Hi guys, I have read this one novel where the MC is reincarnated into ancient time. Due to her reincarnation, she’s become immortal and have strong body. She meet an old general who will make her his student and transfer his qi into her. She’s talented in sword.. She fought in army as general to unite the country to bring peace to the world (fulfilling her master’s wish). Later she died and resurrected and become wanderer and collect many book. She’s kinda become a legendary wanderer that give someone his fortuitous encounter.
