Xiao Tuanzi stood on the high platform and looked at the people on the deck below.

Small blackboard: Each group of ships takes turns to drive. Drive at 33 knots and keep moving at a constant speed. Rotate every twenty minutes!

The crowd looked at the contents.

33 knots, one knot is equal to one nautical mile per hour, which is equal to 1.852 km/h.

Thirty-three knots is equivalent to 61.116 km/h.

So that means they need to follow the boat underwater so fast.

Isn't that fast?

Not very quickly, of course, in the selection of soldiers in some countries at the beginning of the naval war, there were three grades.

At the highest level, the conditions are to jump into the water from a height, cut your foot first, swim 25 yards underwater, swim breaststroke with freestyle, swim 220 yards in backstroke, be able to rescue a drowning person and swim at least 25 yards.

One yard is equal to 1km/h.

220 yards is equivalent to 220 km/h.

Now the physical fitness of everyone present has far surpassed that of previous humans.

Xiao Tuanzi's choice of 33 knots is the reason for weighing many aspects.

Now it's not just swimming, you also need to fight zombies that don't know where they will come out of the water all the time.

It will also be necessary to dive to the bottom of the ship to prevent counterfeiting.

It's not that you can swim on the surface all the time.

But they can directly and flexibly change their status.

It's not like one or the other all the time.

As for underwater fighting, most of the people here have also been trained.

So Xiao Tuanzi thinks it's feasible.

The previous storm had changed their course a lot, and now it took more than an hour to get there.

Each set can be trained at least once.

Xiao Tuanzi has to find out what she wants to know from their performance.

Then, when I took those people back later, I studied them slowly.

The training soon began.

The first group of people jumped down one by one very consciously.

Of course, they also did a good job of distributing the work before they went into the water.

The little group came to the boat string and entered the water without hesitation.

In fact, when I saw the small group entering the water, the people next to it were very surprised.

Because cats haven't always hated water?

How about this one?

However, in their previous training, they also participated in the dogs, so they were just surprised for a while.

The cold sea water will wrap the body of the person who is like water.

It is also because of the navigation of the ships, which causes waves in the sea.

It also made it more difficult for them to march.

In this case, there is no way to open the eyes.

Xu Xing also followed into the water, and the rule he gave himself was to stay in the water for half an hour.

Of course, Xiao Tuanzi will not object to anything.

In fact, they have experienced this kind of boat trip before.

A very normal project.

In the water, Xiao Tuanzi chose to take care of the bottom of the boat.

This is already about ten meters of seabed, of course, this is not the draft of the ship, the draft is a little deeper.

But in order to protect it, of course, you have to be two or three meters away from it.

In the water, Xiao Tuanzi did not open his eyes, nor did he use mental power, but used perception.

Use your body to feel the flow of water throughout the seabed.

In this way, you can sense something that is attacking you.

This one is hard.

Her ears were also tucked away by her, so that the sea water would not pour into her ears.

Of course, some voices can still be heard. But at the bottom of the sea, after getting used to the propagation of sound in the air on land, in the sea, it feels a little weird, like seeing flowers in the fog.

Sense the rapid flow of water.

The little ball wants to stretch out its claws, but the resistance and pressure at this depth are very high.

Her speed has slowed down significantly, and what can be done with one claw can be done with two paws.

Because of the action, the oxygen in Xiao Tuanzi's body was constantly lost, and after thirty minutes, the feeling of suffocation came to the brain.

If she doesn't breathe in time, then there is a good chance that she will have a brain injury!

Xiao Tuanzi resolutely floated upwards and let others take his place.

Breaking through the water, he took a few deep breaths and plunged down again.

Xu Xing had already climbed the rope to the deck at this time.

He was so tired that if it weren't for a belief that sustained him, he would have sunk to the bottom of the sea.

See a figure fleeting on the sea.

A look of admiration flashed in his eyes.

Everyone here rotates the bottom of the boat every minute because they can't hold on for that long.

You can only do it in a repetition.

Everyone could see the cat guarding the bottom of the ship.

Compared to human cats trying to overcome the psychological barriers, I don't know how much higher.

All the eyes of everyone looking at Xiao Tuanzi changed.

There is a faint sense of respect.

In addition to Xiao Tuanzi reaching this step, there are also a lot of people in her.

A minute, not that you can leave if you have enough, there may be an accident and you will be attacked by zombies.

If a few minutes of fighting is fine, but once it exceeds five minutes, then basically there is only death.

The only one who didn't go into the water was the S-class adept, and he listened to the discussion outside, and the look in his eyes was complicated.

He saw a lot of things in Xiao Tuanzi's body.

Gritted his teeth and closed his eyes, not snorting in pain.

The whole team was in that kind of full-scale training and no one complained about anything.

At the beginning, they were very angry about Xiao Tuanzi's decision, and they still had some complaints, but their strength was not as good as others, so they had to suffer, but until now they really have no complaints.

Time seems to pass quickly, and it seems to pass very slowly.

Misfortune will still happen, Xiao Tuanzi is killing a school of zombie fish here, and she has been surrounded by her.

Of course, many people next to him were also caught up in this battle.

There are many more people coming to the rescue.

The smell of blood wafted through the water, which meant that someone had been bitten.

The man felt a tearing pain in his body.

He was supposed to go up for a ventilation, but he wasn't going up.

The rest of the people didn't notice this because of the fight.

Slowly, he felt his body getting heavier and heavier, his hands and feet getting colder and colder, and the suffocating feeling coming from his head, as if he would die in the next moment.

Use the last of your strength to kill a zombie fish.

Xiao Tuanzi almost finished solving the group of zombie fish, and then he realized that something was wrong here.

The spiritual power was released, and all the zombies around it were emptied in an instant.

Grabbing a few people who were about to suffocate, he went straight back to the water.

Calculate the time, it's almost time now.

Three of them were bitten by zombies, and six were just a little suffocated.

Xiao Tuanzi turned out the serum in the space.

Three zombie type 11 serum, it still has it here.
