System: After Time Travel, I Want to Become a Top Expert

"I, Pei Ming, was reincarnated after the war in ancient times." "Once a swordsman." "Now, it seems the same is true." "I am in the age of the end of law... In terms of strength." "Probably still the best swordsman in the world." Late at night, Pei Ming wore cyan casual clothes and took a black car to a research laboratory in the mountains. After the car door opened, Pei Ming casually threw the black robe on his body to the entourage behind him. Resolutely walked towards a man wearing a white robe. Pei Ming said softly: "It's been a long time since I joined Tianqi. Why are you looking for me today?" The man in the white robe bent slightly and whispered: "... Your Majesty... There is a nuclear bomb with a yield of 500 million. There are some problems that we can't deal with. I just... I'd like to trouble Your Majesty." This novel and its characters are purely fictitious.
