Engine Heart Zhao Yun (Qiji 78005)

About this set

This Engine Heart Zhao Yun (QMAN 78005) sits in the Honor of Kings series under the mecha category, with a difficulty score of 2/5, so it is a fairly approachable build. The box shows the QMAN brand and the product name Light Factor | Engine Heart. The finished model uses blue, black and gold, and the mecha features a long spear weapon, a pointed helmet, shoulder armor and a backpack, which together carry most of the silhouette. When building, I would assemble the torso and backpack frame first, then add the shoulder armor and helmet, and attach the spear to the hand last, since the shoulder armor and backpack shift the balance of the whole model and reversing the order tends to force rework. It is a static display set rather than a play feature model, and the 2/5 difficulty means shallow part layering, making it a good fit for newer mecha builders who like the Honor of Kings theme, while the officially licensed status matters to collectors who care about source accuracy.
