The topography of the Indochina Peninsula is often low mountains and hills, and Shanluo Castle is built between the 100-meter-high mountains.

Shanluo City has a history of seventy or eighty years, and the ruined Jiaozhi Li Dynasty chose to build a city here in order to defend against the Zhenla Empire, which was fighting against each other.

Hearing the news that the Zhenla Empire was coming to attack Shanluo City, Li Nan transferred a large number of craftsmen to carefully strengthen the city walls and gates, after all, if the city could hold on for a while, it would kill and wound more enemies.

There are not many ways to attack a fortified city, but there are two ways, inside and outside.

Now Li Nan is personally in charge of the city, and it is difficult for foreigners in Zhenla to get in, so there is basically no chance to break through the city from the inside. And the tactics that the Zhenla Empire can adopt at present are nothing more than a strong attack.

Obviously, the appearance of trebuchets is the first step of the Zhenla people, but they are not qualified to play long-range attacks with Li Nan.

The Chinese began to use trebuchets during the Spring and Autumn Period and the Warring States Period, when the Zhenla Empire did not even have tribes.

In the Northern Song Dynasty's "Wujing General Essentials", there are more than a dozen types of trebuchets. It is roughly divided into three categories: light, medium and heavy. The light one is operated by two people; Dozens of them; As for the heavy ones, they are as high as several zhang, and they need 100 catties of stone bullets to operate.

Although the Song people made some improvements to these trebuchets, there was no breakthrough in technology. The main drawbacks are that there are multiple people and the limited distance of the stone.

It doesn't matter if Li Nan doesn't understand these devices, because he has a large number of followers, and these outstanding talents from other worlds have certain areas of specialization.

Tyrion, a little demon from the world of ice and fire, and Sienna, the deputy commander of the Cobra unit in the high-tech world, have all studied various weapons of war. After their guidance, the craftsmen hastened to research and improve the existing trebuchet and added counterweights. This eliminates the need for manpower to carry out the projectile and greatly increases the distance of the projectile.

Before the hundreds of trebuchets of the Zhenla people were assembled, gray-white clouds floated from Shanluo City.

No matter inside or outside the city, everyone stopped their movements and looked up, only to see the cloud floating rapidly towards the Zhenla army, and then drew an arc, and smashed down with a whistling sound that broke through the air.

The trebuchet, which had already measured the distance, accurately hit the trebuchet position of the Zhenla people with a boulder, and the hundreds of siege equipment that the Zhenla people had finally transported from their own country were smashed into sawdust in an instant.

The boulder jade that fell from the sky spread to the nearby Zhenla soldiers and war elephants, needless to say, people will die when they touch it, and they will be injured if they are rubbed, and it is the best result not to be smashed into flesh, and even those war elephants wearing heavy armor have been stoned to death.

After two rounds of trebuchet attacks, all the trebuchets of the Jinla people disappeared, and only a pile of broken wood residues remained in front of the battle.

The fact that the Zhenla people were not able to make a large number of trebuchets in a short period of time, and the fact that they were frustrated just after their arrival made the lord of Zhenla, who was in the Chinese army and was closely protected, angry, and he immediately issued an order to forcibly attack the city.

If the army of war elephants of the Zhenla Empire charges up in the gentle area, no army can stop it, and it is also an invincible existence in the whole world. Even in the later generations of advanced technology, only armored tank clusters could hedge against them.

It seems that the order of the lord of Zhenla is stupid, but it is not.

No matter what tricks and magical weapons Li Nan has, he is very pale and powerless in the face of the absolute strength of the 160,000 armored war elephants and more than 200,000 elephant soldiers and elephant slaves of the Zhenla people.

The first wave of 3,000 elephants acted as the vanguard, and after running and accelerating, they rushed towards the city, and all the trebuchets in the city began to throw gunpowder bombs.

After the explosion of gunpowder, many war elephants and soldiers were indeed killed, and the earth-shattering explosion also made some war elephants frightened and crazy, but there were too many enemies, and the frightened war elephants were wrapped in and continued to rush towards Shanluo City, and the elephant soldiers sitting on the elephant bowl also shot arrows at the head of the city.

When both sides were in range, the three-eyed firearms, crossbows, and grenades on the city wall rained down on the Zhenla people, and the heavily armored war elephants had thick skin and tenacious vitality, and as long as the fatal points on their bodies were not hit, they still charged wildly.

Siege warfare is a tragic war of attrition, and at this moment, every minute and every second is a loss of life......

In less than an hour, the fierce battle was over, and the Jinla people lost 3,000 war elephants and all the elephant soldiers, and none of them survived.

In addition to being shot dead by elephant soldiers, Li Nannan did not have much damage in terms of personnel, but the intention of Zhenla Kingdom had been achieved, and the first gate of Shanluo City was broken by the mad war elephants.

Originally, there was only one gate, and this standard gate was made of heavy wood that was more resistant to corrosion on the inside, and then wrapped in copper and reinforced.

After Li Nan decided to resist the Zhenla army again, he ordered two more gates to be installed, one made of ironwood as strong as steel, and the other as thick as an arm.

The lord of Zhenla used the 3,000 war elephant army as cannon fodder for the temptation, and broke through a city gate, which is not a good thing.

The lord of Zhenla, who had a huge bargaining chip, did not intend to give Li Nan's army any respite, and when he tested the number of troops that could be accommodated on the battlefield and the strength of the enemy's attack, he began to attack in batches of three thousand war elephants.

This fierce battle between the two countries was fought from the afternoon to the setting sun, and from night to dawn, and by the afternoon of the next day, the victory or defeat was about to be decided.

The last steel fence gate was still there in Shanluo City, and the other two gates were breached, and now a large number of soldiers armed with crossbows with divine arms were hiding behind the gates to shoot.

The corpses of dead elephants and elephant soldiers brought a lot of trouble to the Zhenla people, and they could only let those elephant slaves drag the corpses away from the battlefield at any cost, so that the follow-up troops could charge.

Seeing that victory was in sight, the Zhenla people began a new round of attacks, and it is estimated that this will be the last.

"The hosts! Let's get back in the back! Dorcott estimated that the last gate would soon be untenable, so he quickly suggested.

Li Nan looked in the direction of the city gate, rode onto the war horse and asked in a deep voice, "Is the city ready?" ”

"According to the design of Tyrion and Sienna, it is all arranged."

After getting a satisfactory answer, Li Nan nodded and galloped towards the official residence in the city with a large number of guards.

"Boom!" The Zhenla army, which did not care about casualties, finally broke through the last iron gate of Shanluo City, and countless war elephants and elephant soldiers poured into this mountain city.

Li Nan, Tyrion, and Sienna stood on the high guard tower that had been erected in the mansion and observed the battle in the city with binoculars.

At this time, the small city of Shanluo was full of shouts of killing, elephant roars, and explosions of grenades and firearms, and there were two sides of men fighting in every street.

Li Nan and his followers had long known that the city gates would not be able to withstand the Zhenla army for long, so the houses in the city had long been demolished and dilapidated, and the streets were either piled with a large amount of earth, stone and wood, or deliberately dug out large pits to limit the pace of war elephants.

When the Zhenla people lost the charge advantage of the war elephants and began to engage in street battles with Li Nan's army in the city, their casualties began to rise sharply......
