The weather hasn't warmed up yet, and Xiao Chuchu can't control his longing for a modern and comfortable life.

In particular, when she saw that many of the people who inquired about the loan were wearing old cotton clothes, some of which were patched, she couldn't help but feel cold for them.

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

[But the per capita wealth is still not abundant enough, and the people are still quite few to live a well-off life. 】

Xiao Chuchu saw it with his own eyes, and he was even more distressed.

Although she wears a down jacket herself, down jackets have not yet been popularized in every house.

Xiao Chuchu feels more and more that in modern society, most people can dress and eat well, and enjoy the life of electric heating and air conditioning, how happy and how difficult it is to get.

[If Jingguo was richer, everyone could have a thermos bottle, a thermos cup, a warm baby, and a heater, how good. 】

Xiao Chuchu sighed, and his heart couldn't help but fly away.

[emm is estimated to be more difficult to use the heating of electricity, and now the technology tree has not been lit to the electricity at all. 】

[But I don't know if I can work the thermos bottle and thermos cup.] 】

Liu Wenchang, who was standing outside the carriage and preparing to talk to Liu Lanniang in the car, was stunned.

Liu Lanniang also coughed lightly with a subtle expression, stopping the urge to speak.

[Wow, my grandfather is here~ I haven't seen my grandfather for a long time! ] 】

Xiao Chuchu babbled, in the arms of the nurse in the car, enthusiastically stretched out her little short hand to the old man, begging for a hug.

[Is my grandmother okay, how is my uncle, has he found my aunt...... My eldest uncle is so old, and he is still single, hehe. 】

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

Xiao Gege is worried about these marriages?

The reincarnation of a fairy is extraordinary.

It's all to blame for her eldest uncle, who is not angry, and has not started a family so far, which makes Xiao Gege worried.

Liu Wenchang decided to go back and hurriedly urged the matchmaker to come to the door, before Liu Yannian did not get famous, 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 speak. It's windy outside, you come up and get warm. ”

Liu Lanniang opened her mouth and asked people to open the curtains.

Liu Wenchang shook his head, "It's not a big deal, it's not going to come up, your mother is still at home waiting for me to go back for dinner." ”

As he spoke, he rubbed his hands together and exhaled a white breath on the side of the street, "It won't be cold when you walk around." ”

[Oh, look at my grandfather's frozen ~ I don't know if the current technology can make thermos cups and thermoses. 】

[If I can exchange it, I'll hurry up and bring a set to my grandfather~]

Xiao Chuchu was suddenly pulled back to the beautiful idea of science and technology changing life just now.

[In the past, the thermos seemed to be made in the bottle with two layers of inner and outer tanks. 】

“！”

Liu Wenchang and Liu Lanniang immediately pricked up their ears, and they all shut up and didn't say hello.

[The inner bottle is coated with mercury. 】

[I remember when I was a child, I broke a hot water bottle and saw what it looked like......]

[If I'm not mistaken, this kind of bottle can block heat radiation to a certain extent and prevent heat from dissipating. 】

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

A bunch of bizarre words made Liu Wenchang and Liu Lanniang listen to it.

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

This must be the immortal text of the fairy world!

It's normal that he doesn't understand.

Write it down forcibly, and you may be able to decipher it later.

Liu Wenchang gritted his teeth and remembered.

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

Xiao Chuchu pondered and meditated, and finally his willow eyebrows furrowed.

[No way, who made me a liberal arts student, science knowledge is limited to high school physics, and practical invention is Daba. 】

Damei, what does it mean?

Liu Wenchang had a headache when he heard it.

What is a liberal arts student?

Science?

Now the Jingguo imperial examination is divided into two categories: civil and military.

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

His granddaughter who is the reincarnation of a fairy, in the fairy world, is in charge of literature?

Liu Wenchang tried his best to keep up with his granddaughter's divergent voice, thinking that if Xiao Chuchu knew about it, he would probably laugh out loud in the middle of the night.

Xiao Chuchu thought irresponsibly, and finally ended with a sigh, [I don't know if our Jingguo's current scientific research talents, my uncle, can make a thermos cup. 】

[Eh, this rotten system, I can't count on it, I don't have anything. Uncle is much more reliable than the system. 】

Liu Wenchang: "......! ”

"Huh," he quickly glanced at his daughter, Liu Luniang, "I heard that you are now acting as an agent for the harem?" ”

"Then hurry back to the palace, Dad, I'm going home too, I have to go back to watch the boss who can't be made."

