"The Storm of Explanation and Teaching Under One Person"
Travel through the alien world, take control of Nezha's divine power, follow the path of the Heavenly Master, and uncover the shocking mystery!
Modern young man Lin Feng accidentally traveled to the alien world of "Under One Person" and was given a mysterious "Nezha System" novice gift package. However, because the system was asleep, he was forced to practice the teaching method with low-level interface with difficulty. In order to awaken the system, he must challenge the pinnacle of the alien world - Zhang Zhiwei, the old master of Longhu Mountain.
When he first came to another world, Lin Feng was involved in the chaos of the whole world. With the power of the temporarily summoned Nezha Dharma, he averted the danger and formed an indissoluble bond with Lu Linglong, Feng Baobao, Zhang Chulan and others. From the fierce battle at Luotian Dajiao to the exploration of mysterious ruins, from the cracking of the evil sect's conspiracy to the pursuit of the secrets of the Jiashen Rebellion, Lin Feng gradually uncovered the shocking truth behind the system as he grew up - which is closely connected with the history of the alien world, the origin of the Eight Wonders and even the mystery of his own time travel.
At the same time, his relationship with Lu Linglong quietly grew during the life-and-death adventure, but was plagued by twists and turns due to Lu Jin's concerns and power competition. Faced with the entanglement of Quan Xing, Shi Lao, and the mysterious organization, Lin Feng must integrate the teachings of Taoism and Nezha's divine power to completely change the fate of the alien world on the road to protecting his companions and pursuing the truth.
