That wicked black sword had actually forcibly entered Fang Xing's Sea of Consciousness. This was such a strange occurrence that even Fang Xing didn't expect this. For a cultivator to accept a Sword Embryo required the guidance of the cultivator's spirit sense, after all, which meant this was a choice that required both parties' assent—the Sword Embryo gets to choose its owner, but the cultivator also chose their desired Sword Embryo. This was precisely the reason why Fang Xing could be rejected by all the other colored swords, yet even though Fang Xing didn't want this strange black sword, it had managed to force its way into him and become his Sword Embryo regardless.
