Perhaps Rui had gotten so immersed in the flow that he had actually reacted late when that flow changed abruptly. Perhaps, the change was extraordinarily abrupt that it was just that difficult to handle.
Rui wasn't quite sure.
But there nothing was quite like the eminent threat of death that brought out the very best of one's creative ability.
CRACK!
Rui grimaced as he intercepted the closest root attack with his sword, yet, rather than trying to slice or destroy it. He almost instinctively applied an incomplete version of the Flux Earther.
He intercepted the impact with his sword, his arms limp before progressively stiffening ad pushing back as the Root moved in closer to strike his body.
Just like a spring pushed back harder when compressed.
And just like a spring, it pushed his entire body backward at a remarkably high speed. Rui didn't try and ground the kinetic energy by using the second half of the technique with Reverberating Lance.
CRACK!
