Zhao Bing used his brain to think of a craftsman named Dedes under the pressure of the Roman Emperor. In ancient times, both Chinese and foreign craftsmen had not had a high status. However, he could leave a name in history books as a craftsman. This shows that this person is by no means a simple character. He was very good at making various machinery in Minghe, and made many military machinery for the Roman army, and made great contributions to the expansion of Rome. Ω

Dedes once understood that a boom was not used for hanging. It was a long and heavy wooden stick or lever. It was hanging from a very high vertical bracket and could be used to destroy the chest wall at the top of the city wall, and thus derived another siege tool called the "crowbar". The boom was supported by a very high mast or vertical bracket. One end was a huge box or basket, which could be loaded with many soldiers, and the other end was pulling rigging to make the boom rise or fall.

In this way, the Romans used this lifter to hang a group of infantry over the chest wall of the city wall, cross obstacles such as the moat, and put the box directly on the enemy's city wall, and the soldiers inside could rush out to fight directly. In this way, the soldiers could be sent to the city wall continuously, complete the assault, and finally break through the city wall and seize the city. Zhao Bing thought about it and could completely learn from this "crowbar" to make similar siege equipment.

First, you have to think of a way to send the "crowbar" to the front of the city. The enemy will never let you get such a big thing done. Moreover, it is not easy to fix the water in the front of the city. Besides, there are countless bridges that block it. If the water is too deep on the boat, it is easy to get stuck and cannot reach the front of the city smoothly. After combining all the conditions, Zhao Bing observed and calculated that when the tide is high, the sea water can overflow the stone bridge in front of the city, and the flat-bottomed boat can directly reach the outside of the moat in front of the city. He can also use a large raft to set up a "crowbar" to send the soldiers on the boat directly to the city wall.

Of course, this thing seemed too simple to Zhao Bing, so he improved the crowbar. He reinforced the manned box, wrapped with a layer of cowhide on the outer layer and added a layer of iron on it, which could not penetrate the ordinary arrows. In addition, a roof cover and a shutter were added to provide all-round protection for the people inside, which also facilitated the entry and exit of the people inside. At the traction end, Zhao Bing installed a counterweight sandbox, which could easily lift the car at the other end, saving effort and improving efficiency...

After the attack order was issued, Zhao Bing stood on the deck of the ship and looked at the head of Quanzhou City. At this moment, the sky was getting lighter. The fire in the north of the city clearly shot into the sky. The feint attack on the other side had begun. Then came the explosion of flowering bullets. The lookout report that the enemy troops in the city had begun to mobilize to the north of the city. The attack on the south city also began.

To be honest, Zhao Bing was still a little worried. This kind of combat form can be said to have set a precedent for the ancient Chinese siege history, so it is a new thing for everyone. This kind of tactic was his own temporary intention. The troops participating in the war only temporarily became familiar with the procedures and had no time to practice. At present, they could only look at the results of their usual training. However, it looked pretty good, and everything was carried out in an orderly manner according to the plan. The firepower ships were already lined up one hundred and fifty steps in front of the city and unfolded their formation. The conveyor ships carrying soldiers followed up gradually, and the two teams were ready to attack.

"Your Majesty, all the troops are in their positions, and General Liu requests to start the attack!" Guan Tong saw the other party uttering a flag.

"Add to attack!" Zhao Bing nodded.

‘Boom’ As the sound of guns came to the battle position, the firepower ships entering the battle position began to be powerful. There were five firepower ships modified this time. Zhao Bing also invested a lot. Each ship was equipped with thirty crossbows of all sizes. If not enough, they were directly dismantled from other ships and arranged in a row of fifty steps. The attack surface was enough to cover the entire Nancheng, but they were outside the range of the enemy's long-range firepower, so the enemy should only be beaten and unable to hit themselves. If they could not beat them to death, they would also anger them to death.

The enemy warships were all driven under the nose, and the soldiers guarding the city were all blind. The alarm bell was knocking loudly. They were well-trained and went up to the city to draw arrows, and they were ready to fight back. But just now they were ready, and before they could breathe evenly, stone bullets and crossbow arrows were smashed overwhelmingly. This situation was not new to the Quanzhou army. The pirates in the early years and the Song army of the year before yesterday were all the same. The shield soldiers immediately stepped forward to raise their shields to block them. Others hid behind their chest walls to avoid the incoming arrows.

The Quanzhou Army was right. After several renovations, the Quanzhou city was covered with bricks and stones. Not to mention ordinary crossbows, even the stone thrower on the ship could not be shaken. But the crossbows they encountered today were called crossbows, and heavy crossbows opened bricks and cracked stones. The Quanzhou Army, which was fighting with old experience, was miserable, especially those shield soldiers responsible for cover. Even the small crossbows shot a pound of stone bullets that were enough for them to drink a pot. At the moment, the shield was destroyed and the death was extremely ugly. They were either smashed their heads or taken down to half-pull their bodies.

You should know that the crossbows have changed the history of the construction of the West. After learning about the power of the crossbows, the defending party summarized a classic defense theory. At that time, the military monograph edited by Byzantine pointed out that the thickness of the city wall should be at least more than five meters before it can withstand the attack of the crossbows. But even so, the defending party must use deep trenches and obstacles to isolate the enemy's crossbows from 150 meters away. Otherwise, once the "ten thousand crossbows" are at close range, even the gods will be unable to turn the world away.

The Quanzhou Army, hiding behind the chest wall, couldn't get much better. The mercedes built with a ruler that could not stop the rapid collision of five kilograms of stone bullets. Although they were not as exaggerated as instantly turning into powder, they also shattered into several pieces. The splashed gravel became a weapon for killing people. The light smashed a bag, the heavy one was the head was broken and the unlucky one was the brain burst, which was killed immediately.
