Three Kingdoms: From the Start, Cao Cao Wanted to Borrow My Head

After transmigrating to the Three Kingdoms, Jiang Yun became the official in charge of the grain warehouse in Cao Cao's army. From the start, Cao Cao ordered him to distribute grain using undersized measures, hoping to use his head to deliver that famous line of his: "I'll take care of your wife and children. You needn't worry." Fortunately, Jiang Yun awakened the God-Tier Craftsman System. The hundred thousand defenders: Cao Cao has a genius on his side! The siege engines he built can even carry warhorses up onto the city walls. How are we supposed to defend this place? Lu Bu: Good grief! Jiang Yun's forged saber snapped my Fangtian Huaji halberd in a single blow. There's no way we can fight this battle! Zhou Yu: My lord, something terrible has happened. The warships Jiang Yun built won't catch fire! Our plan to burn the enemy at Red Cliffs has gone up in smoke! Zhuge Liang: Jiang Yun is not only a master craftsman, but a brilliant seer as well. I cannot compare to him. If my lord wishes to achieve great things, he must have this man at his side!
