"What about oxygen?"

"Simple, the soul candle of the West Sea can meet this need. Although it wasn't meant to do that, when ignited, it did supply oxygen. ”

A few blue candles appeared in the old hand's calloused hands, which Charles had seen once, and it seemed to be a medium used to summon the little black man with pieces of paper.

He really didn't expect that this thing could actually provide oxygen.

Walking around the boat, Charles nodded with satisfaction, worthy of being a top boat designer, what he didn't think about, the other party had already thought of it.

This level of renovation is no less than building a new ship, and these people actually did it in just one month.

"Yes, I like it very much, although I didn't say it before, but I will prepare for you the cost of renovating the boat. ”

Hearing this, the old man with the eyes showed a proud expression on his face, as a designer with ingenuity, he hoped that every ship he designed would be recognized by every employer.

But he quickly threw away this emotion, after all, he was still in a state of captivity.

The old man hesitated for a few seconds before asking, "Your Excellency, since the ship has been built, according to the agreement, it is time to let us go back, right?"

"Don't worry. And sea trials. Walking to the deck, Charles snapped his fingers below.

The crew who had been preparing next to him rushed up excitedly, ready for the sea trial.

With a low whistle from the narwhal. She began to sail towards the dark sea.

After a few hundred meters away from the ship, Charles patted his hand on the side of the ship. "Dude, change one for me to see. ”

"Click~" The gear machinery on the rear deck began to turn, and under everyone's gaze, the steel plates on both sides slowly gathered upwards like eggshells.

"Whoosh~" All the ropes on the deck shot out in all directions in an instant, and the handle that wrapped around the inside of the iron plate began to pull hard.

"Bump!" the two steel plates slammed together on top of them, making a muffled sound.

If someone looks from the outside, the narwhal at this time turns into a semi-elliptical iron ball.

There are no gaps left in this iron ball, and in front of the iron ball, there are a few small thick glass windows to facilitate the observation of the outside from the inside.

Although I can see, my vision is greatly limited, and I can only look straight ahead.

Since it is a sea trial, of course, it is to test the diving function of the boat.

The sailors, led by the designer, went to the cabin to open the water filling valve.

As the tank slowly fills with seawater, the whole ship slowly dives towards the water.

When the whole ship was fully submerged, everyone on board suddenly felt a tightness in their chests, and they instinctively increased their breathing, and the feeling was like the feeling of water brushing against their chests.

Sailor West's face was extremely ugly, and he had a hunch that this mission would not be as simple as the last time.

"Ok, no water leaks, everything is normal. Charles quickly rounded the boat and walked straight to the wheelhouse.

The furnishings in the cab have also undergone some changes, with a round, raised screen at the front of the steering wheel that looks like a very rudimentary TV.

"This is sonar, we found it with great difficulty, be careful with this thing, if this thing breaks, you are blind at the bottom of the sea. ”

After the old man finished speaking, he pressed a red button with his hand, and the screen lit up.

"Dut~" A small white circle slowly spread out from the middle of the screen. After a few seconds, it was another round of restarting.

Someone who had watched TV, Charles certainly understood what it meant, and it was similar to his sonic detection in bat form.

With this thing, anything that appears around the ship can be quickly reacted to on the screen. Both alive and dead.

"Dudu~" The sound of the sonar suddenly began to hurry, and the screen showed that there was a large group of bright spots, which were approaching the narwhal at the speed of the pole.

Everyone in the cockpit suddenly felt a sense of suffocation, and the eyes of the old man designer's hands trembled like a sieve, and he couldn't figure out how something came as soon as he opened it.

Before everyone could react, several large mouths with three rings of Sensen's fangs were directly printed on the glass of the observation port.

This scene frightened many people and screamed loudly.

Just as Charles was about to give the order to launch a torpedo, the hideous mouth on the glass disappeared, and several red streaks swung back and forth in front of him.

Charles glared at the second officer, Feuerbach, "Is it interesting?"

It's not an immediate danger, it's just this guy's shark.

Feuerbach smiled heartlessly, and he slapped his hand on the shoulder of the frightened and almost paralyzed old man. "Hahaha, Captain, I'm looking at everyone too nervous, so I'm just kidding everyone. ”

Charles turned his head to look at the bandage who was at the helm, "Take Hope Island as the center and circle around." Adapt everyone to work underwater. ”

Silent Bandage nodded and began to turn the rudder.

"As for you, since you're idle, come with me to work. Charles tugged at Feuerbach's collar and walked towards the captain's quarters.

There is certainly no difference between work on the water and work underwater, and as a captain, you must allocate the working hours of all the people to ensure that each of them has a reasonable amount of work and rest.

The underwater environment was even darker and more oppressive on the water, and the crew struggled to adapt, but there was one person on this boat who adapted quickly.

Lily leaned on the glass observation port in front of the deck, looking out in amazement, and the searchlight gave a panoramic view of the style of the sea.

Although it was dark for the most of the time, Lily still watched it with relish.

Just as she laughed as a blue-shelled nautilus was knocked away by a submarine, a large hand reached over and grabbed her, it was Charles's hand.

Putting her furry head on Charles's hand, Lily said happily, "Mr. Charles, I just saw a purple glowing thing, so pretty, so beautiful!"

"Don't look at it, it's still nothing on the island for the time being, if you go to the open sea, things outside can make you have nightmares. ”

"Oh, shall I look at it a little more now? I won't look at it when we go out to sea. ”

Charstowe walked her towards the cabin, "Take your rats to try out new weapons for underwater use, it's your gunner's duty." ”

Just as Charles raised his foot and was about to enter the hatch, he saw the bandages in the cockpit waving at him.

Charles just came to the cockpit, glanced at the chart next to him, and found that he hadn't driven too far, and it was more than forty nautical miles away from Hope Island.

"Yes...... Something found ...... "Bandaged hands pointing at sonar.

On the upper left side of the boat there is a bright spot that is twice as large as the ship, constantly shining.

"Is it moving?"

"I didn't ...... Looks...... Like a dead thing......"

"What is it when it's so close to the island? ”
