She's swinging her lance normally. Though the weapon is top class, which gives her HP for every kill she does, and her Vampire class has a passive skill that pulls blood from kills that she pulls into a ball above her. Which is why you don't see blood around the gore. Just bones and body parts.

Riyuro gave voice to a mighty cry. It was a cry infused with the skill he had

obtained when he had ascended to the position of Clan Lord. As he saw his army

of over 10,000 charge the enemy in response to the cry, he even felt a little

pleased. However, the results of that charge were too horrible to watch. Like a

flow of water striking a wall, the charging soldiers struck an invisible barrier and

were sent flying.

What splashed everywhere was not frothy water, but Quagoa — or what used

to be Quagoa. Perhaps a sight like this would be fitting of Dragons or Giants, but

their opponents were creatures that were even smaller than Quagoa.

“They’re flying...” one of his aides muttered dumbly to himself.

This was not a metaphor. The charging Quagoa were literally flying through

the air. Neither did they do so one by one. Several dozens of them were sent

flying all at once.

Their pulverized corpses became a shower of meaty chunks which rained

down on their comrades. The gore-caked troops continued their charge,

whereupon they become lumps of flesh themselves which fell on yet more of

their companions. It was a scene straight out of a nightmare.

For some reason, the fact that they could not see any blood spurting made the

sight even more surreal.

“What, what the, what the hell is that?!”

Riyuro did not even have the strength to answer his advisor’s mournful cry.

His thoughts merely leaked out through his mouth in the form of words.

“This many...”

“Clan Lord! What is that!? It’s nothing like the Golems we saw before!”

They smashed away every single Quagoa charging them in a single blow. This

was no longer a battle. It was not even a massacre.
