When I was supposed to be slaying the dragon, I accidentally started cultivating immortality

Darkness enveloped the Yangtze River, which was 150 meters deep. The hazy shadows contained a shimmer of light, and they shuttled like fish in the dark river water, stopping in front of a huge shadow.

The huge shadow could not see the whole picture. Through the mask of the diving suit and the weak light of the diving light, Mai Shutoku could only see the rusted bronze wall several feet thick. It extended up, down, left and right, seemingly without boundaries. Unlimited.

Mai Shutoku maintained her "Mei Zhao" and swam along the wall. Even though she was wearing a heavy diving suit, her movements were like an elegant mermaid. However, Mei Zhao enveloped her and darkness enveloped her, so this mermaid There was no one in the world to admire, only the dim light of the dive showed through, like a ghostly spot of light.

Until a certain moment, the mermaid slowly stopped and faced the bronze wall. With the faint light of the diving light, she saw that a large area of ​​rust on the wall in front of her had been peeled off by some strange force, revealing a true color that was close to gold. According to the tin Depending on the proportion of copper, the color of untarnished bronze ranges between golden and off-white.

The rusted-off bronze wall revealed an artistic decoration - a convex human face with a mouth that grew beyond human limits. There was a hole about one meter in diameter at the throat. Above and below the hole were two rows of sharp daggers. teeth.

"I can't tell that the King of Bronze and Fire is still an artist. The decoration style of this door is very unique, but it looks a bit small."

Mai Shutoku pressed the headset on her diving helmet.

Her equipment is even better than Kassel's diving equipment. She can still maintain stable communication one hundred and fifty meters underwater. This is not something that the current technology can achieve, otherwise Kassel Academy would not have the need. Attach two signal wires to the student's wetsuit - the two wires are still hanging at the entrance of the hole and extending all the way in.

"Stop talking nonsense, go in and let that thing out," Su Enxi urged, "This is not only the Dragon King's palace, but also their sleeping place. Your sister and her little boyfriend have already gone in in advance, just in case. They triggered some mechanism during this process. Even if you use the potion, you may not be able to escape. At that time, you will really have to stay and talk about art with the King of Bronze and Fire. The premise is that he does not plan to use you to pinch him. The mold was then cast into a bronze statue of the beauty.”

"I know, you're so verbose as an old woman."

Mai Shuitoku swam in along the entrance of the cave, passed through the dark and deep passage, and suddenly her eyes opened up. Countless bronze gears of different sizes and shapes meshed with each other. The two qualities of magnificence and delicacy were displayed in front of Mai Mai Mai's eyes at the same time.

These gears are the transmission system of the palace. Casting a city entirely made of bronze is already an unimaginable power of Mai Shutoku. But with these gears, this is not just a bronze city simply made of power, but a city made of unparalleled power. The strength and wisdom created the bronze organ city.

It’s just...such a huge city, what is its power source? Neither water nor wind is likely to move an entire city of metal, right? Bronze is not something light and flexible like wood...

A huge bell-like roar sounded from inside the entire bronze city, and the dust-covered gears began to rotate, causing the surrounding water to flow. Mai Shutoku stared at this scene in stunned silence, and turned around to see that the deep passage for her to enter was unknown. When has it disappeared.

"Potato chips," Mai Shutoku swam forward and cursed, "I'll go back and strangle you to death!"

…

The Monyach was on the side string, and Lu Mingfei was standing on the side string wearing a diving suit. At this moment, his appearance was no less humorous than Professor Mann's, who was wearing a father-son diving suit more than ten minutes ago.

Three oxygen bottles were placed tightly side by side behind his back. One was attached to a diving suit, and the other two had not yet been unsealed. On his left waist was a dark sheathed long sword, and on his right waist was a sword that was wider than the left waist. At least twice as long as the heavy sword. The two swords are surprisingly similar in style. Both have Han-made hilts and modern scabbards. However, there is a three-foot-long bronze chain hanging from the hilt of the heavy sword.

"Brother Lu, remember, you can only use the scabbard and sword chain on the Dragon Slaying Platform. The sword cannot be pulled out, otherwise you will have to pay the price of your life to the living beings inside!"

Zhou Minhao and Professor Mance stood in the rain together and warned Lu Mingfei seriously.

"I've asked Norma to notify the school, so you don't have to take the risk."

Professor Manns made his final persuasion.

As the commander of this operation, he had the full power to ask Lu Mingfei to stay on the ship and not to venture out - in fact, he did so. After all, the Bronze City was already open at this time. According to Ye Sheng's In return, the passage inside is changing every moment. Now, going down alone to rescue is almost equivalent to going down alone to be in danger with Ye Sheng and the others.

But Lu Mingfei just dialed the principal's phone number and calmly told the silver-haired legendary dragon slayer that he was going to go to the bottom of the Yangtze River to save people. The principal smiled and nodded in agreement. Professor Mance could even see it in his eyes. The joy that comes from the elders who see their younger generation become successful.

Damn it! Principal, do you think there are too many first-level researchers in the Equipment Department and are you going to take this opportunity to get rid of one? !

What makes Professor Mance even more incomprehensible is that the principal actually stopped Norma's order to summon all A-level students in the school to try to crack the Bronze City. He only asked Norma to gather all honorary professors, tenured professors and full professors to form a temporary think tank. Although he also knew that relying on bloodline inspiration to crack the mechanism of the Dragon King's palace was a small probability event, but taking a gamble was better than waiting to die.

