Chapter 4 - Help from the Guidebook
In front of those fireballs are those Goblin Monsters unable to protect themselves. All those Monsters got killed by those fireballs. You can only see that area got burned by those fireballs and currently, a huge hole has been created in that place.
David controls the game character close to that place to see if he will get anything from it or not. First of all, he did not know how to get exp crystals or stat crystals. So he thought killing those Monsters could give him those crystals. Normally in all the RPG games you can see killing Monsters will give you some kind of loot.
Unfortunately, when he came close to that place he did not find anything. Now that makes him dejected.
'How am I supposed to collect those crystals if I cannot get them after killing those Monsters?'
David did not know how to get those crystals. In the system remark, he told him that he would be able to get those things after killing Monsters. In front of him, he was unable to find anything.
'I should try to kill more Monster to see if I can get those crystals or not,'
David decided to kill more monsters to see if he would get those crystals or not. There is a chance that he would need to kill a huge amount of Monsters to get those crystals.
With this, he controls the character to search for more Monsters. It did not take him that much time to find 5 Monsters. It looks like those Monsters trying to approach his direction as they already notice him.
Without giving them any time to react, David instantly uses a fire bullet attack. Every time he activates the fire bullet technique, 5 bullets will instantly get created and directly go toward those Monsters. The moment one bullet will heat anything it will instantly burn that thing alongside the same bullet it will pierced through that thing.
The same thing also happens with those Monsters. The defenses of those Monsters are not enough to protect themselves from those bullets. One by one those bullets begin to pierce through the body of those Monsters. In the next second those Monsters also begin to burn.
Like this, he once again kills those Monsters and once again approaches that place to see if he got anything after killing those Goblins or not. Unfortunately, once again he did not find anything. Now this time he did not know what to say.
