Gu Chenzhou used his mental power to try hard to outline the form and position of the gold element within the earth element. Within a moment, he broke out in sweat and became dizzy, shaking on the spot.

Ding Yuanyi patted Gu Chenzhou's back gently and looked back at Jiang Wutu in the crowd.

Seeing this, Jiang Wutu hurriedly stepped forward and stood on the other side of Gu Chenzhou.

Lei Chunming adopted the safest plan based on the opinions of Ji Yunyang and Li Cheng.

Gu Chenzhou let go of his ears.

He heard the sound of the small metal piece sealing the crack in the door moving as Lei Chunming moved.

Controlling the metallic power he had just mastered, he felt that a small metal piece that originally sealed the crack of the door moved to the side of the door under Lei Chunming's operation.

This High Level mechanic is really talented.

Zhang Weiguo stood next to Lei Chunming, with the towel in his hand helping Lei Chunming wipe the sweat from his forehead from time to time.

What's the use of so many capable people and so many high-end scholars? We have to wait for Lei Chunming's operation to open this door.

Zhang Weiguo felt a sense of pride in his heart.

Lei Chunming fumbled carefully for two hours and finally straightened up.

"Most of them have been solved, but there are still a few things that are difficult to judge. We can only take a gamble. Professors, do you have any other opinions?"

Ji Yunyang and Li Cheng looked at each other, and Ji Yunyang asked: "According to your judgment, how far have we released the restrictions?"

"Three points two to four points three. Unless you get all the passwords, it is basically impossible to achieve 100%." ​​Lei Chunming grabbed the sweat towel in Zhang Weiguo's hand and rubbed his face hard.

Gu Chenzhou used his superpower again and submerged his consciousness into the stone door.

Most of the small metal pieces have been removed, but only three are still sealed on the door.

The large metal strip at the top has been moved, and less than a third of its length is stuck at the top of the door.

Ji Yunyang and Li Cheng discussed in a low voice, and signed their names together on the confirmation letter of the final key that Ding Yuanyi took out.

Lei Chunming stepped forward and operated based on the final confirmed password.

Gu Chenzhou felt another small metal piece move its position, but the mechanism behind the door was still not fully opened.

It's a pity that my metallic ability has just started, otherwise it shouldn't be difficult to just move the metal piece.

Everyone present once again put on protective clothing and masks.

Zhang Weiguo and Feng Yan stepped forward and pushed the door open. Guo Xiaoming, holding the remote control in his hand, stood on both sides of the door with everyone and retreated to a distance of about ten meters from the door.

The door was pushed open gently and deftly.

The middle hall was dark, and there was no scene of lights burning in the room last time when the door to the front hall was pushed open.

Zhang Weiguo and Feng Yanbian quickly retreated. Guo Xiaoming controlled the machine to drive towards the dark nave, and the headlights lit up at the base of the machine.

There was calm in the main hall, and the machine controlled by Guo Xiaoming slowly moved around the hall.

Under the light, everyone gradually saw the situation in the hall clearly.

The middle hall is only about half the area of ​​the front hall. Unlike the empty front hall, the middle hall is full of jewels and brilliance.

The hall is surrounded by magnificent murals.

A stone altar was placed in the center of the hall. In front of the altar, two rows of long stone tables were piled with a large number of gold, pearls and jade articles.

There are also some gold and silver scattered on the ground at the door.

It was like someone accidentally scattered the jewelry while moving it.

The machine moved in the hall, passing the gold and silver on the ground from time to time, and the machine also bumped along with it.

The chassis of the machine was very low. When it reached the depths of the nave, it was stuck by a large piece of gold and the machine stopped.

"Zi." A large amount of white gas suddenly spurted out from the top of the middle hall. The white gas quickly filled the middle hall and spread to the front hall.

Guo Xiaoming calmly fiddled with an instrument at hand and used the headset in the protective suit to convey the message to everyone: "It is a flammable and toxic gas. Everyone should evacuate first."

Ding Yuanyi and Sun Dajun led everyone out of the tomb.

Gu Chenzhou, Li Ye, Jiang Wutu and Guo Xiaoming stayed where they were.

Guo Xiaoming checked the values ​​of the instruments in his hand and took out four small machines from the equipment box.

It was delivered to the three people left behind: "Put it in the four corners of the front hall. We still have one minute."

Gu Chenzhou and Jiang Wutu held the machine and ran to the two corners of the front hall near the middle hall.

Li Ye and Guo Xiaoming ran towards the two corners closer to the door.

The machine is not large, about a quarter cubic.

No noise was made while working.

After starting, the air outlet of the machine spits out white cold air.

The temperature of the air conditioner was extremely low, and those holding the machine could not help but shiver.

The four people in the front hall heard the sound of "clank, clang, clang" at the same time.

The sound of arrows piercing the air suddenly sounded in the middle hall, and Gu Chenzhou, who was half-conscious, was startled.

Open your eyesight and look towards the nave.

Arrows were seen shooting out from all around the temple like locusts, intertwining densely in the white mist.

The cauldron on top of the stuck machine seemed to have opened a pair of invisible hands, attracting all the arrows flying in the air to one place.

The flying arrows flew towards the open mouth of the pot like moths to the flame, and the pot was filled with arrows in an instant.

The temperature in the front hall dropped rapidly. Gu Chenzhou did not dare to look further and exited the tomb with everyone.

At twelve o'clock at noon, Gu Chenzhou, Ding Yuanyi, Jiang Wutu, Li Ye, and Guo Xiaoming stayed outside the tomb, while the others returned to the camp first.

Inside the door of the tomb, a deep coldness came out.

The scorching sun was in the sky at noon, but the ancient tomb was as cold as an ice cellar.

Guo Xiaoming shivered, dragging a large box and standing farthest from the tomb.

Jiang Wutu looked at everyone, walked to Guo Xiaoming, and began to take off the protective clothing.

"Guo Xiaoming, how long will it take for this poisonous gas to dissipate?"

Li Ye came over holding the protective suit he had taken off.

He threw the protective clothing into the equipment box next to him.

"We are going to release carbon dioxide for half an hour. After an hour, we will extract the harmful gases and then we can enter the site again." Guo Xiaoming was obviously frozen, and it took him three times to say these two sentences in full.

"What would have happened if we had not released the carbon dioxide? When I came out, there was the sound of arrows piercing the air in the middle hall." Gu Chenzhou and Ding Yuanyi walked over together.

"The gas emitted from the nave is toxic and flammable, and its composition is somewhat close to that of methane."

Guo Xiaoming showed everyone the data displayed on the instrument in his hand.

"You see, open flames are used in the front hall and passages. The middle hall is completely dark. Those who enter must be carrying open flames."

Ding Yuanyi continued what Guo Xiaoming said and added: "The Wei Dynasty had no other lighting tools."

"We did not unlock all the mechanisms when we entered. According to the design of the mechanism in the middle hall, the mechanism in the middle hall only starts to emit gas after people enter the middle hall."

"At this time, the vision of people inside is blurred, and the gas sprayed out is flammable and explosive. As long as someone comes holding an open flame, the nave will burn on the spot. Even if the visitor does not enter the nave, he is still in the front hall, and the gas seeps out. When the concentration reaches a certain level, the open flames in the front hall and passages will still ignite the tomb chamber."

"Experienced tomb robbers always carry phosphorus lights when entering tombs, because they are afraid of encountering such a situation."
