Nightmare Submarine

The power of intelligent creatures comes from understanding the world. Human beings analyze the real world to create science, and explore the spiritual world to create mysticism. When the glory of the whale oil steam engine illuminates the world, the nightmare sea hidden under the curtain of reality becomes darker and deeper. Depth 0: Friends, put on your [Bourdon tube depth gauge], we are about to start diving; Lv1 Depth 1-9: Didi! Reality begins to peel away, but as long as you remember that "dreams are just dreams", you won't die randomly, probably... Level 2 Depth 10-49: All the "unrequited" things have turned into daydreams here, giving birth to countless kinds of "inner ghosts": [Noble Master], [Invincible in a hundred battles], [Golden Finger]... And even [Protagonist]! Lv3 Depth 50-99: Warning, you have completely lost touch with reality, please do not believe in any common sense anymore. It is normal for people to have no heads, pigs to fly, and rabbits to like to eat tigers... Depth:... Depth 999+: Feathered Serpent, Eternal Proverbs, Platinum Moon, One with a High Crown... Many indescribable things whispering in disordered timing. Depth: Unknown, this is no longer a dream, but another "real world"! Mr. Will Drake awaits your dreams in his eternal mansion: "Friends, welcome to my country. Don't be afraid, you are just sick, and those things just now were all hallucinations.
