Professor Mance immediately greeted him, and he saw Ye Sheng and Aki swimming towards him, Ye Sheng had a rope tied to his waist, and on the other side of the rope was a brass jar about a man high.

Professor Mance was filled with a huge surprise, and his good students not only survived, but also won an unexpected victory!

Professor Mance hurriedly reconnected the signal line and lifeline to Ye Sheng and Aki, changed the oxygen, and reported to the Moniach at the same time: "Report to the Moniach, this is Mance, and Ye Sheng and Jiude Aki have been successfully contacted, everything is normal!" ”

The signal line conveyed the command on the Moniach: "Moniach received, please confirm to fasten the lifeline and return immediately." ”

On the Moniach, the engine that retrieves the lifeline turns quickly to pull up the three elite specialists who work underwater.

Sitting in the command room of the forward cabin, Ange stared deeply at the changing sonar map, when suddenly he pointed to a shadow on the map and said, "What is that?" ”

The second mate was startled, and looked carefully, it was a huge shadow, which was rapidly approaching Professor Mance, and hurriedly reported: "The length is about fifteen meters, and the speed of movement is close to 50 knots, it looks like a fish!" ”

"You're joking," the third mate immediately retorted, "Fifteen meters is outrageous enough for a fish to swim at fifty knots?" It could never be any kind of fish! ”

Ange stood up, with a cold murderous aura in his eyes: "That's a dragon, remind Professor Mance that there is a big guy catching up behind and starting Plan C." ”

"Yes!" The correspondent nodded.

"Professor Mance, please pay attention, there are giant unidentified creatures suspected of being dragons approaching you, Plan C has been opened, please be safe!"

Listening to the reminder from the signal line, Mance looked at Ye Sheng and Aki, smiled, there was no worry on his face, and he communicated with them through the signal line: "You two little guys are blessed, even I haven't seen the picture of the headmaster's shot a few times." ”

Ye Sheng looked back, and then said, "This time, the principal may not take action personally, I heard that the principal brought some good things when he came this morning, just to deal with such a situation, right?" ”

"That's good stuff indeed." Professor Mance nodded, "'Storm', the fastest torpedo in the world, can reach an underwater speed of two hundred knots, and the equipment department uses it to carry an alchemy warhead, I don't know how it will be against the Dragon King, but it is expected that one shot will be enough to blow the next generation in half." The headmaster said that no matter what monster we are going to face, we must destroy it under the water, so that it does not cause any sensation when it comes out of the water. ”

Ye Sheng was terrified: "Can we still survive after that hair?" ”

"If we get too close to it, we probably won't survive," Professor Mance said. ”

"Then we'll have to hurry up." Ye Sheng pointed down, "I've seen it." ”

Professor Mance looked in the direction Ye Sheng was pointing, and also saw the uninvited guests chasing after them.

It was a behemoth, its slender neck covered with black scales, its back like a steep mountain rock with hideous black bone spurs, its huge skull covered with an ancient iron mask, and a pair of strange golden pupils only visible from the part of its eyes.

It was the first time Ye Sheng and Aki had seen such a creature, it looked powerful and extraordinary, and there was no doubt that there was only one word to describe it, that is, "dragon".

Countless bubbles rose from the gaps in the black scales of the giant beast, and Ye Sheng looked at Professor Mance: "Professor, do you feel that the water temperature seems to be getting higher?" ”

"I feel it," said Professor Mance, "it's not surprising that a dragon of the Bronze and Fire veins has such abilities, and its target should be the copper pot. ”

Hearing this, Ye Sheng pulled the copper pot tied by the rope to his side and hugged it tightly.

The dragon in the distance seemed to be enraged by Ye Sheng's movements, its mouth opened wide, and the boiling water squirted towards Ye Sheng with bubbles.

Professor Mance chanted a spell and opened the dust-free space, rapidly forming bubbles blocking out the hot stream of water.

