As soon as the hammer fell, Sima Yunshen clearly felt that the pier was very hard, and his arm was a little numb from the shock.

When he took the hammer away, he saw that only the top layer was broken, and the bottom was still fine. This discovery made him immediately happy, and said, "Yes, yes, the hardness of this cement is really good, and if it is used to build the city wall, it will be absolutely strong." ”

"That's a must, Da Zhou's production must be a high-quality product." Lin Ran accidentally said an advertising word, Sima Yunshen was stunned when he heard it, and then laughed out loud and said, "Ah Ran is right, the products produced by Da Zhou must be high-quality." ”

After testing the hardness of the cement pier, Sima Yunshen and Lin Ran went to see the repaired cement road together. The cement road is not long, only ten meters long.

Lin Ran was used to seeing cement roads, so when he saw it, it was nothing. But Sima Yunshen was different, when he saw the smooth cement road, he didn't know what words to use to describe it.

He walked and walked on the concrete road, and asked the carriage to come over, and sat on it and tried several times. Then he said to Lin Ran, "Ah Ran, this cement road is really good, if all roads in the country are built like this, then the time to travel will be greatly reduced in the future." ”

"yes, so we have to speed up the production of this cement. It is best to build a few more cement factories in the country, otherwise if it is all transported from the capital, the cost will be high, and it will delay time. ”

"You're right, but for now, let's build the cement factory in the capital first, and then implement the road construction as soon as possible. By the way, I don't think there is anything mixed in this cement, will it be too wasteful, can you mix something into it. ”

"Of course you can, mix some stones and sand or something, it's no problem."

"It's just that in this way, will it affect the effect and hardness."

"Don't worry, it won't have much impact."

"That's good.".

The matter of building the factory was quickly decided, and the people of the Ministry of Engineering were responsible. If there is any problem, report to Lin Ran and Sima Yunshen in time.

On the way back to the palace, Sima Yunshen's mood was still very excited, and he had a feeling of high spirits.

When he returned to the palace, he heard from his subordinates that Zhai Linchuan was looking for him. However, he had just returned from outside the palace, and he didn't plan to go out again, so he directly ordered his subordinates to bring Zhai Linchuan to the palace.

In the past few days, Zhai Linchuan has been taking care of Xiao Jiu, and he has no time to find Sima Yunshen. Now, Xiao Jiu's injuries are improving, and he has time to think about his future.

He couldn't see clearly before, and he was deceived by Ying Rulan. Now that he understands everything, he wants to stay. If he stays, he can still touch Sima Yunshen's light, and it will be more convenient to do anything in the future. But if he returns to the border city, his life will remain the same.

After knowing Zhai Linchuan's thoughts, Sima Yunshen was silent for a while, and then said, "It's okay if you want to stay, but you have to promise me that I can't make trouble, otherwise I will let you go back wherever you come from." ”

"Your Majesty, don't worry, I will definitely not cause trouble for you. However, I don't have any money on hand, can I borrow some from you first? ”

"Yes!" Sima Yunshen originally planned to let Zhai Linchuan return to the border city, but now that he wanted to stay, he planned to give him another chance. After all, he is small, and he is willing to think in a good direction for the other party.

However, after returning to the dormitory at night, he still told Lin Ran about it.

Lin Ran didn't care about whether Zhai Linchuan stayed or not, as long as the other party didn't mess with her. Of course, if the other party has bad intentions, she will definitely not let it go.
