HUIDAO DIQIU DANG SHEN GUN

He had been missing for eight years. But no one realized that he had traveled to another world and cultivated for eight thousand years! After returning to earth, he looked for his sister, but no one thought that he would overturn all the major forces on the earth at the same time! He kidnapped the rich girl, but nobody would've expected that he'd wipe out her fiancee, too. He can fight hand-to-hand or brew up potions. Anyone who messes with him... will be doomed to eternal damnation! (Source: Tencent, translated) — Description from AniList community (anilist.co).
