"The sons and daughters meet their fathers and queen mothers!" In the Lizheng Palace, Merton and Princess Changle saluted solemnly.

Li Shimin saw Merton appear in front of him, and couldn't help but be speechless for a while: "Merton, if I am not mistaken, you have entered the palace three times in five days." ”

Merton said without shame: "The son-in-law is also thinking about his wife, as the saying goes, if you don't see each other for a day, your majesty will understand the mood of Weichen." ”

"If you don't see each other, it's like three autumns?" Li Shimin couldn't help laughing angrily, but he had to admit that every time Merton changed the poems without authorization, he still had a bit of charm.

Princess Changle suddenly blushed, and couldn't help but reach out and draw a circle on Merton's waist.

Morton couldn't help but gasp in pain, it turns out that this skill is regardless of era and status, almost every woman will, it is simply an innate and necessary skill.

"The child has been in the palace for many days, and it is time to go back, if the mother misses the child, the child can also enter the palace at any time to visit the queen mother." Princess Changle spoke.

Li Shimin suddenly received a 10,000-point critical hit, and the feeling of being a woman who was not left behind suddenly rose in his heart, and he only felt that his beloved little padded jacket might never come back.

Seeing this, Empress Eldest Sun hurriedly said: "Since Merton is here, how can he be in such a hurry to leave, let's have a meal in the Lizheng Hall today!" ”

"Eat!" Merton suddenly felt flattered, he had eaten the food in the imperial dining room, but this was the first time that such a private banquet was held, and it was personally invited by the eldest grandson empress.

"Then the son-in-law is better to be respectful than to obey his fate." Merton immediately borrowed the slope to descend the donkey road.

The father-in-law can face the bar, but the mother-in-law can't help but give face, and Merton still knows this truth.

"Okay, then the palace will let the imperial dining room prepare a few dishes." Empress Eldest Sun nodded with satisfaction.

The reason why Merton was treated so heavily by the eldest grandson queen, this honeymoon trip was of course indispensable, anyone could see Merton's extreme intentions for Princess Changle, not to mention the perfume when he returned as a gift, which made the eldest grandson queen extremely satisfied, you must know that in addition to the eldest grandson Wuji, Merton was the first person to let her personally invite to entertain.

Although Li Shimin still doesn't deal with each other with Merton, he also knows that the water spilled by his married daughter can only let go now, and the eldest grandson queen has already opened her mouth, and he still has to give this face.

Soon, with the orders of Empress Changsun, the imperial dining room quickly became busy, and the Modon and the others let it

"According to rumors, your newly built Qujiang Bridge actually built piers in the middle of the river?" Li Shimin asked. Merton's construction of bridge piers in the river had already been rumored in Chang'an City, and Li Shimin naturally heard about it.

"Is there such a thing?" Empress Eldest Sun couldn't help but be surprised.

"Is that true?" Merton nodded, admitting without hesitation.

Li Shimin said with a black line on his face: "This is your Mo family's bridge building technology, a small Qujiang bridge is so laborious and costly." ”

Although he didn't know how to repair the bridge, although the previous Qujiang Bridge was an arch bridge, directly across both banks, where could it be used to build a bridge pier in the river, in Li Shimin's view, it was a waste to use such an important reinforced concrete there.

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

Li Shimin snorted coldly and said, "Why didn't I see any deep meaning. ”

Merton stopped Princess Changle from defending again, took a deep breath and said: "The son-in-law thinks that the length of the arch bridge can cross the river like the Zhaozhou Bridge, which is already close to the limit of the arch bridge. ”

Li Shimin frowned and asked, "Even if it's reinforced concrete?" ”

He had great hopes for the concrete, but he did not expect to hear the bad news from Merton's mouth now.

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 definitely not be able to withstand it, and in time, there will inevitably be a disaster, repeating the tragedy of the previous Qujiang bridge." ”

The last Qujiang bridge was damaged in a short period of time because the span was too large and there was no Li Chun's technology, so there was the reason why Merton repaired the bridge today.

Li Shimin suddenly said: "That's why you built a bridge pier in the Qujiang River." ”

Merton still shook his head and said: "That's not the case, if you build an arch bridge on the Qujiang River, the use of reinforced concrete is naturally enough, but what the son-in-law wants to conquer is not just the small river Qujiang, but the Wei River and the Yellow River, which are wider than the Qujiang River!" This Qujiang Bridge is just a test for my son-in-law. ”

When Merton talks about ink skills, he will exude a confident glow on his body, and people can't help but be attracted to it.

"Experiments?" Li Shimin and Empress Changsun both looked at Merton with surprised eyes, and Merton tried his best to build a bridge pier in the Qujiang River, in order to test the new bridge repair technology, which was too expensive.

"Not bad! As long as the test of the Qujiang Bridge is successful, and the Mo family succeeds in summing up the technology of building bridge piers in the river, it will be worth the cost.

Your Majesty can think that even if the river is wide, as long as the bridge piers are built in the middle of the river during the dry season, spanning the entire river surface at intervals of several zhang, and then the bridge deck is paved with the foundation of these piers, it will not be long before a bridge will span the entire bank, and the river that could not be repaired will no longer be an obstacle. When the people who have traveled long distances reach the riverbank, they no longer need to get out of the car and take a boat to cross the river, they only need to drive across the bridge, which used to take an hour, but now it only takes a quarter of an hour. Merton said proudly.

Li Shimin's breath suddenly stagnated, and he couldn't help but be shocked by the prospect depicted by Merton, everyone knew that compared with the boat ferry, the advantage of the bridge ferry was too great.

Empress Changsun couldn't help but be amazed, it is true that the too wide river surface cannot be built into an arch bridge, but Merton has ingenuity to divide a long bridge into several small bridges, so that the difficulty of building a bridge is reduced several times at once, so that as long as the bridge piers can be built in the river, even if the river surface is wide, the bridge can definitely be built, so that the construction of bridge piers in the river is indeed the top priority.

"Are you sure you can build piers in the Wei River." Li Shimin is colorful.

Merton nodded solemnly and said: "The Qujiang Bridge was completed, and there is no difficulty in building the bridge piers during the dry period of the Wei River. ”

"What about the Yellow River?" Li Shimin suppressed his heartbeat and asked expectantly. ”

Merton thought for a moment and said: "The Yellow River is full of silt, which can be said to be extremely difficult, but the water level is not high during the dry season, and if we continue to accumulate the technology to build bridge piers, my son-in-law is confident that he can overcome these problems." ”

Li Shimin nodded slowly, if Merton agreed, he would not believe it, but he believed that once the Tang Dynasty mastered the technology of building bridge piers in the river, it was not impossible to build a bridge across the Yellow River, and Merton's idea would be realized one day.
