At the end of the Sui Dynasty and the beginning of the Tang Dynasty, there were numerous Wuman and Baiman tribes and tribes around the Erhai Lake in Dali, Yunnan, and in the northern areas of Ailao Mountain and Wuliang Mountain. These barbarians were almost the descendants of Meng Huo, king of the Southern Barbarians during the Three Kingdoms period. . Among these numerous barbarians, there are six most powerful Wuman tribes, whose names are: Mengshe, Mengqi, Langqiong, Dengxi, Shilang and Yuexi, which are known as the "Six Zhaos" in history. "Zhao" means king. Mengshe Zhao is located in the south of all Zhaos, so it is also called Nanzhao. Among the six imperial edicts, the Mengxi and Yuexi imperial edicts had the largest territory and the strongest soldiers. However, the Mengshe imperial edict that later unified the six imperial edicts and established the Nanzhao Kingdom was at this time more powerful than the two imperial edicts of Mengxi and Yuexi. weak. The main reason why the weaker Meng Shezhao became stronger and stronger in the long-term struggle with other tribes was that it received the support and help of the Tang Empire! The chief of Mengshe Zhao was named Meng, and his ancestor was named Shelong. At that time, in order to avoid his enemies, he led his people to move from Ailao to Mengshechuan. Shelong gave birth to a son named Longduluo, also known as Xinuluo. During the Taizong period, Zhang Lejin, the chief of Mengshe, petitioned the Tang Dynasty to give up his throne to Xinuluo. Zhang Lejin is from the Baiman tribe, while Xinuluo is the leader of the Wuman tribe. The reason why Zhang Lejin gave up the throne at that time was probably because there were few Baiman people and their survival was threatened by the Wuman people. At that time, the Tang Dynasty was not long after its founding and was busy fighting the Turks in the north, so it had no time to estimate the internal struggles of a group of barbarians in the southwest. Naturally, it agreed to Zhang Lejin's request and named Xinuluo the leader of the Mengshe tribe. After Xinuluo became the leader of Meng Shezhao, he established the "Great Mongolian Kingdom". Calling himself "King Qijia", his ministers belonged to the Tang Dynasty and sent envoys to pay tribute. Emperor Gaozong appointed Xinuluo as the governor of Weizhou. When Wu Zetian arrived, Xinuluo also sent his son Luo Shengyan to Chang'an as a hostage. During this period, other Wuzhao and Heman tribes except Mengshe were often invaded and threatened by their evil neighbor Tubo in the northwest, so they often abandoned the Tang Dynasty and joined Tubo. Nanzhao always attached itself to the Tang Dynasty and thus received the support of the Tang Dynasty. Later, Meng Lian, He She and others led their troops to rebel under Meng Si's imperial edict, so the Tang Dynasty appointed Li Yi as the general manager of Yaozhou Road. He led troops to attack Meng Lian and other rebel barbarians. In the Xianheng period of Emperor Gaozong. The Tang Dynasty appointed Wang Renqiu, the chief of the Xicuan tribe, as the commander-in-chief, and finally put an end to the chaos. If it weren¡¯t for the fact that Mengshe Zhao was far to the south, separated from Tubo by numerous other tribes, and was often invaded by several other large tribes. I'm afraid Nanzhao would not have been so submissive to Datang at that time. Because other imperial edicts were not friendly enough to Datang. Datang naturally paid more attention to its relationship with Meng Shezhao. He even gave the land of Yangguazhou to Meng Shezhao for nothing. After Li Longji ascended the throne, he continued to support the Nanzhao tribe and named Pi Luoge, the leader of Nanzhao, as the Taideng County King. The following year. Piluoge sent his adviser Zhang Jiancheng to Chang'an to express his loyalty, which pleased the emperor. In the twenty-fifth year of Kaiyuan, when the soldiers of the Tang Dynasty fought with the Tubo Kingdom near Qinghai Lake, Piluoge took the opportunity to send troops to Taihe City and defeated the old enemy Heman tribe in one fell swoop. Because the relationship between the Tang Dynasty and Tubo was very deteriorated at that time, and the two families were fighting life and death in the Longyou area, so Piluoge led his troops to attack the Heman tribes who were leaning towards Tubo, which had a sense of containing Tubo. Therefore, at the beginning of the twenty-sixth year of Kaiyuan, Li Longji, who had just won a great victory over Tibet, was very proud, and he also rewarded Piluo Ge. He gave Piluo Ge the Chinese name of Meng Guiyi and was knighted. King of Yunnan. In the book made by the Tang Dynasty to grant the title of king to Meng Guiyi, the reason for