The First Question at the Beginning: Bro, You Lost Your ID Card

Nangong Qianyi traveled through time, but he could not remember the memory of his previous life, only vague shadows and some knowledge. He just crossed over and didn't even understand the language of this world. Fortunately, he awakened Tianwen and gained the memories of this world. He should be considered a local now, but he still felt that the vague memories of his previous life were more important. Before Nangong Qianyi could figure it out, he was pulled into the interior of the Tianhe River. Mysterious silver rain, strange pollutants, and unknown challenges were waiting for him. After finally escaping from Tianhe, he found that the classmates who watched the monster together had forgotten their experiences in Tianhe, just like he couldn't remember the memories of his previous life. And there was another figure beside him.
