Steam is something that Gao Ming made out together with gunpowder and artillery in the second half of last year, and the craftsmen who participated in the production of these things are now in the newly established Tang Military Industry Department, protected by Gao Ming's cavalry guards.

Of course, it is okay to say surveillance.

As a certain great power said, the progress of science and technology is generally first applied to the military, in the case of steam, Gao Ming made the first one and then used it to install it on warships, and the second one was used to make the Beetle steam tank.

And both did not live up to Gao Ming's expectations and played an unparalleled role on the battlefield against Goguryeo.

Because of this, Li Shimin also attaches great importance to it, and the strictness of the Datang Military Industry Department is no less than that of the Inner Palace Forbidden Garden, and it is impossible for ordinary people to steal technology.

In fact, even if someone really has the power to steal gunpowder, cannon or steam technology, they don't dare to get it out of their own way, because if they are discovered, they will lose their heads.

Therefore, although Gao Ming knew that the Cui family would ask for something, he never thought that what the other party wanted was steam, and it was also a method of making steam.

So as soon as Cui Zhang's words fell, Gao Ming's expression suddenly became a little strange.

"You actually want the method of making steam, Cui Zhang, do you know what steam represents?"

In fact, Cui Zhang's heart was beating extremely fast at this moment, and after hearing Gao Ming's words, he immediately knelt down with a "poof".

"Weichen knows, but Weichen still hopes to get the steam and become the second Tang Dynasty Military Industry Department under His Royal Highness the Prince, and beg His Highness to agree!"

After saying that, he "banged" and slammed his head on the ground.

Seeing this scene, the corners of Gao Ming's mouth curled up slightly again.

"Is Datang's second military industry department? Originally, your Qinghe Cui family fought this idea! ”

Speaking of this, Gao Ming suddenly stood up, and then walked back and forth in the room for a few steps, as if thinking about something.

After a long time, he stopped, and then turned his head to look at Cui Zhang, who was kneeling on the ground.

"For the sake of Lu Guogong's face, I can hand over the method of making steam to you, and I can also allow you to become the second military industry department of Datang!"

"Really?" Hearing Gao Ming's words, Cui Zhang immediately raised his head, his face full of excitement: "Thank you, Your Royal Highness the Prince, Weichen ......"

"Don't be too busy just yet!"

Before he could finish speaking, Gao Ming raised up to interrupt him, and then squatted down in front of him, looking at Cui Zhang, who was kneeling on the ground.

"As the so-called Ming people don't say secret words, Cui Zhang, what are you going to exchange for these things, or rather, what are you going to exchange for these things in the Cui family, don't tell me about marriage, steam is not such a cheap thing!"

Gao Ming has long seen through these family gates, for them, it is common for them to exchange their daughters for political benefits, but in fact, this constraint on them is really too small.

So this time, Gao Ming decided their plan as soon as he opened his mouth.

Cui Zhang didn't expect Gao Ming to suddenly come to such a sentence, and he was stunned immediately.

"This ......"

Looking at his stunned appearance, Gao Ming's face suddenly looked a little unsightly.

"I mean, don't you really plan to trade your marriage for steam? Are you taking me for a fool? Well? ”

"No...... I...... This ......"

Cui Chang seemed to be planning to defend something, but he stammered and couldn't speak, and seeing this scene, Gao Ming's face became more and more gloomy.

"Lu Guogong, you ......"

Gao Ming originally planned to let Cheng Yanjin send off the guest, but what he didn't expect was that before he could finish speaking, Cheng Yanjin grabbed Cui Zhang's collar and gave him a slap with a "snap".

"Okay, you Cui Er, it doesn't matter if you play me, but you dare to play on the head of His Royal Highness the Prince, today Lao Tzu will not give you a look at the color, you still think Lao Tzu is a vegetarian!"

As he spoke, he slapped a few ears on it, and immediately hit Cui Zhang, screaming again and again.

"Ouch...... No...... Brother-in-law, don't move, you listen to me first...... Oops......"

"Stop talking nonsense, watch the fight!"

"Ahh

It wasn't until this time that Gao Ming reacted, it turned out that this Cui Zhang was Cheng Biting Jin's brother-in-law, but looking at Cheng Biting Jin's strength, the corners of Gao Ming's mouth suddenly twitched.

"Cheng Biting Jin, this guy, in order to get himself out, he really got down, those who know him know that he is beating his brother-in-law, and those who don't know think he is beating his son!"

Thinking of this, Gao Ming couldn't help but sigh suddenly, and then swung towards Cheng Yanjin, who was slapping Cui Zhang.

"Okay, okay, Lu Guogong, you live, just now I just wanted you to send Cui Zhang out, and I didn't blame you, what are you doing beating him? Cui Zhang, don't kneel, get up! ”

"Huh?" Hearing Gao Ming's words, Cheng Yanjin was immediately stunned: "His Royal Highness the Crown Prince just planned to let me send Cui Lao Er out?" ”

"Well, what else?"

“……”

Paralyzed, misspelled!

After realizing this, Cheng Yanjin suddenly let go of Cui Zhang's collar, and a trace of embarrassment flashed on his face.

"Uh...... That one...... Zitong, brother-in-law was impulsive, didn't hurt you, right? ”

Cui Zhang: "......"

How could it not hurt? How many times shall I hit you?

Feeling the hot pain on his left and right faces, Cui Zhang felt a grievance in his heart, and he bit his lip desperately to prevent the tears in his eyes from flowing out.

Gao Ming stood aside, looking at Cui Zhang's ravaged and ravaged appearance, and suddenly turned his head a little unbearable.

"It's not easy!"

When such a thing happened, Gao Ming couldn't let Cheng Yanjin drive Cui Zhang away, but it was a little embarrassing to stay like this, so it was better to leave now.

Thinking of this, Gao Ming immediately arched towards Cheng Biting Jin.

"Uncle Cheng, it's not too early, I should go back too, farewell!"

After speaking, Gao Ming walked towards the door, but before he could take two steps, Cui Zhang's voice came from behind him again.

"His Royal Highness the Prince, please stay!"

Hearing Cui Zhang's words, Gao Ming suddenly stopped, and then turned around with some confusion.

"Anything else?"

"Hmm!" Cui Zhang nodded immediately, then bowed to Gao Ming, and said, "Dare to ask His Royal Highness the Prince, what do our Cui family need to do to get steam?" ”

"It seems that the Cui family is quite persistent in steam!"

Looking at Cui Zhang's serious face, Gao Ming suddenly showed a smile of interest.

"Okay, then I'll give you a meeting, I hope that there are Tang Royal Academies in the four states of Yingzhou, Jizhou, Qizhou and Cangzhou, and the scale cannot be smaller than the Royal Academies in Jinzhou, Qinghe Cui Clan needs to contribute people, money, and efforts, if it can be done, what does it matter if the steam is handed over to Qinghe Cui Clan?"

"This ......"

Hearing Gao Ming's condition, Cui Zhang suddenly fell into thought.
