Faced with the overwhelming momentum, Ai Zheqin was calm and raised his right hand with two amplification rings slightly. The magic circle that had been prepared was suddenly activated, and a wind wall condensed into substance suddenly formed in the compression of the airflow.

At the same time, at the four corners of the gun mouth, the fire element that exploded was pulled and condensed by the power of the magic circle. In an instant, four three-ring fire rushing techniques were formed. Under the control of Ai Zheqin, they also attacked the fierce rock. The four fire rushes almost hit the same point, and burning flames bloomed in the heavy rain and the ocean.

During the explosion, the stone that was enough to smash a big hole in the wall of the ship was blown into pieces. Although it was still in decline, it lost the initial terrible kinetic energy. Countless fragments of all sizes hit the wind shield, and then were pressed down by an indestructible airflow and rebounded and fell into the sea.

After blocking this fatal attack, the advanced wind shield technique generated by the magic array finally exhausted its energy and began to dissipate rapidly.

"These sea tribes will not let it go. Next time, I'm afraid they can only rely on magic scrolls to hold on." Although Ai Zheqin's expression did not soothe much, "Frustrating the war whales is the key to blocking their attack on the deck. In this environment full of seawater, even the fire rushing technique cannot cause damage to this sea beast. Only the sixty-pound iron bullets of the ship-borne artillery are effective. The key to the victory or defeat of this trial is that these two cannons cannot be occupied or destroyed, otherwise we will have no resistance."

"The artillery matter is for me, the regiment commander."

The shirtless man who controlled the cannon laughed and used his left and right hands together. He used extremely skillful techniques to pull open the breeze of the two cannons at the same time and clean up the ash. Then he loaded gunpowder into the muzzle that was still emitting hot smoke and put the projectiles in. The whole process took less than a minute, and in this constantly bumpy environment. After doing these preparations, it inserted a fuse for the two cannons, ignited it, and then pulled them to two war whales in different directions, respectively.

There were two more cannons, and one of the two giant beasts floating on the water was pierced through the stomach, dyeing a large area of ​​sea water red in the churning, while the other one was knocked into the head with a solid iron bullet. After a few strokes, it stopped moving and slowly sank.

"It's great!"

The strong man shouted, through the not-so-large gun mouth, everyone around could clearly see that as several war whales were severely injured, the sea greyfish people on their bodies were sprinkled everywhere like ants, constantly ripping waves.

And at this moment, a member of the trial team who was covered in blood and in a mess rushed up from behind the lower stairs of the cabin.

"Captain Ai Zheqin, the situation in Tikuang is getting worse and worse. There are too many sea clans. The Seventh Team has been completely destroyed! We have retreated to defend the second-level cabin. Mr. Chai Linsel asked you to go down and discuss it."

"I understand. The first team stays here and continues to protect the artillery. Don't be stingy with your magic scrolls and equipment. All members of the second team will follow me to the base warehouse for reinforcement!"

"By the way, Commander Ai Zheqin..."

"Is there anything else?"

"Yes, a female member of the third team was missing, named Erin, who seemed to be one of the earliest members of the Trial Group. This happened before the Sea Clan attack, but we didn't realize it until just now that we were really ashamed."

"Oh? Then what about Reinhart, who have you ever met him?"

"No one, he might have stayed in the rest warehouse and didn't come out. The ship is so big. There are probably hundreds of rooms in the fourth floor cabin. We don't have the time to go one by one..."

"Okay, the most urgent thing is to support the bottom warehouse and let go of other things first."

"clear!"

A few minutes later, the lowest cabin.

Those magic apprentices who stayed on the deck happily swept monsters had not realized how much the deck had sunk in just half an hour, nor would they know how in the state the ship was floating in the storm, nor would they know that if the main force of the Trial Group had not kept the sea clan from the bottom of the ship, the entire ship might have fallen long ago.

There are four layers of cabins under the deck, and each layer is separated by a completely waterproof warehouse. When Ai Zheqin brought the members of the second team back to the third level cabin, the ground here was already soaked with deep water. In other words, the fourth level cabin, the deepest level under his feet, was already filled with sea water. Affected by the water inlet, the waterline of the ship rose. The third level cabin, which was originally only half immersed in the water, had completely entered the sea level. Through the waterproof observation port of the bulkhead, only a foggy color could be seen.

The hatch doors leading to the fourth floor were closed, but there was still constant water flowing upwards from the gap, and the color of the sea water became slightly reddish because of the blood of the gray fish man.

"Not too bad, at least we guarded these doors."

Ai Zheqin nodded.

The members of the trial team present gathered together, with nearly forty people. They exuded the aura of fighting, and magic glow was lingering around them, but the atmosphere seemed a bit heavy.

"Mr. Ai Zheqin, we have lost 18 members of the group. If this continues, it is only a matter of time before the third floor becomes as lost as the fourth floor." Seeing Ai Zheqin's arrival, the taciturn Chailinseer slowly said, "Have you heard the sound of corrosion from the feet? They have started to use dissolving monsters to deal with the cabin plywood again. We need to change our strategy."

"So Chai Lin, what are your opinions?"

"This is the home court of the sea tribe. They can have an absolute advantage in places where there is sea water. We only have this ship. It's only a matter of time before failure."

