Warriors fight dragons, how to upgrade stone houses?

Destroy the room door and upgrade the stronghold.

According to Ranger.com's inquiry, the experience will be degraded after the room is destroyed, but the experience will not be degraded after the stronghold is upgraded. At this time, as long as the doors of all rooms are destroyed during the installation, experience will be added again, so that the stone house can be upgraded quickly after each stronghold upgrade.

The Dragon Fight Series is an electronic role-playing game developed by Ennix (now Ennix, scovill).
