"F*ck off!" The moment he penetrated the ground, he got assaulted by tons of monsters that came from every direction towards him.
And his answer was simple, he waved his flying weapons, and started to hit all the ground using his weapons.
The deeper he went, the more monsters he met, and that made quite sense. After all, these monsters were feeding over the power of the gate, and with it getting weaker, it was normal for them to gather closer.
At some point, advancing just ten metres deep was a real challenge! He didn't call back his two monstrous weapons, as they were doing just fine by lowering the pressure off his shoulders.
"I finally got to you," the moment he felt like his tail penetrated into the air, and he knew he had reached the space that had the grand portal. The gate was deeply buried under the ground, and he was sure there was a vast space down below. And he was right.
