Fifth update!
Ye Chenfeng and his two companions were not killed by the explosion in the cave. The moment the grenade detonated, the ground beneath their feet surprisingly gave way and they fell through, avoiding the effects of the blast.
After plummeting for a good seventy to eighty meters, a splash echoed as they landed in water—they had unknowingly arrived at a river beneath the cave.
Think Tank outside the cave felt puzzled, cautiously stepping forward to the edge, only to discover that it had collapsed inward. He glanced down into the dark, seemingly bottomless pit.
"Ye Chenfeng, you won't survive this!" Think Tank said, a look of joy spreading across his face.
Upon submerging, an ice-cold chill invaded their bodies, causing all three of them to shiver uncontrollably.
Fortunately, all three of them knew how to swim, and they had prepared oxygen tanks in their backpacks well in advance, so being underwater was not an issue.
