The fourth floor of the abyss cannot be unlocked, because the third floor of the abyss is not brushed, and the fourth floor of the abyss can only be unlocked by brushing the third floor. If the second half of the fourth floor is not unlocked, you can unlock the fourth floor of the abyss through customs clearance as long as you kill the boss who is the Zephyr duo. Adventure and Abyss is a pixel-style adventure mobile game. The classic adventure theme, simulated commercial elements, light strategic battle collocation and guild warfare have built a huge and imaginative adventure world for players.
