Bai Youwei looked at Robert tauntingly, pulling out the two pieces of paper that she had copied down earlier.
"Before the middle-aged woman in room 405 died, your coded message was:
Four · 囨 return · 囨 囬 group · Four 孩 囨 因 囬 group park,
囡 · Four 孩 囤 囤 · Picture return trapped · 固 团 surrounded by return · 图 囝 Circled group,
As long as you substitute these words for four zero five, this coded message becomes-
Four · 囨o · 囨 囬e · Fouri 囨 因 囬e park,
囡 · Four 囤 囤 · four · zero · five,
At first glance, it still doesn't make much sense, but the second part of the 'four 囤 囤' got me thinking. This is a four-letter word, the second word is i, and the last two words are the same. Considering the experience of the guest 405, it's not hard to guess that the word is 'kill'. Hence, I know that 'four' is k and that '囤' is l. Substitute these back into the coded message and it transforms into-
k · 囨o · 囨 囬e · ki 囨 因 囬e park,
