At dawn the next day, Sima Bi, who had suffered a great loss under Yao Yu, became angry and surrounded 40,000 people in Runan City.

An order was given, and the city was ready to be attacked.

As Quan Yan, who has rich experience in defending the city, seeing this situation, he immediately arranged for his subordinates to prepare rolling wood and stones, hot oil arrows, and prepare for battle.

When Sima Bi's headquarters held high a huge wooden shield covered with raw cow skin and escorted the ladder step by step, Yao Yu, who was watching the battle at the head of the city, did not see any change in his face.

Ladder siege is an ordinary means.

The shield array looked quite exaggerated and incomprehensible, but the real offensive and defensive battle obviously began only when their ladders were built and the soldiers gave up their shields.

Right now, it's just a warm-up.

Immediately, Yao Yu asked his men to save arrows and wait for the enemy to move.

When the ladders rose one by one and pushed towards the city wall of Runan City, Yao Yu saw clearly, and took advantage of the enemy's loss of shield protection, and immediately made a decision and ordered the arrows to be fired in unison.

For a while, the city wall was covered with a rain of arrows.

Under the city, the sound of the arrows screaming one after another, continuous and endless.

Neither side paid attention to this scene, after all, it was just an appetizer before the siege.

In ancient times, it was not so easy to siege a city.

If it weren't for the surrender of the defenders in the city, or if there was a female cadre who opened the city gate, often a city would require both sides to fight for more than a month before it could be separated.

When the cloud ladder was on the city wall and countless soldiers swarmed up, Yao Yu raised his hand and shouted violently: "Do it."

As his order was given, countless hook knives stretched out from the lookout in the middle of the city wall, and they cut off the ladder with just a pull and a pull.

Countless soldiers who climbed the ladder fell down in a frightened look, and with a little luck, they fell into a broken bone and tendon, and those who were unlucky died on the spot.

Seeing this scene from afar, Sima Bi smiled: "This Yao Yu is quite capable. I broke the ladder attack so easily."

It's no wonder that Sima Bi said this, after all, when Yongju was responsible for guarding the city in the past forty days, no one in Runan City came up with the method of using a hook knife to break through the cloud ladder.

Many times, they use hot wood oil to block the ladder offensive.

How could Yao Yu have such an idea and directly cut off the cloud ladder.

"However, this little trick alone is not enough to make Xiao Wang think about you differently. Keep attacking."

When Sima Bi's words fell, the soldiers pushed out siege equipment such as building carts and chariots, on the one hand, to suppress the city guards, and on the other hand, to hit the city gates.

Yao Yu was not in a hurry, and asked his subordinates to take out the rockets they had prepared last night, light them, and attack the enemy's building car.

This move greatly exceeded Sima Bi's expectations.

After all, there is such a thing as a rocket, which has never been used on the battlefield before.

In fact, even in Yao Yu's world, the first time this thing was used was invented by Hao Zhao when he was guarding Zhuge Liang during the Battle of Chencang of the Three Kingdoms.

Rockets are no more difficult to make than ordinary arrows, and the process is more cumbersome.

As early as when Yao Yu was preparing for armaments, he asked Banbiao to secretly make rockets.

This time he came to the rescue of Runan City, and he carried a lot of it with him.

For the wagon covered with cowhide curtain, ordinary arrows and slings did not hurt it that much.

But rockets are different. This thing was soaked in tung oil and wrapped in saltpeter, and plunged into a wooden building car, and there was no strategy at all to deal with it.

The cars caught fire one after another, and the soldiers on the cars were desperate to jump to the ground in order to escape for their lives.

As a result, the end result is to fall into a pulp on the spot.

Not only the building car, Yao Yu also asked people to find the huge stone grinding disc in the city, tie it with a rope, stand on the city tower, and smash the rushing car that hit the city gate.

Just a few hundred pounds of stone grinding discs can be used

Crush the powder that has been carefully made to smash the car.

In this case, even if Sima Bi filled the moat early, there was still no means to approach the city wall or even break the city.

Even, he was busy all morning, and not a single soldier touched the city wall.

This made Sima Bi's face extremely difficult to see.

When he fought against Yong Ji before, his own soldiers might have climbed the city wall and started a white-knuckle battle with the defenders.

It's like today, a morning's busy work, paying more than a thousand casualties in vain, and finally can only look at the city wall and sigh with hatred.

"Sima Bi, listen to my advice, with me here, don't think about breaking through Runan City. It's better to go back early and be your king's son. The province was captured alive by me, and the world laughed at it."

Yao Yu held an iron horn and laughed loudly across the city wall.

Hearing this, Sima Bi was extremely angry: "Yao Yu, you are less proud, let's see!"

After that, Sima Bi ordered the troops to be collected and prepared to attack after lunch.

However, what Sima Bi didn't expect was that Yao Yu would dare to take advantage of this time to fight back.

When the city gate was wide open and hundreds of dead soldiers were killed under the leadership of Yong Ju Quanyan, the front camp of Sima Bi, who was busy lighting a fire and cooking, panicked.

Before thousands of front-line soldiers could pick up arms, they were rushed into the camp by Yong Ju Quanyan and killed them.

When Sima Bi sent Sun Chang to command the Chinese army to support, Yong Quanyan withdrew one step ahead of schedule.

So much so that Sun Chang could only look at the high city wall and breathe fire with his eyes.

He wanted to order his subordinates to attack, but not to mention that they didn't carry siege equipment at this time, so they brought siege equipment in the morning, isn't it the same as being taught to be a man?

The most important thing is that the soldiers have not eaten yet, and it is enough to be tired enough to be able to hold weapons and wear armor.

No, Sun Chang glared at the city wall hatefully, and could only turn around and give the order to retreat.

Looking at Yao Yu again, a sneak attack was successful, which greatly boosted the morale of the defenders.

In fact, their sneak attack did not cause any damage to Simbi, killing no more than 30 enemies in total.

But what Yao Yu wants is this effect, that is, to use sneak attacks to mess with your mentality.

As it turned out, he succeeded.

Sima Pi did go up, and the soldiers had only eaten, and he gave the order to attack.

This time, Sima Bi used a trebuchet.

He's going to get serious.

Hundreds of trebuchets surrounded it on all sides, and on the city wall, the faces of the defenders became a little ugly.

You know, the most terrifying thing about trebuchets is not to suppress the defenders, but to damage the city walls, and no matter how strong the city walls are, they can't stop the repeated bombardment of the trebuchets.

But Yao Yu was prepared.

He ordered the straw curtain that had been prepared the previous night to hang up about a meter from the city wall.

In this way, the damage of the trebuchet is greatly reduced by buffering.

The huge stone smashed on the city wall, and it was not even scraping.
