"Time is up, let's go!"

Three hundred meters, three hundred meters...

Keep going down, Mu Feng, Tie Meng and He Qiang spent nearly ten hours, and almost three thousand meters lowered. The big crack seemed to have no bottom.

When it reaches about one thousand meters, the temperature rises much slower.

At two thousand meters, the temperature outside had dropped to about minus fifty degrees. This temperature could be withstood for ordinary people (human physique has changed a long time ago, and the severe cold of minus fifty degrees can be withstood). Moreover, Mu Feng and the others are all ancient martial arts practitioners.

"What is this?" He Qiang suddenly exclaimed in surprise, and there was a drop of bright red liquid between his fingers.

"What's this?"

The three of them came together, and the lights on their foreheads gathered on the stone wall. Blood-red liquid oozed out of the cracks in the stone wall.

All three felt a little frightened.

In this environment, it can still exist as a liquid. Can you be an ordinary liquid?

"Is this blood?"

"The blood can still be liquid at minus fifty degrees Celsius. Besides, there is not even a ghost here, where does the blood come from?" Tie Meng said.

"There is something strange here!" Mu Feng reached out and tapped the stone wall, listened carefully, and said solemnly.

"Empty?" Tie Meng also reached out and knocked a few times, and a hint of shock appeared in Muran's eyes.

"Um."

"Do you want to go in and take a look?"

"The Star Stone is so strong, can it be broken?" Mu Feng asked.

"If there is a special wall-breaking machine, there will be no problem. Even if the Sky Star Stone is hard, it can be broken." Tie Meng explained.

Mu Feng really has a wall breaker, in the crescent space, but how do he take it out and how can he explain it?

Obviously not possible.

"Iron Master, Brother He, let's look for it. Maybe we can go in without a wall breaker." Mu Feng touched the tiny gap.

"Yes, see if there are cracks nearby, maybe we can go in."

"Look separately, the distance is not allowed to exceed fifty meters!" Tie Meng always remembers the "Three Rules".

"Yes, Iron Master."

It is said that Mu Feng has a big cheating device, which is Zhizi. Zhizi's body is just a smart program or intelligent life that produces ontological consciousness, but it can control external instruments and do things that humans cannot do.

Mu Feng has almost emptied the sixth floor laboratory of Baiqi Secret Realm, with tens of thousands of various instruments and equipment. Mu Feng has only learned a part of it in the laboratory for half a year.

The technological level of the aliens thousands of years ago is much higher than that of the entire Milky Way today. If it weren’t for the small number of aliens and the aggressive nature, they were united and wiped out by the hundreds of races, aliens would have long become the only overlord of the Milky Way.

What is certain is that the aliens are not native to the Milky Way, but they should be invaders of alien galaxies, but even the aliens who created the Zhizi themselves do not know.

However, here, Zhizi's ability is also limited. It can detect at most a position with Mufeng as the radius, about one thousand meters.

"Master, there is a crack in front of you, three hundred meters ahead of you, which can accommodate a person in..."

"Okay, I'll go over and take a look."

"Xiao Mu, what are you doing..."

"Iron Master, I saw a crack in front of me, go and take a look." Mu Feng hurriedly explained.

"Wait a minute, I'll go with you." Tie Meng quickly crawled over without saying a word.

"Iron Master, why are you guarding me like a thief?"

"I have to watch you." Tie Meng was not slow. After a while, he crossed dozens of meters and came to Mu Feng.

Mu Feng was speechless, but he could indeed feel Tie Meng's care and protection for him, which also moved him very much.

"Let's go!"

Tie Meng greeted He Qiang, and the three of them crawled in the direction Mu Feng said.

The distance of three hundred meters took nearly five minutes for the three people to arrive. Tomoko did not lie to him. There was really a crack there, and only one person was allowed to enter.

"I'll come first." Tie Meng stood in front of Mu Feng with voluntary action and entered the crack first. "You two will make sure you come in safely after I go in."

Mu Feng and He Qiang looked at each other and smiled helplessly.

After waiting for about ten minutes, Tie Meng's voice came out from inside. At this speed, Tie Meng advanced at least hundreds of meters.

Mu Feng and He Qiang also entered the crack, one after another,

Because Tie Meng took the lead and opened up the road, Mu Feng and He Qiang walked faster. Three or five minutes later, they saw Tie Meng in front of him.

At this time, the gap between the cracks became much larger, and at least two people could be allowed to move forward.

There is wind!

This shows that the crack leads to the outside and the wind blows out from the inside. This discovery allows the three of them to continue moving forward and move forward for about half an hour.

Suddenly there was no way ahead!

A stone wall blocked the three of them.

"No, since there is no road ahead, where did the wind come from?" The three of them were a little confused and began to search around to find the source of the wind.

"This wind blows out from this stone wall!"

