My Sword Can Kill Immortals

Lin An was betrayed by his childhood sweetheart, but unexpectedly opened up the greatest opportunity of his life. He got the "ink" left by the founder of the Supreme Sword Immortal. He progressed all the way, grew up, took revenge, and found the person he wanted to protect, the heroine Yun Ningshuang. She gave Lin An a lot of help on his spiritual path. He bid farewell to the heroine, embarked on the road to immortality, became a sword fairy, and returned to save the heroine's domineering power. After founding the Yun'an Sect, Lin An continued to embark on the road of near-death, while the heroine was here waiting for his return. Lin An created the pinnacle of the world of sword cultivation and became the "Zhu Xian" above the supreme sword immortal. When he returned again, he saw that the world had been greatly reshuffled. He led the heroine to stand up again and established the world's largest sword sect, the "Zhu Xian Sword Sect". The two got married, cleared all obstacles to his wife's practice, and sent his wife to the sword immortal.
