I cant get through the pyramid level because I cant interact with the door of the snake woman and I also cant interact with statues that require spirits and I can go through some walls.
Go to the north room first, go through the maze, avoid traps, and get something. The story of UNBIRTH gold can be triggered in the vault. After returning to the last entrance, I met two brothers and sisters, which can swell her. Then come to the maze, rush through the magic circle with 0 soul pregnant (otherwise you will be teleported back), and then go to fight the BOSS. BOSS has two battles, the first is relatively simple, the second, you need to attack the soul to get the skill expansion bOSS, then break her invincible status, and then attack it.
