It's just that he walked off the altar in this play, and he is no longer the Di Renjie who has always been called the God Man. He will make mistakes, fall into traps and get tired. He will immediately give up the rare opportunity of exploration because of Li Yuanfang's injury, and he also needs the assistance of others (especially Li Yuanfang) to complete the investigation process. This kind of performance will make people feel more real and grounded. After all, De Renjie is a real historical figure, not a god.
Besides, Li Yuanfang has changed people. He is many years younger than ZhangZijian, and his acting skills are OK. He and Di Pangpang also have a tacit understanding, but they are less popular and less domineering. Li Yuanfang in the play was also asked to leave the altar. Even if he is skilled in martial arts and resourceful, he will be injured when he meets an equal opponent, and even an adult will be injured because of a moment's negligence.
