Bright Sword: From the Start, I Summon My Good Brother Shunliu

Li Yi inexplicably finds himself in a mash-up world of the War of Resistance. From the start, he catches Japanese soldiers bullying an innocent woman. One swing of a brick kills a Japanese soldier, and he unexpectedly obtains the Good Brothers System. Killing Japanese soldiers and bandits earns him battle merits, which he can use to summon all kinds of good brothers. With a chicken stuffed inside a chicken and a sniper rifle, Li Yi summons the good brother Shunliu from the start. Then Wei Guo, Xiao Zhuang, Chen Guang, the Shuang Ying brothers, the Old Lady with Two Guns, Da Dao Wang Wu, Master Jiu Zhang San, Ge Erdan, Little Soldier Zhang Ga, and a whole host of other good brothers make their entrance. I've got just a few hundred million good brothers, enough to chop the Japanese soldiers' heads right off.
