After the ministers of civil and military affairs withdrew, only Li Shimin and the people he named to stay were left in the main hall. Li Su is still lying on the stretcher, and there are Li Jingheng and Yanbei as companions just now, so he doesn't feel anything, but now he is lying alone, he wants to stand but doesn't dare to stand, and when he lies down, he feels that everyone's eyes are on him, not to mention how uncomfortable it is.

Li Shimin asked Li Ke and Li Su to stay, but he ignored them anymore, but said to Li Jing and others: "Tubo is now full-fledged, and he has always been rude to my Tang Dynasty, today the Tubo ambassador was beaten by these juniors, with the arrogance of Tubo in the past, he will definitely not swallow this breath, how do you think you should deal with it?" ”

"Your Majesty, Tubo has been arrogant for a long time, and my Datang must not back down on this matter Chapter 32 Tubo's proposal and road construction, so Weichen expects that he will definitely raise troops to invade my Datang in the future, so I hope Your Majesty will make plans as soon as possible." Fang Xuanling came out first and said.

"What Fang Xiang said is good!" Li Jing, the Duke of Weiguo, also stood up and said, "If Tubo raises troops, it is very likely to march from Jiannan Road, which belongs to the southern Xinjiang of the Tang Dynasty, and the troops are already weak, and it is close to the six edicts in the south. ”

"Well, what the two Aiqing said is reasonable, it seems that my Datang is ready to use force with Tubo." Li Shimin's mind is also very sober, and he agrees with Fang Xuanling and Li Jing's analysis. Lying on the ground, Li Jing admired Li Jing even more, and he remembered that the first battle between Tubo and the Tang Dynasty was in Songzhou, Sichuan, which was indeed very close to Tubo and the Six Edicts.

"Hou Qing, as the secretary of the Ministry of War, you will introduce the current situation in Tubo!" Li Shimin pondered for a while, then turned his head and said to Hou Junji again. Hou Junji was the secretary of the military department at that time, and the collection of enemy intelligence was within his purview.

"Yes, Your Majesty!" Hou Junji, who looked fierce with tiger eyes and eagle nose, stood up and said: "Tubo is located in the southwest of my Tang Dynasty, Chapter 32 Tubo Discussion and Road Construction and my Longyou Road are only separated by some Qiang tribes, the northeast of the country is Tuyuhun, and the southeast is the Six Edicts. After Songtsan Gampo succeeded to the throne, the capital was moved from Shannan Pibo to Luo, annexed Subi and Yang, and broke the party and Bailan, defeated Tuyuhun and obtained its old land, and the strength was extremely strong, although it was not as good as the ** in its heyday, but it was also an enemy that should not be underestimated......

Hou Junji talked eloquently to the people in the palace, mainly from the military aspect to introduce the situation in Tibet. Li Su probably listened to it, and was very disappointed in Datang's intelligence system, what top-secret information could he have heard since then? Who knew that Hou Junji talked for a long time, and it was all about military information, such as the military strength of Tubo? How powerful is the army? Who are the main generals? There is almost no valuable information on the general situation of the distribution of troops, etc., as for the domestic people's livelihood, politics, economy, etc.

Hou Junji spoke for a long time, and finally took a sip of tea and added: "In addition to the strong military strength, Tubo also occupies a geographical advantage, because of its extremely high terrain, the border with our country is very steep, most of them can not let the army pass, and a few passes, and there are heavy troops of Tubo, which can be said to be easy to defend and difficult to attack. ”

Speaking of this, Hou Junji hesitated for a moment, seemed to think of something incomprehensible, thought for a while, and then continued: "And I have heard people who have been to Tibet say that in addition to the native Tubo people, it is difficult for outsiders to adapt to the climate of Tibet, for example, there are some Tang caravans, once they enter the territory of Tubo, many people in the caravan will have headaches, dizziness, tinnitus, general fatigue and other symptoms, and people will also become very fragile, a small wind chill may kill people." ”

"Oh? Is there such a thing in the world? Li Shimin asked hesitantly, and the other civil and military ministers had heard of this kind of thing for the first time, and they all whispered about it.

"Your Majesty, this matter is true, the Tubo people once boasted that it was their great god blessing, so that Tubo has an additional natural barrier, with this barrier, even if there are thousands of troops and horses, it will not allow other countries to step into Tubo half a step!" Hou Junji replied with an affirmative face.

"Although the things of ghosts and gods are absurd, they must not be believed...... Li Shimin was silent after speaking, looking very entangled, and the other ministers were also at a loss. The Tang royal family claims to be the descendants of Lao Tzu Li Er, so they are very respectful of Taoism, and most of the upper-class nobles believe in Taoism, and the most legendary things in Taoism are things like immortal immortality. In order to seek immortality, many princes and ministers are refining pills and serving pills, even Li Shimin is no exception, there are many Taoist priests in the palace, and occasionally refining some pills for him. Therefore, although Li Shimin does not fully believe in the matter of ghosts and gods, he does not believe in it.

"Father, this is not a ghost or god protection at all, it's just a boast of the Tibetan people!" At this moment, Li Su, who was lying on the stretcher, suddenly stood up and said.

