It was necessary to comb through the not-so-large but somewhat intricate web of relationships again.
Mike Smith was one of the five contacts left to Yang Yi by his father.
Yang Yi first got in touch with John Jones, but John Jones died.
After the death of John Jones, without a guide, Yang Yi once tried to contact Mike Smith, only to be informed that Mike Smith had also died. So Yang Yi did not continue to try and contact Mike Smith; instead, he got in touch with David at Hong Kong, who then introduced him to Danny.
After meeting Danny, Yang Yi entered Pelican Bay Prison, where he learned of Brian's existence. Then, Yang Yi helped Brian escape from prison.
After Brian's escape, he recalled his two subordinates but was also pursued by the CIA.
