Although Zhang Qinghua was very angry, he didn't dare to show it too obviously because he thought of the Bai family behind Jiang Wanwan.

They dared not make things difficult for Jiang Wanwan.

He took a deep breath and kept reassuring himself.

There's plenty of time; he's determined to find a way to deal with Jiang Wanwan.

Zhang Qinghua forced a smile, "Hehehe, since that's the case, then we'll just have to wait for my niece to develop a new type of mosquito coil."

"Uncle Qinghua, don't worry, I will definitely work hard to develop a new type of mosquito coil. Once it's developed, I'll give it to you to try as soon as possible. Everyone else can step aside," Jiang Wanwan said readily.

Zhang Qinghua's teeth ached when he heard this.

He thought to himself, "Once she develops a new mosquito coil, Baibaoxuan's business will probably be completely taken over by Wanhuofang!"

It seems he still needs to find another way to crack the mosquito coil formula. This way, he can not only severely damage Jiang Wanwan's business but also preserve Baibaoxuan's position.

A glint of light flashed in Zhang Qinghua's eyes, and he smiled, "Thank you in advance, my dear niece."

Both harboring their own ulterior motives, they chatted for a while longer before Jiang Wanwan finally took her leave.

"Uncle Qinghua, just wait for my good news. I'll definitely bring you new mosquito coils next time." Jiang Wanwan clasped her hands in a fist and palm salute, and Zhang Qinghua saw them to the door.

"Alright, I'll wait for my niece's good news," Zhang Qinghua said with a forced smile, appearing extremely hypocritical.

Uncle Jiang cracked his whip, and the yellow ox slowly lifted its head and walked away.

Zhang Qinghua and Xiao Wang stood at the door watching Jiang Wanwan leave. Only after Jiang Wanwan's figure disappeared did Xiao Wang breathe a sigh of relief. He said with a smile, "Manager, that's wonderful. Once Miss Jiang finishes developing the new mosquito coil, our Baibaoxuan business will surely return to what it was before."

"Hmph, I'll see how long Wanhuofang can keep laughing. They have mosquito coils, and so does our shop, and they're even the newest kind! Our business is sure to be even better than before!"

Zhang Qinghua turned around, raised his hand and slapped Xiao Wang hard on the forehead, glaring at him angrily and cursing, "What's so good about it! Didn't you see that that brat Jiang Wanwan has no intention of cooperating with us at all?"

I ordered a batch of mosquito coils from her, but she kept making excuses. I offered her three times the price, yet she was ungrateful and refused to cooperate. What else could she be doing but doing it on purpose?

Developing a new type of mosquito coil is just an excuse for her. Whether or not she actually develops it is entirely up to her. What if she says it will take a month, six months, or a year to develop it?

We can't let a mere young girl like her lead us by the nose!

Upon hearing this, Xiao Wang was furious. "How could Miss Jiang do this! The shopkeeper has already offered three times the price, which is already very sincere, yet she still refuses to cooperate out of kindness."

What's the point of partnering with Wanhuofang? Wanhuofang is just a small shop that's been overshadowed by Baibaoxuan. Isn't it obvious who we should partner with?

"Shopkeeper, you're right. Since Miss Jiang is so ungrateful, we can't just sit here and wait to be killed. We should teach her a lesson. What should we do next?"

Zhang Qinghua squinted his eyes and pondered for a while before speaking, "Send someone to Wanhuofang and Ruixiangju to buy a few rolls of mosquito coils each. Then find a group of craftsmen who make incense powder, preferably those with a sensitive nose, and have them develop a secret formula for mosquito coils!"