"Underwater warfare is too inferior, and I'm no match for it." Professor Mance shook his head, "Get on board." ”

"Professor, but we don't seem to have enough time?" Ye Sheng's face turned pale, "It's about to catch up, if it gets too close to us when we get on the boat, with the killing radius of the 'Storm' torpedo, will we all have to be buried with it?" ”

"Less nonsense." Professor Mance glanced at Ye Sheng, "Even if we can't get rid of it, as long as we buy enough time, there will always be a way." ”

Ye Sheng stopped talking, he stretched out a hand and leaned out of the range of the Dustless Land, feeling that the temperature of the water around him was getting higher and higher, which meant that the dragon was getting closer and closer to them.

Those strange golden pupils were like two small lanterns, which made people's hearts palpitate, and Ye Sheng's gaze gradually became firm.

"Professor, I have a solution." Ye Sheng opened his mouth and said.

"Say." Professor Mance stared intently at the black dragon that was getting closer and closer.

"If you want to buy time, you have to find a way to stop it, one person to hold it down, and the rest of the people have a chance to leave." Ye Sheng said, "I also have a prop that can destroy this 'egg', this is a backup option, but its killing radius is twenty meters, I'll ...... it."

"I'll hold it back, and you take the eggs back to the Moniach." Professor Mance interrupted Ye Sheng's words, "This is the best arrangement. ”

"Professor!" Ye Sheng and Aki both lost their voices.

"My spirit of words is better suited to battle." Professor Mance looked at his two students, his gaze softened slightly, "I'm more able to take on the task of delaying time, you are still young, with me here, it is not your turn to sacrifice." ”

"Say hello to Nono on my behalf, it's time for her to change mentors." Professor Mance untied the lifeline and smiled, "When you go back, resign from the Underwater Operations Department in the Executive Department, so that you won't be restricted by that shit rule, I'm sorry I can't attend your wedding, goodbye, you're my pride." ”

Ye Sheng watched Professor Mance let go of his hand and turn around and swim in the opposite direction, he clung to the copper can, his teeth clenched, and he couldn't say a word.

Professor Mance faced the black dragon rushing straight ahead, holding a special underwater pistol made by the Equipment Department in one hand and an alchemical folding knife specially made by the Equipment Department in the other.

The boiling water of the river with boiling bubbles hit the barrier of the dustless land, and the black dragon rushed up at a speed, and there was no such self-sufficient little human in its eyes, it would not make way for anyone, and everything that stood in front of it would be ruthlessly crushed by it.

"It's really underestimated...... Professor Mance pulled back his mask and stared at the pair of golden eyes in front of him, his eyes also flashed with a faint golden glow, "Burst blood!" Speech Spirit, Dustless Land, give me ...... Stop it! ”

The river surrounding Professor Mance swirled violently, forming a transparent barrier that suddenly expanded to ten meters, forming a vortex that swirled at high speed.

The black dragon burst headlong into the vortex, and in the midst of the extremely fast water, even it had to slow down, and finally, it slowly stopped in front of Professor Mance.

Anxiety and anger appeared in the pair of demonic golden pupils that had been indifferent, and it spread its dragon wings like a sharp knife slashing at the vortex barrier.

With a "pop", the barrier of the Dustless Land shattered, and Professor Mance quickly retreated, unfurled his speech again, and raised his hand to shoot at the black dragon's lantern-sized golden pupils.

The bullet was fast, but the dragon wing was faster, and it blocked the alchemy bullet in an instant, and then the black dragon shrank back and was about to chase in the direction of Ye Sheng Aki, its goal was only one from beginning to end, and it would never waste time on the little bug Professor Mance.

Professor Mance knew that he was not swimming as fast as the black dragon, which had accelerated at full speed of fifty knots, but he would never give up, and he would pounce forward, grabbing the bone spurs on its back, and never let the black dragon have any chance of escaping himself.

The black dragon was so hot that Professor Mance felt like he was about to be burned through the nanomaterial wetsuit, but he still clung to the bone spur and didn't let go, while his other hand kept firing fire, killing all the bullets in the magazine.

The bullet that hit the skin was finally a success, and a piece of dragon scales was shattered, and the alchemy bullet stuck into its skin, and wisps of hot dragon blood oozed out.

This level of injury can only be regarded as a skin wound at best, but the alchemy bullet is not so simple, and the special alchemy toxin has slowly penetrated through the warhead.

