Li Yi shook the entire survival base with the Dragon and Tiger Power, and the people within the base thought they were under attack by a strong enemy. They rushed out, but judging only by their auras, none of these people were weak; their strength started at the Spirit Tribulation Realm.
After passing the tribulation, like cultivators from the Xuanxian Continent enduring the Heavenly Tribulation, the whole person transforms from a body of flesh into a higher life form. Even if not dual-cultivating, their strength surpasses that of an Earth Demon.
If dual-cultivation methods are applied, then there is no upper limit.
"Where's the enemy? Who is invading the survival base?" someone shouted in alarm.
"Such a commotion, is it an enemy of Great Demon level? What's going on with the Intelligent Brain's defense system, why hasn't it been activated, the enemy is already over the base, and the formation hasn't been triggered either." Someone else raised a question.
