"I enjoyed my last night's sleep yesterday." Kayden didn't say anything else, he had already decided: that sleeping was eating up a lot of time in his day, so he looked for a way to solve this problem.
What he found was a forbidden surgery of placing a small mana stone along with a spell inside his head. This would prevent you from sleeping and would not harm any part of your life.
Your growth as a teenager would not be hindered, your information storage process would not be hindered. It was pretty much just earnings. Even the risk of him receiving a blow to the head did not exist, as the spell would simply dissipate and then return using the stone's mana.
This was a medical miracle when discovered. The person who developed it was currently called the god of medicine and enjoyed a free pass to enter every country on the globe.
