Hearing Liu Qing's anxious calls, Xiao He quickly put down what she was holding and brought her a tinderbox.

"Shopkeeper, here you go." Xiaohe handed the tinderbox to Liu Qing.

Liu Qing took the tinderbox, moved gracefully, and turned back into the house. She deftly uncorked the tinderbox, puffed out her cheeks, and blew on the dim tinderbox to light it. Then she lit the sandalwood-scented mosquito coil.

Gradually, a wisp of gray smoke rose, like a light veil or mist, spreading outwards and carrying a faint sandalwood scent that began to permeate the entire room.

The entire room was instantly enveloped in a tranquil and rustic atmosphere.

Liu Qing's eyes lit up as she looked at the mosquito coil in her hand, her body trembling slightly with excitement. "Sister, this mosquito coil... it's absolutely wonderful!"

My sister is such a talented girl; it's amazing that you could invent such a wonderful mosquito coil.

Liu Qing praised it highly, taking a deep breath to suppress her excitement. "Sister, how much do you charge for these mosquito coils?"

No matter the cost, she had to get this mosquito coil!

This mosquito coil not only repels mosquitoes, but also satisfies the needs of those wealthy people who want to use incense – it's a win-win situation!

There's no shortage of market demand for mosquito coils like these.

She quickly signed a contract with Jiang Wanwan, stipulating that this mosquito coil could only be sold to her in the county town, and no other shops could sell it!

Jiang Wanwan raised an eyebrow, "Sister, shouldn't you try it out first? You trust your younger sister's mosquito coils that much? Aren't you afraid they won't be effective at repelling mosquitoes?"

Liu Qing's phoenix eyes curved into a smile, and the corners of her mouth turned up high. "Of course, I trust you, sister. You are of excellent character, and you would never make such a shoddy item to fool me."

Besides, if I don't act now, won't someone else snatch up this new mosquito coil and sign a contract first? Then, when I want to buy it later, I won't be able to get it anymore.

At the end, Liu Qing winked charmingly and said with a smile, "Little sister, am I right or wrong?"

Mosquito coils are extremely popular in the county nowadays, and whoever seizes this opportunity can make a fortune.

She was certain that if anyone recognized Jiang Wanwan as the supplier of mosquito coils, many shop owners would be eager to have her visit their stores.

"Of course not. Back when mosquito coils weren't popular yet, it was Sister Liu who took the risk to place an order with me. We should never forget those who helped us. I understand that principle," Jiang Wanwan said politely.

Then she continued, "Sister, you've been dealing with incense powder for years, so you must know how valuable it is. However, since we get along so well, how about I sell a roll of sandalwood mosquito coil for only eight coins?"

Ancient spices were indeed expensive, but modern ones aren't. A pound of sandalwood powder only costs a little over five yuan in the mall. If you calculate it that way, she can actually make quite a bit of money.

Liu Qing looked at Jiang Wanwan in surprise, hesitated for a long time before finally saying, "Little sister, won't you lose money selling it so cheaply?"

Good heavens, she thought a scroll would cost at least ten or more coins, but it only cost eight coins.

Liu Qing felt a pang of pity, thinking that the little girl must have considered her like a sister to offer her such a low price.

Since the girl is so loyal, she can't feel too guilty.
