If Li Xiu'e followed his advice today and really wanted to seek justice, she would inevitably be regarded by Yuan Wenxuan as a maid who didn't know what to do or what to do.

This is not Yuan Wenxuan's fault, it can only be said to be caused by the overall pattern of the great era. People in high positions regard the grassroots as ants, and the status hierarchy is so strict that it is difficult to attach them.

Just like Li Xiu'e, who can only tell the whole story fluently when she is kneeling on the ground.

Su Yin suddenly stood up, yawned, stretched hard, and said, "It's getting late, I'm going to bed."

Yuan Wenxuan was stunned immediately, "You called me here just to tell me that you are sleepy?"

"When did I call you over?" Su Yin frowned and looked at him.

"You obviously..." Yuan Wenxuan followed Su Yin's example and tilted his chin.

Su Yin grinned playfully, "It's just a cramp in my neck. You have a noble body, so don't waste your time here with me. Go back and go to bed quickly?"

Yuan Wenxuan was furious, snorted and walked away.

"I'll take you around Qingbei City tomorrow." Seeing him going out, Su Yin called out.

A head popped out of the door and asked, "Is there anything interesting in Qingbei City?"

Su Yinfei nodded.

After the door was closed, Li Xiu'e got up from the ground and said, "If the young master is fine, I will leave."

Su Yin nodded, looked at her back and suddenly asked, "If you were allowed to leave the Su Mansion and no longer be a slave, would you be willing?"

Li Xiu'e was startled, looked back at Su Yin, and said with a pale face, "Young Master wants to expel the slaves from Su Mansion?"

Su Yin pondered for a moment, "That's right, but I want you to help me with something."

Li Xiu'e was stunned for a moment, and Zhang Laishun on the side couldn't help but ask, "Yin Zi, what can't you leave to me? What do you want a woman to do?"

Su Yin ignored him and looked at Li Xiu'e.

Li Xiu'e bit her lip and said, "Young Master is Xiu'e's savior. If it is something that Young Master has told you, Xiu'e will do her best."

Su Yin smiled, beaming.

Early the next morning, as soon as Zhang Laishun entered Su Yin's yard, he heard a few tinkling clangs inside, coming from behind the flower bed.

Zhang Laishun went over to take a look and saw Su Yin standing behind the flower bed, seemingly tinkering with a stove. This black stove was used for heating in winter. What was she doing with this thing so early in the morning?

"Do you still have any burning stones for heating in the winter? Find me some." Su Yin seemed to know that the person standing behind him was Zhang Laishun without even looking back.

Zhang Laishun was stunned, "What are you going to do?"

"I'll show you something new to do." Su Yin grinned, revealing two bright little tiger teeth.

Zhang Laishun left the yard with a head full of questions.

The burning stone that Su Yin mentioned was actually charcoal. Based on Su Ziyin's memory and recent observations, Su Yin discovered that charcoal is used for heating in winter, not coal. Of course, charcoal is not as durable as coal.

Moreover, only a limited number of people can use this method for heating, because the price of burning stone is relatively high, not to mention that small households do not have heating facilities.

For example, in the Su Mansion, the ladies' rooms have fireplaces with exhaust ducts, which can release carbon dioxide to avoid indoor poisoning and make the indoors warm as spring in winter. It seems that the wisdom of the ancients cannot be underestimated.
