Adam wanted to catch the attention of the Giant Goblin Beast and got as close as he could to it and ran near its path at a speed that was lower than his full speed so that it could be easily followed by the Giant Goblin Beast.
The Giant Goblin Beast as it stomped over the forest and left a trail of destruction spotted a small figure moving at incredibly fast speed and went to stomp on it.
Adam saw the stomp coming and it was relatively slow, so he had enough time to jump up into the air and the Giant Goblin Beast couldn't change the target of its stamp that hit the ground where Adam was previously running.
Despite nearly being hit by the Giant Goblin Beast, it had turned out just like he had wanted and Adam landed upon the foot of the Giant Goblin Beast.
The beast's foot alone was the size of many cars put together and Adam stabbed it with his dagger to see how much damage he could deal the beast.
