A week had passed since Han had finally managed to access the secondary lightning chakra pool on his body by loosening up the shackles on said chakra pool. This was only possible due to his extreme and chakra straining method created by Han that left his chakra coil pained, and he couldn't sleep right for a few days till he got used to it.
After a week of constant strain he had finally lossened up his chakra enough to try and break the connection between both of his primary and secondary sources, joining them together.
"Alright here we go."
Han said as he sat in the lotus position, mediation, while he thought it was useless for him, was actually a big help since it allowed him to restore lost chakra quickly. Also thanks to the growth of his previously weak chakra to a very potent chakra caused his body to strengthen pretty quickly, his muscles healed faster and his overall physique was boosted farther than imagined due it. Now his strength could be compared to A really bad Jounin or a war promoted jounin who is just knocking at the door of special jounin level.
His consciousness moved through his body as he felt every path and vein in his body, his chakra reaching to every section of his body and the source. The source was a small blue fire burning at the top of his abdominal area, radiating with life.
He focused all of his usable chakra at one stop as he felt a small error, a small dent near it.
"That must be the entrance."
He thought, Han carefully guided the chakra near the dent before jamming it all at the dent in one moment, barely damaging it.
"Ha.... This is too difficult."
Han concentrated the chakra in a pointed fashion as he took the pointed chakra near the gates.
"Lightning."
Han transformed the chakra into the lighting nature as it had the most piercing power.
"Haaah."
With a large battel cry he jammed the chakra in the dent, causing a small hole to appear.
"Just one small hole, that like 75% of my chakra." he thought.
The scene transformed as the chakra slowly seeped out of its den in high pressure, crackling like lightning as it mixed with Hans original pool, forming a Mixture of the both.
Soon after Han left the mediative state and felt lightning chakra distributing all over his body. He pumped a higher amount of chakra to his body, small cracks if lightning appeared.
"This is simply... Amazing."
He observed his body carefully, it felt stronger and faster, faster than he could fathom, every nerve in his body felt faster as he observed his surroundings in slow motion.
He always wondered how the Raikage's avoid tunnel vision, now he knew the answer, They observed everything in slow motion.
Han took a sprint in the same state as he was previously, feeling a lot faster than he used to.
