Darkness enveloped the 150-meter-deep Yangtze River, and the hazy shadows implied faint light. They shuttled like fish in the dark water, stopping in front of a huge shadow.

The huge shadow cannot see the whole picture. Through the mask of the diving suit and the faint light of the diving lamp, Jiu De Mai can only see the rusty bronze wall that is several feet thick. It extends up, down, left and right, and it seems that there is no boundary. Unlimited.

Jiu De Mai keeps the "meditation", swimming along the wall, even wearing a heavy diving suit, she moves like an elegant mermaid, but the meditation envelops her, the darkness envelops the meditation, so this mermaid No one in the world can appreciate it, only the faint diving light shows through, like a ghostly spot.

Until a certain moment, the mermaid stopped slowly and faced the bronze wall. With the weak light of the diving lamp, she saw that a large area of ​​wall corrosion had been stripped off by some strange force, revealing the true color similar to gold—according to the tin The copper ratio is different, and the color of the unrusted bronze is between golden and gray.

The rusted and stripped bronze wall reveals an artistic decoration-a raised face, the mouth grows beyond the limit of human beings, and the throat is a hole with a diameter of about one meter. The upper and lower sides of the hole are sharp as daggers. teeth.

"I don't see that the King of Bronze and Fire is still an artist. The decoration style of this gate is very unique, but it looks a little smaller."

Jiude Mai pressed the earphone channel on the diving helmet.

Her equipment is even better than Kassel’s diving equipment. It can still maintain stable communication at a depth of 150 meters. This is not what the current technology can do, otherwise the Kassel Academy is unnecessary. Let the student hit two signal wires on the diving suit-now those two wires are still running at the entrance of the hole, extending all the way in.

"Don't be mean, go in and release that thing," 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 entered in advance, just in case. What mechanism did they touch during this process? Even if you use that potion, you may not be able to escape. Then you really have to stay and talk about art with the King of Bronze and Fire, provided that he didn't plan to use you to pinch it. The mold then casts a bronze beauty artwork."

"I see, you are like an old mother in a long-winded manner."

Jiude Mai swims in along the entrance of the cave, passing through the dark and deep passage, and his eyes suddenly open up. Numerous bronze gears of different sizes and shapes bite into each other, and the two qualities of magnificence and delicacy are displayed in front of Jiude Maii at the same time.

These gears are the transmission system of the palace. Casting a city entirely made of bronze is an unimaginable mighty force for Jiude Mai, but with these gears, here is not just a bronze city purely forged by mighty force, but an unrivaled city. The power and wisdom of the world cast the bronze organ city.

It's just...what is the source of power for such a huge city? Whether it is water or wind, it is impossible to drive the metal of an entire city, right? Bronze is not a light and handy thing like wood...

A huge bell-like roar sounded from the inside of the entire bronze city, and the dusty gears began to rotate, driving the surrounding water to move. Jiu De Mai looked at this scene dumbfounded, and turned to look at the secluded passage that she used to enter. When has disappeared.

"Potato chips," Jiu De Mai swims forward, yelling in her mouth, "I'll go back and choke your crow's mouth!"

...

On the side string of the Moniah, Lu Mingfei is standing on the side string in a diving suit. At this moment, his styling is as humorous as that of Professor Mans who wore a father and son diving suit ten minutes ago.

Three oxygen cylinders are tightly attached to his back side by side, one is attached to the wetsuit, and the other is not unsealed. There is a dark sheathed long sword pinned on the left waist, and the one on the right waist is wider than the left waist. At least double the epee, the two swords are surprisingly similar in style. They are made of Han hilt and modern scabbard, except that a three-foot-long bronze chain hangs from the hilt of the epee.

"Brother Lu, remember, the Dragon Slashing Platform can only use the scabbard and the sword chain, and the sword body cannot be pulled out, otherwise the living spirit inside will have to pay the price of life!"

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

"I have asked Norma to inform the school, so you don't have to take risks."

Professor Mans made the final persuasion.

As the commander of this operation, he had the power to let Lu Mingfei stay on the ship honestly and not allow him to take any risks. In fact, he did that. After all, the Bronze City had already been opened at this time. According to Ye Sheng In return, the passage inside is changing all the time, and going to the rescue by one person now is almost equivalent to going down and falling into danger with Ye Sheng and the others.

But Lu Mingfei just dialed the principal’s phone and calmly told the legendary silver-haired dragon slayer that he was going to the bottom of the Yangtze River to save people. The principal smiled and nodded in agreement. Professor Mans could even see from his eyes. To the kind of relief that the elders who see their younger generations become talents flow out.

Damn it! Principal, you think there are too many first-level researchers in the equipment department, are you ready to take this opportunity to get rid of one? !

