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. [Ding, your shadow has killed an ant, you have gained experience points and ability points.] [Ding, your shadow has successfully killed a dragonfly, it dropped a dimensional box.] Crap, even killing insects can also increase his experience and get him rewards. What else!
The mature different spaces mentioned by the sea breeze whale actually pointed at the countless different dimensional planes in every major region of the Origin World.
They were similar to the Fifth Dimension, Sixth Dimension, and Seventh Dimension on his Earth. They contained all sorts of fantastic oddities which far surpassed anyone's imagination, but it wasn't like Earth where they had only a few stable different planes.
As for why the whale insisted on using the word 'mature'?
This was the most important point. Only those dimensional spaces which had stabilized over countless years, having not collapsed for several thousand years could be considered as mature different dimensions.
People weren't willing to enter dimensions which hadn't stabilized. Well, besides the few extremely formidable lunatics who didn't care much about their life.
