The father and daughter stopped talking and each showed off the noodles in their bowls.

After eating a few bites of noodles, Jiang Wanwan suddenly remembered the mosquito coil incident.

After conducting market research, she concluded that mosquito coils had a significant market presence in ancient times.

However, she seems...likely...not knowing how to make mosquito coils!

That's awkward.

Jiang Wanwan slowed down her eating pace, then thought of her cheat code.

So, while her adoptive father was eating noodles, she switched the floating panel in front of her to the online store page.

She tried entering "traditional mosquito coil making method" into the search bar of the online store, and different types of books immediately appeared in the bookstore.

There are all sorts of books, such as "108 Essential Time Travel Skills for Time Travelers" and "Ancient Methods for Making Mosquito Coils".

However, these books are all in dark gray and cannot be purchased yet.

With a "nothing to lose" mentality, Jiang Wanwan directly clicked on the book "108 Essential Time Travel Skills for Time Travelers".

!!

Wow! Books can actually be opened and read!

In other words, even if she doesn't buy books, she can still read them. It's just not as convenient; she can't take them out, she can only read them in the online store!

In this way, wouldn't the books in the mall become a giant mobile library?

She couldn't hide her joy; could this be considered a bug in the mall?

When Jiang Jialin saw his daughter eating noodles with such joy, as if she had found a treasure, his heart melted. He secretly thought that his daughter was a content and happy girl, unlike Su Wan'er who was greedy.

Jiang Wanwan had no idea what her cheap father was thinking. Following the table of contents, she quickly jumped to "The Process and Method of Making Mosquito Coils Using Traditional Methods" and browsed through it.

The method is very simple; it's something anyone can do.

The remaining issue is preparing the materials.

Jiang Wanwan quickly ate the noodles in her bowl. She put down her chopsticks and said to Jiang Jialin, "Dad, I still need to go buy some things. Please wait for me here."

After saying that, without waiting for her adoptive father to react, she took off running.

Jiang Jialin was frantic as he watched his daughter disappear in an instant.

He wanted to chase after her, but he couldn't see where his daughter had gone, and he also had a lot of things to do, so he couldn't leave for the time being.

Jiang Wanwan hid in a shop, peeked out, and breathed a sigh of relief when she saw that her adoptive father hadn't chased after her.

She came out to buy some materials for making mosquito coils.

She'll be doing something behind the scenes soon, so her cheap dad naturally can't come along.

Jiang Wanwan was walking down the street when she saw a stall selling bamboo baskets and woven bamboo crafts. So, she spent a few coins to buy a bamboo basket.

I need to use it to memorize something later.

She went to the pharmacy and inquired about the prices of dried mint leaves and dried mugwort leaves.

Peppermint leaves at the pharmacy weren't expensive, only two coins a pound. Dried mugwort leaves were even cheaper, costing only one coin a pound.

She compared the prices at the pharmacy and the mall, and decisively chose to buy from the pharmacy because it was cheaper.

So, Jiang Wanwan immediately bought ten catties of dried mint leaves and ten catties of dried mugwort leaves.

Afterwards, she went to a spice shop and bought a pound of elm wood mortar and a pound of rosin powder.

In ancient times, spices were quite expensive. Elm wood mortar cost 25 copper coins per pound, while rosin powder cost 30 copper coins per pound.

Elm wood adhesive powder and rosin powder are even cheaper in the mall, with elm wood adhesive powder costing forty yuan for five jin and rosin powder costing twenty-one yuan for five jin.

After comparing prices, Jiang Wanwan only bought one pound of each item at the incense shop, so that she could buy from the mall through legitimate channels.

She put the materials she bought into her basket and then chose a less crowded alleyway to walk down.

As she walked, she opened the online store and bought ten kilograms each of rosin powder and elm wood adhesive powder.