the title of king was clearly written: "The tribes of the Erhe River infiltrated the Quanrong (Tubo), and Meng Guiyi led his troops to conquer with meritorious service." Piluo Pavilion After receiving the reward from Datang, he was naturally overjoyed. He immediately held a secret discussion with his adviser Zhang Jianchun, planning how to use the power of the Tang Dynasty to take advantage of the situation and annex the other five imperial edicts. Zhang Jiancheng then suggested to Piluo Ge that he send someone to send a heavy gift to Wang Yu, the envoy of Jiannan Jiedu, and then ask Wang Yu to say something good to the court on behalf of Mengshe Zhao, and suggested that the six Zhaos should be merged together and become a subordinate state. The barbarian tribes of the Tang Dynasty. Pi Luo Ge felt that Zhang Jiancheng's idea was a good one, as it could hide his ambition well and achieve the goal of annexing the other Five Zhaos through the mouths of the Han people, so he immediately prepared an astonishing amount of treasure and had it secretly given away. It was given to Wang Yu, the Jiedushi envoy of Jiannan. Wang Yu, a short-sighted guy, received a huge benefit from Piluo Pavilion. He immediately wrote to the court, trumpeting Meng Guiyi's commendable loyalty and the huge benefits after merging the Liuzhao. In the end, he really got Li Longi¡¯s permission. In fact, Li Longji's strategic vision is not that superficial, and he is not so easily fooled by Wang Yu. The emperor wrote to Wang Yuzhi: Meng Guiyi loyally contributed to the crusade against the Western Barbarians, and he (referring to the remaining five imperial edicts) held both ends (one of them attached to the Great Empire).?, and soon fell to Tubo), so it should be broken." In other words, the emperor did not recognize the benefits of the unification of the six imperial edicts, just because he hated Tubo, and at the same time he also hated Mengsi, Langqiong, The five tribes of Deng Xun, Shi Lang and Yue Xi were extremely disappointed, so they hoped to use the power of Meng Shezhao to clean up all the minions attached to Tubo! Because sending troops to assist Meng Shezhao in crusading the other imperial edicts was of great importance, and the imperial court was very concerned about it. There were many disputes, so it was difficult to determine for a while who to send to supervise the army. Although Zhou Ziliang, the censor Zhongcheng, could not directly participate in the military affairs, according to the past practice of the imperial court in sending troops, the emperor would definitely send an eunuch and an eunuch. A censor went to supervise the battle, so he immediately wrote the whole story in detail in a secret letter and sent it to the Shenwei Army immediately. After receiving his father's secret letter, Zhou Chengye took it very seriously and immediately wrote a reply to Zhou Ziliang. Feng. In this letter, Zhou Chengye clearly stated his attitude, that is, the Tang Dynasty should not let tigers become troubles! Tuesday, from later generations, knew better than anyone else what the Tang Dynasty had caused by sending troops to help Piluo Pavilion attack the other five imperial edicts. Disastrous consequences. Pi Luoge, whose name is Meng Guiyi, is actually an ambitious guy. Once he unifies the Six Zhaos, there will be a very cunning and cruel enemy in the southwest of the Tang Dynasty. The Nanzhao Kingdom in history! , initially attached to the Tang Dynasty. After its wings became stronger, it began to covet the land in the southwest of the Tang Dynasty. In the end, it fell to the Tang Dynasty's enemy Tubo without hesitation. The consequences he had sown with his own hands were that during Li Longji's lifetime alone, more than 200,000 soldiers of the Tang Dynasty were killed in the campaign against Nanzhao! Moreover, it was precisely because the Tang Dynasty devoted its limited troops to external expansion and expansion! During the crusade against Nanzhao, when An Lushan and Shi Siming in the northeast raised their flags to rebel, there were no soldiers in the hinterland of the Tang Dynasty. They watched helplessly as An Lushan and Shi Siming led the army to attack Luoyang. , and then destroyed the imperial capital Chang'an. Zhou Chengye may not dare to tell others about these memories from later generations, but he has no worries about his own father, Zhou Ziliang, in this letter. He described to his father the great harm that would be caused to the Tang Dynasty after the unification of Meng Shezhao. Zhou Ziliang's back felt cold and cold sweat broke out on his forehead. Originally, Zhou Ziliang also agreed with the Tang Dynasty to send troops to help Meng Guiyi conquer the