Bab 210: Iron Smelting Hands, Edgeless Mo Mei Sword (2)

Boom!

Streams of aura continuously rippled on the sword.

Outside, Yin Wuyou and Lu Wenshuang stood up at the same time and looked inside.

"What's happening?" The two of them looked at each other but didn't rush in.

They didn't sense any danger. Furthermore, Zhou Shu had said that he wanted to study forging techniques, so they shouldn't disturb him.

"Little Senior Sister Lu, do you think he's forging?" Yin Wuyou asked doubtfully. She could feel waves of heat coming from inside.

But Zhou Shu didn't bring a furnace.

Lu Wenshuang rolled her eyes and harrumphed.

"Call me Senior Sister Lu!" she corrected patiently. "How would I know? Don't you know him better?"

Yin Wuyou blushed slightly. "No, I'm just his superior."

Lu Wenshuang pursed her lips. Anyone can tell what you're thinking.
