Heaven Underworld
Lin Sanjiu infiltrated the Munitions Factory to investigate who sent Tunnel, Lollipop, Flame Arm, and Ikkaku after her. She passed by Levin while entering the building disguised as a middle-aged man. He was on his way outside after closing other entrances to see if anyone had seen a strange woman in this one, but upon realizing that the duoluozhong in the nature reservation reacted differently to her than it should to a middle-aged man, he found her to be suspicious and began searching for her inside the factory.

Catching sight of her just as her male mask's time limit was wearing off, he gave chase and ordered the other factory workers to help too. When cornering her into hiding, he sent the other workers away and tricked her into showing herself by using a method to make her hear Meowie Hu and Puppeteer's voices. Upon realizing it was a trap, she bolted again and hid in a sweatshop. Levin rallied the factory workers to look for her, but the effort was interrupted by the arrival of the security department, led by Silvan, who was also an acquaintance of Lin Sanjiu's.

The two heads got in an argument about who had the jurisdiction to catch the infiltrator a.k.a Lin Sanjiu, while the rest of the crowd gossiped about their rivalry. In the end, Silvan won but not before Levin gave him a false description of Lin Sanjiu's appearance. However, Silvan was not tricked, and after doing his own quick investigation using the "A Detailed Guide to Forensic Reconstruction of Dinosaur Fossils" Book he attained from Kisaragi Library, he ascertained that the perpetrator was Lin Sanjiu and helped her escape the factory from under Levin's nose.

When Lin Sanjiu asked Silvan why Levin was chasing her, he told her that as the captain of the combat department, he received commissions for assassinations, so most likely, he was hunting her down on someone else's behalf. He also explained how he used to be the captain of the combat department first but got transferred to the security department by the higher-ups while Levin was promoted to his old position. He speculated that the higher-ups did it on purpose so that they would keep each other in check. He had done his own investigation on Levin's background but came up with absolutely nothing; it appeared as if the man had popped into existence out of nowhere one day.
