[Novel Introduction]: My name is Su Mu. My story begins on a cross-country graduation trip with University A alumni. There is a mysterious tycoon investment behind the trip, but the reality is that it is delicious food and beautiful scenery, and you can also travel with Fu Ziyu, who has been in the same school as your childhood sweetheart for ten years (at least that's what I think) but has never spoken to. I think when I return to my motherland, my life has just begun. The last stop was the desert, but something unexpected happened. We encountered strong winds in the desert and fell into the quicksand. Looking back on all the doubts in our hearts along the way, we realized after falling into the quicksand of death: the temptation of travel is like a gorgeous death, tempting the prey to go deeper and closer to death. When the companions closed their eyes and waited for the death knell to ring, they found a space in the darkness where they could survive, a huge underground palace. Are they saved? A group of people burst out laughing with joy as they survived the disaster. However, how should we get out of this paradise in the darkness? Is it the laughter of an angel or a devil? Su Mu could sense the fear in it... Oh my god! Someone tell me what's going on...
