Golden Core!

Looking at the sudden surge in progression for [A Humble Heart], Di Tou wanted to go explore that, as he recalled the last time he had checked, he hadn't even passed the fifteen percent mark, but before he could worry about that, one of the long unmoving surges of original Qi started moving.

Back when Di Tou was in the Qi Condensing Realm, he condensed ten streams of Qi. After he had reached the Foundation Building realm, the Qi he had access to far surpassed ten streams, but the ten original streams weren't used like ordinary streams of Qi, but instead went to various parts of his body to reinforce him, seven of the streams of Qi directly settled, going to his brain, heart, kidney, liver, lungs, spleen, and stomach, while an eighth stream dispersed into his Spiritual Sense, leaving him with two strands of Original Qi that sat stagnant in his body.
