549 Ten Seconds Made Him a True Hero

Ling Ran had obtained the Skill Serum from a treasure chest after completing the Self-Improvement mission.

Compared to the Skill Serum he had obtained before that lasted for two hours, the small Energy Serum only lasted for ten seconds, a ridiculously insignificant period of time.

This was because Ling Ran had not found the right time to consume the content of this small, purple bottle. For some time, Ling Ran actually felt that this small Skill Serum served no purpose other than to let him experience how it felt like to possess Legendary Level skills.

But after thinking through, Ling Ran decided that this was not the case.
