“You want me to go on an impossible journey, sacrifice everything, and risk my own life for a mere 1,000 gold? Hell no!”Lukas never really had anything going in his previous life. When he found himself transmigrated into a new world, he had hoped the soft and gentle touch of a hot milf would mark the beginning of a lavish lifestyle befitting a king.Instead, he quickly learned that he was just some random extra. Worse than that, this extra was only known by everyone as the “Divine Simp,” someone who would do whatever the gods asked.“Divine Simp? Fuck that!”Refusing such a pitiful existence, Lukas decides to take this new life in his own hands. Instead of waiting for some lavish life to fall in his lap, he would create one for himself.How?Well, the gods seem to love him. They shower him with quests, thinking that he will just take them for free. Little do they know... that old extra is dead and gone now.The Divine Simp has become the Divine Extortionist: someone who can obtain the greatest rewards for completing the easiest tasks.

It was a life without regret. My parents were in good health, and I wasn’t homey enough for me to combine my studies and part-time jobs.
