"Click......"

"Uh-huh......! Crisp and delicious, with a hint of fragrance, not bad! ”

After taking a bite, Fusu nodded, not too surprised.

"I still think canned lychees are the best fruit!"

After a mouthful, Fusu raised his head and said.

"Haha! Brother Huang, you eat the shell of watermelon, it's strange if it tastes good! ”

Xiao Zhengtai couldn't help it and laughed out loud.

"Shell? Is this emerald green shell? ”

Fusu held the watermelon in his hand and looked at it suspiciously.

"Or else?"

Xiao Zhengtai took a bite on the red watermelon pulp, and the sweet and refreshing taste suddenly swept through the body, revealing an expression of enjoyment.

"I see!"

Following his example, Fu Su also took a big bite of the piece in his hand, and suddenly squinted his eyes, "Well, it's delicious, it's even better than canned lychees!" ”

In the hot summer, eating canned lychees will inevitably feel too sweet and greasy.

But watermelon is different, very refreshing!

"I'm not wrong, am I? Watermelon has plenty of moisture and is definitely no worse than lychee! ”

Xiao Zhengtai's speed was very fast, and after a while, he finished a piece of watermelon, and a row of black seeds had been spit into his hands.

In a matter of moments, a huge watermelon has been eaten by the two of them, and only a bag of watermelon seeds has been taken away!

……

"Little boy, just now Zuo Cheng Huang Yuan, who will be the supervisor, came here and said that the steam engine was successfully manufactured!"

After Fusu left, Xiao Zheng slept for a while, and as soon as he opened his eyes, Jingfu opened his mouth to report.

"Oh? Where is he? ”

Xiao Zhengtai rubbed his eyes and asked.

"I heard that you were asleep, so I went back first, saying that I should keep an eye on it, and don't make any mistakes!"

"Alright, got it!"

Xiao Zhengtai nodded, changed his clothes, and took a carriage to the steel mill.

With the gradual increase in demand for steel, the steel mill has also expanded and expanded, and now it has formed a scale.

The steam engine needed a lot of steel, so I simply found an empty factory in the steel mill and studied it!

When Xiao Zhengtai arrived at the steel mill, the outside of the factory where the steam engine was studied was already surrounded by water.

Almost all the craftsmen in the steel mill came to watch.

Before Xiao Zhengtai came to the palace, Da Qin didn't say that it was steel, and even the output of iron was very small!

Usually some hoes, ploughs, weapons and the like are made, and this is the first time to build precision instruments!

I heard that the ignition experiment was about to be ignited, so everyone gathered here!

The craftsmen who are only in the manufacture are even more dumbfounded!

I've been working day and night for so long, and I don't know if it can work?

"Little boy is ......!"

With a snort, the craftsman blocking the door immediately made way for Xiao Zhengtai to pass smoothly.

"Little boy, look, are you still right?"

Huang Yuan stretched out his hand and respectfully made a gesture of please.

No one has ever seen this thing called a steam engine, and he also draws a gourd in the same way, whether it is right or not, he doesn't know.

And no one had tested it before!

"Hmmm! It's pretty much the same in appearance! ”

Xiao Zhengtai turned around the steam engine with a happy face and nodded.

Not to mention, Huang Yuan's craftsmanship is not bad, it has only been half a year's work, and the steam engine has been researched.

In fact, he had never seen a real steam engine, only a few pictures.

Looking at the appearance, it should be about the same, but I don't know if it can work normally!

"Let's light the fire!"

As soon as Xiao Zhengtai gave the order, the craftsman set the coal prepared before on fire and began to test.

Everyone present waited for the water to boil, and the atmosphere did not dare to breathe.

It didn't take long for the water in the boiler to heat up and start to bubble.

Gradually, a small flywheel on the steam engine began to turn, which proved that the water vapor in the boiler had begun to work.

Slowly, the flywheel spun faster and faster, and everyone cheered, "Great, successful, really successful!" ”

“Yes！”

Even Xiao Zhengtai jumped for joy.

The steam engine was the core of the first industrial revolution, which could replace human power and convert the energy of steam into reciprocating power for mechanical work.

With the steam engine, the next steam train, steam warship, and steam loom can all be studied one by one!

"From now on, give me the steam engine to produce in large quantities, and build as much as you can!"

"No problem, it's just that the number of craftsmen is not enough now, if it is mass production, maybe we have to recruit more!"

"You can do this, if you need money, go to Yu Wenxuan!"

"Yes!"

Huang Yuan replied.

"How's the last study of your warship drawings?"

"Little boy don't ask, I'm also trying to report it!"

"Oh?"

"Thanks to the little boy, relying on this drawing, I also earned more than 2,000 Wen!"

At the mention of this, Huang Yuan was full of smiles.

"Make money? You're not going to sell my boy's drawings, are you? ”

Xiao Zhengtai sighed in his heart.

Warships are a sharp weapon for going to sea, and they can withstand the strong winds and waves of the ocean.

After researching the warship, he will instigate the scumbag to send troops to conquer those overseas islands.

If it flows into the hands of foreign races and is used against them Daqin, won't it be like lifting a stone to shoot yourself in the foot?

"No, no, no, how can this ......?"

Huang Yuan waved his hand again and again, and explained with a smile, "The drawings given by the little prince are very clear, the entire ship is made of steel, and after the craftsmen who built the building boat were gathered together, they didn't believe that the steel ship could float on the water, so they made a bet with the lower official to build a simple boat according to the method on the drawing, and try to see if it would sink!" ”

"If they sink, the lower officials will lose to them, but if they can float, then they will lose to the lower officials!"

"As a result, the small boat made of steel was put into the water, and it really floated, and it was very smooth, not like a wooden boat!"

"Xia Guan also used this method to win more than 2,000 Wen, haha!"

The more Huang Yuan spoke, the more excited he became, and finally burst out laughing.

"Hoo ......"

Hearing this, Xiao Zhengtai finally breathed a sigh of relief.

It really scared him just now.

I thought this guy had sold the drawings he had worked so hard to draw for the sake of money!

But calm down and think about it, it's really impossible, if it is really sold, this guy will not be able to stand here now, he must have run away with the money!

"Next time, don't gasp for breath, I'll scare the master to death!"

Xiao Zhengtai patted his chest and gave him a blank look.

"Okay!"

Huang Yuan grinned and nodded.

"Then again, when you get the drawings, aren't you questioning whether a ship made of steel can float, why can you win when you bet?"

Xiao Zhengtai suddenly thought of the scene where he handed over the drawings to Huang Yuan before he set out for the expedition.

At that time, this guy was also full of doubts, and he didn't believe that the iron ship could float on the water!
