The cultivation of the Five Thunder Righteous Law was not going smoothly for Chu Zheng, as his internal organs were struggling to cope with the Five Elements Primordial Qi.
Each breath he took felt as if his heart was scorched by fire and his lungs were cut by knives, causing considerable damage to his organs.
Although his organs gradually toughened after repairs through the interface, the pain reached deep into his bones.
Sweat poured from Chu Zheng's forehead like a spring; soon, a puddle formed beneath him.
The five-colored spiritual energy flowed in and out of his nostrils, entering his Dantian and then reaching his organs where it slowly refined the Five Elements Qi.
Through constant repairs, Chu Zheng distinctly felt the changes in the spiritual energy of the surroundings; compared to the outside, the fluctuations of spiritual energy inside the Small World were more noticeable, gradually becoming sparse.
