"That's a good question."
Elder Qian nodded frankly, without a hint of concealment, "Because we old folks are rather afraid of death."
Seeing the astonishment on Cheng Ye's face, he gently shook his head and explained, "The biggest difference between Immortal Objects and ordinary infection sources is the degree and direction of their influence by the S3 and S4 viruses. The infection sources you are encountering now can only be considered 'ordinary versions,' their predecessors were not truly Extraordinary objects, merely partially mutated by the S3 virus. People of the old era called them 'treasures': they could bring some benefits but couldn't help people become Extraordinary."
"Only those 'Extraordinary objects' that existed during the S3 period and were never discovered or used by humans, when mutated by the S4 virus, they can be called 'Mother Sources.' The mutation direction of these Mother Sources is primarily in pursuit of 'ultimate evolution.'
