Outraged, Drake decides to go after Tang. Upon infiltrating Tang Towers, he discovers Tang's true scheme: to use the artifact to reap the souls from the Spirit Realm and use those souls to power his cyborg army. Drake then breaks into Tang's secret morgue facility and recaptures his clan members' souls. He then travels to the basements of the facility, where Tang is using the artifact to open the portal to the spirit realm. Drake fights and defeats a demon-like creature, but the Ghost Assassin steals the Soul Portal Artifact and escapes into the spirit realm. Drake enters the realm and pursues the assassin, ultimately defeating him. He then retrieves the Soul Portal Artifact and collects the Master's soul.
