The Extreme Alchemist of the Mighty Cauldron - Chapter 302 - : Imperial Beast Garden

Year 2056, in a city in the Yuan Jiang Su Jin area. On top of a ruined, shattered six story residential apartment sits a teenager wearing a combat vest, militaristic trousers, and alloyed battle boots. On his back is a hexagonal shield and equipped is a blood-shadow battle knife. He sits there silently on the edge of the roof. At this time, the sparkling sky was shining and there was a refreshing breath within the air that blew towards him. However, there was only silence within the ruined, deserted city, with an occasional howl that makes your heart skip a beat.

Zavier met Cosmic Consciousness after his death. He was satisfied with every system that Cosmic Consciousness exhibited, so he wanted all of them. Surprisingly, the Cosmic Consciousness obliged him.

Zavier was reborn in an isekai full of magic and alchemy. Now, he had many routes to upgrade. Interestingly, to coordinate these systems, Cosmic Consciousness gave him the gift of being able to duplicate himself. He could clone a finite number of himself to manipulate these systems.

Jiang Xiaoxiao, the great master of the Mystic Sect, was born with an incomplete soul. Every full moon night, she would also turn into a tiny three-inch tall person.

The Grand Master said that in the sixteenth year of her life, she would meet a nobleman. The purple gold dragon aura on the nobleman’s body could lift her curse.

Xie Xun, the King of Chu, had his dragon aura taken away at the age of three. Plagued by bad luck, he was exiled from the capital.

The first time he met his adorable wife, his adorable wife shrank with a swoosh in front of him into a tiny three-inch being, standing in his palm dozing off.

Later, the King of Chu sewed a small pouch on the sleeve of each garment. When going out, he would put his adorable wife in the pouch.

And he told others, “My little one is weak, pitiful, and helpless.”

The little ghost shivered in fear: Have you seen someone using a kitchen knife to hack ghosts at a mass grave? Yes, it’s your weak, pitiful and helpless Queen!

The ghosts wailed at the mass grave: Have you seen a living person who could scare the ghosts to tears? Yes, it’s still your weak, pitiful and helpless Queen!

The entire netherworld exploded: Have you seen a newly wedded bride escorted by two Ghost Emperors and two Ghost Kings? Yes, it’s still your weak, pitiful and helpless Queen!
