Three days later, Wang Shanhai led Wang Yachen and a handsome young man to the residence of Zheng Dong and Zhang Wenqi.

The first thing that catches your eye is the leftovers of rice all over the floor, the porcelain bowls are scattered, and there is a broken wine jar, and then two people lying asleep in the courtyard.

“……”

"Zheng Dong!" Wang Yachen's willow eyebrows were upside down, "Wake up!" Do you have the kind of inspirer you have? ”

"Well, pinch ......" Zheng Dong pursed his lips and turned over, his little face buckled in the bowl.

"Well, the Inspirer." Wang Shanhai coughed lightly.

"Wow!" Zheng Dong suddenly jumped up, and then rushed to the house under the surprised eyes of everyone.

There was the sound of washing and changing clothes.

Then, a handsome young man came out of the house.

Zhang Wenqi had just been woken up, rubbed his sleepy eyes, glanced at Zheng Dong, and muttered, "Who are you?" ”

"Am I so handsome? You don't even recognize it? Zheng Dong said indifferently.

"Huh? Zheng Dong? Why do you ......" Zhang Wenqi reacted, and then noticed the three people behind him, and the next moment, like Zheng Dong, rushed into the house, and the sound of changing clothes and washing came out.

Then, an elegant young man came out of the house.

Wang Yachen and the three: "......"

"Is it time?" Zheng Dong is colorful.

Wang Shanhai replied: "Yes, the obstacles around the secret room have been basically cleared, and you can enter." ”

"Obstacles?"

"Yes, in order to prevent the destruction of the Hymn Cult and the Secret of Praise from being captured, we have hidden the secret room in a very secret place, and many obstacles have been set up."

"That's right. Let's go, hey, who is this big brother? Zheng Dong looked at the handsome young man.

He stepped forward, bowed slightly, and said, "My name is Hao Feng, and I am the captain of the village's guards. ”

"It's also the little girl's fiancé," Wang Shanhai said with a smile, Wang Yachen blushed when he heard this, "Hao Feng is the only person in the village who is familiar with the secret room road, and he will lead us this time." ”

"Okay." Zheng Dong nodded.

Together, they walked deep into the mountains, following a winding path to the dense forest.

Birds and insects flew, the sun was moist, stepping through the thick fallen leaves on the ground, and several people saw the entrance of a pitch-black hole under a giant tree in front of them.

"Hiding here?" Zhang Wenqi asked.

"It's a labyrinth." Hao Feng's expression was solemn, "After the construction was completed thousands of years ago, only a very few people from each generation of guardians have come. ”

"What about obstacles?"

"It's been cleared, I went on a trip myself, and wiped out the traps and traps."

"Shall we go in then?" Zheng Dong's voice was calm, but everyone heard a few inexplicable tastes from it.

There is nervousness, anticipation, and a little fear.

"The Inspirer?" Wang Shanhai took a step forward, "Are you ready?" ”

Zheng Dong was silent for a while and asked, "Is this the case with the previous generation of enlighteners?" ”

"I don't know, but I will clarify everything from a certain opportunity, and then through some things, I will promote the progress of the world." Wang Shanhai said, "There are more details, and we don't know about them. ”

"Don't you know the truth?"

"I know a little."

"Can you tell me?"

"Yes." Wang Shanhai nodded.

"What's going on with those four paintings? Has the Enlightener always been a person? ”

"......" Wang Shanhai looked at Zheng Dong, whose eyes flashed, "I don't know." ”

"All my information comes from the writings of my ancestors." Wang Shanhai said, "But I know that this secret room was built by the previous enlightener under the guidance of the preachers at that time. ”

"The last Inspirer? The father of the Industrial Revolution?! ”

"Yes. One day he suddenly appeared in front of the previous group of heralds, told them to build a secret room, store something, and then flew into the sky again. ”

Zheng Dong looked at the dark entrance of the cave, and the hesitation in his heart gradually faded.

"Even if it's the same person, I'm not afraid, I believe that the previous generation of me, the reason for doing this."

Zheng Dong took a step forward and walked forward.

"Let's go and reveal the truth!"

Several people walked into the dark crypt together.

Hao Feng walked to the front to lead the way, and Wang Yachen lit a torch to illuminate the flat but ash-covered ground.

