After seeing those old Chinese doctors off, the world finally calmed down.

"Okay, let's go in! According to the data measured just now, there is no toxic gas in the tunnel, so you don't need to wear a gas mask anymore, which is inconvenient." Professor Fang said.

Everyone entered the tunnel again, and the fresh air inside was replaced, and everyone felt much more comfortable.

"This is a starry sky map, it's really rare in the tomb!" Hong Tianbao said. A door in front of him had to crack a seemingly complicated starry sky map.

"Many things in this tomb are unprecedented. The first level just now was Hua Tuo's relics. I really don't know what kind of treasures will appear in the next level." Professor Fang was not a play with antiques, but he was still looking forward. This also shows that Cao Cao's plan is indeed amazing. Even Professor Fang couldn't help but crack it forward, let alone others.

Chu Jiaqiang smiled. Of course he knew the treasure inside. They were two divine weapons, namely the Yitian Sword and the Qinghong Sword. Seeing this, Hong Tianbao felt that Cao Cao was extremely stupid. Both of these swords were his swords. Isn’t it arousing doubts about his existence?

The Sword of the Heavenly Sword has existed since ancient times, but it was not created by Guo Jing and Huang Rong. The sword worn by Cao Cao during the Three Kingdoms was named Yitian. It is extremely sharp and has become the name of the Sword. Li Bai, a poet of a generation, also admired him: "How can I get the Sword of the Heavenly Sword and slash the long whale across the sea?"

In the Yuan Dynasty, the Heavenly Resurrection reappeared, and the spirit was still moving. Before she was unsheathed, the coral sand stick was broken, and the sound was like a crack of paper, which was coveted. However, unfortunately, it fell into the hands of the world's most perverted Master Miejue. The pearl was cast into the darkness, dyed many heroic blood, and cut off the souls of countless patriots. The deep evil was that it was named the defeat of the martial arts world.

The ancient divine weapon, the Heavenly Sword and the Green Sword, are called "Peerless Double Swords", and are both owned by Cao Cao. "The Romance of the Three Kingdoms" says that Cao Cao used the Heavenly Sword to conquer the power, and the Green Sword to kill people.

Among them, the "Yingtian Sword" is Cao Cao's carry sword. The "Three Kingdoms" records that "Taizu thought he was willing to be Zhuo's life and suspected that he wanted to do so. He killed eight people at night with his hand sword", and used this "Yingtian Sword". Since then, Cao Cao's famous allusion of "I would rather let others down than let others down" is also left behind.

The Qinghong Sword has the word "Qinghong" embedded in gold on the hilt of the sword. It is said that the iron is as sharp as mud. Cao Cao ordered Xiahou En to admire this sword, and later it was taken away by Zhao Yun on Changbanpo. But at some point, Cao Cao got it back.

"Professor Fang, do you see the mystery of this starry sky map? We have never seen such a picture and don't know how to crack it." Expert Li said.

Professor Fang frowned and pondered. He seemed to have seen this starry sky map somewhere.

"I think about it. It seems to be a bit of an impression. Strange. I remember it seems to be the Night Star Map that Zhuge Liang once deduced, but I used to read it as a sub-book, and this is the full version. It is said that this Night Star Map is unpredictable, but it is mainly to firmly grasp the Big Dipper. The brightest star under the Big Dipper is the Imperial Star, which is also the key to the Array Map." Professor Fang said.

He didn't speak anymore, and then looked carefully. He hoped to find the key imperial star from this picture. Based on the broken books I have read before, it is not difficult to find the Big Dipper Star. But you still have a lot of work to do if you really find the most critical imperial star.

Professor Fang searched for half an hour and everyone was tired of standing. But they still had no idea.

"No! Why is this happening?" Professor Fang said to himself.

"Teacher, what's wrong?" Hong Tianbao asked.

"In theory, the imperial star is around the Big Dipper, and the distance is the same as the seven stars. This position should not be difficult to find. Only three positions agree with this requirement, but I have carefully paid attention to all three positions, and there is no existence of the imperial star." Professor Fang said his own difficulties.

"Will this be hidden?" Hong Tianbao immediately reminded.

"Hide it?" Professor Fang's eyes lit up and he clapped his hands last: "Yes. There is such a possibility." After saying that, he began to study the surface of the starry sky map again to see if it was coated with hiding substances.

"It's the legendary hidden stone divine water. No wonder, no wonder!" Professor Fang was a little excited. It was another legendary thing. He then shouted to the back: "Come on a bowl of stone slurry quickly. Use clear oil to melt it, heat it a little, and it's about fifty degrees."

The person behind was ready immediately, and Hong Tianbao asked: "What is Hidden Stone Divine Water?"

Professor Fang wiped his beard and was in a very good mood. He explained with a smile: "That is a legend. I have seen its introduction in an ancient book, but I didn't take it seriously at that time. I just saw the model of this starry sky map and touched its surface with my hands, and then I remembered this."

He paused for a while, and then explained: "Legendary: It can hide the relief engraved on the rock, which makes people unable to see clearly, but can be touched. It is very magical. If you touch it here, is there a convex point? If you guess correctly, this is the Emperor Star. Haha! This is a very magical invention in the Han Dynasty. Unfortunately, the formula of the so-called hidden stone divine water has not been passed down. Even the records of this invention are very rare. Only some ancient books may mention a sentence or two, but there is no specific basis."

The archaeological experts suddenly widened their eyes. There was such a magical thing. It was incredible that they once again felt the legendary invention of Chinese ancestors.

The things were ready soon, and Professor Fang asked someone to start shooting and recorded the magical changes for a while.

He applied the bowl of mixed oil hot stone slurry in his hand on the starry sky map. More night stars appeared in the already complex starry sky map, one of which was the largest appeared at the corner of the Big Dipper. The Big Dipper was like escorting this giant star, guarding the side, and the other stars were circling along the so-called imperial star.

"It is worthy of being the Emperor Star, and he is the leader of the Fan Star!" Professor Fang said.

He pressed the Emperor Star with his hand, and the Emperor Star immediately fell into it. At this time, a crackling sound came from inside. Everyone knew that the stone door was about to be opened.

"Don't rush in later, maybe there's something incredible." Professor Fang said just in case, and no one dared to be arrogant. After all, I almost experienced several deaths before, and I was dancing on a sharp knife, so I had to be careful.

Hong Tianbao knew that there were dense swords hidden under the passage. As long as everyone walked to the middle and touched the mechanism in the middle, all the swords would be inserted. They were really immortal and were disabled.

The stone gate was opened, and there seemed to be no danger inside. There was a Tai Chi fish on the ground in the middle of the passage. This Tai Chi fish is where the mechanism is. As long as people with curiosity are unable to help touching it, they will die.
