In the hurried ten years, the five Grotto Heavens of Li Shiming accumulated a certain amount of energy, and his combat power was greatly enhanced due to the increase in energy in the five Grotto Heavens and his mastery of his own abilities.
After testing, the time he could stay outside the Grotto Heaven was two days, and after two days he would be repelled by heaven and earth, and Heavenly Thunder would descend.
He stayed outside for two days, and when he sensed the power of Heavenly Thunder, he didn't dare test it himself but returned to the Grotto Heaven.
Fortunately, the Grotto Heaven was right beside him, ready for him to enter anytime.
He finally understood why the Great Powers did not dare face Heavenly Thunder, as the power of Heavenly Thunder was so strong that even with the 'Heavenly Human Technique' and the blessing of the Heavenly Human state, they did not dare withstand the attack of Heavenly Thunder.
