There is a saying that the heart is more than enough but the strength is insufficient.

Niu Jinda and his soldiers are in such a state, and they think very well in their hearts, they can catch Tubo Zampu and become famous in the government and the opposition, but their tired and tired physical condition can no longer support them to achieve their goals.

When I was in Kang Yanchuan, there were only a few dozen people who were unwell, and after leaving Kang Yanchuan for a day, the number of people who were unwell had increased to hundreds, and the situation was even worse the next day.

The non-combat attrition, which came faster than the plague infection, made Niu Jinda no longer have the heart to chase down, and the soldiers didn't want to chase anymore.

So on the third day, Niu Jinda began to return, and more and more people had altitude sickness on the way back, and the most serious ones were already dying.

Say it's because you suddenly went up from a low altitude to a place of more than 3,000 meters, so you have altitude sickness?

Not really, because they don't suddenly come to a high altitude, but gradually increase in altitude.

Starting from Longyou, the altitude is about 1,000 meters, and the average altitude to Longnan is a little higher, all the way from a few hundred meters to more than 1,000 meters and then to more than 2,000 meters above sea level in Songzhou, which took nearly 20 days, to say that the adaptation is almost adapted, and from Songzhou to Seda, to Jiangda, although the altitude is from more than 2,000 meters to more than 3,000 meters, the time is also shorter, but there are about ten days, and there is no problem with adaptation.

Like the kind of travelers who rode into Tibet in later generations, there were very few altitude sickness that happened to them, and there were not many girls, because they had a long adaptation process in the middle of the altitude increase.

In addition to those who are particularly susceptible to hypoxia, the step ascent is the safest and safest way to prevent acute altitude sickness. Pen & Fun & Pavilion www.biquge.info

Therefore, the main reason for the altitude sickness of so many soldiers is definitely not because they suddenly came to a high-altitude area, if Wu Yuanqing was there, he would definitely say to Niu Jinda: "Old Niu, you and your brothers are too tired these days, you can't eat or sleep well, you spend almost every day on horseback, your body is tired, it's no wonder that you don't have problems and are not affected by the plateau."

Yes, the body is too tired, too tired, this is the most important reason why the soldiers suddenly have a large-scale altitude sickness after almost 20 days on the plateau.

There are many factors that can induce altitude sickness, such as excessive climbing, excessive physical activity, cold or climate changes, hunger, fatigue, insomnia, motion sickness, emotional stress, upper respiratory tract infection, and other factors.

It is definitely impossible to eliminate motion sickness, and it can also be eliminated if you are too anxious on the high speed, and almost all other items can correspond to Niu Jinda and his soldiers.

Physical activity is large, not to mention more than ten days of controlling horses, wielding knives to fight physical activity is not strange, every day to eat on time, when there is no war situation, hurry up to eat two bites, rations are not much to eat, physical consumption is so big, of course you will be hungry, no running, cold also, although this time is not yet winter, but the plateau day and night temperature difference is large, the night is very cold, they are not like Wu Yuanqing still carry so many thick clothes, even with thick clothes can not be worn, the pursuit of the night sleep armor is not solved.

Insomnia and emotional stress are all indispensable during the war.

With so many factors that induce altitude sickness gathered together, it is time for the iron man to fall, let alone a mortal person in the flesh.

Speaking of which, Niu Jinda and they should be very happy, the chased Songtsen Gampo doesn't know about this situation, otherwise if they run slower and catch them for a few more days, the Tang army will collapse without a fight.

Niu Jinda returned to Kangyanchuan to rest for two days, Cheng Yanjin arrived, after learning the situation, Cheng Yanjin sighed, regretting that his old friend could not catch Tubo Zanpu.

However, the successful escape of Tubo Zampu is a foregone conclusion, and there is no need to dwell on it anymore.

It stands to reason that at this time, the emperor's desired goal has been achieved, defeated the Tubo army, and hit the Tubo country, it is time to pass the good news back, and then wait for the reward class to return to the court, but Cheng Yanjin is unwilling to go back like this, and competes for the opportunity to lead the troops, but he has not achieved an inch, and it is too faceless to go back.

Wu Yuanqing, who then rushed to Kang Yanchuan, also pouted on the side, saying that it was not good to fight a good battle, others thought that Uncle Cheng was here to take credit, and he would definitely be ridiculed by other generals when he went back, especially by Uncle Wei Chi.

Cheng Yanjin can't stand others using Wei Chigong to provoke him, he and Wei Chigong are living treasures and enemies in the court, neither of them wants the other party to be in the limelight, and they will tread each other sarcastically and step on each other at every opportunity.

In order not to go back and be ridiculed by Yu Chi Lao Hei, Cheng gritted his teeth and decided to continue fighting, grandma's, although he didn't want to kill the lord of Tubo in one fell swoop, but he could rage in Tubo and make some contributions, anyway, he couldn't let Yu Chi Lao Hei's old goods be flattened.

And the vagueness under the emperor's order said that it was to teach Tubo a hard lesson, but he didn't say anything about the degree of ruthlessness, so it was not wrong to continue to fight.

The emperor can blame the light shot, but he definitely can't blame the heavy hit, right, so, just let go of Kaka and do it.

So Cheng Biting Jin rate and Zhi Zhi Sili led 15,000 men and horses to start a wreaking havoc in the territory of Tubo, their men were not equipped with bombs, naturally the fight will not be as smooth as Niu Jinda's 10,000 people, but the remnants of Tubo who have long been scared by Niu Jinda do not have too strong resistance.

In a few days, more than a dozen cities around Kangyanchuan were conquered by Cheng Yanjin, and the defenders inside and the remnants of nearly 10,000 defeated soldiers were also wiped out.

After that, two other troops and horses led by Hou Junji and Liu Lan totaling 25,000 troops and horses also cleared from this offensive route opened by Niu Jinda.

The remnants of the Tibetan forces along the road from Songzhou to Kangyanchuan have all been wiped out, but this is not over, and they will continue to fight south and west.

Because as the commander-in-chief of the operation, Hou Junji called several managers together for a military meeting, although Wu Yuanqing was too lazy to participate, but afterwards I heard that General Hou did not want to be said that this expedition was a lie to win, so he must personally attack the city and make meritorious contributions before he was willing to give up.

In this regard, Wu Yuanqing is 100% supportive, he knows that it is unrealistic to rely on 50,000 people to wipe out Tubo, but how much territory can be occupied, no one has too much territory.

In order not to drag the army back, Wu Yuanqing took over all the logistics and supplies of several people and horses.

In addition to sending some people from Songzhou to help, Wu Yuanqing also selected many local famous people in the occupied cities such as Seda, Jiangda, and Kangyanchuan to help manage and raise grain and grass.