Or does the principal really place his hopes on Lu Mingfei, a civilian researcher? I wish this child would die!

"Professor Mance, what time is it now?"

Lu Mingfei ignored Professor Mance's persuasion and asked a confused question.

"Now...at 10:30 in the morning, the Maritime Safety Administration just informed us that the weather will be worse in the afternoon, and the strong winds may reach level 10. What's wrong?"

Professor Manns said.

"It's half past ten," Lu Mingfei nodded, "If everything goes well, I should be able to make it in time for lunch when I bring Senior Brother Ye Sheng and the others up."

"ha?"

Professor Mance's eyes widened, thinking that the sound of the pouring rain had interfered with his hearing.

"I remember that lunch seemed to be dumplings, right? Professor, remember to tell the chef for me. If there is pork and green onions, please cook more."

After Lu Mingfei finished speaking, he plunged down into the river. Only a signal line and a nano-material lifeline were left in the turbulent waves.

After falling into the water, Lu Mingfei was instantly enveloped in a deeper darkness than on the shore. His dazzling golden eyes lit up, and part of his true energy was divided into mana and poured into the spiritual platform. It was as if a gauze curtain had been opened in front of his eyes, and everything became clear. Even the darkness couldn't stop Lu Mingfei's gaze.

Lu Mingfei casually made a trick to avoid water, and swam towards the water.

Over the past year or so, he has learned more advanced water-avoiding techniques from the Book of Heaven, replacing the emergency equipment he first learned. The new water-avoiding techniques not only allow him to breathe freely underwater for a long time, but also allow him to breathe freely underwater. The resistance and pressure on him will also be greatly reduced.

In January 2000, Cuban Francisco Ferreira set a new record of 162 meters in the Gulf of Mexico, taking 3 minutes and 12 seconds. This result is already excellent even for mixed races.

For Lu Mingfei, even if a diving suit was in the way, it would only take about thirty seconds to dive to the Bronze City at a depth of 150 meters.

So in the command room on the ship, the Baizhan elites in the execution department stared at the monitor in front of them and exclaimed in astonishment.

"Report Captain! Lu Mingfei is diving, but at this speed... wait! Five meters per second?! Some ordinary people can only run a little faster than this on the ground!"

Professor Mance was wiping his wet hair with a towel. When he heard the operator's exclamation, he strode over and stared at the screen showing Lu Mingfei's position - there was a small red dot representing Lu Mingfei visible to the naked eye. The speed moved downward, and then slowly stopped. Judging from the picture transmitted by his head camera, he had dived to the depth of the Bronze City. The next step was to find the door - but after Shuode Aki triggered the mechanism The door has been closed.

"Why are you surprised? Isn't it normal for a water pressure booster to have such a speed?"

Professor Manns felt that the student was making a fuss and decided to deduct a point from his internship.

"But...but because Researcher Lu Mingfei's diving suit has to carry three tanks of oxygen and two weapons at the same time, and it also needs to leave a certain underwater movement space for him to find Commissioner Ye Sheng and the others in the Bronze City, it has been... The hydraulic booster has been removed, I did it myself a few minutes ago."

The reporter stammered, and Professor Mance's hand froze as he wiped his hair with a towel.

"Researcher Lu Mingfei's heart rate has dropped below the safety level!"

Selma stared at Lu Mingfei's electrocardiogram and exclaimed.

"What?! Prepare for rescue!"

Professor Mance threw down his towel and strode to Selma's monitor. It showed that forty seconds had passed since Lu Mingfei entered the water, but his heartbeat was only six times, which was an average of only nine beats per minute.

"Professor, don't worry, I just have a strong heartbeat, so my heart rate is relatively slow. You know, the heart rate of athletes is slower than that of ordinary people, and the heart rate of mixed-race people is slower than that of athletes," Lu Mingfei's plain voice came out from the communication channel. The command room echoed clearly, "If I'm not wrong, professor, your heart rate should be between twenty and thirty, right?"

Professor Mance nodded subconsciously. His heartbeat in a calm state is about twenty-five times per minute. With a strong mixed-race heart, a heartbeat of every two to three seconds is enough to pump blood and oxygen throughout the body in a calm state. Usually, normal Even the most physically fit athletes have a heart rate above 40.

Of course, all this is based on the natural heart rate achieved by strong physical fitness and cardiopulmonary function. If the heart rate is too low for ordinary people, they are sick and must be sent to the hospital quickly.

But no matter how low the heart rate of a mixed race is, it is usually not less than twenty beats per minute. It is simply unheard of for Professor Mance to have a heart like Lu Mingfei's heart beat every six or seven seconds and still be alive and kicking!

Can your heart pump the blood throughout your body and circulate it twice in your blood vessels once? ! This is already anti-biology! And you just completed an intense exercise of diving 150 meters in 30 seconds, and your heart rate and breathing rhythm didn't change at all? !

Damn it! What level of blood are you? !

Professor Mance had countless old things stuck in his throat that he couldn't spit out, but in the end they all turned into hope - Lu Mingfei's physical fitness has definitely reached an extremely terrifying level, so his bloodline must also be extremely powerful. , maybe we can really rescue Ye Sheng and the others!
