Shock! I Actually Took the Graduation Exam at the Same Time as Zabuza

My name is Qian Yu. I woke up and traveled to the world of Naruto and became an intern ninja in Kirigakure Village. I was about to take the graduation exam, but I found that the demon Zabuza who single-handedly killed all the students in the current year in the original book was at the same time as me. Shock! The beginning is hell difficulty! Please tell me what I can do to survive in the hands of Kijin Zabuza? Waiting online, it's very urgent! ! This novel and its characters are purely fictitious.
