As soon as the Mid-Autumn Festival passed, the construction site of the road became noisy again.

When the first snow fell in early winter, after 200,000 people worked hard for five months, a thoroughfare more than 700 miles long and more than 10 zhang wide finally appeared in front of people.

On November 30, Li Shimin led the courtiers out of Tonghua Gate early in the morning, and looked along the newly repaired official road, the wide road was paved with smooth stones and was extremely smooth, and some stones of different colors were arranged by the Yan brothers, making you feel extremely comfortable. The cars running on the road did not seem to feel the slightest bump, and the coachmen sat in the carriages and sang a little tune leisurely.

"Sage, there is a wind and rain pavilion in five miles on this road, an inn in fifteen miles, and a post station in fifty miles, and then there will be my Datang army patrolling day and night, and those businessmen who are in a hurry to travel at night do not have to worry about safety issues on this road," Xiao Zheng said to Li Shimin as he walked.

"The Ministry of Civil Affairs and the Ministry of Industry have bothered to repair this road, and I am also grateful to the ministers" Li Daliang next to him was very happy.

"I heard that you have built an iron bridge in Weinan, this time you want to ask me to go and see it for yourself?" Li Shimin asked.

"The saint is definitely going to go, this official road is the national vein of my Tang Dynasty, and this bridge can be completed as long as it is completed, the first step of this bridge is of course for the saint to go, in order to protect my Datang 10,000-year foundation."

"I think so, I have received Qing's heart," Li Shimin said happily.

Wei Zheng looked at Xiao Zheng coldly and said: "I heard that you, Xiao Shilang, spent 300,000 catties of fine iron to repair that bridge, but fortunately, everyone knows that you are building the bridge, otherwise everyone will think that you will rebel by making weapons privately."

I didn't provoke you, why can't you get along with me, Xiao Zheng replied with a smile: "Old Wei, didn't you pick up your clothes before, and I didn't take off your pants." All the uses of my refined iron are clearly remembered by the Ministry of Industry, the Development Agency, and your Yushitai, so that I will not buckle such a big hat."

All the courtiers knew that he had this holiday with Xiao Zheng, but today Xiao Zheng said this in front of everyone, which was a bit too shameful.

But to deal with Wei Zheng, you can't have the upper hand without a ruthless way.

Hearing Xiao Zheng say this, Yu Chi Lao Hei had already laughed. Li Shimin turned around, turned his back to Wei Zheng and scolded Xiao Zheng angrily: "They are all important ministers of the court, pay attention to proportions when you speak!" ”

Although the tone was very harsh, the smile on his face couldn't be suppressed.

Li Shimin also put his hand on his chest and raised a big finger at Xiao Zheng, it seemed that Wei Zheng had squeezed Li Shimin enough, and the dignified emperor was bullied and gloated.

"You flattering minister, I'll ....... with you" Before he finished speaking, Xiao Zheng patted Wuhua's ears, and Wuhua rushed out at once, taking advantage of Wei Zheng's advantage and not running away, it would be stupid.

"Zhongqing, let's go! Could it be that the horse I'm waiting for can't outrun a cow," Li Shimin also rushed out.

On the flat official road all the way, people suddenly shouted and neighed, and everyone rushed straight to Weinan to .......

On the first day of the lunar month, it was the day when Fu Yi, the supervisor of Qintian, was selected, and Li Shimin took the courtiers to the river.

As early as three months ago, more than a dozen iron-making blast furnaces were erected by the river, and iron ingots sent from all over the country were continuously turned into molten iron, cast into steel frames, and riveted together.

Li Shimin pointed to the three huge bridge piers and exclaimed: "How much manpower and material resources have been used for these stone piers? ”。

"In the past, it would have been much more difficult to build this bridge than to go up to the sky, but now that we have something called cement, it will be much easier for us to build this bridge pier," he said, pointing to the cement in the cracks in the stones, explaining the role of this thing to everyone.

