Ignoring his father's words, he took off the bundle from his back, took out two jars, and pushed them in front of Chen Xianming.

"Dad, look at this." He said, grabbing a handful of his greasy hair.

Chen Xianming was even more disgusted, but seeing his son looking at him with bright eyes, he couldn't bear to refuse his good intentions. He opened the jar and saw two jars of salt, one coarse and one fine.

He leaned closer to smell it, then looked up at his son. "Is it salt?"

Chen Gu nodded excitedly, "Dad, you should try it."

Chen Xianming had no idea what he was up to, but obediently tried both kinds of salt and couldn't help but give a thumbs up, "Good quality, where did you buy it?"

At this moment, the steward entered with a servant carrying a load of rice.

The servants put down the rice, and Chen Gu said to the steward, "Steward, have everyone leave."

The butler glanced at Chen Xianming, and seeing that he did not object, he waved for the servants to leave and closed the hall door before walking over to Chen Xianming's side.

Chen Gu stood up, picked up a small bundle of rice, and said, "Dad, watch carefully!"

As he spoke, he demonstrated how to thresh rice in front of the two men.

He took off two bundles of rice, and Chen Xianming couldn't sit still any longer. He stood up in astonishment, picked up a small bundle of rice, and started handling it himself.

"Where did this thing come from?" After trying it twice, Chen Xianming already knew the benefits of this thing.

Chen Gu sat in his chair, crossed his legs, and said smugly, "Dad, this thing is called a rice threshing machine. It was discovered in Longtan."

Chen Xianming immediately understood; his son had rushed back from Longtan. He then pointed to the two jars of salt on the table, "That salt?"

"It's from Longtan." Chen Gu stopped keeping him in suspense.

"There's a salt lake in Longtan. How come we didn't know about it before?"

He looked at the butler, who shook his head, indicating that he didn't know either.

Upon hearing that the two jars on the table contained salt, the butler hurriedly went over and dipped some in to test it. After testing it, a glint of light flashed in his cloudy eyes.

"Sir, this salt is all of the highest quality!"
