Lin Xuan, a mortal, was accidentally bound to a strange 'Tiandao System', using a humorous way to break the boring path of cultivating immortality. He entered the world of cultivation as a "waste", and was tortured by various "system tasks" to the point of laughing and laughing, but he repeatedly met noble people - the cold-faced swordsman Su Mubai, the unreliable fat disciple Sun Qi, the naive spiritual beast Da Zhuang and other partners. Intertwined with layers of crises and adventures, Lin Xuan continued to grow, reversed his fate in the "farce", and defeated the "Taoist Chen Xian" who seemed to be unruly but actually controlled the chess game of all living beings. The book is ups and downs and compact, both light-hearted, humorous and full of emotions; the three volumes are interlocking, and at the end, Lin Xuan leads his friends to face the world with a smile and walk out on their own happy and miraculous path.
