Yeah I already found that spoiler on baidu. It seems to be a rehash of spoiler #3, except in Chinese.
Watch this post for a Spoiler #4 translation.
EDIT: aaand...!
TRANSLATION!CLAYMORE
Following behind Helen and Deneve is Dietrich.
From seven years ago, there has been a so-called devil residing in the southern lands.
Half a town was obliterated; it is better not to go there, they were advised.
Such a target, Riful's normal, outstanding youki* is at the town before my eyes.
They guessed that Isley is probably with the devil. The two leave Dietrich behind.
Coming just to take a look, the two erase their youkis and sneak in.
The two pass by a person looking like Isley, and ended by being exposed.
Relieved for a moment, Deneve potentially kills.**
On that path, hidden in the trees, someone let something out*** - Dietrich.
Isley? Aside from that, the devil approaches the village.
To be continued in the February issue.
*It sounds like Riful's youki is suppressed to AB level.
**This part gets sorta fuzzy. Either Deneve gets killed or she potentially kills. Either way, it implies the use of a blade.
***Meaning, someone did something to get themselves detected.