He suddenly figured it out just now, the scene he played was probably seen through by Li Shimin and others a long time ago, but he didn't expose them to their faces, and it was probably Li Shimin's intention to let him lie down like this. He is worried that he has no valid reason to stand up, and he can't admit to himself that I am pretending? At this time, when he heard that Li Shimin's gang was dazed by a altitude sickness, Li Su was overjoyed in his heart, and simply cheeked up, anyway, he was underage, and it was normal to play a little scoundrel.

"Oh? Tell me about it! Li Shimin was stunned at first, originally he left Li Ke and Li Su with another deep meaning, but he didn't expect Li Su to dare to expose his lies and stand up, but after all, he is an open-minded emperor, and now his attention is on Tubo, and he doesn't care much about Li Su's subtleties. The other ministers of civil and military affairs were also stunned, and they probably didn't expect Li Su to speak!

"Father Qi, what Lord Hou said about outsiders not being able to adapt to the climate of Tibet is indeed true, but it is not so mysterious, it is almost worthless to put it bluntly, and it is not impossible to overcome." Li Su said confidently.

"Oh? The old minister is ignorant, and he also asks His Royal Highness King Liang for advice! Hou Junji asked with a somewhat ugly face, after all, he is the secretary of the Ministry of War, in charge of the military intelligence of the entire Tang Dynasty, and even he didn't figure out the things, Li Su would know, and he also devalued it worthless, which made his face not very good-looking.

"Hehe, don't dare to give advice, Lord Hou has collected quite complete information about Tubo, Li Su admires it very much!" Li Su said with a smile to Hou Junji, although what he said was a little against his will, but Li Su was also helpless, now his strength is too weak, it is really not the time to offend people, having an eldest grandson Wuji has made him uncomfortable enough, he doesn't want another Hou Junji to look at him unpleasantly.

Hou Junji is very proud, but he is not angry with the fourteen or fifteen-year-old Li Su, and after hearing Li Su's praise, his face immediately looks much better.

Li Su breathed a sigh of relief and continued to speak: "In fact, what Lord Hou just said about a series of discomforts caused by outsiders entering Tibet can be collectively referred to as altitude sickness. ”

"Altitude sickness? Plateau? Could it be that it has something to do with the topography? Wei Guogong Li Jing muttered to himself a few times, and suddenly his eyes lit up, as if he had thought of something.

"Wei Gong is really powerful, just by this name, I thought of the key, and he is worthy of being the first person in my Tang Army!" Li Su praised that for Li Jing, a legendary figure, Li Su admired it from the bottom of his heart.

Hearing Li Su call Li Jing 'the first person in the army', those unruly generals turned out to have a natural expression, even Hou Junji, who regarded himself very highly, was no exception, which shows Li Jing's prestige in the army. However, it is no wonder that Li Jing retired early, and now he is only acting as a military adviser and other roles, and is not in charge of actual military power, after all, no matter how magnanimous Li Shimin is, he definitely does not want a figure in the army who can threaten his emperor's identity.

"Hehe, His Royal Highness King Liang has praised it falsely, where is the old man called the first person in the army?" Li Jing stroked his beard and smiled, he didn't pay much attention to Li Su after the last Five Kings Banquet, but after his careful observation today, he was very surprised in his heart, whether it was demeanor, temperament, or knowledge, there was almost no one comparable among the younger generation he had seen, and even Li Ke, who he had always been optimistic about, was now standing next to Li Su like a foil, where was this still the prince from before?

"Haha, the pharmacist is polite, who doesn't know that you use soldiers like a god, if it weren't for the help of you and the Qing family, where would I be prosperous now?" Li Shimin also said with a smile, and by the way, he praised everyone present, and then turned his head to look at Li Su and said, "Su'er, you should quickly talk about what 'altitude sickness' is, and what can be done to solve this problem." ”

"Yes, Father!" Li Su bowed and said, "The so-called altitude sickness, in fact, simply put, is mainly because Tubo is located on the plateau, and the air is much thinner than the plain area. ”

"This ...... How simple is it? Hou Junji's face was incredulous, in order to figure out this matter, their military department spent a lot of manpower and material resources, but in the end, it was still just a ghost and god theory.

At this time, the British Duke Li Ji also suddenly stood up and said: "His Royal Highness King Liang said this, this reminds the old man that when he was young, I went to visit friends in the high mountains, but I didn't expect to fall ill just one day, at first the symptoms were almost the same as what Lord Hou said, and then the illness worsened and almost died, my friend hurriedly carried me down the mountain, and after a few days of recuperation, I was cured, I guess it was altitude sickness, right?" ”

"That's right, as long as it is more than a certain height, after the people who live in the plains all the year round enter, according to each person's physique, there will inevitably be a variety of different reactions, but some people's reactions are very weak, and even I don't notice it, and some people have strong reactions, if they don't deal with it in time, they even have to worry about their lives, and the best way at this time is to quickly return to the plains like the British duke, and rest for a few days and it will be fine." Li Su said again.

