Creating copies of one existence wasn't exactly an easy matter, especially for laws as troublesome as Noah's ambition. He believed himself to be far more dangerous than the rulers, so he couldn't allow for two versions of him to exist at the same time.
Still, Noah couldn't even hold back from making the copies accurate since that would only give unclear results. His issue forced him to change the training area and request other materials to make sure that everything remained under his control.
Copying himself wasn't the main issue. Noah had access to the dark matter, which could become everything he needed it to be. Forcing his higher energy to replicate his existence ended up relatively easy since that fuel was a core part of his law. The problems came later when his creations gained his mind.
"So," A small humanoid figure surrounded by countless inscriptions announced, "I'm not Noah Noah. You are the real Noah, and you have created me to improve yourself."
