Li Changzhou left in a hurry, but his pace was slow, moving too fast might mean not encountering those three, and he also needed time to think.
"Tang Seng's body might not stay hidden for two days," Guanyin reminded him, as it wasn't yet time to declare everything safe.
Carrying Tang Seng's body was not an option, nor was it feasible.
Even Sun Wukong, who had consumed the flesh that grants eternal youth, could not manage it, so how could he?
Moreover, since Tang Seng was key to the journey of scriptures, if Li Changzhou took the body, countless immortals would immediately appear to aid Sun Wukong.
And if he didn't, like now, hiding the body in the Tongtian River, those immortals would treat it as a test for Tang Seng and his disciples.
Li Changzhou had to strike the right balance, too little and he wouldn't be able to capture Tang Seng, too much and he'd be besieged by legions of heavenly gods and Buddha.
