The Yun family has more days to celebrate than all the Tang people, the pomegranate needs to be celebrated when it is ripe, and the pear is ripe to celebrate, and now that the persimmon is ripe, it is natural to celebrate greatly.

"Yezi, I participated in your daughter's first cooking celebration last time, and I got stomach discomfort, can't I use persimmons to make a living today, right? Eating too much of this stuff is not good for going to the toilet! ”

Li Tai was tossed by the funeral of the Emperor Taishang, and set up a straw shed on the edge of the tomb and Li Chengqian, Li You, lived in it, it was supposed to be Li Er and his brothers to live in the grass shed, the emperor had complicated things, and lived for three days, so he let the prince replace them and returned to Chang'an by himself.

"There is something for you to eat, autumn is the time to stick to the fat, there are meatballs and strips of meat, and your favorite sweet rice is also steamed, you are not allowed to eat meat when guarding the tomb, you are a person who can't live without meat, eat more in a while, wipe your mouth clean when you leave before leaving, sweet rice and meatballs You can bring more to Chengqian and them."

Yun Ye and Li Tai talked, and Han Zhe took Yun Du to hold a long bamboo pole and twist persimmons down, this work Han Zhe had never done before, and now he was very happy to pick persimmons.

The cold weather in Guanzhong in November is pressing, except for the pines and cypresses and bamboos, the other trees are already bare, the persimmons of the Yun family bear relatively few this year, but they are very large, from a distance it looks like the trees are full of red lanterns, walk carefully under the persimmon tree, maybe there will be ripe persimmons falling and falling on the head.

"My research is in a predicament, Yezi, it's not a thing to do it behind closed doors, I just know that if you want to fly, you need to have a continuous and steady force on the object, but there are too many conditions required in the middle, and I immediately found that there are more problems to be explained when I solve a problem, and Hypatia is also helping me, but unfortunately there is not much progress.

When I was researching gunpowder, I discovered one of the properties of gunpowder, which is that it does not explode. It shoots flames and creates a forward force that I think can be used for flight,"

After finishing speaking, he beckoned, and immediately two servants wearing soft hats came over carrying a box, and Li Tai motioned for Yun Ye to go to the edge of the pond. The servant put a small wooden boat into the pond, the tail of the small wooden boat was tied with some thin bamboo pipes, under Li Tai's signal, the servant adjusted the rudder and ignited the lead on the bamboo pipe, the bamboo pipe in the middle began to spray flames, the boat slowly swam forward, the speed was very steady, as the lead continued to burn, the bamboo pipes at the two opposite corners also began to spray flames, the speed of the boat suddenly increased a lot, as more and more bamboo pipes were ignited. The speed of the boat became faster and faster, and when all the bamboo pipes were ignited, the speed of the boat was already very fast, and it was necessary to run quickly to catch up with the boat, and after a few runs, the gunpowder in the bamboo pipe was burned out, and the boat stopped motionless in the pond.

"That's it, the bow of the ship is cocked. If there is enough space for gunpowder, the ship will definitely fly. As long as the bamboo pipe alone is equipped with a tail fin, it can fly, and I have left this matter to my subordinates to study new firearms, and in the future, I may be able to cancel the Eight Ox crossbow, and there will be no need to install bulky crossbow arrows on ships, because gunpowder can fly weapons to enemy ships by itself, and I have no interest in studying how to kill. What I like more is how to fly into the sky, Yezi, how happy it would be to be above the white clouds. ”

Yun Ye wouldn't tell Li Tai that a guy named Wanhu had done this during the Ming Dynasty, but as a result, his bones were blown up. It was only rockets that used gunpowder as thrusters, and primitive airplanes did not fly like this.

"Yes, you've just made a big discovery just by starting your research, and if you continue to study like this, I'm worried that you'll fly to the moon one day, what do you do?"

Yun Ye couldn't dispel this hard-won enthusiasm for flying, so he could only continue to encourage him.

Li Tai said happily: "I plan to build a special boat, I will sit on it, tie a rocket to the back and try it on the Qujiang River, see if I can still fly." ”

"If you put two wings on the ship, I'm sure you'll be able to fly, but the problem is that I don't guarantee if you will land with your life after flying, gunpowder will explode, it's too dangerous."

