Zhang Bin naturally understood why. The True Qi of ordinary cultivators might come from consuming certain spiritual medicines or using spirit stones. However, he cultivated the Qingmu Longevity Technique by absorbing the Spiritual Energy of countless plants. This process endowed his True Qi with medicinal properties, earning it the name Longevity Qi. It was capable of healing people and extending their lifespans, with endless wondrous uses.
Longevity Qi could also be transferred to the bones through the muscles, but the effect was ultimately not as good as applying it directly. Since a Pine Needle came from a pine tree, it served as an excellent conduit for Longevity Qi. That was why Zhang Bin used a Pine Needle to deliver Longevity Qi and treat Xu Lao'er.
However, the villagers all stared, dumbfounded. They couldn't believe their own eyes. How could a pine needle possibly pierce muscle? It was simply incredible.
Could it be that Zhang Bin's master is an Immortal?
