Chu Zihang first connected the wires in the broken rope on the ground and made a fire knot, but his movable distance was much shorter than before.

"Brother Chu, can you still go?"

Lu Chen pulled Chu Zihang up.

"It's OK, but it may not be possible to release the spirit for a while."

Chu Zihang has relieved the blood burst, but his golden pupil can't be extinguished, even more dazzling than before. He can feel that his body is gradually eroded by dragon blood. The side effects of three degrees of blood burst are great. It can be said that he is only one step away from falling into death.

The use of three degrees of violent blood also means that his death slide is more steep. Maybe I don't know that day when I see brother Lu again, the knife in each other's hand is aimed at his heart.

"Don't think too much."

Lu Chen patted Chu Zihang on the shoulder.

"Brother Lu, your hand?"

Chu Zihang pointed to Lu Chen's hands. At this time, the diving suit in his hands had already broken. After all, even if its quality was good, it could not be intact in the violent impact and friction of Lu Chen's bombardment of the bronze door. His hands exposed to the red water looked a little red, and the fist bones were still bleeding. The force was interactive.

Chu Zihang saw brother Lu bleeding for the first time, and what worried him more was the temperature here. Once the diving suit broke, the red water close to the boiling temperature would pour in.

"It's all right. I'm not too afraid of heat."

Lu Chen took out a spare short rope to fasten his wrist. He could endure the high temperature.

Chu Zihang was still worried and wanted to add some knowledge that deep-water wounds combined with sudden changes in air pressure might cause air embolism, but brother Lu didn't speak anymore.

Just keep it in mind.

Lu Chen observed the situation around him and said, "let's go out first. You're ready."

"Ready? Ready for what?"

Caesar asked a little tired. The continuous use of the blood sucking sickle had hollowed him out.

"Go out first."

Lu Chen checked the rope between his waist. After confirming that it was fixed, his body pressed down slightly.

"Brother Lu, you don't want to."

Chu Zihang guessed what the other party wanted.

"You're too slow. Now the water flow slows down. It's reasonable to hurry up and leave the bronze corridor."

Lu Chen said and leaned over slightly. Yuan Zhisheng finally understood what the other party wanted. They turned pale one after another, adjusted their posture and floated in the water.

Lu Chen used both hands and feet, and the huge water swept past him. He was like an incarnation of a sailfish sprinting underwater, and suddenly burst in and out.

If someone else is here, you will see a very funny scene. Lu Chen's posture in front of him is not beautiful, but he is very fast. On the left of the rope behind him is a dull looking yuan Zhisheng, and on the right are Caesar and Chu Zihang, which is like flying a kite.

The world's fastest fish can reach 109 km / h underwater, but Lu Chen's forward speed is almost twice that at this time, just like an underwater torpedo. If there are people hanging behind him who are also subject to underwater resistance, he can be faster.

After about three minutes, Lu Chen stopped.

Not because Chu Zihang said in the public frequency that he felt a little sick, but that he noticed something wrong.

He has traveled more than ten kilometers. It is difficult for underwater people to judge the verticality, but Lu Chen can still feel that the jinlunjia corridor should be inclined upward. How can it be so long?

"Lu Jun, you found it, too."

Yuan Zhisheng said, holding his body steady, he looked at the murals carved on the bronze walls on both sides.

"What do you mean?"

Although Lu Chen is very unhappy with Yuan Zhisheng at the moment, he knows that he has to rely on this "educated" student here.

"We're back."

Yuan Zhisheng doesn't look very well at this time.

Lu Chen looks at the murals on both sides. It seems that he is somewhat familiar, but he is not sure.

Yuan Zhisheng removed the pulley at his waist. He walked back a few steps and touched a wall. His face became worse. He waved and said, "come and see."

Lu Chen came up and saw a shallow knife mark on the bronze wall.

"How do you row?"

Lu Chen thought of something and his face gradually became strange.

Yuan Zhisheng nodded and said, "this is the mark I left on the wall with a spider when you first ran with us, Lu Jun. we're back again."

