Chapter 774

"I'll pay my respects to my father and mother!" Merton and Princess Changle solemnly saluted in the legislative hall.

When Li Shimin saw Merton appear in front of him, he couldn't help saying, "Merton, if I'm not wrong, you've entered the palace three times in five days."

Morton said without shame, "my son-in-law is also eager to miss his wife. As the saying goes, it's like three autumn after a day's absence. In this way, your majesty will understand the mood of Weichen."

"One day's absence is like three autumn days?" Li Shimin couldn't help laughing angrily, but he had to admit that every time Merton changed his poems without authorization, he still had some charm.

Princess Changle immediately blushed and couldn't help drawing a circle on Merton's waist.

Merton couldn't help but take a breath. It turned out that this skill is regardless of age and status. Almost every woman can. It's simply an innate necessary skill.

"The child has been in the palace for many days, and it's time to go back. If the mother misses the child, the child can also go into the palace to see the queen mother at any time." Princess Changle said.

Li Shimin was suddenly hit by 10000 points. He suddenly felt that his beloved little cotton padded jacket would never come back.

Seeing this, empress Chang sun hurriedly said, "since Merton is here, how can he leave in such a hurry? Let's have a meal in the Lizheng hall today!"

"Have a meal!" Merton was immediately flattered. He had eaten the food in the imperial dining room. However, this private banquet was the first time, and was personally invited by the empress changsun.

"The son-in-law is better to obey than to be respectful." Merton immediately went down the slope.

Morton still knows that his father-in-law can have a positive bar, but his mother-in-law can't lose face.

"OK, then the palace will let the imperial dining room prepare some dishes well." the empress Chang sun nodded with satisfaction.

Merton was so treated by the empress of long sun. This honeymoon trip was of course a success. No one could see Merton's extreme care for the princess of Changle, let alone the perfume that came back as a gift, but also pleased the eldest grandson.

Although Li Shimin still doesn't deal with Merton, he also knows that he can only let go of the water thrown by his married daughter, and the eldest grandson queen has opened her mouth. He still wants to give face.

Soon, with the order of empress Chang sun, the imperial dining room was busy quickly, and Merton let them

"It is rumored that your new Qujiang bridge has built piers in the river?" Li Shimin asked. Merton's construction of piers in the river has long been popular in Chang'an city. Li Shimin naturally heard of it.

"Is there such a thing?" empress Chang sun could not help but wonder.

"Really?" Merton nodded and admitted without hesitation.

Li Shimin said with a black line on his face, "this is your Mohist bridge building technology. A small Qujiang bridge costs people and money."

Although he doesn't know how to build bridges, although the previous Qujiang bridge is an arch bridge, which directly crosses both banks, it can't be used to build a pier in the river. In Li Shimin's view, it's a waste to use such important reinforcement and cement there.

"Father, Merton's move must have deep meaning." Princess Changle defended Merton.

Li Shimin snorted coldly, "I don't see any deep meaning."

Merton stopped Princess Changle from defending again and took a deep breath: "my son-in-law believes that the length of the arch bridge can cross the river like Zhaozhou Bridge is close to the limit of the arch bridge. Even if future generations improve and the technology is advanced, it can't surpass Zhaozhou Bridge."

Li Shimin frowned and asked, "not even steel and cement?"

He had great hopes for steel and cement, but he didn't expect to hear the bad news in Merton's mouth.

Merton shook his head firmly and said, "although it is stronger, it is also extremely limited, and the reinforced concrete itself is extremely heavy. Once the span is too long, the bridge body will not be able to bear it. Over time, there will be a disaster and repeat the tragedy of the last Qujiang Bridge."

The last Qujiang bridge was damaged in a short time because of its large span and the lack of Li Chun's technology. Only then did Merton repair the bridge today.

Li Shimin suddenly said, "that's why you built piers in Qujiang River."

Merton still shook his head and said, "not so. If you build an arch bridge on the Qujiang River, the use of reinforced cement is naturally enough. However, what my son-in-law wants to conquer is not just the Qujiang River, but the Weihe River and the Yellow river wider than the Qujiang River! This Qujiang Bridge is just my son-in-law's experiment."

Once Merton talks about ink technology, his body will radiate a light of self-confidence, which people can't help being attracted.

"Test object?" Li Shimin and empress Chang sun looked at Merton with surprised eyes. Merton tried his best to set up a pier in Qujiang River. It was too expensive to test the new bridge repair technology.

"That's right! As long as the test of Qujiang bridge is successful, the Mohists have successfully summarized the technology of building piers in the river, even if the cost is more, it is worth it.

Your majesty can think that even for a wider River, as long as piers are built in the river in the dry season, several feet apart across the whole river, and then the bridge deck is paved on the foundation of these piers, before long, a bridge will span the whole two banks, and the river that could not be built is no longer an obstacle. When the long-distance people reach the river bank, they don't need to get off and take a boat to cross the river. They just need to drive across the bridge. It took an hour to cross the river, but now it takes only a quarter of an hour. " Merton said proudly.

Li Shimin immediately breathed and was shocked by the prospect described by Merton. Anyone knows that the advantage of bridge ferry is too great compared with boat ferry.

Empress Chang sun couldn't help but see that it was impossible to build an arch bridge on the too wide river, but Merton was ingenious and divided a long bridge into several small bridges. In this way, the difficulty of building a bridge was reduced several times at once. In this way, as long as bridge piers could be built in the river, even the widest river could certainly build a bridge, Building piers in the river is indeed a top priority.

"Are you sure you can build piers in the Weihe River?" Li Shimin said.

Merton nodded solemnly: "Qujiang bridge is completed. There is no difficulty in building piers in the dry season of Weihe River."

"What about the Yellow River?" Li Shimin asked eagerly, suppressing his heartbeat. "

Merton thought for a moment and said, "the middle of the Yellow River is full of silt. It can be said that it is very difficult, but the water level in the dry season is not high. If we continue to accumulate pier construction technology, my son-in-law is confident to overcome these problems."

Li Shimin nodded slowly. If Merton answered, he would not believe it. However, he believed that once Datang mastered the technology of building piers in the river, it was not impossible to build a bridge across the Yellow River, and Merton's idea would come true one day.
