Son Goku was destined to take Patriarch Subhuti as his master. That could not be changed, nor did Li have the ability to change it. With Li's strength, he was utterly insignificant before the Buddhist sect. Perhaps in the distant future, Li might be able to influence the fate of the Buddhist sect, but for now, any random arhat could decide whether he lived or died. He had just killed three novice monks, and the Buddhist sect would soon learn of it. With Tathagata and the others' abilities, finding out would be effortless.
If those three novice monks had decent origins and were highly valued within the Buddhist sect, perhaps even a bodhisattva would personally make a move. Even if they were merely three ordinary novices, their master—the arhat mentioned by that novice earlier—would still act. An arhat was at least a True Immortal-level expert, two entire major realms above Li. No matter how extraordinary the Nine Revolutions Mystic Art was, it could not allow him to kill an enemy two realms above him at this stage. More importantly, Li lacked any decent magical treasures, which was another major weakness. As an arhat of the Buddhist sect, his status was fairly respectable. At the very least, he should possess an acquired spiritual treasure, and an acquired spiritual treasure was countless times stronger than an acquired magical artifact.
Therefore, no matter what, Li could not continue traveling with Son Goku. Only those in the Buddhist sect, the Daoist sect, and the Celestial Court who held real authority knew that Son Goku was the scripture seeker. Small fry like arhats naturally had no right to know. When they came hunting him down, Son Goku might be implicated. Besides, even if they did not pursue them, Li could not accompany Son Goku to
