One day, a huge crack suddenly appeared in the air of the city, followed by mechanical monsters attacking the city. The passionate young man Le Tianxiang, who wanted to be a hero, also accidentally became a partner with the explosive mecha Lingkong in this attack, and defeated the enemy with the joint efforts of the two. Since then, mechanical monsters have attacked the city one after another. In the process of fighting against the enemy, Le Tianxiang and Lingkong have also met and become teammates with the honest and warm man Shi Dagang, the little devil Si Xiaosu, and the handsome and elegant Duanmu Hai and their partners. In addition, everyone has discovered some connections between these attackers. There seems to be a more powerful manipulator behind them! Just as everyone was preparing to conduct an in-depth investigation, a mysterious transfer student Fang Falcon who also has an explosive mecha partner came to Le Tianxiang's class. Since Fang Falcon joined the team, the enemy's mechanical monsters seem to always attack everyone's weaknesses, causing the protagonists to make decisions several times. After some investigation, it was discovered that Fang Falcon was actually an undercover placed by the villain next to everyone! Everyone found out the truth and helped Fang Falcon untie the knot in his heart. They also learned from Fang Falcon that the mastermind behind the villain, Thunder Domain Demon, was recovering his power and wanted to obtain the scattered blackened core fragments for revenge on humans! In order to stop the conspiracy of Thunder Domain Demon, everyone, with the help of their fathers and the masters of the explosive mecha, split into two groups and embarked on a journey to collect the blackened core fragments.
