Wei Zi, the Great Emperor of the underworld.

Emperor Taizong, who promised the old dragon king to save his life, failed to keep his promise, which will inevitably lead to harassment. Thanks to the protection of Uncle Bao and Jingde (the origin of the door god), Emperor Taizong was not awakened by a nightmare, but his health deteriorated and he died in the thirteenth year of Zhenguan.

The next story is that after Emperor Taizong entered the underworld, Yan Jun of the Tenth Hall explained the whole story to him. Knowing that Emperor Taizong still had 20 years to celebrate his birthday, he was sent back to the dead.

There is an extremely strange phenomenon here, that is, why Emperor Taizong was able to come back to life in hell, but other emperors were not spared. This is obviously not because of the unique aura of Emperor Taizong, nor because he is an emperor himself. Many people read the words "We are the king of the underworld, and your majesty is the king of the dead" in the original text, and think that Taizong and Yanjun are naturally equal.

Actually, it is not. When we read China's ancient novels with mythical colors or elements, we finally found clues: many heroes in Tang Shuo have gods, such as Li Yuanba reincarnated as a golden-winged Dapeng bird, Yuwen Chengdou reincarnated as a nine-day fairy, and Li Shimin reincarnated as the emperor China at the zenith and north pole.
