"Triangle Arrow Formation, No. 4 Tactics." Yao Beiwu did not rush to give orders, but after a brief observation, he quietly gave his order to the signal hand. The ceiling of the Beiliao airship seemed to be higher than that of its own, and it looked at least 150 feet more. In combat, it was obvious that the opponent could not fight directly at the highest limit, so he still left some allowance. Conservatively, the opponent's highest limit was 250 feet more than its own. However, the size of the opponent's airship was much smaller than that of its own, and the structure was the same.

A relatively basic open structure, maintaining stable flight at such an altitude is more difficult than one, and the shooting accuracy is difficult to guarantee. If you are a more conservative commander, you will probably disperse the formation and control your own bombing. The opponent will attack your own side at will. Basically, it is a blind cat who encounters a dead mouse. Although there are some losses, it is still acceptable. However, Yao Beiwu is not a commander of this type. Since Zhongjun Town has notified himself to pay attention to air combat, even if he is at a disadvantage in height, he still has a way to deal with it.

Airships are indeed not suitable for upward attacks. The shooting world is very limited, but after all, there is still a certain shooting world. The front is not good, and the side shooting world is better. The No. 4 tactic is specifically aimed at targets that fly higher than themselves. Six airships are composed into one group, targeting only one target, ignoring the attack and harassment of other targets on themselves. When approaching the limit range, six airships are composed into three groups, turning sharply in three directions, facing the target direction with the side, and further raising the shooting world with the roll of the airship's steering. In this way, as long as the crossbow and divine arm bow can reach the target, it can form a cross-fire shooting. These shooters of the airship team are fully confident in their artillery skills. If such cross-fire cannot eliminate a target, they will not be able to overcome the level in their hearts. Not to mention that they are now equipped with rockets with longer ranges and greater power, specifically targeting the flying targets.

The airship team quickly formed several arrows, each locked its target, and rushed straight away. The speed of the airships on both sides was naturally very fast compared to the army moving on the ground, but in the air, in this tense situation and this kind of battle situation in full swing, people on the ground could only feel that there was a leisurely atmosphere.

Relying on the advantageous height, the Beiliao airship team opened fire first. At that height, the range of the crossbows and divine arm bows they equipped was much further than usual, so they could naturally attack without restraint at the distance that the other party could not reach their own. Thick crossbow arrows flew through the airship team in arcs in the air and diagonally passed through the array of Yunzhou airship team. The first volley of the Beiliao airship, only one of the dozens of crossbow arrows hit one airship.

"Notify No. 14 to withdraw from the battle!" Yao Beiwu had no time to judge the damage of the injured airship, but he directly issued an order for safety reasons.

"Reply of No. 14: Slightly injured, a small amount affects mobility. Please continue to participate in the war." Before the signalman finished sending Yao Beiwu's order, he directly read the signal sent by the other party from the signal of the No. 14 airship.

"Agree. Go and attack the ground, keep the height, and don't give the other party a chance." Yao Beiwu ordered.

The Bei Liao airship team looked at the Yunzhou airship team approaching it at a strange speed and formation. When the Yunzhou airship turned sharply and turned its side towards itself in an instant and fired its volley, they suddenly realized that this turned out to be an extremely clever tactic. Yunzhou's attainment in airships was far more superb than they thought. During this first contact, there was no doubt that five Bei Liao airships were directly hit, and two of them were directly hit by two rockets, exploded in the air, and turned into a fireball and fell to the ground. For these more awkward airship crew members in Bei Liao, this was really a terrifying prospect.

"Don't worry, after everyone fights, we will have an advantage when we fly high." Some people in the Beiliao airship team thought this way. This is their obvious advantage. No matter how good the airships in Yunzhou have tactics, they cannot change the functions of the airship itself in battle.

After an impact, the airship teams of both sides were entangled together. The Beiliao airship occupied the advantageous height and kept shooting, and could choose the most suitable target at will. Although the hit rate was very low, it still caused damage. The Yunzhou airship could only continuously use sharp turn and raise the shooting world as much as possible to obtain the Beiliao airship. However, compared with the Beiliao airship's still immature tactics and control techniques, the airship team trained by Yao Beiwu continued to cooperate tactically between two or three airships, forming a cover for each other, and constantly forming a kill in the local area. Once the two Yunzhou airships were fired in a salvo, it was a very lucky ending to be seriously injured and withdraw from the battle. The airships of both sides were entangled in the air and seemed evenly matched.

