After disturbing the tactical formation, he would catch the tide to explode the whole Formation. The power and damage were so formidable that the tactical formation couldn't compare with.
After the astonishing explosion, the Untainted Land shook. Hongyun in the center of the tactical formation was doomed to die. Meanwhile, he exploded the tactical formation and made a self explode. Since he was caged with no hope of escape, it was better for him to take some of them down on his deathbed. The power of his cultivation was at the level of a Sage-to-be, so it shocked the Heaven and Earth. Adding to the power produced by exploding the tactical formation, it was impossible for anyone to survive.
