I am really a time traveler

"There's no need to worry too much. For us, as long as technology can develop to ensure our own safety, that's enough."

"For example, in the case of the four-dimensional creature, that thing is the biggest threat."

Speaking of this, Lin Yichen couldn't help but rub his eyebrows, but he felt that this thing was very troublesome.

At least until now, Lin Yichen has not figured out how to deal with this four-dimensional creature.

One thing is that there is another idea that has been appearing in his mind, but Lin Yicheng is unable to determine it yet.

Earlier, there was someone from another timeline who reminded him.

When the countdown for the time travel ends and it is time for him to leave, he must leave, otherwise some trouble will arise, which will be very dangerous and will endanger their lives.

Since then, this matter has always lingered in his mind, but Lin Yicheng still doesn't know what the trouble is.

It was not until the four-dimensional creature appeared later that Lin Yichen thought that the other danger he mentioned might be this four-dimensional creature.

The other party is already in the time dimension, and after some delay in returning, some fluctuations in the time dimension will occur, and then they will be noticed by the creatures in the time dimension.

But even so, everything should be fine after leaving that world in the end.

Could it be that after the other party returned, he still attracted the attention of the four-dimensional creature?

Lin Yicheng fell into deep thought.

According to his current speculation, when he returns later, the technology on his body that can take him through time will inevitably cause some fluctuations in time.

But as long as I can escape, there shouldn't be a problem.

But according to the previous message from another self, it was obviously not what he thought.

It’s really troublesome. There is too little evidence and it’s too difficult to guess.

Thinking of this, Lin Yichen couldn't help but rub his eyebrows.

Could it be that the other party has returned to that world many times, or that after leaving traces of time there, the world he travels to in the future will often go to that place?

Lin Yichen frowned, his mind full of random thoughts.

At this time, Qi Xuexiao, who was standing by, also began to ponder after hearing what Lin Yichen said.

What she was thinking about was actually what Lin Yichen had just said.

At present, there is still some threat from the world to them.

The biggest threat would probably be a nuclear war, but at the moment there is no madman who would rashly start a war of this magnitude.

Another thing is that they have Xiaoxing here, so if someone really starts a war of this level, they will know it first.

At that time, we can also counterattack immediately to minimize the losses.

In fact, Lin Yicheng had talked to her about this a long time ago.

However, at that time, the reason why Lin Yicheng did this was that he wanted to try whether he could directly terminate the war when the other party was about to start this level of war.

The way to end it is to seize control of the other party’s nuclear weapons.

However, Lin Yicheng was somewhat disappointed that this approach would not work.

Because the control of the opponent's nuclear weapons and the like is in the hands of humans, not computers.

Perhaps the other party had been prepared for this move a long time ago.

Among these nuclear weapons, the easiest to set up are computer-controlled roadbeds, not to mention air penetration and underwater nuclear submarines.

Both of these are actually controlled by humans.

However, although there is no way to directly control these weapons, Lin Yicheng can make some predictions by monitoring their conversations.

Relying on these things, Lin Yicheng has actually mastered a lot of the opponent's secrets, but many secrets are still not available.

For example, Lin Yicheng knew that there was a very special basement in the basement of the other party’s office building.

Many of the other party's confidential matters were discussed there.

When having a conversation in this place, you are not allowed to bring any electronic devices, record the conversation, or take any paper materials away.

Even if any documents are brought in, they will be destroyed on the spot after the investigation is completed, and then the personnel will leave.

It can be said that this place is isolated from all means of eavesdropping.

Unless the people inside have betrayed us, it would be impossible to steal the content of the conversation.

However, for now, Lin Yicheng is unable to obtain the information inside.

But as of now, Lin Yicheng is not very concerned about the content of the other party's conversation.

As long as the other party doesn't act like a lunatic, once they develop and officially enter the universe, basically nothing on this planet will be able to threaten them.

After all, the most powerful weapon on this planet can only be used on this planet and cannot be used outside the planet.

And if the other party really uses a rocket to carry out a space attack, it would be very easy to intercept it with such a slow speed.

Overall, their current threat is still the four-dimensional creature.

Sometimes when those guys take action, there is no logic at all. They just destroy a civilization.

And when it is destroyed, you will have no idea it is gone all of a sudden.

This was Lin Yichen's partial understanding of this four-dimensional creature before.

Perhaps, the civilization that the other party tried to wipe out was just as simple and boring as when humans were children pouring boiling water into ant nests.

Before having any conversation with the other party, Qi Xuexiao really didn't know the logic and purpose behind the other party's actions.

Thinking of this, Qi Xuexiao also sighed.

As she learned more and more from Lin Yichen, she sometimes became anxious.

Fortunately, there is still hope for the future. It is not the kind of situation where there is no hope at all.

In this respect, it is better than the Earth civilization in The Three-Body Problem.

"We can't deal with those threats at the moment, so we can only put them aside for now. If we really want to be able to deal with that kind of threat, do we really have to fight a battle with the four-dimensional creatures?"

Qi Xuexiao knew that the biggest threat Lin Yicheng was referring to was four-dimensional creatures.

As for the rest of the guys on Earth, there is a threat, but it's not particularly big.

After all, the worst case scenario is that when a war of this level starts, Lin Yicheng knows nothing about it.

But once the opponent's missile is launched, even if Lin Yicheng's reaction is so slow, he will know it at the first time.

