The Untouchable Ex Wife by Mizuki Sei

Chapter 1790
"Of course!" Justin raised his chin proudly. "Nobody can beat me in that, not even you, Phoenix. Isn't that right?" "Yes, that's true." Renee nodded, giving him a thumbs up. She was being humble because Justin was more skilled than her in that area, and the one time Justin beat Renee to become champion of the Global Hacker Competition, he had done it by defeating her at cracking IPs.
"Why are you asking?" Justin's eyes brightened, and he asked Renee excitedly, "Are you planning to compete with me at the Global Hacker Competition this year? If Haze and Phoenix, the perfect couple of the hacker world, made a comeback this year, there'll be an uproar!" Justin rubbed his hands together eagerly. When Phoenix retreated from the hacker competition, Haze followed suit, and even left the hacker world. Their story became a legend in their circle, and everyone had heard about it even if they had never met them. If Renee wanted to return to the circle again, Justin would immediately follow suit.
"I'm not interested in competing against you but... I need your help," Renee said calmly.
"My help?" Justin frowned in disappointment. "Is that the only thing you want?" "Yeah." Renee nodded.
"What do you need my help with then?" Justin asked curiously. "Is it related to private IPs?" "You're so smart!" Renee praised Justin like he was a child. "You're my soulmate-you know what I want to say before I can even say it. I love spending time with smart people like you." "Ugh, stop it." Justin knew something was up, and he narrowed his eyes at her suspiciously. "What do you need my help with? spit it out." "Well, I'm not sure if you can do it, but..." After a brief pause, Renee said, "If someone texts you but immediately deletes the message, can you still find that person's address from the deleted message?" "Isn't that simple? He has to log in to text you, and as long as he logs in, there'll be a record of his IP address. It'll be a piece of cake to figure out!" Justin scoffed, looking smug.
"You're right, why didn't I think of that?" Renee nodded, smiling at him sweetly. "You're so smart. No wonder you could defeat me back then, you really deserve to be the champion." "Our skills are pretty much at the same level. At most, I'm only a little better than you." "No, I'm sure you're much better than me..." Renee pressed, then quickly asked, "So, can a capable person like you help me crack this account and find his IP address?" "No problem." Justin snapped his fingers. "Give me the account. Who do you want me to find?"
