After the Adopted Son of the Country Accidentally Entered the Demon Slayer Manga

Shirakawa Nagisa has two fathers. The eldest father follows Guo Yansheng, who has six eyes, and is said to have a name called Hei Shimo; the second father follows Guo Yuanyi, has two eyes, and is said to have a codename called Rizhu. And he, Nagisa Shirakawa, was the adopted son and apprentice of the country. After the death of the Ghost King, he was adopted by his two living fathers. As a candidate to inherit the breathing method, the sun call in his left hand has high damage, and the moon call in his right hand has high damage. He can lift tiles from the top and chop down ghosts from the bottom... No, there are no ghosts in his world anymore. But in order to exercise his body and complete the training tasks of living dads, Shirakawa Nagisa must run fifty kilometers at night every day, swing a knife a thousand times, and do 800 push-ups... After being captured by the living father for training in the mountains for the 99th time, Shirakawa Nagisa angrily yelled: "So since there are no more ghosts, why do you still hold me to practice swordsmanship every day, you bastard!" Shirakawa Nagisa felt that he had to resist. "Goodbye dad, starting from today, I am going on a long voyage!" He stepped out of the room, his eyes full of pride and ambition. The next second, Shirakawa Nagisa's vision went dark and he fell backwards. When he got up again, the ghost king Wuhan, who should have been eliminated, was walking out of the house where he had just been slaughtered, with his hands full of blood. The man stood in front of Nagisa Shirakawa. When he saw the sword inherited from his second father in the young man's hand, his face turned pale, and he disappeared with a sneer. Shirakawa Nagisa smelled the ghost's scent in the air: "?!" Good news, he finally has a chance to escape from those two living fathers. Bad news, Shirakawa Nagisa traveled to a parallel world timeline hundreds of years later, where the Ghost King Muzan is still alive. In this world, there are few men who can confront the Ghost King, and his second father is already dead. Ghosts are prevalent in the world, causing countless tragedies. Shirakawa Nagisa was holding the knife, his eyes blank. So who is going to fight the Ghost King, him? * The Demon Slayer Team has recently recruited a new teammate. The boy is exceptionally talented. He can lift bricks up and kill ghosts. The most important thing is that the breathing method he uses has almost never been recorded. As bright as the bright moon, as bright as the blazing sun. His figure makes people unable to help but have a vision of the astonishing genius from hundreds of years ago. "He will be the hope of defeating Wuhan." The head of the family pointed out lightly, "Maybe we have to talk to him." In the room, the boy who was said to have the hope of killing the Ghost King carefully placed his two swords on the altar with a pious posture. "Daddy bless you." Shirakawa Nagisa muttered, "Second father, please bless me too." Breath of the Sun and Moon kills the Ghost King (wrong) Invite daddy to get on top (correct) ps: 1.
