After the father of the subjugated country secretly read my heart, he became angry.

The weather hasn't gotten warmer yet, and Xiao Chuchu can't control her longing for modern and comfortable life.

Especially when she saw the people asking about borrowing money, many of whom were wearing old cotton-padded clothes, some of which were patched, she couldn't help but feel cold for them.

[Hey, Jingguo is still poor. Although the national strength has improved a lot recently, the country's ranking has risen three places. 】

[However, per capita wealth is still not sufficient, and very few people are pursuing a well-off life. 】

Xiao Chuchu felt even more distressed when she saw it with her own eyes.

Although she is wearing a down jacket, down jackets have not yet become popular in every household.

Xiao Chuchu felt more and more that in modern society, most people can wear warm clothes, eat well, and enjoy the life of electric heating and air conditioning. How happy they are and how hard it is to get.

[If Jingguo were richer, it would be great if everyone could have a thermos bottle, a thermos cup, a baby warmer, and a heater. 】

Xiao Chuchu sighed with emotion, and her heart could not help but fly away.

[emm It’s probably more difficult to use electricity for heating. The technology tree doesn’t even mention electricity at the moment. 】

[But I don’t know if I can work hard on thermos bottles and thermos cups. 】

Liu Wenchang, who was standing outside the carriage and about to talk to Liu Channiang inside, was startled.

Liu Channiang coughed slightly with a subtle expression and stopped the urge to speak.

[Ouch, grandpa is here~ I haven’t seen grandpa for a long time! 】

Xiao Chuchu was babbling, and she was in the nanny's arms in the car. She enthusiastically extended her short hand to the old man, asking for a hug.

[Is grandma okay? How is uncle? Has he found his aunt? My uncle is very old and he is still single. Hehe. 】

The more Liu Wenchang listened, the more complicated his expression became.

Is Little Princess worried about these marriage matters?

The reincarnation of a fairy is just extraordinary.

It was all her fault that her eldest uncle, a man who did not live up to expectations, had not yet gotten married, which made little Gege worried.

Liu Wenchang decided to go back and quickly urged the matchmaker to come to his door. Before, Liu had not obtained any honors in the leap year, had no official position, and no one wanted to get married, but now he has a salary from the Ministry of Industry.

"Dad, come up and talk. It's windy outside, so come up and warm yourself."

Liu Channiang spoke and asked someone to open the car curtains.

Liu Wenchang shook his head, "It's not a big deal. I won't come up. Your mother is still at home waiting for me to go back for dinner."

As he said that, he rubbed his hands and exhaled a breath of white air on the street, "You will feel less cold after walking around."

[Ouch, look at how frozen my grandpa was~ I wonder if we can make thermos cups and thermos flasks with today’s technology. 】

[If I can exchange it, I will quickly buy a set for my grandfather~]

Xiao Chuchu was suddenly struck by the word "cold" again, which brought her back to the wonderful idea of ​​technology changing life.

[In the past, thermos bottles, I remember, seemed to have two layers of inner and outer bladders in the bottle. 】

"!"

Liu Wenchang and Liu Channiang immediately pricked up their ears and stopped talking.

[The inside of the bottle is coated with mercury. 】

[I remember when I was a kid, I broke a thermos bottle and saw what it looked like inside...]

[If I remember correctly, this bottle bladder can prevent heat radiation to a certain extent and prevent heat from dissipating. 】

[There is a hollow space between the inner and outer bladders to prevent heat convection. 】

A bunch of weird words made Liu Wenchang and Liu Channiang feel like they were talking.

But Liu Wenchang quickly bit the tip of his tongue and forced himself to remember these strange words that he couldn't understand!

This must be an immortal article from the immortal world!

It's normal that he doesn't understand.

Forcibly write it down, maybe I can figure it out later.

Liu Wenchang gritted his teeth and memorized it silently.

[emmmm, but I only have this superficial theory. 】

Xiao Chuchu thought hard, and finally frowned.

[There is no way, I am a liberal arts student, my science knowledge is limited to high school physics, and I can make inventions through practical operations. 】

Damei, what does it mean?

Liu Wenchang had a headache hearing this.

What is a liberal arts student?

science?

Nowadays, the imperial examinations in Jingguo are divided into two categories: civil and military.

Could it be that the world of immortality is divided into arts and sciences?

His fairy-reincarnated granddaughter is in charge of literature in the fairy world?

Liu Wenchang tried hard to keep up with his granddaughter's murmurings, thinking that if Xiao Chuchu found out about Chongbao, he would probably laugh out loud in the middle of the night.

Xiao Chuchu thought irresponsibly, and finally ended with a sigh, "I wonder if our current scientific research talents in Jingguo, my uncle, can produce a thermos cup." 】

[Hey, I can’t count on this crappy system. I don’t get anything I want. Uncle is much more reliable than the system. 】

Liu Wenchang: "...!"

"Hey," he quickly glanced at his daughter Liu Channiang, "I heard that you are now acting as agent for the harem?"

