"Let's just set it for 45 minutes." Nono twisted the brass disc on the special bomb, and a small red light bulb began to flicker, "Time should be enough, the communication line is still outside, we can go out by following the line, it took us 15 minutes to get in, ten minutes to float, and 20 minutes to get back to the ship, enough." ”

"Alright, we've accomplished our mission." Nono clapped his hands and glanced at the room, "It's a pity, there's actually a lot of interesting information here." ”

"Stop talking nonsense, let's go." Lu Mingfei urged.

The two of them turned around and jumped on the other side of the bronze waterwheel, ascending to the top, where there was a bronze relief of a human face, and after consuming a tube of blood again, the relief opened a hole as if it were melting, and carried them up with a great suction.

Seeing that he had returned to the bottom of the lake before, Lu Mingfei said, "Hurry up!" ”

"Where are you going?" Nono asked, "The communication line is missing...... Someone took it away. ”

This terrifying speech made Lu Mingfei's hair stand on end, and he reluctantly spoke: "Except for the two of us here, there is only the Dragon King left, the Dragon King can't do this, right?" He shouldn't be able to kill us both. You say that as if you were haunted......"

Nuno ignored Lu Mingfei's words, she looked at the pressure gauge and said, "The water pressure has become smaller." ”

Lu Mingfei saw that the water pressure had indeed decreased by half, and it was still dropping, which showed that the water above their heads was continuing to become shallow.

Listen closely, the sound of the machine running is gradually getting louder, and the sound of the metal gear biting and rotating slowly turns into a thunderous roar.

At this moment, Lu Mingfei's face became extremely pale, and he reacted before Nuo Nuo: "Bronze City...... Moved. ”

During the collapse, Lu Mingfei looked up, the bronze gear as big as a grinding disc was constantly falling, and the entire water body was stirred, and then a large piece of bronze fragment also fell into the lake, which could be vaguely identified from the pattern on it, it was the bronze dome above.

"It's self-destructive, his grandmother's, Norton, you're so ruthless!" Lu Mingfei gritted his teeth in anger.

By this time, it was basically certain that the target they were looking for would never be in this Bronze City at this moment.

"I can't go up there, go down there!" Nuo Nuo couldn't help but say, pulling Lu Mingfei back to the Dragon King's bedroom from the original way.

The water was pouring wildly, and after a while, there was a sound of the ground shaking from above, and the house below also began to shake, and it looked like it would collapse at any moment.

Lu Mingfei said calmly: "Follow me, I remember the map." ”

Only then did Nuo Nuo remember that Lu Mingfei had also deciphered the map of the Bronze City, and said suspiciously: "Do you remember the map?" ”

"Of course I remember what can save my life." Lu Mingfei said, commanding, "Let's dive down now." ”

Nuno didn't bother with the words "listen to my command" before going into the water, she didn't hesitate to dive behind Lu Mingfei.

On the river, there was a dead silence in the command room of the Moniach.

Fifteen minutes earlier, the underwater group had lost contact for unknown reasons, with both Professor Manstein and Caesar glued to the surveillance screen, but so far nothing has been heard.

"It's been fifteen minutes, and the chances of survival are very low if you lose contact in this situation." Professor Manstein said.

"Now it's time to send a second group down." Caesar said, his tone like an emotionless robot, "I can dive alone, or I can draw from other people, and they have enough oxygen to hold on for at least an hour and a half, and death cannot be confirmed until the oxygen is exhausted." And they must have had important information when they encountered unexpected circumstances. ”

"Do you know what my spirit is?" Professor Manstein said, "My spirit is the same as Ye Sheng, I am a 'snake', my domain is three times larger than Ye Sheng, and I can go straight to the bottom of the water, which is why I will lead this operation." ”

Professor Manstein stared into Caesar's eyes for a long time before he said, "You feel it too, don't you?" Sound travels faster in water than in air, what does your 'sickle' hear? ”

"Noise, very scary noise." Caesar replied.

"I can't tell what's going on down there, but it's very likely that the Dragon King has been alarmed, so we can't dive down now, act according to plan, our goal is to kill the Dragon King." Professor Manstein said coldly, "We are waiting for him, Caesar, to complete our mission." ”

Caesar didn't say a word, staring at Professor Manstein until a student council officer came up and pressed him on the shoulder.

