I can only remember the MC obtaining an gigantic Axe inside a ruin and other people wanted to snatch the axe, instead some of them get cleaved by the axe. When the MC wanted to leave the ruin, some OP Antagonist/Rival wanted the MC to kneel by pressuring with it realm or power-whatcha it, instead the MC stood firm despite the pressure and walk out a bit shakey. I remember some of the spectator seems to mention 'They might have made a terrible enemy in his/her heart'
Martial God Asura it was when his enemies were in the heaven realm after meeting zi ling in the monster mountain
I am of the same thinking as the rest, that it is Martial God Asura. His Axe is called Asura Ghost Axe. This arc starts around 389 Aptly named 'Avarice'. He gets the axe earlier, but that is when they have already returned with it, and they desire to snatch it.
That is also somewhat similar with something that happened in Wu Dong Qian Kun. The only difference is that the weapon that the mc found is a halberd not an ax.
I'm also leaning towards Wu Dong Qian Kun. People found A Nirvana stage cultivators tomb and went to raid it. In the main hall MC notices something special about the weakest weapon, a halberd, and manages to snatch it. Then some antagonist want to snatch it from him and in the end an even stronger antagonist (stronges of younger generation in main family) tries to pressure him into kneeling. MCs willpower prevails and he manages to walk out instead. It might be around chapter 180?
either WDQK and LD got pressured by LL when he got his halberd or MGA and chu feng under pressure when he got his Asura Ghost Axe
