In the game, in addition to displaying more cultural relics, you can also increase your popularity by upgrading existing cultural relics. Each cultural relic starts with one star and can be upgraded to a maximum of five stars.

The resources required to upgrade cultural relics to stars include currency and tool spirits. The type of currency consumed is determined by the rarity of the cultural relics. Among them, vegetation and mountain cultural relics consume flowers and tool spirits, sun, moon, heaven and earth cultural relics consume diamonds and tool spirits, and star cultural relics consume Some consume flowers and weapon spirits, and some consume diamonds and weapon spirits.

However, comparing the cost of star upgrades and the increase in popularity value of cultural relics of different rarities, it can be seen that the higher the rarity of cultural relics, the more cost-effective it is to upgrade stars. For example, if the heaven and earth cultural relics are upgraded from one star to two stars, 2440 tool spirits will be consumed, and the popularity value will be increased by 76; while the sun and moon cultural relics will be upgraded from one star to two stars, 1560 tool spirits will be consumed, and the popularity value will be increased by 56.

Therefore, curators can accumulate as many artifact spirits as possible to increase the popularity of high-rare cultural relics.
