In the blink of an eye, many days passed.
White Stone Tower's wooden boat sailed down the Emerald River and docked in two relatively large cities for a few days. In the end, the number of people on board reached more than fifty.
After that, the wooden boat sailed to the estuary and entered the endless sea.
After driving on the sea for half a day, a dark shadow appeared on the sea.
When you get closer, 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 estimated that the displacement was at least several 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 or hundreds of tons.
In the Age of Discovery after the Middle Ages, shipbuilding technology developed rapidly, but the displacement was still difficult to reach 1,000 tons.
Until modern times, giant ships of several thousand tons were relatively common, while ships with tens of thousands of tons could only be reached by ocean-going cargo ships, large warships or aircraft carriers.
As he got closer and closer to the giant ship, Richard also saw more details, and finally his eyes fell on a certain part of the ship's hull close to the water. He raised his eyebrows and discovered something unusual.
It was a structure that was half submerged in the water, closely connected to the hull, but protruding forward significantly, like a big nose growing on the smooth hull.
This is the bulbous bow.
Richard thought in his mind.
This is something completely un-medieval.
If the volume and displacement of a ship can be forcibly piled up, the bulbous bow is different. It is completely a creation of technology.
When the hull travels on the sea, the resistance caused by waves that is opposite to the direction of the hull is called wave resistance. The energy of the ship's waves is supplied by the hull, and the existence of wave-making resistance consumes part of the power to propel the ship in a sense.
When a bulbous bow is installed, the waves generated by the bulbous bow will start from the wave trough, while the hull bow will start from the wave crest. After some adjustments, the trough of the bulbous wave system generated by the bulbous nose coincides exactly with the crest of the main hull wave system, and the effect of wave elimination can be achieved, reducing the resistance of the ship's navigation and reducing the propulsion power consumption by approximately 10%.
The 10% amplitude has no effect on ordinary voyages, but it is crucial on long-distance voyages, especially on long-distance voyages of giant ships with large displacements.
Even so, even though the bulbous bow plays an important role, the bulbous bow cannot be made if you want to. It is an extremely complex system that was only developed in the 20th century on modern earth and is mainly used on warships. Some data need to be calculated carefully, otherwise not only will it not be able to reduce resistance, but it may also increase resistance.
That is to say, this is a creation that transcends time and is here now.
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 aspects.
There seem to be more and more secrets in this world.
Richard thought as the wooden boat stopped next to 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 walked out of the cabin.
It's the wizard Sif.
During the many days on the boat, everyone had gotten to know this wizard who was not very talkative, and had also seen him use thunder to punish wrongdoers. As soon as you see Sif appear, get out of the way.
Sifu didn't say much. Without seeing any movement, he stepped on his feet and floated up onto the giant wheel. Everyone on the deck of the wooden boat exclaimed, almost all amazed at the magic of the spell and the power of the wizard.
Sifu boarded the giant ship, probably communicating with the people on the giant ship. In a moment, many figures appeared on the edge of the giant ship's deck, lowering the wooden ladder and letting everyone climb up.
After boarding the giant wheel, everyone truly realized how big the wheel was, and couldn't help but marvel. Even Grotto's eyes widened. Richard didn't react 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, moved her head little by little, and followed Richard step by step.
After that, it was time to divide the cabins. At this time, some levels finally showed their effect.
The ship was so big that the cabin below the deck was divided into three levels.
On the floor closest to the deck, only students with advanced wizard talents are eligible to live.
The second floor, slightly away from the deck, is where students with moderate talents live.
As for the third floor near the bottom of the ship, students with low talent or no talent who boarded the ship with an exemption certificate lived.
Going down to the third floor, you can clearly feel that it is low, cramped, damp and cold. The overall environment is completely dirty and messy. Moreover, you live with the sailors on the ship, which simply challenges the limits of many people's tolerance.
But that's all it can do, no one dares to disobey the wizard's orders.
Richard didn't mind this too much. For him, some living conditions can be kept to the simplest, and he can accept them as long as they do not affect normal activities.
To avoid being disturbed, Richard chose a cabin at the end of the third-floor corridor and walked in with Pandora.
After entering the cabin, she closed the door, put down her suitcase, and staggered to find a bed.
After finding it, I sat down on it and fell asleep.
But suddenly he raised his head again, opened his eyes, frowned, touched the bed and said to Richard: "Wet!"
Wet, very wet indeed.
Because the cabin is underwater, the air humidity is very high, and because the shipbuilding technology is not very high, water constantly seeps out of some gaps, making the entire cabin wet. The bulkhead is covered with moss, and there are even creatures such as snails and shells. A green-shell crab is crawling around in the corner.
The bedding was so wet that you could almost wring out the water. After just staying in this cabin for a while, you felt sticky on your body. This was because the air humidity was too high and the sweat could not be distributed normally. It was no wonder that the sleepy Pandora was not able to Can't sleep.
However, this is not a problem for Richard.
A simple spell does it.
The lips opened and closed slightly, free energy elements surged in the body, and the "water droplet condensation" spell was quickly released.
The moisture in the air quickly gathered towards Richard's fingertips, and then turned into drops of water. Under Richard's control, it fell into a wooden barrel in the cabin.
By the time the water in the 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 off one after another.
Pandora tentatively touched the quilt again, nodded with satisfaction, and then fell down to sleep.
Richard threw all the snails, shells, and green-shell crabs into the barrel. Just as he was about to breathe a sigh of relief, there was a knock on the cabin door.
"Bang bang!"
