Seven Days Guild Tower

In the shadow of the bustling city, there stands an apartment called "Seven Days Huihun Building". It does not appear on any map, but only sends invitations to people with "karmic debts" at specific moments. Shen Qingmo, a famous architect, became a new resident of this building because of a mistake in his design drawings, which resulted in an irrepayable life debt. Here, the supernatural is the real law of physics, and despair is the air we breathe every day. All residents have sinful karma, and the building spirit will tailor a seven-day "atonement ceremony" based on each person's karmic debt. The mission was to deliver letters for seven days. As long as seven "warning letters" are sent, you can get out alive. But when I saw the list of recipients, I felt like I had fallen into an ice cave—the names of all my closest relatives were written on it. The recipient of the seventh letter turned out to be myself. "It turns out that I am the chosen 'keeper of the building'."
