The torrential Innate Qi poured into Du Ziteng's body from his head, swiftly coursing through his blood vessels, making him feel a warm current descending from his Baihui acupoint, splitting into numerous channels towards his upper stars, five places, and rushing towards his eyebrows, Divine Court, and Qu Cha.
It covered his head and facial organs then poured into his neck's Qianquan, Renyin, Futu, Xinshi, and many other small collaterals (branches of meridians, i.e., the smallest pathways in the meridians) which he couldn't name, and finally filled his trunk.
The invasion of foreign matter made it incredibly difficult to suppress the spiritual power, but Du Ziteng persisted, unwilling to show weakness. As the heat approached his lower abdomen, his spiritual power became more rampant. When the current arrived near his Sea of Qi, he could no longer suppress his internal spiritual power.
