Cursed Back, I Actually Summoned the Demon Azazel

He was reborn as Chanyuan Shi'er's younger brother, but under the spell, he only had a summoning system! What? Summon one hundred million at a time! Demon Azazel? ! What kind of devil is this! What do I need from you! Anyone can be slapped away! Jiujiu pill! Short and weak? Holy Sword Esther! Boss! Hey~ Can I still survive until the finale? Newbie, new book, I hope you can forgive me for the bad writing! Kneel down and thank you~
