Not surprisingly, on the day after the parade, Lu Dongzan asked His Majesty Li Er to return on behalf of the mission.

His Majesty Li Er was very generous, and with a wave of his hand, he directly issued them the customs clearance documents of the Tang Dynasty, and even covered his own jade seal, so as not to be targeted when they passed by Tuyuhun.

Lu Dongzan was very moved, and thanked him again and again, but His Majesty Li Er only said that Datang and Tubo were friends, and they should be.

When the Tibetan delegation returned to the inn to pack their luggage.

Lu Heng walked around from behind.

"Father, the sons will go to the post station to inform Wang Xuance of them."

He arched his hand and said:

"Since the Tubo people want to go back through Tuyuhun, then this matter is better than going from Songzhou."

"At that time, no matter how big a mess there is, any pot can be thrown to Tuyuhun."

"It's okay to kill only two messengers!"

Li Shimin was stunned for a moment.

I don't usually see it......

Is this kid so murderous???

He frowned and said:

"The main purpose of arranging this group of so-called horse bandits to go out is to be scouts, sneak into the Tibetan Plateau, and find out where their forces and tribes are."

"What is the use of killing a few messengers like you?"

"No way!"

Lu Heng also knew what Li Shimin was worried about.

Aren't you just afraid of startling the snake?

He waved his hand:

"No, no, father, our fundamental purpose is to deter Tibet and make them dare not move."

"Everything else is just a pre-plan, isn't it?"

Li Shimin nodded with some confusion.

Lu Heng continued:

"The killer that Erchen said is not a simple killing."

"Instead, let the horse bandits use gunpowder and slaughter them in a crushing manner!"

"During the military parade, the Tibetans only briefly saw the sound and power of gunpowder, but they didn't actually have a clear understanding of it."

"But if you kill people with gunpowder, they will clearly know that Datang is not something they can afford to provoke."

"Whether it's for the sake of recuperation and don't fight, or for the stability of the border stoppers, at present, before we don't have a large number of soldiers who can adapt to the plateau, it's better not to fight."

"The main thing is ......"

"Don't let them continue to want to kiss!"

"Even if she is just a woman from the clan, her knowledge is far stronger than that of the Tibetan king. Once a capable person is sent over, I am afraid that Songtsen Gampo will take the opportunity to steal the various techniques of the Tang Dynasty to strengthen himself. ”

"This is raising tigers for trouble!"

Li Shimin fell silent.

He knew that Lu Heng was not wrong.

From ancient times to the present, the main purpose of harmony is to calm the flames of war and become in-laws.

It's not just that you can't beat it to get along.

The big man is so strong, didn't he still send Zhaojun out of the plug?

And now, the Tubo people are not as foolish as the Huns at that time, and it is impossible to take a palace maid to pretend to be a clan maid and a relative, which will only intensify the contradictions between the two sides, and even give Songtsen Gampo a very legitimate reason to send troops.

Didn't you Datang look down on me? Lao Tzu hits directly!

But if you really send a cultured and literate clan girl to the past......

The water spilled by the married daughter.

In a few decades, when the technology of the Central Plains is completely mastered by Tubo, the Tang Dynasty will face a greater crisis at that time.

Face more powerful enemies!

Long.

His Majesty Li Er finally nodded.

"Okay, I'll do it."

"I'll leave it to you to deal with this matter."

He reached out and took a blank document that had been prepared, on which he wrote in detail the composition of the "horse bandits" team, and then arranged for all of them to be good citizens.

After writing, he handed the document to Lu Heng:

"Since the Tubo mission wants to borrow Tuyuhun, it should be useful for them to go ahead with this document."

I have to say that Li Shimin's consideration is very thoughtful.

A team of horse bandits with the identity of a good citizen of the Tang Dynasty, even if they fail to wipe out the Tubo mission at that time, and are chased and killed by the defenders on the Tubo border in the future, they can escape to Tuyuhun in time to be blessed with this document.

What's more, you can run directly from Tuyuhun back to Shanzhou in the Tang Dynasty!

Whether it is to fight guerrilla warfare according to the original plan or to run away, this document is a very useful way out.

Lu Heng was overjoyed and arched his hand:

"The father is thoughtful, and the son is ashamed!"

"Robbery, you're really experienced!"

Li Shimin's face darkened.

He took back the paperwork he was handing over in his hand and smashed it directly into Lu Heng's arms!

"Shut up if you can't speak!"

"Do you want to hear what you're saying?"

"The war between the two countries, how can it be called robbery, this is a fucking tactic!"

………………

Outside the city of Chang'an.

Post.

There are subtle differences between this place and the inn.

The post stations of the Tang Dynasty are generally prepared for the army and messengers, and the messengers in the military camp have the highest priority.

It is inevitable that there will be an urgent military report of 800 miles to be delivered, and the post station will always prepare good horses for the soldiers returning from the front line to deliver the letter.

However, in the past two days, the post station has been temporarily closed.

There hasn't been any fighting on the front lines lately, and besides, the people who live here now are sensitive and don't want anyone else to know.

Lu Heng came with a hundred horsemen on horseback.

After dismounting, he turned to He Dedao, who was accompanying him:

"You can take them and wait outside, and I'll go in and explain something."

He De replied.

He led the Hundred Cavalry Division to protect Lu Heng, but he was really a bit of a snake shadow by the previous assassination, and he couldn't do it if he didn't protect it.

After Lu Heng showed his token, the people at the post station directly let him go.

After going in.

Wang Xuance and Zheng Yang, who were waiting in the hall, saw him and immediately got up.

Wang Xuance arched his hand and said:

"Pony, is there any news?"

Lu Heng nodded:

"Yes, the Tibetan mission has asked His Majesty for customs clearance documents, and we will leave for Tibet tomorrow."

"I'm here because their route has changed."

"Contrary to expectations, when the mission returned, it would not follow the original route from Jiannan Road through Songzhou to enter the Tibetan border, but would instead go west from Chang'an and go back directly through Tuyuhun. This road is much easier to walk and faster than Jiannan Road. ”

"Prepare yourself, plan your route, and set off tonight."

Hearing this, both of them were stunned.

Go to Tuyuhun???

Zheng Yang hesitated:

"But we went out as horse bandits, not officials, nor messengers......"

"If you go to Tuyuhun one step ahead, will you be discovered by their army?"

Lu Heng smiled.

He took out the document written by Li Shimin himself from his arms and handed it to the two of them.

"Your Majesty has already thought about it for you, so you don't have to worry about this."

"You take the paperwork and ambush it in the place between Shanzhou and Tuyuhun."

"When the Tubo mission enters Tuyuhun and relaxes its vigilance, you can just do it directly!"
