Zhang Yanhang's Limitless Universe Skill had after all been upgraded to the Seventh Layer, so even though he still couldn't achieve true detachment of Spiritual Energy from the body, his techniques had become increasingly varied. This time, he was merely trying it out, yet all it amounted to was blowing up an unprotected brain. Had it hit the Lickers' flesh, such a small amount of Spiritual Power would hardly have caused significant damage.
Honestly, if it wasn't necessary, Zhang Yanhang didn't really want to consume Spiritual Power, because compared to the slow recovery of his Energy Value, using his fists would at most just waste a bit of his Physical Strength. Even after fighting for nearly four hours, his stamina was still quite abundant, and he could definitely last another all-nighter without any issues.
