Hearing Liang Bao's report, Emperor Zhou Ping smiled and put down the pen in his hand, "Hurry up and invite my Tiangong Hou in." ”

"Yes, Your Majesty." Liang Gonggong understood Li Dabao's status in Emperor Zhou Ping's heart, and he was also happy for Li Dabao.

Li Dabao was also quite enthusiastic when he saw Liang Gonggong come out in person, "Liang Gonggong has a good day." ”

Liang Gonggong smiled, "Tiangong Hou is also a good day." Your Majesty is waiting, let's go in with the miscellaneous family. ”

"Thank you, Grandpa Liang." Li Dabao was polite and followed Liang's father-in-law's side.

When he arrived at the imperial study, Emperor Zhou Ping put down the red pen in his hand and stood up, "Dabao, you are usually very busy, how can you have time to enter the palace today?" ”

After Li Dabao saluted Emperor Zhou Ping, he took out an excerpt from his sleeve, "Back to Your Majesty, it's a long story, and the micro-ministers are all written in the fold, and I ask Your Majesty to approve it." ”

Liang Gonggong took the fold and presented it to His Majesty in person.

Emperor Zhou Ping smiled and took it, "I'll take a look." ”

Emperor Zhou Ping opened the recital, and when he first looked at it, he didn't care about it, but his eyes became brighter and brighter at the end.

If it is really as Li Dabao said, there is a kind of cheap thing that can be used to build roads, and the official roads are no longer muddy, there is no need to allocate funds for road construction every year.

Emperor Zhou Ping thought of the silver used every year to repair bridges and pave roads, which would require millions of taels of silver, plus the construction of water conservancy and disaster relief, tens of millions of taels of silver a year.

It's so distressing.

"Dabao, are you really right?" Emperor Zhou Ping suppressed the excitement in his heart, and then asked in a deep voice.

If it can really be done, it will benefit the country and the people.

His wish to realize the prosperity of the Great Zhou Dynasty will definitely be achieved.

Li Dabao's attitude was respectful, but his eyes were confident, "Your Majesty, Weichen has collected some cement and tried it in the yard of his home." The road surface is really hard, and it won't be muddy even on rainy days. ”

When Emperor Zhou Ping heard this, he looked at the excerpts on the table again, and felt that those excerpts of singing praises were really boring, "Liang Bao, go out of the palace and go to Dabao's house to have a look." ”

Father-in-law Liang responded, "Yes, Your Majesty." ”

At this time, Emperor Zhou Ping said again: "By the way, go and talk to the master, let the eldest prince and the second prince also follow, and go to see together." ”

How can you increase your knowledge if you are locked up in the palace all day and don't know what is going on outside?

In the past, the child was small, and Emperor Zhou Ping was busy with things, so he didn't have time to take the child out of the palace. Now that there is such a practical opportunity, Emperor Zhou Ping certainly does not want his children to miss it.

Grandpa Liang smiled, "Yes, Your Majesty." ”

Li Dabao knew that Emperor Zhou Ping might pick a time to go over and have a look, but he didn't expect to bring two older princes with him.

Empress Zhao was also very curious when she heard that His Majesty was going to take the two princes to Li Dabao's house to see Li Dabao's new things together.

Empress Zhao Bingxue was smart and understood His Majesty's purpose in doing this, so she immediately ordered someone to prepare some things and send them to the Li family along the way.

Half an hour later, the eldest prince and the second prince, who didn't have to study, had already got into the carriage and accompanied their father out of the palace together.

Li Dabao was supposed to sit in the carriage behind, but he was also taken into the carriage by Emperor Zhou Ping.

On the surface, this carriage is a bit ordinary and not special, but there is a lot of space inside, and the decoration is quaint and practical, and the shock absorption effect is also very good.

If the teacup is placed on the handle, the tea inside will not spill.

Of course, there is only half a cup of water in the cup.

The eldest prince looked at Li Dabao and then at Emperor Zhou Ping, "Father, has Tiangonghou made something new and good again?" ”

Emperor Zhou Ping nodded and smiled: "Yes, I will open your eyes today." ”

"What's that?" The second prince couldn't wait to ask, after he knew that the throne had nothing to do with him, he concentrated on studying, especially interested in Gewuzhi.

Li Dabao replied: "A substance obtained by chance can be used to build roads. ”

"Build roads? Stones? Green bricks? The second prince asked, unthinkable, the powder turned into a hard pavement when it met water.

Li Dabao thought for a while, and then explained, "Anyway, there are some peculiarities, Your Majesty and the two princes will know it when they see it." However, there are flaws now, and they need to be improved. ”

"It's just that the process of improvement requires manpower and material resources, and it is also necessary to leave the capital to go to the right place and find the right materials. In short, Wechen feels that there is still room for improvement. ”

Emperor Zhou Ping didn't speak, he figured it out.

Li Dabao said "go to the right place", is that to leave the capital?

This is his golden pimple, and he is not worried about Li Dabao leaving.

It's not that I'm worried that Li Dabao will sell the recipe to others, but I'm worried that someone else will kidnap Li Dabao.

However, Emperor Zhou Ping put these words in his heart and did not say them.

If those things can be made in large quantities, and they can really build roads, of course Emperor Zhou Ping is willing to try Li Dabao.

The eldest prince and the second prince chatted with Li Dabao, because there was not much difference in age, they could talk.

The Li family's house in Pingkangfang is very close.

In a few moments, it arrived.

After Li Dabao got out of the carriage, he asked the porter to open the door and greet His Majesty.

However, he was stopped by Emperor Zhou Ping, "Don't move the people, I came here this time for a private visit to Weifu, just go through the side door." ”

At the insistence of Emperor Zhou Ping, he entered from the side.

Li Yuanqing was not at home today, and Liu Paner received Li Dabao's notice and immediately came over to greet her.

At the same time, Liu Paner also sent someone to inform Li Yuanqing and asked him to go home quickly.

However, Emperor Zhou Ping directly asked Li Dabao to take him to the small courtyard where the experiment was done.

Half of the space in this courtyard is covered with a layer of blue and white stuff on the ground, and there are cracks on it.

Emperor Zhou Ping asked, "Is that all?" ”

Li Dabao nodded and walked to this balanced ground, "Back to Your Majesty, it's here." It is mixed with sand and stones, and it is very hard, but because the proportions are not right, there are cracks when the sun is shining. However, giving Wechen time to experiment and readjust the formula can solve this problem. ”

Emperor Zhou Ping stood on the concrete floor and stomped on it a few times, except for two shallow footprints, which were not broken.

There was a big water tank on the side, and Emperor Zhou Ping took it personally, picked up the water scoop inside, and poured it on the cement floor.

The ground was wet, and the water was on the ground, but it didn't seep down.

Of course, where there are cracks, water seeps.

Emperor Zhou Ping's feet passed through the place where the water had been splashed, and the ground did not change except that it was wet.

Emperor Zhou Ping didn't speak, his brows furrowed slightly, and he was pondering.

After a while, the water on the concrete floor gradually evaporated, and in some places there was little water and it had dried up.

The second prince was lively, blinked his eyes, and jumped on his feet, "Father, if you use this paving on the road, you don't have to worry about the carriage getting stuck in the mud anymore, and the speed of the carriage can also be increased." ”

The eldest prince was also the same as Emperor Zhou Ping at this time, frowning and looking at Li Dabao, "If you can avoid cracks, wouldn't it be more durable to use this to build dams and ditches?" ”
