The Key to Death

Legend has it that there are nine pieces of keys to the gate of hell. Eighteen years ago, Liang Tian's father's body entered the gate of hell, and the gate of hell was closed. From then on, the barrier of yin and yang was broken, and evil spirits were rampant. Eighteen years later, Liang Tian walked out of the mountains and devoted himself to opening the gate of hell again and rescuing his father. Enter ancient villages, break taboos, fight evil spirits, dig out the truth... I finally managed to collect nine yuan for the key, but it turned out that I couldn't open it at all. Is it possible that the legend is false?
