Brothers Li Yunlong and Li Aiguo live an ordinary life full of dreams in modern times. They grew up with their grandparents, and their parents worked outside all year round. Although the family was not complete, their grandfather's story of the Anti-Japanese War was deeply imprinted in their hearts.
By accident, the brothers traveled back in time to the war-torn era of 1940. Li Yunlong woke up and found himself in the New Regiment camp, while Li Aiguo was at Yenching University. What's even more amazing is that Li Yunlong has a modern military command and operations book next to him, and Li Aiguo also has military merit textbooks and a history book.
In Xinyi Tuan, Li Yunlong struggled to adapt to this strange yet familiar environment. He relied on the military knowledge he had learned in modern times to try to change the situation of the war, but he also faced many challenges from both internal and external sources. The soldiers were confused by the novel ideas he sometimes showed, and the strength of the enemy army also made him feel stressed.
On the other hand, Li Aiguo was not having an easy time at Yenching University. He has to deal with the curiosity and doubts of his classmates, and also find ways to find the whereabouts of his brother. In the process, he met his cousin Zhao Gang, and with Zhao Gang's help, he gradually integrated into this era.
The two brothers struggled to move forward in their respective predicaments, always carrying in their hearts the longing for their modern family members and the confusion about the future. Can they stand firm in this turbulent era and use modern knowledge and courage to create miracles? Can they find each other and jointly write a legend of the Anti-Japanese War that belongs to them? All the unknowns are waiting for you to uncover. Follow the footsteps of the two brothers and enter that magnificent history.
