Su Yanxin heard this and chuckled softly as she took out something flesh-colored from her ear.
"This thing?"
Zhao Qitian's expression darkened a bit.
At the same time, he became more alert inside.
"What is this?"
"Oh, this is a little gadget developed by a doctor friend of mine, for fatigue resistance. It contains herbal medicine components. Don't believe me? How about you smell it?" Su Yanxin handed the flesh-colored item, which looked like a chess piece, to Zhao Qitian.
Zhao Qitian became interested after hearing the three words 'resistance to fatigue'.
Taking the flesh-colored object, he sniffed it below his nose and indeed detected a faint scent of Chinese herbs.
"I've used it for a while, and I feel quite alright. Do you want to try? You just need to stick it in your ear or behind your ear, and it works well. Moreover, it's waterproof and one can last for a long time."
"That magical?" Zhao Qitian examined the item skeptically.
