Originally, the Great Doctor didn't think about it at all.
He just thought that when the seventh needle, which was also the most critical one, was finished, he needed to take back all the seven silver needles in a flash!
Only in this way could the curative effect be reached from the end of life to the extension of life.
However, when he wanted to acupuncture, he suddenly thought of William's last sentence.
It was an inexplicable sentence.
"If you want to beg me for a needle, I need you to kneel and kowtow three times! Five of you prostrate in front of me!"
"That boy, since he has such a brilliant medical skill, the last sentence should not be groundless."
At the thought of this, the Great Doctor began to wonder if his needle was really that mysterious.
This was indeed the case for this test!
the Great Doctor was a master of Transforming Strength!
What's more, he was a Deduction Master.
It was easy for him to take out the silver needles from his body.
