'Additionally, the formation of an Energy Bone takes about ten years with optimal usage of energy. This gives the Nightmen much more time to research Techniques and to learn the Internal Technique they will be using in the future.'
For the next ten years, Nick focused on creating different Internal Techniques.
For now, it was more important to give the Nightmen different ways to advance.
Any knowledge and experience they gathered in this era would save years in the next era.
Yes, Nick had to become an Eternal before the era ended, but there were still a couple of centuries left.

'Everyone should be able to find a fitting Internal Technique.'
For now, Nick left the creation of Abstract and Concrete Techniques to the Nightmen.
Internal Techniques were much more difficult to create since they needed to be usable up to the Ninth Realm.
