A Top Student in the History Department, He Got the Assassin Sequence at the Beginning

[I just want to write my thesis in peace, why are you forcing me to kill someone? Lin Xun, a top student in the history department, accidentally inherited the spiritual power of Yu Rang, the first assassin of the Warring States Period, through a ridiculous "Ancient Ceremony". From then on, his college life completely went off track—— Jixia Academy Trading Hall: "The master of the country solves his doubts online! The inside story of the Battle of Changping, the source of Bai Qi's murderous thoughts, and the truth about Cao Cao's murder in his dream, everything you need!" "The price is fair, I'm honest, and if you don't have enough credits, you can issue an IOU!" Qin School stronghold: Su Qin's successor Zhao Wenhe: "How dare a wild assassin be so arrogant? Surround him and kill him!" An abandoned factory: Lin Xun slit the enemy's throat with a knife and clapped his hands calmly: "I'm sorry, Yu Rang's knife never knows what it means to be merciful." All forces: "..." This nerdy style is wrong! What about the intellectuals you promised? --- Three months later—— The elder of a certain domineering school said: "Boy, hand over your secret assassin skills and I will spare your life!" Lin Xun sealed his throat with a knife: "I'm sorry, Yu Rang never leaves anyone alive." Half a year later—— Strong men from all walks of life surrounded you: "No matter how high your martial arts skills are, you can't beat four hands with two fists!" Lin Xun's figure is like a ghost, coming and going freely among thousands of troops: "Have you ever heard of 'A soldier dies for a confidant'? Today I will let you see what the true way of an assassin is!" One year later—— The world was shaken, and the name of the national scholar spread throughout the nine states!
