According to Yuan Keli's guess, it is very likely that this emperor who is good at firearms tactics deliberately gave up a few sections of the city and adopted blasting attack tactics at night. Since the night blasting attack and defense has made this emperor full of victories and defeats, it is most likely that this tactic will be adopted. Therefore, when night fell, Yuan Keli only left more than 10,000 people on the top of the city, which stretched for more than ten miles, and could barely form two rows of defensive forces on the entire city head to deal with the inner side of the defensive force, and was ready to deal with the projectile attack that was likely to come at night. At the same time, many ladder boards are mounted on top of the castle head, and if something happens, the troops on the ladder board will be ready to support the castle head to launch a counterattack, and carry out the maximum blow against the defenders who are likely to retake the city wall.

In fact, of course, Xiao Xuan does not have a lot of aura that is like a god or rarely calculated by the other party, and Yuan Keli's guess is not completely wrong. It's just that as early as when the army led by Xiao Xuan returned to the division, they learned the lessons of the Battle of Linqing, and this preparation was quietly underway. After the deduction of Xiao Xuan and some of the more perceptive soldiers around him at that time: under the new siege tactics system, the city head has long been no longer a place to take a big advantage. On the contrary, there will be a lot of passivity, especially with this kind of straight traditional city wall. Before the Vauban siege method, the attacking side often had to pay several times or even more than ten times the price of the fortress, which was often worse than the traditional city wall attack and defense battle for the attacking side, but after the Vauban siege method, there was a thing that the attacking side only used half the cost of the defender and a short time to capture the fortress that seemed to be like a moat. In addition to the parallel trench system to avoid the threat of fire at the head of the city, early hand grenades were also an indispensable link.

According to previous assessments, if the weight is as easy to throw as the previous grenade, and the weight is controlled at about one pound, it is impossible to have decent power in any case. An explosion at the feet of an armored soldier does not necessarily kill or maim a person. The explosion expansion value of black powder was originally one-ninth of that of modern explosives, while the power of oriental black powder in this era was often only a few tenths of that of modern black powder. However, the actual combat in the Linqing area told Xiao Xuan: Of course, the role of the grenade is not only the killing itself, but also the deterrence and chaos effect itself, and the effect of combining the melee impact and the black powder grenade offensive is not necessarily much worse. This is especially true when the blasting rod, despite its great power, cannot be thrown continuously like multiple black powder grenades of similar weight.

Soon after the enemy troops approached the city, the team preparing for the counterattack at the head of the city began. Because it was the first battle of the new tactics, it had a very important impact on confidence and morale later, so Xiao Xuan had no intention of making do with mediocre strength. Therefore, the two enemy-controlled city heads in the north and east of the city selected from the teaching brigade a squad of about 400 people who volunteered to participate in the battle without obvious coercion, divided into eight tortoiseshell formations with armor and shields. The small phalanx of fifty people, about twenty people, formed a dense two-row team to attack forward, and the remaining thirty men were responsible for covering the flanks and rear, except for ten spearmen, the others were short spearmen and demomen, and the thirty demomen carried a total of 360 black powder grenades made from high-quality black powder captured in the Battle of Linqing. These Black Powder Grenades have largely given up lethality in pursuit of maximum acoustics, so they are not particularly dangerous to the team.

In order to avoid possible surprises during the attack, when night fell for only half an hour, the first counterattack came from the inside of the city. Almost all of the nearly 3,000 instructor brigade archers who remained behind after the expedition and the newly trained troops, as well as 1,000 instructor brigade archers who had recovered some morale, also participated in the support and cover.

The cover attack was first launched from the grenadiers behind the curtain on the inner side of the wall. After a lot of time of rigorous training, the grenadiers occupy a certain height of the bomb throwing distance, when throwing a black powder block grenade weighing no more than a pound, the bomb throw distance can generally reach about 40 meters, barely can cross the city head and high walls, to a certain extent, it is relatively safe, at least will not easily encounter the opponent's light javelin counterattack distance thrown to the left and right of the city wall, the main purpose is of course to deter the enemy at the head of the city and even under the city. At the same time, a thousand archers began to project cover one after another, of course, the focus of the attack was on the target within a certain range of the front of the assault team, in order to effectively kill the enemy without posing too much threat to their attacking team. The archers are very clever in using war bows of about seven or eight buckets. Arrows of this power level can threaten most of the Ming army's armor and even some rudimentary shields, but they are not much of a deterrent to the commandos armed according to the standards of the Jianzhou heavy infantry.

The expected blasting counterattack did not arrive, and the first counterattack to arrive began from the front line at the head of the city. Because the attacking enemy at the head of the city seemed to have been prepared, the counterattack, which included four hundred heavily armed strikers, encountered many minor setbacks at the beginning. The heavy fire of the generals' guns, large and small, led to a series of casualties and losses at the beginning. And the Ming army deployed in the direction of the counterattack at the head of the city also seems to be particularly strong. The initial attack not only did not have much effect, but became more and more passive under the suppression of the elite Ming army at the head of the city and the enemy army under the city head.

Fortunately, the officers and men of the teaching brigade who volunteered to participate in the commando mission were not mediocre, and when the grenades that were continuously thrown from the rear of the front line at the head of the city and even from the inside of the city wall to the top of the city exploded violently from the sky to the head of the city and even below the head of the city, and the rain of arrows in the air also covered both sides of the battle almost at the same time, the passive situation faced by the assault tortoiseshell formation was immediately much better. When the continuous explosions began to sound one after another under the entire enemy battle, the reinforcements of the attacking enemy below the city, and even the reinforcements on the entire city, were suddenly stagnant.

The explosions and the rain of arrows also covered the officers and soldiers who were preparing to assault in many cases, not only the black powder grenades and arrows thrown from the inside of the walls of their own defenders, but also the enemy who was responsible for covering under the city head from time to time. However, because of the pre-battle test, the commandos understood that whether it was a black powder grenade or an arrow that seemed to be not strong, the threat to their own side was not very large, and after all, they obviously had stronger immunity than their opponents psychologically, which had a decisive impact on melee hand-to-hand combat.
