Soon after.

In the palace.

Li Shimin directly brought the three of them to the Liangyi Hall to facilitate conversation.

He doesn't have many rules, and he gets straight to the point:

"Now that you've thought of countermeasures, let's discuss what kind of charter we should have."

"Lu Heng, I was clearly asking how you want to deter Tibet, why did you get involved in sending people behind enemy lines?"

This is the fundamental reason why His Majesty Li Er brought a few of them back to the palace.

Preparing to send people to follow the Tibetan mission and sneak into the sphere of influence of Tibet, can this be in a place like a military camp? Only when he goes back to the palace can he rest assured!

Lu Heng smiled, his face full of righteousness.

"Father, the meaning of the son is very simple!"

"We're just getting ready."

"First of all, use a military parade to deter the Tibetan mission, let them feel how powerful the Tang army is, and overwhelm them from the momentum."

"Then, let people follow them and touch Tibet, it is not necessary to get their capital, it doesn't matter if they go anywhere else, just let them know that there is such a team at their doorstep."

"The purpose of this team's existence is not really to go head-to-head with them."

"Father, have you ever heard of a saying—"

"The enemy advances and I retreat, the enemy is stationed and I disturb, the enemy is tired and I fight, and the enemy retreats and I chase!"

The other three people present were stunned.

These simple twelve words may be nothing to others, but Li Shimin and Su Dingfang are both people who have fought for half their lives, how can they not hear the meaning?

Ponder for a moment.

After a long time, His Majesty Li Er let out a long breath and said:

"What a tactic!"

"Lu Heng, I never thought that you would have such a tactical talent!"

Lu Heng hurriedly waved his hand:

"No, no, I got it in my dream, and my son just said that he could do it, and he really wanted to go into battle in person, I'm afraid he couldn't adapt to it."

"It's primarily a strategic direction."

"Let's fight a guerrilla war with Tibet!"

Li Shimin nodded and shook his head again.

He can see that Lu Heng has no intention of being humble this time, and he is really talking on paper.

"Your idea is very good, I think those twelve words are no problem in many places."

"But have you ever thought about ......?"

"To deal with Tibet, the Tang Dynasty may not be able to use this guerrilla warfare?"

His Majesty Li Er popularized science:

"Maybe you don't know that there are several important towns at the junction of Datang and Tubo, one is Liangzhou and Shanzhou, and the other is Songzhou in Jiannan Province."

"The sergeants stationed there once told the court that sometimes there were conflicts with the Tubo people, and they wanted to chase after them, but they suddenly started to breathe halfway through, and even died a lot, but the Tubo people had nothing to do."

"It's called an air barrier."

"Tuyuhun came to attack the border, and Datang not only accepted the move, but even chased them to their hometown, and beat Tuyuhun into our vassal country."

"Tubo, it's really troublesome."

Hearing that His Majesty Li Er was actually giving himself a science about altitude sickness, Lu Heng was speechless.

As a modern person, after being bombarded with information, don't you know more about Gao Anti than this group of ancient people?

He pursed his lips and said:

"The one you mentioned is called altitude sickness, but anyone who doesn't live in Tibet will have it in the past."

"It's actually very simple to deal with high reactions!"

"As long as you don't die, as soon as you go up, you start exercising vigorously, and if you adapt more, you'll be fine."

Li Shimin was stunned.

What's the situation?

Baiqi Si once investigated Lu Heng, this kid has never left the vicinity of Chang'an since he was born, and a person who has never been out of a distant door can actually know the situation in a place like Tubo? !

He hurriedly asked:

"How did you find out?"

"Also, if it were really that simple, it would be able to deal with that qi barrier...... No, high anti, then why hasn't anyone found out for so many years? ”

Lu Heng's hands:

"Because in the past, they were all soldiers, and they either rode horses or marched quickly, and in short, they exercised a lot."

"Except for some chosen ones, the probability of high anti-reaction is very high."

"In general, there are only a few precautions."

"First, start making tea with rhodiola seven days in advance, this medicinal herb has already appeared, you let those soldiers next to Tubo look for it, you will definitely find it, it is very common."

"Second, don't take a bath after entering Tibet, everything is mainly to keep warm, and don't have any possibility of contracting wind and cold, people who have just gone will be easily unable to save once they get sick."

"Finally, when I got to a place where I couldn't breathe, I camped straight away, stayed in place for a while, and then went up after getting used to it."

In fact, the easiest way is to inhale oxygen and put on an oxygen cylinder, but Lu Heng didn't mean to mention this at all.

Potassium chlorate and manganese dioxide are basically impossible to get out in today's Datang.

As for the rest......

If he can use electrolysis, or large-scale industrial oxygen production, what is he doing in Tibet? Isn't it fragrant to power up the whole Datang?

Without this preparation condition, it is useless to mention it.

Take 10,000 steps back and say, even if it is made, the oxygen cylinder and oxygen bag have no production conditions and cannot be taken away.

Thinking of this, Lu Heng was inevitably a little melancholy.

Although he is a science and engineering dog, it stands to reason that he should be able to create a good infrastructure for Datang.

But now the basic conditions are too poor!

There is still a long, long way to go if you want to achieve industrialization!

Lu Heng was melancholy here.

The few people next to him were already numb to listening.

They couldn't imagine how Lu Heng knew about these things on the plateau and how he got a solution.

Su Dingfang muttered to himself:

"That's amazing...... Is this the legendary land god doctor......"

"It's ridiculously strong."

Zheng Yang was a little dazed, but he had a strong trust in Lu Heng:

"What Doctor Lu said must have a point!"

Li Shimin: ......

Li Shimin pinched his temples and said in a deep voice:

"In that case, then I will follow what you say, let the soldiers in Songzhou and Shanzhou try this method first."

"If it works, I'll agree with the tactic you mentioned!"

Although many Tibetans were also herders, they preferred to settle in one place more than the Turkic nomads.

This half-agrarian, half-pastoral race was not as difficult to fight as the Turks, and at least they had a place to settle down and gathered, rather than a steppe full of homes.

Just overcome that terrifying and pervasive qi barrier.

Fighting them as a guerrilla tactic......

Perhaps, it really works!

Lu Heng gritted his teeth and said:

"Okay, you send someone to deliver the letter and let them try!"
