Before killing Moge, Su Xin was already considered a colossus in the Martial Arts World. However, at that time, Su Xin's reputation was more or less on par with Shen Wuming and Di Jingfei, at best his background was stronger, and so his status was somewhat higher than theirs.
But with Su Xin's slaying of Moge and later collaborating with Xiao Chuo and others to take down the Xiao Family Ancestor, Su Xin's reputation grew day by day, to the point that it could even be said that with his strength, he was fully qualified to stir up a considerable storm in the Martial Arts World.
Therefore, the current Su Xin was no longer just a local giant, but a Jianghu colossus! Not only in Northwestern Province but even in the Central Plains Martial Arts, Su Xin was a significant figure.
If someone else were targeted by the Great Joy Arhat, a powerhouse of the True Martial Realm, it's likely they would be scared half to death.
