ng and worried that there was another reason behind it.Especially, she didn't know when he left. Even if he acted at noon, until now, it had already been almost seven hours…But he was like he had disa...Since Lu Yin promised that if Xiao An Nian could open his computer, he could use it freely... 。

In just two days, Xiaonian took advantage of Lu Yin having an important appointment to call him and said he wanted to use his computer to play games

Lu Yin still said the same thing, if he could get it running, just use it. At the end, he jokingly asked Xiao Annian, whether he wanted him to rush home and get it running for him. 。Xiao An's answer, of course, was a refusal. 。When Lu Yin returned home in the evening, Xiao Annian was already asleep. 。He opened his email on his phone, wanting to see what Xiao Annian had done on his computer today. 。Xiaoyan actually found the very hidden cloud backup software he had written himself and logged in. 。He finally opened a file containing sketches of his past designs, and each design was labeled with the time and the two letters 'SX' at the bottom right. 。After using the computer, the little boy cleared his browsing history and played a few games before turning it off. 。That undercover agent is doing a pretty good job. 。Lu Yin pulled the corner of his lips into a smile, neither pleased nor displeased. 。To find out about his background, the man unexpectedly sent a harmless young boy to infiltrate and get close to him. 。However... He didn't intend to directly confront the Tang family anyway. Since Tang Yucheng had already suspected his identity, he might as well take this opportunity while he was in Beis City to tease them a bit. 。Friday 。Lu Yin received a phone call from Tang Moqing at night, saying he wanted to invite him for a meal to thank him for taking care of Xiao Nuannuan and Xiao Anyue this week. 。If there is anything you need help with, feel free to let Luyin know, and if he can help, just let him know. 。As for what came next, Lu Yin didn't respond. He did, however, agree to Tang Mo's invitation for dinner that night. 。After dinner, Xia An returned to the Tang family and took his father into the study. 。"What did you find" Tang Yucheng asked 。The son called himself into the study, surely he had discovered something at Lu Yin's place. 。"These are some old design drawings from my brother, I found them on his computer. There are two letters on them, but I can't figure out what they mean." 。Little An opened his phone album and showed his dad the photos of his designs he had taken. 。Lu Yin had also told him before that drawing design drawings was a hobby, and it wasn't strange that he would put the design drawings on cloud backups. What was strange was the 'SX' two letters behind each design drawing 。Xiaonian couldn't guess the meaning of the English letters, so he secretly took a picture of the design drawing. 。When Tang Yucheng saw the design drawings for the first time, he felt a sense of familiarity. It wasn't until he saw the 'SX' letters in the bottom right corner that his pupils constricted, his breath became erratic, and his heart raced. 。He quickly browsed through a dozen or so design photos, and each one gave him an incredibly familiar feeling. The most important thing was the two English letters 。He has always had a good memory. After closing his eyes and recalling for a while, some memories of the past clearly emerged in his mind. 。Finally, he knows why these design drawings gave him such an uncanny feeling. 。Because he had seen it in Xiu's studio before, but now seeing the design drawings, they were modified, and now they only resembled the original by six or seven points. 。If one design image could be said to be a coincidence, but if every design image has seven or eight points of resemblance, then it becomes somewhat eerie. 。And also on the current design drawing, the 'SX' letters, their initials are the same as those of Si Xiu. 。All kinds of signs indicate that Lu Yin and Su Xiu have a great deal to do with each other. 。And... And...Sirius might still be alive. 。Upon contemplating this guess, which was highly probable to be true, Tang Yucheng's eyes flickered with excited tears. For a moment, he didn't know what to say. 。After calming his excited heart, he said to his son, "Annie, Dad is going out for a while. " 。"Daddy is going to Big Brother's place" Little An guessed. 。He thought that if his father saw these design drawings, he would be so excited that he would definitely go to Lu Yin for a confrontation, or ask him questions. 。 "It's not >>> 。"Tang Yu Cheng didn't explain too much, "Your phone, Daddy took it first. I'll give it back to you when we get back, and go to sleep early." 。"After he finished speaking, he scooped up Xiao Annian in his arms and turned to leave the study. 。"Daddy, I'm big now. I can walk by myself. I don't need to be held anymore." 。"Xiao An felt a little embarrassed, but he didn't struggle to get himself let down." 。Tang Yucheng looked at his son's hypocritical and proud appearance, and he couldn't help but smile. 。And then he sent Xiao An back to his room, reminding him, "Don't tell Mommy about this, okay""Okay, it's our little secret," 。Xiao An nodded, a smile on his face as he agreed. 。Yes, the secret between my father and me. 。"The man repeated his son's words and lovingly rubbed the little boy's hair, "Go take a bath and go to sleep. Or would you like Daddy to help you wash..." 。" No need, Daddy, you should go busy with your work. Go early and come back early. " 。Little An felt that he was already over five years old and couldn't let his father bathe him anymore, except when he was asleep. 。Tang Yucheng left his son's room and told An Xiaotu that he was going out to do something. 。 An Xiaotu asked what was going on, but seeing that he didn't intend to tell her, she didn't pry further. In the end, she just asked if he would be back in the evening. 。Tang Yucheng gave her an affirmative answer and then left the Tang family. 。Tang Yucheng's late-night visit surprised Zhong the Butler. 。"Second Master, it's so late. Is there something the matter" Zhong Butler respectfully inquired. 。Tang Yucheng did not answer Zhong Guanjia's question, only commanding, "Bring me all the keys to the villa, including those to the rooms and drawers." 。"Okay, Second Master, please wait a moment." 。"Master Zhong bowed slightly and quickly retreated." 。In less than three minutes, the butler came back carrying several bunches of keys. 。"Second Master, each key chain is marked with which room it belongs to, and some drawer keys are also on top 。 。"I understand, you go back to rest." 。Tang Yucheng took the phone and went upstairs. 。Meanwhile, Butler Zhong didn't follow. Although Tang Yucheng said he could go back to rest, Butler Zhong didn't really return to his room to continue resting. He straightened his back and sat upright on the sofa. 。The first place Tang Yucheng went was Tang Si Xiu's painting studio. Inside, there were many easels, but the paintings on them had long been taken down by their owner, leaving only empty easels and two or three unfinished half-finished works. 。Every corner of the villa is tidied regularly; therefore, even after several years, the studio remains spotless. 。Tang Yu Cheng opened his phone album, comparing the design drawings Xiao An had secretly taken with the two or three unfinished paintings...o." Tang Yucheng didn't go to his study to work overtime tonight. After taking a shower, he went to bed early with An Xiaotu in his arms.Because he had been busy with the major drug lord case they had...
