Cai Yan and Cai Yi returned to Cai Hejian dejectedly, they glanced at each other, and then bowed their heads at the same time and pleaded guilty to Cai Hejian: "The lowly rank failed to break through the fortress, and it is a lesson of the adult, please punish the adult!"

"What's the use of punishing you? I want to take the fortress! When are you so wasted that you can't even deal with a bunch of fish belly?" Cai Hejian scolded the two without hesitation, which was a very rare thing for him, who had always been calm.

Seeing that Elder He Jian was so angry, Cai Yan and Cai Yi didn't dare to answer, they also knew very well that this first wave of attacks not only failed to take the fortress, but suffered heavy damage, nearly three hundred soldiers lost their combat effectiveness in this wave of attacks, such heavy casualties were something they had never encountered for many years, no wonder Elder He Jian would be so angry.

After scolding Cai Yan and Cai Yi for a while, Cai Hejian's mood calmed down a little, he stared at the fortress in front of him hatefully, and said in a cold voice: "You must take this fortress, I will arrest all the people in the fortress, and let them taste the torture of my Cai clan!"

After saying that, he turned his head to Cai Yan and Cai Yi and said solemnly: "Arrange three waves of continuous offensives for me, the first wave will let ordinary soldiers go up, and you must consume the other party's means of defending the city; the second wave you will personally bring the elite, you must rush to the city for me and take a few strongholds at the head of the city; the third wave will be personally escorted by me, and I will use Taoism to support you in the back." If anyone dares to retreat without obeying the order in this attack, they will be killed, do you understand?"

"Yes, sir!"

Cai's troops quickly recovered from their previous blows, and they regrouped and divided into three obvious battle formations, as if they were about to launch an offensive again.

Li first ran to Yan Qiu's side and asked him for advice: "Boss, why did you only use thirty bed crossbows just now, if one hundred of them are powerful at the same time, you must ask the Cai family to leave one hundred more battle losses?"

Yan Qiu slapped Li Xian's head with a palm, and scolded in a low voice: "You stupid, why don't you steal? As soon as the war starts, you will exhaust all the means, how will you deal with the enemy's master later?"

"Uh! yes。。。 The boss is right, don't I understand, that's why I came to ask your old man for advice!" Li Xian said with a hippie smile, as long as he can learn the skill, it doesn't matter if he pats his head a few more times.

"Boss, what do you think Cai's formation method is for?" Li Xian asked Yan Qiu, pointing to Cai's formation.

"What else can you do? Of course, it's a split-wave attack!" Yan Qiu said with a natural expression, he saw Li Xian's ignorant look, so he explained in detail: "This kind of attack method is to divide the troops into multiple waves and continuously attack the target. The key to the success of this offensive method is that it must be able to form a sustained offensive and not give the defenders a chance to regain their strength and capture the target in one go. Generally speaking, the first wave is mostly cannon fodder, which is used to consume the target's firepower and troops, the second wave is elite, which is used to seize the city's position, and the third wave is the trump card, which is used to decide the victory or defeat. Judging from the current situation, Cai Hejian is probably planning to take action himself, and I don't know what this old guy is capable of?"

Hearing such a detailed explanation from the boss, Li Xian finally had a clear understanding of Cai Hejian's tactics, and he asked anxiously: "Then, boss, how should we deal with it?"

"All the preparations have been made, you just listen to my command, and I'll see if I can catch a few big fish like Cai Lin. Yan Qiu saw Li Xian's anxious look, but he smiled at the corner of his mouth and said calmly.

"Oh?!。。。 Li Xian's face suddenly realized, he remembered what happened to Cai Lin at that time, and immediately understood Yan Qiu's plan.

He smiled cheaply and said, "Boss, you are so insidious!"

Yan Qiu kicked it over and scolded: "No culture! How many times have you said it, this is called Wise Shenwu!"

"Yes! Yes! The boss is wise and martial, and he is clever!" Li Xian slapped him wildly, but he still thought in his heart that the boss was really insidious!

Cai's preparations for the attack were quickly completed, and Cai Hejian glanced at the hole in the wall on the fortress where Li Xian's head had once appeared, and then waved his hand and ordered: "Attack!"

"Rush!"

Cai's soldiers rushed towards the fortress with a loud roar carrying shields and war knives, and the rain of arrows on the fortress pressed down like a dark cloud of black crows.

The soldiers tried their best to hide their bodies behind the shields, but the shields were only so big that they could not block the whole body, so from time to time soldiers fell to the ground with arrows. In particular, those powerful bed crossbows, each launch will bring a bloody storm, the thin shields in the hands of the soldiers, can not stop the powerful arrows of the bed crossbow, so that the first wave of attacking soldiers suffered heavy casualties.

However, under the huge casualties, the Cai soldiers are still buried in the attack, they know very well that they have no way to retreat, of course, they may die in the hands of the enemy when they advance, but if they retreat, they will definitely die in the hands of Cai and Elder, and their families will be affected.

When Cai's soldiers rushed to the bottom of the fortress wall, they began a new round of climbing attacks. Rolling stones, logs, boiling oil, and a rain of arrows continued to attack, and the first wave of the offensive was quickly contained.

