Fa Yi's Sealing Technique was strange. As long as he revealed the technique inscribed on his chest and began plucking his beloved earthen pipa, purple chains would emerge from his body.
These chains could pierce a Jinchuriki's seal, directly bind the Tailed Beast inside, then extract its Tailed Beast Chakra and gradually pull the Tailed Beast out.
The effect was very similar to the Demonic Statue of the Outer Path's chains. At that speed, he could probably extract the Tailed Beast completely in a few hours. Its power was beyond words.
