The battle of the four walls began almost at the same time.


    Liu''s private troops can barely be said to be well-trained. Therefore, after the siege order was issued, although their hearts were still full of fear of the mysterious weapons held by the Heyang garrison, these private troops still had to rush against the city wall in accordance with the requirements of the military order.


    The catapults have been assembled in the rear, and the siege ladder has also been put into use.


    Normally, the next step should be to compete with each other in the number of people who can participate in the war, and then the absolutely strong side will oppress the weak side with the number advantage.


    This is the basic law of war.


    In any war, there is no real sense of winning the strong with the weak.


    All war processes and results must conform to the law of bullying the weak.


    Even in a battle, it seems that the relatively weak side can win the final victory, but it must change the trend of strength and weakness in some parts.


    Concentrate superior forces, break through the enemy one by one, constantly accumulate war results, and finally form an overall victory.


    In the final analysis, it is still the stronger side locally.


    This law is more obvious in the war in the cold weapon era.


    But now, with Jiang Fan bringing modern hot weapons into the foreign world, the way of war has undergone earth shaking changes.


    The number of people is no longer the fundamental factor in the comparison of strength in war.


    The time gap of weapons can finally reflect the real strength of the combat power of both sides!


    When Liu''s private troops on the four walls rushed to a distance of about 20 meters, the Lin family people standing on the four walls began to throw grenades under the city like crazy!


    The landing points of these grenades are extremely accurate. Basically, they all hit the most densely populated places and the newly built siege ladders.


    The roar resounded through the fields!


    Screams were heard one after another.


    The rear catapult began to throw boulders, hoping to kill the defenders on the city wall.


    But the eight strong men arranged by the Lin family on the four walls of the city can easily jump into the air and intercept the boulders thrown by these catapults!


    In this era, giant catapults are strategic weapons, and due to difficulties in construction, they are limited in use. During the March, even if the catapults are disassembled, it is difficult to carry much, so the number is always small.


    At this time, in order to cover the retreat of the army, all the giant stone catapults carried by the army were built, but the number was very poor under the four walls.


    Under each wall, only four giant catapults can be arranged. In addition, the qualified stone materials are limited, which makes the process of intercepting these boulders very comfortable for the Lin family people who are eight grades on the city wall.


    There can be no rush at all.


    A large number of grenades hit the ground like hail. Although they can''t sweep down the enemy in pieces like heavy machine guns and block all the enemies on a line of life and death, the killing caused by these grenades is much more cruel than machine guns!


    He was swept down by bullets from a heavy machine gun and basically died on the spot.


    But most of the people who were hit by grenades were seriously injured!


    Except for a few people at the central point who will be killed on the spot, others are either missing their arms and legs, or they are full of wounds and blood.


    Unable to die on the spot, the scream and miserable appearance will create a huge psychological deterrent to those Liu''s private troops who continue to charge behind.


    The grenades were still being thrown down in a dense way, and more and more people were seriously injured. There was a wail under the city wall, like purgatory.


    A few lucky soldiers rushed through the blockade formed by grenades, but when they got to the bottom of the city, they found that basically all the cloud ladders were destroyed by grenades. They just stood under the city and couldn''t do anything.


    Without the ladder to attack the city and the pestle to hit the door, it is impossible to climb the towering city wall several feet high with both hands alone.


    The siege in this era is very boring, and there are no so-called weird tricks.


    It is to use all kinds of siege equipment, and then use human life to fill out the moat, rolling stone, thunder and wood fire oil, and then use the siege ladder as the medium to climb up the city wall, and gradually occupy the whole city wall by occupying a small area on the city wall step by step.


    Therefore, if you want to attack the city, the advantage of the number of people is essential.


    Ten encircle it and five attack it.


    In the siege, the number advantage of the attacking side must be at least five times that of the defending side, so as to ensure the victory of the siege.


    Of course, other means, such as opening the city gate and arranging insiders in advance, are not absent, but it is very difficult to achieve.


    When there is no generation difference in each other''s weapons, it still needs five times the military strength to attack the city. Now the era gap of weapons is so large that it is difficult for manpower to fill in. It can be imagined how desperate the process of attacking the city will be.


    More and more soldiers rushed under the wall.


    In order to prevent the grenade from collapsing the city wall, the throwing distance of the grenade is always kept at about 20 meters outside the city wall.


    As long as you cross this range, you will be safe temporarily.


    But the problem is that no matter how many soldiers rush over, they can''t climb the wall.


    Lost all the siege equipment, let these soldiers stand under the wall, one by one at a loss.


    What should I do next? Just stand here and wait?


    The rear is still in the roar, and still can not live the tragic death of the robe.


    There is a cold city wall ahead, and the heavy city gate has been closed. It is absolutely fantastic to push the city gate open with manpower.


    What about them... What are they?


    Suddenly, the war seemed to have nothing to do with them.


    But they rushed here desperately. What''s the meaning?


    No one can give an answer.


    Nearly half of the 20000 grenades brought by Jiang Fan were thrown out in a very short time!


    Under the bombing of tens of thousands of grenades, 100000 Liu''s private troops attacked the city, with heavy casualties!


    Almost forty or fifty thousand people were either killed or injured, while the rest were completely frightened by the explosion.


    There were about ten thousand soldiers gathered under the city wall and in front of the four gates.


    But these soldiers just stood there blankly and didn''t know what to do next.


    Other soldiers who were still alive also lost the courage to continue their charge.


    The generals who lead the team dare not urge too much. Everyone can see that the soldiers are on the verge of collapse. If they continue to supervise the war at this time, the biggest possibility is to cause mutiny. Then these generals are torn up on the spot by the mutinous soldiers!


    At this time, the heavy gates under the four walls were suddenly opened
