Christian worked steadily for a few hours, hands moving automatically, focus unwavering — until finally, he stopped and leaned back.
It was time for a short break.
He checked the time and date — and then it hit him. He had been asleep for three days straight. That meant it was time to collect his Idle accumulation.
And while he was at it, it was also time to finally assign all of his Idle slots into the Lie Detection skill.
After all, he had already developed the mini nuclear reactor. There was no longer any need to continue researching the General Mechanic skill. At least, that's what he thought…
Until a message window appeared in front of him — one he hadn't noticed before.
It wasn't just the usual messaged windows.
He had gained a new passive skill from the Idle System!
Concentration Skill.
Christian's eyes lit up as he saw the notification, and he hurriedly opened its description.
[Concentration (Passive) Lv.-]
