How can I bow my head and serve the powerful officials?

That’s all?

Xie Chengze looked at Zhang Yuheng again without giving up.

Zhang Yuheng shook his head, indicating that these were all he had seen.

Xie Chengze had no choice but to give up and did not continue asking questions. Instead, he tapped his chin and fell into deep thought.

After a long moment, he reached out and put his arms around their shoulders.

"Aren't you... curious?"

Zhang Yuheng: …

Su Qinghe: ...

Su Qinghe blinked, "Your Highness is curious?"

Xie Chengze nodded quickly.

"Then..." Su Qinghe thought for a moment, "To open the secret door, we need two keys. If we can't steal them, we can only try to crack the secret door mechanism ourselves."

Zhang Yuheng, who was standing aside, glanced at Su Qinghe with horror again.

Brother Su Xian?!

That day, I just stood in front of the secret door and threatened you on purpose, but you scared me so much that I immediately gave up the idea of ​​spying on Tianyu's secrets. How come now that the Second Prince has nodded his head, you have revealed all those things?

Have you even thought about "stealing"?

Are you still the same Su Xian brother I know? !

Xie Chengze still didn't notice Zhang Yuheng's shock. He excitedly pulled Su Qinghe's arm and couldn't help but said happily, "Can you still crack the mechanism? So amazing? You are worthy of being you, Brother Qinghe!"

The sound of "Brother Qinghe" was like turning on some mysterious switch. Zhang Yuheng could see Su Qinghe's ears and cheeks quickly turn red. Then, this usually gentle and reserved brother Su Xian began to whisper shyly, "Your Highness, I will try my best."

Brother Su Xian!

Don't try too hard!

It’s not good for us to do this!

……

Although he was screaming like this in his heart, Zhang Yuheng still stood honestly in front of the secret door in the middle of the night.

He is just a dumb man who is powerless. If Guo Tiling asked who started this, he would say he was forced to do it.

Zhang Yuheng, a tall and sturdy man, thought to himself with confidence.

In front of the secret door, Su Qinghe took out the homemade tool he usually used, lay on the secret door and inserted the tool into the keyhole to listen for the sound, while Zhang Yuheng and Xie Chengze stood on wooden chairs, covering the bell hanging in front of the secret door with their hands to prevent it from making any sound and waking up his colleagues in the Astronomical Monitoring Department who had fallen asleep.

"What happened?" Xie Chengze asked.

Su Qinghe raised his eyes slightly upon hearing that and gave him a calming look. Then he pulled out the lock-breaking tools, turned around and fiddled with the toolbox for a while, and finally picked up two pieces of wood and used a knife to carve out a shape.

He cleaned the splinters from the wood with a very obsessive-compulsive disorder, brushed lubricant on the surface, then inserted it into the two keyholes and twisted it at the same time.

"Click."

The mechanism lock of the secret door opened.

Su Qinghe glanced at Xie Chengze and Zhang Yuheng, then raised his hand and gently pushed the door open.

The string connected to the bell began to shake as the door opened. Fortunately, two people were holding it, so no sound was made. When the bell string stopped moving, Xie Chengze and Zhang Yuheng carefully let go of their hands and jumped off the wooden chair.

Xie Chengze carefully picked up the wooden chair and placed it in front of the opened secret door to prevent it from being accidentally closed and preventing them from noticing anything unusual.

Zhang Yuheng followed suit and placed another chair in front of another secret door.

Then, looking at the altar inside, the three of them looked at each other, took a deep breath and walked in.

This inner room is very simple, with only an altar and a row of bookshelves against the wall, on which are placed the existing records of divine decrees from previous years.

As for the center of the inner room, there was a huge, slightly concave round pit. The bottom of the pit was flat, and there were very complicated black rune holes carved on it, like some kind of magic circle. For some reason, Xie Chengze felt an extremely suffocating and heavy feeling pressing on him just by looking at it.

He quickly looked away, and his body and mind finally relaxed.

His eyes swept across the row of bookshelves on the wall and finally fell on the altar. The stone table on the altar looked like a podium in a modern classroom, with high baffles on both sides. Therefore, from outside the door, one could not get a glimpse of Tianyu's appearance.

And Tianyu was enshrined there.

It looks like a book.

It seems like an ordinary book.

Xie Chengze stepped forward and stretched out his hand to touch the book, but suddenly he felt a pain in his fingertips, as if he was cut by an invisible thread, and blood oozed out instantly.

He couldn't help but hiss softly and withdrew his hand.

"Your Highness!" Su Qinghe exclaimed in a low voice when he saw that he was injured, and quickly took out an embroidered handkerchief from his arms and wrapped it around Xie Chengze's finger.

“It’s okay.” Xie Chengze shook his head and looked up again. Due to the dim light in the inner room, he could not see clearly that there were countless tiny silk threads hanging around the Book of Heaven’s Revelation. Together, they looked like a “holy hand” turning the pages of the Book of Heaven’s Revelation, tightly connecting each page of the Book of Heaven’s Revelation.

Xie Chengze tried to find the source of the silk thread, but it was not clear.

What is the principle of this?

This greatly aroused the interest of this science and engineering man.

Xie Chengze hid his hands behind his sleeves, rolled up the excess fabric at the cuffs and clenched them into his fists, then, taking advantage of the little light in the room, he stuck his fists in.

He didn't dare let Zhang Yuheng and Su Qinghe light candles, for fear of burning the silk threads, thus rendering Tianyu ineffective in the future.

Although he knew the plot of this world, it was only about ten years of the plot. In the future, the Jian'an Dynasty and even other dynasties would still need Tianyu's predictions of disasters. He could not destroy this seemingly sophisticated mechanism just because of his curiosity.

Carefully passing through the silk thread, Xie Chengze touched the Book of Heaven's Decree.

The moment they touched, Xie Chengze's expression changed slightly, as if he was suddenly plunged into some kind of chaotic world.

His eyes were grey and he couldn't see or hear clearly. There was a faint fragrance of disinfectant and hand soap at the tip of his nose. He felt a very strange feeling, like his soul was being torn apart. It didn't hurt, but he felt his whole body was light and heavy, as if he had found his true body on one side, but was constantly being resisted and pulled on the other side.

"Your Highness! Your Highness, what's wrong with you!"

Noticing something strange about Xie Chengze, Su Qinghe hurriedly supported Xie Chengze's body. He was surprised to find that the silk threads seemed to be alive and had all retracted into the Book of Heaven's Revelation, so he hurriedly pulled Xie Chengze's arm back.

The moment his hand left the Book of Heaven, Xie Chengze's consciousness was pulled back, and his vision became clear again. He covered his nose in confusion, not knowing whether it was an illusion or not.

The smell of disinfectant is very similar to the smell in a hospital operating room.

Xie Chengze had appendicitis when he was a child, and his class teacher took him to undergo surgery. This was the smell he vaguely smelled.

Is it...

Could it be that in the modern world, he is being rescued in the operating room?

Is he not dead?

So can he go back and see his parents?

Xie Chengze couldn't help but tremble all over, his nose tip suddenly felt sore, and his eyes couldn't help but start to turn red.

"Your Highness? Are you okay? Don't scare me!" Seeing Xie Chengze trembling all over as if he was frightened, Su Qinghe felt so distressed that he secretly regretted that he should not have pried open the secret door, causing the Second Prince to be injured and even making the Second Prince show signs of losing his soul.

Seeing that Xie Chengze was still in a daze, Su Qinghe couldn't make up his mind, so he looked at Zhang Yuheng, "Brother Zhang Xian, what should we do? Should we find an imperial physician?"
