Su Changqing naturally wouldn't agree with Li forgetting worry and running to Songzhou.

That kind of war scene, for her, of course, the farther away the better.

She respects those soldiers who protect the country, and knows better that when times are quiet, there are people who are carrying weight.

However, understanding does not mean that she is willing to take risks on the battlefield with her own men.

This is also human nature.

What's more, it had nothing to do with them, and she wouldn't agree. Li forget worry ran to the battlefield where arrows flew indiscriminately just because of curiosity.

Li Qieyou also knew her mind. He smiled silently and said nothing more. The party continued on the road and rode slowly towards Yizhou.

Li forgot to worry about riding on his horse, but he was thinking about Songzhou.

He didn't think about sneaking to Songzhou. After all, Tuyuhun only wanted to make a small fuss even if he made a mistake.

Even history books are too lazy to record, so it's not a big deal.

When he goes to Songzhou five hundred miles away, maybe Tuyuhun will retreat.

Moreover, with Su Changqing, he could not be so irresponsible. He left his three women and sneaked to Songzhou to satisfy his curiosity.

The idea he had just had was just a whim.

Being stared at by the beautiful boss, the "henpecked" symptom of this goods broke out. The idea of going to Songzhou to watch the ancient battlefield has long been forgotten.

Li forgets worry only because of Songzhou. He thinks of the twelve year battle of Songzhou in Zhenguan and the powerful enemy of the Tang Dynasty, Tubo.

In later textbooks, Princess Wencheng's marriage to Songzan Ganbu was praised as a symbol of Tang fan friendship.

In fact, Li forgets to worry but knows that this is bullshit.

Not to mention how fragile, unreliable and even humiliating the "friendship" maintained by women and relatives.

In Li's opinion, the marriage is a stain on Li Er's life.

It's not as bloody as the ancestors of the Ming Dynasty who "don't make peace, don't compensate, don't cut land, don't pay tribute, the son of heaven keeps the gate of the country, and the king dies the country".

Princess Wencheng married to Tubo and brought vegetables, grain seeds, exquisite handicrafts and the advanced production technology of the Tang Dynasty. However, the Tubo people did not think it was friendship at all, but regarded it as the awe of the Tang people to Tubo.

As for Princess Wencheng, she is not loved by Songzan Ganbu.

When Songzan Ganbu married Princess Wencheng, he already had a Nepalese Princess Chizun as his wife and was quite favored.

The so-called red palace built to marry Princess Wencheng, that is, the Potala Palace of later generations, was built for Princess Chizun.

It's also quite easy to distinguish the true from the false. If the palace is built to alleviate Princess Wencheng's homesickness, its architectural style will not be nibra style palace, but Datang style palace.

Li forgets to worry about what the Potala Palace looks like in future generations.

Saying that the Potala Palace was built by Songzan Ganbu to marry Princess Wencheng is pure lying with open eyes.

It is recorded in the records of the king of Tibet that Princess Wencheng has been in Tibet for many years. She has no children and no pet. She has a mediocre status and serves Songzan Ganbu's daily life like a servant girl.

Nine years later, Songzan Ganbu died and Princess Wencheng was widowed for 31 years... This is the real experience of Princess Wencheng.

Li Qieyou secretly made up his mind that in any case, he could not let this happen under his own eyes.

If the Tubo Prime Minister Lu dongzangan went to the Tang Dynasty to ask for a marriage, Li Lianyou even began to wonder whether to kill the goods directly.

Kill Tubo!

The idea, like a wildfire, suddenly burned in Li's heart and lasted for a long time.

He even had an impulse to turn around and go back to Chang'an city to find Li Er, Fang Xuanling, Du Ruhui, Cheng Yaojin and others to plan the matter.

Li Qieyou felt that ten years of preparation should be enough for Datang to accumulate strength, destroy Tubo in one fell swoop and bring it into the territory of Datang.

After crossing the Tang Dynasty, Li forgets worry and has a clear goal for the first time.

The Tang Dynasty and Tubo fought against each other for a hundred years, and the battles recorded in historical books occurred more than 190 times.

However, as strong as the Tang Dynasty, it has always been unable to do anything about Tubo, let alone bring Tubo into its territory.

In addition to the strong Tibetan army, the main reason is geographical problems.

As we all know, due to the plateau reaction on the Qinghai Tibet Plateau, even in the era of cold weapons, even the Tang cavalry still had nothing to do with the plateau reaction when they got to the plateau.

In particular, the Tang Dynasty did not understand the cause of altitude sickness. It only knew that it was a disease called "miasma" or "miasma", and there was a lack of effective prevention and treatment.

In addition, in Datang, cotton was not planted and used on a large scale.

The soldiers lacked good means to keep out the cold, and the low air temperature and difficult logistics supply in the plateau restricted the iron cavalry of the Tang army from attacking Tubo.

Li forgets to worry that altitude sickness is not difficult to overcome. When entering the plateau above 3000 meters above sea level, 50% to 75% of people will have altitude sickness, but after three to ten days of adaptation, the symptoms of altitude sickness will gradually disappear.

In addition, Rhodiola, a traditional Chinese medicine, can effectively overcome altitude reaction, so overcoming altitude reaction should not be a big problem.

The difficulty of attacking Tubo lies in keeping out the cold and logistical supplies.

To keep out the cold, he needs to plant cotton on a large scale. Li forgets his worries and plans to discuss the matter with Li Er after returning to Chang'an.

Logistics is not difficult.

Li Qieyou immediately thought of lunch meat, meat floss and fried noodles, which can be easily made in Datang for the army to eat.

In this way, the Tang army could go into battle with light equipment.

Now, after he and Yan Liben made the water hammer, the Tang army was even better equipped. In this way, Li forget worry did not believe that Tubo could not be destroyed.

Li forgets to worry and thinks that if he wants to destroy the strong enemy of Tubo within ten years, he must start planning and preparation in advance. That is, he must send all kinds of spies to go deep into the plateau to find out the climate, roads and geographical environment in Tubo, so that the army can be targeted.

Otherwise, if hundreds of thousands of troops set out to fight, even if they hit the plateau, their eyes will be black.

Thinking of this, Li forgetful suddenly slapped himself on the head.

Thanks to his boasting of being a military fan, he even forgot such an important thing.

In order to build his mansion and castle, he made a sand table, which was treasured by Li Er and Cheng Yaojin.

But he forgot to get out the map and give it to Li Er.

It goes without saying how rough and crude the map of Datang is today. It is also unreliable for Li forgetful to imagine drawing a map out of thin air.

But how did he forget that Su Changqing's mobile phone had navigation software.

Even if there is no network or GPS, there are downloaded offline maps!

Those city maps of later generations are naturally useless, but even if they are simple national maps, copying and drawing them down, the accuracy of their proportion is also the existence of all maps of the Tang Dynasty!

Where does he need to do so many messy things in Chang'an City?

If you present this map, you can immediately blind Li Er and the 24 K krypton gold dog eyes of all the state leaders!

Is it still a matter to change Su Changqing's title?
