Urban Immortal Cultivation, I can no longer hide my identity as an immortal doctor

The bronze gate, made of bronze, is two meters wide and five meters high, standing deep underground.

The bronze gate is connected to rocks on all sides, so it is unrealistic to dig a hole to bypass the gate.

Moreover, most ancient tombs are more sophisticated to consider the existence of tomb robbers, so it is almost impossible to bypass the gate by other means.

The only hope is to open the bronze gate from the front.

The bronze gate has traces of years and some rust, which looks quite old.

The surface of the gate is not smooth, but uneven, presenting a blurred picture.

However, no one can tell what this picture is.

The bronze gate is divided in the middle, with two animal ring handles. It seems that as long as you push it gently, you can push the bronze gate open.

But this method has been tried by Teacher Xia Wen a long time ago, but this bronze gate is like welded and cannot be pushed at all.

Last time, they tried many methods, but they were powerless.

Of course, with modern technology, it is not impossible to break this bronze gate, such as using explosives to blast it directly.

But that would lose the meaning of archaeology, so Teacher Xia Wen directly rejected this proposal.

During this period, they collected information and made a lot of deductions, and finally came up with three methods.

And today, they plan to try it.

However, this is just the idea of Teacher Xia Wen and others. In Su Yun's omniscient eyes, this bronze gate presents another form.

"Bronze! Pale green!"

Under the eyes of Tong Tian Ling, the entire bronze gate was glowing with a bright light.

This light was not only dim, but also very strange, like a twisted face, full of madness and hideousness.

At this time, Su Yun finally knew why the spirit possessed in Bai Shanshan's body was a pale green shadow.

It turned out that the reason for all this was this bronze gate.

This bronze gate was completely condensed by that strange pale green shadow.

At this time, in Su Yun's eyes, this bronze gate was like the gate of hell in the underworld. After it was opened, endless evil spirits would be released, and behind the gate was a terrifying world!

What was inside, even Su Yun didn't know

"Zhuo Wen, take out the things!"

At this time, other people did not know the horror of this bronze door, and Teacher Xia Wen was still instructing Zhuo Wen.

Zhuo Wen was holding a tool box in his hand. At this time, he respectfully opened the box and handed it to Teacher Xia Wen.

Su Yun looked up and saw a bunch of ancient keys in the tool box. There were keys of various shapes, and they were all keys for the door lock of this kind of door.

It seems that Teacher Xia Wen's first method is to try to open the door with the key.

"This bronze door has a long history and is suspected to be from the pre-Qin period. I have read many ancient books from the pre-Qin period, borrowed a few pre-Qin door keys from an old friend, and asked craftsmen to make a few keys based on the ancient books. Maybe I can open it."

Teacher Xia Wen put on gloves and carefully tried to open the door while explaining to the students.

This kind of opportunity to teach by example is rare, and everyone listened very seriously.

Even Bai Shanshan beside Su Yun and Zhuo Wen, who had always hated Su Yun, stared at Teacher Xia Wen's actions.

"There is something strange about this bronze door. I suggest you don't try to open it!"

After thinking for a while, Su Yun still spoke up to remind them.

Even he felt a little eerie about this bronze door, not to mention that Bai Shanshan and the others were just ordinary people, and they might not be able to bear it. As soon as Su Yun spoke, he immediately attracted everyone's attention.

"Boy, if you don't understand, don't pretend to understand, and don't try to gain a sense of existence by exaggerating. Teacher Xia Wen has excavated more ancient tombs than you have ever heard of. What qualifications do you have to teach us?"

Zhuo Wen seized the opportunity and sneered.

The other students also frowned slightly, and their impression of Su Yun became worse.

As for Teacher Xia Wen, he was too lazy to even answer, and tried to open the door on his own.

It's ridiculous that an outsider dares to talk nonsense here!

Seeing that everyone ignored his reminder, Su Yun said no more.

Your life is your own. Since they don't believe it, you can only wish for good luck!

However, Su Yun still protected Bai Shanshan behind him. The others had nothing to do with him, but Bai Shanshan was related to the Xie family after all, and he couldn't just watch her die.

In the dim ancient tomb, only the light of the flashlight was shining.

Teacher Xia Wen tried one key after another, but none of them succeeded. The first method failed.

"It seems that we can only try the second method!"

Teacher Xia Wen did not look discouraged. He called the second student and opened the second tool box.

This time it was an alloy hammer.

"Generally speaking, the four corners and cracks of the door are the weakest and most likely to be breached."

"This heavy hammer is an invention of the Academy of Science and Technology. It is made of rare metals and uses the principle of"four ounces to move a thousand pounds". It can exert great power with very little force!"

Teacher Xia Wen introduced while holding the alloy heavy hammer. After some exploration, he smashed it hard on the upper left corner of the bronze door.

When the hammer fell, Su Yun's all-seeing eyes saw that the bronze door trembled suddenly, and the cold and chilly aura became stronger. It was as if the sleeping evil spirit was about to be awakened and cause trouble in the world.

Su Yun's spiritual energy was running in his body, ready to take action at any time.

Boom!

Teacher Xia Wen hammered it down again, and the stimulated bronze door woke up more and more.

But in the end, the bronze door still did not wake up completely, and Teacher Xia Wen's second method also failed completely.

""Huh! It seems that the last method is the only one left!"

Teacher Xia Wen sighed slightly, his eyes becoming serious.

He had the best confidence in the first two methods, but they both failed.

He was not very confident about the third method, but now he had to give it a try.

"Last time I went back, I found a few friends to study together, and finally we came to a conclusion that the concave and convex marks on this bronze door are similar to a puzzle!"

Teacher Xia Wen explained while reaching out to grab a concave and convex stone and then turned it hard.

In the admiring eyes of everyone, the concave and convex stone can actually slide.

Teacher Xia Wen turned the stone step by step according to the result he deduced. Gradually, the pattern on the bronze door became clearer and clearer.

Click!

Finally, when the last stone slid, a slight sound was heard.

The next moment, this bronze door, which had been closed for who knows how many years, slowly opened in the surprised eyes of everyone!
