Verification

Verification (検証, Kenshõ) is the 2nd chapter of Volume nine and 72nd chapter overall.

Plot
The investigation team decides to go along with Kira’s plan to retrieve the notebook. Light asks Ryuk if he can convince Jack Neylon’s shinigami to do nothing while they retrieve his Death Note. The investigation team will go in fully equipped with cameras on the shield helmets so that Light can see what exactly what they see.

On November 10th at 11: 47 p.m., the investigation team is in place and ready to ambush Mello’s hideout. Light gives Ryuk orders to find the other shinigami, convince him to stay away and promise him that by doing so, he will get his notebook back. When Ryuk finishes talking to Sidoh, Soichiro gives the go-ahead to trade half of his lifespan for the shinigami eyes. He looks at the photographs of the subjects and can see their names and lifespans. At 11: 59 p.m., the names and lifespans of the subjects disappear. This is the signal to move in and launch the attack.

Conception
Ohba said the chapter's title "Verification" is about the checking and the verification of the battle plans that happen before the raid in the chapter. It mainly applies to the last two pages in the chapter.
