When Qin and Jin left Persepolis, they took with them a large number of exquisite and ancient artifacts from the Persian Empire, which Zamas brought back to Chang'an as a tribute gift.

Qin Jin temporarily had reservations about Zamas's change of attitude, and sent a special letter to Hilfan to Zheng Xianli on this matter, telling him to pay attention to Zamas's movements in Persepolis and show no mercy once he found a problem.

These were all explanations he made as much as he could before leaving Persia, and the plan to attack Persia was a long and difficult process, which was inseparable from the long-term strategy of coordinating the overall situation, and also inseparable from everyone's dedication.

Qin Jin had never felt reluctant to leave a certain place, but he couldn't help but hesitate a little when the return date was getting closer and closer.

The 5,000-strong cavalry escort headed northeast towards the city of Mulu, which was on the eastern edge of Khorasan. Abbas had set up his satrapy in Mulu City, with the main purpose of conquering the Transoxiana region and Tochar, which had been in turmoil for hundreds of years.

Nowadays, it has been placed under the control of the Tang soldiers, and this thousand-year-old city has also become a military center of the Tang Dynasty to control the east and west.

At present, the person in charge of guarding this place is Qin Yan, who sent troops through Tubo, and the Tubo soldiers are brave and good at fighting, and most of Qin Yan's troops are recruited from the Tubo warriors, since the city of Luo was sent by the Tang Dynasty to send troops to station, this plateau regime that has repeatedly challenged the majesty of the Tang Dynasty has completely fallen into a cycle of worshipping the strong.

The nobles in the city of Luo fell to the ministers sent to Tibet by the Tang Dynasty, and Zampu's former cronies were all purged from the center of power, and many recalcitrant people were even killed or handed over to the Tang Dynasty for disposal.

Qin Yan learned that the prime minister was about to return east, so he rushed hundreds of miles in advance to greet his former head of the family.

A few days later, Qin Jin arrived in Mulu City.

The old city wall of Mulu City was almost completely destroyed by artillery in last year's battle, and after less than a year, most of the reconstruction work of the city wall has been completed, and the construction schedule is much faster than expected.

Only then did Qin Jin discover that Qin Yan not only had an outstanding talent in military affairs, but also had some ability to be responsible for general government affairs.

Looking at Qin Yan with a beard on his face, Qin Jin secretly sighed, this guy's growth rate has exceeded expectations, the guy who could fight and frequently make trouble has now grown into a general who can take charge of himself.

In front of Qin Jin, Qin Yan took off his cold mask on weekdays, as if he had never left the Shenwu Army's Zhonglang General's Mansion, and personally ran before and after, pouring tea and water.

"Qin Yan, you are now the general of the town guarding side, you don't have to do everything yourself here with me!"

When Qin Jin said this, he naturally took into account Qin Yan's prestige in the army, and didn't want people to associate him with a nodding and stammering person, which would hurt him a lot.

But Qin Yan opened his mouth and smiled:

"No matter what time I go, I'm the dog of the Zhonglang General's Mansion......"

Seeing that he was so stubborn, Qin Jin no longer insisted, and then talked about important military and political affairs.

Qin Yan picked up the important personal report and asked with great anticipation when he could return to Chang'an. He learned that the prime minister was about to return east, so he naturally planned to join the ranks of the guards and return to Chang'an, which had been absent for several years.

However, Qin Jin had no intention of letting Qin Yan return to Chang'an in the short term, including the selection of ministers stationed in Luoqicheng had also been reformulated. Qin Yan's new mission was to defend Mulu City and consolidate control over the Hezhong and Tocharian regions.

Geographically, Mulu City is more suitable for controlling these two areas than the four towns of Anxi.

After all, the troops sent through Anxi had to cross the desert and cross the green mountains, and the long-distance attack could only make the Tang soldiers tired.

Mulu City, on the other hand, was originally one with those two regions, which is why Abbas tried to control the Middle River and Tocharian in the first place, and used it as a foundation.

When Qin Yan learned that he couldn't return to Chang'an with Qin Jin, he felt a little depressed, no matter how he grew up, after all, he was still young, and even if he was in his early twenties, there was a limit.

"The dog is willing to escort the general back to Chang'an together, and Mulu City will be handed over to Zheng Xianli or Jiang Fengxiang to guard the town to ensure safety!"

Qin Yan has always called Qin Jin a general, even though Qin Jin is already a prime minister. Because when he left the Qin Mansion and broke away from slavery, Qin Jin was still a lieutenant general in the Shenwu Army.

"No, they have all taken on their own missions, and there is no one to replace them except you. Moreover, in addition to the rivers and Tochar, there is also India further south, where there were once many princely states, and it can form a country of its own for tens of miles. When the imperial court visited this place, it was inevitable to invest a lot of manpower and material resources. There is also the homeland of Persia, whose status is no less than that of the four towns of Anxi, Mulu City is located between many important places, it is really a hub town, you have more courage than anyone else, you know? Be prepared to stay for a long time, at least ten years!"

At present, in controlling these newly conquered lands, the power limit of the local general is not the first place, and long-term peace and stability is the last word, and he is not afraid to cultivate local warlords.

Even if the Metropolitan Governor made this kind of governor have no time limit for the time being, the governors and governors sent by the imperial court have a time limit.

Qin Yan's frustration was clearly written on his face, and even a smile could not hide his disappointment.

"I haven't returned to Chang'an for ten years, I'm afraid I have forgotten my native accent, and now I even speak with the pepper smell of the Persians!"

Seeing that Qin Yan still had the heart to tell jokes, Qin Jin couldn't help but smile.

"Stay with beautiful women and gold and silver, you can choose, isn't being the emperor of the soil happier than being a kowtow insect in Chang'an?"

These were originally jokes of the servants in the palace when Qin Jin was the lieutenant general of the Shenwu Army, but when Qin Jin said it, Qin Yan suddenly felt a little hot on his face.

I just don't know how Qin Jin learned about their private ridicule.

In order to deflect this embarrassment, Qin Yan took the initiative to ask about the offensive against the Lianghe region of the Great Food, which was the core area of the Black-clothed Great Food, roughly equivalent to the Guanzhong region of the Tang Dynasty.

Qin Jin did not hide that he had formulated a strategy before, and briefly introduced the plan to support Khazar, Zamas and others to fight against Mansour's Ctesifon court.

With the current strength of the Tang Dynasty in the homeland of Persia, it is not suitable for a decisive battle with the black-clothed food.

When it came to the decisive battle, Qin Yan was a little eager to try.

"On the day of the decisive battle, the dog is willing to lead the army to attack Ctesiphon!"

Qin Jin smiled:

"If there really is that day, I will be waiting in Chang'an to drink your celebration wine!"

But he changed his words and said:

"Your main task is not all in the West, it is the consolidation of the large land between Khorasan and Ansi that is the most important thing!"
