Are you asking for the fist time MC come back home after leaving the country? (To escape from another clan)
If you are talking about the first time he returns home when the Gesun Kingdom is attacked, he meets with his mother on chapter 435. The chapters are not on Gravity Tales anymore, though you can still look up Chaotic Sword God online, and find some chapters somewhere.
The coming chapter after he meets his mom is rage inducing so you might drop this novel like I did so careful.