"Yes, I have heard that the sea tribe will never give up the prey they are targeting, as long as they are still in the sea." Ai Zheqin was walking in the shallow sea water and looked at the people around her and said, "Like the final trial in the past, we still have no prompts for what to do. The only goal is to live longer and achieve better performance. But I think that fighting with this ship to the last moment is not a great performance. Since the sea tribe appears, we must find a way to defeat it."

“It’s not easy.”

"It is normal that St. Peter's ultimate trial is not easy. Chalinsell, has the cabin of this ship been carefully searched?"

"Due to time, only the deck and bottom warehouse have been searched, and no valuable clues were found."

"Then keep searching. We don't have much time from this level, but it's worth it. Those magicians who made trials cannot just give us an empty ship with nothing."

A few minutes later.

"Prepare for battle, the cabin plywood can not last half an hour like the bottom of the ship!"

The "hiss" of the wooden board being corroded is getting closer and closer, and no one dares to stand on the ground anymore, because at some point, the severely corroded warehouse board may break due to overwhelming burden.

Water inlet is getting worse and worse. In such a giant ship, without the help of a magic water pump, this process cannot be stopped at all.

"Si!"

Suddenly, a burst of bubbles and white smoke emerged from the warehouse in the center. With the pungent sour smell, a small hole appeared and gradually expanded, and a soft-like green creature drilled out from it.

The corrosive monster of the sea tribe can secrete corrosive fluid that can erode ships in a short time. Although thanks to them, the ship that goes out to sea has gradually evolved into a steel shell, at least the ship that the trialists are in is not, so it is still easy to use. As soon as this sticky monster was exposed from the water, it was attacked by a large number of elemental bombs. Various light and shadow effects illuminate the water surface of the tumbling cabin. Unfortunately, it was half a meter below the water. The wind blade and fire tongue technique could not do anything to it, and could only scare it back to scare it who wanted to enter the cabin.

The corrosion continued, and it was obvious that at the bottom of the third cabin, there was far more than one corrosion monster at this time.

Soon, holes on the ground appeared one by one. Through the deep sea, the members of the trial group seemed to be able to see a lot of anxious figures in the cabin on the lower floor.

"Prepare for the battle, drag here for ten minutes, and then evacuate to the second deck."

"yes!"

Members of the two teams stood high and guarded the two hatch doors leading to the upper deck. The elemental shields were already ready, and the attack magic of each system was ready to go.

The silence lasted for a while. In the holes at the bilge that had been swallowed by the water for a long time, one after another of gray fish mermaids came in, and there were also several water monsters that looked like sea snakes from time to time.

Water magic took the lead in attacking. Under the manipulation of three magic apprentices, many vortexes of different sizes were generated by the cracked cabin hole. These conflicting turbulences caused the gray fish that charged towards the water surface to be terrified. The formation was disrupted for a while, but it did not cause any substantial damage in the end. Even with the increase in the marine environment, it was too difficult to kill the sea clan with the third-ring water magic.

"Condensing ice crystals!"

With a loud shout, several other members of the trial team who had already prepared had inserted their hands into the sea water, and ice silks rushed out radially. Unfortunately, the process was not fast. Under the suppression of the remaining magic apprentices, the wind blade and flame tongue technique, two minutes passed. Except for a thin layer of ice on the water, there was no degree that could effectively block the offensive of the sea clan. On the contrary, those sea clans kept trying to dock in the water and planned to emerge. As more and more new sea clans entered, this trend became increasingly difficult to stop.

But the ultimate purpose of ice-condensing magic is not to stop it.

"break out!"

Another loud shout came from the crowd.

When that was the case, several magic apprentices who were heavily protected and focused on turning seawater into ice crystals also increased their infusion of mana. The radial ice crystals around their hands suddenly shattered and exploded like hedgehogs. From the beginning, they had no intention of blocking the sea surface. With the strength of the magic apprentice, this was a fantasy method. All they were doing was to freeze the sea water into ice cones. The ice layer on the sea level was just an addendum condensed by the sea water when it encountered low temperatures.

Due to the resistance of the water, wind blades and fire rushes cannot pose a threat to the targets underwater. The sea clans gathered at the bottom of the bilge, but as long as they did not emerge, the magic apprentices above could not do anything to them. But if the physical ice cone in the water was launched like this, and it would be blocked by the water flow, the magicians who created them added continuous power to them. In this way, they only needed to maintain a steady speed to fly, and they could cause group damage that cannot be ignored, like sharp daggers.

The ice cone was colorless, and the flight under the water was silent, but about five seconds later, the magic apprentices standing on the water saw the bloody flowers bursting out from the bodies of the gray fish people and their desperate and confused struggles.

However, more gray fish people are still drilling into the hole, and they seem to be endless...

At the same time, on the second deck, Ai Zheqin was holding a letter that had been opened, and her face was not very good-looking.

"Are you sure, this was found in the place where Reinhardt has been?"

Directly opposite him, the member of the Trial Group did not dare to look up at him: "Just in the cabin over there, the cabin was covered with ice crystals, a hole was opened in the wall of the ship and blocked it with ice. Prince Reinhart had obviously left the ship!"

"Take me over."

When Ai Zheqin said these four words, although she was still calm and calm, she obviously felt a little angry in her expression.
Chapter completed!
