Although Madam Shen wanted to say something more, she was silenced by Shen Qianhe's sharp gaze.

She glared at Jiang Ling resentfully, rubbed her forehead, and stormed off, while Shen Congguang continued to cry and fuss beside her.

Shen Qianhe frowned and called Madam Shen back. When Madam Shen heard Shen Qianhe call her, she thought that Shen Qianhe was afraid of her, so she looked at Shen Qianhe triumphantly, wanting to make things difficult for him.

Unexpectedly, Shen Qianhe threw Shen Congguang into Madam Shen's arms and said coldly, "Take him away. Stop crying and whining. I'm not dead yet!"

After saying that, he turned and left without giving Madam Shen a chance to explain.

Madam Shen was furious when she saw this, and Shen Congguang's incessant crying only added fuel to the fire.

Madam Shen slapped Shen Congguang on the head and said fiercely, "What are you crying for! You good-for-nothing! Your father is right, I'm not dead yet!"

After saying that, she left Shen Congguang, who looked aggrieved, and went back to her room to sulk.

Inside the main hall, Shen Qianhe apologized to Jiang Ling with a beaming smile: "My son has not been properly disciplined, I'm so sorry to have made you laugh, my in-law!"

Jiang Ling glanced helplessly at Shen Qianhe. This wasn't a case of lax discipline; it was simply that he didn't want to discipline her at all. But then she thought, since the child wasn't hers anyway, it didn't matter.

He simply nodded and said to Shen Qianhe, "It's alright, it's alright. Children are just being mischievous at this age, it's fine for them to be a little naughty!"

Shen Qianhe was a shrewd person, and hearing Jiang Ling's words made him even more embarrassed. He awkwardly opened his mouth to change the subject, saying, "In-law, what brings you here today?"

Jiang Ling didn't speak at this moment, but gestured to Jiang Yaojie with her eyes. Jiang Yaojie nodded in understanding and took a bamboo tube in front of Shen Qianhe, saying, "My mother came here mainly to talk to Uncle Shen about our family's rare items."

"A rare find? My dear in-law, you are truly an extraordinary woman!" Upon hearing the words "rare find," Shen Qianhe's eyes immediately lit up, and he quickly inquired.

Jiang Yaojie calmly handed the bamboo tube to Shen Qianhe, opened the lid, and said to Shen Qianhe, "Uncle Shen, this is the shampoo my mother invented!"

"Shampoo?" Shen Qianhe frowned and muttered for a long time. Clearly, this was the first time he had ever heard this word.

He gently shook the bamboo tube, and the water inside emitted a faint minty scent, with some bubbles appearing in the water.

"My dear in-law, stop being so mysterious. What is it?" Shen Qianhe, who had an impatient temper, quickly pressed for an answer.

"I have a question for Mr. Shen: what do you usually use to wash your hair?" Jiang Ling asked instead of directly telling Shen Qianhe how to use the shampoo.

"Of course it's soap beans! These things are really expensive; just a little bit costs two taels of silver! Of course, this is for us. As for the servants, I usually give them some soap pods to mix with wood ash..."

At this point, Shen Qianhe suddenly paused, his gaze falling on the bamboo tube in his hand, looking at Jiang Ling with an incredulous expression.

After a long pause, he stammered, "This...could it be? It's like a soap bean?"

Jiang Ling nodded and added, "Yes, this is even better than soap beans, and it leaves a light fragrance after washing!"

Jiang Ling's words intrigued Shen Qianhe. He looked at the bamboo tube in his hand, then at Jiang Ling, and tentatively asked, "In-law, can I try out this thing now?"

"Of course." Jiang Ling had been waiting for Shen Qianhe to say this, and when she heard him ask, she quickly nodded in response.

Seeing this, Jiang Yaojie quickly explained to Shen Qianhe in detail how to use the shampoo.

After receiving Jiang Ling's permission, Shen Qianhe held the bamboo tube in her hands as if it were a precious treasure, and walked quickly outside, calling out the names of the servants as she went.

Before long, Shen Qianhe appeared in front of Jiang Ling and Jiang Yaojie with a smile on his face. It was easy to see from his smile that he was very satisfied with the shampoo.

As Jiang Ling expected, as soon as Shen Qianhe sat down, he gave Jiang Ling a thumbs up and exclaimed, "My dear in-law, you're really amazing! How did you come up with this? I've never felt so comfortable with my hair!"

"If this thing is mass-produced, will it be able to gain a foothold in the market?" Jiang Ling asked.

“Oh, my dear in-law, if you hadn’t said that, I would have really wanted to suggest it to you. This stuff is more durable than soap beans, and it works better too. The key is that I’ve never even seen this rare thing before!” Shen Qianhe paused deliberately as she said this.

He glanced at Jiang Ling and said, "My dear in-law, I have a favor to ask. If you really intend to produce in bulk, could I buy some wholesale from you? The porcelain business hasn't been doing particularly well these past few years, but I'm confident that your shampoo will sell out completely!"

“I can sell you the shampoo, but I can’t authorize it to you separately. Can you accept that?” Jiang Ling said, revealing her true thoughts.

In this era, many things are severely monopolized, and merchants can arbitrarily raise prices, completely disregarding the lives of ordinary people. Jiang Ling's original intention in developing shampoo was to make it available to everyone, and she did not want it to be monopolized.

"Yes, yes, that's easy to say. As long as you agree, my dear in-law, there's absolutely no problem!" Shen Qianhe nodded frantically.

Jiang Ling chatted with Shen Qianhe for a while longer, explaining that the shampoo was still in the research and development stage and the daily production volume was uncontrollable, so the two had not yet signed a sales contract.

But Jiang Ling still gave Shen Qianhe two more bottles for free.

As soon as they stepped out of the Shen family's house, Shen Qianhe glanced at Lu Bo's oxcart and frowned slightly. After hesitating for a moment, Jiang Ling said, "In-law, this oxcart is not as fast or comfortable as a horse-drawn carriage. I happen to have an extra horse-drawn carriage here, so why don't you use this from now on?"

As she spoke, Shen Qianhe called over a servant and whispered something to him. The servant nodded and turned to walk inside.

Before long, a carriage came galloping over from the alley next door. Jiang Ling glanced at the carriage. The carriage was covered with expensive and exquisite silk on all four sides. The windows, which were inlaid with gold and jewels, were covered by a light blue gauze curtain, making it impossible for people outside the carriage to see inside.

Jiang Ling looked at the magnificent carriage and wanted to shake her head to refuse, but Shen Qianhe said to Jiang Ling, "In-law, you have given me a way to make a fortune. A mere carriage is nothing."

"Besides, you'll definitely be traveling all over the country in the future, and you can't do without a carriage! So, I'll go in first!" Shen Qianhe turned and walked inside before Jiang Ling could refuse.

Seeing this, Jiang Ling couldn't refuse, so she had no choice but to bite the bullet and accept the carriage. The servant was a perceptive man, and he quickly bowed to Jiang Ling and Jiang Yaojie, saying, "Young master, let me teach you how to ride this carriage!"

Jiang Yaojie looked at Jiang Ling somewhat embarrassed. Jiang Ling nodded gently to Jiang Yaojie, and Jiang Yaojie could only bite the bullet and sit down next to the servant.

It must be said that Jiang Yaojie is quite talented at learning to drive a horse-drawn carriage; he mastered almost all the essentials of driving a carriage in just half an hour.

Lu Bo, who was sitting on the oxcart, walked up to Jiang Ling with a pale face and asked, "Jiang Shi, do you no longer need this oxcart of mine?"
