Of the ten bodyguards under Great Heaven, Sword10 was the one who had learned everything but not specialized in any particular direction. Meanwhile, Sword9 had trained exclusively in rapid speed.
Apart from Wind Elemental Enlightenment, he was also an expert in a speed type god rule. Not only that, but the direction of his Sword Dao cultivation was also more focused on rapid speed. Over 70% of the sword skills he had mastered were of the speed variety.
Despite Lin Huang giving it everything he had using Seraphic Speed divine ability, lightning and light attribute skills as well as rapid speed sword skill Thunder Eclipse, he was barely able to follow Sword9's speed.
As Sword9 had his body imbued with Wind Elemental Enlightenment, he was physically invisible to the naked eye in the battle.
In the void, all that could be seen was a dark red electric arc that flashed continuously as if it were fighting something invisible.
