[The letter to Erfeng was written by the last emperor of the Sassanid Dynasty, Yi Siqi.

As we all know, history has always been rich in unlucky eggs, and Iji is similar.

And his script is too familiar to everyone: the lord is suspicious, the country is suspicious, the external worries are internal, and the power is on the side.

The Sassanid Empire replaced the Resting Empire, and also inherited the contradictions between the Resting Empire and Rome.

Just before Isiqi ascended the throne, the four-hundred-year war between the Sassanid and Byzantine empires came to an end.

Since 613, for this century-old feud, the two sides can be said to have done their best.

Byzantium had Emperor Heraclius personally conquered and found Cossacks and Western Turks as helpers.

The Sassanid Empire increased its treasury with unprecedented taxes and united the Slavs and the Avars.

The end result was a great defeat of the Sassanid Empire, political turmoil, and five emperors in five years, with Isiji being the sixth.

Iji, who ascended the throne in 632, was able to secure the throne not because of his clever means, but because of the emergence of Arabs who believed in the Great Food Religion.

The Arabs attacked both Byzantium and the Sassanid Empire, and four years later succeeded in conquering the Sassanid capital of Ctesiphon, and the Persian Emperor Isai began to flee eastward.

And who is on the east side? The Western Turkic Khanate and the Tang Empire.

Whereas, the Western Turks once helped the Byzantines beat the Sassanid Empire.

Yi Si Ai could only pin his hopes on Li Shimin.

In the ten years from 638 onwards, Erfeng received four earnest distress letters from Isiai, and then Erfeng politely declined four times in a row.

After all, from East Asia to the Red Sea, the distance in a straight line is 6,000 kilometers, and even if you fly back and forth, there are 30,000 miles, and this distance is really impossible in ancient times.

After the death of Yi Siai in 651, his son Belus succeeded him and continued to write letters to the Tang Emperor asking for help.

For the first time, Li Zhi told the truth, it was too far away to help, and there was also the Western Turks.

The Second Western Turks had already perished, and Li Zhi was really annoyed, so he sent an envoy to make Belus the governor of Persia.

In 675, the White Food, which had completely annexed Sasanian, began to invade the east.

Belus took the seal letter from Li Zhi and went directly to Chang'an, and was awarded the title of General Weiwei.

And the mud master that Pei Xingjian asked for earlier was the son of Belus, that is, the current king of Persia. 】

For the ministers of the Ganlu Palace, they will be able to witness the future of the Tang Dynasty sooner or later.

On the contrary, it is this kind of customs and customs that are tens of thousands of miles away, which makes them even more interested.

"In other words, at this time, the heir has not yet ascended the throne?"

Fang Xuanling was full of interest and calculated:

"Hmm...... This should be the time for internal and external troubles. ”

"What can I do?"

Li Shimin stared at Ardashir's name and looked at it, but finally let it go, after all, most of this person had been dead for almost four hundred years.

As for the ridicule of the light curtain, Li Shimin can only say that he is used to it, after all, it is impossible to really drill into the light curtain to beat that Wen recklessly.

At this time, after hearing Fang Xuanling's question, he shook his head:

"The only thing we can do is to clear the Quartet, then Sassanid has a monarch a year at this time, how can an ambitious person be able to resist the enemy because of a word thousands of miles away."

Then his tone was full of envy:

"This big food has become a fisherman's profiteering."

There is one meaning in the words: Why didn't such a good thing happen to me?

Du Ruhui frowned:

"When this Sassanid was not destroyed, this Arabia was still a great food, and when the Sassanid was destroyed, it was called the white food."

"When Xuanzong was in the time of Gao Xianzhi and his fierce battle with Talas, it was also known as the black-clothed food."

"What's the difference?"

There was too little information, everyone could only look at each other, and Fang Xuanling could only barely guess:

"From what he said, it seems that these Arabs all believe in the Great Food Religion, or is it because of this?"

I can only guess first.

Li Shimin vaguely remembered:

"At the time of Talas, the light curtain also said that the black-clothed food was still fighting fiercely with Byzantium, and this Rome had lived so long?"

After all, if this is the case, wouldn't this Roman state have been at least seven or eight hundred years?

Du Ruhui disagreed:

"This Byzantium is to Rome, or like I am to China and China."

"From the perspective of outsiders, isn't my Huaxia Guozuo also a thousand years old?"

This statement was accepted by Li Shimin with a nod.

Then I saw him walk to the map, briefly measure the distance with his hand, shook his head, and said:

"The land route is a moat, and there are thousands of countries blocking it on the way."

The index finger tapped Chang'an again, drew an arc along the Hexi Corridor and the Green Ridge, and then nodded at the Khyber Pass:

"This place is rich, or you can set up a military government to defend against the enemy in the west."

