Leonel's momentum was undying and extended into infinity. 

After he killed the first elder, it was like his spear began to tremble with hunger and greed. Having tasted the blood of a supreme expert once, it wanted to taste it again. 

The pressure on him plummeted at first, but then it seemed to multiply. This wasn't only because these old fossils suddenly felt a true threat to their life, but also because of the logistics of the battle. 

Leonel's size, when compared to them, was quite literally an ant to a human. They were too large. 

Trying to fight in the skies like this when Leonel was just a small target was part of the reason Leonel had been able to continuously find flaws in their battle style. 

The moment one of them fell, not only did their fury rise and their sense of seriousness become heightened, but it was also one less large body in the skies to contend again.
