In the huge arched passage, the fire was bright. Two rows of goblins held torches and explored the cave wall.

Chen Xing and the Seventh Princess followed behind and walked along the track.

Ten minutes passed, and the scene in the tunnel remained unchanged. There was bottomless darkness ahead, hard walls on both sides, and icy tracks underfoot.

Driven by Chen Xing, the goblin changed from walking to trotting, and then to running like a wolf cavalry.

But ten minutes later, it was still the same scene.

For safety reasons, the two decided to return the same way they came. But at this moment, something incredible happened!

The two walked back a few hundred meters and saw the train platform.

The ancient steam train stopped at the edge of the platform, exactly the same as when it left.

The two of them quickened their pace and returned to the platform. They checked around and found that they were in the original place.

"What's going on? We've obviously gone a long way!" Chen Xing looked at the Seventh Princess and pinned his answer on the mastermind's huge knowledge base.

But I saw the seventh princess shaking her head, as if she had no clue.

"Try again."

The two returned to the train tunnel. In order to improve efficiency, Nova summoned the Phantom Feathered Spirit Snake to explore the path ahead, while Chen Xing summoned the White Wolf King, took the Seventh Princess, and ran at full speed on the railway track.

After more than ten minutes, the two of them ran more than 30 kilometers. When they felt that they were almost there, they turned back, and after running for less than half a minute, they returned to the train platform again.

"hiss……"

Looking at the familiar scene in front of him, Chen Xing couldn't help but take a breath.

Next, the two tried several more times, but the result was the same every time. No matter how far they ran, they could just turn around and return to the train platform a few hundred meters away.

The situation is too weird. It seems that moving forward is just an illusion in the mind, and they have never left the range of the platform. This also explains well why at the beginning, Chen Xing could not feel the Wolf Cavalry running out much.

Far.

Chen Xing's mind couldn't help but think of the ghost stories he heard when he was a child. Could it be that they had encountered the legendary "ghost breaking the wall"!

Just when Chen Xing was thinking wildly, the Seventh Princess, who was frowning in thought, suddenly raised her eyelashes and showed an active expression, "I know!"

"What do you know?" Chen Xing asked subconsciously.

"I know the reason!" The seventh princess looked at Chen Xing, slightly excited, "Do you know the reasons and characteristics of the world fragments?"

"I know a little bit..." Chen Xing nodded.

World Fragment is when a world comes to an end

The space fragments left behind. They remain silent in the undercurrent of time and space until one day they flow into other worlds. Under special circumstances, they are activated again.

The space debris that flows to other worlds will gradually communicate and integrate with this space.

There are two ways of fusion. The first is a rejection reaction, which is incompatible with this world, eventually causing space explosion and turning into dust to merge into this world. The second is stable fusion, which gradually merges into this world over a long period of time.

"Then have you heard of the vase theory?" the seventh princess asked again.

"Vase theory?" Chen Xing asked doubtfully, "What vase, does it represent a woman's vase?" He looked at the other person, "Are you a vase?"

A vase usually refers to a woman who is of no use but has no beauty and no talent.

"You are such a bad guy." The Seventh Princess commented seriously, and then explained, "The vase theory is an extension of the broken window theory. It reveals the formation process and internal laws of the world's fragments through the movement and changes of the vase..."

"When a vase falls from a height and breaks into countless pieces on the ground, what is the pattern in the shape, size and number of these pieces?"

The seventh princess asked herself and answered, "The vase is an irregular object. It will inevitably break from the weakest part first, and the strong part will most likely form complete fragments."

"Do you know what factors determine the weakness and strength of space?" the seventh princess asked, like a little teacher teaching students.

"This classmate..." Chen Xing patted the other person on the shoulder, "Do you know my academic qualifications?"

"The data shows that you have not attended elementary school." The seventh princess replied.

"Yeah, I didn't even go to elementary school, why are you asking me so many questions?" Chen Xing said angrily, "Just say what you want, don't keep asking questions, okay! Classmate Zhao, Teacher Nova

!”

"But, I think you are quite smart." The seventh princess turned her face sideways, "Although you have not gone to elementary school, you are more cunning than many scholars."

After hearing this, Chen Xing smiled and said, "No one told you..."

"You're good at chatting," he said.

"Thank you for the compliment!" The Seventh Princess nodded in return.

Then, she continued to explain the vase theory.

The intensity of space is determined by the energy contained within the space. There is a direct proportional relationship between the two, that is to say, the higher the energy intensity, the greater the total amount, and the stronger the space.

This is also the reason why undercurrent relics can be found in world fragments.

Without the support of these powerful energy substances, space might have been shattered long ago.

At the same time, if all the fragments of a world are mined and all energy-containing materials are taken away, the speed of space fusion will increase geometrically.

This train station is completely preserved and has a stable spatial structure. It must be because of some powerful matter containing huge energy that made this space independently separate from the originally destroyed world.

Having said this, the seventh princess slowly turned her head and looked at the ancient steam train.

Chen Xing instantly felt blessed and said, "You mean, the main reason for the formation of this space is the infinite steam engine?"

"The infinite steam engine is the energy core that supports the existence of this space." He drew inferences. "Because the core was removed, the space fell into chaos, so no matter how we walked, we couldn't leave the station."

"You are so smart!" The seventh princess looked surprised. Because the information in the database told her that if she wanted to win the favor of this man and reduce the risk of joint actions, she should praise him more.

Then she went on to explain, "According to the vase theory, the greater the correlation between the space and the energy core, the more complete the preservation."

"The extension of the infinite steam engine is the train, the extension of the train is the rail, the extension of the rail is the platform and tunnel..."

"So?" Chen Xing was confused again, "You mean, the infinite steam engine must be put back in order for the space to return to normal?"

"Not necessarily." The seventh princess pointed to the steam train, "If we can start it, maybe we can reach the next stop."

Chen Xing walked over and put his foot on the locomotive. He didn't move at all, not even making a sound. He just felt as solid as a mountain and as solid as a rock.

"This thing is so heavy, how do you move it?"

The seventh princess did not answer, but stepped forward. With a slight pause, countless parts flew out of the void and were assembled into thick steam armor on her petite body.

I saw her lifting two giant mechanical gloves, slapping them hard, grabbing the locomotive, stretching her legs apart, and pushing forward with all her strength.

"Millions of steam power!"

In an instant, six air pillars shot up into the sky from behind, and the entire station shook. The rust on the train slid off one after another, and the metal structures rubbed and collided with each other, making a loud noise.

[To be honest, I have been using Yeguo to read and catch up on books recently. I can switch sources and read aloud with many sounds. www. Android and Apple are available.]

"Crunch, crunch!"

"Rumble, rumble..."

Chen Xing's eyes widened involuntarily. This kind of power was so amazing. It didn't look like a human creation at all. It seemed like a petite body, but it exploded with overwhelming divine power.

"drink!"
