I apologize for the double-posting, but I have to announce that the 140th chapter is out.
Spoiler:
There's no much hell-breaking action for this chapter, nonetheless, it focuses on two subjects.
1. Lenalee hears the commotion going within the Order and tries to head to the battlefield where Allen is, but she is both detained and confined along with Lavi inside the medical ward, where Krory rests, by orders of Komui.
I think the reason why Komui has locked up Lenalee inside the medical ward is to prevent her from entering the lab where the fight is taking place, because he fears that she would lose her life if she invocates her Innocence, heeding Hevlaska's warning in the previous chapter.
2. Allen and Bookman are alone fighting all the horde of Lv. 3's. Allen has invoked his 'Crown Clown' Innocence to its claymore-sword form.
