Modern people accidentally traveled through time and came to the world of the novel of the same name, "Buddha's Prosperity and Taoism Decline", and became a helpless little Taoist priest.
This world is a Dharma-ending world. The ancient divine war destroyed most of the earth veins. Only the last dragon vein was suppressed by the Great Wall. The Great Wall also sealed the ancient killing saint Chi You.
On the surface of the world, Buddhism is prosperous, Taoism is in decline, all people worship the Buddha, and Taoist priests are looked down upon and ostracized. Buddhist practice mainly focuses on chanting sutras, forcibly cutting off the seven emotions and six desires, and the skills are incomplete. There are only three quasi-sages, Deng Deng, Tathagata, and Maitreya, on the top floor, and they cannot become saints.
On the other hand, the Taoist sect has a complete inheritance and specializes in quiet mind methods, inner elixirs, and thunder methods, and can directly reach the realm of saints through dual cultivation of life and life. The Taoist sect is dormant in the world, with twelve quasi-sage Taoist priests guarding it, and three saints from the Sanqing Dynasty sitting in charge. The current orthodox heavenly master is Zhang Enpu, the 63rd generation heavenly master, who sticks to Longhu Mountain and secretly maintains the fire of the Taoist sect.
And deep within the protagonist's body lies the origin of Chi You's eternal soul. As the dragon's veins loosen and the seal continues to weaken, Chi You's murderous rage continues to erode the protagonist's Taoist heart, making him an inner demon that he cannot get rid of throughout his life.
The protagonist devotes himself to practicing the orthodox Taoism and adheres to the Taoist mind of peace and inaction. While struggling to maintain the Tao in a world where Buddhism is prosperous and Taoism is declining, he fights against the murderous thoughts of Chi You in his body, and at the same time avoids the pursuit and suppression of Buddhism.
When the seal was completely broken, Chi You woke up completely and transformed into the final BOSS of the book. Holding the Blood Glazed God-Slaying Sword and the Soul-Slaying Axe, he wanted to reshape the order of the world with his killing method. In the end, the Three Pure Ones, the Twelve Quasi-Sages of the Taoist Sect, and the Third Buddha of the Buddhist Sect joined forces to fight against Chi You. The protagonist was also in the ultimate struggle between his own Taoist heart and the demon's murderous thoughts.