Liu Lanniang's face changed, and she quickly understood, and said, "Dad, then the next time you enter the palace with your eldest brother, I will take Xiao Gege to see you." ”

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

[Hey, what does my mother do with my grandfather's pen and ink? 】

Xiao Chuchu was curious.

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

But soon, after Liu Wenchang left the carriage for some distance, he quickly walked to no one and wrote hastily with a pen.

'Inner and outer tank', 'mercury', 'two-layer hollow'......

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

"Boss," Liu Wenchang rushed into the house of his eldest son Liu Runnian, pushed open the door, and shouted, "Something is coming!" ”

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

Liu Runnian: "......? ”

He looked up from the tall pile of silk books.

"What do you see? You're not going to do it, are you? Liu Wenchang raised his head and straightened his chest, "It's okay, I have already thought of how to do it, I will teach you a few mantras." ”

“…… Dad, did you go out today to see Xiao Gege? ”

"Don't talk nonsense, I'm not, I don't have ......"

"What did little Gege Xianyin say?"

“……”

*

The card game of "who is the rich man" is in full swing in the major grocery stores in the capital.

There are two types of shops: plain paper and hardcover wood.

Simple pack, with a wooden box, only half a tael of silver.

Hardcover, five taels of silver.

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

"I've heard that Tobe adults all play this game."

"What's more, it's written in this hardcover brocade box, this one is the same as the emperor in the palace!"

“！ It's too indecent. Haven't you heard, the great Confucian Shen Mian and the second assistant all wrote a poem for this board game. The square inch of the table, travel all over the world, know all the reason, so the emperor gave the name of board game. ”

“！”

"The emperor and the household department came up with a new loan strategy from this 'big rich man', also known as 'Jingguo Money Bank' board game."

The students in the capital, the literati, and even the businessmen who were curious about the new policy of the household, and the common people who had a little spare money, couldn't wait to buy a simple or hardcover, or in the teahouse or at home, and studied it.

As soon as I researched it, I was fascinated!

In addition, he was deeply aware of the necessity of borrowing money banks.

- If you want to buy land, do business, and become a rich man, ask the money bank to borrow, it's really fragrant!

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

"Your Majesty, a rough estimate is that next month, there will be tens of thousands of taels of interest on our loan."

Jiang Li of the household department couldn't keep his mouth shut.

Xiao Yunzhou's face was calm.

The method of the immortal realm is naturally useful, "Jiang Li, you have to control the risk. Don't be taken advantage of by poorly qualified merchants, and end up with bad debts. ”

Jiang Li hurriedly responded.

"Well, you can step down if it's okay." Xiao Yunzhou was already worried about the task of Raider Duoti.

"Eh, I've been worrying a lot lately, so you have to work hard and use your brains."

Jiang Li: "! "The money is so earned, why does the emperor still have trouble?

Jiang Li really admired Xiao Yunzhou a little.

He now showed a 'dull' expression, all sincerely.

The height of the emperor, he doesn't understand.

"Wei Zheng, go and let the Ministry of Rites prepare, and invite Sanda into the palace."

"I have to practice for them on the last day, and in addition, I will urgently enter the palace to discuss with the cabinet Fucha and Lord Shen, and I want to open military exchanges with Wu Yunguo."

“？？？”

Xiao Yunzhou ignored Wei Zheng's puzzled expression.

He pondered with his teacup.

Duoti, he has to stay in order to complete the fairy realm mission!

Xiao Yunzhou was thinking about it, and the guards outside reported it.

"Your Majesty, it's not good! The secretary of the ministry and the secretary of the Ministry of Industry fought at the gate of Zhengyang! ”

Xiao Yunzhou: "? Well? ”

"It seems that they are fighting for the credit of some thermos flask, and the Ministry of Officials and the Ministry of Industry both say that they are theirs!"

“！？”

"The secretary of the military department is also here, saying that he is going to take it to the barracks - ah, now the secretary of the military department has also been beaten!"

"Lord Jiang, the head of the household department who had just left the palace, heard about this matter and did not let the military department take it away, saying that he would take it to the household department to do business...... Ah, the head of the household was beaten by the military department. ”

“……”

What is it?

Xiao Yunzhou was stunned when he heard this.
