Before entering the water, Nuo Nuo looked at Lu Mingfei and said, "Remember, no matter what happens, listen to my command, I am the team leader, you are a team member, understand?" ”

"Remembered." Lu Mingfei had a stiff face.

Professor Manstein was still talking about Lu Mingfei's ears and heard the cocoon's "Safety Precautions for Underwater Operations", in fact, Lu Mingfei was already able to memorize it well, and it was a matter of life, so you must not worry about it.

"So, are there any questions now?" Manstein closed the manual and finally asked.

"I have!" Lu Mingfei raised his hand and asked, "Let's go to the Dragon King's house to plant a bomb, if he finds out, he will probably not be happy, what should we do then?" ”

"Don't worry, the 'Bronze Project' was formulated after a lot of research by the principal and all the professors, and according to our research results, the Dragon King should not wake up at this time, because he still needs a period of time to cultivate the dragon body." Professor Manstein said.

"Cultivating a dragon body?" Lu Mingfei was a little stunned.

"The body of dragons has many powerful changes, as long as there is a need, they can imitate almost any animal, and imitating into humans is just to facilitate integration into society, but this imitation also has a price, if you want to exert full strength, you must use the original form of the dragon body, it is impossible to do it with a human body. The dragon you saw at the academy was forced to break its eggs due to an accident in hatching, so its power went viral. And if this dragon king wants to exert the ultimate situation of the fire system, he must re-establish eggs and re-conceive a huge dragon body, so he will not wake up easily, so we use bombs to force him to hatch in advance. Professor Manstein explains.

"The final form of the fire spirit? What is that? Lu Mingfei asked.

"Candle Dragon, serial number 114, extremely dangerous, effect unknown. The Dragon King must want to regain his grasp of it, because he wants to bring the whole world to the funeral. Professor Manstein said, standing up, "It is for this reason that we must eliminate him." ”

"I'm fine." Lu Mingfei nodded, signaling that he was also ready.

"Good luck then." Professor Manstein waved his hand, and the two rolled over into the water.

Even with underwater spotlights, the visibility in the river would not exceed five meters, and the pressure under the water could be clearly felt, and the pressure gauge showed that they had reached a depth of 50 meters.

"There's going to be a crack underneath the predetermined location, and we're going to get inside." Nono said, "Follow me." ”

Slowly passing through the crack, the pressure gauge showed that the depth had reached eighty meters, and Nono looked up, and the spotlight shone ahead.

"Here we are."

In front of it is a huge bronze wall, boundless up and down, left and right, like a miracle.

Lu Mingfei swam in front of the giant wall and exclaimed, "Is this the White Emperor City?" The bronze ancient city, the real thing is much more shocking than the three-dimensional picture. ”

"There's a face here! It's so lifelike. Lu Mingfei pointed to the huge human face protruding from the bronze wall, which was a painful face, with a burning firewood in its mouth, and its shape was twisted and hideous.

"That's a living soul, it's taught in alchemy biology class." Professor Manstein's voice came out of the earphones, "The burning wood in the mouth symbolizes being imprisoned by the power of the flames, and the pain is never relieved." This is the handiwork of the dragon king Norton, he is the insurmountable peak of alchemy, and the strongest alchemy among the four monarchs, he manipulates metal and fire elements, can 'kill' metal with the purest flame, and then resurrect it, this metal that has been removed from all impurities is called 'regenerative metal', is the best material for alchemy, and can also imprison the soul. This is a imprisoned soul guarding the gates of the Bronze City at the behest of the Lord of Bronze and Fire. ”

"Is this thing still alive?" Lu Mingfei asked.

"Dead, 'living spirit' is the definition of alchemy, and his consciousness has long since died." Nono said.

Lu Mingfei suddenly lacked interest, this technique sounded quite bluffing, but it was obviously his sword spirit technique that was superior.

"Nono, there is a milliliter of 'key' blood in the vacuum tube you carry, smear the blood on the lips of the 'living spirit', and the high-purity dragon bloodline will open the entrance for you." Professor Manstein instructed.

Nono smeared the blood from the vacuum tube on the living spirit's lips, and the expression on the living spirit's face soothed a little, and soon its mouth opened wide, getting bigger and bigger, almost like a black hole, and the water began to flow violently, forming a whirlpool.