rest. After the test of many major events in the past few years, Zhou Ziliang now has no doubts about his younger son's almost evil-like judgment and prediction, since Erlang repeatedly emphasized the huge hidden dangers after the unification of the Six Zhaos. That means that this matter cannot be done, otherwise it will be the terrible result that Erlang assumed. Zhou Chengye also gave his father advice in the letter, suggesting that his father secretly contact Zhang Jiuling, Li Yi, Du Hope, Li Jing and Niu Xianke. A group of heavyweight ministers and princes came forward to dissuade the emperor. Even if they sent troops to attack Wu Zhao, they would directly send troops to garrison after the war instead of giving the land they had worked so hard to conquer to Mengshe Zhao. If this Tuesday¡¯s suggestion could be summed up in one sentence, it would be to change from ¡°driving the tiger to devour the wolf¡± to ¡°attracting the wolf into the house¡±! In Pi Luoge¡¯s eyes, the Tang Dynasty was a brainless tiger, and his method of using the Tang Dynasty¡¯s soldiers to annex the other six imperial edicts was to ¡°drive the tiger and devour the wolf.¡± But if the Tang Dynasty only defeated three Wuman tribes after sending troops, and then supported two obedient tribes to stand up and play "Three Kingdoms" with Meng Shezhao, wouldn't it be tantamount to inviting a wolf into the house? Of course, after the Tang Dynasty sent out troops, if they wanted to hit wherever they pointed and still stand firm after the battle, this required very good command and balance skills. Obviously, expecting Jiannan Jiedushi Wang Yu, who had been bribed heavily by Piluo Pavilion, to send troops to fight was tantamount to seeking the skin of a tiger. Since Wang Yu is no longer reliable, let¡¯s find a way to capture him! On Tuesday, he clearly told his father in the letter that Wang Yu had secretly accepted a huge bribe from Pi Luoge. As long as this matter was verified, the honeymoon period between Datang and Meng Shezhao would be over immediately! Although there is no evidence to prove Zhou Chengye's "exposure" at this time, Lord Zhou Ziliang, the censor Zhongcheng, chose to believe his son without reservation. In these years, if this son who is so wise and almost evil has not worked hard, how would he have the position of the censor Zhongcheng, and where would the eldest son have the position of the official secretary of the Ministry of official affairs! When Wang Yu, the envoy of Jiannan Jiedushi, submitted a memorial to the court suggesting that the six imperial edicts should be combined into one, and it was delivered to Chang'an half a month later, the imperial court agreed to send troops to help Meng Shezhao attack the remaining five imperial edicts. The voice became louder and louder. On this day, the emperor met with the heavyweight officials in Beijing at the Zichen Palace and decided to make a decision in the hall about sending troops to attack the Five Emperors. Zhang Jiuling, who was already in a semi-retirement state, suddenly took the wrong medicine and was the first to stand up.When he spoke, he actually opposed the Mengshe imperial edict's annexation to the other five imperial edicts. He was closely followed by Li Yi, the former Minister of War. This old guy said almost the same thing as Zhang Jiuling, but his tone was more intense. Then, before Li Linfu, the current minister of the Ministry of War, opened his mouth to refute, Du Xiang, the minister of the Ministry of War, also stood up and warned about the negative consequences that would be caused in the future if the Mengshe imperial edict merged with the other five imperial edicts. The scene described in Lao Du's words was almost exactly the same as the content of the secret letter he wrote to Zhou Ziliang on Tuesday! As soon as Du Xixi finished speaking, the current prime minister Niu Xianke, who was an old Jiedu envoy, also stood up and expressed his support for the opinions of the previous elders. Chen Xilie, the third-ranked prime minister, has always respected Zhang Jiuling. When he saw that Lao Zhang spoke out and seemed to make sense, he also clearly supported Lao Zhang's opinions. At this point, Li Longji¡¯s thoughts have actually been greatly shaken. But what the emperor didn't expect was that many ministers later also spoke out against it. Their opinions were basically unanimous, that is, the military faction should be the one, but the six imperial edicts could not be merged and unified! Seeing that everyone had finished talking, the Censor Zhongcheng Zhou Ziliang, who had been silent until now, calmly took a step forward and said loudly: "My lord, the Censor Zhongcheng Zhou Ziliang has written a note!"
