In that case, Zhou Tian didn't plan to make rule-breaking abilities the main power of the Abyss World for the time being, so he certainly wouldn't let the little beggar destined to be an Abyss World inhabitant practice these rule-breaking abilities.
As a result, after thinking about it for a while, Zhou Tian only transformed the little beggar's physical body to make him possess the ability to fight most strong individuals of the current world, without granting him overly powerful strength.
Of course, since Zhou Tian previously promised to give him invincible strength, then even if it's not truly invincible, it's naturally impossible to only give him the current standard of power. In fact, besides transforming the little beggar's physical body, Zhou Tian also made him the first 'experiment personnel' of a new profession.
