In a Perfect World, I Am the Great Inspector of the Yin and Yang Realms.

The day Emperor Huang Tian fell, the day Qin Yang was born. He is a time traveler. He was a descendant of an ancient martial arts family in his previous life. He was proficient in Baji, Muay Thai, and Sanda, and majored in physics. In this life, he was born on the border of the wilderness. He was born with supreme bones, but there was another inheritance hidden in his body - Zhang Fei Martial God. A roar can shatter the stars; five divine chains can judge all enemies in the world. The zhangba snake spear is directed towards it, ignoring defense, unable to dodge, and unable to respond. What's even more deadly is that he combines physics with ancient martial arts killing techniques, turning every attack into a precise fatal formula. When the nine heavens and ten earths collapsed, darkness and turmoil swept across the heavens, and foreign lands and immortal realms fought on the ruins, Qin Yang did not wait for Huang to return. He chose to rise up with a spear in troubled times, killing to stop killing, killing until the dark creatures did not dare to land, and killing until the immortal king of the fairyland did not dare to honor him. "He has been sleeping for half a million years. I will carry half of these half a million years for him." This is a road from the frontier of the wilderness to the top of the heavens. It is also a road that belongs to the Yan people in Qinyang. ——There is no room for naivety in troubled times, and I will break it with my own spear. I am the inspector of the two realms
