I, the Navigator, Travel Through Cthulhu

"The seventh conch begins to sing, and the dead will return to the world." When Chen Changping woke up, a rough hemp rope hung around his neck. On the ancient book spread out in front of me, the moss-green characters are growing on their own. He found that he had changed his body, with a growing carapace fragment embedded in the back of his neck. Non-human scales began to grow on his wrists. The oceans of this world are dark red. There are three moons in the sky. The bell tower rang seven bells, and everyone on the dock turned their heads at the same time, with a faint blue light in their eyes. The old man said that people like him are called "Yuan ones". What secrets are hidden in the church? Why does the ancient book control his body? The body is becoming something else. Is this a gift or a curse? ——The only thing he is sure of is that he must survive to find the answer.
