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

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

More than ten minutes passed, and the scene in the tunnel remained unchanged. In front of it was dark, hard walls on both sides, and cold tracks under your feet.

Driven by Chen Xing, the Goblin changed from walking to trot, and then to running the wolf cavalry.

But more than ten minutes passed, and the same scene was still the same.

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

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

The ancient steam train stops on the side of the platform, exactly the same as the scene when it left.

The two of them speeded up, returned to the platform, checked around, and found that they were the original place.

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

But the Seventh Princess shook her head, as if she had no clue.

"Try it again."

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

After more than ten minutes, the two ran for more than 30 kilometers. They felt that they were almost done, so they turned around. As a result, they ran for less than half a minute and 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 times, and the results were the same each time. No matter how far they ran, they could return to the train platform by turning a few hundred meters.

The situation is too strange, as if moving forward is just an illusion in my mind, they have never left the range of the platform. This also explains very well why at the beginning, Chen Xing could not feel that the wolf cavalry had run too much.

Far.

Chen Xing couldn't help but see the ghost stories he heard when he was a child. Could it be that they encountered the legendary "ghost hits the wall"?

Just as Chen Xing was thinking about it, the seventh princess who was frowning and pondering on the side suddenly raised her eyelashes and showed an active expression, "I understand!"

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

"I know what's the reason!" The Seventh Princess looked at Chen Xing, a little excited, "Do you know the reasons and characteristics of the formation of world fragments?"

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

The fragments of the world are fragments of space left when a certain world ushers in the end. They are silent in the undercurrent of time and space until one day flows into other worlds. In the case of characteristics, they are activated again.

The space fragments that flow into other worlds will gradually communicate and merge with this space.

There are two ways of fusion. The first is repulsion reaction, which is incompatible with the world, and eventually leads to an explosion in space and turns into dust to blend into this world. The second is a stable fusion, which gradually merges into this world after a long period of time.

"Then have you heard of the vase theory?" asked the Seventh Princess again.

"Vase theory?" Chen Xing asked in confusion, "What vase represents a woman's vase?" He looked at the other party, "Are you a vase?"

Vases usually refer to women who are not good at using it, with only beauty but no talent.

"You are such a bad guy." The Seventh Princess commented seriously, and then made an explanation, "The vase theory is an extension theory of the broken window theory, revealing 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 high place and falls into countless pieces on the ground, what are the patterns of the shape, size and quantity of these pieces?"

The Seventh Princess asked and answered, "The vase is an irregular object and must first break from the weak part. The high-strength part will have a high probability of forming complete fragments."

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

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

"The data shows that you have never been to elementary school." The Seventh Princess replied.

"Yes, I haven't even attended elementary school, why do I ask so many questions?" Chen Xing said angrily, "You just want to say whatever you want. Don't always ask questions, okay! Classmate Zhao, Teacher Nova

!”

"But, I think you are quite smart." The Seventh Princess turned her face, "Although you have never been to elementary school, you are more cunning than many scholars."

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

"You are very good at chatting," he said.

"Thank you for your praise!" The Seventh Princess nodded and gave a gift.

Then, she continued to explain the vase theory.

The intensity of space is determined by the energy contained in the space. The two are proportional, that is, the higher the energy intensity, the greater the total amount, the stronger the space.

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

Without these powerful energy matters, the space might have been broken long ago. At the same time, if fragments of a world are mined and all energy matters are taken away, the speed of space fusion will increase in geometric ranges.

This railway station is completely preserved and has a stable spatial structure, which is bound to be because of some powerful substances containing huge energy that make this space independently separate from the originally destructive world.

Speaking of this, the Seventh Princess slowly turned her head and looked at the ancient steam train.

Chen Xing was instantly blessed and said, "What do you mean is that the main reason for forming this space is that infinite steam engine?"

"The infinite steam engine is the energy core that supports the existence of this space." He learned from it, "because the core was removed, the space fell into chaos, so no matter how we walked, we could not leave the station."

"You are so smart!" The Seventh Princess looked surprised. Because the information in the database told her that if she wants to gain the favor of this man and reduce the risk of joint action, she should praise the other party more.

She then continued to explain, “According to the vase theory, the greater the correlation between space and energy core, the more complete the preservation.”

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

"So what?" Chen Xing couldn't understand again, "What do you mean is that you have to install the infinite steam engine back so that the space will return to normal?"

"Not necessarily." The Seventh Princess pointed to the steam train, "If we could start it, maybe we could get to the next stop."

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

"This thing is so heavy, how can I start it?"

The Seventh Princess did not answer, but walked forward, paused gently, and countless parts flew out of the void, assembled into thick steam armor on her petite body.

She raised her two giant mechanical gloves, slapped her heavily, grabbed the locomotive, pulled her lunge with her feet, and pushed her forward with force.

"Millions of steam power!"

In an instant, six air columns behind them soared into the sky, the entire station vibrated, the rust on the train slid down, and the metal structures rubbed and collided with each other, making a huge sound.

“Crunch, crunch!”

"Boom..."

Chen Xing couldn't help but widen his eyes. This power was so amazing that it was not like a creature on earth. His seemingly petite body burst out with divine power.

"drink!"
Chapter completed!
