So fragrant

Xiao Hanzheng was also happy that Mo Qingling praised his little wife.

"My wife often has fantastic ideas, which I think are quite good."

Mo Qingling nodded. "Indeed."

He added, "The formula for making ice has been sent over. Our county will receive the reward in a few days' time."

The imperial palace was making ice every day to cool down the heat. 

Many families in the capital had also bought saltpetre to make ice.

Mo Qingling had also heard that many restaurants in the capital were using ice to make cold drinks. 

The cold green bean soup and sour plum soup were very popular.

In addition, Shi Qingluo's sharing on making herbal tea and ice popsicles had also spread to the capital. There were often hawkers selling popsicles on the streets.

Then, he changed the topic. "The reward is gold."

Xiao Hanzheng was not surprised at all.
