Weird Cultivation of Immortality, Starting with a Demon Knife to Grow Mushrooms

When he woke up, Lin Yuan and all humans around the world were thrown into the mysterious world where heaven had collapsed. The techniques for cultivating immortals are all polluted, and every time you practice, you may become deformed and crazy. Others started in a dilapidated wooden house, but he started in an underground cave - yes, he was doing his job, and then he raised mushrooms. What was unlucky was that he opened a treasure chest and was still trapped? ? ? Parasitized! Cave Rating: Special. Upgrade requirements: Mycelium, slime, weird vines... The style of painting is gradually getting wrong. While others were killing monsters and upgrading, he squatted by the swamp and dug clay; while others were flying swords and magic weapons, he was rubbing stone axes and shovels with his hands, and relied on his appraisal function to become an "infrastructure arms wholesaler." Until he fished out a dim silver box from the dark puddle. Open the box and get a whispering demon knife. The unknown parasite in the body gradually awakens. The status bar is clearly marked: [? ? ? Symbiosis]. Looking at the countdown to the weird natural disasters that rotated every month, Lin Yuan clenched the handle of the knife and patted the mushroom field that had just sprouted. "Okay, sword cultivator's dream is broken, sword cultivator can do it too. The road to immortality is cut off, infrastructure farming, fungal symbiosis... I want them all." In this weird world of cultivating immortals where the soul value goes crazy and everything can go crazy, he has only one S-level talent: to always be awake, always sane, and then - to fill this crazy world with his own mushrooms. (Chinese style + survival for all + hard-core farming + weird immortality cultivation, the protagonist's IQ is online, decisive in killing, and the golden finger is unique)
