Too much was as bad as too little!
To be more precise to Eric this experience was just like someone who was on drugs. It felt too surreal at first, and when he understood it was real, the excitement in his heart had already surpassed the limit.
He was on overdose at that moment, and it wasn't anything good for him, or for his heart, and path towards the peak.
If one wanted to climb towards the peak, the most important things were an impervious will and a stable and steady heart.
For someone who strived towards the peak of not only Earth but also the Origin World, and the whole living being, these riches were nothing more than dust and dirt.
It didn't mean that these materials didn't have value in his heart, it was just that these things weren't as precious as he took them to be at first.
