The ring connects the past and present, the exiled prince worships me as a god

The stone door, built of variously shaped stones, had a fist-sized gap that allowed a clear view of the other side, but no matter how hard I tried, or with any tools, I couldn't open it. It was surprisingly solid.

Looking more closely, it turns out that there is a special technique behind the arrangement of the stones.

The professor didn't let the students waste time on this. After a brief explanation, he told the students the code that the experts had spent seven days to decipher.

It turns out that by rotating the left and right stones, pressing the upper and lower stones, and then frequency-knocking on the gravel with the same pattern as the middle stone, the stone door will open directly.

Song Nian called out to Qi Yu: "Have you reached the second door?"

"Exactly. Although I encountered some difficulties, they didn't bother me."

Judging from what Qi Yu said, did he open the second door?

Song Nian curled her lips proudly. Her boyfriend was so smart.

Just as she looked up to see what was behind the second door, countless sharp swords shot towards her as if they had eyes. The professor said from above, "If it were you at this moment, you would definitely try to escape or dodge. So, students, watch out."

boom.

The surrounding walls suddenly exploded violently, and the ground beneath my feet even began to collapse.

It’s a bottomless height, and if you fall down, you will die.

The whole thing happened in the blink of an eye, less than three seconds, which is not enough time for an adult to react.

Song Nian held his breath and quickly put the ancient ring to his lips, "Can't open the second door!"

She almost screamed out loud.

Qi Yu's voice almost made her faint.

"It's too late, oops!"

Then Qi Yu's voice was never heard again.

Obviously, he was experiencing everything that Song Nian saw.

Qi Yu is very skilled and will definitely be able to dodge it.

Song Nian crossed his hands in front of his chest, as if praying.

The professor on the podium observed this and smiled indulgently, "Don't worry, everyone. Although our archaeologists have also encountered this, they are fortunately well prepared. By simply touching the mechanism here, the flying swords will stop, and the collapsed ground will recover. But the soldiers will face the even more difficult third door."

When Song Nian saw the professor enlarge the secret passage to close the mechanism, she hurriedly took out her mobile phone to take a picture and then secretly sent it to Qi Yu.

But Qi Yu had no time to watch it at this moment, and he couldn't even catch the phone that Song Nian handed to him.

In order to prevent his phone from breaking, he dodged and turned back. The sharp sword brushed past his shoulder and cut his skin, and he groaned.

At this moment, he discovered the clue on the wall. The next moment he stretched out his long arm to catch the phone, he tapped his toes lightly and touched the switch, and everything returned to normal.

"Qi Yu?"

Not getting a response from Qi Yu, Song Nian realized that he must be struggling to fight against various agencies at the moment, and he had no time to answer her call. She was causing trouble for him.

It seems that next time I find the direction of the mechanism, I have to tell him directly.

Her heart was in her throat. Song Nian didn't dare to breathe or ask. She was even more worried. Until her empty pocket suddenly sank and the phone returned to her pocket, she breathed a sigh of relief.

"Nothing, Nian'er, don't worry."

How can you not be nervous?

She was watching here, but he was actually in real danger.

She was very grateful that the class the professor arranged today could help Qi Yu, allowing her and Qi Yu to overcome difficulties together through time and space.

"Students, what are these?"

The professor's words brought Song Nian back to his senses.

In the video, the third door had no mechanism. When the stone door opened, there were rows of sculptures standing neatly and orderly in the empty room.

"The Terracotta Army?"

A classmate raised a question.

The professor smiled mysteriously and clicked the play button. Suddenly, the lifeless sculpture came alive as if it had come to life.

Their eyes were bloodshot as they attacked the door.

Song Nian and his unsuspecting classmates all shuddered unexpectedly.

These sculptures were incredibly fast, brutal, and resembled some kind of formation.

The scene of Qi Yu trapped in the center immediately appeared in Song Nian’s mind.

"Professor, what would happen if people were trapped?"

When the professor heard this, a look of sadness flashed across his face.

"I'm very sorry to tell you that we have lost a very good archaeologist here."

In other words, someone died in this level.

Someone really died.

Song Nian subconsciously held her breath. She wanted to call Qi Yu, but she knew she couldn't cause trouble for him.

The moment the stone door opened, the sculpture began to move. Qi Yu's time might be faster than hers, as there was a time difference between them.

"What then?"

How did the remaining archaeologists get through this?

Looking at the worried expressions of the students in the audience, the professor said indignantly, "That's why our country is currently vigorously developing and promoting unofficial history culture. We want more people to know about the existence of unofficial history, the sacrifices made by archaeologists, and our efforts."

The professor slid to the next clip and saw that the fierce battle scene suddenly broke out into a raging fire.

"Yes, these sculptures are actually controlled by fire."

With a snap, the professor lit a lighter.

Suddenly, a video of the archaeologists appeared on the screen.

A man threw away the lighter in his hand, and the fire instantly burned the sculpture. The moving sculptures also stopped at a speed visible to the naked eye and returned to their positions, as if nothing had happened.

"This is amazing."

someone exclaimed.

The professor nodded repeatedly.

Song Nian found a way to crack the code and asked the person next to him, "Classmate, can I borrow a lighter?"

The male classmate thought Song Nian was playing with it, so he quietly slipped the lighter to her from under the table. Song Nian quickly passed it to Qi Yu and whispered a reminder: "They are afraid of fire."

Qi Yu, who was fighting tenaciously, had already suffered minor injuries of varying degrees, but he did not give up and even ignited his fighting spirit. As he fought desperately, he listened to Song Nian's words in his mind. The next moment, he spread his palm in tacit coordination, and a lighter fell into his palm. The moment he lit it, the sculpture returned to its original position.

"What a great Beiling Tunnel."

It hides so many unimaginable mechanisms and secret techniques.

Qi Yu was extremely amazed, and at the same time he was even more amazed at Nian'er's assistance.

"Thank you, Nian'er."

When he returns to the palace, he will definitely leave a heavy mark on Nian'er's military achievements.

"Level 4, Level 5, Level 6, what do you think after watching it?"

The professor continued to play the video animation, and the students present were all motivated.

Song Nian did not join in the discussion. She whispered to Qi Yu every time she saw a dangerous place. When she heard that he had successfully passed the level, she also breathed a sigh of relief.

It’s the last level.

"This level is so dangerous!" Qi Yu said.

Song Nian was about to say, it’s okay, she’s here.

Jingle Bell.

The bell rang and the professor turned off the video animation.

"Shall we continue next class?"

Professors come and go in a hurry.

But without the video animation, Song Nian couldn't see the next journey, let alone the danger Qi Yu was in. She couldn't help her man!
