However, when the Song army was ready, dozens of black spots on the city wall suddenly attacked this way, and when the Song army did not understand what was going on, the black clicks exploded near the catapult of the Song army.

Then the screams came and went, and the accuracy of the ballista was not high, but even if it missed the catapult and landed nearby, the splashing effect was also huge, Zhang San looked at the fire people screaming and running around in the Song army's position, and those who wanted to go up to help would also be burned.

This caused a large group of people to surround the burning soldier, did not dare to go up to help, watched him burn to death, and some of the smarter wanted to run to the moat, but the distance of 300 meters basically did not run and died. Even if you run to the current medical conditions, the chances of surviving are almost zero.

It was the first time for Zhang San to see the effect of the incendiary bombs fired by the ballista at such a close distance during the day, and after reading it, he couldn't help but feel cold, thinking about what the Song army on the other side would be in the face of such a weapon?

The effect was immediately visible, after the second round of shooting began, seeing the black spots, Song Jun instantly panicked, and a fire oil bomb was far away, hitting the shield of the heavy shield hand in the front row, and the people around him ran away in an instant.

This is not over, there will be a third round and a fourth round one after another, Zhang San looked at the effect and asked Xu Guanzhong: "You said that if we go out of the city to kill for a while, can we defeat the other party?" ”

Xu Guanzhong looked at the Song army and shook his head and said: "The Song army is not in chaos, and the city gate can't rush out of too many people in a short time, and the ballistae on both sides can't be used when they engage in battle, and when enough soldiers rush out of the city, they will be adjusted, so if the two armies face each other, this is a good opportunity, but now it can only play a role in harassment." ”

Zhang San asked, "Then wouldn't it be good for us to send cavalry to charge and kill for a while?" ”

Xu Guanzhong shook his head and said: "Our cavalry is too small to achieve much success, and the king, please see, the enemy will retreat without siege equipment." ”

Sure enough, when Zhang San's Ryukyu army set fire to all the catapults of the Song army on the opposite side and began to attack the arrow tower, the rear of the Song army began to give way to a few roads, allowing the siege troops to begin to retreat.

Zhang San looked at the orderly formation of the other party's advance and retreat, and sure enough, there was no chaos, Zhang San couldn't help but sigh, the regular army is the regular army, and even the combat effectiveness of the regular army that is negligent in training should not be underestimated.

Think about the fact that the Great Song Dynasty was surrounded by the Jin army in the future, that was also because Tong Guan lost a large number of regular troops in the battle of subduing Youzhou, and the Jin army wiped out hundreds of thousands of regular Song troops in several consecutive battles, so that the soldiers guarding Tokyo in the Great Song Dynasty were all Xinding did not dare to go out of the city to fight.

The so-called soldiers and horses of the Qinwang in various places are just Zhuang Ding who was temporarily pulled up, and the reason why he didn't dare to save Tokyo was also a lesson summed up by batches of deaths, so Zhang San now feels that he still can't underestimate the Great Song Dynasty.

Originally, Zhang San also thought about whether to occupy the Yangtze River Delta, and then run Jiangnan and the Great Song Dynasty to rule the river, but now it seems that he thinks about things too simply.

For example, this time the Song army attempted to attack the city with fire oil bombs was inspired by Zhang San, although it was not successful, but this is a kind of learning, the Great Song still has its own methods, for example, the heavy infantry that appeared behind the heavy shield this time is Zhang San's opponent who is now inexplicable.

The Great Song Dynasty has always lacked horses, how to confront the cavalry of ethnic minorities with an army without horses, and the method adopted by the Great Song Dynasty is to build a city plus a combination of heavy infantry and a crossbow. The heavy infantry was covered in iron armor and weighed 50 to 60 catties, and it was difficult for even cavalry to rush when lifting heavy shields.

Or the original theory to deal with the steppe cavalry, as long as the opponent can't break through their own formation, and then they can kill and injure the enemy on a large scale, then the other party will be helpless against you, and they won't dare to fight with you.

However, the disadvantages of this tactic are also obvious, can only be a short march, can not run a long distance, relying on the camp is invincible, once in the wilderness, it is a tragedy, so the foreign invasion can only eliminate the Central Plains army outside the city, and then achieve the final victory, rarely see the victory by breaking through the city.

After the siege troops of the Song army retreated, the other troops also slowly retreated, looking at the Song army on the opposite side Zhang San sighed a little, this is war, not the kind of game that comes up and carries the ladder to die.

Sure enough, the next day the Song army did not leave the camp at all, and news came from Shiqian that the Song army on the opposite side was discussing countermeasures, and someone had already suggested the use of three-bow bed crossbows, and Tong Guan was also mobilizing bed crossbows from other places, and it was expected that a new attack would be launched after five days at the latest.

At night, the city wall quieted down, watching a large number of soldiers in the city staring at the outside of the city, looking at the black rumbling outside the city and not seeing anything, Zhang San suddenly thought of why not use ballistas to fire oil bombs, just like the kind of fire flares in World War II to defend like a vigilance, it doesn't cost much ammunition, but it can greatly improve the vision of the soldiers, and it can also better prevent sneak attacks.

Zhang San told Xu Guanzhong what he thought, Xu Guanzhong's eyes lit up when he heard it, and he immediately sent someone to prepare, and after a while, several ballistas were shot on the city wall, and there were messy landing points near and far.

The fire oil bomb fell on the ground and ignited a large area of land instantly, and the continuous burning flames illuminated a large area, which made the soldiers in the city all feel shocked, after all, there is still a lot of difference between staring at the field of black goo in the middle of the night and staring at a few points of light.

The oil bomb then slowly extinguished after a while, and a few minutes later several more rounds landed in different places, and so on, so that there was no longer any fear of a sneak attack from the opposite side.

Today's siege battle began to end hastily, and it took nearly two hours for the Song army on the opposite side to get up to eat and set up a formation, who knew that in the end, it can be said that the moat on the opposite side was defeated and retreated without even touching it.

In the middle of the night, Zhang San was awakened by the urgent news outside the door, and the herald came to report that Hangzhou City had been breached, Zhang San looked at the time and thought about how to deal with the rich people in the city after taking Hangzhou and Suzhou.

This is a wholehearted subject, and there are many choices, either to rob the other party and drive them all away or send them to be slaves, or to become friends with each other without a fan, and everyone will be like a family in the future.

You can also take them all to Ryukyu to prosper Ryukyu commerce, but each has its own advantages, but also has its own disadvantages, first of all, it is not advisable to rob the light, after robbing the light, although you can get a large amount of gold and silver in a short time, but in the future, if you want to attack a certain place, the merchants will definitely enthusiastically help the defenders of the city to defend it.

Robbed this money, it really offended the businessmen of the whole world, this is a very stupid behavior, Zhang San will definitely not do it, so this choice can be ignored, but this must appease the emotions of the soldiers.

In the second autumn, Zhang San will definitely not do it, that is not Zhang San's style, it is not easy to fight down, and he doesn't move at all, isn't that equivalent to a hard trip in vain, if he keeps doing this, what will his subordinates eat?
