'Even though I have to give it the level 8 version of my Core Skill, as there are similar Skills in the market, it doesn't have as much value as Overdrive Skill at level 8.' The Slave Harem System thought, completing the transaction as it looked at its reserve of Mental Energy, frowning.
[Mental Energy: 253]
'There isn't much left. It takes 1 Mental Energy just to connect to the Astral Network.' It sighed in worry, 'I should buy anything else I need now.'
All it had bought was the Skill of Overdrive at level 8. And, it was a one-off Skill. Meaning, it was only able to use it once. But in response, it had sold the level 8 version of its Core Skill—Slave Harem.
That meant the Overdrive System was able to use the Slave Harem Skill at the level 8 version without any limitations. So, it was a loss-making transaction. After all, it was spending Mental Energy to gain an expendable ability.
