Li Fan, a modern social animal, died suddenly after staying up late to change his plan. When he opened his eyes, he was transformed into a Tang monk who had just left Chang'an. Others seek sutras to save sentient beings, but all he thinks about is "making money" - the brocade cassock given by Emperor Taizong of the Tang Dynasty. He first feels the material to estimate the market value; when encountering monsters, he does not panic and chants sutras, but first takes out his mobile phone and wants to "call the police". If it doesn't work, he uses "boss-style squeezing thoughts" to collapse the bandit's thoughts.
Recruiting an apprentice also brought about a sudden change in style: he tricked Sun Wukong into wearing a tight hoop, saying it was a "smart heart rate bracelet"; he thought Zhu Wuneng's name was unflattering, so he forcibly changed his name to "Zhu Peiqi" and made him a "foodie internet celebrity" selling steamed buns; Sha Seng had "worker attributes" and was praised by him as "more reliable than his former assistant".
On the way to learn the scriptures, he didn't care where the scriptures were, he only cared about "whether there were enough funds," "whether he could stay in a B&B," and "whether the jewelry in the monster cave could be used as funds." When he passed by the Kingdom of Women, he first marveled at the queen's beauty, and then calculated "how many boxes can be packed with this 'breakup fee'"; it was difficult to tell the real and fake Monkey King, so he easily solved the case by asking "did he eat yesterday?"
When a reliable apprentice meets Tang Seng, who is "rotten + real", he travels thousands of miles and turns into a ridiculous adventure full of modern jokes, complaints and jokes - but Li Fan never understands: Why do I just want to cash in my cassock, but I am always chased by monsters asking for "Tang Monk's meat takeout"?
