Targeted by GM? the NPC at the Beginning Was Forced to Repair

On the night of the blood moon in July and a half, Chen Xing accidentally traveled through the global popular game "World", but unfortunately became an NPC in the novice village.

It has been detected that the host has extraordinary qualifications. It is necessary to take "Postpartum Care of Sows" in order to build the foundation?" Just when Chen Xing thought the system was extremely unreliable, a year later the game invaded reality and he returned with a full level of cultivation. However, before China could be happy, the global crusade army had already arrived at the city: "That cultivator is the final BOSS!" The National War broke out and alien civilization arrived. When Chen Xing finally broke through the shackles, he found that the secret book of immortal skills was signed: Institute of Ancient Martial Arts, Chinese Academy of Sciences... ——It turns out that the magic that saves the world comes from a gift that he personally traveled back to the past?
