Looking at Lin Daiyu's slender back gradually moving away, Jia Chen's heart seemed to be kissed by Daiyu, and an indescribable warm feeling came to his heart, rising with a warm desire to care.

Jia Chen secretly made up his mind in his heart:

I want to take care of Lin Daiyu, take care of her for the rest of her life, if there is an afterlife, even if I search the ends of the earth, I must find her, stay with her for a long time, and never be separated.

It wasn't until Lin Daiyu's petite figure disappeared into a sea of hibiscus forests that Jia Chen withdrew his gaze and walked into Rongxi Hall.

Jia Zheng was sitting on the main seat, holding a tea cup, chatting with the guests.

After getting along these days, Jia Chen somewhat understands Jia Zheng, a pedantic and old-fashioned nerd.

He is willing to let so many Qing guests come to Rongguo Mansion to eat and drink, in fact, because he is not familiar with popular affairs and is not good at socializing, and there are not many high-ranking officials and nobles who are willing to associate with him.

In order to relieve his loneliness, he had to pay to feed a group of Qingke and chat with him to relieve his boredom.

When he saw Jia Chen Shi Ran walking in, Jia Zheng suddenly smiled all over his face.

Jia Chen is both civil and military, outstanding in poetry, can write books and speak, and has a bright future, which makes Jia Zheng feel honored and has a lot of face in front of a group of Qing guests.

"Chen'er is here, sit down and have a cup of tea." Jia Zheng took the initiative to say hello enthusiastically.

If another son or nephew came to visit, he would definitely hold the shelf and wait for the other party to finish saluting him before he opened his mouth to respond.

Only Jia Chen is an exception, who made Jia Chen so outstanding?

Jia Zheng likes him so much that he really can't wait to accept him as his godson, but because of etiquette, it's a bit unseemly to do so, so he has to give up.

Jia Chen saw that Jia Zheng smiled a little too exaggeratedly, and thought that he had some habit of breaking his sleeves, after all, Jia Baoyu was a double plug, and it was difficult for his father to say whether he had these weird hobbies, it seemed that he would have to keep a distance from this political master in the future.

"Little nephew, please say hello to the second uncle!" Retracting his thoughts, Jia Chen bowed to Jia Zheng without humility or arrogance.

Jia Zheng smiled:

"You've always been busy with schoolwork, so why are you here today?"

Jia Chen looked at the group of Qingke sitting on both sides of the column, and replied with a smile:

"But there are important matters to discuss, but I don't know if it will delay the time of the Qing guests."

The Qingke are all good at observing words and feelings, and they immediately got up and said goodbye.

Jia Zheng doesn't have the slightest hint of innocence, and the combined weight of these Qingkes is not worth a finger of Jia Chen.

When everyone dispersed, Jia Chen smiled:

"I came to visit my second uncle today because I have a chance to make a fortune and want to share it with Rongguo Mansion."

Jia Zheng's eyes lit up, Jia Chen wrote a book of "Disciple Rules", and also cooperated with Rongning Erfu to engrave and sell, which can be regarded as opening up a source of wealth for Rongguofu, although it has just been sold for two months, it only brings a few hundred taels of income to Rongguofu.

But this is a long-term investment that can be trickled down the long term, and with sales climbing month by month, the second month nearly doubling from the first, and it is hard to imagine how much revenue will rise in the future.

Unexpectedly, Jia Chen had other ways to make money and wanted to cooperate with Rong Guofu.

This kid is simply the God of Wealth!

His own family knows his own affairs, although Jia Zheng does not ask about the world, but as a family member of the Rong Mansion designated by Jia's mother, he naturally knows that the inner bag of the Rong Mansion is almost exhausted.

Although the income of several hundred taels of "Disciple Gui" in the past two months is tantamount to a drop in the bucket for the huge Rongguo Mansion, it is no less than a timely rain.

If Jia Chen helps the Rong Mansion open up a new source of wealth, then maybe the Rong Mansion will be able to balance its income and expenditure, and even turn losses into profits.