As if feeling a small piece of skin on his back become painful and numb, the black dragon roared, and the dragon wings spread out, sweeping around on his back, trying to sweep the hateful little insect down.

Professor Mance dodged and used the dustless to fend off the dragonwing's attack, discarding the depleted pistol and pulling out his alchemy knife and stabbing it through the black dragon's wound.

The black dragon roared angrily, its scales suddenly opened, hot bubbles rushing out of the surface of its skin, and Professor Mance could feel its body temperature rise again, it was not like the surface of a living being, but more like a boiling boiler.

Professor Mance was burned to the core, but the black dragon didn't stop, and neither could he!

The alchemy knife stabbed at the black dragon's wound like garlic, and Mance knew that this was just a drop in the bucket, and the length of the knife was not enough, maybe it didn't even pierce the black dragon's skin, but he had no choice but to keep attacking.

At this moment, the black dragon paused, and suddenly began to spin his entire body, Mance's actions were not useless, at least the alchemy folding knife pushed the alchemy bullet deeper into the depths, even the huge black dragon could no longer completely ignore the impact of the alchemy toxin.

Professor Mance was almost shaken off, but it wasn't that easy, he took out a rope, made a simple noose, and went towards the bone spur sleeve in front of him, and then used the power of the black dragon when he turned around to jump up, towards the bone spur in front of him, moving the position step by step, his target was the position of the black dragon's neck.

It is said that when the dragons under the first generation showed their dragon bodies, there would be a scale growing backwards on the back of the neck, and as long as they attacked that place accurately, the dragon would fall into a state of madness, which is the so-called "dragon has reverse scales, and it will be angry if you touch it".

Grabbing the last bone spur in front of his neck, Professor Mance was already a little exhausted, and he gasped and looked ahead, the scale that was growing backwards not far away.

Professor Mance was engrossed, unfurling the dustless ground to cover the scales, and threw the folding knife in his hand with all his might.

The folding knife hit the reverse scale with unmistakable accuracy, stuck in the gap between the scales.

The black dragon finally stopped, and a terrifying aura evaporated from its huge body, and the excessive amount of high-temperature water vapor and water rushed Professor Mance down in an instant, and if it weren't for the protection of the dustless land, this time it would have given him a third-degree burn.

It hadn't been long, but Professor Mance had been exhausted by the frequent use of words, and now he was unarmed, but he had managed to stop the black dragon, and he was ready to accept the fate he was about to face.

Professor Mance put on his diving mask, and his whole body relaxed, allowing himself to sink, facing a mad dragon, he had absolutely no reason to survive.

Professor Mance stared at the black dragon's golden eyes, which were only mad, and suddenly felt like the surroundings were much quieter.

Looking closely, the black dragon's movements have become much slower, and even, not as fast as his own fall!

Professor Mance stopped falling and swam upwards with all his might, his eyes filled with hope once more!

Sure enough, after more than ten meters upstream, Mance saw a figure from a distance that made him excited.

Principal Angers in a diving suit was there, and everything around him seemed to slow down many times, only Professor Mance and Principal Angers in front of him moved freely.

The famous Italian writer Calvino once recounted such a scene: the lion pounced on the hunter, and the hunter shot an arrow, and this moment was like a freeze frame in a movie, presenting an absolute time, that is, "Time Zero". The events that followed entered time 1 and time 2...... And before the lion pounced and the arrow was shot, it all happened before time zero, that is, time minus one, time minus two......

This situation is like the absolute "time zero" that is frozen, and this is the powerful spirit of Hilbert Jean Angers, the current president of the Kassel Academy, the most prestigious elder of the dragon blood, and the leader of the secret party.

Time Zero.

Professor Mance swam up to Headmaster Ange and connected the signal line, to which Ange nodded slightly, "You're doing a great job, Mance." ”

Professor Mance smiled, "Thank you, Headmaster, I thought I was going to die here, let's go back to the ship, shall we?" ”

"Don't worry, Mance, you don't mind watching an underwater fireworks show, do you?" Ange smiled.

Time returned, and Professor Mance jerked back, and a huge torpedo flew past him, heading straight for the crazy black dragon in the distance.
