I'm in Naruto, but There's Actually a Sun in My Body

Lin Nianjun, a sophomore student One day, when he was looking out from the balcony, he was hit by a ball of golden light flying from the sky and fell into a coma instantly. When he woke up, he found that he had arrived in the world of Naruto. But what shocked him even more was that he could actually look inside his own body, and through his body he could clearly see a sun floating in his abdomen. A sun with a diameter of nearly 1.4 Million kilometers, a surface temperature of 6,000 degrees, and a core temperature of 15 million degrees. … Five years later Lin Nianjun faced the two brothers Jin Jiao and Yin Jiao, "Please remember my name. My name is Lin Nianjun. Next, I will beat you two to death, or I will be beaten to death by you two!" … Konoha Hospital, in front of Senju Tobirama's bed Lin Nianjun looked at the angry expressions of Mito Menyan and others without paying attention. "Never be angry, never threaten, be reasonable. With the form of a tiger, with the voice of a rose." "And my truth is only above my fist!" … Shortly after the end of World War II Hatake Somao suffered public opinion and rejection due to the failure of his mission, and Lin Nianjun stood up again. He strangled Danzo Shimura's neck tightly and looked down at Sarutobi Hiruzen. "It seems that the years of Hokage career and power have completely eroded your eyes, so that you can't see the essence of this world clearly." "Then let me tell you." "The nature of this world is that the weak eat the strong, and the strong are respected." "My fist is bigger than yours, so if I say he is, it means he is not!" "After I finish speaking, who is in favor and who is against?"
