After several attempts, Jiang Qinyu didn't need to think much and directly chose "yes".

Then she saw an extra blank purchase box on the shopping mall's purchase page, where she could fill in what she wanted to buy.

Jiang Qinyu thought for a moment and wrote down "cotton" without hesitation.

She had cotton seeds, but there wasn't enough time; she could only buy finished cotton to make cotton-padded clothes.

The system quickly refreshed the page, and Jiang Qinyu breathed a sigh of relief when she saw the price of cotton.

One point can buy 100 kilograms of cotton!

Jiang Qinyu currently has several thousand points. Even if each person uses three catties of cotton, one point is enough for thirty-three people. That would be enough to give each border soldier a cotton-padded coat.

Of course, Jiang Qinyu was calculating based on the conditions of this world. In a world without cotton, clothes filled with three pounds of cotton would be warm enough.

Besides, she can earn more points if she doesn't have enough.

But now a new problem has arisen: how do we find the fabric to make cotton-padded clothes?

Lu Yanzheng remained on the city wall at the North Gate.

At this moment, he was wearing a cloak and facing the cold wind, looking out at the enemy camp outside the city.

"General, why don't you go and rest for a while? We'll keep watch here," Qin Shen advised.

Lu Yanzheng shook his head, "They could attack at any time, so we can't let our guard down."

"It's so cold now, and I didn't see them wearing thick clothes before. Surely they don't need to attack the city now?" Qin Shen asked hesitantly.

Lu Yanzheng looked at him and said, "The more impossible the situation, the greater the opportunity. This applies to us and to our enemies as well."

Just then, a commotion was heard from below the city walls...
