Yes he will. The awakening of the body he possessed is not yet complete. Once the awakening is complete he become really powerful. Though his lungs will keep exploding since it can't withstand his power. And because of lung cancer. He went straight to SS. But before awakening he will get dragon lungs to strengthen his lungs and use abilities so others doesn't suspect he is faking his S rank status

for those who have read the novel, does he get strong eventually or does he stay weak?? i thought he might slowly find a way to get stronger but he still cant do anything after 69 chapters ┗( T﹏T )┛
