Travel Through the World Starting with Proficiency

Waking up from the hungry and cold slums, Han Fei only breathed his last breath. In a desperate situation, the "Proficiency Panel" suddenly appeared - once you get a permanent certificate, your efforts will be rewarded, and you will become infinitely stronger! … And this is just the beginning. Under the panel, there is actually the ability to travel through the world hidden: When he opened the door for the first time, he fell into a future city like a steel forest, opened the first pot of gold from the garbage recycling station, and opened the martial arts sect with silver from another world; Crossing over again, in front of us is the ethereal world of cultivation, refining elixirs and longevity elements, just to build the foundation of immortality in the mortal world; When the door opens for the third time, the continent of gods roars with magic and divine authority. Faith burns, the Kingdom of God rises, and the road to immortality is at your feet... Worlds opened up in front of him. Han Fei used the panel to experience the worlds and nourished himself with the worlds. From barely surviving to traveling all over the world, this journey has no end— Every door he opens is reshaping his destiny.
