Chapter 372: Guan Yu and Qin Qiong

[Monster Name]: Skeleton Tyrant

[Monster Grade]: Legendary

[Monster Level]: Level 46

[Ingredients for Promotion to Legendary Grade]: Flames of Darkness, Commander Bones, Thousand-Year Heart of Darkness, and the Essence of the Undying Heart...

These were the main ingredients Dumby needed in order to advance to Legendary-grade. Gao Peng had already collected three of them, plus a few other miscellaneous items. The only ingredient he was missing right now was the Essence of the Undying Heart.

Judging from their names, these ingredients seemed almost mundane. However, it was an established fact that various elements could be combined to bring out the best in each other.

For instance, one could mix potassium nitrate, sulfur, and charcoal together in fixed proportions to produce one of humanity's most destructive weapons: gunpowder.
