First Legendary Dragon: Starting With The Limitless System - Chapter 4: Mark of Fate

Sian Lee, the strongest person under the heavens in old china, was reborn as a very overweight woman.

Having transmigrated to a new world and becoming an ordinary Blacksmith in a Blacksmith Shop, Ye Feng shortly has the Master Blacksmith System activated.

By coincidence, Li Yunmu found a super machine from humanity’s age of darkness. From that point onwards, his ordinary life would never be the same! Aptitude? Innate talent? What are these? Could they be eaten?

I have neither aptitude nor innate skill, but my shadow can level up using hacks. Experience, Ability points, battle prowess… all of them could be hacked. Even while he is asleep or tired, he could still increase his skills.
