The attack plan of the state army was carried out in an orderly manner, while the catapults of the infantry battalion were attacking with all their might, the battalion of the shooting and the left guard battalion were recuperating, and it was not until night fell that the catapults of the battalion of the shooting battalion and the left guard battalion entered the position and took over the catapults of the infantry battalion.

  Machinery, like people, must be stopped for a period of time to maintain and maintain after experiencing high-intensity use, otherwise it will accelerate wear and tear, so that it will be damaged and scrapped.

  Therefore, after six hours of continuous use, these catapults must be retired for maintenance and maintenance, which is also necessary for rotation.

  In order to confuse the enemy army, the rotation of the Bingzhou army was chosen to be carried out after the black, after all, it was a few hundred steps apart, and the Jizhou army in the city was difficult to see

  And in the process of rotation, the catapults of the Bingzhou army almost never stopped firing, and they concentrated on attacking the city with all their might, countless stone bullets smashed on the top of their heads, and those Jizhou army sentries were suppressed so that they couldn't even raise their heads, so they could only shrink back in some dead corners of the city to avoid being stoned to death by stone bullets.

  I'm afraid they never dreamed that in the midst of this continuous attack, all the catapults of the state army could be replaced.

  The catapults of the state army were rotated in batches, and it took almost half an hour to complete the replacement, so as to ensure that the attack of the catapults would not stop, and after the rotation was completed, Yanghu and Ma Long also handed over the command to Du Pre and Xianhong, and they would go down to rest until the fifth watch tomorrow, and then take over.

  The catapults of the Shooting Battalion and the Left Guard Battalion had been recuperating for a whole day, and at this time they were all idle, and as soon as they entered the battle, they were immediately alive and vigorous, and the stone projectiles were fired fast and fiercely, and although it was night, the offensive power of the catapults was not reduced in the slightest.

  The abnormal attack posture of the Jizhou army made the Jizhou army panic, it stands to reason that at this point in time, the Jizhou army has withdrawn, and it is time for the Jizhou army to repair the city to go to the head of the city for repairs.

  After two operations, the Jizhou army has been very skilled in repairing the city wall, they have demolished a lot of houses in advance, stacked piles of beams and wood near the city wall, and then prepared a large number of iron bars, all of which have been processed in advance, and one end is burned red into a pointed shape, which is convenient for the iron bars to be nailed into the wood

  In addition, the glutinous rice juice is boiled, and it is almost with lime powder and clay.

  Originally, the Jizhou army had made all the preparations for burning the city, but the attack of the catapults of the Bingzhou army has never stopped, but has increased the attack on the city, which makes the team preparing to repair the city wall have no chance to enter the city at all.

  Although Lü Zhao did not climb the city again, he had always received news from the sentries that the catapults of the Bingzhou army had been attacking fiercely, and although the catapults were damaged from time to time, the number of damage was not large, and it did not have much impact on the attack of the catapults.

  After the attack of these six consecutive city chens, no matter how strong the city wall is, cracks will inevitably appear, and the sentinels continue to report the degree of damage to the city wall, and Lu Zhao is also secretly worried, for fear that the city wall will not be able to withstand this fierce bombardment and suddenly collapse.

  Seeing that the color gradually darkened, Lu Zhao finally secretly breathed a sigh of relief, as long as the attack of the Bai Bingzhou army did not damage the city wall, he could use one night to repair these cracks, and by Ming, the city wall of Xindu would be resurrected with full blood.

  But now it seems that something has happened, and the catapults of the state army still show no sign of stopping even though the color is already dark, and they are not going to attack completely, right?

  As soon as he thought of this, Lu Zhao suddenly broke out in a cold sweat, if the Bingzhou army really used such an attack method, it would be really bad, the damaged city wall could not be repaired, and the cracks would become bigger and bigger, which would eventually lead to the collapse of the city wall.

  It seems that the Jizhou army also discovered the secret of the Jizhou army repairing the city wall at night, so it will use non-stop attacks around the clock to destroy the Jizhou army's plan, judging from the density of stone bullets falling on the city, the Jizhou army is indeed targeted, they continue to bombard the city, that is, not to give the Jizhou army a chance to repair the city wall.

  The subordinate generals also realized the seriousness of the situation, and said to Lu Zhao: "General, the situation is not good, if the catapults of the Bingzhou army attack all night, we will not have the opportunity to repair the city wall, and now there are many cracks on the city wall, if it is not repaired in time, the city wall will be at risk of collapsing." ”

  Lu Zhao's face was solemn, this is indeed a serious problem, the reason why the city walls of Xindu can still stand until now is because they have the means to repair and maintain, if those broken city walls cannot be repaired, under the continuous attack of catapults, it will definitely be difficult to escape the fate of overturning in the end.

  Lu Zhao gritted his teeth and ordered: "All the repair teams should go to the city immediately, and at all costs, the cracks must be repaired." ”

  The team that climbed to the top of the city will definitely have casualties when facing stone bullets, but if the city wall is not repaired, the consequences will be more serious, compared with the two, Lu Zhao will definitely choose to repair the city wall, after all, compared with the safety of the entire city, it is probably normal to sacrifice some people.

  Moreover, the city is pitch black, and the location where the stone bullets of the state army fall is random, and it is impossible to achieve full coverage, sacrificing a part of the life can be exchanged for the safety of the city wall, this deal, no matter how you look at it, is quite cost-effective.

  At the sound of an order, the Jizhou army began to ascend the city, and they carried beams and trees on their backs, carrying adhesives, and moved towards the city step by step.

  The stone bullets flew in the air and constantly smashed on the city, and the Jizhou soldiers were stoned to death on the spot without leaving, which also made the surrounding Jizhou soldiers break out in a cold sweat.

  Repairing the city wall is a slow work, finding cracks, fixing beams, pouring adhesive, this process is time-consuming and laborious, and can not be sloppy at all, if the iron bar is not nailed deep enough, it is likely that you will not think of the effect of pulling, the amount of adhesive poured is insufficient, and it cannot play the role of repair, so if you want to repair the city wall, it is impossible to complete it without a lot of time.

  And everyone knows that the longer you stay in the city, the higher the risk of being hit by stone bullets, watching the robes around you continue to be smashed to death and injured, the panic of these Jizhou soldiers can be imagined, they are completely standing on the edge of hell, and if they are not careful, they will set foot on the Huangquan Road.
