MiHoYo

A handy steel sword which contains scissors, a magnifying glass, tinder, and other useful items in its sheath.

A catalyst carved out of the hard jade from Jueyun Karst north of Liyue. Small, light, and durable, it is known more colloquially as the "jade ball."

A cheap fantasy novel with no value whatsoever. Any claim that it possesses the power of catalysis is also pure fantasy.

It is said that this bow can shoot down eagles in flight, but ultimately how true that is depends on the skill of the archer.

A reliable steel-forged weapon that serves as a testament to the great adventures of its old master.
