end of his life. Yang Lin had several adopted sons; they were all well-skilled in the military or martial arts. When he first met Qin Shubao, he was impressed by Qin's martial arts strategies and military tactics. As a result, Yang Lin asked Qin to be his 13th adopted son. Qin thought it was a great opportunity to revenge for his father Qin Yi, so he became the Yang Lin's 13th taibao (太保, adopted son). However, he never had a chance to revenge since Yang Lin was much stronger than him. Later, Qin escaped from Yang Lin's home and joined the rebellion in Wagang Fort. Yang Lin was very angry after knowing one of his adopted sons betrayed him. He asked his troop to attack Wagang Fort, but unfortunately, just before Wagang Fort's collapse, Wagang Fort's smart officer Xu Shiji (徐世勣, or Xu Maogong 徐茂公) subverted Yang Lin's assistant general Tang Bi (唐壁 in the book, or 唐弼 in real history).

Yang Lin was the one who came up with the idea of Yangzhou's martial arts test. However, after the plan was proved to be a failure, Yang Lin and one of his adopted son, Yin Yue (殷岳), was ambushed by Qin Shubao and Luo Cheng. Yin Yue was killed by Qin Shubao during the battle, and Yang Lin was hurt by Luo Cheng. It was a great time for Qin Shubao to revenge for his father, but Qin decided to