Thinking of this, Jia Zheng asked impatiently: "Virtuous nephew, please come and listen." ”

Jia Chen smiled indifferently and said:

"Second uncle, do you know what the women of Da Zhou usually use to make up?"

Jia Zheng was slightly stunned, and immediately guessed that Jia Chen's way of making money should be related to this, so he smiled:

"Although I am not a woman, I have a wife and two concubines, and I see that they usually wear makeup and use rouge gouache."

Jia Chen smiled:

"I'm going to use a brand new cosmetic product called alabaster to completely replace all the rouge gouache in Da Zhou."

Jia Zheng gasped, good guy, why are you so angry?

"Chen'er, although you are talented, you can't speak wildly and boast about yourself." Jia Zheng persuaded bitterly.

Jia Chen smiled and said:

"Second uncle, I'm not lying to me, this replacement process is not achieved overnight, but after many years, it will definitely be realized."

Jia Zheng asked suspiciously:

"And what are the ingredients you are talking about made of this alabaster you are talking about? How is it better than the previous rouge gouache? ”

Jia Chen smiled:

"It's actually very simple, you only need to use four ingredients: beeswax, flower juice, milk and glycerin."

Jia Zheng frowned and asked:

"I've heard of the first three things you said, but what is this glycerin?"

Jia Chen said:

"Glycerin is a thick, colorless, sweet-tasting sauce."

In fact, Jia Chen wanted to produce alabaster to make money, but it was only one of the purposes, and there was another hidden purpose, which he did not say, that is, glycerin was one of the ingredients of yellow powder.

In the Great Zhou, black powder has begun to be widely used in the military, the Ministry of Industry has set up two bureaus of military warfare and ordnance, responsible for building firearms and ordnance, but although there are many varieties of cannons, the technology is very backward, called Mantianxing artillery.

There are three types of shells used in the Starry Artillery: shotguns, solid shells, and flowering shells, but none of them are very powerful.

The Great Zhou also introduced the Western Franc cannon and the Hongyi cannon, which were more powerful, but because the shells were also made of black powder, the lethality was still limited.

This year is the seventh year of Chongrui of the Great Zhou, which is equivalent to the first year of Chongzhen of the Ming Dynasty in the previous life.

At this time, the Later Jin established by the Jurchen Nurhachi in the Northeast continued to grow, repeatedly violating the frontier, and the Great Zhou did not have effective weapons to restrain the Iron Cavalry of the Eight Banners of the Later Jin, and mainly relied on the starry artillery and Hongyi cannons and the Franc machine cannon for field battles and defending the city.

However, due to the power of the starry cannon is only equivalent to large fireworks, the range of the Franc cannon is short, the power is insufficient, the Hongyi cannon has a long range, but the rate of fire is too slow, and the three types of artillery can not continue to fire, as a result, when the Great Zhou army and the Eight Banners Iron Cavalry are engaged, there are more defeats and fewer victories, and the territory of the Great Zhou is constantly encroached upon by the Houjin.

Jia Chen knew that if this continued, Da Zhou would inevitably be like the Ming Dynasty in his previous life, swept by the Jurchen Eight Banners and swallowed the world.

Instead of sitting still, let's take a shot!

Jia Chen decided to use the reason for manufacturing and selling alabaster to produce glycerin on a large scale and secretly synthesize yellow powder.

Relying on the huge amount of money earned from writing books and selling alabaster, he recruited troops and horses, and hoarded ordnance, food and grass.

Under the nose of Jinyiwei, brazenly training a private army is tantamount to seeking a dead end, but Jia Chen has his own clever plan.

While training private troops who only obey their own orders, they also have to participate in the imperial examinations, and in the future, they must enlist in the army and take charge of military power.

At this time, Jia Zheng groaned and said with a smile:

"Chen'er is really a Qilin genius of my Jia family, I have lived for so many years, and I have never heard of such a rarity as glycerin, since Chen'er is full of confidence, I am also very confident in you, but I don't know how much silver it takes to make this alabaster? How much is Chen'er willing to pay? ”
