At this point, Lin Yu knew that he couldn't wait any longer, so he decisively decided to act, as long as he caught this Zhang Youxi, maybe he would be able to find Ling Xiao along the vine, or even leave the fire path for Wan Xiu.

"Okay, then I'll keep staring here!"

Bu Cheng said in a deep voice, "That Xiao Ai said that she would come over in the evening when she left, I think after she comes, Zhang Youxi will be more relaxed, and when the time comes, we will take the opportunity to catch the two of them together!"

"Well, there are many people during the day, and it is most appropriate to do it at night!"

Lin Yu said in a deep voice, in addition to saying that there are many people during the day, there is another meaning, knowing that Zhang Youxi, as the second master of the Zhang family, will definitely have many people secretly help him, it is estimated that this is also one of the reasons why the Military Intelligence Department searched so strictly, but never caught him and Ling Xiao.

Therefore, it is naturally more convenient to act at night.

"By the way, Brother Bu, did you stay there all night?!"

Lin Yu suddenly remembered something, and Chong Bucheng asked in a low voice.

"Well, stay here all night!"

Bu Cheng agreed, "This Xiao Ai is the same as last time, he stayed in it all night and didn't come out!"

Lin Yu raised his eyebrows, a hint of playfulness flashed in his eyes, the lonely man and the widow stayed together all night, anyone could have thought of what would happen, but I didn't expect this Zhang Youxi to have such a special relationship with Xiao Ai.

"When did Zhang Yousi and Sister Xiao Ai say this morning, Zhang Youxi will leave tomorrow? Do you remember the specific time clearly?!"

Lin Yu looked a little cautious and confirmed with Bu Cheng again, for fear that he had heard it wrong.

"I can't remember the specific time, anyway, it was early in the morning, when Zhang Youxi was in the yard when he sent Xiao Ai out!"

Bu Cheng thought about it carefully and said with great certainty.

"When I send her away......"

Lin Yu squinted his eyes and didn't speak again, as if he was thinking about something.

"What's the matter, sir, what's the problem?!"

Bu Cheng on the other end of the phone asked suspiciously.

"Nope!"

Lin Yu shook his head and said, "Brother Bu, you must be tired after keeping watch all night, why don't you go back and rest first! Just let your subordinates go over and watch for you, so you don't have energy at night!"

"No, I'm here to keep an eye on the insurance!"

Bu Cheng said indifferently, "This is nothing to me, I used to have no problem not sleeping for two or three days in a row!"

Lin Yu saw that Bu Cheng was so insistent, so he didn't say anything, there was indeed Bu Cheng watching here, it was safer, anyway, Bu Cheng only needed to hold on until the evening.

After Lin Yu got up, he went directly to find Bairen Tu, at this time, Bairen Tu had just gone to send Yin Er back from school, after listening to Lin Yu's words, he also nodded, and felt that it was most appropriate to act at night, and he and Lin Yu agreed with each other, and he also felt that he could not inform the Military Intelligence Department in advance, in case of leaking the news, I am afraid that it would fall short.

In the evening, after Lin Yu and Bairen Tu followed Yin Er home, Ye Qingmei had just come back not long ago, and was cooking in the kitchen.

After Ye Qingmei's meal was ready, Jiang Yan hadn't come back yet, Lin Yu couldn't help but wonder a little, and said, "Sister Yan, what's the matter, what time is it, and you haven't come back yet?!"

Now that Jiang Yangui is the director of the department, he no longer needs to be on duty, so normally he can get off work every day.

"Have you forgotten? She said the day before yesterday that a seriously ill patient needs to be tested today, and she may not come back until late!"

Ye Qingmei walked out with the food while reminding Lin Yu.

"Ao, yes, Sister Yan said it, look at my memory!"

After Ye Qingmei's reminder, Lin Yu remembered this stubble, and he seemed to have promised to pick up Jiang Yan at night, he hurriedly looked up at the watch on the wall, turned around and asked Ye Qingmei, "Senior sister, what time does Sister Yan get off work?!"

"It seems like it's past ten o'clock, right?!"

Ye Qingmei thought for a while and said, "You can go over and pick her up before half past ten!"

"...... before half past ten"

Lin Yu muttered in a low voice, and then sent a text message to Jiang Yan, saying that if she couldn't pass at half past ten, let her wait for her.

