Ryo finally finds a person who can read Yuanda Zhu's letter, which said "Find Master Chen for help". Ryo finds Master Chen and asks him about Lan Di, the man who murdered his Father.

Ryo is forced to fight Guizhang Chen from Chen Family, to save Nozomi who Mad Angels have taken as a hostage. In hopes that Goro finds Ryo's secret message, he fights Guizhand Chen, ending with Ryo and Guizhang both wounded and defeated.

Ryo meets Lishao Tao, the person he was looking for. Lishao, a martial arts master, easily defeats Ryo and tells him to go home. Thinking he lost because he does not have enough strength, Ryo goes around Hong Kong to find a martial artist.

Ryo and Ren successfully sneak into the Yellow Heads' headquarters to rescue Yuanda Zhu. But the Yellow Heads all knew about their plan to sneak in. Surrounded by their enemies, the two fight Yuan who is one of the leaders of Yellow Heads.

Ryo finally reaches Lan Di, the man who murdered his Father. Blinded by revenge Ryo viciously attacks Lan Di. Lan Di easily dodges Ryo's attacks and leaves. Yellow Heads' Dou Niu realizes his plan has failed and attacks Ryo.
