39. Help you check your body

Liao Ya paced back and forth in the boxing gym, eagerly anticipating the miraculous things her junior brother had mentioned.

Lu Yao, carrying things, returned to the gym and showed a sincere smile when he saw his senior sister.

"I'm back, let's see if this thing is useful!"

Liao Ya was full of anticipation and quickly followed him inside. "What should we do?"

Lu Yao took out the "Portable Ultrasound Scanner": "This device can see inside the human body, let me demonstrate."

When Lu Yao was sick, he had undergone many ultrasound scans and, over time, he had learned how to read them.

He applied "Coupling Agent" to his stomach, then placed the probe on it, and images immediately appeared on the tablet.
