Sam could feel all his meridian network going numb for a moment. He wouldn't be able to circulate the energy normally like that.
After closing his eyes and taking a deep breath, Sam noticed a huge threat that is looming over the cocoon and also a fierce attack that was going to hit him.
But he didn't hurry. He still had his eyes closed and the spiritual energy started moving all over his body, he is not using the meridian network, rather using the muscle fibers to circulate the energy, he might not be able to use elemental attacks because it would be torturous to convert the spiritual energy into elemental energy without flowing through the meridian network.
But the elemental attacks are not the only cards up his sleeve. His arsenal is full of so many attacks that he didn't even have a chance to use them at all.
As he concentrated, all the spiritual energy started concentrating on his vertebrae. It accumulated along the spine, of course over his skin.
