The auspicious clouds of the Buddhist Kingdom over Chang'an are stained with ink, the pages of Mahayana scriptures in the Tibetan Scripture Pavilion are stolen one after another, and the appearance of the remains of monks and the soul-eating scales of demons outside the city reveals a corner of the three-hundred-year westbound scam. Xuanzang's fingertips touched the coldness of the broken scriptures, and the Taoist token on his chest suddenly became hot - it turned out that the scriptures he obtained in his previous life were not to seek the Dharma, but to join forces with Buddhism and Taoism to suppress the conspiracy of the great sage of the demon clan. Now that the seal is loose, the catastrophe of the Three Realms is coming.
When he set foot on the westward journey again, his target changed from the true scriptures to the relics of the ninth generation scattered along the way. In the Five Elements Mountain, he combined the power of Buddha's light and Xuanmen to survive the fire and flood trials, confront the demon guardians in front of the altar, and find life between grudges and righteousness; at the bottom of the quicksand river, the green-faced and fanged Sha Wujing faced each other with a shovel. The resentment of the former curtain-rolling general was not gone, but the surprise attack of the black-scaled python forced him to join forces with Xuanzang to fight against the enemy.
Along the way, Kasyapa in the Buddhist world has hidden murderous intentions, and the old members of the heaven have their own evil intentions. Sun Wukong, who has awakened his demonic nature, points his stick at Lingshan Mountain, and the candle dragon and the resentful spirit of Guixu in the "Shan Hai Jing" appear one after another. Xuanzang is no longer a pedantic monk. He understands the true meaning of the inner alchemy of "refining gods and returning them to the void" in the secret realm. He eliminates his own obsession in the battle of mirror images. He also needs to piece together the truth about the ancient war between gods and demons and the seal of demons in the cracks of the power game between Buddhism and Taoism.
When the light of the ninth-generation relics illuminated the back of Lingshan Mountain, Xuanzang finally understood: The so-called Xuanmen Tribulation is not only a crisis of collapse of the order of the three realms, but also a trial of Taoism for every practitioner to break through his destiny. Not all Buddhas are good, and not all monsters are evil. The Zen staff and token in his hand will eventually open up a new path to reshape the world through resistance and perseverance.
