Summoning demons—I am the AbyssDevil Summoner, I am the Abyss Lord; Devil Summoner, I Am the Abyss Lord; Invocando Demônios, eu sou o abismo; 召喚惡魔,我既是深淵

Lin Tianhao, who has transmigrated to another world, attends the Job Change Ceremony and ends up taking on a sewer-tier job Summoner. Just as everyone is mocking him, believing his future is doomed, he suddenly awakens a system and gains the skill [Demonic Sacrifice]! Who says the Summoner class is trash? I have the strongest SSS-rank talent!
