Immortal Dark Lord

A powerful man of the Imperial Realm was killed by his true love and close friends, but he was reborn in a lost world with hatred because of his secret technique "Seal, Heavy, Forbidden". There are thousands of clans in the world, there are many sects, and there are strong men like clouds. Look at him, one man and one sword, cutting through the world, destroying the shackles of the world, controlling life and death, controlling yin and yang... Once again, he embarks on the road of being strong!
