Mr. Qu naturally had no objection.

So Yu Ren asked Liu Qiang to find two more carriages in the city, and also went to Liu Datou's iron shop and pulled a large bag of coal.

After the group drove out of Hangzhou City, they found an empty place more than ten miles outside the city. Yu Ren told everyone to move the hot air balloons out of the car and assemble them on the spot.

Soon, the hot air balloon was assembled.

Yu Ren personally added coal to the brazier and lit the firewood below to use as a fire.

Soon, the coal was burned, and several people pulled the hot air balloon as Yu Ren told him. A large amount of hot air was quickly poured into the hot air balloon. Slowly, the hot air balloon that was originally collapsed on the ground was slowly climbing up from the ground, like a leather bag filled with water.

This scene was long as Yu Ren expected, so he was not surprised. Huang Han and the others had seen the last experiment and were not surprised by the results of this time. Only Mr. Qu and Liu Qiang saw this scene for the first time, and couldn't help but be amazed at Yu Ren's shocking talent.

However, although the hot air balloons bulged, they never took off. At first, everyone thought that it might be that time had not come. However, seeing that nearly half of the bags of coal had burned away, the hot air balloons still did not react at all. Everyone couldn't help but feel a little anxious.

Sweat was also revealed on Yu Ren's forehead.

"Boss, what's going on?" Huang Han was also anxious.

Yu Ren approached the hot air balloon, and he gently lifted the bamboo basket below with his hand. With just lifting it lightly, the bamboo basket jumped as if it was about to fly. Everyone kept their breathing closed, fearing that their breathing would be heavy, so they blew down the hot air balloon that was about to fly.

However, the bamboo basket stopped moving after only a few jumps. Yu Ren lifted it gently and the bamboo basket jumped up again. However, after he let go, the bamboo basket fell to the spot and stopped moving after a few strokes.

"What's wrong? Could it be that my bamboo basket is not good?" Li Fu asked with some disconfidence. Seeing that Yu Ren always carried the bamboo basket, he thought the problem was on the bamboo basket.

"No. The bamboo basket is well made and the shelves are also well done. Your work has done a lot of colors. The problem lies in my design. I shouldn't have used such thick leather to make balloons. Although it is firm and not breathable, it is too heavy." Yu Ren quickly discovered the problem.

"What should I do?" several people asked at the same time.

Yu Ren pondered and said nothing. After a long time, he suddenly raised his head. "If you use cloth and apply oil paper on the outside, can it be guaranteed to be airtight?" Yu Ren asked Huang Han. Since Fatty Xu was not present, now, except for himself, only Huang Han is the most knowledgeable about this hot air balloon.

Huang Han thought for a while, "It should be OK! I'm afraid that the paper is not resistant to heat baking. I'm afraid it won't work after a long time."

Yu Ren knew that the time was urgent and he could not wait any longer. So he said to Liu Qiang, "You should go to the city with Huang Han immediately to customize a hot air balloon made of cloth, and buy more oil paper and paste back. As for the style and size, Huang Han knows it."

The two agreed and got on the carriage and left.

Yu Ren, who was standing there, did not wait. He racked his brains to come up with something that could fly people for more than two miles.

He drew a pattern similar to a glider on the ground. However, he quickly rejected the idea. Because he knew that even if he really made a glider, he would not be able to glide at sea. In the end, Yu Ren focused on making a big kite.

After all, there are no technical problems to be a big kite. It can be done quickly and can basically fly at sea. But in this way, the person who performs the mission needs very much courage and skills. This is an alternative plan he made when he cannot use the hot air balloon. Although this plan obviously poses great risks, there is no way. At present, he must come up with a way to send at least one person to Chenqian Island through the air.

Yu Ren and his team waited outside the city for about two or three hours before they saw the carriage Liu Qiang and Huang Han rushing back.

Since the cloth and paper were too soft and not firm, it took them a lot of effort to put them firmly on the hot air balloon rack.

