Supernatural Chat Group, Starting with Zhao Yun's Inheritance

Yu Jie, originally a man from the 21st century, died suddenly due to staying up late and came to a world parallel to the earth. He thought he was reborn and could experience a wonderful high school life, but the appearance of a WeChat chat made him discover that the world is not that simple. Fortunately, there is a necessary system for time travellers, but who can tell me why it is martial arts? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
