The Eight Transformation Systems of Battle Through the Sky

After many years of planning, Shi Tian successfully proved that he was just a waste in this society, so he died fighting against the potential energy of gravity. When he woke up, he found that he had actually traveled to Dou Qi Continent and obtained a system that could change his destiny. "What, I can actually transform, and I can transform eight times!" "Damn it, why are six of them useless!" "Oh my god, you can only change once a day!" It took Shi Tian eight days to study and understand his abilities, but he never expected that the novice benefits would only last eight days. "Dog system, I said I was going to become a prehistoric Titan, are you deaf?" Zhang Wuyi, who turned into a tree, was in despair. His fruit fell and hit an old man passing by. "Why did it fall?" The old man wondered. "Give me the answer to gravity first. I did it on purpose!"
