"Thank you boss, thank you boss."

The store owner is naturally happy.

After collecting the money, he issued a receipt to Du Ruhui.

When it's time to pick it up, come over with the receipt and you can take the mattress away.

"By the way, boss, what does the inside of your mattress look like?"

Du Ruhui accepted the receipt and asked curiously.

Although Fang Yuan said he was putting the spring in, he was still curious about how to put it in and what it looked like.

Du Ruhui was very curious about the bed that allowed him to sleep soundly, and wanted to understand its structure.

"I don't know about this. I'm only responsible for selling, not manufacturing."

"If the boss wants to know more, he can ask the people at the Mohist Research Institute. They invented the mattress."

The shop owner thought of being polite.

After accepting six copper coins, Du Ruhui is now his grandfather.

"Is it the Mohist Research Institute again?"

"Does the boss know what the Mohist Research Institute does?"

Du Ruhui frowned and said in a deep voice.

The same was true for Li Shimin, who became more and more curious about the Mohist Research Institute.

"I don't know much, I just know that I invented things."

"Ice cubes, mattresses, cement roads, toilets, etc. were all invented by the Mohist Research Institute."

"Oh, by the way, ask the county magistrate. The magistrate knows best. The Mohist Research Institute was established by the magistrate."

The shop owner shook his head and said embarrassedly.

Then he saw Fang Yuan sitting on the other side drinking tea, and his eyes immediately lit up.

Li Shimin and Du Ruhui looked at each other, then turned to look at Fang Yuan who was drinking tea.

At this moment, the two people's understanding of Fang Yuan deepened, and they were full of curiosity about the Mohist Research Institute.

Fang Yuan seemed to feel someone looking at him. He looked in the direction of the feeling and saw Li Shimin and Du Ruhui looking over.

"Are you sure?"

Li Shimin nodded at the right time.

He and Du Ruhui walked towards Fang Yuan one after another.

"Then let's go."

Fang Yuan put the teacup back and stood up.

"The county magistrate goes slowly, the two distinguished guests go slowly, welcome to visit next time."

The shop owner sent the three people to the door, waved and bowed to Fang Yuan and the others.

"Fang Xianzun, I heard that ice cubes, mattresses, cement roads, and toilets were all invented by the Mohist Research Institute."

"After visiting South Street, I wonder if you can take us to visit the Mohist Research Institute?"

Li Shimin asked.

Du Ruhui on the side also watched.

Both of them want to see the Mohist Research Institute.
