Niwan Palace

Niwan Palace (泥丸宫), Chinese acupuncture term located around the head泥丸宫
If you drew a line connecting the ears and another line from where the eyebrows met to the back of the head, the place they connected was the Niwan.
This place had many names. The Niwan, the mind-sea, the divine palace, the soul depository. There were all kinds of names, but they all referred to this place. In the cultivation world, it was said that even before a fetus formed, its Niwan was born. Even before a baby formed, its Niwan existed. The Niwan represented the soul. First came the soul, then came the body.
So naturally, when people's heads were heavily injured, their souls would dissipate, causing them to die in both mind and soul. It was due to the collapse of the Niwan.
Unless a person's Spiritual Strength was extremely powerful, below the Soul Transformation realm, a cultivator whose Niwan was destroyed would definitely die.
This was an extremely important place and also an extremely weak place. But this was where he was supposed to condense the Divine Gate Star.
