The news of the bumper rice harvest in the south soon reached Wang Haoran, and Li Shimin even gave amnesty to the world, and also prepared to hold a banquet in Chang'an to celebrate three days and three nights, and the curfew was lifted from 20 to 22 June. Wang Haoran naturally received an invitation letter, and before returning to Beijing, he called Chang Shusheng, Xiaoyu, Chen Jun and others, and there were some plans, and now it was time to start.

"Now you can start working on stone paint?" Chen Jun listened to Wang Haoran's plan, and immediately became excited, he had long coveted the fuel power that Wang Haoran said before.

"That's right." Wang Haoran said, "But before that, we have to research the technology to extract oil." I have already found the oil source, Chen Jie and Wen Shan, you can prepare, and the mining technology will be handed over to the two of you, and I will go with Uncle Chang in a while. This trip is very far, far away in the land of Bashu, and it is necessary to build factories, research equipment, etc., I am afraid that I will not be able to come back in a year and a half. When the time comes, I will arrange for all kinds of people to accompany you, work out the mining technology as soon as possible, and then come back to study fuel power. ”

"Yes!" Chen Jie and Zhao Wenshan received orders one by one like soldiers.

"Chen Jun, Li Tai, you will stay in Zhongcheng to study oil extraction technology and make the equipment." In private, Wang Haoran calls Li Tai's real name, if it is really about seniority, Li Tai has to call Wang Haoran uncle.

"Good!" Chen Jun and Li Tai replied.

"Xu Mian, I want you to study the fuel injection device first, that is, the liquid gasoline can become a mist after being sprayed out through the device, and I will explain the specific requirements to you in detail later."

"Yes." Xu Mian replied.

"Little Jade ......"

"Here!" Xiaoyu joined his brother's research and development team for the first time, and she was very excited, since she was called, she had been wondering what kind of work his brother would arrange for her, so as soon as his brother shouted her name, he gave a stirring call, and responded as neatly as a special team member.

Everyone laughed, and Xiaoyu was so embarrassed that her face turned red.

"Xiaoyu, you are responsible for researching the lighter, which will be used in conjunction with the fuel injection device in the future, and the role of the lighter is to ignite the oil mist sprayed by the fuel injection device......

"Do you use flint and steel?" Xiaoyu asked anxiously without waiting for Wang Haoran to finish speaking.

"No, it requires electricity. The voltage of the ceramic battery is too small to be used, so you can try it with a shaking power generator. ”

"What about me?" Yu Zizhao saw that Wang Haoran jumped to Xiaoyu after arranging other researchers, but he hadn't been assigned the task yet, so he hurriedly asked.

"You're on a team with me." Wang Haoran said, "We have experience in manufacturing steam-powered vehicles, and now the development of fuel power will be relatively simple, and the most difficult and indispensable is the ignition device, without this, everything is in vain." Therefore, in addition to Xiaoyu's research on the ignition device, Zizhao and I also have to study this, but in a chemical way. ”

"Can you generate electricity chemically?" Yu Zizhao asked.

"You don't need to generate electricity, you just need to be able to store it." Although Wang Haoran knew how to make chemical batteries, when Yu Zizhao was in charge of chemical research, he took down the names of many things that had not been named before under Wang Haoran's instructions, not only these, but also the various "new" metals that Xu Mian researched, and the physics involved in Wang Jingxiu all had things that they defined themselves, so some of the knowledge that Wang Haoran knew in later generations had to be reshuffled. In their defined knowledge, they are slowly catching up with Wang Haoran.

"So what's the use of my research?" Xiaoyu said in frustration, thinking that he was going to compete with his brother, and he was a little unhappy.

"Of course it works!" Wang Haoran explained: "Just like Zhaoyun, he often asks me when I can start studying flying cars, in fact, we have always been on the road of studying flying cars, and the new discoveries we have made now are the basis for studying flying cars. ”

"Can you really make a flying car?" Although Xiaoyu had heard Wang Haoran say this in private, she still didn't believe it, but this time his brother mentioned the possibility of making a flying car in front of everyone, coupled with the situation he had witnessed over the years, he began to believe it a little.

"Of course!" When it came to flying cars, Yu Zhaoyun became energetic, "Think about it, kites can fly in the sky, if the kite is several times bigger, or even dozens of times, then it can pull people up?" ”

"So how is it the same? Could it be that the flying car you are talking about is a big kite? Do you want someone to pull you on the ground? If the wind stops, then you just wait to be planted! "Xiaoyu is also energetic.

"Hey...... This is different, at this time, the downward line of the flying car can not be thought of as the line of pulling the kite, but as the downward weight of the flying car itself. As for whether there is wind, that's not a problem, as soon as the car runs, the faster it runs, the stronger the wind, so why worry about the wind stopping? Yu Zhaoyun is getting more and more energetic, before he asked others to discuss, at first everyone would follow the discussion, but after a lot of discussion, everyone was too annoyed to listen anymore, as soon as he mentioned this kind of problem, everyone hurriedly changed the topic, Xiaoyu's appearance, just like Yu Zhaoyun's savior, can be regarded as finding an object to nag about.

After Wang Haoran arranged everyone's work, he returned to Beijing again the next day, accompanied by Princess Nanchang. At this time, the railway from Zhongcheng to Puzhou had opened the manned business, and Wang Haoran and his party first made a steam-powered car to Puzhou, stayed in Wangjialou for one night and then hurried back to Chang'an. The day after he returned to Chang'an, Xu Xuanan brought his wife to visit, he was the first-line commander of the three-stone rice per mu, and naturally he was also invited by Li Shimin. Although he is now separated from Wang Hao and serves the imperial court, he has not forgotten who gave him all this.

On the day of the banquet, Xu Xuanan came to Wang's house early in the morning and went to the banquet with Wang Haoran. Li Shimin wants to have fun with the people, and the banquet venue is naturally not in the palace, but on Suzaku Street, where there is a big stage, and there are viewing platforms for the royal family and nobles in front of the stage, and the rest of the open space can be allowed for the people to come and go to watch the play, and there are many buffet-style sheds, where the common people can also receive free delicacies when they watch the play.

The sun on this day was scorching, but it was not as hot as the afterlife after global warming, and it did not stop the people's interest in watching the excitement.

The most solemn ceremony is the sacrifice to the sky, although the scorching sun, Li Shimin is still dressed in a grand costume, no one gives him an umbrella, and he reads the sacrifice on the high platform under the scorching sun.

There is also singing on the stage during the day, but it doesn't take long to sing, it's not for the common people, but for the gods, and the show for the common people is at night, after all, it's too hot during the day.
