Time Travel MC: but Only I Have the Nei System

[Minecraft] + [Group Transmission] + [Module] + [Resource Reduction] + [Cthulhu Elements] + [Multiple Heroines] The world is about to be destroyed. Some adventurers chosen by God suddenly come to the MC world where monsters are everywhere and supplies are in short supply. They don't know how to face it! In the previous life, the protagonist, who was an old MC player, came to this world with the nei (jre) system that can evolve and increase permissions! Others eat carrion, and the protagonist eats barbecue. Others use wooden swords, and the protagonist uses a craftsman's soul weapon. While others were studying Tinker's Soul, the protagonist was already flying around in the sky wearing IC2's quantum armor. When others started to study IC2, the protagonist smiled evilly, "I'm not familiar with industrial technology!" Ever heard of magic? Come! Eat my king's treasure! Wait, you said you took refuge in the ancient gods and learned magic? Sorry, my authority is above yours! /Killxxx Interspersed with some Get Up Wars, Hunger Games, Hunter Games... Only the protagonist can synthesize it freely, others must obtain the formula first, otherwise they will not be able to synthesize it even if they know how to synthesize it (similar to the mysterious era where you have to solve the notes) [The first stage: Craftsman's Soul, Industry 2, Gaia's Grimoire, some monsters in Terraria; the second stage: Twilight Forest; the third stage: Mysterious Age 4, plant magic, witchcraft]
