At first, Ding Yi refused these things, but when he saw Du Ruhui who was smiling, he thought that he was tired to death because of his official duties, and even used the so-called pill to hang his life. He couldn't help but say it!

"Uncle Du, don't look at me like that! I'm not cursing you, but judging from the kid's experience, the pills that those Taoist priests refine are all poisons. And you have done your best and worked hard for Datang over the years. The kid can't watch Datang lose a capable minister! You should still pay attention to rest and don't get too tired! Don't take the pill, it's useless! Ding Yi looked at Du Ruhui, who was glaring angrily, and said it as tactfully as possible.

As soon as Ding finished speaking, there was silence in the carriage. Du Ruhui didn't pay attention to Ding Yi, but thought about it to himself. This kid doesn't have a bad heart, but you can't curse me just because the old man is annoying! He himself also understands his own situation, and he can only rely on some pills that Taoist priests say to support his unfinished official duties every day. Now that Ding Yi said so, he also had to think about it. It's just that today's Datang can't tolerate sloppiness!

Finally arrived at Shiping, Ding Yi's mansion before sunset.

arranged dinner and let Du Ruhui rest. See it tomorrow later!

……

When Li Er returned to the dormitory, he saw Changle holding the eldest grandson's arm and saying something.

"Haha! My good daughter! Come and let my father hug me! Li Er said and walked towards Changle.

Changle was as sensitive as ever, and avoided Li Er's coquettish saying: "Father, the beauty has grown up!" ”

Li Er had no choice but to stroke Changle's head and said greasyly: "Yes! We've grown up! But it's still my daughter! ”

Empress Eldest Sun was unhappy when she heard it, why is she still your daughter, as if she is not your daughter. Stretched out his hand and pinched Li Er's waist, and said with a strange smile: "Why is the second brother so happy today?" ”

Li Er endured the pain in his lower back and couldn't lose face in front of his daughter.

"I got something today! With this thing, there will be no famine in my Datang! Hahahaha! ”

"Ahh Second brother is joking? ”

"Father, what can make Datang no longer have famine!"

"Hahaha! Today, Ding Yi's kid offered a crop called potatoes, with a yield of twenty or thirty stones per mu! I am very relieved! According to the boy, this thing is resistant to cold and heat, and now it has been planted! Harvest in March! ”

"Second brother, is this true? Twenty or thirty stones per mu, this is really God bless my Datang! ”

"Ahh Father, was it offered by Ding Yi, the disciple of Nadeng? ”

Empress Changsun patted Changle and said, "Liqing, how can you slander the Marquis of Shiping!" That kid is dedicated to Datang, and he has brought so many things to Datang in just two months, how did he become the disciple in your mouth! Where did he offend you? ”

"Lizhi, you don't know! That kid is always different from others, and I saw him today. Although it is a little jumpy, it will not be a disciple! Li Er defended Ding Yi. Although the kid was a little rude, it wasn't excessive.

"Father and Queen Mother, that Ding Yi actually got those...... Those women's ......" Changle was a little speechless.

When Li Erchang and his grandson heard this, they also understood what was going on. After all, the two of them are the beneficiaries!

"Ahem, alright. In the future, don't talk about Shiping Hou Deng's disciples. Lizhen, you go back first, my father has something to say to your mother. Li Er interrupted the conversation in time.

"Oh well! Sons and daughters retire! Changle left a little stupidly.

"Second brother is thinking about how to arrange Ding Yi!" As soon as Changle left, Empress Changsun told Li Er her conjecture.

Li Er's face was calm, the eldest grandson really understood his thoughts.

"Yes, he's only twelve years old now! I really don't know what to do with him! Today I want to reward him, and he says that he wants to build a city of his own, and let me give him some land. What a headache for me! Li Er said helplessly.

When Empress Changsun heard this, she thought for a while and said, "Why should the second brother be like this, it is better to let Cheng Qian have more contact with him." If he wants to build a city, let him go! How is it that in my Datang, I will not fund the enemy country. ”

Li Er said: "Now the Yinhe County he is talking about is clueless! It always makes me a little unsure, let me think about it again! I can let Cheng Qian get in touch with him! ”

The two chattered a lot, all of which revolved around Ding Yi.

And Ding Yi ......

……

At dawn the next day, Ding Yi was dragged up from bed by Du Ruhui.

"Uncle Du, what time is this! It's too early! I'll sleep again! Ding Yi rubbed his eyes and said.

Du Ruhui didn't care about thirty-seven twenty-one, and dragged Ding Yi out.

In desperation, I had no choice but to let it go.

The road to Sipyeong has been laid and concrete has been laid.

The workers had never seen anything like this, and though they were curious, they did as they were told, and then poured it into the erected frame.

Someone smoothed it over and over again with a wooden plank and waited for it to dry.

Du Ruhui hastily had breakfast at Ding Yi's insistence and dragged him to the construction site. It's early, and the workers haven't started work!

Du Ruhui saw someone pouring the gray powder from the porcelain jars onto the sand and stones, and then adding water to stir. It is then filled with a tin cart and pushed into a trough that is erected with a wooden plank on one side.

"This is what you kid said about cement?" Du Ruhui pointed to the porcelain jar and asked.

"Yes! This thing is simple to make, easy to produce, and stronger than glutinous rice milk. Add water and some sand and gravel, and of course, if you are building a city wall, you can add iron bars or wood to it. It's even stronger! ”

"This thing can be dried in three or five days in summer, and about ten days in winter."

Listening to Ding Yi's explanation, Du Ruhui couldn't help but look at the section of the road that had been repaired before, stepped forward and grabbed the worker and asked, "How long has the road been paved in front of you?" ”

The worker said with some trepidation: "Lord Hui, it was repaired two days ago!" ”

Letting go of the workers, Du Ruhui walked to the side of the road that had been repaired for two days.

Ding Yi followed behind and said: "Well, this depends on the situation and it has been done, so who, bring a sledgehammer over!" ”

Du Ruhui had already stepped on the repaired concrete pavement at this time, which was very strong, although he stepped on the pavement and looked at a shallow footprint.

"Smash it hard!" Ding Yi commanded the workers and smashed the road with a hammer.

"Tom! Tong! Tong! "There were sparks flying everywhere and some dust.

The road surface is not damaged in the slightest, but there are some small potholes on the surface because it has not been completely dried.

"Haha, this thing is so strong! This way, you don't have to worry about being breached anymore! Du Ruhan said with a smile.

"Uncle Du, this hasn't been done yet, if it does, I dare to guarantee that he won't be able to smash it!" Ding Yi waved his hand to let the workers go to work, and said to Du Ruhui.

"Let's go, go back to Beijing! I want to report this to Your Majesty! ”

"Uncle Du, why don't I let someone transport some to the capital, and let Your Majesty see it!"

"So much better!"

Ding Yi asked Ding Dang to find a worker who was already familiar with cement and went to the capital with a thousand catties of cement.

Du Ruhui and Ding Yi walked first, and the workers followed.

At noon, the two had returned to Chang'an, Du Ruhui went to report to Li Er first, while Ding Yi waited for the workers.

The workers arrived and waited with Ding Yi. After a while, a eunuch came, and with Li Er's command, he built a three-foot-thick wall of concrete in the prison.

And Ding slipped away after arranging the people, so that the eunuchs who came to summon him were empty.