The records of later generations still make Li Shimin's heart itch, a small country in Tianzhu can directly take over 200,000 people's grain and grass without breathing!

The richness of this place may be beyond imagination.

Seeing His Majesty standing in front of the map, he fell into deep thought again.

Li Shichang leaned over to Su Dingfang's side and said with a smile:

"Dingfang lost his beloved apprentice, how do you feel?"

Su Dingfang's face darkened, and he said lightly

"In the eyes of His Majesty, it is all for the country, what's wrong."

"On the contrary, it is General Mao Gong."

Su Dingfang looked at Li Shiyun twice, and suddenly smiled:

"I have been in Chang'an for 30 years, and I am still as famous as you."

"Now add another thirty years to the ......"

The words are not finished, but the meaning is clear.

Li Shiyun snorted coldly, and he was bored.

Li Jing didn't participate in any of this, but sighed a little enviously:

"The Western Turks were able to participate in the conquest of such a great power......

……

"The Vast ...... of the World"

Liu Bei muttered, remembering the previous words of the light curtain:

"Small countries have no sovereignty, and weak countries have no diplomacy."

"This is especially true for those who have lost their country."

Then I was slightly fascinated:

"I don't know if I will be able to see this Ardashir in my lifetime."

The Tang emperors were facing the end of the Sasanian world, and they were facing the end of the Sabbath Empire.

But precisely because it is so far away, at this distance, whether it is conflict or cooperation seems unlikely, and the only thing that can be done is probably cultural exchange.

Therefore, Liu Bei was a little interested in the founder himself.

Zhang Fei was very interested:

"What if we send a letter to reveal that Ardashir is going to rebel?"

Kong Ming shook his head after pondering it carefully:

"In the meantime, the cost can be paid by Yide."

"What will happen, you will know when you do it."

Zhang Fei retreated at the time:

"Forget it, I don't have such an interest in spending money to listen to the sound."

Kong Mingden laughed.

Only Liu Ba in the hall still remembers the purpose at the beginning:

"This Tang Dynasty wants to quell the riots in the Western Regions, what does it have to do with the Sassanid Empire?"

Kong Ming was interested:

"It's just a plan to kill the enemy."

"Let's see."

[After going to Ninishi from Li Zhi, Pei Xingjian and his party went on the road.

From Chang'an to the Western Regions, the trek was very hard, so after arriving in Xizhou, Pei Xingjian couldn't wait to use his connections.

After 20 years of living in this place, it can be said that there is no one big or small who is unconvinced, and they can't wait to come over to wash the dust for Pei Xingjian.

At the banquet, the locals in the Western Regions also asked about Pei Xingjian's work:

Escort the new Persian governor to the Persian kingdom to take office.

And during the banquet, Pei Xingjian also complained loudly, saying that it was simply looking for death on the road in the hot summer, and he would wait for the weather to cool down in autumn before leaving.

The news was quickly sent to the Western Turk chieftains, who were plotting the rebellion, to the relief of the two:

I'll just say, how could the imperial court send a dozen people here to quell the rebellion?

Pei Xingjian had already planned about this, and first summoned the heads of the four towns of Anxi, saying that now the water and grass are abundant, and it is just right to hunt, so the heads of the four towns can gather some young children to go out and play together.

No one doubts this, after all, Pei Xingjian had this interest when he was the protector of Anxi.

Thanks to Pei Xingjian's own reputation, tens of thousands of people were quickly pulled up, and the success of Pei Xingjian's work in the Western Regions can be seen.

So more than 10,000 people turned left and west in the name of hunting, and soon inadvertently arrived at the camp of Ashina Duzhi, who was plotting to rebel.

Pei Xingjian was also very reasonable, he asked more than 10,000 people to wait in place, and then sent a messenger to reason.

Ashina Duzhi was very sensible, so he chose to surrender at that time, and then Pei Xingjian used the token of Ashina Duzhi to summon the chiefs of the Western Turkic tribes who conspired to rebel and arrest them together.

Then an elite cavalry was selected and directly raided the camp of another rebel leader, Li Shalu, and was arrested on the spot.

At this point, this turmoil that had not yet occurred disappeared invisibly, and the leaders of the Western Regions spontaneously praised Pei Xingjian in Broken Leaf City, and the two rebel leaders were also escorted to Chang'an to express their merits.

The most unlucky should be the Nirvana Master, Pei Xingjian returned to Chang'an with the team of Gonggong, and he didn't care about him at all.

The Nirvana who was thrown away when he ran out could only go to Tocharian by himself.

The last royal family of the Sassanid dynasty lived in Tocharian for twenty years, but in the end he failed to realize his dream of restoration.

In 707, Ninishi returned to Chang'an and accepted the position of general Zuo Weiwei granted by Tang Zhongzong.

In the end, he died of illness in Chang'an, which drew an end to the Sassanid Dynasty. 】
