Ye didn't hold any doubt; Nan Feng would always do something beyond his expectations, and she seemed confident, so he just followed her.
Before Nan Feng headed to the river, she first cut a large piece of bamboo, drilling a hole in the center, thus, making the bamboo a long pipe.
She had seen a small story about Su Doupo on television before: During the Northern Song Dynasty, Su Doupo once wrote a letter to Deng Shou'an in Guangzhou, where he mentioned the water supply issue in Guangzhou. Consequently, Deng Shou'an used ten thousand pieces of bamboo to invent a water supply system for Guangzhou, resolving its water supply issue.
Nan Feng thought this idea could be copied.
Latterly, Nan Feng went to the river, inserting one end of the bamboo pipe into the river, and pumping air from the other end. As the air was evacuated, water spouted from the other end.
Seeing this, Ye's eyes flashed with amazement.
