System? What System? I'm Not Familiar with Him!

This book is not systematic? Heroine] [Warm reminder, this book has sufficient plot logic, so you can read it with your brain! Xu Feng traveled through time! Well, from the most appropriate perspective, it should be time travel! The good news is he has a system! The bad news is that this system seems to be too simple. Not only is there not much introduction, but the total description is only a few words! But, although the system is simple, its functions are still very practical! And he found that the system seemed to be able to be upgraded! With the help of the system, although Xu Feng's level is low, it doesn't matter, he can call people! "System, I want to summon... Tianlong Chengyun-Zhao Yun!" "System, I want to summon... Chunyang Sword Immortal - Lu Dongbin!" "System, I want to summon... Monkey King, Monkey King!" However, when Sun Wukong was summoned, Xu Feng was stunned. No, I know that monkey wearing a purple gold crown, wearing gold armor, and holding a golden hoop, but what the hell is this rag doll Sun Wukong with a sealed mouth? ? ? Until one day, Xu Feng discovered that what the system needed was not a spirit stone, but a natural spirit! After discovering this, Xu Feng made a bold decision Which place has the most spirit? That is of course the entire world! "System, I want to sacrifice the entire world! Call Pangu" The moment Pangu's phantom appeared, Xu Feng suddenly discovered that Pangu's phantom seemed to be stared at by something. He looked up and saw a pair of huge eyes reflected in the sky! That's... The true form of Pangu in the heavens! ! ! He stared at the Pangu phantom summoned by the system across the boundless void!
