Control your smartphone and select "Dominant Domain Creation".

　Hmm?

　An unfamiliar item was added to the smartphone.

　-- [Extended]

　Expansion?　Is the area of control going to be larger?

　If all the demon kings expand and their dominion area expands, the human race will be extinct in no time, right?

　I tap [Expand] to try it out.

'Do you want to expand the dominant area?　YES NO

　Hmm?　There's no CP or DP consumption listed.......is it free?

　I tap 'Yes' for now.

'Error. You need to eliminate all intruders before you can expand.

　Huh.

　Come to think of it, I'd left it to my subordinates, but my dominion territory was in the midst of an invasion from humanity.

　I took control of my smart phone and observed the intruders in real time.

　They'll be retreating in about an hour?

　Should we send in our elite troops early this time?

　I gave the order to my men and waited for the intruders to retreat.


　An hour later.

　The elite force took out four humans, a little more than planned, and the remaining eight retreated.

　The invasion was two hours ago, so I have four hours to spare.

　I once again operated my smartphone and tapped 【Expansion】, continuing to select 'YES'

　--!

　An earthquake!

　The ground shook, and the landscape around me shuddered.

　After a minute or so, the shaking stopped.

　I operated my smartphone again.

　There's no earthquake bulletin.

　If that's the case, then the shaking I just saw is a phenomenon caused by - 【Expansion】.

　I tap 【Dominant Area】 and confirm the result of 【Expansion】.

　--!

　More layers?

　There are two words that are unfamiliar to me in the information displayed. Hierarchy and stairs.

　My area of control has been extended to two levels.

　The newly expanded second level (the first basement level) was a rather large space with nothing set up, as far as the map shows.

　That's only an increase in the maximum DP of 10.

　For now, let's create a corridor and a small room to get it in shape.

　DP only increases by 10.......when are we going to accumulate a DP of 1000?

　Hm?　Could it be...?

　I realized a possibility, and took control of my smartphone.

　--!

　Yes!　Until now, only two 【Resting Place】 locations could be set up, but it was possible to set up one 【Resting Place】 at the new level as well, although it was only one location. With this, he secured a DP +50. Furthermore, 4 more treasure chests could be installed, giving him a DP+4.

　Other types of equipment and traps had also increased due to the growth of [Creation].

　I placed the staircase to the far end of the first layer, preparing a system that would prevent intruders from entering the second layer, and spent the small amount of time it took for the next intruder to arrive to create the dominant area.

　Eighteen hours later.

　After three interruptions of human invasion, the second layer had been completed.
