Liang Xiao grinned, leaned into Liu Ling's ear, and whispered: "Master Weng, your subordinates are watching."

"Oh." Liu Ling was stunned for a moment, slowly pushed Liang Xiao away, looked around, with a majestic and solemn expression.

The Huainan Langguan around him immediately felt a strong murderous intent, and turned his face to the same time, and focused on his work. Even the thunder quilt cough coughed, pressed the sword, took square steps, patted the Langguan's shoulders from time to time.

"Be careful, don't be careless."

"Here." The Langguan also replied seriously, his voice loud and his expression focused.

As for Wei Qing, he lay on the side of the boat, and seemed to have not moved from beginning to end.

"Look, they didn't see anything." Liu Ling turned around, opened his arms, and showed a smug smile on his face. At this moment, she was no longer the tall Huainan master, but just a child's head with countless friends.

Liang Xiao stroked his forehead. Liu Ling has a tendency to become childish recently. He often acts habitually and acts cute. Apart from the brocade clothes on his body, it is no different from ordinary women.

"Tell me quickly." Liu Ling pulled Liang Xiao's arm and dragged him into the cabin. "I have been thinking about it for two days, but I haven't figured out why you wanted to tear my boat. Why?"

Liang Xiao thought about it carefully, until Liu Ling pouted and was about to get angry again, he said, "Master Weng, in the swimming pool, no, do you feel any difference when there is water and no water in the soup pool?"

Liu Ling blinked, not understanding.

"When there was no water in the pond, did you notice that the boat was different from before?"

Liu Ling became even more confused. She was annoyed, and she bowed, stretched out her two fingers and said angrily: "Do you say or not? If you don't say it, I'll pinch you."

Liang Xiao's cheeks were twitched, and he didn't dare to keep it in hiding, so he had to honestly explain the principle of the center of gravity.

The tower ships of this era can be used as warships, but they are usually used as command ships of the main general and do not participate in battles directly. In order to show the majesty of the main general, the tower ship will be made very high. In this way, there is a serious problem: the center of gravity of the tower ship is too high and cannot resist the wind.

The largest shipyard in Dahan is in Yuzhang. Yuzhang is already in the middle reaches of the Yangtze River, and the wind and waves are not small. However, both frequency and intensity are much weaker than those on the sea. Even so, when sailing in the Yangtze River, the tower ship will drive when the wind is low. Once the wind is too strong, they will choose to enter the port to shelter the wind.

Liang Xiao wanted to dig a large pond on the building boat and poured it with seven feet deep water. The water is dozens of tons, which will seriously increase the center of gravity of the building boat. Once there is wind, it will easily cause overturning. In order to reduce this danger, Liang Xiao not only needs to dig the pond on the bottom floor and close to the deck, but also have to demolish all the floors on the upper floor to reduce the center of gravity as much as possible.

Liu Ling finished listening patiently and woke up from his dream. "Do you still know how to build a ship?"

Liang Xiao shook his head quickly. "I don't know how to build a ship, this is just basic common sense..." Before he finished speaking, he realized that he had said the wrong thing again. Liu Ling's eyes were a little bad, like an angry female lion. He quickly changed the topic. "Master Weng, if you want to travel abroad, there are still several problems to solve, so that you can run around the world and lead the world alone."

"Say." Liu Ling clenched his fists and waved them twice, but his eyes could not hide his smile.

"First, the boat should further lower its center of gravity. If you have the opportunity, you should examine and consider the sea boat. The boats traveling in the sea are different from those in rivers. Second, you must learn to use the wind, which is what I am about to say to you. Third, you must learn to use the stars to locate. When you get to the vast sea, there is water all around you. You can only rely on the stars to locate..."

Liu Ling interrupted, "Are you talking about Xingzhe?"

"Astrology?"

"I have heard of the astrology in the sea, which means positioning according to the stars when sailing on the sea."

"Is there such a thing?" Liang Xiao was a little confused. Was the navigation technology of the Han Dynasty so awesome?

"I only heard of its name, and have not been detailed in detail. Yes and no, and it still needs to be verified. However, when Xiaowen was banned, the switch was banned, and business traveled all over the world. There were many overseas merchants entering and leaving the Central Plains. They should have come from the sea, and it is not impossible to position according to the stars. Let's put this aside, let's talk about it, what's going on with the wind?"

Liang Xiao calmed down his mood. "Did Lord Weng almost be taken away by my clothes just now?"

Liu Ling raised his eyebrows slightly and suddenly realized. "You mean, do you want to take a ride like some cloth bags and take advantage of the wind to sail?"

Liang Xiao quickly flattered. "The Master Weng is wise."

"And!" Liu Ling smiled. Her eyes rolled and said, "How did you come up with this idea?"

"I just..."

"Okay, okay, when you don't drink, you don't have a few truths. Let's talk about how to make a cloth bag."

