The filming was nearing its end, with only two scenes left. This part described Zheng Huayu crazily taking revenge on the robot, but the robot had superpowers, so Zheng Huayu couldn't do anything to it for the moment.
Later, he thought of the only way, which was to deceive the heroine to come to the appointment, and he planted a bomb in the building, intending to blast the robot to smithereens.
The bomb exploded but failed to hit the robot, causing the building to collapse. The robot, in order to protect the heroine, pushed her out.
Actually, the robot could have escaped with the heroine and didn't need to die.
But Zheng Huayu was also trapped in the building, about to die. The robot finally let go of the heroine and turned back to save Zheng Huayu.
After rescuing Zheng Huayu, the collapse of the building became more violent. Zheng Huayu pulled the heroine to escape, but a large stone fell and was about to hit the heroine.
