The Turks are divided into two parts, of which the eastern Turki occupy the northern steppe of the Tang Dynasty, also known as the grassland Turkic, was destroyed by Li Shimin World War many years ago, and now there are almost no Turks on the grassland, while the western Turkic occupies the western region, the strength is also very strong, once with the Tang alliance to deal with the eastern Turks.

But since the annihilation of the yixian by the Tang, perhaps the fate of the West Turkic, the West Turkic also began a rapid decline, said the West Turkic recession reasons for a lot, but the most important point is the internal war, since the original protection of the Ye Khan after the death, the entire West Turkic interior on the war, the size of the sweat force self-weight, the western region also became a mess.

In the case of civil unrest in the West Turkistan, Datang will naturally not let go of this excellent opportunity, so these years, Datang has also been expanding its influence to the western region, many small countries in the western region have also turned to Datang, a time when the influence of the Tang in the western region increased, and the western region is the only place of the Silk Road, so the Tang even began to stationed in the western region, further vaping the West Turkic territory in the western region.

In the face of the advance of the Tang, the undisturbed West Turk is also unable to resist, and even in order to win the support of Datang, but also deliberately with the Tang, some small khans even for some self-interest, directly the West Turkic original territory, but also to promote the ambition of the Tang, according to this situation development, I am afraid that in a few years, the entire western region will fall into the hands of the Tang.

However, this situation has suddenly undergone some changes this year, the original West Turkic internal division is serious, there are two of the most important forces, namely the North Court and the South Court, and in this spring, the northern court of Evifang Luo khan defeated the southern court of the feminine yip of the y viti 撵�叶 to protect the khan, the result of the northern court strength soared, the western Turkic khan also has a unified trend.

With the increase of strength, the northern court of B vili Lu Khan is also self-confidence soared, in the face of the Tang step by step, no longer blindly give in, but he is at least a little rational, know that even if he unified the West Turkic, in the face of the big Tang this behemoth is still no advantage, so he did not dare to come forward, even instigating Gao Chang to the Tang provocation.

Now Gao Chang Wang named Qi Wentai, a few years ago also visited the Tang, when he was not very good at the Tang attitude, but in order to express their own measurement, Li Shimin did not care too much, but also rewarded each other.

Unfortunately, Li Shimin's practice not only did not get the gratitude of Qi Wentai, but let him feel that the Tang is weak and defied, more contemptuous of the Tang, and Gao Chang is located on the great road of the Silk Road, almost all the group of shops must pass through Gaochang, but often some of the group encounters "bandits" attacks, it is said that these "bandits" training, the past, but the top of the terrain is known, each time the Tang.

Of course, although Guo Wentai is stupid, but he is not stupid and hopeless, he knows the gap between Gaochang and Datang, so he generally will not touch the bottom line of Datang, and he also relies on it, that is, Gaochang is far away from Datang, even if Datang wants to attack Gaochang, it is not an easy thing.

However, with the strength of the northern court, Gao Chang is also very close to the northern court, just this summer, the northern court of Bili Lu khan to lure Qi Wentai, the two sides alliance together to attack, and the rut is one of the small countries in the western region and the Tang, and even intends to become the vassal country of the Tang Dynasty, but did not expect to be the northern court of the Turks and high annihilation, and then the emperor.

In fact, the northern court Turks this time is to test the bottom line of the Tang, if the Tang on the demise of the Tang regardless of the demise of the Tang, then there will certainly be more small Western countries annexed by the West Turkic, then the efforts before the Tang will also be destroyed.

So when the envoys who were asking for help arrived in Datang, the courthouse was also noisy, and many people supported the army in the western region, giving the northern court a hard lesson to let them know who was the master of the western region!

However, some reasonable ministers believe that the court has just sent troops to destroy Gao Yili, this war consumes a lot of manpower and material resources, even now Datang has not been able to fully recover, and successive foreign wars, will also make the outside world have a kind of warful impression of Datang, which is also not conducive to the rule of the small countries around the Tang, so they also reported a very cautious attitude to the matter of the Western region.

This matter is not only quarreling in the court, but also quarrels between readers, and finally South College and Nanshan College are the gathering places for young readers of Datang, so the discussion of the western region here is also more lively, many young people have expressed their opinions, and even wrote long posts on the bulletin wall of the college, on the one hand to express their views, on the other hand, they can also use this to make their own name.

In this environment of the college, Li Xiu thought that it was impossible to know that the Western region was impossible, and even some students took advantage of the class to ask Li Hu about his views on the matter, which made him simply avoid this matter, and asked him to understand more about it.

In fact, for this matter, Li Huo's view is very simple, that is, must send troops, because the location of the western region is too important, even if the development of the current high-level maritime trade is good, the Maritime Silk Road is also very smooth, but the land Silk Road is also equally important, if the Western region is lost, the Silk Road will be in the hands of others, which will have a major impact on the business of Datang, and even blow, so we must fight the northern court's atmosphere.

But now Datang also does have concerns, on the one hand, just after a great war, the national strength has not been restored, on the other hand, the northern court of the Turkic has a trend of unifying the West Turkic, if now with the other side to tear the skin, in the future if he really unified the West Turk, it will pose a great threat to Datang.

In particular, the second half of the Silk Road is also in the hands of the West Turkic, so if the Tang really and the West Turku tore the skin, it must win, like the former eradication of the yavior and the West Turkic, so as to destroy the West Turkic, so as not to affect the operation of the Silk Road, but now Datang obviously does not have this strength, after all, the western region is too far away, the army's grain and grass transport is a big problem.

In the face of this situation, Li Hu can not help but feel a headache for Li Shimin, whether it is to send troops or not to serve, it seems to make Datang into some trouble, and now the internal problems of Datang, it is more difficult to make people choose.
