Despite the cold spring, despite the warm and cold, the spring of the first year of Yuan and the first year still arrived as scheduled. The bone-chilling wind turned into a willow wind, and the cold rain turned into a rain of apricot blossoms. "The light rain in Tianjie is as moist as a crisp, and the grass color is close but there is nothing", on the outskirts of Chang'an, looking at it from a distance, it is a piece of green. Green represents spring, spring represents hope, in this vibrant season, Li Chun, who has just ascended to the throne, is also full of hope and vision for a better future: Wang Ling is dead, Wang Shuwen is dead, Shu Wang Li Yi is dead, and the emperor Li Yu is also dead, the throne has been relieved, and the next step is naturally to deal with those unruly feudal towns.

"I want the feudal towns to truly submit to the Tang Empire, and I want the envoys to restore the old practice of visiting Chang'an," Li Chun secretly vowed. According to the ancestral precedent, every few years, the envoys of Jiedu would return to Chang'an and personally report to the emperor or prime minister about the local customs and political affairs. Even those who are as arrogant as An Lushan have been to Beijing many times, and in the cold winter, they sweated profusely to accept the questioning of Prime Minister Li Linfu. But once upon a time, everything that was beautiful was a thing of the past, and the envoys had already fallen in love with the feeling of not returning to Chang'an, and let the former prosperous and lively imperial capital spend a cold time year after year. Tracing back to the ancestors, the culprit is, of course, the hateful Wei Bojie envoy, the treacherous and cunning Tian Chenghei.

Tian Chenghe's grandfather and father have chivalrous names, and he himself was famous for being heroic when he was young, and the best way out for this kind of person is, of course, to join the army, so Tian Chengsi later joined the army, and soon became a general under An Lushan. But Tian Chengsi's real vision of An Lushan stemmed from an accident, and it seems to be inevitable. It was a cold winter with heavy snow, An Lushan walked through the snow to inspect the barracks, and found that Tian Chenghe's camp was silent, if there was no one, An Lushan was of course very angry, and decided to find out those soldiers who deserted and punish them severely. So, he opened the list of soldiers and began to roll call, but was surprised to find that there were not many soldiers. After this incident, Tian Chenghe's prestige was greatly enhanced, and the strictness of his army management can also be seen.

After An Lushan's rebellion, Tian Chengsi led the iron cavalry to sweep up and down the river, and it was unstoppable. After An Lushan's death, Tian Chengsi was disheartened and led his army to surrender to the imperial court. But when Shi Siming made a comeback, Tian Chengsi raised the banner of rebellion again, which made the government army suffer a lot. But when Shi Siming also died at the hands of his son Shi Chaoyi, Tian Chengsi finally understood that the rebels were gone and began to plan to get out. He took the initiative to lead the army to join Shi Chaoyi's remnants of the defeated army and trapped Mozhou. The Tang army flocked to it, Shi Chaoyi was at a loss, but Tian Chengsi was already ready. He agitated like a reed and persuaded Shi Chaoyi to break through in the middle of the night and return to his old nest Fanyang, in order to make a comeback, but left his family in Mozhou. Tian Chengsi's tearful performance moved Shi Chaoyi inexplicably, and he fell into the trap arranged for him by Tian Chengsi without hesitation. Flickered away the old boss Shi Chaoyi, Tian Chengsi changed hands and gave his family to the Tang Army, in exchange for a set of great wealth, the former rebel army will be transformed into the Wei Bo Festival envoy of the Tang Dynasty, not only sitting on 100,000 elite soldiers, occupying the rich side of the Wei Bo five states, but also has the most fierce private arm, "father and son hereditary, marriage party intertwined" Wei Boya army. But Tian Chengsi belongs to the kind of people who have an insatiable desire, his greedy eyes are staring at the adjacent Zhaoyi, Zhaoyi Jiedu made Xue Song die, he sent troops to attack Zhaoyi's Xiangwei Sizhou, Li Chun's great-grandfather Tang Dynasty Zong couldn't bear it, and finally issued an edict to crusade against Wei Bo.

"Black clouds crush the city and want to destroy", Youzhou Jiedu made Zhu Tao, Chengde Jiedu made Li Baochen, Hedong Jiedu made Xue Jianxun, Ziqing Jiedu made Li Zhengji and Huaixi Jiedu made Li Zhongchen and other armies attacked from the north and south, Wei Bo was in danger, and his generals defected one after another. But the treacherous and cunning Tian Chengsi tried his best to move around, skillfully dialing thousands of pounds in four or two, and resolving the crises invisibly.

First of all, he pretended to make a gesture and wrote to Chang'an, asking to be attached to the imperial court and give up the hegemony of Hebei that he had operated for many years. Faced with such temptation, Chang'an hesitated, and the old fox Tian Chengji made full use of this precious time difference and began to set out to break up the army besieging him. He sent a messenger to hand over the domestic household registration, armor soldiers, grain silk, etc. to Li Zhengji, and also flatteringly said that he was old and decrepit, and his children and nephews were also very unsuccessful, and everything he had today was just for Li Zhengji's temporary care. Tian Chengji even brazenly hung Li Zhengji's portrait in the hall and burned incense to worship in the morning and evening. Li Zhengji was tempted, bang, so he decided to stand still. If Li Zhengji did not move, the soldiers of Henan Zhudao did not dare to attack rashly, and the threat of the army on the southern route disappeared in this way.

After relieving the danger of the south, Tian Chengsi began to concentrate on dealing with the northern officials and troops, but the magic weapon was still divided and disintegrated. This time, a little sowing discord was added. He learned that Li Baochen's hometown was in Fanyang, and often wanted to take it as his own, so he made a plan by carving stones, and expressed his willingness to give up Cangzhou to Li Baochen, and help him plot Fanyang and Chen Bing. Li Baochen then sent troops to attack Zhu Tao, and the two sides fought against each other. In this way, the army on the northern flank besieging Tian Chengji was also disintegrated.

A year has passed, and the battle has not been fought yet, and the armies of the north and south have long collapsed. Tian Chengsi wrote to Chang'an again in due course, saying that he wanted to enter the court to apologize. After nearly a year of expedition, Chang'an was exhausted, so he got off the donkey and issued an edict to pardon Tian Chenghei. But Tian Chengsi obviously didn't want to save face for Chang'an, and after the expeditionary army retreated, he not only forgot about the Hajj, but also provoked another war just a few months later, this time, he stretched out his hand to Bianzhou and Songzhou. Chang'an, who couldn't bear it, gathered heavy troops again, and Tian Chengsi "obediently" sent a letter of plea, and Chang'an, who was played by Tian Chengsi between the applause, could no longer withstand the toss, and issued an edict to grant Tian Chengsi permission to avoid the audience.

The power of example is endless, with Tian Chenghei as an example, all parts of the festival envoys have followed suit. Since then, Chang'an has lost the dignity and prestige that the imperial capital should have, and has become the object of ridicule and ridicule in various feudal towns.
