From the moment Li Xu stepped onto Reality's soil, he became a walking humanoid energy emission source.
The Golden Core was the core of this energy, with vast amounts of free ions from the ionosphere densely surrounding him—none dissipating, none dissolving.
Due to the ionosphere, any technological device that used electricity or had electronic components would easily be destroyed once it came close to him.
That was the case for objects; it was no different for people!
Indeed, anyone who entered an area where the electric charge was exceptionally active and sporadic electrical sparks burst into existence would feel the same.
Moreover, these anomalies were only the beginning!
Standing still was already astonishing enough, but once he moved, an energy vortex would seem to spring out of nowhere!
It sounds exaggerated, but it's consistent with scientific laws.
A Li Xu like this was truly forbidding to strangers.