"Could it be a knife mark that existed before?"

Caesar had just regained some strength and frowned at the knife marks on the wall.

"No, of course I remember."

Then yuan Zhisheng pulled out the spider and cut it and compared it on the wall.

Chu Zihang came up and touched the knife mark. "It's a new mark, no rust."

He was a little blue at this time, mainly because he was not very good at this fierce project, so he never played roller coaster in the amusement park.

"Have you seen this before?"

Lu Chen asked. He had seen glass in the wind and knew that Yuan Zhisheng had many things to hide from them. He thought of his main task. The secret hidden by the other party was likely related to Bai Wang.

As an important figure in the Japanese branch, Na Yuan Zhisheng should know a lot about these things in China.

He thought about the glass in the wind. He still didn't report to the college for the time being. He always had a hunch that this person might be of some use.

"No... but we are all students of Kassel college. You should have learned something about this strange phenomenon in the course."

Yuan Zhisheng looked at the oxygen count. They had only 30 minutes left, but they were trapped here.

"Nibelungen."

Chu Zihang's voice was a little dry. After the blood burst, the weak golden pupils became dazzling again. It seemed that there was a flame burning from the abyss to rush into the world. It was the flame of revenge.

Lu Chen silently looked at Chu Zihang and knew that this was not the time to talk about other things. He only asked his main doubt, "Nibelungen?"

"Brother Lu, you don't know. It's not surprising that this is something that only sophomores will talk about. Nibelungen is the country of the dead in Nordic mythology... The country of fog, nefalheim, which is a place that can't be reached by the living. Only the dead can go. All substances in Nibelungen are dead, including elements."

Kathleton looked down at the endless golden gallon corridor and said, "Nibelungen is usually built by pure blood Dragons of more than one generation. We may really meet a big guy this time."

Lu Chen wondered, "but what does this have to do with the situation we are facing now? Whether the element is dead or alive doesn't seem to be the problem we should care about now. Our current situation is like ghosts beating the wall."

Lu Chen knows very little about Nordic mythology. He has heard of ghosts hitting the wall, but this is also the first time to see him.

"The rules in Nibelungen are made by the owner here. According to Yuanjun, this is the golden gallon cloister, which means the meaning of the abyss, and the abyss is infinite. This should be the rule set by the dragon who created Nibelungen."

Chu Zihang explained that this strange environment was not the first time he had met. Although he could not say it clearly, he should be the most experienced in understanding Nibelungen.

He also drove Maybach on the elevated road. Later, he calmed down and thought that the distance he drove was too far compared with the exit of the elevated road.

He even suspected that if his father hadn't struggled to drag the guy in the shroud, he wouldn't have run to the exit at all.

"The dragon clan is really boring. Since we are now in Nibelungen, which is what brother Chu said, this is its world, it should have noticed our arrival, but now this attitude is closing the door and refusing guests?"

Lu Chen is a little depressed. He always listens to the college talk about how cruel and proud the dragon clan is, but what he meets is not very refreshing goods. Why don't he come out straight and get cut?

"It is said in the course of the college that the rules in Nibelungen are preset by the dragon family. It is their private space and also plays a certain role in resisting the enemy. This can be regarded as a self-protection mechanism. If the owner here is still sleeping, he may not know we are coming."

He began to look at the childish murals on the wall and try his best to explain them.

"What should we do now?"

Lu Chen is calm, but he is not very optimistic. He can barely open a piece of bronze horizontally and slowly. However, it is no doubt a fool's dream to beat down and remove the bronze block above, and then find a way to dig through the rock stratum.

Moreover, after listening to the explanations of Chu Zihang, he knew that this place was a little evil. Most of it could not be cracked by brute force. Behind these huge bronze blocks, there may not be rock strata.

At this time, he was a little lucky. Fortunately, he didn't come down alone. There were several "intellectuals" such as brother Chu. Otherwise, he was really blind at the moment.