The firelight danced, reflecting Hao Feng's suddenly surprised face.

"No, the passage has changed!"

"What?!" The crowd screamed.

"It's okay," Zheng Dong's clear voice sounded, revealing calmness and determination, he looked at the darkness in front of him, and said, "Deliberately designed like this, if Hao Feng alone can clear all the obstacles, others can also come in and spend their energy." ”

"I feel something calling me," Zheng Dong walked forward, "it tells me a lot of information......

"Follow me!" Zheng Dong's eyes froze.

"Ancient organs...... Wang Shanhai sighed.

Everyone followed Zheng Dong and went deep into the crypt, inadvertently turning through multiple corners.

"No, we're going around in circles!" Zhang Wenqi shouted.

The crowd stopped, and only the light of the fire flickered in the darkness.

"yes, we're going around in circles." Zheng Dong bit his lip and frowned.

"Keep going and see? How come I don't feel like I'm going around in circles? Wang Yachen suggested.

"It's really going around in circles! You shine a torch on the wall. Zhang Wenqi pointed to a wall.

Wang Yachen put the torch over.

A faint indenture on the wall, fist-shaped.

"Keep walking." Wang Shanhai stared at the fist print and said.

Zheng Dong put the small fist up, one size smaller, but the silhouette fit perfectly.

The crowd did not speak again and went on.

After a while, everyone saw the fist mark again.

"We've been going down!" Hao Feng's face was solemn.

"No, it's still going up!" Wang Yachen said.

The crypt was dark and silent.

"Can we still find our way out?" Zhang Wenqi said, "Go back and try? ”

"No need." Zheng Dong said suddenly, his back to everyone, and a blue glimmer overflowed on his face.

"The Inspirer?!"

"Zheng Dong?!"

Zheng Dong turned his head, and the blue light in his eyes flashed.

"It's the Penrose Ladder."

"Penrose Steps?"

"Yes, I remembered something," Zheng Dong said, "similar to the Möbius ring, which only exists in a space one dimension higher than its structure. ”

"The Möbius ring can realize the crossing of the two-dimensional plane in three-dimensional space, similar to a two-dimensional note, which can be rotated to construct a three-dimensional object, so that the object on it can reach the other side of the paper without passing through the edge."

The voice was very peaceful, and Zheng Dong looked at everyone with a confused expression: "I didn't say it." ”

"The Penrose Staircase is the same way, it is an infinite loop of steps up or down, which can only be experienced through optical illusions in three-dimensional space, and can only be realized in four-dimensional space."

Everyone looked at Zheng Dong.

"I really didn't say it, my voice is so ugly?" Zheng Dong spread his hands.

"We know it wasn't you who said it, the question is, what does this voice say?" Zhang Wenqi said, suddenly patted his head, his eyes lit up, as if he understood something, "Oh! Talking about such a thing! ”

The rest of the people still didn't understand, and the focus at the moment was on this inexplicable voice, and they all frowned.

"Master, can't this four-dimensional object remind you of something?"

"Master?" Zheng Dong muttered, and everyone was surprised.

"I'm the four-dimensional plane system you left here, and you will be tracked with me, so you put me here." The voice continued.

"What do you mean?"

"Understood, come on, master, I'll activate your memory!"

The next moment, a blue light suddenly lit up in the black passage, and everyone closed their eyes, quite uncomfortable.

When the light softened, everyone saw themselves in a blue crystal tunnel.

There are no gaps in the passage, as if they were made in perfect fit, and there is not a trace of dust on them.

"Where are we?" Zhang Wenqi said.

"We're in four-dimensional space." Zheng Dong spoke, staring at a blue light cluster that appeared in front of him at some point.

"It's not a four-dimensional space, it's just a four-dimensional crack that has passed through, which is the discharge port inside the system." The source of the sound was determined, and it was the blue light cluster.

Including Zheng Dong, they were all puzzled.

"Master, I'm here to show you the memories of your first four awakenings." The blue light cluster said gently.

When the words fell, a dazzling light suddenly appeared in front of everyone's eyes. Then everyone felt like they were being swallowed by the light.

When they opened their eyes again, they were in an infinite cosmic space.

In front of it, there were groups of huge oval warships.

The tail of the battleship glowed with dazzling light, like a bright star.
