Formations could be controlled by the formation key. There would always be a master key that would have the highest level of authority. For a 1 Star formation, there would be 1 rank 1 key that could also control the formation which Eric gave to Davor in case something happened.
This would greatly increase the safety of the store and the auction house. Don't look at the formation being only a 1-star high rank. That was enough to block attacks from everyone below the Foundation realm for a while. It could even take a few hits from a foundation realm cultivator.
Eric also needed to come up with ways to earn money from formation masters. The formations were great, but to make them, the formation master needed to go where they needed to be built. Eric didn't want to start sending them off to other places.
Eric got Davor to close the store and get someone to build a second floor with some small rooms for cultivation.
A couple of days passed by until the second floor got added. It would have taken a lot longer, but with so much money provided, there were a lot of people who got hired, so the task was done quickly.
Eric got the formation masters to start creating Qi-gathering formations of different levels. There were 10 different rooms since it was made for cultivation and didn't need to be big.
The formation masters made 4 low-ranked formations. Another 4 medium-ranked formations, and 2 high-ranked formations.
The high-ranked formations would cost more, but there wouldn't be as many people who had the money to use them, so Eric didn't make a lot of room for that.
