Bei Wuwei was bloodlessly forced to the bank of the Yishui River by the soldiers of the King of Wuling, and it was about to overturn, both Yang Weiyuan and Zhong Qingyuan thought that this was the biggest killing.

But for Xu Rui, this is just not a problem, because he has a killer feature, that is, the pontoon bridge.

In that year, the Northern Song Dynasty Quarry Rock War, the Song army erected the Yangtze River pontoon bridge, first Fan Ruoshui used a small boat with a silk rope to measure dozens of times on the Quarry Rock River surface, and accurately measured the width of the river.

After that, Song Taizu ordered thousands of black dragon boats built in advance to transport the giant bamboo silk to Shipaikou to test the pontoon bridge, and due to careful planning, it took only three days to erect a flat pontoon bridge more than 1,000 meters long.

In addition, after the Taiping Heavenly Kingdom conquered Hanyang on December 30, 1852, in order to capture Wuchang, two Yangtze River pontoon bridges with a total length of nearly 3,000 meters were erected between Parrot Island and Baishazhou and Nan'anzui and Dadikou that night, and the speed was unprecedented.

Xu Rui naturally does not have so many resources to erect a pontoon bridge several kilometers long, but the overflow is not the Yangtze River, Tianluo Town is located in the upper reaches of the overflow, and now it is the dry season, and the overflow river is only more than 100 meters wide.

He first drew a sketch, then explained to the craftsmen how to erect the pontoon bridge, and then set up a small boat to measure the hydrological data, and completed most of the preparation work in only half an hour.

Immediately afterwards, Yang Weiyuan, according to the method dictated by Xu Rui, ordered the more than 100 fishing boats to be divided into two groups, connected side by side, to form a section of pontoon units, and then tail Xu sailed to the river, connected by thick ropes, and assembled into piers at intervals of several meters.

In this way, a large number of soldiers can work at the same time, saving a lot of time.

When the bridge piers were first completed, the army took local materials and pulled out all the door panels, bed boards, house beams, and wooden pillars in Tianluo Town to lay the bridge deck, which was fixed with iron nails and thick ropes.

In order to prevent the bridge piers from swaying with the river, Xu Rui asked Yang Weiyuan to order a weight of thirty or forty catties to be tied with hemp rope and thrown into the water as an anchor, eliminating the huge cables that are difficult to obtain, so as to speed up the construction of the bridge.

In addition, Xu Rui also cut trees and rafts on the spot, and used rafts instead of boats in the rapids of the river to reduce the surface of the water and reduce the water pressure of the bridge.

50,000 Northern Wuwei orderly division of labor, shirtless, although due to unfamiliar technology, there were several twists and turns, but with Xu Rui from the side, Yang Weiyuan and Liu Yi commanded and dispatched, it took less than three hours to build a two-meter-wide, more than 120-meter-long pontoon bridge.

At this time, the sky had just darkened, and looking at the pontoon bridge that had been born out of the sky, although it was from his own hand, the whole army still thought it was a miracle and couldn't believe it.

Yang Weiyuan stood by the Yishui River for a long time and was silent, and the river wind blew his messy hair, especially unconsciously, looking like a clay sculpture from a distance.

Liu Yi patted him lightly on the shoulder and said with a smile: "What, are you still worried that our army will not be able to return to Great Wei?" ”

Yang Weiyuan took a deep breath, spit out a long breath, and muttered: "God bless Great Wei, really God bless Great Wei!" ”

Liu Yi scoffed.

"Don't come to the rotten Confucianism, what blesses me is my million lions, but it is your righteous son who blesses me Beiwuwei, you really have a good righteous son......"

Yang Weiyuan glanced at Liu Yi and said with a smile: "Why do you want to say such sour words, don't you also plan to accept him as a righteous son, and I didn't stop you, why don't you act?" ”

Liu Yi was stunned: "Are you really willing?" ”

Yang Weiyuan shook his head, turned around and walked towards the Chinese army, Liu Yina was willing to give up and chased him all the way.

"Hey, you should make it clear, a dignified seven-foot man, the commander of the first army, why is he such a mother-in-law?"

Under the setting sun, the Beiwu guards were shocked to see a strange scene, the coach Yang Weiyuan was in a hurry, and the deputy general Liu Yi chased all the way, like two dogs fighting for food, which was passed down as a joke.

Xu Rui lay on a flatbed truck, looked at the bridge, looked at the sky, and sighed: "After crossing this bridge, I can't go back, right?" ”

Xu Fang was accustomed to the young master often saying things he didn't understand, driving the carriage, smiling to himself.

"Young master, how do you know everything? This is also a fairy spell, right? Tut-tut, conjuring a bridge out of thin air is not much better than sprinkling beans into soldiers. ”

Xu Rui rolled his eyes: "Don't be there nonsense, the army is about to cross the bridge, I'm afraid the carriage will have to be lost here, hurry up and find a cart, put my pile of jars and jars on it, if it is spilled, I can't save Xiao Jinwu, see if Zhang Zuofeng comes to you desperately." ”

Xu Fang turned his head and smiled: "Don't worry, your immortal medicine has been regarded as a treasure by the old slave in the past few days, and it is more important than life!" ”

As he spoke, Xu Fang pulled the horse's head and drove the carriage towards the guard camp.

