Looking at the huge rock that Thor was lifting, Jack's eyes were blank, and no one knew what he was thinking.
Jack was actually estimating the weight of the rock.
If it was really made of rock, then it was very likely to be heavier than any equipment he usually used for training!
Scratch that, it was definitely heavier than the weights he usually used for training!
The size of the stone was almost as tall as Jack!
If it was solid, to be able to lift it directly would require extremely strong core strength and arm strength.
Even if he was a tier 6 knight, he didn't dare to say that he had absolute confidence in lifting such a rock.
Now, seeing that the little girl could lift it without any effort at all, "what the f*ck!" was his only thought.
Was this the cub of some advanced pure-blooded magic beast?
This strength was simply not something a human body could possess.
