If you are really going to be shot down, should you use a parachute to protect yourself?
I don’t know how well Li Shimin prepared for Chang’an City’s air defense.
As long as an arrow is shot from the city wall, the hot air balloon, a cumbersome flying tool, is basically useless.
If the city defense of Chang'an City ignores a hot air balloon in the sky, it depends on whether they will consider the hot air balloon a threat.
Li Yue was in a bad mood and locked herself in the room.
Li Yue was originally passionate about hot air balloons, but now a basin of cold water was poured on her head.
It is true that there is an inexplicable sense of guilt in attacking one's own wife, but it is still necessary to punish her, at least to make her understand a little bit about the sinister nature of people's hearts.
Winter seems to have passed, and the weather has become much warmer these days.
Zhang Yang sorted out his experimental records and found that the burning metal compounds when the fireworks exploded were the source of the brilliance of the fireworks.
Mainly some metal compounds.
The easiest to obtain is copper, aluminum and magnesium.
If you are familiar with chemical formulas, it is not difficult to extract them. It just takes a lot of trouble.
As the old saying goes, if you learn mathematics, physics and chemistry well, you will have no fear of traveling all over the world.
After Li Yue locked herself in the room for a while, she came out again.
The little daughter-in-law was sitting in the yard with a straight face, staring at the spinach in the vegetable garden. She was very unhappy now and had an urge to eat all the spinach in the vegetable garden to vent her anger.
After organizing the experimental records, Zhang Yang was writing chemical equations.
Li Yue came over and saw these inexplicable equations and asked curiously: "What is this?"
"Chemical Equations."
"Equation? Is it the same as the formula I learned before?"
"There are similarities, but the calculations are different."
Zhang Yang said while writing: "To put it simply, this is a chemical formula. The process of chemical reactions of substances is expressed by equations. This also talks about the principles of substance generation and mass conservation."
Li Yue frowned, trying to understand.
Zhang Yang was still writing equations, and he was overwhelmed by the rows of equations.
"It's a little difficult to understand with your current abilities. I'll teach you slowly in the future."
Li Yue nodded slightly.
After writing a bunch of chemical equations, Zhang Yang said to Li Yue: "Actually, the vision of sitting in a hot air balloon and overlooking Chang'an City is not impossible to achieve."
"You will be shot down." Li Yue whispered, she had already accepted this fact.
Zhang Yang said with emotion: "Actually, if you use more wisdom in everything, it is not too difficult to accomplish it. When you encounter difficulties, you must solve them. As the old saying goes, there are always more solutions than difficulties."
"I know you are calling me stupid." Li Yue lowered her eyebrows and looked disappointed.
Zhang Yang smiled slightly and said, "At worst, we will trick King Wei into coming here and ask him to be our hostage."
Li Yue smiled, very gently. She knew that Zhang Yang would definitely help her. It didn't matter whether this method was good or bad.
After the couple got to know each other and got along, Li Yue believed in Zhang Yang and could definitely do whatever he said he could do.
Zhang Yang didn't want to offend Li Tai too much. After all, he couldn't treat people as fools. If Li Tai was also on the hot air balloon, at least he would be a little wary about whether to shoot him down.
Two couples laughing on a hot air balloon.
Li Tai is crying.
No matter how you think about it, this scene is a bit immoral.
After sweeping away the previous disappointment, Li Yue was once again full of hope for the future.
Zhang Yang watched his wife continue to draw the composition of the hot air balloon.
Li Yue is actually a very tough girl at heart.
Perhaps it was because of her poor health at a young age that she developed such a tough character.
The New Year's Day is getting closer and closer.
There are more and more people in Chang'an City. Zhuque Street is so busy that the whole Chang'an City seems to be packed with people.
The prosperous Tang Dynasty has already taken shape.
Half a month later, there are still a few days until New Year's Eve.
Li Tai's cake business was officially opened, and this time he asked the relatives of the servants in the mansion to handle the business.
After suffering the losses last time, Li Tai did a lot more concealment this time. Apart from collecting accounts and arranging personnel, he basically did not participate in business matters.
A shop was built on Zhuque Street, and the smell of cakes attracted many people on the day it opened.
Business was booming for a while.
Many people crowded in front of this store.
I watched several waiters in the store pour batter into an iron plate, close the two iron plates, and bake them repeatedly on the fire. After a while, the hot cakes came out of the oven.
The price is right, ten small cakes for ten cents.
The price is not cheap, but it is not unaffordable, and ten small cakes are enough to satisfy one's needs.
The supply even exceeded the demand, and they were all sold out in half a day.
Li Tai stood in the distance, eating a small cake, looking at the baskets of money in the store, his face full of excitement.
Now that they have money, the people of the Wei Palace finally don’t have to go hungry.
Zhang Yang is really my savior.
Li Tai sighed in his heart. He looked at the attendant beside him and asked, "How are you doing in the East Palace recently?"
The attendant replied: "I heard that the people in the East Palace can only drink porridge and eat dried vegetables every day. Not to mention how miserable the life is."
"Hahaha, really?" Li Tai, the little fat guy, smiled unkindly.
"I also heard that even His Highness the Crown Prince can only survive on porridge these days."
The smile on Li Tai's face grew stronger, "Tell the whole family that everyone will be rewarded with money today. You will not be hungry if you follow me."
The villain fell to his knees with a pop, his face full of loyalty, "We are willing to go through fire and water for His Majesty the King of Wei!"
The East Palace was not having a good time, and Li Tai was in a happy mood.
Li Tai threw a small cake into his mouth and thought about how much Zhang Yang still had to offer. This guy was really full of clever tricks. How could such a person live such a useless life? Why did the emperor's sister fall in love with him?
For this guy who has no ambition.
Come to think of it, this guy Zhang Yang has never read the books of sages, so he is really not the material to be an official.
Everyone has shortcomings, and no one can do everything well. Li Tai sighed like an adult: "Talents, what a pity."
The villain wondered: "What a pity."
Li Tai kicked his servant and said, "Hurry up and collect the money from me."
"Let's go, let's go." The villain was kicked roughly by Li Tai, and he went to the store to collect money with a smile.
Outside Lantian County, not far from Lishan Mountain, this store looks much deserted.
Zhang Yang sat in the store and looked at the account. The price of a barrel of batter was six guan. According to Li Tai's production frequency of ten barrels a day, he needed to pay sixty guan to the store every day.
The chickens are raised at home, and the eggs can be from wild pheasants or eggs from chickens in the store.
The cost of batter is very low, and the cost of materials is almost zero. A bucket of batter can earn you about 50 yuan.
Of course, Li Tai still owes money to the store. He needs to sell cakes to repay the debt. According to the current business boom.
It only takes about half a month for Li Tai to pay off the account.
