In the Otherworld, things like upgrades often come at unpredictable moments.
Take right now, for instance; Lin Yue never expected that after building a medium-sized food preservation cold storage next to a small food processing plant, he would receive a system notification about an "upgrade."
"Oh wow, an Intermediate Universal Upgrade Design Map can merge these two together and directly upgrade to a large integrated factory—how cool is that?"
Normally, he uses the Universal Upgrade Design Map to upgrade weapons or machine dogs.
Now, to suddenly be able to use it for factory upgrades was definitely beyond his expectations.
Who would've thought that buildings could be upgraded together?
"An Intermediate Universal Upgrade Design Map... I still have ten of these, which is quite a lot. If this thing ranks first in the group next time, I suppose I'll get another one."
Lin Yue muttered to himself, wiping the sweat off his forehead.
Why is it so hot today?
