In the offensive and defensive, the besieging side occupies the advantage of numbers, but the quality test of the soldiers is great, you need to see and listen to all directions, otherwise it is the end of death, the city suddenly comes to the wooden boulders, and the sudden arrows can threaten the lives of the besieging soldiers.

The advantage of the defenders is that the wounded soldiers can be transported to the city for treatment, without worrying about dying in the chaos.

The things that wrapped the cowhide made Liu Bei frown, and his eyes never left these things.

Lu Bu was also curious to look at Cao Jun's secret weapon, what was under the cowhide.

There are a lot of ladders, and those who can be selected to attack the city wall are the elite of the Cao army, they are vigorous and climb quickly, but the wood and rolling stones on the city are fatal existence for them.

Approaching the city gate, the thing wrapped in the cowhide revealed its true face, this is a rushing car, more than a dozen soldiers, pushing the rushing car, slamming towards the city gate.

With a bang, Lu Bu could feel the entire city wall trembling slightly.

Without Liu Bei's order, a boulder had already fallen, smashing the rushing car to pieces, and the rushing soldiers scattered in a hurry, and behind them, another rushing car was ready.

Liu Bei's face changed, rushing the car, the damage to the city gate is huge, according to this situation, I am afraid that the first to break through is the city gate, although the city gate of Xuzhou is strong, it can not withstand such a fatal collision of the car.

With the advantage of high places, and under the vigilance of the defenders, except for the first time, until now, no other rushing car has been able to get close to the city gate, and the rolling stones of the wood are pouring down, so that the rushing soldiers have suffered heavy losses, and the soldiers who have broken their legs are wailing under the city, looking at the falling boulder weakly.

The continuous non-stop attack, the city has been piled up densely packed with corpses of Cao soldiers, in such a siege battle, the martial arts are strong, and in the face of sudden attacks, they can only cry out in vain.

Cao's army, which was superior in numbers, attacked in rotation with various units, not giving the defenders a chance to breathe at all, and even eating could only be solved simply in the city.

As it got late, the sound of gold sounded, and Cao Jun receded like a tide, leaving corpses all over the ground.

After a day's siege, under the strict defense of the defenders, no Cao army soldiers attacked the city, and the greatest damage to the defenders was the archers of the Cao army, and the archers on the well were definitely the deadly king of Hades, but the defenders were helpless about it, there was no long-range attack equipment, if there was a bed crossbow in the city, it only took ten crosses, and the Cao army could pay a heavy price, but the bed crossbow was a taboo weapon for defending the city in this era, and the control of the imperial court was extremely strict. Now I am afraid that only in Chang'an City has such a sharp weapon.

The siege battle, Lu Bu was greatly touched, if the state army wants to fight abroad, it is inevitable to encounter such a siege war, how to reduce the loss of soldiers, has become a problem for Lu Bu to consider, Cao Jun's siege equipment, or simpler, there is a huge threat to the city gate, once the defenders are prepared, it is in vain, and if the defenders are in a hurry, the city gate can be completely sealed.

"Yes, what's missing is a long-range attack device." Lu Bu muttered to himself.

"Lord, what kind of ranged attack did you say?" Guo Jia asked, such a battle, for him, the impact is also relatively large, he thinks more about the same city, how to attack it at the lowest cost.

"Oh, nothing, just a feeling." Lu Budao: "No wonder the siege battle was ten times surrounded. ”

"My lord, go to the army to fight, and then fight the enemy, sometimes a plan can have a surprise effect." Guo Jiadao.

Lu Bu nodded slightly, Guo Jia's words are very reasonable, attacking a city, if there is a clever plan, it is much simpler.

Long-range attack equipment, Lu Bu suddenly thought of the stone throwing vehicle, if you can throw a piece of stone on the city wall, the soldier with the help of the ladder, the chance of attacking the city wall will become greater, although the lethality of the stone is limited, the psychological shadow caused to the defenders is huge, just imagine, hundreds of stone throwing vehicles are put there, the defenders on the city still dare to raise their heads, I am afraid there is no need to attack, the stone throwing vehicles hit for two days in a row, and they can collapse without attacking the defenders.

Thinking of this, the corners of Lu Bu's mouth showed a smug smile, if Bingzhou took the lead in researching this kind of thing, he would not be invincible when attacking and defending the city.

Of course, the research of bed crossbows can not be slack, Cheng Laohan made bed crossbows at the beginning, of course, the technology of bed crossbows is more complicated, relying on the craftsman workshop in Jinyang, I am afraid it will take a lot of time to study it, and the stone throwing car is simpler in Lu Bu's opinion, and the practicability is also relatively large.

"Why is the lord laughing?" Guo Jia was puzzled, after coming down from the city, his lord's behavior was a little abnormal.

"Fengxiao, I thought of a good weapon......" Lu Bu explained the purpose of the stone throwing cart in a low voice.

Guo Jia's eyes lit up when he heard this, if Bingzhou could really study this kind of sharp weapon, the siege would be much easier, and he couldn't help but say: "The lord is wise!" ”

Lu Bu proudly accepted Guo Jia's flattery, and then couldn't wait to inform the Jinyang craftsman workshop of his idea, so he found the paper, and it was not until late at night that he finished explaining this instrument, carefully sealed it, and handed it to the flying eagle in the city.

Feiying has been active in Xuzhou City, inquiring about news from all sides, after all, the Mi family is going to follow him to Bingzhou, and he has to take into account the factors that threaten the Mi family in the city, especially in recent times, the Chen family and the Cao family have been constantly targeting the Mi family, and they need to be more vigilant.

At the same time in Yanzhou, after receiving Lu Bu's reply, Zhang Miao invited Chen Gong to discuss the matter.

After reading Lu Bu's letter, Chen Gong said: "Lu Buzhi is not in Yanzhou, and it is already commendable to be able to go to Xuzhou this time, and it is also our lack of consideration. ”

"Gongtai, Cao Cao went against the grain, slaughtered civilians, there are many dissatisfaction in Yanzhou, at this time the main force of Cao's army is in Xuzhou, Yanzhou is empty, why not contact Liu Biao in Jingzhou."

Chen Gong's eyes lit up, although Liu Biao in Jingzhou did not have any entanglement with Cao Cao before, Cao Cao clearly supported Liu Yu to inherit the unification, and he already had a suspicion.

"Now that Liu Yu is dead, the successor to the unification will be determined by Liu Biao, and Liu Biaoxian's name is outside, if it is contacted, it will definitely be successful." Chen Gongdao.

After Liu Biao received the letter from Yanzhou, he was a little suspicious in his heart, and after seeing the content of the letter, he was very happy, although he was determined to develop Jingzhou, he could live in one place, since the inheritance of the unification is expected, his heart has changed, for Cao Cao, he is naturally dissatisfied, Cao Cao supported Liu Yu in Youzhou.
