A metal box was opened.
A silver-white metal arm, exuding a strong sci-fi vibe, was thus revealed.
The metal arm looked incredibly heavy, but in reality, it was quite light.
Wang Haihua picked it up with one hand: "This thing is made of Primordial Alloy and weighs only fifteen kilograms."
As he spoke, he placed the arm next to Qian Rui's severed arm.
Liu Hei hopped over and, with lightning speed, pecked Qian Rui on the forehead.
"Boom!"
Qian Rui seemed to hear a thunderous sound, and he instantly fell into a dazed state.
The researchers watched in horror.
Everyone saw thin strands of flesh suddenly sprout from Qian Rui's severed arm, directly embedding themselves into the Mechanical Combat Arm.
Frankly, the scene looked a bit disgusting.
A few seconds passed.
"Crack! Crack!"
The five fingers of the mechanical arm suddenly began to move rapidly.
Each finger moved at least ten times per second, so fast that even afterimages appeared.
Wang Haihua couldn't help but gasp.