Seeing that the first wave of the attack was blocked, Cai Hejian sent an attack signal to Cai Yi and Cai Yan, and Cai Yi and Cai Yan joined the attack with the second wave of troops. In the process of attacking, although there were still rain of arrows and bed crossbows from time to time to block them, the strength of the blocking was obviously not as strong as in the first wave, which made Cai Yi and Cai Yan rush to the bottom of the fortress wall without much loss.

The soldiers led by Cai Yi and Cai Yan are all elites in the army, most of them have a certain foundation in martial arts, and some squad leaders are even masters of the internal strength level. This made them a level higher in speed, reflexes, and adaptability than the first wave of soldiers, and soon someone was attacking the city and fighting the defenders.

In the face of the crazy attack of the Cai elite, the fat man Yan Qiu had to take out the Qin team as a reserve, and the soldiers of the Qin team, under the leadership of Le Yu, formed a "small three-talent formation" and killed the Cai elite who attacked the wall, and the two sides fought together in an instant.

After all, the number of soldiers who attacked the wall of the Cai clan was limited, and the Qin team, with their tacit cooperation and huge advantage in numbers, soon gained the upper hand in the confrontation and forced the Cai soldiers down the city step by step. Cai Yi saw that his elite was about to be unable to resist, so he glanced at Cai Yan, and the two immediately rushed towards the wall with their own guards.

Cai Yi and Cai Yan's speed was getting faster and faster, and they were constantly changing their positions left and right as they went, making it difficult for the bed crossbows on the city wall to aim at them. The bodies of the two of them gradually glowed with a faint light, and the two of them turned into two bands of light, rushing towards the fortress walls at a rapid pace.

The soldiers of the Cai clan saw that the commander personally led the team to attack, and they immediately became angry, they gritted their teeth and stubbornly confronted the soldiers of the Qin team, desperately defending the stronghold at the head of the city, they firmly believed that as long as the two commanders could successfully reach the top of the city, then the victory would definitely belong to them.

Cai Yi and Cai Yan did not live up to the expectations of the soldiers, they only made two taps on the long ladder, and then jumped up and landed firmly on the top of the city. The Cai soldiers at the head of the city immediately let out a burst of cheers, as if they had won the victory.

They didn't notice that the fat man Yan Qiu had been waiting for this moment for a long time, he grinned and showed a smug smile to Li Xian, nodded and said, "Action!"

As soon as his words fell, more than 20 large nets immediately went under the cover of Cai Yi and Cai Yan's stronghold, and on these large nets, iron hooks of different sizes were embedded, and these dense iron hooks reflected a little bit of fire under the reflection of the firelight, as if they were sharp claws, and rushed towards the two of them.

These hook nets are very huge, firmly enclosing the dodge space of Cai Yi and Cai Yan, leaving them with nowhere to hide. The two of them could only use their strength, and raised their swords to slash at the hook nets, but these hook nets were very tough, and they were not strong, and the war knives not only failed to knock them away, but instead made them entangle themselves.

"Uh!~~~"

"Ahh

Cai Yi and Cai Yan both landed at the same time, and they were tightly entangled by the net hook, they instinctively struggled, but found that the more they struggled, the deeper and tighter the hook became. Before they could figure out how to deal with it, more hooks and nets were trapping them one by one.

Seeing that the two commanders were entangled in a big net, the soldiers of the Cai clan wanted to step forward to help, but how could Le Yu let them succeed? The soldiers of the Qin team immediately intensified their attack on the stronghold at the head of the city, forcing the Cai soldiers to take care of themselves.

"Bed crossbow ready!" Yan Qiu's terrifying voice sounded again, and the bed crossbows that had been hidden for a long time on the city were revealed by him, and nearly seventy bed crossbows quickly turned around and aimed at Cai Yi and Cai Yan.

"No!~~~" Cai Yi and Cai Yan were shocked when they saw so many bed crossbows aimed at them, they roared loudly in despair, and the whole person desperately jumped to the bottom of the fortress city, they would rather fall from the city than be shot into a sieve by so many bed crossbows.

"Not good!" Cai Hejian had been paying attention to the progress of the battle, seeing that Cai Yi and Cai Yan were about to capture the city wall, but they didn't expect such a reversal.

Cai Yi, Cai Yan and Cai Lin are his most powerful assistants, who have accompanied him in the southern and northern wars for many years, each of them is a master who can release his strength, and the loss of one such person has already made him heartbroken, and he must not let the other two also lose.

"Ah! The junior is crazy! Look at the benefits and disadvantages of the old man's "Flame Burst Talisman"!" Cai Hejian stretched out his hand and took out three yellow talismans from his arms, and his spiritual power was raised, and he instantly hit the head of the fortress.

At this time, the fat man Yan Qiu also gave the order to attack, and more than two hundred giant arrows were like more than two hundred poisonous bees, swooping towards Cai Yi and Cai Yan from all directions.

"Buzz, buzz, buzz!"

"Boom!"

"Boom!"

"Boom!"

Three huge explosions mixed with the "hum" of the bed crossbow rang out at the same time on the city, and three huge flames rose into the air, sweeping in all directions like a violent wind, and all the people and equipment around them were swept away.
