Returning to Earth, I Am the Only Cultivator

[Urban cultivation + invincibility + decisive killing + multiple worlds + cool writing] Ten years ago, Wu Fan disappeared mysteriously, fell into another world and practiced hard for 100,000 years before becoming the Supreme Immortal Emperor. In order to relieve his obsession, he spent all his cultivation to tear apart the immortal barrier and forcibly returned to the earth. Both his mana and body fell to the first level of the foundation. However, what greeted him was the tragic situation of his parents dying, his only sister being forced into a desperate situation, the girl he liked being forced to get married, and his good friend being persecuted by a bad hospital, and his family was ruined. Seeing his home falling apart, the former Immortal Emperor made a blood oath: He would reach the top again and reverse the cycle of time and space! Resurrection of parents, so that loved ones will no longer be bullied at all!
