Generally, the effective range of the catapult is between 120 and 150 steps, which has some advantages in condescending, but the farthest is not more than 180 steps, but that is when the weight of the catapult reaches 50 catties, this weight is not the best, but it is the most stable, and the arc shot out is also the easiest to control.

On the city wall, listening to the introduction of the slinger, Lu Bu nodded, and looked at the catapult behind Cao Jun: "If you change the slings to twenty catties, how far is the range?" ”

"Back to the lord, if you change it to twenty catties, you can probably throw a distance of five hundred steps, but it is difficult to control the direction." The slinger shook his head, five hundred paces away, although the range was greatly increased, but the accuracy was reduced.

"...... like this" Lu Bu nodded when he heard this, a little disappointed, and then said: "You don't need to be precise, as long as you can roughly throw it into Cao Jun's phalanx, can you do it?" ”

"It's just a phalanx, there's no problem." The slinger nodded.

"Give it a try." Lu Bu beckoned, asked people to take an irregular stone, about twenty catties, and pointed to a phalanx at random, and the slinger tried to shoot.

"Crunch~"

Accompanied by a series of uncomplicated but extremely tedious operations, the stones were thrown by the trebuchet and smashed into the center of the phalanx.

Just like the slinger said, just the words of the phalanx, there is no problem, but Lu Bu frowned slightly, it took too long, with the current speed of the Cao army, they have advanced nearly a hundred steps, and now they are less than four hundred steps away from the city wall, this distance, once they charge, with the rate of fire of the trebuchet, I am afraid that there is no second chance to project.

"Open the oil canister, stuff it with strips of cloth and ignite it, and all catapults will be launched directly at Cao's military array without test firing!" Although the rate of fire of the trebuchet made Lu Bu dissatisfied, what he wanted to do now was to completely break the psychological pressure caused by Cao Jun, even if it was a round, Lu Bu believed that it was enough to break the psychological pressure caused by Cao Jun.

As for whether Cao Cao will learn to deal with himself in turn, it will definitely be, after all, this way, there is no technical content, although fire oil is a precious strategic material, but with Cao Cao's financial resources, the confidence is much stronger than Lu Bu, but now Lu Bu has no other way, and he can hold it for a while.

"Crunch~" In the tooth-sour voice, a jar of fire oil was sealed with a cloth plug and ignited according to the way Lu Bu said, and placed on the trebuchet.

"Boom Boom Boom~"

Twelve trebuchets ejected twelve canisters of fire oil at the same time, and Bu Sai completely ignited them in the air with the help of the fire, and from a distance, it looked like twelve fireballs falling towards Cao Jun's phalanx.

"Bang Bang Bang~"

The moment the fire oil tank shattered, the splashing fire oil instantly ignited a large area in the phalanx, and at least two hundred Cao soldiers were shrouded in flames, screaming and rolling on the ground, the originally strict phalanx was in a commotion at this moment, and quickly evolved into chaos.

"Go on, don't stop!" A flash of excitement flashed in Lu Bu's eyes, the moment the twelve canisters exploded, he knew that the oppressive atmosphere created by Cao Cao had been completely broken, and now, what he wanted to do was to expand the results of the battle and suppress the morale of Cao Jun to a greater extent.

In the distance, the drums of Cao's army became denser, and Cao's march was much faster.

"How much oil do we have?" Lu Bu waved his hand to stop the trebuchet from continuing to attack with fire oil, Cao Jun was already close to the city wall, and the trebuchet could not project, but let the trebuchet continue to suppress the opponent's catapult with the trebuchet.

"Lord, there are thirty-six cans left!" An adjutant general shouted excitedly, this moment of kung fu, the blow to Cao Jun is not light, casualties are still secondary, the most important thing is the suppression of morale, the fire oil tank landed, that is like purgatory-like scene, so that many Cao Jun are afraid, Cao Cao is also because of this, give up continuing to suppress with momentum, and at the same time, the morale of the soldiers defending the city has also been greatly encouraged, this is the law of the battlefield, one eliminates the other.

"So little?" Lu Bu frowned slightly, looked at Cao Jun who was surging up with black pressure, and said in a deep voice: "After a while, Cao Jun will press up, how can there be a cloud ladder, just throw me down a jar and ignite it!" ”

"Yes!" The lieutenant roared excitedly and went to prepare, while Lu Bu looked at Cao Jun who was pressing up, waved his hand, and said in a deep voice: "Archer, prepare to shoot on your back!" ”

"Crunch~"

A famous archer pulled the bow and arrows full, and did not aim at the Cao army below, but pointed diagonally upwards at the sky, close to a ninety degree angle to the ground, this is the experience that Lu Bu has studied in these heavenly defense cities, the arrow cluster shot at this angle falls down under the city wall, avoiding the risk of poking out his head to shoot, and the arrow cluster is extremely powerful, even if it is an arrow cluster shot by an ordinary archer, it can penetrate the wooden shield, and the impact area is also quite wide.

The Cao army under the city has begun to release arrows at the head of the city, one by one the arrows are slightly empty, with a scream shot on the city wall and the wooden shield in the front row, many unlucky soldiers were shot by stray arrows, screaming and falling to the ground, but the surrounding soldiers looked indifferent.