"Nibelungen, from the point of view, there is a 'birth gate', but we have to understand the rules here before we have a chance to find the birth gate."

Chu Zihang analyzed, and he also looked at the murals on the wall. From the ground to the wall to the top of this jinlunjia cloister, there are murals, as if recording some kind of epic.

His hand stretched out and felt the space. Sure enough, the water was not flowing, and everything here was dead.

Entering Nibelungen requires some kind of interface, such as water, mirror and other media, and they are in the underground river. There are media everywhere. Brother Lu just rushed too fast, and he was a little dizzy, so it is impossible to speculate when they entered Nibelungen

Now the only clue is these murals on the wall.

He turned to Yuan Zhisheng and said, "Yuan Jun, this place is written in your God's language. Can you understand it?"

Even if he is erudite, this language is too unpopular. Now he can only rely on the source and young students.

Yuan Zhisheng looked solemnly at the murals in front of and behind the cloister. His face was not very good: "the wall that I can understand and leave a mark seems to be the beginning of the record."

Because Lu Chen's advance speed was too fast before, he only had time to draw the knife marks and didn't take a close look at these murals, but this mural seems to be the beginning of all the stories. Is this a coincidence?

For some reason, Yuan Zhisheng suddenly felt that a shadow called fate had found them, hid behind them and burst into harsh laughter.

At this time, Lu Chen also retreated slightly and looked at the mural.

At the top of the painting is a vague shadow, which seems to mean chaos. Below is a deeply cracked and incomparably huge gap. The whole gap is empty and nothingness, no trees, no weeds, nothing and nothing.

After watching carefully, Lu Chen was also restrained by the mural. He didn't know anything about carving and painting, but he could also realize what kind of master the mural Carver was. Every stroke showed a magnificent momentum. The vastness of the ancient times came out through the mural and went straight into people's mind.

"The golden lunga gap represents the absolute emptiness before the creation of the world in Nordic mythology."

Chu Zihang couldn't understand the words above, but he saw what the painting was.

"What does it say?"

Caesar has a wonderful way. He looks at Yuan Zhisheng. He is as familiar with Nordic mythology as Chu Zihang. The words they can't understand are the key.

After reading it word by word, Yuan Zhisheng translated: "this is a sinner's account of history. It says that the golden lunga gap is the original place and the beginning of everything."

"The guilty?"

Lu Chen wondered why the guy who created these murals claimed so much.

"Lu Jun, don't interrupt me first. There are a lot of murals. We don't have much time. We'll look at them while we walk. I'll translate them in real time. If there are key clues, we'll discuss them again."

Yuan Zhisheng said and began to interpret these murals again.

Lu Chen shrugged. Illiteracy has no human rights, but he didn't talk to the source students about it. Besides, he also knows that time is tight now. It seems that after returning to the college after this task, he should also study more culture classes.

The next mural in series shows the intersection of ice and fire, the birth of an indomitable giant, which is so conspicuous even in the grand golden lunga gap.

Yuan Zhisheng's voice said: "when the heat wave in the hometown of fire meets the rime, it melts into water droplets. With the power of heat source, the water droplets have the pulse of life, and then they show their human shape. They are called youmier (not that youmier!)."

Chu Zihang and Caesar did not interrupt, but when they looked at each other, they saw the shock in each other's eyes.

Although the college often takes Nordic mythology as a reference for the history of the dragon family, many of them think it is nonsense, but now on the wall of the history recorded by the dragon family, they actually see the golden lunga gap and the original giant Emir!

That's the first life in the beginning. Even the world tree is just a tree growing from his heart in Nordic mythology!

This is a great discovery of the century, which is even more shocking than the discovery of the lost country Atlantis at the bottom of the sea. If these news can be sent back to the college, it will be a major step on the road of understanding the dragon race, which is comparable to human stepping on the moon!

Yuan Zhisheng took several people step by step through the jinlunjia cloister. His voice was calm but spoke very fast because they didn't have much time.

Lu Chen was immersed in some of the great stories of the ancient times, even though they came from the ancient times.
