1950: My Mountains and Rivers

[No system + full-line war + group portrait history] Tactical analyst Lu Chuan accidentally traveled back to 1950. He is not a military king or a military industrial tycoon. He is just a military researcher in peacetime. He understands tactical data but does not understand life and death on the battlefield. He became Lu Changhe, a shivering recruit on the train entering North Korea, holding a booklet in his arms. He thought that with the knowledge of the future, he could become a "prophet" on the battlefield. But he soon discovered that - in Changjin Lake at minus 40 degrees Celsius, it was Tieshan who taught him to pour urine on the gun bolt; in Shangganling where artillery fire was raging, it was Gou Sheng who taught him what "killing one is enough to earn money, killing two to earn one"... From a trembling bystander, he stepped into the depths of the smoke. Drawing tunnel maps, calculating ballistic trajectories, doing logistics, doing epidemic prevention... He grew from a soldier in the Third Company to a staff officer of the Volunteer Army. He met the founding generals, revolutionary heroes and thousands of veterans in history books. He wrote down one name after another - the one who was frozen into an ice sculpture, the one who blocked the bullet hole with his chest, the one who fired the grenade and died with the enemy. Then he almost collapsed. "Xiao Lu, fighting is not about playing cards. Sometimes you lose a round so that the people behind you can learn how to win." Lu Chuan finally understood - he was not here to be the savior. He is here to take the guns from the hands of those veterans, help them live a few more years, and remember for them: the password of this army is not in the arsenal, but in people's hearts.
