I Really Am Not the Lackey of the Lord God!

Legend has it that every seven days, the world will come to an end, and at that time, the door to hell will open. Countless demons crossed the gate and entered the human world. They call themselves 'Dream Walkers'. Lin Xuefeng traveled from the earth, signed a contract with the evil god, and obtained the ability of equal exchange. "Eyeball Holy Relic + Illusion Elements = Blood Wheel Eye" "Sacred Stone + Lava Elements = Lava Beast Malphite" "Biological egg + super element = Pokémon Mewtwo" ..... When Lin Xuefeng unearthed special equivalent exchange formulas, his painting style became increasingly strange. "Let me tell you first, I am really not a lackey of the Lord God. I am just an 'ordinary person' who likes exchanges of equal value." "Believe it or not, beat this foreigner to death!" The story all starts with a special train ticket.
