C41 Three Skills

The Thought Acceleration made his thinking process two times faster than before but of course Rem mastered the skill immediately which makes him think 10 times faster. Now he can think for an hour but only a minute will pass in the physical world.

The Hiding Shadow was a great skill for hiding or assassinations since at level 1 he can hide from those who has achieved the 1st Rank. But with Rem mastering the skill, he can hide his presence from those in the 10th Rank.

Lastly, the Regeneration skill makes him able to Regenerate losing limbs from his body. He tried this skill in the Pocket Dimension since he doesn't want to be disturbed from anyone. At level 1, his lost hand will only regrow after half an hour. He then mastered the skill which made his hand regrow for 30 seconds.

This was not all the skills that he has copied since he copied many Intermediate weapon proficiency which made his Weapon Master (Basic) upgraded into Weapon Master (Intermediate).

Rem's slaves also didn't slack off since they all made a huge progress. His two knights are now at the 6th Rank 1st Layer which they can already apply as a Royal Knight in the emperor's castle.
