"There is hope!" Tao Chengdao nodded heavily and had to admit, "Not only is there hope, but the possibility of success is very high. How did you grow this head?"

Han Du smiled and didn't answer. Didn't he look down on himself just now? He also deliberately turned his head to one side, disdainful to talk to himself. Now Han Du retaliated in kind, deliberately turning his head to one side and ignoring Tao Chengdao's questions.

Seeing that Han Du was getting angry with Tao Chengdao, Zhu Biao quickly intervened to smooth things over and said: "Wanhu, don't argue with him. He is just such a virtuous person. But he is indeed smart and can think about things that ordinary people don't think about and think about things that ordinary people don't think about."

Tao Chengdao smiled lightly and shook his head at Zhu Biao. How could he care about Han Du? It was too late for him to beg Han Du now.

"I don't know how many people I see putting up Kongming lanterns every year, but every year I see them in vain. I never thought about having anything to do with flying. Not only me, but those who have determined to fly to the sky for thousands of years are all smart.

, including me, the same is true. There are obvious examples right in front of you.

But he turned a blind eye." Tao Chengdao sighed more and more as he spoke, and in the end it turned into a long sigh. If Zhu Biao and Han Du weren't here, he really wanted to slap his old face.

He deeply doubted, how did he live in the past few decades? He couldn't even figure out such a simple thing.

Zhu Biao smiled awkwardly, comforted Tao Chengdao and himself, and said: "Wanhu said this too much, let alone Wanhu. Countless people have seen the Kongming Lanterns over the years, but who would be like this?"

Like Han Du, do you want to fly to the sky?"

Han Du was completely addicted and his vanity was satisfied, and then he slowly said: "This method is definitely possible, but it is not that simple to really make people fly."

"You tell me, I am all ears. As long as your method can fly, I will worship you as my teacher and do what you say." Tao Chengdao no longer had the arrogance he had just now, and instead behaved like a student with an open mind in front of Han Du.

Han Du waved his hands quickly and said, "Sir, you are serious. It was just a joke of mine. How could you take it seriously?"

"No, no, no, how can you be dishonest in your words? Don't worry, I will do what I say." Tao Chengdao was very stubborn and insisted on worshiping Han Du as his teacher.

Han Du shook his head when he saw it and said: "If the old gentleman insists on doing this, then I won't say anything. You can think about it yourself."

How could Han Du dare to ask Tao Chengdao to worship him as his disciple? Seeing that he was only a few years younger than Lao Zhu, and he was so valued by Lao Zhu, the relationship between the two might be close, even if they were of the same generation.

If Lao Zhu really had a friendship with Tao Chengdao, but he became Tao Chengdao's master, wouldn't this be taking advantage of Lao Zhu? If Lao Zhu found out, he might have his legs broken.

For the sake of his own legs, Han Du was determined not to let Tao Chengdao become his disciple.

Zhu Biao also knew that it was outrageous to have Han Du as his disciple at Tao Chengdao's age, so he intervened and persuaded Tao Chengdao to give up the idea.

Han Du then continued: "If you want to fly into the sky, you have to find a way to make the Kongming Lantern bigger. The bigger the lantern, the greater the power it generates. Naturally, it can carry more weight to fly into the sky. And other things, including people

Everything should be as light as possible inside.”

Tao Chengdao nodded repeatedly, indicating that he remembered.

Han Du continued: "More importantly, such a huge Kongming Lantern cannot be made of paper. The paper is too fragile and may not be able to bear the weight of a person."

Tao Chengdao nodded and agreed with Han Du's statement, but then asked quickly: "What should I use?"

"You can use cotton cloth, as long as it is woven densely and does not leak. However, cotton cloth is too heavy, so it is best to use silk. One layer of silk is too thin, so you can blend several layers of silk together." Han Du explained.

Tao Chengdao thought about cotton and silk silently in his mind. Since Han Du said silk was better, he immediately gave up cotton. Of course he would use the best. Anyway, he was not short of money. It was just a little silk. He developed this snake shape

I don’t know how much silk I can buy for the cost of a flying car.

"Also, using oil lamps is definitely not possible. In my estimation, if you want to make people fly, the Kongming lantern needed is probably several feet square. For such a large Kongming lantern, it is definitely not possible to use oil lamps."

"Then what should I use?" Tao Chengdao asked eagerly.

Han Du nodded and continued: "Use strong fire oil, and the oil-burning things must be specially made again."

"Okay, I've remembered it all." Tao Chengdao nodded, "I'll give it a try and see if it works. At that time, I'm afraid I'll need to ask the Marquis of Zhenhai for help and advice."

"Easy to say, easy to say." Han Du nodded.

Having said that, Han Du also put his mind on the roast lamb and continued to eat heartily.

Tao Chengdao's doubts were answered, and he was ready to eat. He picked up the mutton and ate it without any pretense. Even though Tao Chengdao was very old, he ate meat as fiercely as any young man.
