Who understands? He traveled through time with a high-spec spatial ability.

Chun Ya was visibly taken aback upon hearing this. But she quickly nodded: "Chun Ya is willing! These days at the academy have been the happiest time of my life. I want to find a good way out for myself, even if it means becoming a servant for my sister, I want to be the most learned and useful servant."

Qiao Jingjing was amused by her words, "Don't worry. I'll take care of everything."

After the event, Qiao Jingjing specifically sought out Chun Ya's older brother.

She told him bluntly that she had already signed a contract of servitude with Chun Ya, but the girl had now gone back on her word. Therefore, according to the contract, Chun Ya was required to compensate her for her losses, totaling ten taels of silver.

Qiao Jingjing emphasized that since he was Chun Ya's only relative, he should naturally pay for it.

Chun Ya's older brother was a greedy man, so he was naturally unwilling to compensate for the losses. He grumbled reluctantly, complaining about how this had fallen on his shoulders.

Seeing this, Qiao Jingjing sneered, took out a contract of servitude from her bosom, and then unfolded it in front of everyone.

She pointed to the words on the indenture and said loudly, "It's written clearly in black and white on this indenture that your sister Chun Ya has already sold herself to me. What else do you have to say?"

Upon hearing this, Chun Ya's brother's face turned deathly pale. He stared wide-eyed at the contract of sale, cold sweat beading on his forehead. He never expected that Qiao Jingjing would have such evidence.

Seeing that he didn't speak, Qiao Jingjing continued, "Do you know that daring to deceive the county magistrate is a serious crime that can land you in jail!"

These words struck Chun Ya's brother like a bolt from the blue, making him tremble all over. He looked at Qiao Jingjing in horror, his legs went weak, and he almost knelt down.

"County...County Princess, I know I was wrong! I really didn't know you were me! Please spare my life!" Chun Ya's brother begged for mercy while quickly distancing himself from Chun Ya, "This Chun Ya has nothing to do with me, I don't know her at all!"

Chun Ya stood to the side, feeling a sharp pain in her heart upon hearing her brother's words. Her eyes widened in disbelief as she stared at him, tears welling up in her eyes.

Chun Ya didn't cry out loud. Suppressing her inner pain, she knelt down before Qiao Jingjing with a thud and kowtowed deeply. She never imagined that her sister, who usually chatted and laughed with them, was actually a county princess.

"Your Highness, I have no way to repay your great kindness. From now on, I will study hard and repay your kindness in the future." Chun Ya's voice was a little choked up, but it was unusually firm.

Seeing this, Qiao Jingjing quickly stepped forward to help Chun Ya up and comforted her, "Get up, get up. I always hoped that you could all learn something and become outstanding doctors in the future."

Lu Yuan benefited the most from this event, and he and Guo Pingting had endless topics to discuss.

However, he did not forget his mission and set off for Pengcheng on the third day after the event ended.

The Sihai Chamber of Commerce was established in Pengcheng at an extremely rapid pace. Trade between the Yan and Liang states officially began.

After the establishment of the Sihai Chamber of Commerce, the flow of various goods became frequent. Goods in the general store, such as salt, soap, soybean oil, and health wine, were in high demand and short supply.

The wool purchased from the border of Dayan was used by Qiao Jingjing to set up a textile factory in the area with Lu Yuan. Through processing, the wool was spun into yarn, which was then transformed into wool sweaters and wool pants.

A large portion of the mutton was transported by caravans to the capital of Liang. The booming popularity of hot pot and barbecue significantly boosted the supply of mutton.

After tasting the hot pot, Liu Bian, Zhao Kun, and others once again used their business acumen to their advantage, opening hot pot branches in their own business territory.

Qiao Jingjing tacitly approved of all of this, after all, they had never hesitated to donate money and food, and she was willing to cooperate with them.

Having tasted success from selling wool and mutton, the people of Yan quickly developed animal husbandry on a large scale.

Anyway, every part of a sheep is valuable; the mutton can be sold, and the wool can be sold, so they can't lose money no matter what. Moreover, Boss Lu, who is in charge of the trade this time, is extremely trustworthy and will never let them suffer losses.

With the increasing prosperity of trade, Qiao Jingjing had a new idea. Since Liang Kingdom's porcelain was exceptionally exquisite, she planned to introduce porcelain trade into the trade between the two countries.

She instructed Lu Yuan to find high-quality porcelain suppliers in Liang Kingdom, and at the same time, to establish a dedicated porcelain sales area in Great Yan.

"Let's try recruiting again, see if we can find some experienced craftsmen, and give it a shot in the tile industry."

Lu Yuan nodded: "Okay."

Looking at the increasingly composed Lu Yuan, Qiao Jingjing sincerely sighed, "It's so good to have a friend you can trust wholeheartedly."

He's now acting with perfect composure and has found a girl he likes. If Madam Feng knew, she'd be overjoyed.

Qiao Jingjing glanced at the calendar on her phone; the coronation ceremony was in two days.

It's time for her and Tantai Zhou to go back.
