Picked up a Little Werewolf

[Due to the massive destruction of the environment by humans, serious pollution has occurred, and animals and plants have undergone mutations one after another. As time goes by, humans gradually cease to exist, and are replaced by mutants. When Lang Xun was chasing a mutated tiger, he accidentally fell into a time rift and traveled to the 21st century a thousand years ago. When he fell from the sky, he accidentally injured an "ancient man" who had just climbed to the top of the mountain. Gu Shengsi was cheated on by her boyfriend. Feeling sad and distressed, he decided to go hiking in the middle of the night and use the first ray of sunshine in the morning to heal his wounded heart. However, when a person is unlucky, drinking cold water can fill the gap in his teeth. When Gu Shengsi climbed to the top of the mountain, before he could catch his breath, he was knocked unconscious by an unknown object falling from the sky. Gu Shengsi picked up a homeless young handsome boy with silver hair. The young handsome boy was well-behaved, polite, and beautiful, but his brain seemed a little hard to use and he seemed to have some mental problems. Gu Shengsi: "What species do you think you are?" Lang Xun blinked his big eyes, his eyes full of seriousness: "I am a wolf, white wolf." Another example... Gu Shengsi asked him: "How old are you this year?" The pretty boy replied: "180 years old." Looking at the young man in front of him who was several years younger than himself, Gu Shengsi nodded calmly and said, "Then you look quite young..."
