When Shen Qingqian took her improved Breaking Fever to Qin Lao, the entire Ezhou had already begun the second round of major cooling.

"Oh my God, girl, you really saved the old man's life!" Qin Lao didn't let go of the hot break, and looked at Shen Qingqian's eyes shining.

The temperature has dropped so badly in the past two days that he didn't dare to go out to the arsenal, and he was worried, so Shen Qingqian sent this thing.

Shen Qingqian said, "Don't always focus on the outside, it's still important to your own body." ”

"I know what you said, but how can I be idle? His Royal Highness and the general asked the arsenal to make as many weapons as possible, and when I heard that troops might be sent this winter, I couldn't wait to soak in the arsenal and not come back. ”

Qin Lao sighed, although he had not yet announced that he was going to fight, but no matter how cold the day was in the entire military camp, training had not fallen, and it seemed that something big was about to happen.

Shen Qingqian paused when he heard this, and his brows furrowed slightly.

Sheng Ze and they haven't returned to Huanxi Courtyard in the past few days, and she doesn't know what he is going to do after recovering his memory, is he going to fight again?

But if it's freezing today, how will this battle be fought?

Wrong!

Shen Qingqian raised his eyes sharply to look at Qin Lao, "Didn't the general say before that he wouldn't make a big move this winter?" Why are you going to send troops again all of a sudden? ”

And against whom to send troops? Do you have to send troops? What did Sheng Ze see in the Third World Realm?

"I don't know about this, and the old man doesn't have that much energy to worry about these things, but this thing," Qin Lao pointed and asked, "Girl, how did you do it?" Can you teach me? Can it be promoted in the military? ”

He asked a series of questions, and Shen Qingqian had no choice but to put aside the doubts in his heart for the time being, and explained in detail the principle of breaking heat and the materials that need to be used.

"Is that okay?" Qin Lao was speechless when he heard it, "Girl, how did you grow this brain?" How can you be so smart? ”

Shen Qingqian said helplessly: "Don't get me wrong, this is all mentioned in the books I read before, I just happened to find the materials to make it." ”

This involves the principle of chemical reaction in later generations, and she doesn't dare to pick up other people's achievements in advance.

"You still want to lie to the old man?" Qin Lao's eyes widened, "You try someone else, let him read the book and then make things to see?" ”

Just by looking at the book, you can make something mentioned in the book, which is not something that ordinary people can do.

From the description in the book to the actual creation of something, this process can kill most people in the world.

Shen Qingqian was dumbfounded, and didn't know how to explain it for a while, so he simply changed the topic, "Old Qin, I actually have something else to tell you when I came today." ”

"What's the matter? If you need my help to do something, you can say anything, as long as I can do it, I will not refuse. Qin Lao patted his chest. Chestnut Road.

Shen Qing pursed his lips and smiled lightly, "Thank you for your kindness, but I didn't come to ask you for help, but the weather has been cold these days, and when I was making this little thing, I thought of a way to heat a large area by the way, but I still need you to confirm it to see if it works." ”

"What's the idea?" Qin Lao became interested immediately.

In addition to burning coal in the army, there are actually more ways to heat ordinary people's homes, if Shen Qingqian can really solve this problem, it will really help a lot.

Shen Qingqian took out the paper that had been prepared a long time ago from his arms, "See if you can make this thing." ”

On the paper is a diagram of a boiler driving underfloor heating, and every detail is specially marked.

"That must be possible!" Qin Lao's eyes were even brighter than just now, and his face turned red from excitement.
