontrollable."

"If you don't want to do more harm than good... you still have to figure out the truth about the technological regression in the dream world first."

"Technological regression cannot happen for no reason. There must be a special reason."

Lin Xian believed.

As long as the number of space-time laws comprehended and mastered is sufficient, maybe one day, he can really control the Space-Time Butterfly Effect to a certain extent, making space-time variation a [controllable] thing.

Whoosh...

The flames danced.

Each flame jumped in an unpredictable direction.

Lin Xian planned to fall asleep early tomorrow afternoon to investigate everything in the dream as soon as possible.

……

The next day.

While Lin Xian was working in the office, he received a call from his university counselor.

He was quite surprised.

The male counselor had entered the school to work after graduating with a master's degree. All tenured teachers had to start as counselors. Because he was very young, he got along well with the students.

Lin Xian had a good relationship with the counselor in college. He didn't know what he wanted from him.

As soon as the call was connected, the counselor congratulated Lin Xian cheerfully:

"Rhine Cat is very popular now, Lin Xian, especially among female college students. It's so popular that it's out of control."

"By the way, do you have time these days, Lin Xian? The freshmen I'm in charge of this year know that Rhine Cat was designed by a senior from our college, and they're all very excited. I was so proud that I boasted that I would invite you to our college to give a small lecture to share some experience in the field of IP image design with the younger students."

Lin Xian smiled helplessly after hearing this.

It's true that Rhine Cat is very popular, but it wasn't designed by him... What experience can he share? At most, he can only share the posture of dreaming.

But the counselor was too enthusiastic and asked him to give him some face and establish some prestige in front of the freshmen. Lin Xian agreed:

"How about tomorrow afternoon?"

"Okay, tomorrow afternoon is a good time."

Because Lin Xian was planning to enter the dream early this afternoon to explore, he scheduled the small lecture for tomorrow afternoon.

"Sigh."

After hanging up the phone, Lin Xian sighed.

Since he had agreed, he had to prepare well.

He picked up the black notebook on his desk, drafted a speech outline on it, and prepared to bring this notebook to the lecture tomorrow to speak from.

After finishing his work, Lin Xian went home early to prepare to enter the dream.

He looked at the time.

It was not yet six o'clock. If he entered the dream now, he would have a full 7 hours to explore, which was still very sufficient.

After a simple wash, he lay down on the bed.

He fell asleep.

……

……

……

In this new dream, the summer was still hot, but you couldn't feel any of the dry summer wind.

Probably because there were too many intricate and messy self-built houses around, and various small roads were rugged and difficult to walk on, so even the wind couldn't blow in.

Lin Xian opened his eyes.

It was the same "birth point" as when he last entered the dream.

Brick walls, low houses, narrow roads, lanterns, stone tiles, moss...

It was still that dilapidated and poor small village.

"Is this really still Donghai?"

Anyway, the city in the first dream was still called Donghai. But is this still it now?

Lin Xian scratched his head. It was currently difficult to determine.

But you could just ask someone.

"Thief—catch the thief! Young... young man! Help!"

Behind him, came the anxious voice of a middle-aged woman.

Turning his head to look.

He found a delicately dressed aunt panting and chasing after a running thief in front.

The thief was wearing a black hat, cursing in his mouth, and was the very one who stole the convenience store's cash box and killed Lin Xian with a dagger last night!

"Can't you steal from another village!"

Lin Xian was really speechless.

This thief was targeting one village to fleece hard, stealing from the old man's convenience store at night and robbing the old woman's handbag during the day.

"Get out of the way!"

The black-hatted thief elbowed Lin Xian away and ran towards the path ahead.

The aunt behind ran over and grabbed Lin Xian's arm:

"Young... young man, I can't run anymore! Can you help me..."

You only stabbed me to death yesterday, and you still want to run away today?

"Okay, Auntie, you wait for me here."

Whoosh!

He activated his parkour skills and jumped left and right on the small road, catching up with the thief after a few wall jumps.

"Go you!" "Ah—"

He kicked the thief down with a flying kick and pressed him to the ground.

This time he had learned his lesson.

He didn't rush to snatch the handbag back from the thief's hand. Instead, he reached to his waist with his right hand, pulled out the shining dagger, and threw it far away.

Clang.

The dagger bounced a few times and rolled under the stone steps.

He thought it was safe, but—

Swish!

Another crescent flash of cold light flashed past. The thief actually took out another sharp knife from his arms!

"Dual wielding?"

Fortunately, Lin Xian was prepared and jumped back to avoid it.

What's going on in this world now?

CC in the last dream carried two guns.

The thief in this dream also carries two knives.

Is everyone so insecure?

"You motherfucker!"

The thief bared his teeth, rubbed his neck that Lin Xian had pressed painfully, and walked over quickly, holding the sharp knife:

"You're just nosy, aren't you!"

Lin Xian retreated.

Thump.

There was no way to retreat. It was a dead end behind him.

"Damn it!" The thief's face was ferocious, and he waved the sharp knife in his hand to approach Lin Xian:

"I'll teach you a lesson today!"

"Who the fuck do you want to teach a lesson to!!!!!!" A loud roar came from the alley next door.

Boom!!!

The pile of firewood that had been piled up at the entrance of the alley was kicked open!

A fat body led three fierce-looking younger brothers out from behind!

Swish!

The leader flicked his hand vigorously, and a meter-long whip appeared in his hand.

"Ptooey!"

He spat out the cigarette butt in his mouth, and the horizontal flesh on his face twisted into a ball. He stared fiercely at the thief:

"You dare to steal things on my territory..."

"You're rebelling!!"