At that time, you can start calculating the other party's final destination.

To put it bluntly, people like Lin Yicheng can fly.

As long as they calculate where the missiles will land, they can avoid the bombing in the shortest time possible.

Considering the territory they have here, it is still possible to hide away.

Not to mention, they can also fly into the air.

What they are worried about is just how much damage the other party will cause them.

No matter what, future development still needs to rely on these factories and the resources here.

If these things were destroyed, it would be very difficult to redevelop them in the future.

At the moment, they have jade and the other side has the jar. It would be very irrational to touch the other side.

In addition, in order to prevent the other party from really using this trick, Lin Yichen has actually tried his best to add some new weapons to the people above.

Then let the people above display these weapons, so that they can have a warning effect.

If the other party is afraid, he will not act recklessly.

After all, if people know they can’t win once a fight starts, few will still insist on fighting.

"Well, then we might really have to fight each other."

Lin Yicheng listened to Qi Xuexiao's words, nodded slightly, and then sighed.

There are threats from Earth, but they are relatively small, so Lin Yicheng usually asks Xiaoxing to monitor them.

Only the four-dimensional space always felt like a stone pressing on his chest.

The most important thing is that Lin Yichen was wondering if he should delay his departure, as it would attract the attention of these guys.

In addition to being able to erase people out of thin air in time, does the other party have other methods?

Lin Yicheng is still unaware of this.

But if possible, Lin Yicheng doesn't want to try the other party's methods.

If you try without knowing what the other party's methods are, you may die without knowing how.

If you really want to try it, the best way is to go to other worlds and let some insignificant civilizations collide with each other.

In this way, Lin Yicheng, as a bystander, should be able to see something.

By then, if we really fight with the other party, we will have some confidence.

Another thing is that if they don't fight with each other, these four-dimensional creatures may not know how powerful they are, and may attack them for no reason one day.

This is very troublesome.

When Lin Yicheng thought of this, he couldn't help but rub his eyebrows repeatedly.

If they start fighting, they don't know what the other party's tactics will be. If they don't fight, they don't know when the other party will attack them.

It can be said that no choice is a good choice.

Qi Xuexiao also saw the helplessness in Lin Yicheng's eyes, and could only comfort him at this moment, "It's okay. At least based on what you learned before, the future development of the world, the four-dimensional creatures haven't set their sights on us yet, right?"

"In this way, we will be safe for the time being for the next few decades."

Qi Xuexiao thought that Lin Yicheng had been to his future world several times before.

Since Lin Yicheng has been there, and they are still there in the future world, it means that the four-dimensional creatures have not attacked them yet.

In this way, they still have decades to develop.

It is even possible that this time will be longer.

"I am worried that we are developing too quickly and there will be some unnecessary troubles in the future. For example, because we are developing too quickly and it is inconsistent with the original development process, it will attract the attention of four-dimensional creatures."

"You also know that the future is not set in stone."

Lin Yichen smiled bitterly.

This is actually what he is worried about.

Those guys are creatures of the time dimension. They may not care about some changes, or they may be very sensitive.

Lin Yicheng didn't know the details and it was hard to guess.

But I'm worried that it will attract their attention.

If we really attract their attention, we will be in trouble.

By then, the future world will definitely no longer be the future world that Lin Yicheng saw.

The guys in the time dimension have all taken action, so it is too easy for the other party to change their future world.

After all, the other party is above their world.

Qi Xuexiao was also stunned when he heard this. After thinking about it carefully, he couldn't help but take a breath.

It’s true, what Lin Yichen said does make a lot of sense.

Their original world was not like this, but because of Lin Yicheng's travel through time, the technology here began to develop rapidly.

By this time, it must have caused huge changes.

I just don't know if those guys have noticed the changes on their side.

If they had noticed, they would have probably already caught their attention.

It would be fine if you didn't notice.

But they are not four-dimensional creatures and have no way of knowing the specific situation.

"If only we had a machine that could enter the four-dimensional space and take a look, then we could probably find a way to develop quickly and covertly at the same time?"

Qi Xuexiao was silent for a moment, then spoke again.

The reason they are so hesitant right now is, generally speaking, because they have too little information and are unable to make effective responses.

If there is enough information, then there will be no problem.

Lin Yichen listened to this and fell into deep thought.

Otherwise, I will find a world later and create a robot to try to upgrade the dimension.

See if we can use the upgraded robot to steal some information about the four-dimensional space.

If this can be done, it will be much easier to obtain information about four-dimensional space in the future.

When Lin Yichen thought of this, a hint of excitement appeared on his face.

When Qi Xuexiao saw Lin Yicheng's expression, she knew that Lin Yicheng might have thought of something, and she also knew that Lin Yicheng was not a reckless person, so she did not try to persuade him.

Instead, at this moment, he gently reminded her, "If you have any ideas, as long as you think you can try it and it can ensure safety, then try it."

There is too little information, so we must always seek a breakthrough.

After hearing what Qi Xuexiao said, Lin Yichen nodded to indicate that he understood.

"Forget it, let's not think about these things for now."

Lin Yicheng waved his hand and looked at the factory in front of him. "Next, we can almost produce a new generation of nanomaterials. I wonder what the nanomaterials using this technology will look like?"

When Lin Yichen thought of this, a hint of curiosity appeared in his eyes.

If this batch of materials is qualified, their nanodevices can also be updated.
