MTL - Super Invincible Battleship - Chapter 178 Cause and effect

The protagonist fell asleep while playing an online game. However, he awoke in a strange world with his game character’s appearance. In a state of shock, he noticed that he was equipped with nothing but his strongest weapon and armor. To make matters worse, our hero’s appearance was changed by the special avatar skin『Skeleton』when he entered this new world. The protagonist wanted to live without drawing attention, but he got acquainted with the dark elf Ariana and received her request.

She became the young mistress of the most powerful family in City T by marrying the young master in place of her sister.

He was cold to her on their first nuptial night. "Just because you played some tricks to get yourself married here, you still mean nothing to me!"

However, she was calm and heartless. "Young Master Mu, don't think too highly of yourself. I despise all that is you — your money and your very being!"

After the wedding, Young Master Mu lived lavishly by spending money like flowing during the day while working his nights away busily. "You said you despised me earlier. Well, which part of me do you despise exactly, hmm?"

Luo Chenxi could not bear the harassment any longer so she tossed out the divorce papers in rage. "I can't live like this much longer..."

Survival is easy. Life is very difficult. My family wants not to live in humility, but to live a proud and glorious life. My family, will not be slaves!
