My Brother, Li Yunlong, Shows His Sword and Starts the Battle with Katyusha.

In 2026, Li Yuntian, a hardcore World War II military fan, accidentally traveled to the world of swords and became Li Yunlong's brother! At the time of the bloody battle at Cangyunling in 1940, the new regiment ran out of ammunition and food, and the Sakata regiment pressed forward step by step. At the moment of life and death, Li Yuntian awakens to the "World War II Soviet Army's Deep System"! "Brother, don't panic, I brought you some souvenirs!" As a result, the style of painting in northwest Shanxi completely changed. DP-28 Crossfire Network? Katyusha rocket launcher? When the T-34 tank cluster surged in the Taihang Mountains, and when the Soviet three-dimensional air defense position tore the Japanese bombers into pieces... Jun Tada collapsed when he saw the battle report: "Baga! This is definitely Lucia's secret passage!" Li Yunlong grinned: "Brigade commander, my brother said that Comrade Dalinzi is supporting you, so feel free to take it!" Li Yuntian: "To fight the Japanese, we must use the torrent of steel to teach them how to behave!" This novel and its characters are purely fictitious.
