Sam's hand is in a partial fusion mode with wind element as he moved his pen.
His opponent, actually the second fastest finisher who wanted to become Sam's opponent is trying to his best to add more runes to the runic barrier, but just looking at the speed, Sam is going, he is cutting it really close.
At that moment, a third person came out of his own runic barrier and joined in with the second to make it difficult for Sam.
They thought both of them working together will give them an edge. However, they realized the situation… remained exactly the same. They are cutting it really close. Sam is clearing the runes just as fast as they are making them.
Their lead is just a few runes.
When the fourth opponent came in and joined, they finally saw a change in expression in Sam's face. Until now, he has been doing it with one hand, but with this new added opponent, he had to work with both of his hands.
Once again… they are cutting it really close.
