บท 248: Do him a favor

After the Wu family's matter came to an end, the county resumed its peaceful days.

Mo Qingling had the wooden box sent to the capital on horseback.

As for how to deal with it, it was none of his business.

Then, he publicly disclosed that he found the iron mine and hired people to open it.

He still had the iron-making formula given by the emperor, and the Ministry of Works had sent two people to assist him.

Soon, a workshop for ironmaking was built.

Shi Qingluo was wearing a sweater and a furry cloak that her young husband had specially sent people to the prefecture capital to make, but she still felt cold.

She realized that they were all using braziers.

If they used ordinary carbon, the fireworks would be big and choking.

They had to use silver thread carbon to avoid such a problem, but a brazier was also cold.

It would be too expensive to put in more braziers.
