Leader Liangjian, Don't Make Mistakes

In the world of "Bright Sword", the flames of war are raging again, and people are risking their lives to fight against foreign enemies. Qin Nantian accidentally traveled to Cangyun Ridge and faced a helpless reality - his system required blood extraction in exchange for magical skills. Although he was full of frustration, he could only temporarily succumb to this system, hoping to one day be able to compete with it. Qin Nantian was patriotic and started doing business to provide Li Yunlong with the supplies he needed. Although he didn't know whether these transactions were losses or profits, he still did his best. He said to Li Yunlong: "Brother Yunlong, you use these weapons first, and do it yourself wherever you need improvement. Don't worry, we have resources from sea to land to air, I'm afraid you won't use them. As long as you don't make mistakes, everything is possible in the future!"
