Since hearing about Lu Heng's matter yesterday, Li Shimin's mind has become more and more active.

At first, he wanted to get this kid to the barracks, firstly, to make it easier for him to avoid the sight of the five surnames and seven hopes, so as not to cause any trouble in Chang'an.

Second, it was because he hoped that Lu Heng could get out the previous heavenly thunder.

This thing works wonders when it's put in a war!

When he settled accounts with Lu Hengqiu earlier, Li Shimin had already thought about this matter.

I was going to get it later...... It's just that when he heard that Lu Heng was as powerful as an ox yesterday, he really felt that this kid could have a great career in the barracks!

After hearing Lu Heng's refusal, His Majesty Li Er immediately pulled his face down.

"Why wouldn't you?"

Lu Heng felt that Li Er's anger came inexplicably.

He said confidently:

"Your Majesty, if you want to make this explosive in large quantities, you will definitely need a lot of raw materials."

"Carbon, sulfur and saltpeter, and sugar, are you ready?"

"And there hasn't been any war recently, so don't worry!"

Although quite justifiably.

But when he heard that Li Shimin was going to make explosives, a sense of foreboding rose in his heart.

Sure enough.

His Majesty Li Er, who was in front of him, turned pale and said:

"Not in a hurry?"

"Do you know that in the past two days, the envoy of Tubo has come to Chang'an?"

"The messenger will propose marriage on their behalf of Zampu and Songtsen Gampo!"

"I didn't want to agree, so I refused, and as a result, the messenger looked extremely unhappy, and even confronted me in the face."

"Hehe, Lu Heng, guess what, after he goes back and reports the matter to Songtsan Gampo, what will Tubo do?"

Lu Heng's heart was full of grass.

Made, why did you forget about Princess Wencheng and her relatives!

Although I can't remember the specific time, there must be a big problem behind this harmony, otherwise Li Shimin would not have agreed to the harmony.

Even if Princess Wencheng is just a clan daughter and not his biological daughter, His Majesty Li Er will not do such a thing as a kiss unless it is absolutely necessary.

Half a day.

Lu Heng hesitated:

"Tibet...... Very strong? ”

"Do you have to use explosives to repel them?"

Li Shimin sighed.

He explains:

"Although the Tang Dynasty did not have a large-scale war with Tibet, and they also sent envoys to reconcile with the Tang Dynasty in the eighth year of Zhenguan, I always felt that there was something wrong with this Tibet."

"I knew about Songtsen Gampo two years ago."

"In the third year of Zhenguan, he put down a rebellion with the help of his ministers, and then ascended the throne at the age of twelve."

"After ascending the throne, listening to the news from Biansai, Tubo has also developed very well under his governance, and even stronger than before."

"Now he is not even twenty years old, but he has become a monarch who is trusted by the Tubo people, isn't this ability?"

"...... with a guy like this"

"I think there will be a big war to fight in the future."

After listening to this, Lu Heng's whole person was not good.

Boy.

It turns out that this is the background story of Princess Wencheng and her relatives?

Even if you don't know this history, anyone who has read the book knows how high the prestige of Songtsen Gampo is in Tibet.

In later generations, the people of that place still held this wise king in high esteem.

The king is wise, proving that the combat effectiveness of the opponent's army is definitely not too weak.

Unless you make direct peace now, the battle between Datang and Tubo is already on the verge of breaking out.

Lu Heng's mind was spinning rapidly.

Princess Wencheng made peace with Songtsen Gampo, was it to stop this war, or did it only decide after the war?

While I was thinking.

Li Shimin spoke, and his voice became deeper and deeper.

"What, do you have something unspeakable?"

"Is there any difficulty in making this explosive, or are you not willing to make such a weapon for Datang?"

"Or ......"

"Do you think I should marry a princess to that bitter cold land?"

Lu Heng came back to his senses and hurriedly waved his hand.

He explains:

"Erchen has just married Princess Yuzhang, so naturally she won't let any of her sisters marry far away from Tubo, if she knows about it, she won't cry to death!"

"It's just, doesn't this battle have to be fought?"

"They are dissatisfied with Datang, so let's take out explosives to deter them."

"After seeing the strength of Datang, I don't dare to act rashly when I want to come to Tibet."

His Majesty Li Er frowned:

"How do you want to deter?"

"Tibet is a land outside the country, and I have heard that most of them are still slaves, and only a few are slave owners."

"If there is really a war, Tubo will not care about the lives of slaves at all, and treat human lives as a mustard."

"Against such an enemy, ordinary deterrence simply does not work."

"If you think that a little scare will make them retreat, that would be naïve!"

That's the same thing......

Lu Heng also knew before that even in modern times, the slavery system in Tibet was not completely abolished until a long time after the founding of the country.

Slavery has been practiced for thousands of years, and it is not so easy to abolish it, and they do not feel distressed at all when they start a war.

This is completely opposite to the national conditions of Datang!

Now that the troubled times have just ended, the Tang Dynasty has just been established, and what is most lacking is the population, that is, the labor force.

If it weren't for the provocation of others going too far, His Majesty Li Er would not want to waste his troops in vain.

After a moment of contemplation.

Lu Heng slowly opened his mouth and asked:

"Has the envoy of Tibet left Chang'an?"

Li Shimin shook his head:

"I haven't left yet."

"They insisted on waiting for ten days, saying that if I didn't change my mind after ten days, I would leave Chang'an and return to Tibet."

Lu Heng grinned and laughed.

"It's good that you're not leaving."

"After two days, how about you organize a military exercise?"

Li Shimin was stunned.

He frowned and said:

"What is a military exercise?"

"Could it be that it is the scene of a rehearsal of a large army? That is inevitably too provocative, and I am afraid that they will add even more fuel and vinegar when they go back! ”

Lu Heng thought about how to explain.

Half a day.

He scratched his head:

"Not like that."

"It's equivalent to you directly bringing Tibetan envoys to the camp in the western suburbs, so that they can see how our forbidden army is usually trained."

"You can also divide the people in the entire barracks into two sides and attack each other - of course, the bloodless kind, practice the style."

"At that time, the sons will get the explosives out again, so that they can see the power of this thing with their own eyes."

"After seeing it, if they still want to start a war with Datang, then they have to weigh it carefully!"

Li Shimin pondered for a while and felt that this matter was really a bit of a trouble.

But then, a question came to him.

"The main deterrent of this fresh weapon was when it first appeared."

"If you let them know in advance that we have such a weapon...... If they really want to fight, won't they be prepared in advance? ”

Lu Heng smiled even more happily.

"That's what I want."

"With all the preparations, they can't control the horses from being frightened!"
