DNF: I Have an All-Purpose System

Lin Yi successfully amplified his Taiji Heaven and Earth Sword to +17. Overcome with excitement, he suddenly died and returned to the early days of the Level 60 era, where he obtained the DNF All-Purpose System. Lin Yi: Now that I’m back, how could I not stock up on White Tiger Souls? Xu Xu Baby: Brother Yi, about this Ancient Relic Katana of mine... Big-Spender Bro: Brother Yi, I accidentally transferred 100,000 yuan to your account. Could you give me a +15 National Mourning Sword in return?
