[Mission: Obtain the Key to the Door ] [Reward: Neurolink Overload]

'A mission?' I was suddenly jolted by the sound of the mission notification. 

After reading the content, I recalled the door inside that dark space. I did feel something when I saw that door. It was like it was calling out to me. Unfortunately, I could not open it no matter what I did.

'Neurolink Overload?' That term made me curious. Just from that name, I could tell that it was a massive power-up. However, 'overload' suggests exceeding capacity, so it might be a very strong skill with a penalty after using it.

Regardless, I doubted that a skill from a mission would be weak. In fact, this was the first time the system gave a skill as a mission reward.

But the issue now revolved around the key. The system had just informed me that there was a key, but where and how could I find it?
