Zhang Qin led the fleet to sail at sea for several days, and the two stinky Taoist priests in the fleet competed to see whose position on the sea was accurate, so when they arrived at Chengshan and the sea, they did not dock for supplies, and relied on the ship to carry sufficient grain and water to sail directly to Danluo.

The three ships that Li Yu gave to Zhang Qin were the work of the craftsmen of the shipyard under the Yanwangfu for several years, and they were modeled after the best seagoing ships of the modern era.

The shipbuilding technology of the Tang Dynasty fully developed and further improved the effective use of the stern rudder, multi-layer ship plate, high-efficiency propulsion tool oar and sail that appeared in the Qin and Han dynasties, and also appeared advanced tenon and tenon nailing technology, which greatly improved the strength of the ship.

Li Yu's shipbuilders further refined these previous and contemporary shipbuilding techniques. The hulls of the three ships were cut down on both sides, and the keel was strung through the end and tail, with a ratio of about 10:1 between the surface and the bottom, and the bottom of the ship was V-shaped, which was convenient for sailing at sea. The shape of the bow was also changed to a pointed head.

The boat also uses watertight compartment technology, with a total of five watertight compartments per ship.

This technique only appeared in the early Tang Dynasty, and its application was not widespread. When Li Yu learned about it, he ordered the craftsmen to specialize in this new technology, and in more than three years, the shipbuilders of Yanwangfu became the most proficient in watertight compartment technology in the world today.

The process and technology of the watertight compartment greatly enhance the ship's ability to resist sinking, especially the lateral strength of the hull. It is a layer of watertight bulkhead enclosed by the bottom and two side ribs and a beam below deck. The bulkheads before the middle were installed before the ribs, and the bulkheads after the middle were mounted behind the ribs. This installation prevents the bulkhead from moving, so that the side of the ship is tightly bonded to the bulkhead panel, and the two sides are firmly supported, which enhances the lateral strength of the hull. Due to the increased sturdiness and sinking resistance of the ship, it is possible to have more masts and sails, which are more suitable for ocean navigation.

This is also the reason why Li Yu has the courage to explore overseas.

Without such advanced technology to build a sturdy ship, how would you sail on the oceans with strong winds and high waves?

In addition to the auxiliary stern rudder, the power of the boat mainly depends on the wind power of the sail with a combination of soft and hard sails. The two mainsails on the middle deck of the boat are still the traditional hard sails, but the bow and stern are made of the soft sails of later Western sails.

Given that the mainsail technology of later Western sailing ships was still too complex, the craftsmen never came into contact with it. From Li Yu's verbal description and drawing, the sketch can only be a general description, and does not involve the key technology of the sail.

The craftsmen listened to the clouds and fog, and when they looked at the picture, they could only see the shape of the soft sail raised, and they could only explore and experiment according to the sketch drawn by Li Yu, so that they have not yet fully mastered the technology of using soft sails in all boats.

The gray sky, where the sea and the sky meet in the east, the sun emits scorching sunlight and gradually illuminates the sea.

The young sailor in his early twenties sat at the bow of the ship yawning, the sun shining on his face, and his tired eyes opened to the sun. Suddenly, his eyes widened and he stared straight ahead, and he was surprised to turn to the other companions on deck and shouted, "Look, you have found land......"

"Who is howling there early in the morning, arguing that the Taoist master is sleeping, I don't know."

Wang Haichong rubbed his hazy sleepy eyes and ran out of his cabin, leaning on the railing and about to scold a group of sailors on the deck who didn't sleep early in the morning. Rubbing his clear eyes and looking down, the dozens of sailors on deck all shouted excitedly, and several even jumped up, and the sound came from the other two ships not far away.

"What are you doing stupidly? Dan Luo is almost here. ”

Wang Haichong's head was slapped directly from behind, and when he looked back, it was Uncle Sun Kang, an old man, who was hanging his stinky face that everyone owed him a hundred and eighty times, and ascended the stairs on the aft deck.

"Stinky old way." Wang Haichong muttered, and hurriedly followed to the deck to see what he understood.

