章 38: 38. Portable Color Ultrasound Device

In the courtyard of the martial arts school,

Lu Yao was practicing boxing under Liao Ya's supervision. Agile as a vigorous macaque, he leapt here and there, throwing punches and kicks, and before long, he had completed a set.

His progress was extremely noticeable; yesterday, when he finished, he was so exhausted that he could barely stand, but today, he was just a bit out of breath.

While practicing boxing, Lu Yao also did not forget to train under "pressure," occasionally stealing glances at his senior sister's majestic high-rise buildings.

Liao Ya seemed oblivious, admiringly commenting from the side,

"Not bad, with the blessing of Spirit Refinement, you've indeed made rapid progress. You have achieved a small success in Sinew-Strengthening. I understand now why all the masters like disciples with talent; teaching them is truly worry-free!"
