"Humph! This is just a weight accumulation of 5,000 catties, and it is not enough to truly reflect the advantages of the arch bridge? The old servant on the side snorted coldly.

Li Yun nodded, although the bearing weight of 100,000 catties is enough for daily use, but now what they need is to compete, of course, the bearing of 100,000 catties is not the limit of the arch bridge, and he will definitely not be convinced.

And the weight of 100,000 catties is evenly distributed on the entire bridge, which is not too difficult for a bridge, and the real test of the load-bearing capacity of the bridge is the single overweight carriage.

"Increase!" Li Yun's eyes were firm, and he roared.

"Yes!" The old servant nodded excitedly, and immediately instructed the craftsman to pull out a special four-wheeled carriage, which had eight wheels, and was modeled after the military's carriage, with a super strong load.

However, this time, in order to increase the weight of the carriage, Li Yun directly used heavier iron dians to carry the goods, and Li Yun put 20 pieces of iron tian for each 1,000 catties.

"20,000 pounds for a bicycle!"

Li Yun looked at the specially made vehicle, and couldn't help but be proud in his heart, this time, he must use practical actions to prove for himself.

"Drive!" With a clear drink from the craftsman. The carriage drove slowly and headed straight for the arch bridge.

"Such a big carriage!"

When this giant carriage successfully crossed the arch bridge, the people on both sides of the river suddenly became a sensation.

The public losers on the shore couldn't help but gasp, they naturally knew that this bicycle weighing 20,000 catties was far more difficult to test the bridge than more than a dozen 5,000-pound carriages evenly distributed on the arch bridge.

"Xiangfu's lineage!" Gong Yihong said solemnly.

However, this is not the limit of the arch bridge, and then, under Li Yun's order, the iron iron continued to increase, and the bicycle was 30,000 catties, 50,000 catties, until 80,000 catties.

And this is not that the arch bridge built by Li Yun cannot bear more load, but the weight of 90,000 catties is difficult to bear even if it is a four-wheeled carriage specially made by Li Yun, plus although the arch bridge is good, but after all, there is a certain slope, such a heavy carriage, even if it has been increased to sixteen horses to pull, but still can not pass the arch bridge.

"Eighty thousand pounds of bicycles!"

The people on both sides of the strait could not help but be in an uproar, it was the first time they had heard of such a crazy method of inspecting the bridge. The children of the public losers in the crowd gasped one by one. They know more than ordinary people, and naturally know how difficult it is for a bridge to withstand the weight of 80,000 catties of bicycles.

"Eighty thousand catties!" Princess Changle couldn't help but be startled when she heard the report from the children of the Mo family, and couldn't help but look at Mo Dun on the side worriedly, I have to say that the news of 80,000 catties of bicycles is too shocking, this is an unprecedented crazy method of bridge inspection.

When Merton heard this, he couldn't help but sigh in his heart, the Xiangfu family is really extraordinary, and this is also the reason why the carriage can't bear too much weight, if it is like the general power of later generations, the number of arch bridge load-bearing is probably much higher.

"It's just a small thing, trust your husband!" Merton patted Princess Changle's soft cheek and said confidently.

In an instant, Princess Changle's worried thoughts vanished, and whenever Merton showed this smile, she was inexplicably at ease, and she only had trust in Merton in her heart.

"Let's get started!" Morton exhaled a heavy breath of turbid air, since Li Yun had already made a move, he naturally wanted to see the move.

"Yes! Master! A disciple of the Mo family received the order and immediately hurried away.

After a while, there was a terrifying noise from the south bank, which made everyone look sideways, and soon the noise became louder and louder, and in the sight, a behemoth slowly appeared in front of everyone's eyes.

"This is a bridge erector!" The sharp-eyed Gong Yi Hao couldn't help but stretch his neck, and said in shock, the children of the other Gong Losers nodded heavily, when the Mo family laid the beam bridge, the bridge erecting machine can be said to be a sensation in the world of craftsmen in Chang'an City, and almost all the craftsmen rushed to visit the largest machinery in the history of China when they heard the news.

"Wow!" The people on both sides of the strait were shocked.

When the majestic bridge erector appeared in front of the world again, the shock in everyone's hearts did not diminish in the slightest, after all, this represents the most powerful force in the history of mankind.

"By the way, isn't the beam bridge already finished? Why does Mo Jiazi still use a bridge erecting machine? Gong Yu Hao was puzzled.

Gong Yihong on the side looked at the bridge erecting machine like a steel monster, and said with a wry smile: "Only if you are strong can you lift heavy objects, the bridge erecting machine can lift huge beams, and its own weight can be imagined, although you don't know the specific weight, but it is definitely more than 80,000 catties." ”

Gong Yihao suddenly realized: "Mo Jiazi wants to use the weight of the bridge erecting machine to correct the name of the beam bridge." ”

Gong Yihong nodded heavily: "In addition, Mo Jiazi's move has another significance, that is, the purpose of bridge construction is to make the world unimpeded. And the world's largest, the heaviest vehicle is probably a number of bridge erecting machine undoubtedly, if the bridge erecting machine can successfully pass through the beam bridge, it is not a proof that the beam bridge can meet the needs of any traffic in the world. ”

The children of the public losers nodded one after another, if the bridge erector can pass through the beam bridge today, there will be no doubts about the beam bridge in the world.

I saw that under the eyes of everyone, Wu Meiniang sat high on the bridge erecting machine, and kept giving orders to the children of the Mo family, and under the command of Wu Meiniang, the bridge erecting machine drove smoothly into the beam bridge.

"Is the bridge okay?"

"There is a girl in command."

…………………………

In the crowd, seeing the slowly moving bridge erector on the beam bridge, I couldn't help but exclaim.

"That girl is the apprentice of the Mo family!" Some people have seen the experience of Wu Meiniang commanding the bridge erector to lay the beam bridge, and they can't help but exclaim.

"Mo Jiazi's apprentice!" Gong Yihong couldn't help but glance at the son next to him, he has always been committed to cultivating his son to become a talent, but now it seems that his son may not be as good as the female apprentice of the Mo family.

The huge behemoth is like a superstar toy in Wu Meiniang's hands, and her son is obsessed with small locks, and the pattern is already too different.

As soon as the bridge erector appeared, it was immediately called the focus of the audience, and Wu Meiniang, who commanded the bridge erecting machine, was like the jewel in the crown, which was particularly eye-catching.

Everyone held their breath and stared at the beam bridge and the bridge erecting machine on the bridge deck, time instantly became frozen, every time the bridge erecting machine moved, the people on both sides of the strait couldn't help but rejoice for it, until the huge bridge erecting machine passed the beam bridge smoothly, the people on both sides of the strait instantly boiled.

"Good!" The people on both sides of the strait cheered almost at the same time.

The cheers continued one after another, directly to the arch bridge, Li Yun on the arch bridge was lost in his heart, although the load-bearing of his arch bridge has not reached the limit, but the slope of the arch bridge has limited the arch bridge can not pass too heavy carriages, and the beam bridge is not, as if the ground is flat, as long as the horsepower is enough, even the heavy goods can easily pass.

"I'm defeated!"

Li Yun said dejectedly.

His failure this time was not because he lost to Mo Jiazi again, but the arch bridge that his ancestor Li Chun was proud of was also defeated by the little-known Liang Bridge.

From then on, the enduring arch bridge in China will come to an end, and the beam bridge that is easy to erect, has an amazing load capacity, and is flat and easy to pass will become the most dazzling star in the Datang bridge industry.
