time flies

Unknowingly, it has already arrived in May.

During this period, Zhu Youxiao did not go to court very much, but stayed in Yongding County. Today's Yongding County has also undergone earth-shaking changes.

According to Zhang Haogu's idea, the villages in Yongding County are basically clustered together, and the architectural styles of the houses are also similar.

All bricks and tiles, and the use of cement.

Nowadays, the people in Yongding County are living a relatively prosperous life. They already have enough money for consumption, and naturally they also pursue their own living conditions.

Nowadays, many brick factories have opened in Yongding County, and the sales volume is very good.

Zhang Haogu spent a lot of thought and formulated unified standards. The products produced were also hollow bricks, and the houses were particularly beautiful when built.

Zhu Youxiao has been here several times and is very satisfied with the place.

By the way, he also built a house here.

As a carpenter, Zhu Youxiao also designed this house himself, which gave him an indescribable sense of accomplishment and satisfaction.

It was as if he felt that the happiness he brought to him as the magistrate of Yongding County far exceeded the happiness of being an emperor.

However, now, Zhu Youxiao has resigned as the county magistrate of Yongding County. The magistrate of Yongding County is Zhou Jinyong. This person was one of the early students who joined Datong College and later became the owner of a farm. Later, he quickly

It has brought enough economic development to the farm owners.

Now he was appointed as the magistrate of Yongding County by Zhu Youxiao.

Zhou Jinyong also knew Zhu Youxiao's identity, and he was more or less excited. If Yongding County's economy developed, wouldn't Zhou Jinyong be able to prosper in the future?

Zhu Youxiao occasionally looks at the economic development of Yongding County. His greatest happiness now is to quickly build a steam engine.

Zhu Youxiao built himself a house behind the Institute of Science and Engineering.

Now the steam engine has also reached a critical moment.

"Steam engine, test 1378!"

Zhu Youxiao took a deep breath and glanced at the craftsman beside him: "Start heating!"

The steam engine now built by Zhu Youxiao is mainly used to pump water.

This is an egg-shaped container. First, the inside is filled with steam, then the steam inlet valve is closed, and cold water is sprayed outside the container to condense the steam in the container to form a vacuum.

Then open the water inlet valve, let the water be sucked into the container through the water inlet pipe under the action of atmospheric pressure, then close the water inlet valve, reopen the steam inlet valve, and use the steam pressure to force the water in the container out through the drain valve.

When the water in the container is drained and filled with steam, close the steam inlet valve and drain valve, and spray water again to condense the steam.

Repeat this cycle and use two egg-shaped containers to work alternately to achieve continuous drainage.

This was already a great improvement. Zhang Haogu was also staring at this test. He didn't know how long it took before he saw the water in the pool on one side being pumped out.

"Success!"

Zhu Youxiao suddenly became excited, and then hugged Zhang Haogu: "Master, master, look, I succeeded, I succeeded!"

Zhang Haogu also looked at the huge machine in front of him and couldn't help but smile: "Your Majesty, you are really a genius. Genius, it seems that you have really succeeded!"

"Master, next step, can I use it to build the train that the master mentioned, and also use the steam engine to make ships!" Zhu Youxiao looked at Zhang Haogu with bright eyes.

Zhang Haogu smiled and said: "Your Majesty, don't be anxious. What we need to do first is to combine the steam engine with the textile machine. This is also a troublesome matter. Your Majesty Rongchen wants to ask you a few questions!"

Zhu Youxiao looked at Zhang Haogu and said, "You ask!"

"Your Majesty, have you ever thought about why the pumping speed is so slow?" Zhang Haogu asked.

"This!" Zhu Youxiao fell into deep thought: "Master, what you mean is to speed up the pumping?"

Zhang Haogu smiled and said: "Your Majesty, the function of this steam engine is to introduce steam into the cylinder and then the valve is closed, and then cold water is poured into the cylinder. When the steam condenses, a vacuum is created. However, the thermal efficiency is very low. The reason is that when the steam enters the cylinder

, condensing on the cylinder wall that has just been cooled by water and losing a lot of heat!"

Zhu Youxiao pondered for a moment, and then quickly said: "I probably understand what the master means, which is to find a way to separate the cylinder wall of the condenser steam engine?"

"Yes, this is the next step!" Zhang Haogu nodded and said with a smile: "The next research direction is a separate condenser, an insulation layer outside the cylinder, lubricating the piston with oil, planetary gears, and parallel motion linkages.

Rod mechanisms, centrifugal governors, throttle valves, pressure gauges and more!”

Zhang Haogu suddenly burst out a series of words, which made Zhu Youxiao slightly stunned, and then said: "Master, how do you know so many things?"

"Your Majesty, I read a lot of books, but I am still willing to have a good discussion with the Emperor!" Zhang Haogu laughed. As long as the Watt steam engine is built, it can be used in industry. However, at that time, it is estimated that

It is no longer called the Watt steam engine, but the Apocalypse steam engine.

It's all the same anyway.

Zhu Youxiao fell into deep thought, then nodded and said: "Master, please tell me quickly!"

"Your Majesty, let's have something to eat first!" Zhang Haogu smiled and said slowly, "I have been staying here all night!"

"Okay, okay, let's eat!" Zhu Youxiao nodded and had two big white steamed buns delivered to him.

However, before I had eaten a few mouthfuls of steamed buns, suddenly, a loud noise came from the capital. In an instant, the ground shook, and even the entire Yongding County could feel the ground shaking slightly.

what's going on!

Zhu Youxiao suddenly stood up and looked in the direction of the capital, and saw a huge mushroom cloud rising slowly.

Zhang Haogu saw it in his eyes, and then sighed softly: "It's still here!"

A major event in the sixth year of Apocalypse, the Apocalypse Explosion!

At 9 a.m. on the sixth day of May in the sixth year of the Apocalypse, a bizarre explosion occurred in the area near the Wang Gongchang gunpowder depot in the southwest corner of the capital.

The explosion had a radius of approximately 750 meters and an area of ​​2.23 square kilometers, causing a total of more than 20,000 casualties. The cause of the explosion was unknown, the phenomenon was strange, and the disaster was huge. It was "unprecedented in ancient and modern times."

The Apocalypse Explosion, the "Dead Hill Incident" in ancient India, and the "Tunguska Explosion" in Siberia, Russia are known as the world's three natural mysteries.
