Being Targeted by the Seven Sins, I Started to Counterattack and Kill the Gods.

[Campus Superpower + Contract Summoning + Tsundere Sword Girl + Suspense Strategy] Mo Yi, an ordinary high school student, was involved in a strange "holy war" - in seven dark palaces, beings called "sins" controlled Servants to start a bloody game. 36 Masters must fight until only seven are left, and the winner will ascend to the "God's Throne". When classmate Chu Chen awakens to protect Servant Jiawen, and the school belle Ye Jin reveals her mysterious trump card, Mo Yi is shocked to realize that he is actually a pawn selected by "Rage", and his body contains the power to summon the strongest Saber "Holy Judge Cong Yu". On one side is the venomous tongue and blade of the arrogant Servant Cong Yu, and on the other side is the complicated calculation laid out by Ye Jin. Mo Yi struggles between the classroom and the battlefield, but finds that his sister Mo Ran seems to be hiding a deeper secret. When the campus is reduced to a chessboard, there are runes hidden under the desks, and there may be murderous intent hidden in the smiles of his classmates. He must hold on to the "fury" in his hands amidst the holy light and hidden arrows. Either become a chess piece and be crushed, or burn everything and let the Seven Sins see - mortal obsession can also kill gods. (It should be stated in advance that this novel refers to the setting of Fate, so there will be many similarities such as Master, Servant, etc., But please do not directly regard it as a fanfic of Fate. The author has made some modifications, such as: there are no longer seven Masters, expanded to 36, Servants know each other, the functions of Noble Phantasms and Command Spells are modified, the rune circuit is changed, etc., So if you don't like it, you can quit directly and save your life)
