As the purple colored internal energy slowly circulated forward, it would encounter some minor obstacles. With just a bit of added strength, he could break through those obstacles. Lei Yu really enjoyed his success – the way his internal energy flowed, it was like cutting down anything in his path whether it be soldiers or generals (metaphor). When arriving at a meridian, there would be another barrier blocking him, similar to a defending warrior. Usually Lei Yu could pass through leisurely, but if he used too much force resulting in his meridians fracturing, pain would be felt. Then the green energy would immediately activate, repairing the damage. After countless fractures and repairs, Lei Yu’s meridians had enlarged several times, becoming tougher and more flexible than before.
The spiritual energy in the air was being absorbed by the circulating internal energy. And the yellow bead in Lei Yu’s brain would immediately transform into a gas, acting as a filter for the newly absorbed energy from the air, removing all the impurities, making the spiritual energy become extremely fine and pure.
Lei Yu currently has three types of forces in him: the purple energy being his own used to cultivate his abilities; a green energy that would work behind the scenes to repair any damages to his meridians and other acupuncture points; and the yellow energy that will remove impurities from the spiritual energy he absorbs from the air.
