“I will look up into the sky on this wasteland and fight for our civilization!”Xu Mo was accidentally transmigrated to an apocalyptic world. He quickly learned that his parents had just passed away and he was being hunted.Not only that, but his only uncle was trying to take away the money his parents had left for him.In order to protect himself and his younger sister, he steeled his heart and decided to walk down the dangerous Path of Evolution.“Energy, magnetic field, dark matter, radiation… All of these are now known as Source Power!”By absorbing the Source Power, one could evolve their body, activate uncharted brainpower, awaken abilities, and even create weapons.One could even travel through the vast universe if they got powerful enough.For Xu Mo, who had just started to absorb Source Power, he started to realize that he could see things that others could not.

Li Xuan traveled through time and had no system or plug-ins. He could only live in a small mountain village temporarily. However, one day, he was mistaken for a hidden master and he had to become his disciple.

As an upright person, Li Xuan didn’t want to lie to others and sternly refused, but the other party offered him too much, so he had to make up a set of training methods to fool him–as a result, the apprentice succeeded in practicing!

Looking at his disciple with thunderous muscles and strong blood, Li Xuan was stunned: “I made it up, how could I succeed in cultivation? What kind of monster are you?!”

At this time, Golden Finger appeared: “Your apprentice has started to practice the exercises you made up, and you have directly mastered the exercises, and your strength is a hundred times higher than those in the same realm!”

ps: The book “I’ve been at home for a hundred years and I’m invincible when I go out” has been ordered with a high order of 20,000 yuan. If you find it interesting, you can go to the old book to read it ^_^
