Du Heng didn't turn his head, so he didn't see Xu Pinglin and Gu Ping's expressions, but he clearly saw the family member on the other side.
His eyes moved slightly, and as his mind stirred, he bent down again to examine the old man's abdomen.
When examining beneath the navel, there was a very obvious pulsation on the centerline of the navel, and this pulsation continued to the CV-04.
Du Heng paused for a moment, carefully observing the pulsation, and found that it wasn't from the navel towards the CV-04 but started from the CV-04, rushing upwards.
Now Du Heng understood. Cold qi was attacking the chest from the CV-04, causing the old man to faint around midnight and noon.
Moreover, this discovery made Du Heng's heart jump.
The navel is called the Spirit Gate Tower, the place where a person's original qi gathers. The evident pulsation now meant that the original qi was about to escape.
Furthermore, the qi surging upwards was a sign of insufficient kidney qi.
