521 Mysterious Guardian Of Tanulia

Tiriana, who heard these words weakly, opened her eyes. After Michael demonstrated his skills to Atian and Alred three days ago, he went to one of Michael's restaurant competitors: The Ruby Cuisine. 

Michael poisoned her food with Blood tonic without her knowledge or anyone. Ever since that day, Michael has been controlling the nanites and causing her pain. 

(Chapter 495 mentions Tiriana's arrival at Idrisal)

Tanulia found the Spyders because of Noah. They thought they found all the Spyders in the warship except the one Michael left in Peyton's body.

Michael knew they had found the Spyders and tried to manipulate him by feeding him false information. But Peyton's dedication to catching him really surprised Michael. 

She really went all in, and if it wasn't for the Spyder in her body, Michael would have been in the interrogation room right now instead of in Tiriana's room.
