In Ye Qingfeng's eyes, waste spirit stones were still very precious, but in comparison, Tian Shi's security seemed virtually nonexistent.
Without a single security guard, it would be easy for someone to steal them.
Tian Shi shook his head and smiled bitterly, "I used to treat these Energy Stones like treasures and protected them very strictly. But after over a decade of research without any results and no more research funding, I left them here. Over the years, not a single thief has appeared."
Ye Qingfeng immediately understood that the waste spirit stones contained a lot of energy impurities and were very difficult to extract.
