"Watch out for impact!"

As soon as Jiayi's voice fell, there was a "bang" sound, the hull of the ship shook for a while, Jiayi was unstable in front of the workbench, and his forehead hit the workbench directly, breaking a large piece of oily skin, and the person was also thrown to the ground.

He told others to be careful, but he didn't sit still.

There was a panic on the deck, although Jiayi gave a reminder, but the interval was too short, and they were hit as soon as they heard it, and they were not mentally prepared. It's not that Jiayi's reaction is slow, it's just that the speed of these mutant fish is too fast, and the action of turning underwater is too fast, so people don't have time to react.

Fortunately, the people on deck had prepared before they could stop the fish, and although the impact was thrilling, no one fell overboard.

But this impact, of course, will not cause nothing, only the people in the lower part of the cabin are heard shouting again: "Leaking, come on, leaking." ”

And after the impact, the team leader already knew that the bottom of the ship would break, and before the people below could start shouting, they began to send to endure and go down to repair the boat.

But before the dispatched men had gone down to the bottom of the boat, Kaichi's voice came again: "Be careful, they are going to make a second impact." ”

"Jiayi, can you tell me some good news next time. Husley felt that nothing good was good every time Jia Yi spoke, and as soon as his words fell, there was another violent impact, and his feet slipped and he sat down on the deck.

There were too many mutant fish this time, and they were divided into several batches, so after the first impact, there was a second, even a third, and a fourth. And through sonar observation, after the fish hit the plank, the fish hit the coma, but a small number of fish showed signs of waking up, much faster than the other fish.

If it is a "swordfish", it will be very easy to stick the sword above its head into the board of the ship with each impact, and it will not be able to break away from it, so it will not be able to attack again. But the "head hammer fish" is different, he will talk about the board every time a big hole is hit, and the "head hammer" seems to have a shock absorbing effect, after each impact, only a certain amount of recovery time is needed to move again.

Jia Yi didn't understand why for the time being, but this didn't affect his judgment, if it continued like this, the speed of replenishing the ship would definitely not be as fast as the destruction of the group of things below, and their team would probably be cold.

After the second impact, only 3 or 5 minutes later, the ship's waterline was lowered by at least 10 centimeters, and the cabin had an accident.

"Husley, a tiger fish has come in the cabin. A classmate who was patching holes in the cabin shouted.

"What's going on?"

"These tiger fish were so crazy that as soon as the boat broke holes, they rushed in, and we didn't notice that several sailors were bitten, and one of the big toes was bitten off. ”

"Is it under control?" said Husley, frowning and going under the cabin, trying to contact the teacher of the large army through the badge, but there was no response.

"It's under control. The student who came up to report the letter replied, "The loophole has been plugged for the time being, and now it is being drained outward, fortunately, there is a watertight cabin, otherwise the water intake is at least several times more now." It's just that if we continue like this, I'm afraid we won't be able to plug it, and now we won't even have enough planks to plug the leak. ”

The sailors were not like mages, they were protected by shields at all times, and in a panic, they were bitten before they could spot the tiger fish swimming in.

"The planks are not enough, so we can remove them first and block this wave. ”

As soon as Husley reached the bilge where he had just been hit, the ship was hit again, and right in front of Husley, a fish "banged" through the deck, and then sank again, and at the same time a swordfish rushed out of the hole with a "bang", and rushed straight towards Husley, and as soon as Husley dodged, the fish rushed over, and then shot into the bulkhead of the cabin, embedded in it, and could not get out.

At the same time, as the water poured in, mutant tiger fish also swam in and rushed over as a person.

Husley hurriedly blocked the hole with a spell, and at the same time went out along the hole, all the water that came in turned into an ice lance, and the tiger fish in the water was also pierced by the ice lance, and the blood was frozen before it could flow out.

Husli hurriedly contacted the rest of the ships, not only their ships were broken, all the ships were hit, but Jiayi and their ships were in the middle and suffered the most serious impact. Fortunately, there were no casualties, the most serious being the hapless sailor on Husley's side who had his big toe bitten off by the tigerfish.

Fortunately, the big toe is not as important as the thumb, and although it affects the balance, the wind and waves on the inland river are not as high as those at sea, and the requirements for sailors are much lower.

After Husley had inquired about the loss, he asked Passerbai through the badge, "What should I do now, can you contact the teacher?"

"I tried, but I can't get in touch. Paser shook his head, remembering that the other party couldn't see it, "I also asked the rest of the people, and everyone couldn't get in touch, and the distance should be enough now, but there seems to be interference." ”

"So what to do now, I can only rush hard. Hopefully, our boat will hold out until it reaches the teacher. ”

"Is it okay to rush hard? or let's go into the water and kill them in a wave, or put a shield on the bottom of the boat. Paser Bai suggested.

Husley thought for a while, but still denied: "There are too many tiger fish underwater, and these tiger fish are mutated, as long as they are in the water, the shield will be bitten through for a while, and the shield is not feasible at all, not to mention whether we have the ability to add a shield to the entire bottom of the ship, calculate and add a shield, the resistance becomes larger, we can't walk, and we become a live target." ”

They were discussing here, and Jia Yi was also anxiously trying to figure out a way, because he saw that some of the "head mallet fish" had slowly woken up, and it seemed that it was slowly accelerating, and then accelerating, and the next wave of attacks was coming.

Kaichi suddenly remembered dolphins, which can also emit ultrasound, and the ultrasound of dolphins can distinguish different species of fish, and not just by the outline of the fish. Moreover, when dolphins are hunting, they can use high-intensity ultrasound to stun the fish.

Thinking of this, Jia Yi glanced at the sonar in front of him, and immediately maximized the cluster function of the sonar, and at the same time adjusted the sonar power to the maximum, and attacked a school of fish with a sonar.

Sure enough, after receiving the high-intensity sonic blow, the group of fish immediately became swaying, although they did not faint, but their movements became inflexible, especially some relatively small fish, their bellies turned up and began to float upward.

Jia Yi hurriedly informed the rest of the sonar operators: "Everyone said that the sonar is aimed at the fish, the cluster is opened to the maximum, and the user's maximum power is launched at the fish, which can strike at the fish. ”

Originally, everyone was panicking, and when they heard Jiayi's words, although they didn't know why, they held the mentality of giving it a try, and followed Jiayi to target a school of fish that had just woken up, and everyone adjusted the power together.

"One, two, three, launch!"

As soon as Jiayi's words fell, in an instant, the fish that were targeted were like being beaten by a stick, swaying left and right, swaying and swaying, wanting to escape but not having the strength, and after a while, they were belly up, motionless.

"It's done!" Kaichi clenched his fist and loudly announced to the rest of the group, "It's okay, the sonar ultrasound cluster can kill the fish underwater, don't worry about these damn fish now." ”

"Yes, Jiayi, you finally didn't say any disappointing news this time. Husley's voice came, and Jiayi always reported dangerous situations in front of him, so that Xiusli and they didn't dare to listen to Jiayi, and every time Jiayi opened his mouth one by one, they would feel that there was something wrong again.

"That's not my problem, it's just that I'm the first to speak, gather together, and do a few more times, and knock all the fish out. "Even if these sonars are combined, they can't kill these fish, they can only stun them, but this time there is no need to worry about these fish waking up and killing them again.

When Jiayi and the others stunned a batch of fish with ultrasound, the rest of the fish seemed to sense the danger, wagged their tails, left a string of bubbles, slipped away, and swam away.

The ultrasound waves emitted by the sonar, even if they converge, will spread to the surrounding area, and the fish can no longer stand the sound of the sonar, and they flee before the blow falls on them.
