Mr. Qu naturally has no opinion.

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

When the group drove out of Hangzhou City, they found an open place more than ten miles outside the city. Yu Ren instructed everyone to move the hot air balloon out of the car and assemble it on the spot.

Soon, the balloon was assembled.

Yu Ren personally added coal to the brazier and then lit the firewood underneath to start the fire.

Soon, the coal was burned, and several people pulled up the hot air balloon according to Yu Ren's instructions. The hot air balloon was quickly filled with a large amount of hot gas. Slowly, I saw that the hot air balloon that had collapsed on the ground was slowly climbing up from the ground. It's like a leather bag filled with water.

This scene had long been expected by Yu Ren, so he was not surprised. Huang Han: Because they had seen the last test, they were not too surprised by the results this time. Only Mr. Qu and Liu Qiang saw such a scene for the first time, and they couldn't help but marvel at Yu Ren's earth-shattering talent.

However, although the hot air balloon was inflated, it never took off. At first, it was thought that the time might not have come. However, seeing that nearly half of the bag of coal had been burned, the hot air balloon still did not react at all. Everyone couldn't help but be a little anxious.

Yu Ren's forehead also showed sweat.

"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 such a slight lift, the bamboo basket jumped with it, as if it was about to fly. Everyone held their breath for fear that their breathing would be heavy, and they blew down the hot air balloon that was about to fly.

However, the bamboo basket only jumped a few times and then stopped moving. Yu Ren lifted it lightly again, and the bamboo basket jumped up again. However, as soon as he let go, after a few strokes, the bamboo basket fell back to the same place and did not move.

"What's wrong? Could it be that my bamboo basket can't be made? Li Fu asked a little unconfidently, he saw that Yu Ren always carried the bamboo basket, so he thought that the problem was on the bamboo basket.

"Nope. The bamboo basket is very well done, and the shelves are also very well done. Your work is very colorful. The problem is with my design. I shouldn't have made balloons out of such thick skin. It's sturdy and not breathable, but it's too heavy. Yu Ren quickly discovered the problem.

"What then?" Several people asked at the same time.

Yu Ren was silent in thought. It was a long time before he suddenly raised his head. "If you use cloth and put oiled paper on the outside, can you ensure that it is not breathable?" Yu Ren's words were directed at Huang Han. Since Xu Fatzi was not present, now here, except for himself, only Huang Han is the most knowledgeable about this hot air balloon.

Huang Han thought for a moment, "It should be possible!" I'm afraid that the paper is not resistant to hot fire. I'm afraid it won't work for a long time. ”

Yu Ren knew that time was urgent, and he couldn't wait any longer. So he said to Liu Qiang, "You go into the city with Huang Han immediately, go and 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 said yes and got into the carriage and left.

Yu Ren, who was staying in place, did not have time to wait. He racked his brains to come up with something that could carry people more than two miles.

He drew a glider-like pattern on the ground. However, the idea was soon rejected. Because he knew that even if he really made a glider, there was no way to glide at sea. In the end, Yu Ren focused on making a big kite.

After all, there is no technical difficulty in making a big kite, it is fast to do, and it can basically fly at sea. It's just that in this way, the person who performs the task needs to be very brave and skillful. This is an alternative he does when he can't use a hot air balloon. Although there are also obvious risks associated with this option. However, there is no other way. Right now, he had to come up with a way to send at least one person to Chenqian Island by air.

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

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

By the time everyone was completely done, it was already dark.

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

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

"Now don't come up yet. When I try it, it can fly. As long as you can fly, there will be time for you to play in the future. As he spoke, Yu Ren added another shovel of coals from the bag to the brazier. The flames in the brazier dimmed, but soon they burned even brighter.

Yu Ren raised his head and carefully observed the top of the balloon made of cloth and paper above his head. He knew that these were the keys to his success or failure. Luckily, everything is working fine. Yu Ren felt the basket under him move, and he thought it was his own delusion. But before he could squat down to check, the bamboo basket under him moved again.

"Ahh Flew up. Flew up. Cao An was the first to shout.

At this time, everyone also found out that the hot air balloon really flew up. The big hot air balloon finally slowly went up. In 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 it worked.

A day later, on Daqushan Island outside Hangzhou Bay, Yu Renzheng took 50 of Mr. Qu's carefully selected cronies to practice landing on a large boat. In order to ensure the fastest and safest landing on Chenqian Island, Yu Ren also designed a rope bridge with fishing nets as the bottom according to a rope bridge he later saw at a tourist attraction. They are now practicing how to use the boat to fasten the end of the rope bridge at the shallow stall and quickly cross the rope bridge.

Because everything is in the design, Yu Ren has thought about it very carefully. The drill went very smoothly.

When the last Li pirate to participate in the performance crossed the rope bridge, Yu Ren saw Mr. Qu, who had been standing on the shore, raise his hand to him.

Yu Ren ordered Liu Qiang to dock the ship.

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

When Mr. Qu saw Yu Ren coming ashore, he bowed his hand to Li Yuyi. "The subordinates took them to the front to practice a few more times to ensure that tonight's landing on the island was foolproof."

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

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

Yu Ren showed a smile, which was his joy from the bottom of his heart. Because from Li Yu's words, he heard her concern for himself. Now, Yu Ren no longer dares to have any extravagant hopes for Li Yu. After all, the identities of the two of them are too far apart, so far away that even Yu Ren, a time-traveler four hundred years later, doesn't know what method to use to eliminate it. Now, as long as he knew that Li Yu still had him in his heart, he would be satisfied.

"That's good!" Yu Ren looked at a few waterfowl passing by the shore.

"I'm as free as them now, I can stop when I want, I can go when I want, without sadness or concern."

Li Yu's expression darkened. After being silent for a long time, Li Yu seemed to have made up his mind and said, "Actually, you should know a lot of things." I didn't mean to hide it from you, but my identity is too special.

Actually, my real name is Li Ying. Li Yu is just a pseudonym for me. Our Li family has been in the business of overseas trade since our ancestors. Later, in the Jiajing Dynasty, the imperial court suddenly did not allow merchants to go to sea. So, our family followed the other maritime merchants and began to smuggle them.

In the middle and late Jiajing period, due to the blows of Qi Jiguang and General Yu Dayou, Ling's uncle. Maritime merchants like our family were forced out of the Ming Dynasty together with the Japanese Invaders. So my grandfather took the Li family and many other villagers who had been engaged in maritime transportation for many years, and moved to Luzon by boat.
