Naruto System in One Piece - Chapter 485

This is a world of swords and magic. Here, sorcerers and knights are well established, while alchemists and forge smiths are revered by the Empire. Mas transmigrated from Earth to this world and became an apprentice alchemist. This was a very noble status, a brilliant alchemist could command the respect of any major city. Mas was also proud of his own position. But he didn’t expect that his teacher was actually a huge fraudster, who used subpar alchemy products to trick the Royal Capital.

When they came knocking on the door fuming with killing intent, Mas’s teacher Wosk had already run away. While Mas, who was his student, was left behind to deal with this mess. If Mas was unable to hand up alchemy products that are powerful enough, he would be burnt alive by the people of the Great Empire. Just then, he finally awakened the God-tier Alchemist System and received the Creator’s Alchemy Station. On this station, any monster could be created. [Obsidian Gargoyle], [Lightning Naga], [Iron Golem], [Granite Golem], [Puppet Dragon], [Laval Titan]...... One after another legendary alchemy creatures were born in the hands of Mas, and he gradually gained the title of the God of Alchemy!

At home, she was invisible; after marriage, she was a decorative vase; in the end, a sea of flames buried her, and not even her corpse remained. This is the portrait of Han Yuxi’s previous lifetime. Given a chance at rebirth, she strives to improve herself, wishing only to no longer serve as a foil or a pretty face. Then, she will seek out an exemplary husband and live a life of peace and prosperity. Alas, things turn out contrary to her wishes—she marries a man who bears a blood feud and hatred as deep as the sea. She turns the world upside-down, but her road to happiness is strewn with setbacks and the sweetness that comes after bitterness.

It’s a affair between a loyal dog servant and his master.
