The Master of the Heavenly Net, that is Xu Fu, mentioned only a snippet of his own past and was particularly secretive about how he betrayed the Immortal Sect, as if he didn't want Li Chen to know.
Li Chen could understand this.
Although he was extremely curious about Xu Fu and Caesar, these two ancient beings who had lived for two thousand years, he did not have the habit of prying into other people's privacy.
Moreover, his current relationship with Xu Fu was merely a temporary alliance—both friend and foe, incredibly delicate.
Therefore, when it came to Xu Fu's words, Li Chen had to deliberate carefully before choosing what to believe selectively. He couldn't just take everything at face value.
Otherwise, he wouldn't even know how he died when the time comes.
