The Taiyi Sword could have continued its fight with the Demon Slaying Sword, but in the end, it submitted.
In fact, when Shen Mo persuaded it, the Taiyi Sword Spirit was already moved. It just needed a stepping stone, a reason to convince itself to switch allegiance to Shen Mo.
During its struggle with the Demon Slaying Sword, it viewed this sword as merely a junior. Yet, this junior was able to contend with it for several days and nights without a clear winner. This was enough to prove that Shen Mo's previous words were not exaggerated, and his Proficiency in Swordsmanship was no less than that of Senior Gu Song.
Recognizing Shen Mo as its master, it couldn't deny this was a good way out!
Consequently, the Taiyi Sword simply went with the flow, finding an excuse to retract its sharpness, thus putting an end to this struggle.
Shen Mo faintly perceived the Taiyi Sword Spirit's thoughts and recalled the Demon Slaying Sword with a smile.
