Xiao Man's electronic tattoos begin to glow at night, metallizing plants wherever they walk. Su Wanqing finds bloodied scales by her daughter's pillow - from the mechanical beast she scratched in her dream. Chu Yun modifies a sprinkler into a purification truck, but the sprayed liquid accelerates the mutation instead.
Dr. Shen ventures to take a blood sample from Xiaoman, and the microscope shows that the blood cells are devouring the metal particles. Blood-colored text suddenly surfaces on the community bulletin board, "The perfect container is ready."
The fifth energy tower rises from the schoolyard, and metal wires hang down from the top of the tower to wrap the children into cocoons. When Xiao Man used his ripple ability to free his companions, his own right hand was entangled in the silk threads. Su Wanqing cuts through the threads and discovers that her daughter's arm has the same kind of mechanical eye as Dr. Lin.
Lu Li's Regulus sword suddenly goes berserk, and a holographic map pops up from the hilt - labeled with the locations of all the energy towers that make up the meridian map of the human body, and the community is right at the heart.
Dr. Shen cracks the blood code and discovers that Xiaoman's genetic chain hides a backup of Dr. Lin's mind. Chu Yun uses metal vines to bind the rampaging mecha, and Su Wanqing rushes into the core of the energy tower with her daughter in her arms. The inner walls of the tower are etched with parent-child photos - all of Su Wanqing and her mutated offspring from a different time and place.
"You're the ultimate energy tower." Dr. Lin's projection descended from the top of the tower, and Xiaoman's electronic ripples suddenly reversed control of the tower. As Regulus stabbed into the core, the entire tower turned into particles of light and merged into Xiaoman.
The community returns to calm, but Xiao Man's pupils turn into mechanical compound eyes. Su Wanqing finds a new origami boat in her daughter's school bag, and the sail reads "Game 4: Human Tower Unity". Chu Yun discovers that the purification vehicle has begun to modify itself, and Dr. Shen's medical kit grows metal roots.
Late at night, Xiao Man sleepwalks to the river beach and reaches out his hand to the starry sky. All the meteorites turn at the same time and gather into a miniature planet in her palm - Dr. Lin's smile is clearly visible on the surface.
