The lungs reside in the abdomen and diaphragm, thus they are called Hua Gai.
This is also because the lungs are located at the highest position within the body's organs and perform the function of covering and protecting the organs, fending off external evils.
Hua Gai Siqing, as the name suggests, refers to exhaling the turbid and inhaling the pure, expelling the old and accepting the new.
When this talent was unlocked, Zhao Ya felt an unparalleled transparency in his body, and a simple breath could penetrate deep into the internal organs, giving a sensation as if reaching down to the heels.
It is said that the breath of a true person reaches the heels, while the breath of ordinary people reaches the throat.
This means that someone who has achieved success in cultivation can feel the breath reaching the heels with just a simple breath, while ordinary people, no matter how hard they try, can only take shallow breaths.
