In the past, Cui Junjing's husband was invaded by parasites, and she had to subdue him with her own hands, which became an eternal pain in her heart.Now, after Seol Qiangyou and Zheng Xiuren survived, Xue Qiangyou suggested that Zheng Xiuren and the “Heidi” in her body go to the police and let the police know about the bodies in the church.However, because Jung Soo In's identity cannot be exposed, they can only call the police anonymously.Xue Qiangyou's anger towards the parasitic beast could not be quelled because his sister turned into a monster and his sister was also killed.

After Seol Qiang-woo called Kim Cheol-min, he suggested that Jung Soo-in hide to ensure safety.Kim Chul-min struggled with whether to believe the call to the police, but Detective Kang thought he should report it to the Gray Team first.The Gray Team and the police then headed to the church's stronghold, but the living parasite did not feel any similar brainwaves.Cui Junjing suspected that the living parasitic beast might be lying, so he sent a team to the warehouse.

In the warehouse, they found many broken corpses, which was obviously the canteen of the parasitic beast.Although no parasitic beast was found at the scene, Cui Junjing noticed that Kim Cheol-min put the keys on the ground into his pocket. On this set of keys was a pendant that Kim Cheol-min gave to Jung Soo-in.The Gray Team also learns that the head of the church, Kwon Hyuk-ju, and his wife disappeared a few weeks ago, and that the church people seemed to have only taken away important things.Cui Junjing began to doubt Jin Zhemin's behavior, but she chose to observe silently.

What no one expected was that Detective Jiang was the one who disclosed the information to the church.Detective Jiang expressed his confusion in front of the parasitic beast about the mutual betrayal and killing of similar species.Kwon Hyuk-joo ordered Detective Kang to remove the hounds to ensure that their whereabouts and whereabouts would not be discovered.This task needs to be completed by Detective Jiang, who is a human, in order to avoid arousing human suspicion.

Kim Cheol-min contacted Jung Soo-in hoping to meet, and this move was also controlled by Choi Jun-kyung.Jin Zhemin just wanted to know what happened when Zheng Xiuren went to church. He was worried about Zheng Xiuren's safety, especially because there was an unknown Xue Qiangyou beside her.When Cui Junjing brought the hound to Zheng Xiuren's location, she immediately sensed it.

Cui Junjing pointed his gun at Zheng Xiuren, and Xue Qiangyou quickly escaped with Zheng Xiuren.Xue Qiangyou used his familiarity with the terrain of the old amusement park to deceive Cui Junjing.At this time, Heidi appeared to fight against Cui Junjing, but she did not expect that Zheng Xiuren was surrounded by the gray team, so she fainted.Xue Qiangyou went outside to steal the car, while Detective Jiang took the opportunity to stay outside to eliminate the hounds.This scene was seen by Xue Qiangyou. When Cui Junjing found out that the hound was killed, she vented all her anger on Zheng Xiuren and took her away.
