Capítulo 514: Now That's A Hell of An Experience!

Just before the demons were wiped out, the Terrorblade Abyss Lord — the only demon Baiyi had eyes for — silently slipped back into the realm crack and fled. 

As a high-level demon that had spent its life in the hostile environment that is the Abyss, the Terroblade was very intelligent, unlike the lesser demons it commanded. One look at the terrifying wall of black flames was all it took for the Abyss Lord to understand that it could not face Baiyi head-on, so it turned tail and fled.
