When the Monarch's Heart was taken out, the Apocalypse Martial Ruler became displeased.
It made him recall the time when the Tempest King defeated him.
More importantly, it was only a clone of the Tempest King that killed him back then.
"Crack!"
Chu Kuangren shattered the Monarch's Heart in his hand.
Just like how the Supreme Honorable's Heart he previously used could allow his cultivation level to increase temporarily, the Monarch's Heart had the same effect too.
Suddenly, Chu Kuangren's power grew steadily.
It quickly surpassed his current cultivation level, and he was incredibly close to breaking into the Monarch Realm!
Having been strengthened by that newfound power, the Dragonslayer in his hand hummed and trembled, releasing never-ending waves of ferocious qi everywhere.
