Iron Blood Restart: the Lone Eagle Screams Taihang

Friends, the setting of this book is this - Qi Tongwei wakes up after committing suicide and finds that he has become Li Yunlong and is fighting the Japanese in Cangyun Ridge. I originally thought it was an ordinary time travel and rebirth, using modern knowledge to beat the Japanese, and it would be a blast. As a result, he discovered: strange words like "prism" and "experimental subject" were written in the diary he captured; in the captured photos, there were people who should have appeared in 2026; only he could see the blue light falling from the sky on the battlefield; the Japanese prisoner who was interrogating suddenly asked him in Han Dong dialect, "Why is Director Qi here?"... Only then did he realize: he did not travel through time alone. That thing called "Butterfly Project" brought more people into this era. It's just that everyone's identity has been disrupted - some became the Eighth Route Army, some became the puppet army, and some were in the Shanxi-Sui Army. What's even more terrifying is that the Japanese Army Major Kazuki Yamamoto is actually a time traveler, coming from the Japanese Police Department in 1997. Two time travelers met in this era. Friend or enemy? Who is the chess player and who is the chess piece? What did the person in that photo want to tell him? What Qi Tongwei wants to fight is not only a war of resistance against Japan, but also a war in time and space that spans more than eighty years. Volume 1 has been completed, totaling 10 volumes. Follow-up guarantee: Original characters appear one after another (Hou Liangping, Gao Yuliang, Zhao Donglai... They are all in this era, but their identities have changed) Full of suspense threads (photos, diary, Blu-ray, Gear Butterfly, new clues in every chapter)
