The Sassanid king Ardashir I quickly assembled a large army and led it to the city of Susa, where he prepared for a decisive battle with the Han Chinese.

However, the Han people cowered in the city of Susa, and they had to surround Ma Gui and others first; However, they were mainly heavy cavalry and hoplites, and the combat effectiveness of light infantry was not strong, and the Sassanid army tried to attack the city several times, but was attacked by Ma Gui and others and suffered heavy casualties.

The Sassanid Empire used a giant battering ram that arrived later, and was killed by a large bed crossbow, and the trapping officers and soldiers then burst through the city gate and set fire to the battering ram.

This gave the officers and soldiers of the Sassanid Empire a glimpse of the great fighting power of the Han Chinese officers and soldiers, and the sharp arrows fired from the bed crossbow exceeded the javelins they used, and the power was so great that any heavy equipment in front of it was easily torn apart, and it did not play the slightest protective role.

Ma Gui and others could not hold out, leaving the Sassanid army helpless; Gao Shun lacked heavy cavalry, so he asked Ma Gui to avoid a head-on battle with the Sassanid Empire, and only need to contain it, and now it seems that the strategy of not sending cavalry, but defending himself with infantry is very correct.

Seeing the powerful heavy cavalry, elephant soldiers and hoplites of the Sassanid Dynasty outside the city, Ma Gui and the others secretly rejoiced, fortunately they learned about the military strength of the Sassanid Dynasty from the Kushan Empire in advance, and adopted conservative tactics, otherwise they would have suffered a crushing defeat or heavy casualties if they attacked rashly.

However, Ma Gui and the others were not discouraged and were actively thinking about ways to break the enemy.

In the end, Ma Gui came up with a way, he remembered that when fighting against the Funan Kingdom, they also dispatched elephant soldiers, but they were easily defeated by the local lieutenant using fire attack, and even when the elephants were afraid and angry, they rampaged in the formation of the Funan Kingdom, causing huge casualties among their own officers and soldiers, and he was ready to use this method to deal with the army of the Sassanid Kingdom.

Since the Han people held on to the city and did not fight, the officials of the Sassanid Dynasty thought that the Han people were afraid, and their mood gradually relaxed.

Ma Gui chose a dark night, sent senior cavalry, and fired a large number of rockets into the Sassanid camp, and the heavily armed officers and soldiers of the trapped camp responded.

The climate here is dry, and the rockets ignited the enemy's tents, vehicles, food and grass and other materials, and the fire spread in the camp.

Due to the fact that late at night, the officials were asleep, and the Sassanid officers and soldiers were too lax to organize an effective fire extinguishing in a short time.

As the fire spread, as Ma Gui thought, the elephants were frightened and fled in all directions, unable to control it; Elephants broke through fences, broke tents, and caused a large number of soldiers to be killed and wounded, adding to the chaos in the barracks.

However, their armies were stationed in divisions, and the damage caused was only to the officers and soldiers in some areas, and did not harm the foundation of the Sassanid Empire.

Ma Gui not only has the highest force value, but also has the highest intelligence among the people.

Through this sneak attack, it was not possible to inflict fatal damage on the enemy, but Ma Gui gained an important message from it, the heavy cavalry and heavy infantry of the Sassanid Dynasty were not always ready for war, and after withdrawing from the battlefield, they would also take off their heavy armor and rest, and only equip themselves and their horses with heavy armor before the battle.

This is similar to the officers and soldiers trapped in the camp, but he didn't need to pay attention to it before, otherwise, he would wear heavy armor weighing dozens of catties at all times, and no matter how strong his body is, the officers and soldiers will be tired and unable to maintain strong combat effectiveness in wartime.

Ma Gui spoke his mind and prepared to attack the enemy camp again.

Sun Cheng was the most cautious and objected: "This law is not appropriate, we still act according to Your Majesty's plan, our purpose is to contain the main force of the Sassanid Dynasty, let Meng Wen and others make contributions outside, weaken the war potential of the Sassanid Dynasty, hit the reputation of the Sassanid Dynasty, and affect the confidence of the nobles in the Sassanid King. ”

Ma Gui thought for a while, adopted Sun Cheng's suggestion, and stayed and waited for the time being.

Li Qiang first led Sestan near Kandahar, Afghanistan, as a base for advancement.

Later, along the valley to the northwest, he conquered the city of Nisa, a military town that was a great city to defend against the nomads of the north and east. Here, the war leader also has the intention of guarding against the Kushan Empire's southward expansion.

The army then turned southwest, led Margiana, and entered the core area of what would become Iran.

Here, due to the lack of external threats, a large number of nobles developed, they occupied a place, implemented a hereditary system, accumulated a lot of wealth over the years, and finally cheapened Li Qiang and others.

Li Qiang found that the resistance encountered was very small, and there was no strong army in the local area, so several of them scattered to plunder, sweeping all the way to the south.

Wherever you go, you will become a hell on earth.

Li Qiang and others were unrelenting to what they considered to be barbarian peoples, and only by exterminating the aborigines could those lands be completely owned by the Han Chinese.

The old and the weak were killed; Young and strong are slaves.

Women, on the other hand, will become machines for the reproduction of officers and soldiers, expanding the local population of the Han Chinese, who would otherwise be only a minority.

Gao Shun didn't need to follow, their targets were mainly in big cities and district-level places, and many villages still had fish that slipped through the net, but they had little influence and were not to be feared, and they would become the main body of paying taxes for the imperial court in the future.

Li Qiang's brutal killing, the news came, which shocked the Sassanid Dynasty, such a killing, even if they defeated the Han Chinese, they would be a general, easily destroyed by the Romans, and the consequences would be even worse.

So, the Sassanid king sent emissaries to negotiate with Ma Gui and prepare for reconciliation.

Ma Gui did not receive Gao Shun's request for negotiations, and he had only one goal, that is, to completely destroy the Sassanid Dynasty and the local ethnic groups and religions, so he negotiated with the envoys.

The messenger asked why they had attacked their country and killed their people.

Ma Gui retorted: "As a vassal of the Han people, the Anxi Empire is friendly to the Han people, and often sends people to pay tribute, but it is suddenly destroyed, how can the Han people stand idly by?" and will avenge it. ”

The messenger said, "We can send a princess to marry your country, marry well, and continue to pay tribute to your country!" ”

Ma Gui scolded: "The current king is only a small local nobleman, killing the king and seizing his country is disloyalty, unrighteousness, and a great crime. ”

The messenger could not refute it, so he said, "But the people are not guilty, why do they kill them?" ”

"Whoever dares to be loyal to the king is regarded as an accomplice, and his sin will not be forgiven!"

The peace talks broke up unhappily, and the envoy returned in a huff.

At this time, Gao Wei led the fleet to come again, but learned that the city of Susa was besieged and they could not enter the city, so he led the fleet south and opened up another battlefield.

They returned to what would become the Strait of Hormuz, landed on the southern shore, and destroyed several small kingdoms there.

The kingdoms of Himyar, Hadaramaut, and Miskar, all of which were established by the Arabs in the southeast of the Arabian Peninsula, were also among the countries and nations that Gaoshun must destroy.

At this time, they were still in a very backward stage, and they were all easily destroyed.

When the Sassanids learned of the purpose of the Han army, their subjects were shocked; When they learned that the Han people still had reinforcements, they were even more frightened.

The prestige of the Han people was stronger than that of Rome at that time.

At this time, Gao Shun was very happy, because he had led so much territory, and the system area had exceeded 25 million square kilometers, ushering in another upgrade.
