Although Han Du no longer has a title, not many people are qualified to instruct Han Du in such a condescending manner. But Qia Qia Tao Chengdao is qualified to instruct Han Du.
Han Du followed his servant to Wanhu Mansion and was brought to Tao Chengdao. Suddenly seeing Tao Chengdao, Han Du was startled by his appearance.
I saw that Tao Chengdao had lost a lot of weight, and he was sitting on the chair, as if he were just a few clothes casually draped on the chair.
"Wanhu, what's wrong with you?"
Tao Chengdao was taking a nap just now, and he suddenly woke up when he heard Han Du's voice. Seeing Han Du's face blooming with a smile, and seeing him looking at him with worry, Tao Chengdao glanced at himself a few times, and asked doubtfully
Said: "What's wrong, old man?"
"What's wrong with Wanhu?" Han Du asked uncertainly, thinking that Tao Chengdao was sick.
When Tao Chengdao saw Han Du coming, a smile suddenly appeared on his face. Seeing Han Du's concern for him, Tao Chengdao felt warm in his heart. He said with a smile: "It doesn't matter, I'm just old, so I can't stand
It's been too long and my legs and feet can't bear it. You can't let me stand waiting for you, right?"
"No, no, no, how dare I." Seeing that Tao Chengdao was fine, Han Du immediately smiled and waved his hands.
Tao Chengdao struggled to hold up the armrests with both hands, trying to stand up.
Han Du saw it and quickly reached out to help him.
After Tao Chengdao stood up, he looked at Han Du with a smile and sighed: "This man really can't bear to accept me. Originally, I was still angry that you went to ride a hot air balloon without me. But now I'm like this,
It’s hard to even stand up, but I know I shouldn’t blame you.”
"Wanhu, aren't you?" Han Du looked panicked.
At Tao Chengdao's age, if he were to fly into the sky again, Han Du would suspect that he would only be able to stand up and come down sideways. Fortunately, Tao Chengdao gave up on his own, so no further trouble occurred.
"Wanhu doesn't know, but what I'm doing this time is a hot air balloon show. The hot air balloons are tied by ropes and can't fly very high, only a few feet high." Han Du patiently explained to Tao Chengdao, "Wanhu
I have already flown to the clouds to see it, so why should I care about the height of a few feet?"
"Is that so?" Tao Chengdao looked confused. When he heard that Han Du got on the hot air balloon, he thought Han Du had flown into the sky again. He didn't expect that people outside had no knowledge and just saw the hot air balloon.
When the balloon flew up, it was filled with praise and praise.
Han Du laughed and said, "Of course it is. Think about it, this performance is for the common people. If it flies too high, the common people can still see it."
What?"
"That's it," Tao Chengdao nodded, and then put down his thoughts. For someone like him who has flown above the clouds, flying only a few feet high is just out of reach for him and completely makes him unable to mention it.
Get interested.
"Come here." Tao Chengdao shouted towards the door.
Tao Chengdao's two apprentices walked in quickly and helped him up.
He turned to Han Du and said, "I didn't come to you today just for the hot air balloon ride."
"If anything happens to Wanhu, just give me the order." Han Du quickly replied. Whether Tao Chengdao's words were true or false, Han Du didn't bother to tell. Anyway, as long as Tao Chengdao didn't want to fly, everyone else and Han Du would try to follow him.
Tao Chengdao sighed and said, "It's not about the fire dragon coming out of the water."
As he said that, he raised his eyes and glanced at Han Du, complaining: "You have been back for so long and you haven't even come to see me. Even if I don't show favor to you, what about Fire Dragon Izuku? You've also thrown it aside?"
Facing Tao Chengdao's complaining eyes, Han Du could only respond with embarrassment. He could only follow his words and ask: "What happened to the fire dragon coming out of the water?"
As expected, Tao Chengdao was attracted by Han Du's words and sighed, "You'll know when you go and take a look."
Han Du followed Tao Chengdao to the backyard and looked at several fire dragons placed on wooden shelves. The appearance of this thing was very different from the first one. Not only did the appearance look three to four points familiar to Han Du, but the whole body
The cylindrical front end also has a conical tip, and the tail is also equipped with two fins, and the surface is also painted with a layer of red paint.
"Why is it painted with red paint?" Han Du reached out and touched it, and found that the paint surface was smooth and not sticky at all.
Tao Chengdao stepped forward and explained: "This thing is an iron shell after all. If it is not treated, it will often rust. And if you use oil to prevent rust, it can only prevent it for a short time. Fortunately, the iron shell
The skin is rough and the flesh is thick, so I simply painted it with a layer of red paint. As for why red paint was used, of course red paint is cheap."
Han Du knew that Tao Chengdao had misunderstood what he meant. What he wanted to say was that the red color did not match his impression, but he understood that red paint was cheaper.