Nuno grabbed Lu Mingfei's wrist, and the two moved with the whirlpool and were swept into the hole.

When he opened his eyes, he saw that the inside of the Bronze City was actually air, and Nuno got up and looked around.

They are in a bronze corridor, on both sides of the corridor, there are bronze statues, are some strange snake-headed people, they are dressed in ancient clothes, or civil servants or military generals, holding the tooth wat in their hands, bowing slightly as if saluting, and the head of the rice shovel is also comically buttoned with official hats.

Nono closed the oxygen valve and opened the mask slightly, and the patina-smelling air poured into his nasal passages, but he didn't feel suffocated.

"The air here is breathable, it saves a little bit of oxygen." Nuo Nuo patted Lu Mingfei, who was looking around.

"Chen Motong! Lu Mingfei! Please report back when you receive it! "Professor Manstein's communication came.

The two of them looked back, and the black rope that was integrated with communication and lifesaving was embedded in the bronze wall at this time, and Nuno reached out to touch it, and the black rope was already seamlessly connected with the wall.

"Chen Motong reported that we have successfully entered the interior of the Bronze City, and no one was injured, but there was a little accident." Nono reported, "The communication line is embedded in the wall. ”

Professor Manstein immediately gave a new directive: "You have an adapter cord in your pocket. ”

Lu Mingfei and Nuo Nuo connected the adapter cable and reconnected the communication.

"Call the Moniach, please answer if you receive it!"

"Moniach received! The signal is clear and there is no abnormality. Professor Manstein replied immediately.

"There is a situation that does not match the estimate, when Ye Sheng and Aki entered the interior of the Bronze City last time, the air was depleted due to perennial metal oxide, and the oxygen was exhausted, and it could not be used for breathing, but now the air quality inside the Bronze City can be used for normal breathing." Nono said.

"In the planned situation." Professor Manstein calmly replied, "Because the Dragon King has returned to his palace, the Dragons also need to breathe oxygen. ”

"Your next task is to place the bomb as close to the Dragon King's dormitory as possible, the main effect of this bomb is to react with water and metal, quickly depleting the air inside the Bronze City. The dragon king in the hatch felt suffocation and would burst out of the egg in advance, at this time he was very weak, and he couldn't even exert the strength of the second generation, which could be solved with a storm torpedo. The plan went well, and Professor Manstein gave the next instruction step by step.

"Understood, we're looking for a way." "The location we are currently in is a corridor with a lot of bronze statues of snakeheads on both sides. ”

"This is the Templar Path," said Professor Manstein, "and the Ice Sea Fragment records that the Templar Path was the only way for the ancients to meet the Dragon King, and this is the palace of the King of Bronze and Fire, and according to alchemy, the direction of the fire element is in the lower right corner, and the Dragon King's dormitory will also be in the lower right position, so you can see if there is water under your feet." ”

"Yes." The water here is about knee-deep.

"The Fragment of the Sea of Ice says that if you follow the current, you will reach the throne of flames." Manstein instructed, "Lu Mingfei, use the dye you carried. ”

Lu Mingfei pulled out a tube of dye from his pocket and poured it into the water.

The fluorescent yellow dye coalesced in the water, and it wasn't long before a line of yellowish light began to flow away against the bottom of the water, pointing the way forward.

The two of them followed the line, one after the other, through the snakeheads, and after they left, there was a sound of metal running in the corridor as if some mechanism had been triggered, and the snakeheads, who had been bowing and saluting, straightened up and looked straight ahead.

The Dye Thread was a useful guide, guiding the two through the labyrinthine corridors of the Bronze City, leading them to an open field.

The dye thread flows into a lake, a lake located below the river, and the magical structure of the Bronze City is truly amazing.

Lu Mingfei looked around, and the bronze dome was engraved with dense lines like giant trees, and Lu Mingfei certainly recognized it, which was the inscription made when the bronze city was built.

"This is where Aki Hakatsu has been." Nono said, "Do you remember that picture?" ”

"Is this the closest place to the dormitory?" Lu Mingfei said, "Let's hurry up and run away with the bomb." ”

"Don't worry." Nono shines the light on the surface of the lake, and the dye line plunges headlong into the lake that does not know the depth, and there is a terrifying feeling that the lake has swallowed everything.