After eating, Lin Yu and Bairen Tu handed Yin Er to Ye Qingmei, and then the two went to Xiao Ai's studio together, and saw that there was a coffee shop diagonally opposite the studio, so they went to the second floor of the coffee shop, drinking coffee while staring at Xiao Ai's studio.

At about half past nine, the lights in Xiao Ai's studio were turned off one after another, and it seemed that the day's work seemed to be over.

Then the employees in the studio walked out one after another, but there was no Xiao Ai.

Until the lights in the entire studio were turned off, everyone was gone, and the door was locked, Xiao Ai was not seen.

Seeing this, Lin Yu suddenly became nervous, squinted his eyes and carefully glanced at the dark studio, thinking that something was wrong, just now I saw a figure in front of the workbench on the second floor that looked like Xiao Ai, why did everyone go away, and I didn't see her come out?!

Just when Lin Yu hesitated whether to go down to check, he suddenly found a tall figure in a windbreaker coming out from the back of the villa, the figure stood up the collar of the windbreaker to block half of his face, looked around very cautiously, and then turned around and walked quickly towards the villa.

"People are coming, Brother Niu, go!"

Lin Yu glanced at the figure and hurriedly got up, although he didn't see the face of the figure, he could conclude that this figure was Sister Xiao Ai, because he could judge the strange feeling on Xiao Ai's body!

Bairen Tu also believed Lin Yu's judgment, didn't ask anything, and hurriedly got up and followed Lin Yu out quickly.

Because he was afraid of being discovered by Xiao Ai, Lin Yu and Bairentu followed them relatively far, but fortunately, Bu Cheng sent Lin Yu the specific location of Zhang Youxi's residence during the day, so Lin Yu was not afraid of losing it.

After Xiao Ai went out from the small door of the villa area, he turned directly into a courtyard area, and at the same time, while walking, he looked back from time to time.

In the end, she turned around and came to a courtyard in the depths of the courtyard area, and did not knock on the door, took out a key from her bag and inserted it directly into the keyhole of the gate, opened the door and flashed in, looked back left and right, and saw that there was no figure on both sides of the empty road, so she breathed a sigh of relief, closed the door directly, and locked it.

At this time, Lin Yu and Bairen Tu poked their heads out from a roof not far away, and witnessed Xiao Ai walking through the courtyard and straight into the hall.

"Sir, this is where Zhang Youxi lives?!"

Bairen Tu asked in a deep voice with an expressionless face, then looked left and right, and wondered, "Why didn't you see Bu Cheng?!"

"Here's it!"

At this time, a low and cold voice came, and at some point, there was suddenly a figure next to them.

"You've grown!"

Bairen Tu glanced at Bu Cheng and said lightly, he didn't expect Bu Cheng to be light, and even he didn't notice it.

"Then you still have to say it!"

Bu Cheng said without modesty.

"Brother Bu, how is it, this Zhang Youxi is still inside, right?!"

Lin Yu hurriedly asked him after seeing Bu Cheng.

"Well, I came out at noon to buy something to eat, and I never came out after I went back!"

Bu Cheng nodded and said with great certainty, because he had been staying here and had not left for almost a moment.

"Is he living here alone?!"

Lin Yu continued to ask.

"Well, it's him!"

Bu Cheng nodded affirmatively.

"Okay, I don't know much about this Sister Xiao Ai's skills, but it shouldn't be too profound, after we rush in for a while, Brother Niu is responsible for restraining this Xiao Ai, and I am responsible for dealing with Zhang Youxi!"

Lin Yu looked at the lights in the courtyard and whispered to Bairen Tu and Bu Cheng.

"What about me, sir?!"

Bu Cheng hurriedly asked, why is this not his business.

"Brother Bu, you are the most important link in this operation, you have to hide on the roof for a while, and after we fight, Zhang Youxi or Xiao Ai will definitely find a way to escape, you are responsible for ambushing them, and strive to take advantage of their unpreparedness and injure them in one fell swoop!"

Lin Yu said in a deep voice, for people like Zhang Youxi, there is no morality at all, as long as he can lose the ability to resist, even if he can sneak attack, it is not impossible.

Bu Cheng didn't object when he heard this, and nodded vigorously.

Seeing that the time was almost up, Lin Yu squinted at the lights in the courtyard and said coldly, "Okay, do it!"
