Seeing that Lin Zao's complexion was indeed normal, Butler Wu left with peace of mind.

The storeroom in the outer courtyard of the general's mansion usually kept some commonly used medicines, including saltpeter.

Butler Wu brought over a basin of water for Lin Zao.

Lin Zao took out a larger wooden bucket, put a smaller bucket inside it, and filled both with water.

Then the saltpeter was put into the outer bucket.

Ice made directly from saltpeter is not edible and has a slight toxicity.

That's why a bottled water container was placed inside separately.

After the saltpeter melts, the water temperature drops considerably, but it's not yet at the point of turning into ice. So, it needs to be wrapped up and placed in a cool place for two days, at which point it will turn into ice.

Lin Zao took the bucket directly to the cellar, which was originally dug specifically to store ice.

Unfortunately, they were not the owners of this mansion last year, so naturally they did not store ice.

On the third day, Tang Jian returned, and Lin Zao took him to the cellar to witness the miracle together.

When the two arrived at the cellar, they saw a wooden barrel that was wrapped tightly. Lin Zao immediately unwrapped the outer wrappings, revealing the barrel inside.

A puff of white steam rose from the outside of the bucket, and there was a layer of frost on the outside.

"It's done!"

Lin Zao turned around and looked at Tang Jian with a smile on her face.

Tang Jian took a few steps forward and, sure enough, saw the ice cubes in the wooden bucket. A look of surprise flashed in his eyes, and he turned to look at Lin Zao and said:

"My wife is amazing!"

Lin Zao felt a little embarrassed by his direct gaze and praising tone.

"Everyone in my area knows how to do this, it's not that I'm better."

Tang Jian looked at her intently:

"To me, you are the most amazing. Without the things you brought, we might never have known about these amazing things in our lives. This is all thanks to you, and it is indelible."

Seeing Tang Jian suddenly become so serious, Lin Zao suppressed her shyness and slowly revealed a radiant smile to him.

She didn't argue with him anymore, and happily said, "Let's get some ice and take it to Mother. I'll also make a chilled dessert to cool you down."

Tang Jian looked at Lin Zao indulgently, a happy smile on his face, "Okay, I'll hold it for you."

That day, after Tiger Head and Ya Ya returned from the Prince's Mansion, they were pleasantly surprised to find that there was ice in their home, and even ice bowls to eat!

The two children jumped up happily. Children have a lot of energy and are most afraid of the heat, so they haven't been having a good time lately.

Taking a bite of chilled fruit is so refreshing; it instantly cools you down.

These fruits were all taken out of Lin Zao's space; there are very few fruits for sale in Ganzhou now.

She didn't give any to outsiders; it was all just for her family, so she wasn't worried about arousing suspicion.

Tiger Head finished his meal in a few bites and wiped his mouth, saying, "It's so delicious! Mother, can I take it to the Prince's Mansion for Brother Xiaobao to eat tomorrow?"

Despite being the most powerful mansion in the entire Ganzhou, the Chengwang Mansion now faces difficulties even in obtaining ice, with only a small basin being used when the Chengwang is conducting official business.

Let alone using it for food.

Lin Zao knew the children got along well, so she didn't refuse, however:

"These ice bowls are not easy to store. They might melt by the time you take them to the Prince's Mansion. I've written down the method for making ice on a piece of paper. Take it to the Prince's Mansion tomorrow and have your brother Xiaobao give it to the Prince. In a couple of days, you'll be able to enjoy ice bowls at the Prince's Mansion."

Tiger Head's eyes lit up. "Really? That's wonderful! Thank you, Mother!"