Professor Manstein glanced at his watch: "I see fear in your eyes, Caesar, but don't worry, if they live, the oxygen will last for an hour and a half, and after an hour, I will give you permission to go down to the rescue." ”

"Look outside!" Someone exclaimed and pointed out the porthole.

I saw that the outside was now surrounded by vast white steam, and the visibility was reduced to below the dense fog, and the vicinity of the Moniach was like a boiling pot, steaming out the white vapor as thick as milk.

"Here he comes. Norton, the Lord of Bronze and Fire, whose high temperatures heated the surrounding water bodies, causing an excess of steam. Zero said, "It was a premeditated hunt." ”

"Then now everyone is in place." Professor Manstein clapped his hands, "Kids, get moving!" ”

All the members were in their positions, Caesar loaded the bullets into the magazine of the sniper rifle, which was the alchemy ammunition prepared by the armament department, the Moniach was indeed different from the last time, they were fully armed this time.

The hull of the ship shook, and a muffled sound came from the bilge.

"The torpedo compartment was attacked! The warhead is destroyed! The first mate reported anxiously.

In the torpedo bay, the first mate watched in disbelief as a huge serrated saber broke through the torpedo bay and severed three alchemy warheads in a dashing manner.

After a succession of bad news, after the torpedo compartment, the watertight compartment was also attacked, and two of the six watertight compartments of the Moniach were leaked in an instant, and if two more leaked, the ship would lose its buoyancy and sink.

"Start the engine immediately and accelerate, and standing still will only be a target." Undeterred by the flurry of bad news, Professor Manstein gave the order as soon as his face sank.

The Moniach roared its engines and sailed in a zigzag pattern across the river.

In the underwater bronze city, it is a little difficult to shuttle through the rapids, Lu Mingfei and Nuo Nuo struggle to move forward, every passage and space here is changing every second, but Lu Mingfei's movements are firm, as if he knows this place well, and he can always find the way out in the incredible gaps.

"It's going to be the end soon, and the exit is there." Lu Mingfei's eyes had already lit up with hope.

Nuo Nuo looked in the direction pointed by Lu Mingfei, there were bronze walls on all sides, only the bronze wall directly below had a hideous face relief, which was another living spirit.

Nono breathed a sigh of relief, pulled out the last tube of blood and was about to step forward to open the living spirit, above his head, the bronze wall was pressing, this bronze city was completing its final disintegration, and there was not much time left for the two of them.

"Be careful!" Lu Mingfei rushed over and knocked Nuno away.

Nuo Nuo was knocked out, the vacuum tube in his hand fell, and he looked back at Lu Mingfei, who was holding his left arm with his right hand, where blood rose like ink smoke with bubbles at the bottom of the water, and on the bronze wall not far away, a short knife shaped like a rib was nailed to it.

"His grandmother's still has this insidious trick." Lu Mingfei said softly, "I miscalculated." ”

"The blood sample was shattered." Nono swam over and said, "But if the purity of the bloodline is not enough, you can also open the living spirit by sacrificing a large amount of blood, and the consequence is blood loss and death. This method of opening the Dragon Clan's secret palace has been documented, and it is forbidden in the academy's operation manual, so it is not recorded. ”

Lu Mingfei knew what Nuo Nuo wanted to say, and he immediately interrupted what Nuo Nuo was about to say: "I will take you back." ”

Nuno looked into Lu Mingfei's eyes, and in them was what she felt but couldn't understand in several profiles - confidence.

Lu Mingfei took out a bandage from his bag and tied his arm tightly to prevent oxygen from leaking out, and then he raised his right hand, and a gorgeous ancient sword appeared.

As soon as this sword appeared, it had a strong temperament that even the heavens and the earth were overshadowed, it was gorgeous but not vulgar, splendid but not chaotic, and it was a noble sword at first sight.

It is the ninth sword rank, the sword of the noble and unparalleled, pure Jun.

Lu Mingfei pointed at the living soul with the pure Jun sword in his hand, the sword shadow flashed in his eyes, and he exhaled: "Open!" ”

This sentence was just like a heavenly constitution in his mouth, and he gave a decree with a noble and unparalleled momentum, and the hideous living soul actually showed a look of awe on his face, and then he really opened his mouth and opened his mouth.

