The Green Light Forest

Free parks are nothing unusual for many children, with lakes, rockeries, small bridges, and amusement facilities, and countless tourists. For Bei Nan, even lying in bed with his eyes closed, it feels as if he is there. He is a roller skater and goes to the park every night. One time, on his way back from his grandmother's house, his bicycle broke down, and he planned to lock it in a free park by the road.
To his surprise, this park actually does not allow minors in. What secrets does the park hold? The park keeper, with a stern face, just told him to leave quickly.
Bei Nan is someone who will not rest until he gets to the bottom of things. He circled the park and finally found a small exit, sneaking in quietly.
This park is like all parks, nothing unusual, but what is strange is that no matter where you go, it feels like there is a dark cloud hovering overhead, making one feel cold.
As he approached a well covered with a thick cement slab, he could hear cries for help from inside. Bei Nan approached, and a pale hand reached out from the gap in the cement slab.