"Then go back to the palace quickly. Dad, I'm going home too. I have to go back and look after the useless boss."

Liu Channiang's expression changed, and she quickly understood. She nodded and said, "Dad, next time you and your eldest brother enter the palace together, I will hold little Princess to see you."

After that, she asked Qiuli to take the charcoal rice paper from the carriage and hand it over.

[Hey, what did mother do for my grandfather’s pen and ink? 】

Xiao Chuchu was curious.

Liu Wenchang and Liu Channiang were silent at the same time.

But soon, after Liu Wenchang left the carriage for a while, he quickly walked to a deserted place and scrawled something with a pen.

‘Inner and outer guts’, ‘mercury’, ‘two layers of hollow’…

Then, he recited it silently to deepen his memory, then burned the paper with a fire, and walked home quickly.

"Boss," Liu Wenchang rushed into his eldest son Liu Runnian's house, opened the door, and shouted, "Something's coming!"

"You and me, I want a portable bottle that can keep hot water warm in winter. Hurry up and make it."

Liu Runnian: "...?"

He looked up from the pile of silk books piled high.

"What are you looking at? You don't know how to do it, right?" Liu Wenchang raised his head and raised his chest, "It's okay. I've already figured out how to do it. I'll teach you a few mantras."

"...Dad, you went out today to meet little Princess?"

"Don't talk nonsense, I'm not, I didn't..."

"What did Xiao Gege Xianyin say?"

"..."

*

The card game "Who is the Rich Man" is sold in full swing in major grocery stores in the capital.

The store is divided into two types: simple paper ones and hardcover wooden ones.

Simple packaging, with a wooden box, only costs half a tael.

Hardcover, five taels of silver.

All of a sudden, all the simple and hardcover items in the grocery store were snatched up by people who like new things.

"I heard that Lord Tobe plays this card game."

"More than that, this hardcover version of the brocade box says that this one is the same as the one worn by the emperor in the palace!"

"! The card game is too indecent. Haven't you heard that the great scholar Shen Mian Cifu wrote a poem about this board game. With a small table, he can travel all over the world and understand all principles, so the emperor gave it the name For board games.”

"!"

"The emperor and the Ministry of Household Affairs came up with the new loan strategy of the Qian Bank based on this board game of 'Big Rich Man', also known as 'Who has more money in Jingguo Qian Bank?'"

Students in the capital, literati, and even merchants who were curious about the new household policy and ordinary people with a little spare money couldn't wait to buy a simple or hardcover copy, and began to study it in teahouses or at home.

As soon as I researched it, I was hooked!

Moreover, he is deeply aware of the necessity of borrowing from money banks.

——If you want to buy land, start a business, or become a rich man, it’s great to ask a money bank for a loan!

In less than three days, the counters of the four Jingguo Money Banks in the capital were crowded with merchants who wanted to borrow money.

"Your Majesty, according to a rough estimate, our loan interest will be credited to tens of thousands of taels next month."

Jiang Li, the household secretary, couldn't close his mouth from ear to ear.

Xiao Yunzhou looked calm.

The methods in the fairy world are naturally useful, "Jiang Li, you have to control the risks. Don't let merchants with poor qualifications take advantage of you and end up with bad debts."

Jiang Li hurriedly responded.

"Well, if you have nothing to do, please step back." Xiao Yunzhou was already worried about the task of conquering Duoti.

"Hey, I've been worried a lot lately. You, the household department, need to work harder on yourselves and use your brains."

Jiang Li: "!" The money business has made so much money, why is the emperor still worried?

Jiang Lizhen admired Xiao Yunzhou a little.

The look on his face now that I'm stupid is all sincere.

He didn't understand the emperor's height.

"Wei Zheng, let the Ministry of Rites prepare and invite Sangda to enter the palace."

"I will do it for them on the last day. In addition, I will ask the cabinet ministers Fucha and Shen to come to the palace urgently to discuss. I want to open military exchanges with Wu Yunguo."

"???"

Xiao Yunzhou ignored Wei Zheng's puzzled and surprised expression.

He held the tea cup and thought.

Duoti, he has to stay to complete his mission in the fairy world!

Just as Xiao Yunzhou was thinking about it, the guards outside informed him.

"Your Majesty, it's bad! The Minister of the Ministry of Personnel and the Minister of the Ministry of Industry started fighting at the gate of Zhengyang!"

Xiao Yunzhou: "? Huh?"

"It seems like they are fighting over the credit for the thermos bottle. Both the Ministry of Officials and the Minister of Industry say it belongs to them!"

"!?"

"The Minister of War has also come and said that he wants to take it to the military camp - ah, now the Minister of War has also been beaten!"

"Master Jiang, the Minister of Hubu who just left the palace, heard about this and refused to let the Ministry of War take it away. He said that he would take it to the Ministry of Hubu for business... Ah, the Ministry of Hubu was beaten by the Ministry of War."

"..."

what?

Xiao Yunzhou was stunned for a moment.
