Ace didn't think there would be different kinds of Golems besides Speed Golem, and this one didn't have apparent weakness like Speed Golem.
But there was indefinitely a weakness because with his heavenly sense he can feel the same peculiar Qi as Speed Golem coursing through this Golem as well.
With some more observance, Ace finally found a focal point where this Qi was resonating. It was right at the center of this Golem's chest.
After making sure there wasn't any loophole remains, he dashed toward the Golem. He leaped toward the Golem's chest and stabled his long sword right at the area which was probably the weak spot!
The Black Blade Long Sword pass through the Golem's chest like butter, and Ace suddenly felt something crashing. But he still quickly retracted the long sword and quickly put some distance between Golem.
