They were all still running to get as far away as possible from the explosion. Even though they were far enough, they could still feel the heat and shockwave from the explosion.
Even after a few seconds, the heat and wind waves continued to spread around.
None of the buildings, houses, and plants around the blast zone survived. Everything was devoured by the heat.
What is happening right now is so similar to the explosion of a nuclear bomb dropped in the middle of a city. Even though the actual effect wasn't that bad, anyone who saw it would definitely think that the explosion was not much different from a nuclear explosion.
They finally stopped after about a minute of running at full speed dodging the blast. They turned towards the blast.
The hot wind was still blowing on their faces. Make them squint their eyes because of it.