What makes Professor Mans even more incomprehensible is that the principal actually stopped Norma from summoning the school’s A-grade students to try to crack the order of Bronze City. He only asked Norma to summon all honorary professors, tenured professors and full professors to form a temporary think tank. Although he also knows that relying on pedigree to break the Dragon King's Palace is really a small probability event, but it is better to gamble than to wait for death.

Or did the principal really pin his hopes on Lu Mingfei, a civilian researcher? This is anxious for this child to die!

"Professor Mans, what time is it now?"

Lu Mingfei ignored Professor Mans's persuasion and asked endlessly.

"Now... At 10:30 in the morning, the Maritime Safety Administration has just notified us that the weather will be worse this afternoon, and the strong wind may reach level 10. What's wrong?"

Professor Mans said.

"It's half past ten," Lu Mingfei nodded, "If it goes well, I should be able to catch lunch when I bring Brother Ye Sheng and the others."

"what?"

Professor Mans widened his eyes, thinking that the sound of the torrential rain was interfering with his hearing.

"I remember lunch seems to be dumplings, right? Professor remember to help me talk to the chef. If you have pork and green onions, please cook more."

After Lu Mingfei finished speaking, a fierce man plunged into the river water, and only a signal line and a lifeline made of nano materials were left in the turbulent waves.

Falling into the water, the darkness deeper than the shore instantly envelops Lu Mingfei, the bright golden pupils light up, and part of the true energy splits into mana pouring into the spiritual platform, as if the curtain of curtains in front of the eyes is opened, and everything becomes clear. Even the darkness couldn't stop Lu Mingfei's gaze.

Quickly pinched a water avoidance trick, Lu Mingfei headed towards the lower reaches of the water.

Over the past year or so, he has learned more advanced water avoidance tactics from the book of heaven, replacing the emergency goods that he learned at the beginning. The new water avoidance tactics not only allows him to breathe freely under water for a long time, but also water The resistance and pressure on him will also be greatly reduced.

In January 2000, Cuban Francisco Ferrira set a new record of 162 meters in the Gulf of Mexico, which took 3 minutes and 12 seconds. This result is already very good even for mixed races.

For Lu Mingfei, even if there is a diving suit in the way, it only takes about 30 seconds to dive to the Bronze City at a depth of 150 meters.

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

"Report to the captain! Lu Mingfei is diving, but at this speed...wait! Five meters per second?! Some ordinary people running on the ground are a little faster than this!"

Professor Mans wiped his wet hair with a towel, and heard the operator's exclamation striding over, staring at the screen showing the location of Lu Mingfei-where a small red dot representing Lu Mingfei was visible to the naked eye The speed moved downwards, and then slowly stopped. Judging from the picture from his head shot, he had already dived to the depth of the Bronze City. Next, he only needed to find the door-but after Jiu De Ya Ji touched the mechanism The door has been closed.

"What's the surprise? Isn't it normal for the water booster to have this speed?"

Professor Mans felt that the students were making a fuss and decided to deduct a sum from his internship points.

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

The reporter stammered, and Professor Mans's hand holding the towel to wipe his hair froze.

"Researcher Lu Mingfei's heart rate has dropped below the safe line!"

Selma stared at Lu Mingfei's ECG and exclaimed.

"What?! Get ready to help!"

Professor Mans dropped the towel and strode to Selma's monitor, which showed that forty seconds had passed since Lu Mingfei entered the water, but his heart rate was only six, an average of only nine times per minute.

"Professor, don't worry, I just have a strong heartbeat, so my heart rate is relatively slow. You know, athletes have a slower heart rate than ordinary people, and a mixed-race heart rate is slower than athletes." Lu Mingfei's flat voice came out from the communication channel. The command room echoed clearly, "If I didn't predict it wrong, professor, your heart rate should be between 20 and 30, right?"

Professor Mans nodded subconsciously. His heartbeat in a calm state is about 25 beats per minute. With a strong heart of mixed blood, a heartbeat of every two or three seconds is enough to pump the whole body's blood and supply oxygen in a calm state~www. readwn.com~ Normally, even the best physical athletes have a heart rate of over 40.

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

But even if the heart rate of a mixed race is no matter how low it is, it is usually not less than 20 beats per minute. A situation like Lu Mingfei's heart beating once in six or seven seconds can still be alive and kicking, Professor Mans is simply unheard of!

Does your heart beat once can pump the blood of your whole body to circulate in your blood vessels for two laps? ! This is already anti-biological! And you just finished an intense exercise of 150 meters down in 30 seconds, did your heart rate and breathing rhythm not change? !

Damn it! What level of blood are you on earth? !

Professor Mans had countless old slots stuck in his chest and couldn't spit out in his throat, but in the end they all turned into hope-Lu Mingfei's physical fitness is definitely strong to a terrifying point, and his blood unity is also extremely strong. , Maybe they can really save Ye Sheng!
