Offensive and defensive trends, what is the situation of the Qin people, I know that Bisi is not as familiar as before, but how the Qin people are is the Qin people's own business, and the Chu State only does what the Chu State thinks should be done. Avoiding Penglai is, and building a bridge in Muze is also.

As of last year, the cement output of Chu State exceeded 120,000 tons, and it was decided to avoid the relocation of cement that had been stored and prepared for Nanzheng, Hanshui, and Guanzhong to be quickly transported to Xinying and various wharves to Xinying, but because of the limitation of the tonnage of the boat, this could only transport a part of the reserve cement, and how to deal with the remaining 40,000 or 50,000 cement was a headache for the Great Sima Mansion, and left it to the Qin people, which was the enemy; Throw it into Huaishui, it's a pity, Muze Long Bridge happened to use these tens of thousands of tons of cement.

In March, it was decided to build a bridge to relieve the siege, and within a few days, the Chu army and the Fengren master craftsmen sneaked into Muze at night to mark the bridge route, and determine the position, water depth, and flatness of the bridge piers along the line. Then more than 2,000 craftsmen in the Concrete Mansion immediately got busy, first pouring more than 750 bridge piers with mold reinforcement, these piers are about two zhang high, 30 centimeters thick, four meters in diameter, and weigh 40 tons. At the same time, more than 3,800 bridges were poured, and these bridges were of the same size, each 14 meters long, 0.72 meters wide, and 1.2 meters thick. Each bridge is also not light, weighing up to thirty tons.

Installing wooden molds, braiding ribs, pouring and pounding ......, pouring concrete is a very simple thing, plus the preparation time in the early stage, more than 2,000 craftsmen and more female laborers, more than 100 piers were poured in three months, and more than 700 corresponding bridges, and the remaining piers and bridges will be completed in four months.

Pouring is not a problem, transportation is not a problem, the key is the hoisting of piers and bridges, this is a big problem. The key was not the hoisting itself—Roman engineers could lift pedestals and statues weighing more than 50 tons by manpower, and the craftsmen could lift 40-ton piers with ease with the power of steam engines—but the destruction and obstruction of the Qin military boat division during the hoisting process.

In order to prevent the Qin army from attacking and harassing the warships, the government could only design a square building ship like a giant raft, with cranes and crane support in the center of the ship, and dense artillery around the ship. In pursuit of a high rate of fire, these guns were fitted with a spring recoil mechanism.

At the same time, the ship's four sides were also equipped with iron plates to withstand the impact of the warship, as well as wooden low walls and hand-to-hand armourers stationed behind the low walls. This is true for cranes, but also for transport ships with piers and bridges. When the huge building ship appeared on the chasm Muze, the Chu army was a sensation, the Great Liang was a sensation, and the Qin army was also a sensation. Before Wang Jian rushed to Mu Ze, Zeshang Ze'an was full of people.

The Chu people who entered Muze in the morning did not rush to build a bridge, but first sacrificed Muze with three animals, and after the sacrifice, the steam engine suddenly emitted white gas, pulled the thick silk rope on the lifting boom, and hoisted the bridge pier on the transport boat. As soon as they saw the huge bridge pier on the transport boat being lifted, the Chu people on the shore would let out bursts of cheers and jumps, and when the bridge piers fell, these people cheered again.

The Chu people were like this, and the Qin soldiers and soldiers on the Zemian war boat were also extremely shocked. Although Qin Chu is an enemy, the people of this era are still deeply in awe of nature. Huge cranes lifted huge piers and bridges, and in a matter of moments a long bridge was erected, and they couldn't help but worship the huge machine that floated above Makizawa.

The Wei and Zhao people at the head of the city of Daliang reacted very fiercely. It was besieged in December last year, and although the corn and charcoal in the city were not exhausted, the Chu army had been looking at Mu Ze from afar, and there was no action for several months, which easily made people anxious and desperate. Three months ago, the strange people informed the Chu people in the city that they had decided to build a bridge to break the siege, and it was unthinkable to build a bridge to break the siege, but what if they didn't accept it?

Hundreds of thousands of people in the city have been waiting, and after waiting for three months, they saw the huge building ship sailing into Muze, and the Chu people finally began to build bridges. Every time a bridge pier is hoisted, every time a bridge is hoisted, the Zhao Wei soldiers on the city wall will hiss and shout, until the shouting is hoarse, and the city under the city wall is also full of excitement.

"Jing people build bridges like this?" Seeing that the crane easily lifted the bridge six or seven feet long, Wang Qian, who was very thoughtful, couldn't help but exclaim.