"Good!" Li Shimin took the case, "If it is really as Su'er said, then as long as I Datang finds a station in Tubo and sends troops to adapt to the climate there first, why should I be afraid of Tubo children at that time?" Hahaha~"

It is estimated that he thought of the feat of stepping on Tibet in the future, Li Shimin looked up to the sky and laughed, and spit out the stuffiness in his chest. The civil and military ministers below are also talking, especially those generals, most of them have joy on their faces, and now they are finally going to fight again. Most of the Wenchen frowned and pondered, as if they were weighing the gains and losses of the war with Tibet. However, whether it was a civil servant or a military general, the eyes that looked at Li Su at this time were filled with a hint of admiration.

The eldest grandson Wuji in the crowd had been looking at Li Su coldly, and only then did he suddenly speak: "Your Majesty, although the Tubo army is strong, but for my Datang, it is just a group of chickens and dogs, but the army has not moved the grain and grass first, if the army is in Jiannan and Tubo Xingjun, the first thing is to solve the problem of grain and grass, Jiannan Road is under the attack of Tubo and the Six Edicts, although it is rich, but the traffic is blocked, it cannot support too many troops stationed, if the two armies confront each other, it is extremely unfavorable for my Datang." ”

If the eldest grandson Wuji is a basin of cold water that fell on his head, he immediately sobered Li Shimin up. Jiannan Road includes most of the Sichuan Basin in later generations, as well as part of Yunnan, Guizhou and Gansu, although the Sichuan Basin is rich, but it is surrounded by mountains, and it is rainy there, the road is extremely rugged and difficult to travel, and the army of the Tang Dynasty wants to enter there, and it is estimated that the cost is extremely huge.

Li Shimin pondered for a while, then suddenly turned his head to Fang Xuanling and asked, "Fang Qing, I remember that the year before last, Jiannan organized the people to overhaul the road, and now the traffic situation has improved?" ”

"This ......" Hearing Li Shimin mention this matter, Fang Xuanling smiled bitterly, "Your Majesty, the year before last, Jiannan did organize hundreds of thousands of people to build roads, but it was rainy in the south, and the roads that had just been repaired were washed away by the rain, and they immediately became muddy and difficult to walk. ”

In ancient times, it was rammed earth for the road, and the most afraid of rain washing, the Vermilion Bird Street in Chang'an City was paved with bricks and stones, but this is just a street, if the roads of the Tang Dynasty are paved with bricks and stones, it is estimated that even if the Tang government is bankrupt, it will not be completed.

"Sizzle~" After hearing Fang Xuanling's words, everyone here gasped, the roads built by hundreds of thousands of people were all washed away by the rain in less than two years, they only knew that there was a lot of rain in the south, but they didn't expect it to be so powerful.

Li Jing stood up again at this time and said: "Actually, Lord Changsun is too worried, compared with my Tang Dynasty, Tubo is much worse in every aspect, so the old minister expects that even if Tubo invades my Tang Dynasty this time, it will definitely be just a temptation, and I dare not fight to the death with my Tang Dynasty, so I only need to send an elite army to defeat the arrogance of Tubo, and then Tubo will definitely retreat." ”

I have to say that Li Jing's vision is vicious, and he can see the general trend between the Tang Dynasty and Tubo at a glance, and the Tubo people absolutely do not have the courage and strength to fight to the death with the Tang Dynasty, so the first battle between Tubo and the Tang Dynasty is destined to be just a temptation.

As far as he knows, the battle of Songzhou between the Tang Dynasty and Tubo, 200,000 Tubo soldiers invaded the Tang Dynasty and surrounded Songzhou, but later the reinforcements of the Tang Dynasty arrived, after killing thousands of Tubo troops, the Tubo people immediately retreated, and Songzan Shibu wrote a confession to admit his guilt, and a fierce battle of Songzhou ended.

"Hahaha~, the hero sees the same thing, I think so too!" Li Shimin stroked his palms and laughed, but soon his face turned worried and said, "It is easy to defeat the arrogance of Tubo, but this battle has also exposed the emptiness of Jiannan Dao's troops, I am afraid that in the future, as Tubo's strength increases, there will be disagreement with Jiannan Dao again, it seems that it is only right to strengthen the connection between Jiannan and the Guanzhong region, but this road is ......."

When Li Shimin said this, his brows were tightly wrinkled together, and the ministers below were also at a loss, building roads is not a problem, the problem is that they can't be used soon after repairing, and a lot of manpower and material resources are spent on useless work, and Datang's treasury can't withstand such consumption. In fact, not only Jiannan, but also the Tang Dynasty south of the Yangtze River have road problems, everyone knows that the south is rich, but traffic has always been a big problem, after all, no matter how much production is produced, it is useless if it cannot be transported.

"Father, the son has something to offer, which can solve the road problem!" At this time, Li Su suddenly stood up and said, looking at the sad face of the Tang Dynasty monarch and minister who was made by a road problem, Li Su laughed secretly in his heart, this little thing is really a piece of cake for him, a modern person, and it can not only please his cheap father, but also make a fortune, it is simply a double win!!.
