Yet with the fierce and loud explosions, the thick and bright fireballs coming out, he could now see for hundreds of metres inside.
He threw a hundred grenades around as a test, distanced them to test his ability to control their detonation. The closest ones to him took a few seconds to detonate, while the furthest ones took close to half a minute.
This made the explosive noises happening continuously for a few minutes as if the world was going to end. And just after the first minute, he could see lots of fog getting purified and eaten away, clearing the areas affected by his grenades' fire and turning them into normal land.
This looked as if a rodent was eating a cookie piece by piece. William watched all this with surprise. He never expected that by using light and lightning elements together, they'd produce such marvellous effects.
It wasn't just limited to the devastative power of this attack, but also the purifying nature accompanying each explosion. As for monsters, be it crocodiles or other monsters, they ended up getting killed under such fierce attacks.
The grenades exploded and released massive balls of fire at first, then they started to expand outwards, spreading fire over a large area of the swamp.
The fire that expanded wasn't able to repeat the same purifying effect of the initial explosion of the grenades, yet they were domineering enough to threaten the lives of any living creature within the swamp.
"Damn this kid! What the heck did he make?!"
"Is there a grudge between him and us or what? Is he trying to kill us?!!"
"These grenades... They aren't like anything I've ever seen before. It's great I recorded it!"
Just as the grenades exploded, the watching masters were all shocked, but didn't stop themselves from running away. When the fire spread, it covered up areas of many kilometres, enveloping them if they didn't move out a bit earlier.
Watching the infamous grenades for their uselessness releasing such mighty explosions was an eyeopener for all of them. They were already recording what William was doing, and that meant the process to produce these grenades were already recorded as well.
Yet they didn't get the main trick that turned such weak grenades to be like this. After all this would be over, they'd return back with these recordings and start showing them to Artisans. They'd try to mimic what William did, producing much stronger grenades than what they used to know, but nothing close to what William did.
As for the latter, he kept standing on the edge watching fire spreading into the foggy area. One hundred circular areas were cleared totally of fog, monsters, and swamps, showing a rugged terrain with lots of holes, ridges, and charcoal black coloured soil.
William went to examine these areas where the fire receded and died down. The fog didn't return to cover these regions, as if it feared touching them or something. As for the swamp areas touched by the scorching fire inside the fog, they still were covered with fog, much thinner than before, yet it was still there.I think you should take a look at
He couldn't tell how much his grenades explosions affected and changed the world inside the fog from his spot, but he could tell things were looking much better than before.
"Hmm... These regions look normal as any other spot in the world," he examined the cleansed areas thoroughly, trying to get the full scoop of his grenades, "that means the centre of my grenades' explosions will change to normal. And that will be a forbidden area for monsters in the fog..."
He started to think deeper about how to use this to his advantage. He couldn't tell if such an effect would happen at the innermost zones of the fog or not. But at least he secured a safe and resting spot for himself during his march in the swamp outer areas.
The moment he realised this; William didn't hurry to continue his advance. Instead, he retreated, started to make more grenades.
At first, he thought of them as a means to kill his way towards the inner zone. But now, he took it as a way to further protect himself. So, he spent one more week making more grenades, ending up doubling the amount he already had.
"I'm ready now," William walked towards the fog area again. This time, he knew what he had to do. The moment he stepped inside, he didn't fight back any monster and just jumped around, gathering as many of them as possible.
At the same time, he kept getting deeper, not moving in circles in the outer zone. After gathering up enough monsters, enough to the extent he couldn't handle anymore, he started to throw out his grenades and then detonate them.
He made sure to dash multiple times before activating them. Then he used the time lag before their detonation to further expand his distance from monsters.
The masters following him learnt their lesson quite well, keeping themselves away from the reach of these explosions. When William moved away, they started to run as well, getting as far away from him as possible.
"Hmm... I didn't get many cores... My grenades are that fierce to evaporate even cores," after doing this for hours, William muttered to himself while collecting the few cores after the last explosion.
He was now standing in a wide space that his grenades created inside the fog. Since he learnt about his grenades' unique ability, he started to throw these grenades together at the same spot, ending up creating a spacious area void of fog.
He was now resting there after long hours of running and fighting. At first, he was able to outrun these monsters without the need to fight back. Yet later on, faster monsters appeared, and they increased in number, enough to block any possible retreat way for him.
William had to fight for his life from time to time, to escape the tight encirclement imposed over him by the monsters.
