Magus Tech Chapter 151: It’s wet

In the blink of an eye, many days have passed. . For more latest chapters visit: ШЩЩ.⑦⑨XS.сОМ.

The wooden boat of Baishi Tower went down the Emerald River, stopping at two relatively large cities for a few days on the way, and finally the number of people on board reached more than 50 people.

After that, the wooden boat sailed to the mouth of the sea and entered the endless sea.

After driving on the sea for half a day, a black shadow appeared on the sea.

When you get close, you can see that it is a huge ship.

If a wooden boat is like a hill, then a giant ship is like an island. Richard estimates that the displacement is at least a few thousand tons.

This is an exaggerated level.

The larger the ship, the more difficult it is to make. In fact, the shipbuilding technology in the Middle Ages was not developed, and most of them were sea-going ships with a displacement of tens to hundreds of tons.

In the era of great navigation after the Middle Ages, shipbuilding technology made rapid progress, but the displacement was still difficult to reach a thousand tons.

Until modern times, giant ships of several thousand tons were relatively common, while those of tens of thousands of tons could only be achieved by ocean-going freighters, large warships or aircraft carriers.

As the ship got closer and closer, Li Cha also saw more details, and finally his eyes fell on a certain part of the hull close to the water surface. She raised her eyebrows and found something unusual.

It is a structure that is half submerged underwater, closely connected with the hull, but protruding forward substantially, like a big nose growing out of the smooth hull.

This is the bulbous bow.

Li Cha thought in his heart.

This is something that does not belong to the Middle Ages at all.

If the volume and displacement of the ship can be forcibly piled up, but the bulbous bow is different, this is completely a creation of technology.

When the hull is running on the sea surface, the resistance caused by "waves" and "waves" opposite to the forward direction of the hull is called "wave-inducing" resistance. The energy of the ship's "wave" ups and downs is supplied by the hull, and the existence of "wave" resistance consumes a part of the power to propel the ship in a sense.

With the bulbous bow installed, the 'wave' generated by the bulbous bow will start from the 'wave' trough, while the hull bow 'wave' will start from the 'wave' crest. After some adjustments, let the "wave" trough of the spherical bow "wave" system generated by the bulbous nose coincide with the "wave" peak of the main hull's "wave" system, and the effect of "wave elimination" can be achieved, reducing the ship's Sailing resistance reduces propulsion power consumption by approximately 10%.

The range of 10% will not be effective in general voyages, but it is very important in long-distance voyages, especially long-distance voyages of large ships with large displacement.

Even so, even though the bulbous bow plays an important role, the bulbous bow is not something that can be manufactured just by thinking about it. . Some data must be calculated precisely, otherwise not only will the effect of reducing resistance not be achieved, but it may also increase resistance.

That is to say, this is completely a creation beyond the times, and it is now appearing in front of you.

It seems that due to the influence of wizards or other factors, although the current world is similar to the Middle Ages, it is not exactly the same. Some things have changed, including the level of technology in certain areas.

There seem to be more and more secrets in this world.

Li Cha was thinking, and the wooden boat stopped beside the giant ship.

Everyone was standing on the deck, looking up at the tall ship, suddenly there was a sound of footsteps, and a person stepped out of the cabin.

It's Sif the wizard.

During the many days on the boat, everyone had gotten to know this not-so-talkative wizard, and had seen him use thunder to punish those who made mistakes. As soon as he saw Sev appearing, he immediately moved out of the way.

Sev didn't say much, didn't see any movement, stepped on his foot, and the whole person floated up and floated on the giant ship. Everyone on the deck of the wooden boat exclaimed, almost all marveling at the magic of the spell and the power of the wizard.

Sev boarded the giant ship, and he was supposed to be 'communicating' with the people on the giant ship. After a while, many figures appeared on the edge of the giant ship's deck, lowered the wooden ladder, and let everyone climb up.

After boarding the giant wheel, everyone truly realized the size of the giant wheel, and couldn't help being amazed again, even Gro's eyes widened. Li Cha didn't react too much. After all, there are bigger ships on the modern earth. As for Pandora, she didn't even open her eyes. She closed her eyes, nodded her head, and followed Li Cha step by step.

Afterwards, the cabin is divided. At this time, some levels finally showed their effect.

The giant ship is very big, so the cabin below the deck is divided into three floors.

On the floor closest to the deck, only students with advanced wizard talents are eligible to live.

The second floor, a little farther away from the deck, is where students with medium talent live.

As for the third floor near the bottom of the ship, it is for students with low talents or no talents who board the ship with the certificate of exemption from examination.

When you go down to the third floor, you can clearly feel the low, cramped, damp and cold conditions here. Sailors live together, simply challenging the limits of many people's endurance.

However, this is the only way to go. Facing the wizard's order, no one dares to disobey.

Li Cha didn't mind much about it. For him, some living conditions can be kept as simple as possible, as long as it does not affect normal activities.

In consideration of avoiding being disturbed, Li Cha chose a cabin at the end of the corridor on the third floor, and walked in with Pandora.

After entering the cabin, Pandora closed the 'door', put down the suitcase, and staggered to find the 'bed' automatically.

After finding it, I sat up on it and fell asleep.

But suddenly raised his head again, opened his eyes, frowned, 'touched' the 'bed' and said to Li Cha: "Wet!"

Wet, really wet.

Because the cabin is underwater, the air humidity is very high, and because the shipbuilding process is not very high, water seeps out from some gaps, making the entire cabin wet. The bulkhead is covered with moss, and there are even creatures like snails and shells, and a green-shell crab is crawling around in the corner.

The quilt is so wet that water can be wrung out. After staying in this cabin for a while, I feel sticky on my body~IndoMTL.com~It is because the air humidity is too high and the sweat cannot be released normally. No wonder the sleepy Pandora couldn't sleep.

However, this will not trouble Li Cha.

A simple spell does the trick.

The mouth'lips' opened and closed slightly, the free energy elements in the body surged, and the "water droplet condensation" spell was released quickly.

The moisture in the air quickly gathered towards Li Cha's fingertips, and then turned into drops of water, which fell into a wooden barrel in the cabin under Li Cha's control.

By the time the water in the wooden barrel was almost full, the cabin had become extremely dry, as if it had been exposed to the sun. The moss turned from emerald green to withered yellow, and the snails and shells attached to the bulkhead fell down one after another.

Pandora tentatively 'touched' the bedding again, nodded in satisfaction, then fell down and fell asleep.

Li Cha threw all the snails, shells, and blue-shell crabs into the barrel, and was about to breathe a sigh of relief when there was a knock on the cabin door.

"Boom!"
