"How much is that knife?" asked Han Sen curiously.
"A hundred million," the blacksmith said coldly, pushing Hen Sen out.
"A hundred million? What material did you use to make that?" Han Sen could not help but asked.
"75 percent Z-steel," the blacksmith said. "Next time you need to buy something, come here directly."
"75 percent Z-steel? He must be exaggerating. With the current technology, we can’t even produce alloy with more than 5 percent Z-steel." Han Sen whispered to himself. He didn’t say anything though since he wouldn’t buy it anyway.
Back home, Han Sen carefully reviewed the dagger. Pulling it out from the wooden sheath, Han Sen suddenly felt a cold breeze. The dagger was eight inches long, its blade green with ripple patterns.