Lu Mingfei pulled Nuno and rushed out of the exit, the bronze wall behind him collapsed, and this glorious bronze ancient city finally turned into ruins after being silent for a thousand years.

"Why hasn't our sonar found any trace of the Dragon King?" Professor Manstein yelled, "He's so close to us!" Gunayar, check the sonar! ”

The second mate, Gunayar, activated the sonar self-test, and then looked horrified: "Report to the captain!" The self-test program is displayed...... Our sonar transmitters were also destroyed! ”

"Dragon King Norton!" Professor Manstein roared, "What a cunning fellow! ”

The draft of the Moniach is getting deeper, the destruction of the watertight compartment is by no means without effect, they will not support it for long, if one more watertight compartment is broken, they will all sink, the crew is anxiously trying to find a way to repair and extinguish the fire, the diving bell has been put down, but this thing is equivalent to an ornament, who dares to launch near the dragon king?

Caesar pondered, and suddenly he raised his hand and said, "Report to the captain, I have a proposal!" ”

"Say!" Professor Manstein said with a stiff face.

"I applied for a storm torpedo with a conventional warhead." Caesar said.

"Why?" Professor Manstein asked, "Caesar, you should know that conventional warheads are ineffective against the Dragon King, and the armament department has also dismantled the explosive part of conventional warheads. ”

Caesar calmly replied: "The speed of the storm torpedo can reach 200 knots, as fast as an airplane, the length of a conventional warhead is 8.23 meters, its own weight is 2700 kilograms, and at the speed of an aircraft, as long as it hits head-on, no living thing will survive." It's okay without an explosive unit, just use it like a cold weapon. ”

Professor Manstein thought for three seconds and said: "The theory is feasible, but the speed of the storm torpedo is too fast, and it can only shoot directly without legal guidance, and Norton did not give birth to a huge dragon body as we expected, and the size is too small to ensure that it hits the target, which is why we use an alchemy warhead, it is too difficult to hit directly, and the special alchemy blade of the alchemy warhead can be deployed to have a lethal effect." ”

"Captain, let's work together to lock down his position, and then you can order the launch." Caesar said.

This was undoubtedly a bold plan, and Professor Manstein pondered for a moment before saying, "If you want to hit him with a storm torpedo, you must fire it at a very close distance, and with his size, this distance cannot exceed thirty meters." ”

"Then let me fight for the thirty meters." Caesar gestured to the sniper rifle in his hand.

"Yes, approve the action." Professor Manstein nodded, then ordered, "Zero, you come and launch the torpedo." ”

"Yes." Zero replied.

"Don't use the 'Sickle' when a storm torpedo is fired, it's a supercavitating torpedo that makes a loud noise when fired and will destroy your eardrums in an instant." Professor Manstein admonished.

Caesar waved his hand to show that he understood, and then walked to the deck with his sniper rifle on his back.

Caesar blindfolded himself with a handkerchief and used the Scythe to lock on to the enemy, and soon he locked on to a hidden heartbeat, and he immediately fired the first shot.

Hit! The distance between the target and the Moniach was less than 300 meters, because his speed under the water was not as fast as that of the Moniach, and he was somewhat unable to catch up.

Caesar knew it wouldn't do any harm, Caesar knew it, but it didn't need any harm, his goal was to provoke the dragon king's wrath, and anger would bring impulses.

"The speed of the ship slowed down and slowly approached the goal." Caesar said in the communication channel.

Caesar continued to fire, hitting accurately, and a dazzling light radiated from underwater, just like the first generation of the Kassel Academy that day, the enraged dragon king unleashed his words and revealed his location.

"Rush straight at him!" Professor Manstein commanded decisively.

With a distance of less than 300 meters, to be shortened to 30 meters, the Moniach will only need eight seconds at full speed, and there is only one chance.

"Launch!" Professor Manstein ordered.

Zero pulled down the launch gate, the hull of the Moniach shook, and a sound exploded, and the conical storm torpedo shot like a bullet out of the water towards the small sun in the water.

Even if Caesar revoked the Scythe, the manic sonic boom could still be heard.

At a distance of 30 meters, it takes less than 0.3 seconds for a storm torpedo with a speed of 200 knots to wipe out, and it undoubtedly hits the target, and the huge kinetic energy carries the target forward and is submerged in the water together.
