I'm Really Not the Lord of Monsters!

After a period of arduous life in a different world starting from scratch, Shen Yuan left the sealed land full of monsters and entered the peaceful and beautiful human world. The human world is safe and harmonious, and its mental state is very beautiful. Occasionally, monsters fall here from the sealed land, and they will be quickly solved by the Hunter Association. Shen Yuan was very satisfied and opened a pet shop to start his own retirement life. In the first month, there were constant messages on my phone every day. [My Lord, everything is fine in the sealed land today, and the wastes seeking death have filled the rose field in front of your palace. My Lord, when will you return? Oh, my master! Without seeing you for a day, I can hardly suppress my desire for blood and pain! Master, when will you return? [Boss, all those human players have disappeared, so boring! So boring, so boring, so boring! Boss, when will you return? But Shen Yuan bought a new phone card, and his phone couldn't have dual-SIM dual standby, so he didn't see any of those messages. The second month, the third month... The bombardment stopped. However, the Hunter Association issued seven most wanted warrants, claiming that the infamous "Seven Disciples" had entered the human world and that the rumored Lord of Monsters was about to arrive, bringing endless darkness and terror to the world. - "Many years ago, the entire human world fell into a horror game where you would die if you did not clear the level. In that game, there were endless monsters. The seven monsters at the top of the sequence were called the "Seven Disciples", and the master they served together..." "His gaze can confuse the mind, his voice can annihilate the soul, and his existence is terror itself." "——He is the Lord of Monsters." Sitting in the pet shop, listening to the hunter association's safety propaganda, Shen Yuan nodded frequently, caressed the head of the Sequence Three dog under his palm, took the milk tea from Sequence Two, and looked at the pet area through the window. There, Sequence One is taking a nap. In the human world, sequences four to seven are causing a bloody storm. - On this day, Shen Yuan finally remembered his other mobile phone number. He clicked on the message at the top of his mailbox. [My Lord, why haven't you come back yet? Are you planning to conquer this world? [We will uphold your will and conquer the human world—dedicate it to you intact! Shen Yuan: "..." No thanks, he doesn't want it. What monster lord? Don't get involved! Retirement life and conquering the world are not suitable at all. He really doesn't want to rule the world anymore! Purpose: Peace-loving
