The Romans inherited a lot of advanced civilization and technology from ancient Greece, although some of them have been lost in the long history, but there are still many advanced scientific ideas that have been handed down and carried forward.

I really don't know how the ancient Greeks came to the forefront of the world in many aspects of science and technology, and Lu Bu even suspects that a future scientist traveled to Greece.

In short, the formula of gunpowder, iron-smelting technology, and the power of water were transmitted to Rome, as if to awaken the memory of Roman scientists, who quickly imitated and modified a lot.

Lucis saw that the Roman legions and auxiliary legions on his front and left flanks were stubbornly resisting the Han army, but the auxiliary legions had no firearms, and suffered great losses in the battle, suffering heavy casualties.

The regular armies of Rome could withstand the attack of the Han army, and the combat strength of the two sides was similar.

It's just that the number of regular legions in Rome is too small, and the number of legions in one of them is only equivalent to a brigade of the Han army.

Lucis felt the need to advise the emperor and the senate to expand the regular army of the Roman legions, at least during the war against the Han Dynasty, especially to make the senators of the Senate face up to the strength of the Han army.

More and more of the Sabbaters on the right flank of the Romans turned and fled, and Marcus reminded his commander, "Lord Lucis, the Sabbatarians are about to collapse, and our right flank is about to be exposed, so let's withdraw our troops back to the city, and use the strong city to stop the Han attack." ”

Lucis nodded, "These incompetent Stubbaters have wasted their firearms, and they might as well be used by those slaves of our auxiliary legions!" “

"Let the cavalry of Macrinus go to meet the Sabbatarians, protect our right flank, and we retreat!"

The horn of withdrawal sounded, and the Roman army, which was fighting fiercely with the Han army, immediately raised their big shields, covered each other, and began to break away from the battle with the Han army, and withdrew to the city of Damgan in an orderly manner.

When the resting people heard the clarion call to retreat, they immediately turned around and retreated in a panic, even forgetting that there were Han muskets aimed at them on the other side.

Many stupid people who leaked out of their backs received bullets from the Han army as they wished, and their corpses were scattered all over the field.

The chaotic retreat caused more casualties among the Sabbators than they had all suffered in the previous shoots for so long.

The Han army shot and chased after the rebels, but was soon blocked by prepared Roman cavalry.

When the Han cavalry received the news and rushed up, the Roman cavalry had already covered each other and retreated to the city of Damgan.

The Romans were still well trained, and even when they retreated, they were in good order, with a few regular legions, left at the end, facing the Han army, retreating backwards, always aiming their guns at the pursuing enemy.

And they will let the auxiliary legions without muskets withdraw first, and their main legions will remain behind the rear hall.

The Roman mortars were also firing shells to stop the Han pursuit.

Eventually, the Roman army and the Sabbatarian army were able to withdraw to the city of Damgan, and the Romans suffered nearly 20,000 casualties, including those of the auxiliary legions.

The Sabbatarians suffered heavy losses, nearly half of the 60,000 men who went out of the city to fight were wounded, and probably half of them were shot in the back while retreating.

Lü Kang did not take advantage of the situation to attack the city, and the casualties of his own troops were not small, and they were even more tired.

The Han army suffered more than 20,000 casualties, but fortunately, the medical level of the Han army was very high, and many of the minor wounded would quickly recover and return to the battlefield.

Most of these casualties were inflicted by the Romans, and as for the resting of the rebels, it is not to mention.

All the senior generals of the Han army held their regular summary meeting immediately after the war, at which the division commanders and brigade commanders who participated in the war all expressed their views.

This time, he was engaged in a full-scale battle with the Romans, and fully appreciated the quality of the Romans' professional soldiers, who made reasonable and effective use of their own advantages and tried to avoid their weaknesses.

Even the auxiliary legions of the Romans, because the officers were all Romans, had a higher tactical literacy than the Rest of the Rebels, but the equipment was backward.

Now that the Romans can even imitate mortars, it seems that the war is going to be protracted.

Lu Kang looked at Guan Zheng and Sima Yi, these two military divisions had to come up with some good ideas.

Sima Yi thought for a while, got up again and looked at the large map, he turned to look at the chief officer of the Ministry of Intelligence in the Rest Empire, "Does the Ministry of Intelligence know the location of Artaban IV?" ”

The official of the Ministry of Intelligence replied simply: "Aldaban IV is in Ctesiphon, and he is busy pacifying the opposition forces in the country. ”

Sima Yi nodded, "Then how many troops are there around him?" ”

"Not much, about 30,000 people, and the main force is in Damgan."

"So is there only one way from here to Ctesiphon to Dhamgan?" Sima Yi continued to ask.

The intelligence officers also came to the large map and looked at it carefully, which was drawn by the cartographers of the Ministry of Intelligence over a period of several years, taking advantage of their legitimate business travel status.

Now the caravans of the Han Dynasty have reached the mainland of the Roman Empire, the Italian peninsula, from the Silk Road on land, and soon, a map of the Roman Empire will be drawn.

The official of the Ministry of Intelligence carefully checked the map and pointed to the bottom of the map, "Master Hui, go south from Dhamgan, pass through Isfahan, and reach Ctesiphon from the southern Persian-controlled region of Persis. ”

"However, this route needs to pass through areas controlled by the Persians, who are independent of the royal family of Dormition, and the Persians have been making a lot of noise about independence in recent years."

"In particular, I heard that the newly rising Persian leader was called Ardashir, and he killed all his brothers who were not competing with him for the chieftain, and not only occupied Posis, but also occupied nearby Isfahan, Susa, and other places, and his power expanded greatly."

"Persians? Ardashir? Sima Yi thought twice in his heart, he looked at Lu Kang, "His Royal Highness the Prince, I think that since Dhamgan is deadlocked, we might as well find another way, go deep behind enemy lines, and attack Tessifon." ”

After all, Lu Kang was young, and he vigorously agreed with Sima Yi's idea of being full of adventurism, and even wanted to lead the army himself, but Fa Zheng hurriedly stopped it.

"His Royal Highness the Prince, you are the prince of the Han Dynasty, the body of ten thousand gold, you should not personally risk this kind of dangerous action." Fa Zheng stopped the way, and Lu Kang couldn't help but listen.

Because it was true that Lü Bu appointed Lü Kang as the commander of the expeditionary force, but there was also a holy decree for Fa Zheng, who had the right to succeed the crown prince Lü Kang as the commander of the expeditionary force after his improper command or accident.

In the end, the important task of this long-distance journey still fell on Ma Chao and Sima Yi, because borrowing from the Persians, this kind of social work is still Sima Yi's strength.
