Life and Death Pills

One of the pills appeared pitch-black, almost poisonous, emanating a pure deathly aura. 

The other was green, symbolizing boundless life force: Life and Death Pills. Despite their potency, they hadn't yet achieved supreme-grade quality.

"We used the Spirit Opening Pill refining method, but we're far from supreme-grade," sighed the pill banished immortal.

"The Spirit Opening Pill is entirely different from these," Braydon Neal remarked. 

He crushed the black pill, unleashing a deathly aura that instantly withered plants within a five-kilometer radius. 

Then, he crushed the green pill, restoring vitality to the surroundings.

Braydon realized these pills disrupted the path rules. 

He understood why Life and Death Pills were classified as path pills—they encapsulated complete path rules. 

Failing to master this complexity hindered their quality.
