Zhao Yu used his brain to think that there was a craftsman named Dades under the pressure of the Roman Emperor, in ancient times, the status of both Chinese and foreign craftsmen was not high, but he could leave his name in the history books as a craftsman, it can be seen that this person is by no means a simple role, he is extremely good at inventing and manufacturing various machinery, and has made many military machines for the Roman army, and has made great contributions to the expansion of Rome.

Dades invented a boom, which was certainly not used for hanging, a long, heavy stick or lever that could be used to break down the breastwork at the top of the city wall by hanging from a very high vertical support, and from this derives another siege tool that the Romans called a 'crowbar'. The boom is supported by a tall mast or vertical support, and at one end is a large chest or basket that can hold many soldiers, and at the other end the boom can be raised or lowered by pulling rigging.

In this way, the Romans used this elevator to hoist a group of infantry over the breastwork of the wall, over obstacles such as moats, and place chests directly on the enemy's wall, so that the soldiers inside could rush out to fight. In this way, soldiers can be continuously sent to the city walls, complete the assault, and finally break through the city walls and seize the city. Zhao Hao pondered for a moment, he could completely use this 'crowbar' to make similar siege equipment.

First of all, you have to think about sending the 'crowbar' to the front of the city, and the enemy army will never let you get such a big thing safely, and the front of the city is full of water, and it is not easy to fix it in the water. In addition, there are countless bridges blocking it, and if the draft is too deep on the ship, it is easy to run aground, and it will not be able to reach the front of the city smoothly. After combining all the conditions, Zhao Hao observed and calculated, and he found that at high tide, the sea water could overflow the stone bridge in front of the city, and the flat-bottomed boat could reach the outside of the moat in front of the city. You can also use large rafts to set up 'crowbars' and transport the soldiers on board directly to the city walls.

Of course, this thing was too simple in Zhao Hao's opinion, so he improved the crowbar. He reinforced the box with people, wrapped it with a layer of cowhide and a layer of iron, which ordinary arrows could not penetrate. In addition, a roof cover and a flap are installed to protect the people inside in an all-round way, and it is also convenient for the people inside to enter and exit. At the traction end, Zhao Yu installed a counterweight sandbox, which can easily lift the car at the other end, saving effort and improving efficiency......

After the order to attack was issued, Zhao Yu stood on the deck of the ship and looked fixedly at the head of Quanzhou City, at this moment the sky has gradually brightened, the fire in the north of the city has obviously begun to feint on that side, followed by the explosion of flowering bombs, and the lookout post reports that the enemy army in the city has begun to move to the north of the city. And the attack on the southern city also began.

To be honest, Zhao Yu is still a little worried in his heart, this form of combat can be said to have opened a precedent in the history of siege in ancient China, so it is a new thing for everyone. The troops participating in the war were only temporarily familiar with the procedures, and they had no time to conduct drills at all, and they could only look at the results of their training in peacetime. However, it looks good at the moment, everything is proceeding in an orderly manner according to the plan, the firepower ships have been lined up in position one hundred and fifty steps in front of the city, and the formation has been formed, and the transport ships carrying the troops have gradually followed, showing two teams to prepare for the attack.

"Your Majesty, all the departments are in place, and Liu Dutong requests to start the attack!" Guantong saw the other party calling the flag and interpreted.

"Permission to attack!" Zhao Yu nodded.

"Boom" with a trumpet remembered, the firepower ships that entered the battle position began to exert their might, there were a total of five firepower ships modified this time, Zhao Yu also made a bloody investment, each ship was equipped with 30 ballistas of different sizes, and the ones that were not enough were directly dismantled from other ships, and they were lined up at an interval of 50 steps in pairs. The attack surface is enough to cover the entire southern city, but they are outside the range of the enemy's long-range fire, so the enemy can only be beaten and unable to hit themselves, and they will be angry if they can't be killed.

The enemy's warships drove under their noses, and the soldiers defending the city were all blind men, and the alarm bell rang loudly, and they were also well-trained, and they went to the city to fire bows and arrows, and raised swords and guns at the same time to prepare for a counterattack. But just ready, the breath has not been even, stone bullets, crossbow arrows will be overwhelmingly smashed over, this battle is not new to the Quanzhou army, the early years of the Haikou, the year before the Song army came up are this set, the shield soldiers immediately stepped forward to raise their shields to block, the others are short behind the breastwork, dodging the incoming arrows.

It is said that the practice of the Quanzhou army is not wrong, the city of Quanzhou has been repaired several times, and the rammed earth is covered with bricks and stones, not to mention the general strong crossbow, even the ship-borne stone throwing machine can not be shaken at all. But what they encounter today is not called a bed crossbow called a ballista, and the heavy ballista is a trivial matter, and the Quanzhou army that fights with old experience is miserable, especially those shield soldiers who are responsible for covering, even if a pound of stone bullets fired by a small ballista is enough for them to drink a pot, the shield is destroyed at the moment, and the death is extremely ugly, either the head is smashed off, or the body is taken down and half pulled.

You must know that the ballista once changed the history of city construction in the West, and the defending side summed up the classic defense theory after learning the power of the ballista, and the military treatise edited by Byzantium at that time pointed out that the thickness of the city wall should be at least five meters or more to withstand the attack of the ballista. But even so, the defenders must use deep trenches and obstacles to isolate the enemy's ballistas from a distance of 150 meters, otherwise once they fire '10,000 crossbows at close range', even the gods will be powerless.

The Quanzhou army hiding behind the chest wall is no better, the battlements built with a ruler wide blue bricks can not stop the rapid collision of five catties of stone bullets, although it is not as exaggerated as turning into powder in an instant, but it is also broken into several pieces, and the flying gravel has become a sharp weapon to kill, the light one smashed a bag, the heavy one is the head is broken and the blood flow, the unfortunate one is the brain burst, and he died at the moment.

And Zhao Yu was determined to conquer Quanzhou City this time, so he asked to carry out a saturation attack before the attack, clean up all the facilities that organized the assault team, and after the attack began, all the ballistae would pour stone bullets and crossbow arrows towards the head of the southern city at the maximum firing speed. The Quanzhou army was originally a species of the Song army, and the method of defending the city also inherited the way of the Song army. At first, it successfully intercepted the flying crossbow arrows, but it was ineffective against heavy stone bullets, and the drapery was torn into thousands of strands by its huge impact and inertia, turning into flying flocculents......
