As a well-known think tank in Tibet, Lu Dongzan naturally will not sit still, early in the morning with henchmen and a large number of treasures do not know what to do, dispatched the Praetorian Guard and Yongzhou's infantry yamen, and only caught some small fish and shrimp that have little value, Li Er had no choice but to order a nationwide search, issued a general order, and offered heavy rewards, and officials everywhere must be on standby, especially a pass, must be inspected in detail, and Lu Dongzan must not be allowed to escape from the Tang Dynasty.

Li Er did not wait for the news of the capture of Tubo Da Lu Dongzan, but the accident was equal to the news sent by Liu Yuan, after a little thought, he immediately made a handwritten instruction, and asked people to send it back with an expedited horse of 800 miles, and after the letter was sent out, he did not rest, and immediately asked the eunuch to gather the group of important ministers to start discussing how to deal with Tubo

The sun is shining, the autumn wind is blowing, rolling up the yellow leaves on the ground, and the surroundings are silent and lonely.

Guan Yong snorted his hand with his mouth, tightened the sheepskin jacket on his body, shrunk his neck, turned his head to Liu Yuan, who was hiding on the grass and chewing beef in his mouth, as if looking at the clouds in the sky, and said in a low voice: "General, why is this place where birds don't so cold?" In Songzhou or autumn, how do you feel that when you come, it is colder than Chang'an in winter? ”

"It's very simple, it's normal for the sea to be high and the temperature to be low here." Liu Yuan said lazily.

At this moment, Liu Yuan felt that he was like a nanny, or a big nanny, protecting this group of subordinates, although he was determined to enter Tubo and do something good, but Liu Yuan knew that he couldn't eat hot tofu in a hurry, himself, the wild wolf, the blood knife plus the fifty subordinates, a total of fifty-three people. However, Duan Zhixuan deducted Cheng Huailiang, and there were fifty-two people, like Liu Yuan, Wild Wolf, Blood Knife, Zhao Fu and others, a total of seventeen people in the team had experience in the plateau, and they were not afraid of altitude sickness, and the remaining thirty-five people, including Guan Yong and Hou Jun, were still in Tubo for the first time. Step by step, move towards the skull.

At the beginning, ten of the thirty-five people had altitude sickness, and two of them were so severe that they couldn't even breathe, so Liu Yuan gave them some medicine that could help reduce altitude sickness while transferring them back to a lower place in the sea. Along with altitude sickness, high fever, cough and other illnesses appear. Fortunately, Liu Yuan and others have rich experience. The medicine is also well prepared, and they are well taken care of, and these days, while taking care of them, guarding against the Tibetan patrols, and taking care of their daily life, etc. It's not a waste of effort.

Fortunately, the Tubo area is sparsely populated, and Liu Yuan is familiar with this area, and there are only more than 50 people, and it is easy to hide. With the help of clairvoyance, they were able to discover the enemy in advance, so after more than ten days in a row, they were all right, and after more than ten days of field training, those present had initially adapted to the plateau climate, but the two were seriously unadaptable, and they also gritted their teeth and followed, although they were weak, but the disease did not recur.

Guan Yong asked curiously, "General, what is Haipai?" ”

The soldiers next to him also looked at Liu Yuan curiously, because they often heard a lot of new and interesting things from Liu Yuan's mouth, and now they said that there was something to do, which suddenly raised everyone's interest.

"Sea dial is a term, we live here, there are high mountains, there are deep valleys, but how high the mountain, it is difficult to find a standard, this sea dial is based on the sea as the plane, how much higher is how much the sea dial, how to see this one by one? Can't get it? If you don't understand it, you just know that it's a term. Liu Yuan didn't bother to explain, with the current level of science and technology in Datang, it is difficult to explain, even if it is explained, they will ask, the mountain is here, and the sea is thousands of miles away, tens of thousands of miles away, how to measure?

