The first day Cain wanted to comprehend this simple yet complex statement, it caused a powerful headache that nearly threaten to split his head in half. 

For any other mere mortal cultivator, these Chaos Words would have smashed their Spiritual Sea apart. Even Divine realm cultivators wouldn't be able to escape their Spiritual Sea from collapsing. 

Cain could tell that even his unfathomable grandmother would be powerless against Chaos Words. After all, her soul sense is simply unable to ever perceive the principles that lie within Chaos energy. 

Only Cain, because the Chaotic Emerald created a permanent link within his soul's core, could he continue to perceive Chaos Words. 

The splitting headache he experienced on the first day gradually change to a more comfortable sensation. 

As of today, Cain could finally perceive Chaos Words with a calm expression.
