Lin Fan's answer to the black ball of light's question was also the answer to his own questions.
The only way to discover the real answers to his questions was to move forward. Without moving forward, he wouldn't be able to find any clues as to what this world was or what his goal in this world was.
Since that was the case, he would follow the path that this world had placed in front of him. He would work with the black ball of light until he was able to take revenge for the identity that he had been given.
Of course, it would be a lie if it was said that there weren't a bit of personal emotions that were involved in this revenge.
After all, he had spent close to two years with those people, if it was said that he didn't develop any feelings for them at all, that would have been a lie. Deep down, he did want a bit of personal revenge.
The black ball of light was completely silent when it heard Lin Fan's answer.
