Naruto: Get Saitama's Training Method at the Beginning!

Lin Bei traveled to the world of Naruto to obtain Saitama's training method! As long as you persist for three years, you will gain Saitama's 100% strength! From then on, I punched Madara Rokudo and kicked Otsutsuki! When you encounter a nasty ninja, punch him to death! "Lin Bei, when can I pay back my ramen money!" "Sorry Naruto, all the money I earned was used to pay off the mortgage." Three years later, Naruto returned from his studies. "I have found out clearly that your mortgage has been paid off!" "I'll save the money to pay you back." Payne invaded and the entire Konoha Village was destroyed. Lin Bei went crazy watching the house where he had just paid off his mortgage be destroyed. "I want the world to feel pain!"
