The Time Ruins Key! Upgrade The Gate of Summoning!

Zhou Zhou opened the Supreme Treasure Chest.

There was a green bronze key quietly placed inside.

An item information notification appeared.

[Treasure Name: Time Ruins Key]

[Treasure Grade: Green Bronze-Tier]

[Treasure Effect: Use the Time Ruins Key in an open space in the territory. You can activate a Green Bronze-Tier historical battle— The Time Ruins of the Defence of Indre!]

[Treasure Description: The source of the Time Ruins is unknown. When living beings participate in the Time Ruins and complete the Time Missions within, they can obtain the gift of time.]

[Note: This Time Ruins is an equipment-producing ruin. There is a high chance of producing conventional equipment (Black Iron-Tier, Green Bronze-Tier) and a small chance of producing the high-level soldier recruitment book— Elemental Archer Recruitment Book. There is a very small chance of producing a Hero Inheritance Secret Manual.]

Zhou Zhou raised his eyebrows.
