Chapter Summaries

Lin Li rallied Cisco and Caitlin to help Harry rescue his daughter from ZOOM, then visited Christina McGee at Mercury Labs with a mysterious blue USB. Christina remained suspicious after security escorted Lin Li out, but his promise that the device could make Mercury Labs the world's top technological laboratory lingered with her.

• Lin Li explained that ZOOM had kidnapped Harry's daughter, and Cisco and Caitlin agreed that Team Flash had to help Harry.
• Cisco worked with Harry to locate Central City's breach wormholes while Caitlin retrieved Jay's examination records at Lin Li's request.
• Lin Li went to Mercury Labs and barged into Christina McGee's office after the receptionist refused to let him in without an appointment.
• Lin Li placed a blue USB on Christina's desk and claimed it would help Mercury Labs become the world's top technological laboratory.
• Mercury Labs security escorted Lin Li out, and Christina watched him leave while considering his claim about the USB.

Lin Li helped Harry identify the energy needed to sustain the breach and urged him to rest while the team prepared to locate the other breach wormholes and rescue his daughter. At Mercury Labs, Christina McGee noticed the USB Lin Li had left and recalled his promise that it could help her laboratory become a world leader.

• Lin Li left Mercury Labs after being escorted out, confident Christina McGee would examine the information on the USB.
• Harry told Lin Li, Cisco, and Caitlin that Interdimensional Energy could help them detect breach wormholes using STAR Labs' satellite.
• Lin Li stopped the exhausted Harry from helping Cisco and sent him to rest with Caitlin.
• Lin Li ignored a call from an unfamiliar number and headed to Cisco's laboratory to work on the satellite detection setup and other preparations.
• Christina McGee reflected on Mercury Labs' slow progress and saw the blue USB Lin Li had left on her desk.

Christina McGee opened Lin Li’s flash drive and discovered that it contained Mercury Labs’ stolen research as well as extensive solutions that could advance her work. The document ended just before the crucial final details, leaving her furious and desperate for more.

• Christina McGee isolated her computer, then opened the flash drive and found two folders containing research topics central to Mercury Labs.
• Christina McGee read the first document and realized it matched her research, believing Lin Li had used the stolen work to threaten her and endanger Mercury Labs.
• Christina McGee discovered that the document continued far beyond the point where her own research had stalled, and she eagerly read the new explanations.
• Christina McGee recognized that the document offered major breakthroughs in energy conversion and storage, becoming increasingly excited as she read.
• Christina McGee reached the end of the document before it revealed the final crucial details and erupted in frustration at Lin Li.

After discovering the extraordinary research in Lin Li’s USB, Christina McGee learned he was connected to STAR Labs and urgently called him to secure his cooperation with Mercury Labs. Lin Li rejected her call, so Christina set off for STAR Labs to find him in person.

• Christina McGee read Lin Li’s research papers and ordered her staff to identify him after learning he had already left Mercury Labs.
• The computer department matched Lin Li to STAR Labs and found his phone number, while Christina dismissed a possible match identifying him as a murderer.
• Christina concluded Lin Li had brought the research to Mercury Labs because STAR Labs could not continue it and feared he might offer it to a competitor.
• Christina called Lin Li to discuss the USB, but he said he had no time and hung up.
• Christina grabbed her bag, took her secretary, and rushed to STAR Labs to pursue Lin Li.

Lin Li and Cisco studied the breach wormhole in STAR Labs and discovered that it rejected objects because its passage between worlds was unstable. While they worked, Caitlin received Christina McGee, who tried to learn about Lin Li and tour the lab but left without meeting him.

• Lin Li and Cisco examined the breach as Caitlin admired it, and Cisco tested it by throwing in his belt and other objects, which it spat back out.
• Lin Li explained that the breach's doors and passage shifted constantly, so they and Cisco recorded its energy fluctuations and surrounding conditions for several hours.
• Caitlin went to the reception room to meet Christina McGee after Lin Li turned off his phone and ignored her calls.
• Christina McGee tried to recruit Lin Li and asked Caitlin for a tour of STAR Labs, but Caitlin refused because the lab was closed for renovations.
• Christina McGee learned that Lin Li would be busy for most of the day and said she would return the next day to discuss cooperation.

Lin Li sent Team Flash to investigate Central City’s breaches, while Harry received a secret signal during his scan route with Cisco. Harry concealed the device and redirected their next stop, leaving the source of the signal unknown.

• Cisco revealed that there were fifty-two breaches across Central City, though some were too unstable to let anything pass through.
• Lin Li assigned Barry and Iris to the east, Caitlin and Joe to the west, Cisco and Harry to the south, and himself to the north.
• The teams took detectors and set out to scan the breaches, each needing at least fifteen minutes of readings to gather data for closing them.
• As Cisco and Harry finished scanning a breach, Harry received a flashing blue signal on a device hidden in his pocket.
• Harry concealed the device, told Cisco he had bumped his hand, and redirected their route to another breach.

