Soldier Assault: He Chenghua Era

In 2025, Lin Yan, a researcher at the Military Research Institute, traveled to the Army Military Academy in 1994 due to an experimental accident, and unexpectedly found himself in the world of "Soldier Assault". From the shock of confirming the designation of the "702nd Regiment" to the firm determination to rush to the 7th Steel Company, he embarked on a journey to promote the transformation of a traditional infantry company into a modern combined force with the military understanding of 2025.​ When he first joined the 7th Steel Company, Lin Yan broke the 3,000-meter running record and shot all over the place, breaking the suspicion that "military students have a good eye but a weak hand". With his precise analysis of tactical shortcomings, he won the opportunity to be given a "one-month trial" by company commander Gao Cheng. While spending time with comrades such as Shi Jin, Wu Liuyi, and Xu Sanduo, he integrated into the group and helped Xu Sanduo adapt to training while quietly sowing the seeds of synthesis: from proposing a "group detour + fire containment" plan to help the 7th Company defeat the 2nd Company, to writing the "Preliminary Plan for the Construction of Synthetic Forces" and using the Gulf War case to convince the military to list the 7th Steel Company as a pilot.
