Fortunately, Gu Chaliang had adamantly rejected Feng Xiange's suggestion to split up for this expedition. The four of them moved as one, landing on the highest point of the peak, while the explosion tore up the area below. At the moment it was triggered, the four of them had already launched themselves into the air, narrowly escaping the direct impact of the explosion. If it was not for that, these four would have perished in the blink of an eye and walked the roads to the underworld as one, no matter how deep their cultivation base nor how good their abilities were.
Although they were quick to respond by avoiding a direct hit from the explosion and enduring the worst of this horrendous blow, they eventually sustained terrible injuries from the waves of powerful aftershocks that came after that. The Big Four Experts - who had not even fought hand to hand with their enemies yet - had their strengths thoroughly depleted, and their conditions completely worn.
