Sun Dahai was surprised and stared, "Lord, is this the cement road? It looks very clean and clean!"

"This is the cement road built by Wang. Would uncle sun like to go down and have a try and feel his feet on the ground?" Bai Yixiu invited him. Now he is very proud to be able to build a road in ancient times.

In the future, he will build more roads and dams to benefit the people.

"OK, let me try." Sun Dahai can't wait. When the carriage stops, he immediately jumps down from the carriage, and then his feet step on the ground. The soles of his shoes are clean, and even his footprints are not left.

At this time, Bai Yixiu took out the kettle, pulled out the plug, poured some water on the ground, "Uncle sun, try this side again."

Regardless of the water on the ground, sun Dahai stepped on it directly and splashed water droplets, "Oh, there is no mud at all, and it is still so hard. Even if there is water, it will not affect the carriage journey. If this road is the same in the great Zhou Dynasty, he can go on the road no matter cloudy or rainy, which will greatly shorten the time."

Hearing this, Bai Yixiu nodded, "yes, let's start timing now. It's fifty miles from here to Tangshan. Let's see how long it takes!"

"OK, let's try it now." Sun Dahai was interested in such a road and hurried into the carriage.

The coachman heard the Lord's order, and then began to drive the carriage. Under the condition of ensuring stability and no turbulence, he tried his best to rush to Tangshan.

It used to take two hours to get to Tangshan, and the weather was fine and the road was good, but now it takes less than half the original time, which greatly shortens the trip. In addition, even in rainy days, such a road can be taken, and the time consumed will not increase too much.

At the foot of Tangshan mountain, Bai Yixiu got down from the carriage and turned around to help sun Yingying get off the carriage.

Sun Dahai followed closely and squatted on the road to check these cement floors.

At this time, some people not far away also looked over. When they saw Bai Yixiu, the dignified middle-aged man narrowed his eyes slightly, "before, your mother said that the flower magpie has a long tail, married a wife and forgot her mother. I don't believe this saying. Now I believe it."

Prince Bai Yishan, who was checking the road, was stunned when he heard the words of his father behind him. Then he looked down his father's eyes and saw that his younger brother Bai Yixiu was now talking attentively to sun YingYing and did not forget to greet sun Dahai behind him.

"Father, this road has just been repaired, and Yixiu probably hasn't had time to report it!" Prince Bai Yishan advised and explained, "besides, the formula of cement Yixiu has been handed in. He is sincere to his father. Please forgive Yixiu for his negligence."

"The boy made some achievements and couldn't help showing off in front of his father-in-law's future daughter-in-law." emperor Kang Ming said in a sour tone, "forget it, the boy is still sensible. Even if there are mistakes, I don't have the same knowledge as him."

"Father emperor is kind and magnanimous." Prince Bai Yishan complimented, and soon his attention shifted to the cement road. "Father emperor, if all the roads connecting the main cities in the great Zhou Dynasty are built into such cement roads, the people's business travel to and from will be more convenient. Even if we use troops, we can make progress day and night, and the speed is very fast."
