MTL - Solo Leveling (Only I Level Up) - Chapter 335

The world experienced a cataclysmic change, and countless spatial gateways appeared out of thin air.

Exotic beasts of all shapes and sizes swarmed out of those aforementioned spatial gateways, forcing the humans to face the crucial moment for their survival.

In order to search for a chance at survival, brave warriors from the army and scientific researchers risked their lives and entered the world beyond the spatial gateways. To their surprise, they discovered that there was a chance of obtaining beast cards by killing these exotic beasts in their world.

Those with extraordinary spiritual strength are able to utilize the beast cards, perhaps transforming the cards into the beasts’ combat bodies while they were still alive, or transforming them into weapons or defensive gears, or…

A new occupation came into existence following the changes, known as beastmasters.

A transcender with two souls fused into one found himself in this magnificent new world full of waves, rising step by step as he ascends into the seat of a godly beastmaster.

~•No Escape•~“Are you running away from me, my sweet girl” spoke a voice in the hallway that made her stop in her tracks. The hallway had turned dark with only the wall lamps that burned brightly casting the shadow of the man on the floor as he slowly emerged from the other end.“What are you doing here, your majesty,” She said and bowed immediately as she saw him approach her with slow but steady steps.“You haven't answered me, sweet” The man said with a sweet smile that made her wary and he heard the way her heart skipped a beat. He stood before her and used his index finger to raise her chin. He tilted his head as he gazed into her green eyes that looked back at him with fear.He took a step forward closing the distance between them and his eyes narrowed when she took a step back, but that didn't stop him from cornering her.“Did you think you can escape from me?” He continued to question and she didn't miss the mockery behind his words.“I…I” she felt her words tied to her tongue because of the man's daunting aura. She felt him trace her forehead with his finger down to her jaw. He continued moving his hand down to her neck and to the top of her swell and her thudding heart hitched when his hand continued to stay there.“Did you think you can escape from me?” He bent towards her as he spoke. His breath fell on her neck which sent a jolt that traveled down her body.“I told you, you're tied to me and me to you”_______________________Perdita Kartar was a winsome yet strange young lady.