As the head of the fleet, Zhang Qin had already boarded the stern deck, leaning on the right corner of the deck with the telescope handed over to him by King Yan before leaving, to observe the coastline in the distance.

Uncle Sun Kang, Wang Haichong and others, who ran onto the deck, looked at Zhang Qin holding the telescope with a look of envy.

Before leaving, Wang Haichong wanted to buy one by relying on the friendship between himself, the master and King Yan, but he didn't think that the price quoted by Li Yu would be expensive, but such a thing would cost a thousand yuan, so angry that he almost scolded Li Yu, and left in a frustrated manner.

In the end, I heard from the acquaintances in the Yanwang Mansion that this thing was priceless, and the craftsmen of the Yanwang Mansion did not make a few at all, except for the people in the Yanwang Mansion, few outsiders knew about the telescope.

Zhang Qin put down the binoculars and said, "Captain Yu, let the crew get ready, there are still seventy or eighty miles to arrive." ”

Yu Hong ordered the drummers to beat the war drums standing on the aft deck, and the drums struck twenty times in a row, followed by two other ships that followed behind the flagship and beat twenty drums in response.

The cheering crew on the deck rushed back to the cabin when they heard the drums, and under the orders of the officers, they quickly put on their armor and weapons from the weapons compartment and returned to the deck in an orderly manner.

"Captain Yu, how is the force of the Danluo Kingdom?" Uncle Sun Kang leaned against the edge of the boat and asked casually, and easily pulled out the long sword on his waist and played a sword flower.

Yu Hong chuckled: "Danluo." In the South China Sea south of Baekje. On Jushan Island. Zhou Hui and connected to the sea. A five-day trip north to Baekje. Its king's surname is Ru Li, his name is Duluo, and there is no city god. It was divided into five tribes, and its houses were round walls and covered with grass. There are 8,000 households, with bows and swords, and there is no record. Only ghosts and gods, permanent service belongs to Baekje. In the second year of Linde, Liu Renliang returned to the west of the sea with the envoys of Silla, Baekje, Tamna, and Wa, and would worship Mount Tai. ”

"This is played by the right minister Liu Renliang when he returned to Beijing after pacifying Baekje."

"There are only 8,000 households, 30,000 or 40,000 people in the sky, and there are probably only one or two thousand soldiers who can fight, and there are not even city gods." Shusun Kang held the sword and muttered with an expressionless face: "It's also divided into five parts, maybe we can beat Danluo down." ”

After Uncle Sun Kang finished speaking, Zhang Qin, Yu Hong and others were shocked, there were only more than 200 people in the fleet, and they wanted to destroy a country, is this joke too big? Although this country is small, it can also muster thousands of capable soldiers.

Wang Haichong pursed his lips disdainfully and said: "I said that you are an old Taoist fool, whether this island in front of you is Danluo has not yet been determined, and you are thinking about destroying a country." ”

"What? Little fat man, not confident in his bullshit compass sea positioning? Take advantage of the early kowtow to the poor road ten rings and pay ten times of money, and the poor road adults will not care about you if they have a large amount. ”

"Who do you say isn't confident?" Wang Haichong jumped to his feet and scolded: "We are seeking rigour, and we must make a conclusion after on-the-spot investigation. On a cloudy day, you'll just stare dryly, and rely on Lao Tzu. ”

"You little bunny......"

was exposed by Wang Haichong, and his uncle Sun Kang couldn't hold back his anger anymore and scolded and counterattacked, blowing his beard and glaring at Wang Haichong with a long sword.

Wang Haichong didn't show weakness, pulled out the long knife at his waist and scolded.

"Hey, doesn't Taoism pay attention to quiet and inaction? How can I not see a little bit from the two of them? Zhang Qin shook his head with a wry smile and said, these two living treasures will quarrel at both ends in three days.

Zhang Qin, Yu Hong and others hurriedly left the stern of the foul language in a depressed manner, and went to the bow of the ship to observe the outline of the island in the distance that was becoming clearer and clearer in the distance.