"Captain Mu, be joking. I believe the wind can blow out from the cracks of the stone. Maybe it will blow out from the stone. I don't believe it at all." He Qiang walked past, touched it carefully, and then put his face up to feel it.

"This, this wind really blows out of this stone..." He Qiang took a step back suddenly, pointed at the stone wall in horror and said.

"It's true that this stone wall is strange!" Tie Meng came forward, looked carefully, and confirmed.

"Iron Master, Brother He, look, although the color of this stone wall is similar to that of the Star Stone, their material is not the Star Stone at all." Mu Feng had discovered a little secret.

"Yes, this is not a star stone, but it seems that it is a material that I have never seen before." Tie Meng was more experienced after all, and soon saw some clues.

"I have never seen it before." He Qiang also approached carefully, glanced at it, and shook his head.

"Master, this is a critical stone, which is used to repair space cracks!" At this time, Zhizi's voice sounded in Mu Feng's mind.

"Critical Stone, what?" Mu Feng was stunned and asked.

"I'm not very clear. It is a very special material, between matter and dark matter, and generally exists in nebula produced after the explosion of stars!"

"The nebula of the stars exploded?" Mu Feng asked, "What's going on?"

"Tycho doesn't know either. It was because Tomoko searched for information left by aliens and found this record..." Tomoko explained.

"Repair the space cracks, can you say that there is another space behind this stone wall?" Mu Feng was startled by his speculation.

Kawa Star is just an abandoned resource star. How could such a thing exist?

"Xiao Mu, what are you talking about?"

"Iron Master, Brother He, I suspect there is a space behind this stone wall?"

"Space, are you talking about the secret realm?" Tie Meng was shocked, and his whole body was trembling with excitement.

Secret realm?

Mu Feng really didn't expect that Tie Meng reminded him that Bai Qi's Secret Realm is just a closed space. There is a critical stone to repair space cracks here, so behind the stone wall, it is entirely possible that there is a secret realm space.

Thinking of Zhizi's discovery in the Blood Buddha Treasure House, the Blood Buddha is likely to be hidden in this secret realm, but it is not surprising that it can't be found everywhere.

There is actually a secret realm space on this Kawa Star. This discovery is enough to shock the world. The human federation has discovered no more than one hundred secret realm spaces for thousands of years!

Of course, Mu Feng did not touch on these core secrets. He didn't know some things, but Tie Meng knew a little.

The top ten colleges and universities in the Human Federation all have their own secret realm spaces to cultivate their own genius students. Some of the other secret realms are in the hands of the military, and some are in powerful families.

What does it mean to have a secret space? That value is immeasurable and will make people completely crazy.

Of course, it is unknown how many secret realms like Bai Qi's Secret Realm have long been occupied by aliens and even set up a huge conspiracy.

The rapid development of human civilization is related to the discovery of these secret realms. While the aliens conspired to plot against humans, they also objectively helped the progress and development of human science and technology.

Prehistoric civilization technology integrates with modern human civilization to form a new civilization system, and the Milky Way has also developed in this way.

This has a feeling of planting trees by predecessors and enjoying the shade by later generations.

After all, the longest history of the hundreds of races in the Milky Way is only hundreds of millions of years, and the universe has been born for more than 4.6 billion years. Who knows exactly what happened in the previous 4.5 billion years?

"Xiao Mu, Xiao He, only the three of us know about this matter. We cannot mention it to four people, otherwise there will be a huge disaster!" Tie Meng said solemnly.

"If it is really a secret space, what should we do?"

“…”

"What I worry about is that Blood Buddha may have known about it for a long time. After all, he has been on Kawa Star for so many years, and he is even in this secret space." Mu Feng said.

The three of them were silent.

"Why is this critical stone so hard? I want to knock on it and take it back to study it!" He Qiang picked up the mining hammer and smashed it hard on the stone wall. He found that there was a wave of energy fluctuation on the stone wall. The hammer in his hand was almost hit by a recoil.

"Restoration protection is indeed a boundary wall, but this space seems to be expanding to the outside world, and the gap we came here should be stretched open by it."

"Well, judging from the contact between the boundary wall and the star stone, there is really this possibility." Mu Feng walked over, carefully observed the place he contacted, and agreed with Tie Meng's judgment.

"How come this world wall leaks..." He Qiang murmured.

Mu Feng and Tie Meng couldn't answer this question because it was beyond their cognition.

"Go back first."

"If the Blood Buddha is in the secret realm, can he enter, can we also enter?" Mu Feng looked at Tie Meng and He Qiang with burning eyes.

"But where is this entrance, how do we know?"

"The boundary walls here are all leaking, so there must be more leaking places. Let's look for them and maybe find a place that allows us to enter the secret space."

"Yes, the bigger the crack, the bigger the air leakage. Why can't this boundary wall be without cracks?"

"Yes, there is still time anyway, so let's continue to look."