By the time everyone is fully prepared, it is already dark.

However, everyone was eager to know whether this hot air balloon that they improved could fly into the sky. So Yu Ren once again added firewood and lit coal in the brazier.

After a while, the hot air balloon made of cloth and paper began to fill up again. Yu Ren climbed into the basket himself. Cao An also wanted to climb in and take a look. But Yu Ren stopped him.

"Don't come up now. I'll try it and fly. As long as it can fly, there's time for you to play in the future." Yu Ren said, adding another shovel of coal from the bag to the brazier. The flames in the brazier darkened, but soon became more intense.

Yu Ren raised his head and carefully observed the top of his head made of cloth and paper balloons. He knew that these were the key to his success or failure. Fortunately, everything was normal. Yu Ren felt the basket under him move for a moment, and he thought it was his illusion. But before he could squat down to check, the bamboo basket under him moved again.

"Ah! It's flying. It's flying." Cao An was the first to shout.

Everyone also discovered that the hot air balloon had indeed flew up. The big hot air balloon finally slowly rose up. Amid the cheers of everyone, the hot air balloon carried Yu Ren higher and higher, and finally flew over everyone's heads.

Yu Ren breathed a sigh of relief. Finally succeeded.

One day later, on the Daqushan Island outside Hangzhou Bay, Yu Ren was practicing landing on a large boat with fifty confidants carefully selected by Mr. Qu. In order to ensure that he could board Chenqian Island the fastest and safest, Yu Ren also designed a rope bridge with fishing nets as the bottom according to a rope bridge he saw in a tourist attraction in his later generations. What they are practicing now is how to use the boat to fix the rope bridge at the strongest end of the shallow stall and quickly pass the rope bridge.

Because Yu Ren thought about everything very carefully during designing it. This drill went very smoothly.

When the last pirate of the Li family who participated in the performance passed through the rope bridge, Yu Ren saw Mr. Qu, who had been standing on the shore, raised his hand to him.

Yu Ren ordered Liu Qiang to dock the ship.

When Yu Ren got ashore, he saw Li Yu and Ying'er standing beside Mr. Qu.

When Mr. Qu saw that Yu Ren had gotten ashore, he bowed to Li Yu. "Subsidiaries took them to the front and practiced a few more times to ensure that they would be foolproof when they landed on the island tonight."

Li Yu nodded, and Mr. Qu took the people away. Ying'er immediately made an excuse and left. On the coast, only Yu Ren and Li Yu were left.

Li Yu looked at Yu Ren. After a long time, he said, "How are you doing?"

Yu Ren smiled, which was his joy from the bottom of his heart. Because he heard from Li Yu's words that she cared for him. Now, Yu Ren no longer dared to have any extravagant expectations for Li Yu. After all, the identities of the two of them were too far apart, so far that even Yu Ren, a time traveler four hundred years later, did not know what method to use to eliminate it. Now, as long as he knew that Li Yu had him in his heart, he would be satisfied.

"It's pretty good!" Yu Ren looked at the few water birds passing by on the coast.

"I am as free as they are now, stopping as much as they want, and walk as they want, without sadness or concern."

Li Yu's expression dimmed. After a long time of silence, Li Yu then seemed to have made up his mind and said, "Actually, you should know a lot of things. I don't mean to hide them from you, but my identity is too special.

In fact, my real name is Li Ying. Li Yu is just a pseudonym for me. Our Li family has been doing overseas trade business since our ancestors. Later, when we arrived in the Jiajing Dynasty, the court suddenly stopped merchants from going out to sea. So our family began to carry out smuggling transportation like other maritime merchants.

In the middle and late Jiajing period, due to the attacks of Qi Jiguang and his uncle Yu Dayou, sea merchants like our family were forced out of the Ming Dynasty together with the Japanese pirates. My grandfather then moved to Luzon by boat with the Li family and many fellow villagers who had been engaged in maritime transportation for many years.