"What are these disc-like things?" Li Shili said like a curious baby.

"This thing is a pulley block, each steel frame across the bridge weighs 13,000 catties, composed of ten small steel frames, these pulley sets can easily lift thousands of pounds of heavy objects."

After Xiao Zheng finished speaking, he asked a few workers to hoist a small steel frame onto the boat in front of all the courtiers.

"Everyone, today is the last piece of steel to be bridged, and the officials invited the saints and you to come over without the slightest intention of showing off, but I want to ask you to witness the historic moment of the first year of my Tang Zhenguan" After speaking, he waved his hand to Yan Lide.

Yan Lide excitedly waved the order flag in his hand, this is a big boat on the shore carrying the assembled steel frame slowly sailed to the bottom of the bridge, standing on the shore and the bridge pier The workers used the pulley group in their hands to adjust the boat to position between the two bridges, and the steel frame was about a foot higher than the top surface of the bridge pier.

When all the courtiers were still worried that the steel frame could not be put down, along the steel frame that had been installed and the pontoon bridge that had been built, many workers lined up to send the sand bags to the boat and spread them evenly in the boat, and saw that the steel frame slowly approached the bridge pier and sent sand bags for more than an hour, and the steel frame sat firmly on the bridge pier.

The workers still did not stop, and kept sending sandbags into it, until the boat was separated from the steel frame more than two feet high, and the boat boss shouted and slowly rowed under the bridge and stopped on the shore.

"Wonderful! Pretty! Li Shimin stood still for more than two hours without moving, and when he saw the steel frame falling on it, he applauded and cheered loudly, and the ministers behind him applauded and shouted that it was worth the trip.

After the steel frame is installed, the workers carry the sleepers wrapped with iron plates and lay them on the steel frame, and after stacking, they are fixed to it with rivets.

took Li Shimin to the bridge deck and walked to the last sleeper, at this time Yan Liben held a rivet and a hammer with a plate.

"I ask the saint to hit this rivet in the last rivet," Xiao Zheng said to Li Shimin.

"Good! I'm coming! Li Shimin instantly understood what was going on, picked up the hammer and smashed the nail down.

When Li Shimin put the hammer away, the eldest grandson Wuji and the others bowed down, and the people in the distance also broke out with a shout of "long live", and the two Yan brothers burst into tears with excitement.

"This bridge marks the opening of the entire Tongtian Avenue from Chang'an to Luoyang in the Tang Dynasty, and the minister congratulates His Majesty" Xiao Zheng was also a little excited at this time.

"I thank you for your efforts!" Li Shimin hugged Xiao Zheng, then turned his head and patted Brother Yan's shoulder again.

"What do you want?" Li Shimin said happily to Xiao Zheng and the others.

"The minister asked the saint to erect a monument at the head of the bridge, and listed the important craftsmen who built this road on it, and the minister to write it, and also asked the Son of Heaven to give this bridge a name."

When the ministers got off the bridge, they found that there were a lot of clay tablets one foot square and two inches thick on the shelves under the bridge, Xiao Zheng pointed to the clay tablets and said: "Everyone, please press your hand on the clay tablets and leave your name, in the future, these clay tablets will be poured into porcelain pieces and then inlaid on the pedestal of the stele to commemorate some grand events", after speaking, he first pressed his hand into the clay adobe.

"Gong Xiao has a heart, I'll wait for you!" The eldest grandson Wuji's chubby face was so happy that the folds rose, who didn't want to take the opportunity to leave a good reputation, this time even Wei Zheng pressed his hand down silently.

After Li Shimin pressed his handprint, he lifted the pen and thought about it and said: "This bridge and this road have created a precedent for my Datang Dynasty, and I hope that my Datang Society will enjoy ten thousand years like steel and iron casting, and it will be called Wannian Bridge."

After speaking, he wrote down these three words with a pen, and immediately won the applause of the ministers.