Lu Bu is holding an iron tire bow, shooting sharp arrows one by one, no need to aim at all, with Lu Bu's arm strength and the range of the iron tire bow, as long as he shoots out, he will be able to shoot, and sometimes the arrow cluster can even directly penetrate Cao Jun's body and submerge into Cao Jun's body behind him.

"Put!" Seeing that Cao Jun had arrived at the city, and the ladders began to be erected on the city wall, Lu Bu snorted coldly, and in the shouting, thousands of arrows fell from the sky, and there was a sudden mourning under the city wall.

"Kerose!" Lu Bu roared angrily, and the deputy general who had already prepared ordered someone to throw down the fire oil tank that had been ignited by an altar down the ladder, and thirty-six fire oil tanks went down, and the city instantly turned into a sea of fire, and in the countless screams, the pressure that had just been condensed on the city wall suddenly lightened.

Lu Bu swept towards the archer camp behind the opponent with a pair of tiger eyes, a cold light flashed in his eyes, and he said sharply: "Archer, throw!" ”

"Crunch~"

Clusters of cold arrows swept towards the opponent's back, causing the unprepared Cao Jun archers to fall in pieces.

"Keep shooting, don't stop!" Lu Bu took a deep breath, at this moment the ladder was blocked by the sea of fire, for the time being, there was no need to worry about the enemy's soldiers attacking, before the sea of fire burned out, first with the help of the height of the city wall, the opponent's archers were disabled, and Lu Bu was pleasantly surprised to find one thing, in front of the opponent's formation, there was no military general to command, which also caused these Cao troops to become chaotic after being frustrated, this is a godsend, how can you miss it.

At that moment, Lu Bu also joined the ranks of archers, and with his amazing strength, the iron-tired bow continued to hum, and clusters of arrows poured towards Cao Jun's archer camp.

"Don't mess around, the archers advance fifty paces and suppress the enemy archers!" In the rear of the Cao army, Li Dian and Cao Ren, who were in charge of the command, roared and rode their horses in the rear of the army and constantly waved their weapons, killing some Cao troops who were afraid or even fled, and at the same time urged the archers to press forward.

Looking at these two generals, Lu Bu's eyes lit up, and his eagle-like eyes fell on Cao Ren, although he didn't know who this person was, but it didn't hinder Lu Bu's enthusiasm for him, General Cao Jun, each of them was a moving achievement point.

Under Lu Bu's astonishing strength, the iron tire bow was pulled to the limit, and above the cold arrow cluster, a ray of cold light looked particularly dazzling in the sunlight.

Cao Ren was urging the archers to move forward, when he suddenly felt a chill in his heart, a cold killing machine made him fall into an ice cave, and before he could think about it, he almost instinctively turned over and fell under the horse, almost at the same time, his shoulder hurt, and a sharp arrow pierced his shoulder blade, and the terrifying power surged, almost bringing his body flying.

"General!" A group of pro-soldiers hurriedly stepped forward, protected Cao Ren tightly, helped Cao Ren up, and rushed towards Cao Ying.

"Damn!" Lu Bu slammed his fist on the city wall and stomped on it, Cao Ren's encounter also made Li Dian startled, and he instinctively rode his horse back and withdrew from Lu Bu's range, and now it would be difficult to kill him again.

The failure to harvest the generals made Lu Bu a little depressed, so he could only refocus on those archers, without the command of Cao Ren and Li Dian, these archers kept retreating under the suppression of the archers at the head of the city.

Under the city wall, the sea of fire gradually dissipated with the passage of time, but the ladder has been burned down and can no longer be used.

"Kill!" A young general rushed up along the ladder first, and when he saw Lu Bu shoot an arrow, he was about to continue to take the arrow, roared angrily, and rushed towards Lu Bu with a steel knife.

"Get out!" Lu Bu snorted angrily, and the iron tire bow in his hand smashed on the opponent's helmet, and with a bang, the iron tire bow couldn't withstand the huge force and broke directly, and the young general's helmet and head were smashed out by Lu Bu.

Lu Bu grabbed his Fang Tian painting halberd with his backhand, the halberd flashed, and another human head that had just emerged rose into the sky, and the corpse that had lost its head fell weakly, pressing down the Cao Jun below.

Lu Bu dragged Fang Tian's halberd and began to walk around the city wall, once Cao Jun rushed to the city wall, he would be attacked by Lu Bu's thunder, halberd method, archery, as the war progressed, continued to improve.

"Boom~"

A section of the city wall collapsed under the bombardment of Cao Jun's throwing stones, and a Cao army general rushed up, split two soldiers with two swords, and gained a firm foothold on the city wall.

Lu Bu was furious in his heart, and was about to drag Fang Tian's halberd to the rescue, but saw that in the crowd, a thin figure flashed, and a little silver light lit up, instantly killing the Cao general, and then with a touch of his waist, a cold light flashed, wiping the necks of the two Cao Jun, and in an instant, he forced Cao Jun, who had just gained a firm foothold, to force back.

"Nonsense!" Lu Bu's face sank.
