"Oh? What is it? Qin Lao's eyes immediately showed a light of expectation.

Shen Qing took out a drawing and handed it over, "I want to do this, and it will be convenient to ditch and plant after the spring." ”

I don't know what the reason is in this world, there has never been a cocoon, until now the sowing is sown by human hands, not to mention the waste of food, but also a waste of manpower.

Qin Lao took the drawings and looked at them carefully, and did not reply to Shen Qingqian's words for the time being.

The picture is a sketch of the cocoon that Shen Qingqian extracted from the "Encyclopedia of Farm Tools", but she has made some small changes according to the current situation, and the finished product will be more compact and lightweight.

After a while, Qin Lao looked up at Shen Qingqian, his expression was a little complicated, "You can draw this thing and ditch and plant at the same time, right?" ”

Why didn't he think of it?

In the past two years, every time he saw the exiles sowing seeds, he would feel wasteful, and he also thought about whether to make something out to reduce such waste, but the affairs of the ordnance supervisor often distracted him, and he was better at making weapons, and he was not familiar with this practical tool, so he had not been able to design something that satisfied him.

But when he saw Shen Qingqian's drawing, he suddenly became enlightened.

It's so smart to do two things with one tool and do two things at the same time!

"Well," Shen Qingqian nodded, and said without changing his face, "I also suddenly thought of it when I was doing laundry at home, and I thought at that time, if I could use both my feet and hands at the same time, wouldn't it be perfect?" ”

In a nutshell, make the most of it.

Of course, Shen Qingqian admired the ancestors of her world very much, and she was shocked when she first knew that the cocoon car actually appeared in the second century AD for the first time.

When she learned that there was not even a car in this world, her feeling was quite indescribable.

But it's relieved to think about it, after all, the overall level of industrial and technological development in this world is lower than that of her world.

"You girl is really ......" Qin Lao really couldn't cry or laugh, "It's obvious that you want to be lazy, right?" ”

Shen Qingqian said confidently: "Aren't most of the tools in this world invented by people for laziness?" ”

For example, the water reservoir is because I don't want to boil it when I want to drink water, the carriage doesn't want to be too tired to walk, and the pulley device in Chen Erlane is the same.

In modern times, there are more lazy products than mushrooms.

Qin Lao was choked by her and glared at her, "You have a lot of reasons!" ”

"Can you make this stuff for you?" Shen Qing asked with a smile.

Qin Lao snorted lightly: "Such a simple thing, what can't be done?" After speaking, he turned his head and gave the drawings to Chen Er, "You think about it first, and you will start making molds in the next two days." ”

Chen Er was stunned for a moment, and then said happily: "Okay, Master! ”

I didn't expect that Qin Lao would let him get in touch with the matter of making things so soon, and Chen Er felt a little stunned by good luck from the sky.

Shen Qingqian had the intention to help Chen Er, so naturally she wouldn't say anything, and she didn't mention whether the drawings should be kept secret or not, because she knew that Qin Lao would definitely find a way to promote the cocoon car.

She didn't feel at a loss, after all, the general who managed northern Hubei was Liang Cheng, no matter what his true attitude towards the Shen family was, as long as she made the Shen family more and more important, no one dared to touch them easily.

Doing two things at once, Shen Qingqian's heart was very relaxed, and when he came out of the ordnance prison, Shen Qingqian was not in a hurry to go home, but turned to the place where he did the accelerated fertilizer experiment last time.
