Shen Qingqian hurriedly sped up his hand-washing movements, and smiled at Qin Lao while turning around: "You are sitting in the first room, I will come over immediately." ”

Qin Lao's gaze was attracted by the various concrete materials piled together, and he raised his feet and walked over.

"What are you doing here? Playing with mud when you're so old? The latter sentence was said with a smile, and it was obviously a joke.

Shen Yong said quickly: "It's a method that the sixth sister saw in the book, and these things can be used to make mud that can be waterproof and windproof." ”

"Waterproof and windproof?" When Qin Lao heard this, he immediately became interested, "Is there really such a thing?" ”

Shen Yong proudly pointed to the half-finished product in front of the door of the house, "You go and take a look, we did the experiment before." ”

Qin Lao really walked over, knocked a small piece with a stone, and walked to the place where Shen Qingqian had washed his hands just now, and got the water up to observe.

After a long while, the dark gray pieces in his hands did not leak, and Qin Lao's eyes lit up.

"Good thing, this is good thing!" Qin Lao was so happy that the wrinkles on his face became deeper, and he almost danced.

Those who don't know how to do it may regard this thing as a sticky wall, but what he sees is the huge role of this thing in city defense.

It took him some effort to knock down such a small piece just now, and this is still made thin by the Shen family, what if it is made thicker and the area is larger?

Qin Lao is a person who is in charge of the weapons superintendent, isn't it just that they research weapons to better kill the enemy? But offense alone is not enough, defense is also very important. Therefore, seeing the concrete is like picking up a treasure.

Seeing that he was so excited, Shen Qingqian hurriedly gave Shen Xiao a look.

"Old Qin, let's eat first......" Shen Xiao let out a loud voice, wanting to pull Qin Lao out of his excitement.

But Qin Lao was even more excited, "What else are you eating?" If you tell the general about this, maybe you won't have to work in the fields again!" ”

When Shen Xiao heard this, his heart moved, and he wanted to say something, but when he thought that this was something that Shen Qingqian had made, he looked at her with some concern.

"Big brother, let's invite Elder Qin into the house first, and I'll talk about it later." Shen Qingqian was also thinking in his heart, but he was very calm on his face.

Their group of exiles is different from others, others may have committed some big crimes, or other reasons, but they are because of the struggle for the throne, as long as the one who is sitting on the dragon chair now, and does not want to let them go for a day, then no matter how much merit they make, it will be useless.

It was because of these considerations that Shen Qingqian did not think about taking this path.

However, this matter is not good, after all, the new emperor has only been on the throne for more than two months, and after a long time, he may be able to think of them, and then he can know his attitude.

Everything Shen Qingqian is doing now is just to make his family's life better, and as for getting rid of the status of an exile, he is really in a hurry.

Qin Lao also felt that what he said just now seemed to be too much, and after coming back to his senses, he entered the house by himself.

Then the little old man was attracted by the smell of the food on the table.

"What does this smell like? Why is it so fragrant? ”

If he hadn't seen Wu and them on the table, he would have wanted to taste it quickly.

Shen Xiao looked at Shen Qingqian, saw her nodding, and then sighed secretly and said, "It's a new seasoning made by the sixth sister." ”

He was very worried in his heart, since Qin Lao saw Shen Qingqian, it seemed that all the things that surprised and optimistic him were all related to Shen Qingqian, which really didn't know whether it was good or bad for her.

Hearing this, Old Qin was stunned, and his gaze at Shen Qingqian really changed.
