If I Can Cultivate My Fire Power by Myself, Will I Become the Emperor of Fire?

In the world of Blue Star, the era of disaster has arrived. For a time, disasters occurred everywhere and strange beasts appeared. Among humans, a small number of chosen people have become superpowers to fight against strange beasts and keep their peace. Time has passed to a peaceful period, in this era where everyone can become a strong person, young Chen Nan has awakened an F-level power that is rarer than S-level. He can be called a walking boy with kidney deficiency. For a time, ridicule and abuse towards Chen Nan came like a tide. Chen Nan, who was ridiculed by many, just smiled slightly when he looked at the awakening time system in front of him. Just a little bit of wind and frost... No, system, are our charges a bit expensive? ? ? [Host, please rest assured, this system will definitely allow you to pay one price and enjoy double the service] [In the first year, your fire power entered the demon world and floated aimlessly...] [In the tenth year, your fire power encountered a three-headed demon flame dog, attached to it and wandering in the vast space...] ... [In the 100th year, your fire power has successfully evolved into magic flame, and the quality of the host power has been upgraded to S level...] In front of the system panel, Chen Nan fell into deep thought as he looked at the flame powers that had been brought into all the worlds to continuously practice independently.
