Becoming a stepmother of three children gives me space

Chapter 199 The Emperor's Black Face, Wu Chunfeng's Talent

The next morning,

According to the agreement, the emperor appointed Dabao as the King of Qin, with the fief of Guanzhong, 10,000 households, and one guard in the palace. After he came of age, he would go to the fief to be a vassal.

Before he came of age, he lived in the capital and was given a house, ten thousand taels of gold, and a number of treasures. He was also allowed to live outside the palace.

Xiaobao was granted the title of Prince and Niuniu was granted the title of Princess. They were each given a fief of 5000 households, a mansion, 1,000 taels of gold, and some treasures, and were allowed to live outside the palace.

The people in the court are all cunning.

The rewards given by the emperor were very generous and also came with privileges. It seemed like favor, but in fact it was compensation for depriving him of the title of Crown Prince.

Zhou Jin, the legendary stepmother who found the person, was not rewarded. The emperor was dissatisfied and completely excluded Dabao from the heir to the throne!

Some people thought that the court did not change the situation because of Dabao's return, but they soon discovered that things were not as they imagined.

"The construction of the new city is imminent. I have discussed with the cabinet that all princes are eligible to participate in the competition. For the sake of fairness, I and the cabinet have decided to conduct an assessment."

The three major camps in the capital and the new camps of the upper twelve guards, a total of six, will be supervised by six princes respectively. The prince with the most outstanding achievements will be responsible for the construction of the new city. "

A minister stepped forward and asked:

"Are there any specific standards for the assessment of grades?"

"Quality comes first. If the quality is the same, the one with the lower cost wins. If the cost and quality are the same, the one with the shorter construction period wins."

"Are all princes eligible to participate in the competition?"

"Of course... However, there are many princes, and there are only six barracks. If there are too many candidates, the ministers will select six..."

Zhao Zhen was the first to step forward, followed by the third prince, the fourth prince, and the adult princes one after another. At this time, Dabao also stood up.

The emperor was stunned for a moment, then he remembered that Dabao had just been canonized as a prince and was theoretically eligible to participate in the competition.

"The King of Qin is young, so he doesn't need to participate."

The first thing he did was to refuse. He would not give Dabao a chance in the battle for the crown prince.

A stubborn censor stood up and accused:

"Your Majesty, your words are true. Even princes are qualified. How can you change your mind overnight?"

What is meant by "shooting oneself in the foot"? It is indeed inappropriate to easily change what the emperor said. Anyway, there are more than six people.

Among the candidates recommended by the ministers, no one will choose Dabao, so there is no need to worry at all.

clap clap,

Soon the emperor's face was swollen from being beaten, and Dabao was successfully selected. Most of the ministers who recommended Dabao were his confidants, and they almost vomited blood in anger.

Zhou Jin sneered in the crowd.

He knew the emperor's character too well and knew that he would not easily restore Dabao to the position of crown prince, so when Dabao agreed to be named King of Qin in the imperial study, he did not argue.

Being a prince means having fiefdoms, fiefs, personal guards, and being able to live outside the palace. Apart from the disadvantage of being legitimate, he has more freedom and more room for maneuver than the crown prince.

The weak cater to history, the strong write history. Zhou Jin never pinned his hopes on the emperor's mercy and conscience.

The emperor was stabbed in the back and was very angry. After leaving the court, he called all the officials who supported Dabao to the imperial study and criticized them severely.

"Your Majesty, please calm down. I am doing this for the sake of the country and to share your worries."

"Shall I thank you again?"

"The King of Qin has returned to the court and wants to take action. If Your Majesty forcibly stops him, what will the people think? The people in the northwest are grateful to the King of Qin, and the resettlement of refugees requires his cooperation. If this is too embarrassing, it will be detrimental to Your Majesty if it gets out."

The emperor is the one who listens to advice.

Forcibly preventing Dabao from participating would indeed give him a bad reputation, especially since he was planning to reap the benefits and suppress Dabao everywhere. The refugees in the northwest would inevitably resist.

Dabao has just arrived, and the construction of the new military camp requires a large amount of building materials and manpower. Even if the Shen and Zhou families help, it is unlikely to win.

"That's it!"

The emperor thought so and didn't worry about it anymore.

.....

Xiao Mansion,

After Xiao Yunxi checked the children's homework and announced the end of school, Wu Chunfeng came over happily from the back.

"Master's Wife, the buoyancy you just mentioned is based on the same principle as the bottle swallowing the egg. When the oxygen in the bottle burns out, the density decreases, the pressure decreases, and the egg is pressed in. The hot air balloon you mentioned also burns out the air in the ball, the density decreases, and it will float, right?"

Taoists are good at numerology, and in the process of alchemy, they are also the enlightenment of chemistry. They have summarized and studied many natural phenomena, but what they lack is the support of theoretical knowledge.

The booklet Xiao Yunxi gave him made up for this shortcoming. Wu Chunfeng had already gotten started and could draw inferences from one instance. He could associate the hot air balloon's principle with the bottle swallowing the egg.

If he is given enough time, he might be able to complete the process of the industrial revolution in a short period of time.

Dabao and the children are still young, and Zhou Jin has a lot of things to do. In the research and development matter, perhaps Wu Chunfeng can give her more help.

"The principle of a hot air balloon is similar to that of a bottle swallowing an egg, but the basic principles are different. The former is a matter of buoyancy, while the latter is a matter of pressure..."

Wu Chunfeng quickly opened the booklet Xiao Yunxi gave him and nodded:

"Indeed...it's both changes in air density, but the principles are different...so can this hot air balloon really fly? And can it carry people to great heights?"

The flight altitude of a hot air balloon is affected by wind speed, wind direction, temperature and air pressure.

Under normal circumstances, the flight altitude of a hot air balloon is about 1000 meters. The clouds are thin and the visibility is high, so the hot air balloon can pass through the clouds and reach higher altitudes.

The highest altitude a hot air balloon can fly is over 30,000 meters. It can indeed reach 10,000 meters, but the highest record for humans riding a hot air balloon seems to be 20,000 meters.

That was done with special equipment. Without equipment, the limit is estimated to be 10,000 meters, which is still far away.

"Theoretically, a hot air balloon can reach heights of thousands of feet, but achieving this isn't easy... A hot air balloon is essentially a large-scale Kongming lantern. To have enough buoyancy to carry people, the balloon needs to be as large as possible. However, the larger the balloon, the heavier the material... To overcome its own weight and the load it carries, the material needed to make the balloon needs to be both strong and lightweight..."

Wu Chunfeng jumped up:

"The skin of a big fish is strong and light enough!"

Everyone has learned to answer quickly.

The big fish is the whale, which was recorded hundreds of years ago.

Whales are huge fish in the sea. They can swallow boats across the sea. They burrow in the seabed. When they come out of their burrow, the water overflows. This is called whale tide.

Whales have many uses.

Fish meat is edible, and fish bones and fish oil can be used to make candles and lamp oil. Fish bones can also be used as medicine and even made into beams for bridges and houses.

However, we currently do not have the ability to capture them, and most of them are caught after being stranded, relying entirely on luck.

As early as in the northwest, Zhou Jin sent people to look for it, but to no avail. However, the rubber and rubber trees had been delivered, and they were just waiting for Dabao and the others to come back.
