To activate the power of the Spirit Taming Bone Flute, Qu Wen Hao needed to employ his own spirit power. Forcibly twisting the Spirit Beast's will was not that tough a task but when the target was such an immensely powerful Guardian Grade Spirit Beast, then to the manipulator, it would pose to become a highly dangerous endeavour.
Although Qu Wen Hao was able to use the Spirit Taming Bone Flute as a medium to twist and manipulate the Spirit Beast's thoughts, but the more powerful the Spirit Beast was, the stronger the willpower and spiritual consciousness would be, resulting in the amount of spirit power that would be required to influence its mind to increase! And even after successfully manipulating the Spirit Beast, the slightest carelessness would have the beast turning back on him instead.
