90. She hides many secrets

"Sister Haitang, let's go home." Wintersweet saw that it was almost done. It was getting very late now.

"Sister Haitang... Dahonghua, when did you become Sister Haitang?" Mr. Zhang stared at Bai Haitang curiously, always feeling that this girl had many secrets hidden in her body.

Lamei realized that she had made a mistake and quickly covered her mouth.

"I never said my name is Honghua, you always call me that, Mr. Zhang." Bai Haitang said.

"What, you pointed out the red flowers to me on the mountain, and I was deceived by you at that time." Mr. Zhang shook his head helplessly.

"I'm referring to a crabapple tree, but Mr. Zhang doesn't look at the tree, he only has red flowers in his eyes..." Bai Haitang said with a smile. This left Mr. Zhang speechless, who let himself be blinded by a leaf.

"Well, whether it's big red flowers or crabapples, come to Zhang Mansion to find me as soon as possible. Everyone in the county will know where I am. And Miss Wintersweet, I will definitely return your car next time we meet." Mr. Zhang smiled.

"I will arrive before the birthday banquet." Bai Haitang nodded.

Even if this is a simple saying goodbye.

Bai Haitang and Lamei were finally able to go home. After walking for a while, they saw the two people in front of them approaching, it was Tian Ertong and Lamei brother.

When the two families saw that the two girls hadn't come back yet, they became anxious and asked them to come out to greet them. As expected, they didn't go far before they met.

"Mom said don't come back so late in the future. Everyone is sleeping in the dark. It's scary for you two girls to walk at night. You are not afraid of meeting bad people. People in the city are not as simple and honest as us in the village." Tian Er agreed.

A few seconds later.

But hearing this scolding, Bai Haitang and Wintersweet felt relieved and happy.

Only family members will really worry about themselves.

Seeing that Sister Haitang didn't say anything, Lamei also told what happened that didn't happen today. Since it had been solved, telling it would only make the family worry in vain.

And maybe they won’t be allowed to go to the county seat.

Back in the village, Lamei was satisfied with the rouge gouache she bought in the county and went back to the house to appreciate it carefully. Alas, it was just a pity that half of the fat chicken was there, otherwise it would be great to take it out as a midnight snack now.

Bai Haitang saw that her daughter was fine and was sleeping soundly while chewing her little finger. She didn't want to sleep, so she lay beside her daughter and looked at her like this, as if she was happy.

"Baby Tian Tian, ​​it won't be long before you can see your daddy. Aren't you looking forward to it? In fact, mom hasn't seen it either. She's looking forward to it just like you..." Bai Haitang patted Tian Tian and hummed softly.

.

The next day, Bai Haitang will start studying fireworks.

Fireworks are made of black powder plus some metal salts and other ingredients. The color effects also require the addition of some chemicals, which are found in most mines.

Its color is what is called flame reaction in chemistry. When different metal mixed compounds burn, they will produce different colors.

For example, mixing sodium will produce yellow, lithium will produce purple, potassium will be purple, copper will be green, barium will be yellow-green, strontium will be magenta, and calcium will be brick red. These colors are commonly used in the fireworks production process and are also visually matched.

The effect is relatively good.

Since it is a birthday banquet, Bai Haitang naturally uses warm colors, bright red and purple, so that it can have the grandeur of a hundred flowers blooming. This birthday gift is a favor to Mr. Zhang, and this favor will not be given in vain. There will always be more in the future.

When I return.

Bai Haitang also believes that among all the people wishing birthdays, she is the only one who can give such a gift.
