Gu Chengfeng remained silent, recalling her clumsy and laborious appearance just now.

It's still too delicate; it can't even saw a piece of wood.

Such soft hands, such a slender waist, what if they get hurt?

With a dark expression, he picked up the design drawings from the side.

Looking at the neat and clear lines and the precise dimensions, he could tell at a glance that it was a small cart based on the lever principle.

A hint of surprise flashed in his eyes: "You drew this?"

She nodded thoughtfully: "Yes."

Gu Chengfeng didn't pry into why she was making it, but simply asked, "How heavy do you want to lift with it?"

Shen Sisi's eyes lit up. Gu Chengfeng was quite something; he could tell at a glance that she was meant to carry heavy objects.

She thought about it carefully and said, "More than two hundred jin."

He was puzzled. Did this house really contain more than 200 kilograms of stuff?

However, he didn't say anything more, but pointed out an unreasonable point: "For something weighing over 200 pounds, the length of your lever is a bit short, and a wooden cart is not the same as an iron cart. You need to consider the actual situation."

Gu Chengfeng not only recognized it as a lever, but also pointed out her mistake, leaving Chen Sisi in awe.

Gu Chengfeng was always at the bottom of his class in school, and all he did was cause trouble.

I never imagined he would know so much after only a few years in the army.

Indeed, the men cultivated by the state are truly excellent!

Gu Chengfeng carefully glanced at the letter, then gestured for Chen Sisi and Niu Niu to step aside: "Leave it to me, I'll make it for you..."

As he spoke, he took off his green military overcoat, revealing the green military uniform underneath.

With the blueprints tucked between his legs, Gu Chengfeng unbuttoned his top button with one hand, revealing his sexy neck.

The buttons on the sleeves were quietly undone, and the sleeves were rolled up evenly, revealing the well-defined wrists and the old scars on them.

Shen Sisi noticed the scar again. If she remembered correctly, it was the place where Gu Chengfeng was cut by a stone when he saved her years ago...
