Qiao Yuxi's heart was suddenly ignited with a tiny flame of hope.
"That canned food was already rotten after so many days since it was opened, so I threw it away. The key is still there, but the gloves were stolen by the mongoose, and I was too lazy to ask them for it back; they're quite fierce to the birds."
Mo Bailin took the key in its beak and handed it to Xu Ying, then led her to where the discarded can was.
Xu Ying opened a specially brought sealed bag and, wearing gloves, placed the two items into the bag.
Mo Bailin was very curious about this operation by Xu Ying, "Can this small bunch of keys and an old can really send that nasty man to jail?"
Xu Ying explained DNA testing to Mo Bailin briefly: "As long as it's something the man touched or used, it will leave DNA. The DNA can prove he has been in the desert, which can prove he's lying."
However, she was unsure if they could still detect DNA on these two objects, they needed more evidence.
