Is it feeding or fusion? This needs to be confirmed, but if Zheng Yichen were to choose, he would definitely pick the Savage World. Although there's no significant energy level there, the strength level is high enough.
A sturdy body brings a sense of security.
Without sufficient energy levels, all those seals or other miscellaneous means would be impossible to use.
Without an entity like an Ancient Venerable that can directly break through the environment, no matter how formidable the strongmen, they'd still have to resort to hand-to-hand combat here.
In this place, while the body might be slightly weaker, other aspects are overwhelmingly strong—it's truly like a fight among demigods. Although energy is abundant, naturally forming passive protection.
However, the body here is just too fragile. In terms of Inner Strength, Zheng Yichen is not known for having an exceptionally long Blue Bar.
He's the sort whose Blood Bar far exceeds his Blue Bar, able to convert it during combat.
