Yellow

When Azure boasts that becoming a venerable will let him dominate the world and Green warns him not to look down on heaven’s will, it is Yellow who turns to Purple, their advisor, and asks what he thinks. Later, after Blue fuses with a fragment of the immemorial blue heaven to research heaven’s will and falls deep into a dream realm, Yellow reports the failure to the rest of Shadow Sect with deep pain. ^{ch. 1016}

Inside Northern Plains’ Earth Trench, as Green’s life-and-death immortal aperture formation explodes around him, Yellow grabs Green’s hand and drags him out over his protests. Yellow points him to the surviving rank eight immortal materials, all saturated with heaven’s will, and tells him only a complete otherworldly demon can go fully undetected; Green should give up the attempt and start over. ^{ch. 1017}

Sword Immortal Bo Qing failed his tribulation and was barely saved by Yellow, though the injuries to his soul only worsened over the following thousands of years, reducing it to a soul sphere that Shadow Sect kept sealed in Central Continent’s Earth Abyss. ^{ch. 1026}

After the seven destroy a Gu formation guarding Limitless Demon Venerable’s true inheritance, Yellow laughs and credits Purple: “As expected of Purple, you are really amazing.” Yellow asks Purple his wisdom path attainment level, and on hearing “great grandmaster,” reacts with astonishment that Purple is the first among them to reach it. ^{ch. 1371}
