The Son-In-Law Who Came to Visit Was Actually the Mysterious Island Owner

He is the third and most inconspicuous of the nine sons of the Chen family. He has been roaming the mountains and fields since he was a child, herding cattle at the age of ten. He became a son-in-law at the age of twenty, and was treated coldly and harshly. I have spent half my life in the mud, experienced the warmth and coldness of human relationships, and once doubted life while struggling at the bottom. No one knows that this useless son-in-law who can be bullied by everyone is actually the only heir to the ancient island inheritance, the mysterious island owner who controls hundreds of millions of forces, the co-lord of the four seas who controls thousands of waters, and the hidden supreme being who sleeps in the mortal world! Once the sharp edge is revealed, all those who bullied him and humiliated him in the past will bow their heads and tremble; all the disobedient people from all over the world will be crushed and surrendered! The son-in-law returned to his throne, turned over the sea, took charge of the world, and became powerful in the world!
