In fact, more than thirty years ago, Su Yu had already secluded himself and never left Mechanical City, nor had he contacted anyone.
Since then, rumors have spread that Mr. Su Yu went mad!
Because Mr. Su Yu added some inexplicable, strange things to the exchange system.
For instance, Demon Warrior, War Demon Mechanic, Data Ghost Demon... such eerie professions.
There were even "Energy Seed" exchanges corresponding to these professions, allowing rapid fusion to ascend to the Third Rank.
Initially, many people hesitated to exchange for these professions after seeing the information, as they appeared very peculiar and not quite right.
But soon, some couldn't resist the temptation and chose these professions.
They had no choice, as mainstream professions were too challenging, progress was incredibly slow, and holding a ritual to ascend to the Third Rank was even harder.
