As Li Ru expected, even though the archers of the Cao army attacked in turns, they did not stop much.

In just a quarter of an hour, the density of the arrow rain was much smaller, and it was possible to counterattack, but it was not necessary, so it was still just defense.

After another quarter of an hour, with such a high-intensity archery, Cao Jun's archers' hands could no longer be raised, and some soldiers simply swollen their arms in a large circle, which would not be better for a while.

The rain of arrows was about to stop, and Li Ru shouted: "General, hurry~"

"Crossbowmen ready~"

The crossbowmen who had been hiding behind the shield soldiers had long been holding their breath, and when they heard the order, they were ready almost in the blink of an eye.

As soon as the arrow rain stopped, Zhang Xiu shouted angrily-

"Put~"

More than 1,000 arrows, divided into two batches on the left and right, fell steadily into the Cao army's arrow array. The shield soldiers protected them motionlessly, but as soon as they released the last arrow, they were too tired to do it, and nearly a hundred people reacted a little slower, and they fell to the ground after being hit by the arrow.

After a wave, the shield soldiers and archers all reacted, and the formation slowly retreated backwards. Instead, 5,000 Cao troops pushed siege equipment and launched a fierce assault.

The real war began -

"Kill~"

"Arrow~"

The sudden and fierce momentum of the two sides, Li Ru didn't take it to heart, his eyes looked fixedly at the city-breaking car that had just appeared, frowned and said secretly: Is it wrong? What Prime Minister Cao Cheng wants is to break the city like this? But that's not possible! The city gate has long been blocked, what's the use of this broken city?

Li Ru thought about it, Zhang Xiu did not forget to command his soldiers to meet the enemy, and had already taken the lives of hundreds of Cao soldiers. Li Ru came back to his senses and said, "General, use a catapult!" ”

Zhang Xiu was stunned at first, and then she was overjoyed: "Okay! Use catapults to smash these bastards. ”

"Catapult Preparation~"

With Zhang Xiu's chanting, the catapult, which had been waiting for several days, immediately showed its fangs, and one by one the stone bullets were put up, and the hinges were quickly filled under the efforts of the officers and men in the army.

"Put~"

With the waving of the Ling Flag, eight catapults fired at the same time, and eight stone projectiles with large grinding plates crossed the city wall and rushed towards the Cao army outside the city.

In the first round of shooting, only three stone bullets hit, but the lethality was comparable to a round of arrow attacks, causing hundreds of casualties to Cao's army.

Cao Cao, who was outside the city, did not expect that the range of the Ming army's catapult could reach such a distance, and he was also a little stunned for a while, but he came back to his senses and immediately ordered to retreat.

It's just that although he is fast, the catapult is faster. These further improved catapults not only have a range of three miles, but also a much faster speed than before, saving most of the time. The catapult first adjusted its orientation according to the observation of the observer, and then launched again under the wave of the flag.

This time, only one of the eight stone bullets missed, and the other seven all fell into the Cao army, killing and injuring at least 1,000 people, and the morale of the Cao army plummeted for a while.

Rao is the Cao army who is besieging the city is a carefully selected elite, and when he saw his comrades retreating, he couldn't help but be a little slower. It was these few points that caused many people to lose their lives, and they were stoned to death and injured by the rolling stones and skulls thrown from the city.

"Splash~"

Zhang Xiu knew that the opportunity could not be missed after a long time on the battlefield, and with a shout, the hot oil that had been prepared rolled down.

"Ah...... It's scalding......"

"Help...... Burning people...... Help ......"

"It's not good, it's oil, everyone retreat~"

Zhang Xiu listened to the shouts of the city, and said in his heart: It's not that there are no smart people, they actually know this thing, hehe~

While snickering in his heart, Zhang Xiu waved his hand without hesitation: "Rocket waiting~"

"Yes!"

Immediately, the rockets ignited by three or five flew down the city, and as soon as they landed, they brought a wave of heat, and the screams started again.

"Help...... Help me...... Brother, save ......"

"Save Me ......"

"Save ...... Yes...... Ahem~"

The billowing smoke made these Cao soldiers who shouted for help cough again, it was really ...... A difficulty has not gone, and a difficulty has come!

Hot oil, in fact, was miners under Gongsun Du who dug up crude oil, and the amount was not much, but after the separation of primitive means, most of it was stored and left for use after the rise of science and technology, and some of it was transferred to various armies and used as a killer weapon. Whether it is besieging or defending a city, this thing will become an irresistible existence.

Now Cao Jun is fortunate to be the first to experience it, which is really a great luck, of course, more unfortunate!

