It was a bizarre experience to cultivate in a whale's belly. To a certain degree, this place was even safer than the backroom beneath Jiaotai Palace of Dragon Emperor City.
Only after staying in the whale's belly for a week, due to his great resilience, Zhang Tie had almost recovered all of his traumas, internally and externally. These days, Zhang Tie mainly concentrated on cultivation and introspection.
Zhang Tie had gradually recovered his spiritual energy in his mind sea as the grey fog in his mind sea slowly faded away and finally disappeared after consuming enough spiritual energy. Only after 10 days, the grey fog in his mind sea had already shrunk by 1/3. As a result, Zhang Tie let out a sigh as he realized that it would not be as troublesome as last time when he was struck by the thunder of nirvana; otherwise, Zhang Tie might be driven mad.