"General Yu, Jing people do build bridges like this." Tian Pu said. The Chu people went to sea in April to avoid relocation, and the Qin army's boat division, which was worried that Shahai would be attacked by the Chu army after going to sea, returned to Daliang, Tian Pu was in charge of Daliang because it was the Qi people, and Yang Duanhe stayed in Zhifu.

"It's ...... build a bridge like this," Wang Jian was amazed and amazed, and soon realized the danger. At this speed, the bridge can be built in six months at most, and the siege of Daliang will be lifted before the decisive battle between the Qin and Chu armies, and the Wei and Zhao armies in the city will inevitably merge with the Chu army. The Chu army is already difficult to deal with, plus the three or forty thousand people of Wei and Zhao's two armies, it will be even more difficult to deal with.

"General, you must try to stop it, the last general has mobilized the war boats...... "Before Wang Jian came, Tian Pu immediately sent the war boats to attack the Chu people's building boats, but there were artillery all around the building boats, and several war boats were dispersed by artillery before they got close. During the time of waiting for Wang Qian, Tian Pu mobilized hundreds of warships to come to Muze, and these warships had already arrived.

"Can you win?" Wang Jian was not familiar with water warfare, and he could only ask Tian Pu, the general of the boat division, in water warfare.

"Although the Jingrenlou ship is large, there are only a few of them, and it is even more inconvenient to travel and turn, and if our army's war boat collides with it, it will be broken." Tian Pu was very confident in his words, and when he saw those buildings and ships for the first time, he knew that he could sink them, but the price was not small.

"Good. If you can break it today, you will break it, and you can't leave it for tomorrow. Wang Jian spoke, at this time Muze waterfront and the head of the girder burst into cheers, and the crane hoisted a new bridge pier, plus the first two bridge piers, in just four hours, there was a long bridge about twenty steps long on Muze. At this rate, eight piers can be hoisted in a day and erected into a long bridge of 80 steps, that is to say, this long bridge of more than 20 miles can be erected in 100 days.

"The last general commands!" Tian Pu agreed loudly. He knew the meaning of Wang Qian's words, he didn't have to wait, he had to deal a heavy blow to the enemy quickly, he wanted to thwart the Chu army's bridge-building operation as much as possible, and he wanted to make Zhao, Wei and Zhao in Daliang City fall into despair again.

"Herald! Drumming. Tian Pu said goodbye to Wang Jian and gave the battle order, and the drum on the five-oared war boat suddenly sounded, and it galloped on Zemian suddenly, passing Tian Pu's more detailed orders.

The sound of drums silenced the Chu army on the south bank of Muze, the Wei people and the Zhao people on the wall of the girders at the northern end of Muze. They have already seen more and more Qin army war boats on the surface of Ze, and the low bow and high stern of these war boats are always reminding people that the Great Qin Boat Division is not what it used to be, and it is no longer the Chu army war boats that rule the water of the world, but the Qin people who rule the water and lakes of the world.

To the sound of drums, hundreds of three-oared warships began to line up, and they were aiming at the crane ship that was hoisting the bridge piers. The collision was not on one side, but on four sides, and on all four sides were the collision of columns of warships in order to destroy them with a single blow.

"Da Ao ......" Xiong Jing arrived in Kaifeng with Lou Chuan, he no longer had the nasty plaster on his hands, and the broken bones had healed. Standing on the roof of the carriage, he could clearly see the crane building ship, the Qin army warboat, the King of Wei, and the Empress Dowager of Zhao who was dressed in white clothes and standing at the head of the city looking out.

"How?" Xiong Jing heard the drums, but he didn't care.

"The Qin people's war boats want to hit me, and our army ......" There are not many Qin army war boats on Ze's side, and many of the Chu soldiers rowing the war boats are on standby on the chasm, and they can rush into Muze if needed.

"How is our army?" Xiong Jing was still looking at the advocate, and his tongue subconsciously licked Tian's lips.

"Although the Lou ship has artillery, the Qin people have many war boats." Zhuang Wudi didn't know what Da Ao was thinking on his side, and thought that he cared about the war as much as he did.

"What about more?" The sound of the Qin army's drums suddenly stopped, and there were twenty-five war boats on each side, each of which listed a five-by-five boat formation. The moment before he was ready to attack, all that was quiet was the sound of the wind. Several daring boats sped for a while, causing the flags on the boats to wave, and the rumbling drums were more violent than before, and the Qin army was about to attack.
