Naruto: All My Disciples Are S-Level

"Obito, after you finish this set of questions, I will teach you S-level ninjutsu!" "Kai, after running these 100 laps, I will teach you peerless physical skills!" "Shisui, as long as you obey, Uchiha's future is in your hands!" After traveling through time and becoming a chunin in Konoha, Ye Bufan had to transform into a "cake master" in order to get rid of his root control. As long as you draw a cake for the students and let them practice hard, the system will crit and return rewards to the host! Thus, the most popular class in Ninja School was born. In order to learn ninjutsu, Obito stayed up all night memorizing theoretical textbooks; In order to learn physical skills, Kai ran out of the playground into a ravine; In order to gain the teacher's approval, Shisui practiced the seals day and night. Seeing the students exhausted, Ye Bufan drank tea and counted the system rewards. Bite! Obito passed the theory, and the host gained mastery of fire escape! [Ding! Kai Taishu breaks through, and the host obtains the Eight Gate Dunjia! Colleague: "Teacher Ye, you are working too hard. You are driving the students crazy." Ye Bufan spoke righteously: "This is all for their own good! I am a strict teacher who produces outstanding disciples!" Only he knows that if he doesn't work hard to become stronger, Danzo's sword will be placed on his neck!