Liang Xiao was speechless. He had to put aside the right and wrong and talk about sailing on the boat first. There was no big wood that could make masts on the boat, so they could only put it in first, and used brocade and silk to make some small sails in the cabin, and hung them on the side of the boat. Although the effect was not as good as the sail, the poles were also visible, and the speed of the boat suddenly increased a lot. When the wind was strong, there was no need to paddle by sailors at all, and the boat could travel by the wind.

Looking at the bow of the boat and the full sails on the side of the boat, Liu Ling was so happy that even the officials of Huainan Kingdom were amazed, and the eyes looked at Liang Xiao were a little strange. Everyone knew that the wind was strong, and anyone might have been unable to stand by the wind, but Liang Xiao was the first person who could think of this method.

Thinking of the previous saddle, stirrup, and Liang Xiao had become a craftsman who was good at thinking and very talented in the mouths of the men.

Liang Xiao was worthy of it. As far as he knew, even without his participation, the Han people would soon invent sails. This thing is not complicated. Someone may have used it, but it has not been taken seriously. Only when maritime trade becomes large and more people use it will enter the vision of the historian.

By the way, "Records of the Grand Historian" has not appeared these days. All historical records are official archives, and there is no formal history of dynasty, let alone general history. Even historical books are just clauses like "Spring and Autumn" that record major political events, and will not record the invention of sail.

As far as he knows, the final evidence that there was sail in the Han Dynasty was not from historical books, but from the Ming utensils buried in the tomb.

Confucianism is the only one... When Liang Xiao thought of this, he couldn't help but sigh.

With the help of dozens of small sails, the speed of the tower ship was greatly increased, but the oarsmen became much more relaxed. The soldiers who supported the rudder quickly adapted to how to cooperate with the sails and control the direction. The working people are smart, but they have no culture and cannot write down their unique insights and leave them to future generations.

Seeing Jinfan bulging the wind and pushing the boat through the waves, Liu Ling stood on the Feilu, which was only one floor left, thinking about something.

Two days later, Liang Xiao and others arrived at the sea outside Dongye, which is the mouth of the Minjiang River. In fact, with the help of wind, the speed was at least two or three times faster than purely using manpower, and the labor intensity of the paddlers was also significantly reduced.

Liu Ling invited Liang Xiao and Wei Qing to the cabin. "Dongye is coming, what plans can you plan?"

Liang Xiao and Wei Qing looked at each other and shook their heads. Liang Xiao said, "I don't have any plans, just go to my master to see what he means, if..."

Liu Ling interrupted Liang Xiao. "If he is willing to accept the pleading, everyone will be happy. If he does not accept the pleading, will you find a way to escape?"

Liang Xiao nodded awkwardly. He did think so. When he arrived at the capital of Minyue, he was not familiar with the place. If he didn't do this, what else could he do?

“I have a suggestion.”

Liang Xiao was overjoyed. To be honest, he had a foresight about the overall situation and could not be compared with Liu Ling, but he was a little far from comparing his ability to handle such specific matters. If Liu Ling was willing to give him an idea, the probability of success of this matter would inevitably increase greatly. He stared at Liu Ling for a long time without blinking, but Liu Ling did not speak. Liang Xiao became a little uneasy.

"Master?"

"I'm going with you."

"No!" Liang Xiao refused immediately without thinking. "If you are in danger, Wei Qing and I still have a chance to escape. It would be not that easy to bring you with you. You bumped into many Minyue warships at the mouth of Songjiang River and captured Zhengwu and Jingzhao alive. Whether it is the King of Minyue or Liu Ju, you will be very angry when you see you. Maybe you will be arrested and taken as a hostage when you see you."

"It is precisely because I captured Zhengwu and Jing Zhao alive that this matter is something to be discussed." Liu Ling smiled confidently and said, "Can you take me there?"

Liang Xiao was speechless and had to look at Lei Que. Lei Que with a bitter smile and sighed. It seemed that Liu Ling had already explained to him, and he could only stand on Liu Ling's side now.

"Since Lord Weng decided to go, we have to sacrifice our lives to accompany the gentleman. Lord Weng, can you tell us your plan now?"

"Let's talk about it when you enter the city." Liu Ling waved his hand, like a general who commanded thousands of troops.

The boat entered the port, found a relatively remote location to stop, went to the flag of Huainan Kingdom, put down several small boats, loaded the goods, went ashore to trade, replenish supplies and Danshui. Liu Ling got on a carriage, and Lei was taken with two attendants, and Liang Xiao and Wei Qing entered the city separately.

After meeting, Liu Ling ordered: "Go to the Conquest Mansion."

Liang Xiao was shocked. If you captured Zhengwu alive, you dare to go to Zhengfu? It’s okay to say that Zhengban is the only one who did not shoot you to death.

"If you don't enter the tiger's den, how can you get a tiger's son?" Liu Ling smiled relaxedly and said: "It's best for women to communicate with women. I'll deal with you as a junior sister first, so other things will be easier. Let's go, don't talk too much. I've listened to you all the way, and now I'll let you see my skills."

Liang Xiao had no choice but to put away the documents, put on his ordinary knight's uniform, and protected Liu Ling to the Zheng Mansion--
