Inside the hot spring of the Necromantic Space Castle, Chen Yu relaxed his body, letting the scalding water flow over him.
Whether it was extracting the world's rules by the Sanzu River Bank to forge a divine rank, or using the power of the Storm Divine Core to aid Ni Nasu in summoning a typhoon to stop another typhoon, both tasks had drained Chen Yu immensely. Though the latter seemed relatively effortless, controlling a divine rank with the power of a demigod was still no easy feat.
Moreover, Amaterasu's appearance forced Chen Yu to re-evaluate his entire plan. Combined with his initial mental exhaustion, Chen Yu's thoughts had become chaotic.
While energy potions could invigorate the body and eliminate fatigue, they only addressed physical tiredness. The accumulated pressure on the soul and spirit could not be relieved by such remedies.
