第 25 集: 大茶之水博士與阿童木出席深城開幕，同時應對虛構的環境系統

25

Dr. Ochanomizu and Atom visit the inauguration ceremony of Deep City. Deep City is an ideal city built underground to maintain the environment above ground. However, the city's designer, Dr. Sebastian, realizes that the environmental restoration system, which is essential for this underground city, is a forgery. If the city is allowed to continue operating, the pollution could spread from underground to the entire planet. Mayor Manny built this city for honor, but he couldn't spare the money for the environmental restoration system. Dr. Sebastian, who was locked up by Mayor Manny because he found out about it, sprays Chemical A, a plant growth formula, to stop the city from functioning and becoming a threat to the Earth. Trees start to grow abnormally and become like monsters attacking the city. Atom tries to save the people who are running for their lives, but his efforts are in vain as the trees continue to rampage. Atom must find away to stop the growth of the trees and save the people.
