As Zhang Tie was the Weiji General of the Western Theater of Operations of Taixia Country, even Zhang Yang should call him general in the headquarters instead of calling him younger brother.
Of course, Zhang Tie understood it too. After throwing a glance at Zhang Tie, he instantly noted, "Now that you're all clear that you're fetched here for tasks, I will put it straight. As I'm in charge of the logistics affairs in Huanzhou Province, Kangzhou Province, Ningzhou Province and Military Province, I've got an all-around plan within these days. I need your help. The following issues were to be solved: first, the insufficiency of all-purpose medicaments in the theater of operations; second, the production of Fiery Oil; third, the training of air forces in the theater of operations; fourth, the provision of armed equipments driven by Fiery Oil; fifth, the grains production in the theater of operations. If we could solve the 5 issues, I will never regret being Weiji General."
