After years of endurance, gathering power is indeed a strategy of concealment.
However, cultivation is definitely not just about shutting oneself off to invent. Perhaps you can elevate your Realm with the accumulation of resources and Time, but true combat experience cannot be gained through mere patience.
Maybe at the level of True Immortal you can, but which Taoist Monarch hasn't gone through numerous battles to reach this point?
Initially, the Jade Emperor's Realm didn't lose to any Taoist Monarch, even surpassed them, but he couldn't truly wield his combat power. He needed to find a worthy opponent to refine himself.
At first, he encountered the Sword Emperor, but how could such a mighty force be a sparring partner? Every move of the Sword Emperor was lethal. Though the Jade Emperor gained something, it was still too little.