However, Han Du didn't say anything else. He couldn't force him to paint the fire dragon green, right? The name was Fire Dragon, and the red paint was truly worthy of the name and complemented each other.
If it must be painted green, wouldn't it mean that the old cucumber should be painted green?
Han Du looked at the decent-looking fire dragon, touched his chin and asked, "It looks good, what's the problem?"
Tao Chengdao reached out and stroked the fire dragon, he was even more careful than touching the girl's skin.
After a moment, he looked back at Han Du and sighed: "Your suggestion was very good last time. The problem of flying around was actually solved after pretending to have so many arrow feathers under your suggestion. Now it's solved
As long as it flies out, it will fly out as straight as a line and will not roll randomly. However, it still has problems."
"What's the problem?" Han Du then asked.
Tao Chengdao continued to explain: "This thing is indeed very powerful, but there is a problem. That is, it sometimes explodes in the sky, and sometimes it falls into the soil before exploding. Do you have any way to solve this problem?
Did it explode as soon as it hit the ground?"
Han Du immediately understood what Tao Chengdao meant, but regarding this thing, although Han Du knew what was going on, it just didn't have a firing device. But Han Du himself didn't know how to make this thing, he just knew that it should be like this
Only a device can make the fire dragon explode the moment it touches the ground.
After thinking for a moment, Han Du took out a bullet from his waist and handed it to Tao Chengdao, "Does Wanhu know this?"
Tao Chengdao nodded.
Han Du continued: "You see, this thing is perfectly fine when it is left on normal days, but as long as something hits it violently, it will be ignited and explode instantly. I'm wondering, should this fire dragon be the same?
"
Tao Chengdao stretched out his hand in confusion, took the bullet from Han Du's hand, and looked at it in confusion. Both the bullet and the revolver were invented by Han Du, which was a big deal for Tao Chengdao, who had always been the first master of Ming Dynasty firearms.
It was a big blow. Although Tao Chengdao did not deliberately embarrass Han Du, he still had a grudge against it in his heart. It was precisely because of this that he had always subconsciously ignored the bullets and revolvers invented by Han Du.
After a while, Tao Chengdao nodded slowly and sighed: "What a good idea."
Then he pointed at the fire dragon and said, "Actually, isn't this fire dragon just a bigger bullet?"
Han Du laughed, shook his head and said: "This is completely different, but the ignition and explosion should be similar. As for how to do it, I don't know. We still need Wanhu to find a way."
Tao Chengdao nodded, "We have a solution.
That’s easy to handle, the rest is just a matter of trying them one by one, this old man is good at it. However, I would like to thank you again this time.”
The reason why he thanked Han Du was because Tao Chengdao thought that since Han Du had thought of this, there might be a way to solve this problem. But Han Du deliberately didn't say it now because he wanted to leave the opportunity to
he.
Tao Chengdao has been studying firearms all his life, but when he began to study fire dragons, he was deeply fascinated by them. If he could make fire dragons, it would be easy to be famous in history. You know, there are countless people in this world who work hard.
I have spent my whole life, but I can't even leave a single word in the history books.
So Tao Chengdao vowed that he would create the fire dragon even if it cost him his life.
At the same time, he was also very grateful to Han Du who deliberately gave him this opportunity.
"There is another question." Tao Chengdao continued.
Han Du smiled and nodded, "Wanhu, please tell me."
"I tried several times and found that this thing didn't fly far, about four miles." Tao Chengdao was obviously very troubled by this problem, and his face was full of frustration when he spoke.
Han Du also felt something was wrong. How could it be only four miles away? You know, in the past, Tao Chengdao's fire dragon out of water could fly two or three miles away.
Of course, the fire dragon is made of paper and is naturally much lighter in weight. However, although this fire dragon is heavier, it also contains more gunpowder. Logically speaking, it can't fly more than four miles.
Just far away.
"Is there too little gunpowder?" This was the answer that Han Du could think of in an instant.
Tao Chengdao was also undecided as to whether this was the problem. He just tentatively said: "I don't know, but I started to wonder if there was too little gunpowder, but I asked people to put as much gunpowder as possible, and even used
The wooden pestle compresses the gunpowder tightly, and the result is similar."
What was going on? Han Du couldn't figure it out for a while, so he simply said: "How about you open one and let me see it?"
Tao Chengdao nodded, immediately waved his hand and pointed at a fire dragon and said: "Open it!"
Several apprentices came over, lifted a fire dragon off the wooden frame, and placed it on the long table. Then several people took wooden knives and opened the tail of the fire dragon bit by bit.
After opening it quickly, Han Du took a closer look. The gunpowder was very dry, with no sign of moisture at all, and it was pressed so tightly that he had to use a nail clip to pull it off.
