What Can't Be Broken and Closed?

Brother Wang Hao opened a door in Lop Nur that should not have been opened. The price was to gradually lose all memory within seven days until death. Before he died, he left his last words: The door can only be closed from the inside, don't let Peng Fei go in alone. But Peng Fei decided to go - close the door and bring back the fragments of his brother's consciousness. The being on the other side of the door is awakening, and the countdown has begun.
