Su Mo stretched out his right hand and placed it on the metal hollow pattern.

He pressed it down slightly, and the hollow pattern sank into the inside.

"laugh--"

A faint sound penetrated Su Mo's ears. If he hadn't been nervous, he would probably have noticed it.

The metal wall one meter to the left changed, and the light blue metal instantly turned red.

Four light spots appeared on the surface of the wall at the same time. The four light spots moved quickly and connected together on the wall, perfectly drawing the shape of a door.

"Click—"

Another slight metal impact sounded, and the metal door slowly shook in.

Then, a pitch-black metal passage appeared in front of Su Mo. He looked inside and finally came to a conclusion of five words.

Nothing can be seen!

After thinking about it, Su Mo opened the golden eyes of the igneous eyes, but with the blessing of the golden eyes of the igneous eyes, the visibility in the passage was less than two meters.

The dark metal passages and the silence of the entire metal city create a strange atmosphere.

However, these did not affect Su Mo.

He never believed in the theory of ghosts and gods.

Enter--

Taking a step, Su Mo walked into the passage.

If you are not afraid of being afraid or not, you should still have the necessary vigilance.

After all, who knows if there are any institutions or something like this?

The dark environment made Su Mo tense, his pores all over his body opened and his steps were slow.

Always respond with awe for the unknown!

There is only one life, and if you lose it, you will have nothing.

Especially when Su Mo had just experienced a nuclear missile incident and was at the center of the explosion, at that moment, he felt so small that he felt scared for the first time.

It’s not that Su Mo is afraid of death, but what should Yan Jiuxi do if he dies? What should my mother do?

He is not alone!

This led to Su Mo's current mentality changing quietly without realizing it.

No matter what, he must ensure his own safety. This is responsible for life and even more responsible for those who love him.

Step by step...

Every step he took, Su Mo would write it down in his heart.

As time passed by minute by minute, 343 steps had been taken. Although his steps were very small, he had walked more than 100 meters.

But before coming in, Su Mo carefully observed the metal house. The house was a square, with a length and width of only about twenty meters, and he could feel that he had absolutely no turns.

What's going on?

"boom--"

Just when Su Mo was confused, a light suddenly appeared in front of him, and then strange sounds sounded one after another. White lights lit up above the metal channel, instantly illuminating the entire metal channel, just like daylight.

Su Mo looked forward and still didn't see the end of the passage, and a strange feeling rose in his heart.

"Xiao Xiaomo, why do you feel like this road is endless?"

"How big is this house? How can the passage be so long?"

Su Mo swallowed his saliva and asked in his heart: "Did you think I'm trapped in the mechanism?"

This phenomenon is very similar to the rumored ghost hitting the wall, but through the development of technology in recent years, the principle of ghost hitting the wall has long been studied.

In summary, the essence of biological movement is circular movement.

Without a target, any creature's instinctive movement is circumference.

Why?

Because there are subtle differences in the body structure of a creature, such as the bird's wings, the strength of the wings and the degree of muscle development, there are also differences in the length and strength of the two legs of a person.

The distance taken in this way will also be different. For example, the distance taken by the left leg is long and the distance taken by the right leg is short. After accumulating, it will definitely be a big circle, and the same is true for other creatures.

The reason why humans can maintain linear motion is because they are constantly correcting the direction with their eyes, that is, the brain is doing positioning and corrections, and constantly correcting the gap, so they become straight lines.

When you encounter a ghost hitting a wall, you must have lost your sense of direction, and in layman's terms, you are lost.

The correction function of the eyes and brain is paralyzed in a short period of time, or gives chaotic correction signals, making you feel like you are walking in a straight line, but in fact you are walking in an instinct, and what you walk out must be a circle.

Su Mo understood this truth, and he was sure that he had never lost his way at this moment.

Since entering the passage, his spirit has been tense, afraid that he will fall into an unknown mechanism, so he is very careful.

Moreover, with his current mental power, nothing can disturb his mind and thus affect the judgment of his brain.

Of course, there may be such means, but Su Mo does not believe that a first-level civilization can do this, so he guessed that he might have fallen into some unknown mechanism.

After all, he has no idea about the technological development of first-level civilizations.

Unable to figure it out, Su Mo did not continue to move forward.

At this time, it is better to ask Xiaoxiaomo for advice. If you have a system plug-in, of course you must make good use of it.

"Just just walk forward with confidence and boldness."

Xiaoxiaomo's voice sounded: "This is not a mechanism, it is just a skill in using space folding."

“Space folding?”

Hearing these four words, Su Mo's pupils couldn't help but shrink, and his voice slightly changed: "Has the first-level civilization mastered the space technology?"

At this moment, his heart was overturned and endless shock came.

Space technology?

This is an unknown field for the current human civilization.

Not to mention the superficial and fur, it is impossible to touch. According to the current development speed of human technology, it will not be able to reach the field of space technology for at least a hundred years.

In Su Mo's opinion, the space technology reported on the news is completely sold by sheep, and even he does not have the courage to enter the field of space technology.

Although Su Mo already has a certain foundation, he still has some clues in his heart, so he has never made any attempt.

Because of this, I feel so surprised when I hear the four words "Space Folding".

Xiaoxiaomo: "That's not true. Even for advanced civilizations, space technology is an unknown field, and it is carefully explored."

"The first-level civilization is already very good at mastering space folding, but space folding is only the most obvious technology in the space field, so the host should not be too surprised."

After listening to Xiao Xiaomo's explanation, Su Mo nodded slightly and asked, "Is it possible for that level of civilization to use space technology on weapons?"

The reason why I asked this question was because of his dream.

This incident has always been hidden deep in Su Mo's heart and has never disappeared.

He responded with deep awe for the scenes in his dreams, which is also the main reason why he has been doing research recently and always unknowingly making various weapons.

In his subconscious, he felt an unprecedented sense of crisis.

If space technology is used on weapons, it will be extremely terrifying!

If a first-level civilization can achieve this level, once an alien civilization invades, then...

Human beings will be in a desperate situation!!!
