Da Qin: The First Emperor wanted to train me to be the empress

After hearing their father's instructions, Zhenman, Yinman and Xuman both stepped forward and quickly added water to light the fire. It didn't take long for the water in the furnace to boil and produce steam.

As the steam pressure increases, the originally stationary gear begins to rotate slowly, from slow to fast, until a balance is achieved and it stops accelerating.

Because the bucket holding water is not big, water needs to be added constantly, and firewood below also needs to be added constantly, which is a bit troublesome.

But even so, Xu Man couldn't help but laugh.

At this time, everyone had not yet fully utilized the role of coal, so my eighth sister did not think about it.

It is already extraordinary to achieve such an effect in the early stage.

So Xuman clapped his hands with satisfaction: "Congratulations to the emperor, congratulations to the eighth sister, this steam engine is a success."

When several important ministers heard what Her Royal Highness the Princess said, they also clapped and said congratulations: "Congratulations, Your Majesty, Congratulations to Princess Yunxiang."

Ying Zheng listened happily, his eyes were shining, and he wanted to know where this thing could be used?

When can I travel around the world in one year?

Naturally, he happily replied to everyone: "Same joy."

Zhenman discovered several problems through the experiment just now: "It's just that the firepower is insufficient. If it is really used, the firewood will not be enough to burn."

"What's so difficult about this?"

Yin Man smiled and said, "Eighth Sister, have you forgotten the role of the coal provided by Ninth Sister?"

As soon as these words came out, Zhenman's eyes lit up: "Yes, I actually forgot about this."

Xu Man: "It's not that you forgot, you just didn't remember it for a moment."

"Also, the container for holding water needs to be enlarged and deepened, and the stove for burning fire below must also be enlarged proportionately."

Zhenman said seriously: "Yeah, listen to Jiu Mei, if you want to burn charcoal, you have to modify the stove, otherwise the ashes produced after burning cannot be processed."

The three sisters had a lively discussion and conducted a comprehensive analysis from all aspects.

Ying Zheng and several important ministers heard these things and understood them only half-understood.

At that moment, Mo Yuan and Gong Shutong pricked up their ears and listened with great interest. They even took out pens and notebooks from their sleeve pockets to record key information. At the end of the discussion, Xu Man said to Zhen Man encouragingly: "Sister Eight, everything is difficult at the beginning. If you make this start today, it will be much easier to improve and optimize in the future."

"Come on, keep an eye on you."

"Yes, Eighth Sister, I didn't even think that you could use the steam produced by boiling water."

Yin Man also looked at Xu Man with emotion, "By the way, Sister Jiu, where can this thing be used?"

"It can be used on boats to make boats faster, on cars to speed up cars, and even to drive very long cars that can accommodate many people."

Xu Man responded casually, "You can even use it as power to make things fly in the sky. In short, it has many uses."

"Wow, that's amazing."

Yin Man's eyes were filled with confusion after hearing this, and she was so excited, "Eighth Sister is so amazing."

Zhenman also didn't expect that this thing she had researched would be of such great use.

His face turned red with joy and he nodded repeatedly: "Great, I can finally contribute to Da Qin."

"Eighth sister, you have always contributed to Daqin."

Xu Man hugged the Eighth Sister's shoulders, not to mention that he liked her very much, "You are our first scientist in Great Qin."

"What is a 'scientist'?"

Ying Zheng listened to the conversation between several girls, and the smile never broke off his face. Suddenly he heard a new word, and he quickly answered it.

Not only Zulong was curious about the meaning of this word, but everyone else looked at Her Royal Highness with curious eyes.

Their Royal Highness seemed to know a lot of things, more than they could imagine.