Everyone nodded as if they didn't understand, and Guan Yong asked curiously: "General, just now you said that the sea is high, and the temperature is at the bottom, is there really such a statement?" ”

"It's true, haven't you noticed? Usually the temperature at the top of the mountain will be much lower than at the foot of the mountain, and you will see it in the hinterland of Tibet, some very high mountains, the foot of the mountain is full of spring flowers, and the top of the mountain is covered with snow all year round, about every 100 meters it drops to 0.6 degrees, and 100 meters is equivalent to about 33 zhang now. ”

Zhao Fu also heard this statement for the first time, and couldn't help but say curiously: "General, is this 0.6 degrees more or less?" ”

"For example, when boiling water, it is about 100 degrees, and a normal person's body temperature is about 37 degrees, if a person feels hot, then the temperature is close to or higher than this degree, and if it is cold, it is the temperature of 37 degrees, then you need to add clothes." Liu Yuan patiently explained.

When everyone heard this, they nodded one by one, and Niu Shiming asked a little curiously: "General, your knowledge is really profound, then do you know how high the highest mountain in the world is?" Is it true that you can reach the sky, climb to the end, and you can go to heaven? ”

"To heaven?" Liu Yuan said disapprenorovingly: "As far as I know, the highest mountain in the world is in the territory of Tubo, about less than 3,000 zhang high, what reaches the sky, that's just a rumor, if you climb up, you can't go to heaven and don't know the way, but you can be sure of one thing, then you can prepare for the future." ”

The generals laughed loudly, but it's right to think about it, now everyone is hiding in a valley near Jishi Mountain, which can be regarded as half a waist on the Tubo Plateau, but there have been so many reactions, the more up it is, the more uncomfortable it is, at the beginning there is nothing to do, the more you go up, the greater the pressure, as if you are dozens of years old all of a sudden, and you have to take a breath when you take a step.

"General, a few puffs of wolf smoke suddenly rose in the territory of Datang, one will be extinguished, and the other will be extinguished, which is very weird." At this time, Hou Jun, who was in charge of guards, held a clairvoyant hand and ran to report to Liu Yuan.

Hou Jun is one of the two severe altitude sickness patients, fever and vomiting, it took three days to come back to his senses, originally Liu Yuan asked him not to go, go home, but Hou Jun refused to live or die, saying that his uncle Hou Jun Ji can, as a member of the Hou family, it must be okay, rather die than retreat, gritting his teeth and forbearing, I didn't expect him to survive the adaptation period with the help of medicinal materials, and now he can keep up with the team, in order to prove that he will not embarrass the old Hou family, and now he also takes the initiative to undertake the vigilance task.

It's all good.

Wolf smoke?

Liu Yuan's heart moved, took the clairvoyance, climbed the hill, raised the clairvoyance, and looked in the direction of Datang, only to see that in the direction of Songzhou, there were three black and straight wolf smoke, rising to the sky, which made people feel surprised, these three wolf smoke did not rise all the time, extinguished for a while, and rose again and again, over and over again, as if passing on some news, of course, this is only Liu Yuanzhi said.

While watching, he counted silently in his heart, and soon, a satisfied smile appeared on Liu Yuan's face.

This is a signal agreed between Liu Yuan and Li Er, Li Er agreed with Liu Yuan to send troops to Tibet, that is a signal, if you disagree, it is another signal, Liu Yuan is leading them to adapt to the plateau time, just waiting for Li Er's opinion, after all, the Yangwei Army is not Liu Yuan's private army, rashly dispatched, was greedy by the villain, and burned himself before he made meritorious service, what should he do with his wife and concubine in his own family? If something really happened, people like Hou Junji and Niu Jinda can spare themselves?

Fortunately, the message conveyed by the wolf smoke is that Li Er has agreed to Liu Yuan's plan and action, and this time, the division is famous, justifiable, and not afraid of criticism.

Putting away the clairvoyance, Liu Yuan turned his head to Zhao Fu and shouted: "Zhao Fu"

"Subordinates" Zhao Fu's expression was grim, he knew that when Liu Yuan made a move, he spoke in this tone.

Liu Yuan said with a serious face: "I order you to lead a fire man, pull all the horses we left in the territory of Datang here, remember to clean up the traces, and in addition, find some planks and carpenters for me for me, it will be of great use, and the speed should be fast." ”

"Yes, General." Zhao Fu responded, and then said a little strangely: "General, what do you want a plank for?" Still need a carpenter's tool? Did you hear that right? ”

"If you want to go, then what are you doing wordy?" Liu Yuan waved his hand and said, "Ben will have its own wonderful use, you just need to execute it." ”

"Yes, General, the little one retires." (To be continued......)
