The Legendary Mechanic (WN) - Chapter 1037 - Gaud’s Headache

Eren Idril died as an old, decrepit, and piss-poor adventurer by the maws of a D-Rank monster. He had a lot of unfulfilled dreams and desires that couldn't see the light of the day after the light in his own eyes died down.

But fortunately for him and unfortunately for the world, that wasn't his end. Eren was somehow dived back in time when he was a mere teen, attending Lionheart Academy for adventurers.

When life gives him a second chance, Eren decides to exploit it to its fullest. Experience his vile deeds as he partakes in them without feeling the slightest bit of hesitation.

In the vast and boundless continent Cangtu, there were ancient sects governing the Ten Old Domains, unworldly immortal clans beyond the Blue Sky, and primordial demon gods dominating the dark abyss that together created a great number of brilliant stories over the long course of the history.

In this very world, there was a boy, named Lin Xun, who embarked on his journey to the pinnacle of strength alone through cultivation and spiritual tattoo inscribing.

Escaping alone from the Mine Prison where he had been living since he was adopted by Master Lu, Lin Xun knew nothing about his identity but the little information his adopter, Master Lu, had told him. With two ancient spiritual tools Master Lu gave to him before the destruction of the Mine Prison, Lin Xun started his journey to Ziyao Empire, where he is supposed to find out the truth of his lost Spiritual Vessel and the person who slaughtered his family, leaving him orphaned.

Will he be able to unlock the mysteries of the two magic treasures, unveil the secrets of his identity and create a legend of his own?
