In 2026, the Earth's environment deteriorated, plunging humanity into a major ecological crisis. Relevant departments such as the Forestry Bureau and the Ministry of Land and Resources attached great importance to the situation. Leaders and cadres actively responded to the crisis. Following instructions from higher authorities, the Environmental Protection Base decided to select a group of outstanding members to form the Steel Dragon Environmental Protection Team, tasked with investigating the causes of the Earth's environmental crisis and finding ways to prevent further deterioration. The team consisted of five young individuals: Captain Blaze, strategist Deep Blue, athletic expert A-Tai, young girl Xiao Xin, and computer genius Xiao Xing. Through countless hardships and dangers, they thwarted the schemes of the mastermind behind the crisis—the evil scientist "Demon Lord"—and restored the ecological environment to normal. The Earth returned to its former peace, and the Steel Dragon Environmental Protection Team members returned to their base, continuing their efforts to protect the Earth's ecological environment.