Li Tai said with a smile: "If you can fly, you can land and fly, let's talk about it later, it's great I'll continue to get a pig up, hehe, the first one to take a parachute is a pig, I didn't expect the first one to fly up is a pig, I Li Tai didn't have a chance to have such a great moment." “

When the servant was igniting the gunpowder on the wooden boat just now, Han Zhe brought Yun Du over to watch, and now when he heard that Li Tai was planning to fly, it seemed that there was really such a possibility, so he couldn't help but interject and ask, "Can it really fly?" “

Yun Ye nodded and said: "It should be possible, the reason makes sense, it depends on the actual situation, ah, Qingque, I haven't reintroduced Han Zhe to you, he killed his father, and now he has the final say in Baishi Palace, this time Chang'an is selling cinnabar, Fang Xuanling's family can't eat those cinnabar, I heard that the palace is very useful, you see if you can eat the rest, it's the best cinnabar, I'm reluctant to sell it to those Taoist priests, they will only take it to alchemy and waste the good things." ”

Li Tai happily congratulated Han Zhe on killing his father, he knew about Han Zhe, if he had been put in Han Zhe's position, he would have gone crazy a long time ago, it was impossible to live to such a big age, Han Zhe took off his shackles in an instant, and the royal pressure disappeared in an instant, which is indeed a great thing worth congratulating.

"Xiao Zhe, now that the money is tightening the silver roots, it is difficult for me to take out a large amount of gold and silver to buy, but there is never a shortage of buyers for high-grade cinnabar, so I also want to exchange other things for huàn? You know, spices I still have. ”

Han Zhe thought for a while and said: "There is no need for spices, I need food, there is no food in Baishi Palace, I don't want to kill and rob, so I thought of redeeming some." ”

Yun Ye interjected with a smile: "Xiao Zhe, you are not a businessman, do you know how much grain you can exchange for these cinnabars?" As long as the population of your Baishi Palace does not exceed 10,000 people, which is enough for you to eat for twenty years, and the grain is not worth much in Datang, how can you get some food back? Don't tell me that the road to your White Stone Palace is very easy to walk, deep in the mountains and old forests, transportation is a big trouble.

Han Zhe absolutely believes that these two people will not lie to him, since this is the case, it must be the case, 10,000 people eat for 20 years, 1,600 people can eat at least 100 years? That's a terrifying number.

"Also, in Datang, such a large amount of grain trading has to be reported to the government for approval, and private individuals can't get so much grain, and you can't eat it, so it's better for you to take a part of the grain, that is, enough grain for you to eat for two years, and exchange the rest for some money, and the rest for spices, porcelain, glass, these things, and open a business house by yourself, so that you Baishi Palace will have a stable income, and you won't have to worry about small things like food in the future."

Han Zhe was very happy, he didn't expect the things he brought to be so valuable, he originally thought that he had brought twenty carts of cinnabar the size of mung beans, and it would be good to be able to exchange one hundred and ten carts of grain, but he didn't expect to be able to exchange so much, he didn't even have a shopkeeper on hand, so he could only hand it over to Yun Ye to help him deal with it.

Li Er soon knew about Han Zhe, he was happy to see Han Zhe kill his father, judging from Han Zhe's two years in Lingnan, he was more like a smart young man, rather than a vicious person, as long as Baishi Palace was willing to integrate into the Tang Dynasty society, Li Er was happy to see it, with the example of Baishi Palace, those annoying worldly masters would eventually slowly integrate into society.

No one knows better than Li Er the terrible consequences of marriage between close relatives, the royal family is also paying attention to the purity of blood, the White Stone Palace has come to the current stage, and destruction is almost the only foreseeable consequence for them, as long as the business name is established, they have no way to cut off their ties with the world, Li Er has crossed the White Stone Palace from his list of enemies in his heart, and ignoring it is the best way to deal with them.

Han Zhe specially wrote a sincere letterhead for this matter and handed it to Li Tai in the hope that it could be sent to the emperor's table, the arrogance of the Baishi Palace is still there, and it is impossible to surrender, but Han Zhe has promised that he will definitely abide by the existing system and respect the authority of the emperor in Datang, Li Er can see a lot of information from this letter, such as Baishi Palace is not in the land of the Tang Dynasty, although Han Zhe didn't say to anyone where Baishi Palace is, at least Li Er, Yun Ye, and Li Tai already know their approximate location, Because it can be deduced from the time and supplies they entered the Tang Dynasty.

Cinnabar is very in demand in Chang'an, after Yun Ye released a large number of cinnabar stocks in his hands, buyers flocked to him, and even the nobles also needed to keep some cinnabar for curing diseases, writing runes, and offering to the ancestors Cinnabar is also indispensable, because it also has a name called: "Immortal blood." “

Han Zhe piled up gold coins in the Yun family's guest room, he was not interested in these, but was very happy to help Li Tai prepare for the experiment that was about to start, and on the first day of the Yuan, he was going to test the first flight of human beings on the Qujiang River.

Han Zhe, who was bent on fighting with the pig for the right to ride for the first time, was scolded by Yun Ye fiercely, and he didn't intend to let people become victims of Shi Yàn until he was sure that he was absolutely safe.

The whole Chang'an people are looking forward to this flight, as long as it can fly, it is a big event that can go down in history, Li Er exempted Li Tai from the errand of guarding the tomb, let him concentrate on preparation, after his father died, he revoked the title of the sixteen families in one breath, the atmosphere in Chang'an is too depressing, and a little cheerful event is needed to ease it.