Zhang Xiu is not a fool, seeing that the "hot oil" works so well, he finally understood why when it was distributed to him before, Mi Zhu repeatedly told him not to use it as a last resort, and immediately his face changed, and he shouted: "Quick, save the rest and save it for later critical moments." ”

Under the city, the shouts of the burned Cao soldiers gradually stopped, turning into a charred corpse, and the remaining Cao soldiers also hurriedly retreated. Zhang Xiu, who was overjoyed, did not take the opportunity to release arrows to expand the results of the battle, otherwise there would be more casualties.

Li Ru also saw for the first time that "hot oil" had such a great achievement, and his heart was shocked: this is definitely not hot oil!

Li Ru was about to speak, but suddenly felt that something was wrong, because the movement of the city wall was no different from when Cao's army was attacking the city, the question was-

Cao Jun is now retired! So what is this?

Li Ru's heart suddenly crossed an idea, and he hurriedly rushed down to the city and checked the vats one by one, but found nothing.

Does it feel wrong?

With this in mind, the sun gradually went down.

Zhang Xiu didn't know what the hell Li Ru was doing, but Jia Xu was also like this before? Yes, Zhang Xiu didn't think much about it, and beckoned his subordinates to hurry up and tidy up the battlefield. It's just that in the end, Zhang Xiu got a bad news-

"General, although we will repair the city wall every day, but Leping is really too small, and the materials used to repair the city wall are really different from our own place, and now the city wall has been damaged by two percent, which is still the result of repairing it tonight."

"What?"

Zhang Xiu's face sank, and said, "You mean that if it goes on like this, the city wall will collapse in ten days and a half months?" ”

The baggage officer shook his head, and said even more irritating words under Zhang Xiu's slightly soothing complexion: "General, this is not the case, now the materials for repairing the city wall are no longer enough. According to the current situation, there is one day left, and it will be exhausted, which means that the city will fall in three days at most. ”

"Three days? Up to one day! ”

Without waiting for Zhang Xiu to get angry, Li Ru walked in, his face was very solemn.

"What do you mean?" Zhang Xiu was puzzled when she heard Li Ru's previous words.

Although no definite evidence has been found, Confucianism is sure that Cao's army is going to dig up the walls of Leping and then attack it in one fell swoop. There is still one day left at most, and tomorrow may be the time for the decisive battle! ”

"We need to prepare!"

After Li Ru finished speaking, he looked at the baggage officer and said, "There is no need to repair the city wall overnight tonight, pack up everything, and then have a good rest tonight, once the city is broken tomorrow, we will withdraw immediately." ”

"Yes, Strategist."

The baggage officer was ordered to retreat, but Zhang Xiu said: "Military advisor, is this too hasty?" ”

Li Ru knew that he was actually trying to say whether he was wrong, and he didn't explain much, but said: "The impression left by the Ming army on the people of the world is that you are good at the field battle. In fact, it makes sense, after all, we have fought with the grassland a lot of times, they don't have any cities, so there is no way to talk about city battles, and most of the army is cavalry, so in fact, our strength is limited in the city. ”

"Now that Leping can't hold on, why don't we just take the opportunity to withdraw, leave this mess to Cao Jun, and then contain it here."

Zhang Xiu actually felt a little aggrieved these days, hearing this, where did he not understand that he would have the opportunity to show his skills next, how could he say more, and hurriedly ordered the generals to prepare.

Li Ru was careful, and when he thought of Zhang Shao, he made another arrangement, otherwise......

"Liaodong Zhang Yide is here, who dares to come to fight?"

Thinking of this guy with a loud voice, Li Ru couldn't help but tremble.

Next.

Cao Jun came again.

Since Li Ru made a discovery first, after taking a closer look, he really made him discover the difference.

"General, look over there, Cao Jun is ready to attack the city."

Zhang Xiu followed Li Ru's hope, saw that it was true, nodded, and said quite respectfully: "The military advisor is really clever and powerful!" ”

Li Ru smiled lightly and said, "Where, if it weren't for Ming Gong's telescope, even if it was really like this, we would have discovered it by secret method now." ”

"That's right!"

Zhang Xiu agreed with the words when he heard this, and looked at the telescope in his hand with a little more reverence, so it is needless to say who it is for.

"Kill~"

As he spoke, Cao Jun had already attacked again. Although Cao Jun's conspiracy has been discovered, Zhang Xiu and others also plan to lose this opportunity to bring more casualties to Cao Jun. The defending side always has more advantages than the besieging side, isn't it?

Let alone......

After only a few moments of Cao Jun's fierce attack, Zhang Xiu saw that the corner of the city wall on the left began to shake, and then "boom" collapsed neatly in just a few blinks.

"General, withdraw!"

"Hmm!"

Zhang Xiu, Li Ru and others gave an order, and the prepared Ming soldiers huraled down the city wall, before the Cao army rushed in. Evacuate according to the scheduled plan.
