"I know I'm bad, you can laugh if you want to." Cao Ze said indifferently: "If something really goes wrong, I can't afford to take a real responsibility." ”

"Hahaha!" Cheng Yanjin couldn't hold it back anymore and laughed out loud.

"To be honest, I read the words of the immortal master today. Lao Cheng, my self-confidence came back all of a sudden. ”

"The word immortal master, it's really time to practice......" Although Li Shimin said it tactfully, the meaning was also obvious.

"Do I have any plans to fight any literati?" Cao Ze pouted indifferently.

But I'm still a little unhappy in my heart.

This is unbearable!

Start practicing calligraphy from now on!

At around four o'clock in the afternoon, Duan Lun came back in a carriage.

Cheng Yanjin and others helped move the coal stove parts into the house, and then waited for Cao Zexiu to operate.

Actually, there's nothing to do.

Considering the problem of screws, he asked Duan Lun to make the furnace body one.

Set up the iron rings on the stove, and the chimney is all over the place.

Because of technical problems, the chimney wall was built a little thicker.

But fortunately, it does not affect the use.

After commanding Cheng Biting Jin and them to install the chimney, they all lived.

In the afternoon, when he was talking about eggs, he arranged for Cheng Chumo to get some coal and come back.

After making a primer with a lunch box and cloth, Cao Ze added a little coal to it.

Because the lunch box is made of plastic, the smell is a bit big.

Li Shimin and the others covered their noses vigorously.

If they hadn't believed Cao Ze's words, they would have suspected that it was poisonous gas.

"Your Majesty, you have seen it too." Cao Ze gestured: "When the lunch box is burned, it will release harmful gases to people, and when the victims finish eating, you let people be taken back by the lunch box, and I will deal with it centrally." ”

Cao Ze found a new feature in the system space when he was bored before.

There's a destroy option in there, so you can dispose of things without leaving a trace.

"I see." Li Shimin nodded: "It's just ...... Sir, we all smelled this harmful thing just now, will it be ......? ”

"It's fine." Cao Ze was relieved: "Once or twice is nothing, it will cause harm to the body after a long time." ”

Little by little, time passed.

There was more and more coal in the furnace, and the temperature in the house was rising.

"The key to preventing poisoning is on this chimney." Cao Ze arranged for Chunxiang to get a pot of water and sit on the stove: "Now that these poisonous gases are discharged down the chimney to the outside of the house, people will naturally be fine." ”

"I see." Li Shimin and the others nodded suddenly.

"It's just like this......" Li Shimin seemed to remember something, and asked worriedly: "The poisonous gas is all emitted outside, and after a long time, won't everyone still be poisoned?" ”

"Don't worry about that." Cao Ze continued to be relieved: "This bit of poisonous gas is nothing to nature at all, and it will be purified automatically. When using it, pay attention to the tightness of the chimney and the connection to the stove. If you are really worried, you can wrap the sealing joint with mud. ”

After talking, the room was much warmer again.

"This coal stove is magical." Li Shimin shook his coat: "Now I feel a little hot." ”

"Sir." Li Shimin looked at Cao Ze and asked, "Then this coal stove, can it also be promoted?" ”

"Your Majesty......" Cao Ze looked embarrassed: "The promotion of the kang is naturally no problem, but this coal stove is ...... A bit of a hassle......"

"Actually, I came to Datang this time to do business." Cao Ze pointed to the surroundings and said, "You have also seen it, I am a newcomer, and my family is surrounded by walls, and I also have to eat......

Li Shimin and the others blinked in confusion.

Do you call such a mansion a home?

Do you have any misunderstanding of the word "four walls???

"That's easy to say." Li Shimin continued: "As long as it can benefit the people of Datang, the way is not a problem. ”

"Your Majesty has misunderstood." Cao Ze explained: "I mean that if Your Majesty promotes it, I can't let Your Majesty be busy in vain, right?" But if it's a profit split, I can't explain it to the other side, and it will cause me trouble......"

"Sir, this ......" Li Shimin's heart suddenly chuckled: "Now the people of the Tang Dynasty are suffering from the severe cold......"

Halfway through his words, Li Shimin stopped.

For Cao Ze, he didn't dare to make a direct request.

At least not yet.

But seeing that such a thing that benefits the people cannot be promoted, Li Shimin is extremely anxious in his heart.

Urging but not urging......

I could only look at Cao Ze with blank eyes......

Cao Ze's face was full of confusion, as if he was struggling and struggling fiercely in his heart.

A few minutes later.

"That's it!" Cao Ze gritted his teeth and said: "After Cao came, he was taken care of by His Majesty in many ways, and he was righteous for His Majesty, and today I will make this case for Your Majesty!" ”

"But I can only give His Majesty a net profit." Speaking of this, Cao Ze listened to it: "Yicheng is already the biggest limit, if there are more, I really can't hold back, and I hope Your Majesty will understand!" ”

In fact, Cao Ze is acting, and he is also tempting.

How can I say that I am an immortal now, and if I am too good to speak, my personality will collapse.

Forget about the kang, the coal stove can be used as a business.

I will definitely have to do a lot of business in the future, and if I give it away for nothing, I won't be able to mix it up later.

Otherwise, it's okay to give it away for free.

How much water is in this immortal, Li Shimin can probably guess some.

But it doesn't matter whether Li Shimin believes it or not.

What both sides need is their own reasons and steps.

If you want to hug Li Shimin's golden thigh, it is inevitable to make profits.

The bottom line in Cao Ze's heart is five or five, or even four or six.

The so-called bargaining.

If you say that you are profitable, Li Shimin will definitely not do it, right?

Pretending to commit a crime against the wind, everyone can get by on face, right?

And then after some nonsense, isn't this matter settled!

Perfect!

Cao Ze thought very well.

It's just that things have developed much beyond his expectations......

"No problem!" Li Shimin agreed very simply!

Cao Ze's face suddenly turned strange.

No?

Bargaining?

I'm asking for a price, and you're going to pay it back?

You're going to have to pay the price, aren't you?

As a result, you readily agreed?

You can't fix it for me, huh?

……

Egg pain is egg pain.

Since Li Shimin agreed, Cao Ze naturally wouldn't say anything stupidly.

Since you Li Shimin have no opinions, then let's open it for nineteen!

Thereupon.

Cao Ze 'endured the pain' and accepted this condition.

……

In fact, Li Shimin didn't think about it that much at all.

Ordinary people don't have the money to build coal stoves.

And it doesn't look very technical, everyone will look at it.

No matter how you look at it, it doesn't look like you can make money.

Anyway, my purpose is for merit, and making money or anything is secondary.

It's just spending money to buy technology from Cao Ze.

At least at this moment, that's what Li Shimin thinks.

And this idea and the beginning made him regret and feel distressed for a long, long time in the future......