Lu Mingfei understood what she meant: "Do you still want to go down and have a look?" ”

"That's right." "If the Dragon King's dormitory is blocked by this lake, then there is no point in us planting bombs here." ”

"Then let's go down and have a look." Lu Mingfei also nodded, and what Nuo Nuo said was reasonable and convincing.

The water of the lake is a dark blue, cold and clear, and the two of them can clearly see the surroundings after entering the water, it is a clear stagnant water, without any vitality.

"Ouch!" Lu Mingfei burst into a foul mouth.

"What's going on? Please answer, Lu Mingfei, please answer! Professor Manstein was shocked.

Nono turned the camera on the helmet, and when the image was displayed on the screen, everyone understood Lu Mingfei's reaction.

The bottom of the water is full of white bones, white bones belonging to human beings, thousands, they died here, buried here, and the bones have been precipitated for thousands of years.

"This is much more exaggerated than mass graves, a thousand people grave? Mass grave? Lu Mingfei said.

"Is it all over? When that's all that, let's move on. Nono shrugged as he pointed to the dye thread that had burrowed into the pile of bones, "Gather up the bones and see where the door is." ”

Lu Mingfei pulled away the layers of white bones with a bitter face, and muttered in his mouth: "Seniors, juniors are here to avenge you, no offense, forgive your sins." ”

Nuno rolled his eyes: "It's been dead for thousands of years, what are you afraid of?" ”

Lu Mingfei didn't speak, and he couldn't explain, after all, the soul is already an undoubted existence, who knows if there will be ghosts in this world?

After clearing the bones underground, the entrance of a "living spirit" guard was revealed underneath.

"Report to the Moniach, we have found an entrance underwater, which is suspected to lead to the Dragonlord's bedchamber." Nono reported.

"Good, keep exploring." Professor Manstein said.

Nuo Nuo took out another vacuum tube from his pocket, and Lu Mingfei's eyes widened: "How many copies of this thing do you have?" ”

"In order to avoid risks as much as possible, a total of five blood samples of the 'key' of this operation have been prepared." Professor Manstein explains.

Lu Mingfei couldn't help but praise the academy's thorough preparation, it seems that this dragon slaying plan is indeed inevitable.

Nono expertly smeared the blood sample on the lips of the living spirit, and the living spirit opened its huge mouth, and the water formed a whirlpool into the mouth, and the two of them held each other's hands and followed the current into the entrance.

Below the entrance was a smooth spiral slide, I don't know how long it had been sliding, Lu Mingfei felt that his ass had finally landed on something.

Looking down, the place where they landed was a huge bronze waterwheel, wrapped in a thick layer of strange fabric to form a comfortable seat, which may be more like an ancient Ferris wheel in terms of function.

The "Ferris wheel" sent the two to a bright entrance, and Lu Mingfei and Nuo Nuo jumped out and finally arrived at the destination of this journey.

In front of me was a hut, completely cast in bronze, but very simple, very different from the style of the other buildings in the Bronze City seen along the way, not so cold and brilliant, and the interior layout could even be called warm.

Illuminating the hut is a lamp, bronze texture, the shape of the palace maid kneeling, holding the lamp in one hand, and the sleeve of the other hand is on top of the lamp, forming a lampshade.

It was a Changxin Palace lamp, Lu Mingfei recognized it, he had learned it in history.

"Clever design, the oil is poured from underneath, and the smoke runs off the sleeve." Nono looked around the lamp for a moment, then reached out and picked it up, "Someone has added new oil to it." ”

The room fell silent, and Nuo Nuo and Lu Mingfei looked at each other, and they both exchanged opinions from each other's eyes.

If this is the so-called dragon king's dormitory, then who will add oil to this lamp?

The truth behind this incident is terrifying.

Lu Mingfei was silent for a while before he spoke: "Since the Dragon King is not here, do we still need to install bombs?" ”

"The communication line is cut by the entrance." "There's no way, let's load the bomb first, and then go back and connect the communication line to report the situation." ”

"Okay...... Okay. Lu Mingfei's face was a little unnatural.

Nono placed the black box he was carrying on the bronze table and opened it, and inside was a radio device that looked very old and 19th century.
