Before his eyes, the pitch-black little box formed a miniature vortex within his domain. It spun so fast that it directly produced layer upon layer of afterimages.
It pulled a black ring straight through this semi-vacuum domain.
Combined with the little black box's water- and fire-resistant, incredibly sturdy material, that speed alone was enough to cause considerable damage.
But in front of Leo, even a missile could be forcibly held down, let alone such a tiny black box.
Leo took a few more steps forward and reached out to grab it. Although the little black box dragged a series of phantoms through the air, it was still seized and yanked into Leo's hand.
The powerful impact it brought with it actually forced Leo to extend his right hand, stretching his entire palm by roughly two centimeters.
If that tremendous impact had struck the ground, it could have sent a tank flying. Yet in Leo's hand, it could only tremble slightly.
Once Leo truly got his hands on it, he could sense through his touch that this material, this texture, and this weight made it the heaviest substance Leo had ever encountered.
Unlike Thor's Mjolnir, the Uru Alloy used to forge Mjolnir was not particularly heavy. Although its density far exceeded that of gold, it was still bearable.
The weight that made it impossible to lift was mainly due to the divine power sigils Odin had attached to it.
But this tiny metal box before him had a fairly obvious hollow feel. Even so, its density was indeed more than a hundred times greater than that of Uru Alloy.
This metal block in Leo's hand was no bigger than a tissue box, yet it weighed nearly a thousand jin. It was an extremely exaggerated figure, and its density was unprecedentedly high.
