"Item update: An investigation by a veteran investigator has revealed that items deposited in this item do not disappear, but are sent into the future. Effective immediately, this item has been raised from level six to level one. Its new name is pending."
That was the winding journey of the little green mailbox, from an overlooked level-six object to a level-one object that required confidentiality.
"Over ten thousand tests... This mailbox has sent far too many letters into the future." Ke Meng was speechless.
There was no mention of side effects. After all, many level-six objects had very mild side effects, and some items had none at all.
But seeing that this thing could send things into the future, Ke Meng felt there had to be a price. People simply had not noticed it.
"I need to find out that mailbox's side effects in person. Make the arrangements."
Ke Meng spoke after leaving the house.
Luo Yuan nodded. He would contact his superiors shortly.
For now, there was nothing new to discover in this house.
The door was closed, and Ke Meng could not find where it was either.
"So, what next?" Luo Yuan asked.
"There's an invisible door in this house. It should be a conceptual item, with no physical form. It might be the thing that gave rise to the special field."
"A conceptual item?" Luo Yuan had never heard of that. It was a term Ke Meng had just coined.
"If we can't move it away, doesn't that mean this field will stay open forever?" Luo Yuan frowned. He was starting to get a headache too. He had not expected this to be so troublesome.
He had originally thought they could move the special item away once they found it. Now, things were nowhere near that simple.