Harry learned that ZOOM needed the Speed Force because his speed was destroying his cells, but ZOOM forced him to cooperate by repeatedly taking Jessie hostage. A month later, Lin Li and Harry completed a breach implosion reactor, and Lin Li discovered that his ice cream contained a substance making his cells explosively active.

• Harry confronted ZOOM and explained that STAR Labs' tests showed ZOOM's cells were collapsing from the chemicals that increased his speed.
• ZOOM briefly let Harry reunite with Jessie, then snatched her away again and demanded Harry's help in exchange for her life.
• Harry agreed to help ZOOM, then told Cisco that the breach needed more time while they recorded data.
• Over the next month, Cisco began dating Kendra Saunders, Barry and Patty got together, and Christina McGee kept trying to meet Lin Li.
• Lin Li, Harry, and Cisco developed a breach implosion reactor, though they still needed to manufacture fifty more.
• After eating ice cream, Lin Li sensed a chemical making his cells explosively active, and Shanshan 2.0 transformed into particles and entered his body.

Lin Li discovered that ZOOM had poisoned the ice cream to make him use up his Speed Force, then waited for Harry to choose between betraying STAR Labs and protecting his daughter. Four months later, Christina McGee visited Lin Li and revealed that someone who looked exactly like him lived in the East.

• Shanshan 2.0 found that every ice cream contained a compound that could make Lin Li's cells combust when he used the Speed Force, so Lin Li destroyed that day's portion and continued training.
• Lin Li suspected ZOOM was behind the poisoned ice cream and waited to see whether Harry would cooperate with ZOOM or tell STAR Labs about his daughter's danger.
• Shanshan 2.0 discovered that Harry had accessed Caitlin's computer and downloaded research data about Lin Li and Barry, and Lin Li ordered her to monitor Harry.
• Over the next months, Lin Li helped Harry and Cisco build breach implosion reactors while Barry captured criminals and metahumans brought to the area by ZOOM.
• Christina McGee met Lin Li at STAR Labs and said she might have traveled East to meet someone who looked exactly like him, leaving Lin Li wondering about his double.

Lin Li negotiated a 20% stake in Mercury Labs and access to its researchers and equipment, then asked Cisco to find his doppelgänger. Cisco discovered that the other Lin Li had murdered his girlfriend, who shared Yang Shanshan's name.

• Lin Li demanded that Dr. McGee make a final offer, warning that he could build a competing laboratory if Mercury Labs could not meet his needs.
• Dr. McGee offered Lin Li a 20% stake, a technology security consultant position, and a separate research division with access to Mercury Labs personnel.
• Lin Li accepted and requested researchers studying faster-than-light particles, black holes, and wormholes, with the work to take place in Building Three of STAR Labs.
• Lin Li returned to the control room, where Cisco stopped designing an app to search for Lin Li's doppelgänger in Guangdong Province, Jiangxia City.
• Cisco found that Lin Li's doppelgänger had murdered his girlfriend, Yang Shanshan, and Lin Li dropped his glass of milk.

• Lin Li hacked the hotel's guest records and surveillance footage, identified Constantine as Chas Chandler, and found that he had booked room 027 under that name.
• Lin Li entered Constantine's suite and found him working out, so he yanked him up and punched him in the eye.

Lin Li confronted Constantine over his investigation into the doppelganger murder, then set out to visit the doppelganger before her execution. Chen Luo drove him to the area near Huafu Residential Area, where Lin Li headed toward its back entrance.

• Lin Li interrupted Constantine and demanded results from his investigation, taking his laptop from Constantine’s bag.
• Constantine claimed he had been replenishing his magical energy and decided to call a prostitute after Lin Li left.

• Constantine took a grotesque left hand and white powder from his bag, then gave Lin Li the hand to hold.
• Constantine explained how the Hand of Honor and soul-guiding powder would summon the dead soul, then sprinkled the powder over Shanshan’s corpse.

Constantine attempted to summon Yang Shanshan’s soul from her corpse, briefly causing the world to freeze before the summoning failed. He concluded that Yang Shanshan’s soul had disrupted time, while Lin Li’s scans found nothing unusual about her body, leaving both men unsettled about the forces involved.

• Constantine sprinkled soul-guiding powder over Doppelganger Shanshan’s corpse and used the Hand of Honor to perform a soul-summoning ritual.

• Lin Li summoned Shanshan 2.0 to scan the corpse, which proved to be an ordinary body decayed for five months.
• Constantine warned Lin Li that Yang Shanshan’s soul might bring trouble from Heaven and Hell.

Lin Li learned that Yang Shanshan may have found Constantine's cursed Book of Magic and kept the Skull Cross key so he could seek the book himself. After reaching Chishi Prison, Lin Li left the exhausted Constantine with Chen Luo, whose imagined spy mission led him to take rope from the trunk.

• Lin Li asked Constantine about the crossed-out item in Yang Shanshan's diary, and Constantine explained that the Skull Cross was the key to his ancestor's cursed Book of Magic.
