Listening to Li Su's words, Li Shimin couldn't help but be silent.

This technology is indeed beyond Li Shimin's imagination.

But if you read the Four Books and the Five Classics, can you build a railroad and make a train?

Can you study winter wheat and develop crops that can be harvested twice a year?

So, what do railways, trains, winter wheat and double-cropping rice mean for Datang?

What exactly does he want these scholars who study the books of the sages and sages? Or do you want these scientific and technological talents?

Or, both!

According to the thinking of ordinary people, it is natural that both talents are wanted.

However, Li Shimin knew very well in his heart that it would be difficult to pass this decree.

The reason is that all the civil officials in the DPRK and the Central Committee are studying the Four Books and the Five Classics diligently, and they are made to admit that physics and chemistry are crooked and heretical in their eyes, and they are extremely difficult.

Therefore, after pondering for a long time, Li Shimin couldn't help but say: "Su'er, this matter needs to be considered in the long run. However, you can now Yizhou and open up a pilot out. ”

Listening to Li Shimin's words, Li couldn't help grinning and happily agreed.

Li Su understands that in fact, his father has already been tempted, but he has too many things to think about, and he has not yet made a final decision.

……

Yizhou is almost over, and the king of Shu, Li Su, has been in Yizhou for less than a year, and the entire Yizhou has undergone earth-shaking changes.

The answer handed over by Li Su has exceeded Li Shimin's expectations for him.

After the inspection, Li Shimin seemed to be able to leave.

After all, it was impossible for him to leave Chang'an for a long time.

Before leaving, Li Shimin summoned the king of Shu and a cadre of generals and held a secret meeting.

The reason why Li Shimin agreed to come with these generals was actually for other purposes.

And the content of this meeting was how to take Tuyuhun and Tubo in one fell swoop, and even Nanzhao was also in their consideration.

In the original historical trajectory, why didn't the Tang Dynasty want to take Tuyuhun and Tubo?

It is because of the harsh environment in Tibet, the output is very small, and the road is difficult and dangerous.

The effort and the return are not proportional at all, and it is difficult to educate.

Therefore, the Li Dynasty, even if they had the strength to defeat them, generally did not attack them.

But now it's different, now there are trains and railways, there are concrete roads.

It can be said that the problem of the road is solved.

Datang can quickly dispatch troops, and once there is any situation, it can be controlled at any time.

And Li Shimin is eloquent and strategic, and he wants to be the first emperor of the ages.

And to be an emperor through the ages, the most important point is to expand the territory.

Then, the current Tubo and Tuyuhun have entered Li Shimin's sight.

After summoning a group of veterans, Li Shimin couldn't help but say in a deep voice: "Tubo and Tugu have not been educated for a long time, and this year they even dared to invade our Tang territory. Now there are three new crops in Yizhou, and when the harvest is harvested next autumn, the grain is bound to be bumper harvest. ”

And now Datang has opened up a train track from Chang'an to Yizhou, which can quickly transport soldiers and grain and grass. Therefore, I am ready to wait for next autumn harvest to gather troops immediately, and quickly take Tubo and Tuyuhun with lightning speed. You can talk about it. ”

The big trouble of the Tang Dynasty is not Tibet, but the Turks.

But Tubo is in the southwest of the Tang Dynasty, and it always makes trouble at critical moments.

And the most important point is that now there is only one railway from Chang'an to Yizhou in Datang.

Only by relying on the railway can they quickly transport soldiers and food, so they now have to attack Tubo and Tuyuhun first.

After taking Tubo and Tuyuhun, the southwestern border of the Tang Dynasty could be stabilized and become the granary of their rear.

And after Li Shimin finished speaking, the eyes of these veterans couldn't help but light up.

They hadn't fought a war for too long since they had used troops against the Turks.

They are all about to be idle, so when they hear that there is going to be a war, their eyes are shining.

Cheng Yanjin was the first to shout: "Fight!" You have to fight, hit hard! I am the first to agree, count me as Lao Cheng! ”

Qin Qiong also said: "Your Majesty, you must fight, open up territory and expand territory for my Tang Dynasty!" ”

Wei Chigong and a group of other old ministers agreed with Li Shimin's opinion.

Huo, now there is not a single civil servant here, they are all a bunch of military generals, all militants.

Hearing that everyone agreed, Li Shimin was also extremely satisfied, and couldn't help but say: "Okay, since you all agree, then ......"

At this moment, Li Su got up helplessly and said, "Father, slow down." ”

Li Shimin frowned and said, "Su'er, do you have different opinions?" ”

Li Su couldn't help but say: "Father, the son thinks that Tubo and Tuyuhun have complex terrain and a large population. Attacking them is really a matter of labor and money. Erchen thinks that there may be a better way. ”

After listening to Li Su's words, Li Shimin couldn't help frowning and asked, "Su'er, then tell me, what better way do you have?" ”

Li Su couldn't help but say: "Father, the emperor, the sons and daughters think that we can engage in economic aggression. ”

"Economic aggression?" Li Shimin was at a loss: "What is economic aggression?" ”

Li Su smiled and said: "Father, economic aggression is that our Datang sells our luxury goods to Tubo and Tuyuhun in exchange for their mutton and fur. Then, they were taught how to build concrete roads, and they were allowed to build roads in Tibet. ”

Hearing the first half of Li Su's words, those generals were still smiling, but after hearing it, their faces changed color, and they couldn't help but say: "Don't do it at this time!" ”

"This is a capital enemy!"

"This is absolutely not possible!"

And Li Su smiled slightly: "Why not?" The reason why Tibet is difficult to attack is because their terrain is complex, and the roads are narrow and not easy to pass. But what if they build roads in the country? ”

"When the time comes, if we want to attack them, we can drive along the road they have built! And if we attack Tibet now, not only will we suffer heavy losses, but we will still have to build these roads ourselves! ”

After listening to Li Su's method, these generals couldn't help but look at each other, and for a while, they were speechless.

Li Shimin's face also showed a look of deep thought.

After a while, Cheng Yanjin couldn't help but say: "Your Highness, you are still bad!" ”

Qin Qiong said with a smile: "That's right, it's a bad stomach!" ”

"Bad is bad, but I like it!"

Li Su, who listened to it, was full of black lines, Huo, is that how you praise people?

And this matter was finally settled.
