Idle Miner Tycoon: New Event Mine Finished Under 10 Minutes!

Hello, everyone!
Today, I will show you how I completed the newest weekly event mine (Eco City Mine) in only 8 minutes without Sir Lorenzo, Samantha Reiss, Violet Evergreen, and Octavia De Vere which I usually used them to boost the mine. (FYI: This video doesn't have an actual purpose to be a tutorial video.)
Well, actually I don't really like the update; when we reached a shaft that containing some rewards, it just immadiately claimed in the middle of the run. It's really annoying because it can ruins our run/speedrun. Even though (in my opinion), they've did the correct thing in the past; rewards from event mine can be claimed at the end of the event! I saw some players which usually finished the event mine in only 2-3 minutes, they now can only finished it in 3-5 minutes. Well... this thing is actually not really important, but when players get new their records, it's just pretty cool and satisfying to see.
About what I said above like "I'm sure I can finish this (event) in under 5 minutes." is actually true. I just need some strategies about setting the super managers, upgrading steps, fast tap, and especially "focus". I'm sure by this, I can finish the event mine faster than this.
I think that's all for today. I hope you all enjoy my videos. Thanks for watching!
