Although Tong Cheng'er was shocked, she was somewhat prepared, so the shock passed quickly.

Others are different. Although they know they can make money, they are not prepared for how much they can make.

Yinzhen gave them a number, and everyone could no longer ignore it.

When the Crown Prince took out the five thousand taels, he was only thinking about participating and not how much he could earn from the investment. But then he heard the amount that Yinzhen mentioned.

Even the well-informed Crown Prince was somewhat bewildered and completely stunned.

After a long while, he finally said, "Fourth brother, are you telling the truth?"

Yinzhen: "Would I lie to my second brother, the Crown Prince?"

The Crown Prince laughed: "Very well! I'll remember this for you."

He was in dire need of money recently, and Suo'etu, knowing he was short of funds, would send him money from time to time. Although the Crown Prince accepted the money, he was not at ease with it.

After all, he didn't delve into how Suo'etu got his money, but he knew that the source was probably not entirely clean.

Now that I have income, I can take less money from Suo'etu in the future. Not only will it make things easier for me, but it will also make Suo'etu more restrained.

He used to be controlled by him and couldn't say much, but now he can say a few more words.

This time, the Crown Prince was truly grateful to Yinzhen.

There's also the pencil issue.

"Ninth Brother did a great job with the pencil. I used to think he didn't care much about his studies, but I didn't expect him to be so talented in this area. Father Emperor is so good at choosing people."

Kangxi did not mention that Yinzhen had asked him to go into business, so the Crown Prince only thought that his father had a discerning eye and had seen Yinzhen's talent at a glance, and had made a special arrangement for it.

As August arrived, Beijing became incredibly lively, with pencils and sofas instantly becoming the hottest topics in the city, and these two topics subsequently spread to the surrounding areas.

It began to set off a trend in the Qing Dynasty.

If we're talking about who benefited the most, it has to be Tong Cheng'er, who stayed in the backyard of the Fourth Prince's mansion. She got everything from pencils to sofas.

We originally planned to settle accounts every six months, but now that we've made so much money, we've decided to settle accounts every month.

Tong Cheng'er received 100,000 taels of silver as her share of the first month's earnings from the pencil case.

The sofa yielded a slightly higher profit than the pencil, amounting to 150,000 taels of silver, not even including the one-twentieth interest that Yinzhen himself received!

Tong Cheng'er originally thought she had too much money and wanted to spend more.

Despite his extravagant spending habits, he ended up with more money than he intended.

Tong Cheng'er wasn't worried about having too much money, but she couldn't just leave it all lying around.

Just as Tong Cheng'er was thinking about how to spend the money, Yinzhen brought some news.

"What did you say? A tour of Mongolia?!"

Yinzhen nodded: "That's right, it's a tour of Mongolia. This tour of Mongolia was decided on the spot by Father Emperor."

It wasn't in my dream either.

Tong Cheng'er looked at the weather outside: "Running outside in this sweltering heat, isn't Father Emperor worried that the accompanying guards won't be able to stand it?"

Yinzhen was able to guess his father's thoughts.

The sudden appearance of pencils and sofas brought a huge sum of money to the national treasury. Now that the treasury is full, the Dzungar rebellion has not been completely quelled, and Mongolia still needs to keep a close watch on things.

There was also the idea of ​​governing Mongolia through economic means, which the young princess had mentioned. His father, the emperor, saw the profits from pencils and sofas and felt that Mongolia could be governed through economic means.

This trip to Mongolia may seem somewhat sudden, but it is actually quite reasonable.

As for the weather, it will pass eventually if we just wait it out.

He said he was going to Mongolia, but he wouldn't set off immediately; Kangxi gave him five days to prepare.

It was Tong Cheng'er's first time traveling so far, and she really didn't know what to bring. Seeing her like this, Yinzhen took over the matter and told her not to worry about it.

Then Tong Cheng'er really stopped asking about it.

Three days after Tong Cheng'er learned that she was going to Mongolia, a coachman named Dong Li requested an audience.

Logically speaking, he shouldn't be able to meet Tong Cheng'er, but Dong Li has a good uncle, who is Dong Cheng's nephew.

This nephew was Dong Cheng's younger brother's only child, and since Dong Li's parents had already passed away, Dong Cheng took his nephew in and found him a job as a coachman in the mansion.

He was quite clever and drove the carriage steadily, and gradually he established himself.

In private, he also learned the craft from Dong Cheng.

Then he came into contact with springs. Because he was often in contact with carriages, he couldn't help but start to let his thoughts wander when he looked at springs.

“Madam, Dong Cheng from the Qiqiao Courtyard has arrived with his nephew, saying they have something to discuss with you.”

Upon hearing that it was the Qiqiao Academy, Tong Cheng'er said, "Let them in."

"Yes, Madam."

A short while later, Dong Cheng brought Dong Li over.

Dong Cheng and Dong Li: "This servant greets the Princess Consort."

Tong Cheng'er smiled and said, "Get up quickly."

"Xie Fujin".

Tong Cheng'er asked directly, "What brings you here today?"

Dong Cheng said, "This servant brought my nephew here today because he has recently been working on something, and I wanted to show it to the Fujin (wife) to see if it is useful."

Tong Cheng'er was pleasantly surprised to hear this. The pencil and the sofa were both her ideas. Now that someone could make things on their own, it was a huge step forward.

She looked at Dong Li and asked, "What is it?"

Dong Li spoke somewhat nervously: "This servant combined the springs with the carriage and discovered that this could reduce the carriage's bumps."

Tong Cheng'er's eyes lit up when she heard this.

Shock absorption!

She often rode in carriages. In the capital, the roads were relatively good, so the ride wasn't too bumpy. However, when she went to temples outside the city to offer incense, the roads there were much worse than those in the capital, and the ride was very bumpy.

She wasn't particularly happy about going to Mongolia this time. Firstly, the weather was hot, and secondly, she didn't want to sit in a horse-drawn carriage for a long time.

"Are you telling the truth?"

Dong Li was startled by Tong Cheng'er, then nodded: "What this servant said is true."

Tong Cheng'er said, "Alright, are there any carriages with springs installed now?"

Dong Li nodded again: "Yes."

Tong Cheng'er said with a smile, "Alright, then you should get ready. Make a slightly uneven road in the manor so I can personally test the shock absorption of the carriage you made and see if it's really as good as you say."

Upon hearing this, Dong Li excitedly replied, "Yes, this servant will go and prepare immediately."

Dong Li understood that this meant that as long as the carriage had shock absorption, there would definitely be a reward, and possibly more. The most important thing was that it could catch the eye of the Fujin (principal wife).

What Dong Li could understand, Dong Cheng naturally understood as well.

As the eldest uncle, Dong Cheng naturally hoped that his younger brother's children would fare well.

He knew the effectiveness of the carriage; otherwise, he wouldn't have dared to bring people to Yaocheng Courtyard. So, after hearing this, he went out with his nephew to make preparations.

Uneven roads are easy to deal with; the Fourth Prince's residence has a small training ground where you can just put some small stones.

"Madam, Dong Cheng has reported that everything is ready."

Tong Cheng'er nodded: "Alright, now that we're ready, let's go!"

Tong Cheng'er personally tested it, and the effect was self-evident; it was naturally excellent.