Not far away, Wang Man watched the two of them talking and laughing, and his face was as cold as ice.

In the fifteenth year of Hongwei, on the evening of the eighth day of October, 50,000 Beiwuwei lit torches and began to cross the bridge, and all the materials that could not be taken away were pushed into the overflowing river, and ran to the sea with the floating river.

At dawn on the ninth day of October, Zhong Qingyuan's handsome army rushed to Tianluo Town, half an hour in advance, the whole army was wound with bows, knives out of sheaths, and murderous killing generals, but the huge Tianluo Town had already been empty, leaving only a mess and a little wreckage in the river.

The 50,000 troops of the Northern Martial Guard, who were supposed to fight to the death here, disappeared like the world!

The generals of the Southern Dynasty had never seen such a strange thing, and they couldn't help but look at each other, thinking of the Yin soldiers crossing the Crying Grave Valley, and the legend that the Northern Martial Guards could pass through ghosts and gods slowly spread again.

Zhong Qingyuan immediately ordered the army to disperse on the spot, and searched for the whereabouts of Beiwuwei in a dragnet style, and had the momentum to dig three feet into the ground to find out, but more than 10,000 people searched for several hours, but found nothing, all efforts failed, and Beiwuwei was still nowhere to be found.

It wasn't until half a day later that Zhong Qingyuan finally received a message from the flying pigeon on the other side.

The Southern Korean army on the east bank was encircling and annihilating the Changting Hou Department with all its might, and suddenly found the trace of the Northern Wuwei at the critical point, thinking that it was the reinforcements of the Northern Dynasty, and scared the commander into a cold sweat, and immediately mobilized heavy troops to prepare for a decisive battle.

After careful analysis, they concluded that it was the Wei army on the west bank that escaped from the encirclement, and immediately sent a letter to Zhong Qingyuan, reprimanding him for delaying the fighter.

Zhong Qingyuan held the flying pigeon to pass the book, his lips were blue, his hands trembled, and the murderous aura was scattered several meters away, and all the soldiers did not dare to approach.

On this day, Zhong Qingyuan, who has always been calm, dismounted angrily, broke the old tree with a punch with the thickness of his thigh, and the blood on his five fingers was not enough, and he raised the long knife and cut the tall horse tied to the tree into two sections, which made people feel cold.

After venting, Zhong Qingyuan calmed down again, and immediately led the army to the nearest ferry, crossed the overflow, and pursued the Northern Wuwei.

However, when they searched for the Beiwuwei on the east bank of the overflow, they were shocked to report that the 50,000 Beiwuwei army had once again forced the overflow and returned to the west bank, and it had been two days.

Zhong Qingyuan was furious, but he couldn't figure out how Beiwuwei crossed the river, so he had to return to the west bank again to continue the pursuit.

The game of cat and mouse continued, and Beiwuwei seemed to have made up his mind to use the overflow to deal with him, and the news that Beiwuwei had returned to the east bank had just crossed the river for half a day.

This time Zhong Qingyuan learned wisely, and did not rush to cross the river, but pursued along the west bank, who knew that the Northern Wuwei turned to the southeast and ran wildly all the way, running for more than a hundred miles.

In desperation, Zhong Qingyuan had to cross the river again, and as expected, Beiwuwei, who had gained the strategic initiative, turned back again, returned to the east bank again, and jumped out of the encirclement.

At this point, the two armies chased and fled far away from Jingyang, deep into the hinterland of the Southern Dynasties, and the Northern Wuwei burned and looted all the way.

Zhong Qingyuan gradually broke away from the main force of King Wuling and became a lone army, and the scope that could be controlled became smaller and smaller, and the Northern Wuwei Sidu overflowed, playing Zhong Qingyuan in a mess, and unconsciously the two armies opened up the distance of seven or eight days, and the Northern Wuwei was actually out of the control of the pursuing soldiers.

Zhong Qingyuan has always been arrogant, this time not only was he used as a monkey, but King Wuling took away most of the main force, and the hinterland of the Southern Dynasty was empty.

The sudden appearance of the Wei army shocked the officials of the various cities, and the magnates in Beijing were afraid three times a day, and the impeachment of him every day was stacked together, and it was two or three meters high.

The emperor did not dare to reprimand King Wuling, but he issued three holy decrees in a row to scold Zhong Qingyuan and send him back to the north within five days.

With such a multi-pronged approach, no matter how calm Zhong Qingyuan is, he will inevitably be impetuous, and he will be in a hurry. It was difficult for him to come up with a good way, so he had to grit his teeth and continue to eat ashes after Beiwuwei's ass.

And just when Zhong Qingyuan was anxious, Beiwuwei went around in a dashing circle hundreds of miles away from the capital of Gyeonggi in the Southern Dynasty, and then suddenly ended this inexplicable armed parade, crossed the overflow again, and turned sharply to the northeast.

Zhong Qingyuan had been dazed by this series of coquettish moves, and when he learned that Beiwuwei automatically returned north, he was subconsciously relieved, completely unaware that the enemy had achieved his strategic goal of confusing himself, and began to show his strength.
