Nuonuo originally planned to forcefully pull Lu Mingfei's hand out. She knew that the result of continued air leakage might be death, and a broken wrist bone or something could be treated with water.

But after listening to Gu Chen's words, he immediately locked Lu Mingfei's wrist and waited nervously. Every second felt long.

"He suddenly stopped biting me." Lu Mingfei took his hand out blankly.

Nono inspected the torn diving suit gloves with confusion. His injured finger was exposed from the crack. There was only a bloody opening less than one centimeter, and the depth was probably equivalent to a cut with a pencil sharpener.

The sharp teeth that looked like living wolf fangs were very suspicious of bluffing, and they stopped after cutting the kid's skin.

"Then what are you yelling about?!" Nuonuo suddenly became angry and hit Lu Mingfei in the chest with his elbow.

"Of course I was nervous to be bitten by a dead head. I thought it was going to eat me!" Lu Mingfei defended loudly. After locking his wrists, the pressure in the diving suit was restored, and he immediately became energetic.

"Okay, the door should be opened." Gu Chen's calm voice interrupted the bickering between the two, "You two hold on together and keep balance."

Upon hearing the second half of his sentence, Lu Mingfei's heart blossomed, thinking that at the critical moment, it would be you, Lao Gu, who would use your power to seek personal gain for your brother...

"Why are you so stunned?" Nono glared at him angrily and grabbed his wrist tightly.

Lu Mingfei was still giggling, and then he saw a big black mouth that seemed to be swallowing them up. It was a living creature. If he hadn't seen it with his own eyes, no one would have believed that someone could open his mouth so wide.

The structure of the mouth is like a giant snake that can swallow elephants.

"I'm going!" His vision went dark and he was sucked into the whirlpool.

When he opened his eyes again, he was not in water, but surrounded by air. Nono got up from the ground and looked around.

There is a bronze corridor in front of him. There are countless bronze statues standing on both sides of the corridor. They are all people wearing ancient clothes, civil servants or military generals, holding tooth wats in their hands. The only difference is that they protrude from the collars of their robes and armors.

They have long and slender snake necks, and the heads of these officials are all like cobras. What’s funny is that some of them even wear hats.

There was a humming sound coming from the side, and Lu Mingfei was cocooning on the ground.

Nono kicked him over with one kick.

"Report the situation." A familiar voice came from the earphones.

"Chen Motong reported that there was an accident, but we have entered the Bronze City and no one was injured. Lu Mingfei's diving suit is torn, but there is still oxygen left." Nuonuo said as he closed the door.

The two men opened the valves of their oxygen bottles, and then tried to unscrew the valves of their helmet masks, and a breath of coppery smell rushed in.

"The oxygen here is breathable. The only problem is that the communication line is embedded in the wall." She looked back at the black rope that served as both a communication line and a lifeline.

It did not break, but was magically inserted into the bronze wall behind it, seamlessly connected to the wall, as if it had been poured into it.

On the Monyach, Gu Chen said: "That wall is made of recycled metal. It has very good ductility and is as plastic as plasticine. Your communication lines will be stuck in it until the door is opened again."

His calm tone once again calmed down Nono and Lu Mingfei who were facing the unknown.

Next to him, Manstein glanced at him subconsciously. It was hard to believe that this was the magnanimity of a young man who had experienced such a thing for the first time. This was not only a dragon-slaying operation, but the target was one of the legendary four monarchs.

But there was no trace of nervousness on his face.

Maybe, this is the reason why he was selected by the school board. Manstein thought so, and then said: "This time we have experience, and you all carry extension cords in your pockets."

The two people in Bronze City found the spool of the extension cord from their pockets. They disconnected the black cord from the diving suit and connected the adapter cord in the middle.

"Call Monyach, can you hear me?" Nono said.

"The signal is very clear, no problem." Manstein replied immediately.

"There are two things that are not in line with expectations." Nono said: "First, the last time Ye Sheng and Yaji entered, the air here was no longer suitable for breathing due to the perennial oxidation of metals and depletion of oxygen. But now the air

The quality can already breathe normally. Secondly, before I had time to use the blood of the 'key', the door really opened like the old man... Teacher Gu said, was it because of Lu Mingfei's blood?"

Manstein said: "The air can be breathable now because the Dragon King has returned to his palace. He is a reptile and breathes oxygen. In other words, he is near you now."

Lu Mingfei suddenly looked around cautiously, "Professor, you said he won't wake up, right?"

Manstein gave him an affirmative answer, "Yes, to give birth to a giant body is equivalent to hatching it again. It should be in the state of an 'egg' now."

"I can answer the second question." Lu Mingfei raised his hand, "Lao Gu was right before he opened the door because he sucked my blood. I felt like I was taking a blood sample in the hospital.

."

Gu Chen smiled and said, "Can you describe it? I really can't imagine it."

"...You are making things difficult for me." Lu Mingfei said angrily.

Manstein was silent for a while and said: "The word spirit of the 'key' can open all the doors in the world, but to open the ancient bronze city, you use your own blood, not the power of the word spirit, but the advantage of your bloodline. So you

The dragon bloodline is also high-purity dragon blood."

"Am I really different?" Lu Mingfei said happily.

"Well, when we get back, we will carry it to the laboratory and use it as a blood bank." Gu Chen snorted, "hurry up and move forward!"

"Yes, yes, yes." Lu Mingfei curled his lips. This is a hateful class. Once they get a little bit of power, they look down upon their old friends.

"Are you scolding me?" Gu Chen said coldly.

"No way!" Lu Mingfei was shocked.

Gu Chen sneered, "It's not enough to slander me."

"Professor Manstein, you don't care, you are the captain!" Lu Mingfei shouted.

"Teacher Gu is right, you should save time." Manstein said in a deep voice: "Place the bomb as close to the Dragon King's palace as possible. The power of the bomb explosion is average, but the alchemy potion inside will react with water and metals.

A strong chain reaction will quickly exhaust the air in the Bronze City. The hatching Dragon King will feel suffocated and will have to break out of the egg in advance. By then he will be very weak and the storm torpedo can easily kill him."

Lu Mingfei stopped talking nonsense and just joked to relieve the tension.

"Understood, but we have to find a way first." Nono frowned and said, "In front of us is a corridor with many snake-faced statues on both sides."

"The Road to the Holy Temple, there is a record of this road in "The Ice Sea Fragments"." Manstein said: "In the era when the Dragon Clan was prosperous, the ancients had to go through this Holy Temple to meet the Dragon King as subjects.

Road. There is an identical road in the bronze palaces of Northern Europe. The snake-faced sculptures on both sides represent the metal elements controlled by the Dragon King. According to the alchemical element table, there are 88 types in total."
