I'm in the World of Cultivating Immortals, Playerunknown's Battlegrounds

[Welcome the host to travel through the world of immortality. [Please host, choose any three from the following items to help you survive in the world of immortality. [Yin and Yang two-gas bottle: The bottle has its own Taiyin pole fire, which can be filled with people and turn into slurry water in an instant. [Immortal-killing Flying Knife: Bow to the gourd and say "Please, baby, turn around", and then the flying knife will be sacrificed. Under the saint, no one will survive. [One Billion Soul Flags: It forms a world of its own, and can refine all living things into souls. Once shaken, the heaven and earth will spin, and gods and ghosts will cry. [The Immortal Palm Vase: seizes the creation of heaven and earth, absorbs the light of the sun and the moon, the green liquid in the bottle can promote the birth of all things, and has the miraculous effect of living dead human flesh and white bones. …… Lin Fan looked at the choices given by the system and frowned slowly: "System, are you sure you want me to survive in the world of cultivating immortals? Instead of letting me kill my way through the world of cultivating immortals?"
