Shadow Hack (Novel)

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 can still increase his skills.
