Black Soil and Wild Waves

[Time travel + military + cool writing + passionate war + beautiful agent] Gao Zhiqiang, the king of special forces in the 21st century, died heroically while performing his mission. He actually traveled to the Northeast in 1920 and became an unknown soldier! Peak at the start? No, the beginning is hell! Living in troubled times when warlords were fighting and Japanese invaders were lurking around, he fought his way out of the martial arts hall with his military qualities that transcended the times and became Zhang Zuolin's most valued young marshal. Form the Eighth Division, be promoted to Lieutenant General, take charge of the Rehe Warlord... Power? Beauty? He wants them all! Wait, there's something wrong with this beautiful teacher! Ma Yezhi appears to be a gentle and pleasant Chinese language teacher, but in fact he is a top agent deployed by the military commander! I approached him just to gather information, but I didn't expect - "Report to the stationmaster, I was incited by the target to rebel, and now I only send information to him alone!" When the September 18th Incident broke out, can history be rewritten? When the Marshal ordered "no resistance" and the Northeastern Army retreated steadily, Gao Zhiqiang roared: "I won't serve you anymore!" He led his troops in a bloody battle at Jiangqiao, overwhelming the elite Japanese army with 30,000 men, and killing Japanese corpses everywhere! Retreat to the grassland? No, this is the place where dragons rise! Use black technology to crush and create the strongest iron army! Type 36 semi-automatic rifles, Type 39 howitzers, armored brigades, cavalry divisions... While other armies are still using Hanyang-made weapons, all of his troops have been equipped with automatic firepower! Daqing Oilfield, Steel Factory, Donghua Bank... What he built was not an army, but an industrial empire! Spy war, who is the undercover? Military reunification agents, Japanese agents, traitors and moles... Ma Yezhi takes charge of the Intelligence Department and plays "Mr. And Mrs. Smith" with him...
