The policy of banning the sea must be abolished, and Emperor Qianwu naturally has no reason to oppose the construction of docks and shipyards, so he nodded happily and agreed.

"Okay, then you can do it freely."

Li Changfeng had completed the two things he was thinking about, so he didn't linger any longer, shrunk his neck and complained: "Father, your imperial study is too cold, and your son has retired." ”

Emperor Qianwu scolded with a smile: "Stinky boy, with a stove, where is it cold?" Go back and rest. ”

Li Changfeng arched his hand casually and quickly left the palace.

Bingbing and Xiaotong already knew that Li Changfeng had returned to Beijing, and they had already prepared hot water and a table of delicious food.

Li Changfeng ate a beautiful meal, and slept until the next day before waking up, which was called a comfort.

After breakfast, Li Changfeng called Zhang Haihui and the heads of various industries under his command over to report on the business situation during this period.

The business of Diandude, Xiaogong tea and refined salt is very stable, and the previous sales volume is maintained, which can be described as a daily profit.

Affected by the cold weather, the business of the beer barbecue city has declined slightly, but the business of the hot pot at the bottom of the lake is surprisingly good, and a large number of powerful people wait in line every day.

There are even wealthy businessmen and magnates from other places who come all the way to taste it, and even the accommodation industry in the entire capital has become popular.

Li Changfeng was surprised, but realized that the reception capacity of the lake bottom fishing is far from enough to meet the market demand, and after inquiring about the output of the vegetable greenhouse, he decisively ordered the opening of a new store.

After arranging these, Li Changfeng talked about the most important thing today.

"Zhang Haihui, this prince plans to build a large shipyard, and also build a large wharf, the preliminary survey work has been launched, you go over and keep an eye on it yourself."

Zhang Haihui has followed Li Changfeng for so many years, using the most handy, strong work ability, and familiar with people from the scientific research institute, Li Changfeng plans to let him go over and roll out the preliminary work first.

When everything is in order, come back to the side and call.

"It's Your Highness!"

Zhang Haihui readily agreed.

Leaving the living room, Li Changfeng went to the bedroom.

On the road, the families were busy shoveling truckloads of coal, and the dark soot was floating all over the yard, and Li Changfeng couldn't help frowning.

When I returned to the bedroom, I felt that the room was a little cold, and there was a pungent smell wafting around, and I was even a little dizzy after staying for a long time.

"It's too cold in the north, it's better to be in the south!" Li Changfeng couldn't help but sigh.

The winter in White Rock City is not cold at all, and there is almost no need to build a stove, so you need to burn the stove for a period of time on the coldest three or nine days.

Li Changfeng opened the window to breathe, and the cold wind blew on his face, making his face a little painful.

That's when it happened.

Li Changfeng was blessed to the soul and patted his thigh.

"Oh, how did I forget about this lucrative deal?"

Li Changfeng immediately put on a sheepskin cloak and wrapped it tightly, walked out of the bedroom and shouted to the family outside the door: "Prepare the car, this prince is going to the scientific research institute." ”

When he came to the scientific research institute, Liang Dafu was frowning and meditating on a pile of drawings, and there were a bunch of uniquely shaped parts on the ground, which he didn't even notice when Li Changfeng came to his side.

Li Changfeng didn't bother, stared at the drawings for a moment, and said in surprise: "Are you developing a steam engine?" ”

"Ahh

Liang Dafu was startled, and exclaimed that it was Li Changfeng who relieved himself, patted his chest, and complained: "Your Highness, why didn't you make any noise when you came in?" ”

Li Changfeng pursed his lips: "Why is there no sound?" It's that you're too engaged, okay. ”

Liang Dafu didn't care about these trivial things, and said excitedly: "Now that artillery and muskets have begun to be mass-produced, my subordinates finally have enough time to study the steam engine, this is really a magical idea, if it succeeds, it will change the whole world!" ”

Li Changfeng smiled slightly.

The steam engine could certainly change the whole world, and it was a great invention that started the first industrial revolution and an important milestone in the progress of human civilization.

He patted Liang Dafu on the shoulder and encouraged: "It's good to know, work harder and get the steam engine out quickly." ”

Liang Dafu nodded, stared at Li Changfeng and said seriously: "Your Highness, your subordinates sometimes really suspect that you are the true god who came into the world, otherwise how could you come up with such an incredible existence as a steam engine, and even provided us with drawings of basic design ideas!" ”

"Haha, then you should be the prince of this world as a true god." Li Changfeng joked.

Liang Dafu was speechless.

Li Changfeng smiled and said the purpose of coming to the scientific research institute this time.

"Dafu, I have a good idea for the efficient use of coal here, you can take the time to do it as soon as possible to penetrate into mass production, it won't take long."

"What about inefficient use? Anyway, we don't have a shortage of coal, and I still have to work on the steam engine. Liang Dafu said reluctantly.

Liang Dafu is the leader of the scientific research institute, Li Changfeng is reluctant to lose his temper with him, so he can only explain patiently and carefully.

"Dafu, don't underestimate my idea......"

Next, Li Changfeng began to explain in detail the advantages and manufacturing methods of honeycomb coal, and Liang Dafu's eyes gradually lit up.

"Okay, this is indeed a good thing for the benefit of the country and the people, and the principle is simple and easy to manufacture, the subordinate side will immediately arrange people to study and manufacture, and it is estimated that it will be put into mass production in a few days!"

"Then the prince is waiting for your good news."

The purpose of this trip was achieved, and Li Changfeng left the scientific research institute.

Originally, he planned to go to the artillery battalion and musket battalion, but after going out, it snowed heavily, and Li Changfeng went home directly.

Three days later.

The first batch of 30 pieces of honeycomb coal was delivered to Li Changfeng's mansion.

It was also accompanied by a stove dedicated to honeycomb coal.

Li Changfeng tested the effect of honeycomb coal on the spot, and the results made him very satisfied, and then sent someone to bring a lot of ingredients, two pieces of honeycomb coal and a stove to the palace.

He didn't just make honeycomb coal to make money.

Seeing Li Changfeng, Emperor Qianwu was a little surprised.

"Stinky boy, why are you here?"

He knows his son too well, he never enters the palace if he has nothing to do, and likes to live an unrestrained life outside.

Li Changfeng smiled: "Why, can't you come to see your father if it's okay?" ”

"Is the sun coming out in the west? Why didn't I find out that you had such filial piety before? Emperor Qianwu said exaggeratedly.

Gao Dali also looked at Li Changfeng curiously, not knowing what kind of medicine he was selling in his gourd.

Li Changfeng smiled and said, "Father, how long have we not eaten together?" Today's heavy snow is suitable for eating hot pot, so Erchen brought the stove and dishes. ”

Emperor Qianwu nodded and sighed: "Our father and son have indeed not eaten together for a long time, it is rare for you to be so filial, then we will have a hot pot together today." ”
