Gu Laozu was in his study dealing with documents at that time.
Gu Tingyun got straight to the point and candidly said, "Grandfather, I want to become stronger!"
Upon hearing this, Gu Laozu looked at his grandson, who had now fully grown in stature.
He was tall with long legs, nearly as tall as his father, but his personality was even calmer, unruffled by honor or disgrace in his dealings.
Without asking the reason, Laozu said, "I can arrange for you to go to the training base to practice boxing and do physical training."
"Okay!" Gu Tingyun nodded in agreement.
After he left, Gu Laozu used a special line to make a phone call.
"Old Gu, calling so late, what's up?" a voice come through the phone, cheerful and hoarse with age.
Gu Laozu chuckled, "The kid at home has grown up, and I'd like him to train at your place, see if it's convenient for you?"
