Five dan of grain cost 20 wen per jin, 2,000 wen per dan, and 10 taels of silver for five dan.

Sixty catties of cured pork, eighty coins per catty, sixty catties and five ounces and eight mace.

Other items like salt and needles/thread will be provided free of charge; they're a complimentary gift from our shop.

That's a total of one hundred and sixty-five taels and eight mace. Forget the eight mace, you can just give me one hundred and sixty-five taels, is that alright?

The shopkeeper looked very imposing, his abacus clicked loudly, and it took him a long time to calculate the total.

Li Chang'an rolled his eyes as he waited.

Damn, that was a flurry of activity!

I don't need an abacus; I can calculate something in ten minutes, while you've spent at least two hours calculating it.

If you did this in modern times, you'd starve to death.

Su Xiao was faster than him. She counted on her fingers and secretly used her toes as well, and the number she got was exactly the same as the shopkeeper's.

Xiong Er and the others felt that what they were saying had gone beyond their knowledge and entered a realm they couldn't understand.

Li Chang'an took out a gold ingot and asked, "How much is this gold ingot worth?"

The shopkeeper's eyes lit up as he carefully took the gold ingot and examined it in his hand.

"It is of excellent quality and has a bright color. One gold ingot is worth at least twelve taels of silver."

One tael of gold could be exchanged for ten taels of silver.

However, a gold ingot of good quality and bright color can be worth eleven taels.

The gold in the system contains absolutely no other additives; it is pure gold.

It was even better than the gold ingots minted by the imperial court, so the shopkeeper quoted a high price of twelve taels.
