Sky City? Sammi told me to post it

An unprofessional guide of 136 hours and 34 minutes. Cleared the fourth campus. Since many people are playing the dungeon for the first time, Sammi would have asked me to post a guide every day otherwise. For the monster invasion at the top left of the fourth picture, you can consider watching ads for the most money. Student interaction is less frequent. You can get magic stones from the daily report. If you're short on them early on, consider it. It's needed for upgrading holy water, fruit trees, and drawing professors. The limited-time campus at the top right has resources, but magic pets require a lot of time and have low efficiency, so you can skip it. The fifth picture shows the upgrade resources for holy water. Holy water production can be upgraded to level 20, which greatly affects offline earnings. My maximum offline time in the first picture was 3 hours, and watching ads gives 3x earnings. I'll explain later how to play without spending much time, which affects offline earnings. The second picture shows the advanced wizards of the first three campuses. Breakthroughs with fruits are needed every 10 levels. Among the six students in the first campus, the latter three have higher combat power. The fruit tree in the sixth picture goes up to level 5. The seventh picture shows other branch campuses, which open when honor and combat power reach the target. Once opened, you directly enter new campuses and occasionally return to old ones to collect rewards and level up. The gift shop campus is calculated separately. The third picture is adventure. You can send them out on adventures to get rewards. Training opens at the fifth stage. Each level up allows simultaneous training and adventuring. You might get blue fire, which can be used for upgrades below the classroom. For gameplay with offline earnings, through unprofessional testing, due to student walking time, study time, and flow issues, offline earnings might be higher than idling online (online earnings are higher in the shop). So, collect 2x earnings every 30 minutes, along with other resources for upgrades, saving a lot of time. Can't finish writing in 500 characters.
