Synopsis: I Upgrade by Rewarding Apprentices

If the enemy comes near while the crane master is working towards the west, turn on the apprentice rebate system. The more the master invests in the apprentices, the bigger the reward. Hey, students, there are no secrets I won't share as your teacher! It's a funny situation! Rewritten: Activate the apprenticeship rebate system if the enemy approaches while the crane master operates towards the west. The master will receive greater rewards based on their investment in the apprentices. My dear disciples, as your teacher, I have no secrets to hide from you! It's quite comical!
