readx; The attack was launched at the same time at the four gates of the Roman city, tens of thousands of Han soldiers rushed to the city head at the risk of death under the cover of bows and crossbows, and the attack on the south gate was the most violent, all the ladders and chariots of the Han army were concentrated at the south gate, and even the cavalry was used, using cavalry to attack the city, and the sound of horse hooves and war drums covered the sound of digging tunnels outside the city, which made Caracalla more convinced that the main direction of the Han army's attack was the south gate, and the other three gates were just feints.

Caracalla couldn't wait to mobilize the main force of the Qin army to the south gate, although the Han army changed the main attack and feint attack many times in yesterday's battle, but the Roman city wall is strong, Caracalla is not worried that any wall will fall in a short time, he has time to readjust the deployment, just like yesterday, however, Caracalla still gathered heavy troops to the south gate, just to prevent the Han people digging tunnels,

Most of the soldiers transferred to the south gate were concentrated on both sides of the trench, holding giant axes and broadswords and staring nervously at the trench in front of them, for fear that the Han soldiers would jump out of the tunnel coldly.

More than half an hour passed, and suddenly there was a strange horn sound outside the city, and the Han soldiers who were still violently attacking the south gate of Rome just now went down like a tide, and even those ladders and chariots used for siege were abandoned.

Caracalla stood at the head of the city, watching the Han army retreat, full of suspicions, if the Han army changed the direction of the main attack, it would only reduce the intensity of the attack, but it should not withdraw the army, and the retreat was so complete that the infantry retreated to the back of the cavalry,

The Qin army does not have such a treasure as a clairvoyant mirror, and even if there is, the dust raised by the galloping of the war horse completely obstructs the line of sight, however, although Caracalla can't see the movement of the Han army clearly, it does not prevent him from reasoning, thinking of yesterday's discovery, Caracalla concluded that the tunnel of the Han army is nearing completion, and the retreating siege troops are preparing to enter the tunnel and sneak attack Rome, and these cavalry are galloping back and forth in order to continue to cover up the sound of digging tunnels,

Caracalla immediately ordered: "Release the water." Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

It turned out that after a night, Caracalla came up with an excellent way to deal with the tunnel, that is, to fill the trench with water, as long as the Han army dug the tunnel, the water would pour in, drowning all the Han soldiers inside, although there was no decent pond around the trench, and there was no small river to divert water, but Caracalla had his own solution,

The city of Rome was one of the largest cities in the world at that time, in addition to 200,000 troops, there were more than 1 million people in the city, Caracalla gathered more than 100,000 young men on both sides of the trench, each prepared two buckets full of water, and waited for him to give an order, then poured water into the trench, the reason why the trench was not filled with water in advance was because Caracalla was worried about being discovered by the Han army, and lost this great opportunity to hit the Han army,

At this moment, the Han cavalry galloping outside the city also began to retreat, the sound of horses' hooves became smaller and smaller, but the fine work under the city wall did not hear the sound of the Han army digging tunnels, which made Caracalla puzzled, could it be that the Han army was still waiting for the opportunity,

Suddenly, Caracalla heard a loud noise, and then the whole earth seemed to tremble, and before Caracalla understood what was happening, he felt his feet loosen, and the strong Roman walls collapsed in an instant, and Caracalla, who was standing at the head of the city, also fell down with a large pile of rubble, and could not stand up again.

It turned out that Liu Xin didn't plan to dig the tunnel into the city of Rome at all, but only dug under the southern wall of the city of Rome, and then used a secret weapon, gunpowder,

In fact, the research institute has long produced gunpowder and improved it, but since then, the role of gunpowder is only limited to the production of fireworks and firecrackers, Liu Xin also thought about producing artillery and muskets, but due to the limitation of the smelting level, the guns produced are prone to explosion accidents and are not able to be used at all, however, this expedition to Daqin, Liu Xin still carried a large amount of gunpowder in the army,

This time, because the city of Rome is too strong, even the trebuchet is difficult to shake, Liu Xin had a whim, want to try to test whether the gunpowder can blow up the city wall, when the tunnel dug under the southern wall of Rome, the gunpowder was also buried in, because there was no fuse, in order to ignite the gunpowder, some soldiers volunteered to act as daredevils, with a loud bang, even if these soldiers were not killed on the spot, they were all buried in the collapsed tunnel, there was no possibility of survival,

It was with the sacrifice of these soldiers that the entire southern city wall of Rome collapsed, not only the defenders at the head of the city suffered heavy casualties along with the collapse of the city wall, but even the Qin soldiers guarding the side of the trench and the young men who poured water into the trench were also buried alive under the ruins in an instant, and there were few escapes.

The cavalry of the Han army, which had retreated, shouted in unison, braved the dust and smoke from the collapse of the city wall, and rushed into the city of Rome, which was broken.

However, the ensuing battle was not easy, there were more than 50,000 Qin soldiers killed because of the collapse of the city wall, plus the Qin soldiers who died under the trebuchet attack, 80,000 Qin soldiers had been killed, but the remaining more than 100,000 Qin soldiers still resisted stubbornly and refused to surrender, and launched a fierce and brutal street battle with the Han army, the whole battle lasted until the evening, and gradually subsided, the city of Rome was full of corpses of soldiers on both sides, and the air was filled with a disgusting smell of blood,

After the Han army paid more than 20,000 casualties, it finally took full control of the city of Rome, and the remnants of the Great Qin army no longer resisted, but threw away their armor and hid in the homes of the people. As long as those suspected of being soldiers are found to be executed immediately, many innocent people are also killed.

Liu Xin still kept a clear head, and immediately ordered the rectification of military discipline, Rao is so, nearly 100,000 people in the city of Rome have been killed by angry Han soldiers, these soldiers were supposed to be punished by military law, but Liu Xin took into account their feelings, and after all, they killed the Great Qin people, and it can be regarded as avenging the innocent dead merchants, so he pardoned them,

However, Liu Xin was not so kind to the high-ranking officials and nobles of Great Qin in Rome, and their property would be confiscated to make up for the losses of the Han army in this siege.
