Eternally Regressing Knight - Chapter 544 - The Fervor

A child was born unable to cultivate Inner Strength. In order to gain his father's attention and regard, he resolutely chose the painful and difficult path of cultivating Outer Strength. As spring gave way to autumn, time flew by, and the child grew up... he became a young man. What truly changed his destiny was a mysterious Crystal Stone formed from a meteor—the Meteor Tear. This Meteor Tear, unbeknownst to the young man, merged into his body, and like a caterpillar transforming into a butterfly, the young man metamorphosed... And with that transformation, everything changed. And his father finally came to realize the astonishing strength of the son he had never truly invested his Heart Power in...

She is a descendant of an Ancient Chinese Aristocratic family. Having just transmigrated into a young lady’s body filled with aphrodisiacs, she had no choice but to pounce at a random man upon arrival.

The enchanting and beautiful big brother’s mouth lifted up into a demonic smile, spitting out cruel and sorrowful words. “Take it out, don’t leave an intact corpse!”

The cold second brother with the icy eyes continuously bled alongside the dying and suffering man.

Their eyes were purple and enchanting. They were this world’s devils, banished by the people.

When they gained strength, they retaliated by destroying the heavens and exterminating the earth.

She was a girl who mistakenly entered another world. She’s their salvation and is the only one that must be obtained at all costs.

Overbearingly possessive and absolutely unrestrained indulgent pampering as long as she stayed by their side.

A gentle as jade man, a faint and dedicated guard.

There were those who liked it silent.

What is the type of love?