Once the airship in Yunzhou is injured, as long as it is not too serious, it will lower its height and join the ranks of ground bombing. Although the airship team in Bei Liao seemed to have an advantage, they only destroyed three Yunzhou airships in total, and most of the others were injured. The power of Bei Liao's airships was insufficient on one hand, and Yunzhou played a more critical role in the development of airships.

Although it is a hot airship, the huge airbags of the military airship in Yunzhou are divided into lightweight leather or other materials to make the entire airbag into several relatively independent spaces. Even if it is injured, as long as the heat generator is intact, they can still maintain a certain amount of power, at least slowly descending and landing, and it is not difficult to wait for their troops to contain it. While fighting in the air, the Yunzhou army has approached Tanli and entered the sight of the Tanli defenders. Tanli defenders have completely retracted back to the city. As long as the airship does not land in Tanli, it is safe. Although the airship team has suffered unprecedented heavy losses, in fact, there are very few people who have lost.

After half an hour of fighting in the air, the siege on the ground started. Attacking several battalions in Tanli, only gave Tanli a stick of incense to decide whether to fight or surrender. They hoped to fight for too long and did not want to give the other party any other choice. While waiting for the other party to reply, the ground had already assumed a crossbow cannon and prepared various siege equipment. The infantry teams shouted slogans to prepare, and the longbowmen checked the bows in their hands, wiped the shiny compound bow body, and finally tightened the bowstrings. Their fingers picked up white tail feathers in the arrow bag, eager to try...

This atmosphere finally made the Tanli defenders feel a little unbearable. A nervous and alert archer slipped, and an arrow accidentally slid out and fell at the feet of the heavy infantry in the forefront of the Yunzhou army. This was the "provocation" that the commanders of Yunzhou had been waiting for for a long time. They ordered a full-scale attack without hesitation.

"In five minutes... I will see my soldiers standing on the top of the city." said a captain of the Light Infantry Battalion.

On the three hundred feet wide city headed by the brigade he led, the two airships accurately dropped a series of sulphur bombs. This luxurious fixed-point bombing made the entire city wall full of orange-red flames. Then came feather arrows, mercilessly drilling into the fire ball and smoke, and carried out a second strike. Under these two continuous attacks, the light infantry had rushed to the city as fast as possible, and the counterattacks they suffered were almost negligible. Less than eighty feet away from the city head, some elite archers wearing more thoughtful light armor stopped. They raised the bows in their hands, took arrows, and killed the enemy troops emerging from the city head one by one, the soldiers who wanted to push the ladder away, the strong man who splashed the oil down, and wanted to spill the boiling oil down.

The archers who leaned out to shoot arrows, those officers who shouted and pushed the soldiers to resist, were their priority targets. The enemy's attention to them was not within their consideration. In front of each elite archer, there was a heavy infantry who specifically protected them, swaying the tower shield in front of him, waving the round shield in his hand, blocking the enemy's arrows for the elite archers, and even blocking the arrows with their bodies... Standing at the forefront of the blood and fire exchange, wandering on the edge of life and death, entrusting their lives to their comrades, and using the weapons in their hands to take away the lives of the enemy's troops, and the distance you are at is enough to let you see the other party's despair before death... The elite archers are undoubtedly the most exciting job in the Longbow Camp.

In fact, after less than four minutes, a group of light infantry had already stood at the top of the city. They were inevitably injured, and even more difficult to avoid were traces of smoke and fire. However, in an incredible short period of time, they planted the Yunzhou military flag at the top of Tanli City. Then, their comrades climbed up on groups of cloud ladders and began to fight at the top of the city. When a small team of heavy infantry climbed onto the top of the city, the battle situation was almost destined. The heavy infantry rumbled towards the two wings, lost the protection of the city wall, and was then climbed to the top of the city by the opponent's lightning speed. The morale was seized, and the battle situation was almost one-sided. From the start of the attack, until the Yunzhou army took the city gate and began to enter the city sweep, until the Tanli defenders left the city and fled, and the Yunzhou army captured the entire city of Tanli, it took less than two hours in total.
