Meet Hugh Darrow's contact
Meet Mengyao on the rooftops, she gives Jensen the next quest Corporate Warfare.

Introduction
This side quest is automatically given to you via the Infolink by Hugh Darrow on your second trip to Hengsha, as soon as you enter the Youzhao district.

Overview
First you meet Mengyao in Youzhao district near Yuanmeng road. You will have a conversation mentioning you as a precious asset and a meeting setup by a Mr. Fei. All choices lead to mission of recovering a datachip from some terrorists, which contains the data regarding Darrow's Panchaea project.

Proceed to Daigong district, and head towards Alice Garden Pods. Head down the stairs to the area with sewer entrance. Knock-out the thugs, but do not kill them, as this will fail the mission. One of the two men by the barrel, identified as Li, has the chip. Return to Mengyao and speak to her. You will have the option to use pheromones if you have the Social Enhancer. She is a beta personality type, so only the charm option is effective.

You will learn a little about the Hyron project being created at Panchaea, and receive a final message and some credits from Darrow shortly after.
