Yin Yang Needle!
As the name suggested, it was divided into Yin needles and Yang needles. It was a supreme-grade spirit weapon that Wu Chang had spent half of his life's savings and paid a huge favor to forge.
Even for an old monster at the peak of the Nascent Soul Realm, it could be considered a rare treasure.
The Yin Needles could release a lethal poison and a special cold power, causing the enemy to die silently.
The Yang needles could absorb the Yang Qi from other living beings to strengthen one's body. As long as one did not absorb too much at once, it would not cause the Yang Qi in one's body to become chaotic.
Moreover, the stronger the body, the more Yang Qi it absorbed, and the faster its physical fitness would naturally improve.
