The next morning, Xu Sa and Su Tong went into the house on time to inspect before Ji Yong went to work.

"Don't mind, do you?" Su Tong pointed to the wardrobe, and Ji Yong nodded gloomily.

After Ji Yong's consent, Su Tong began to rummage through the clothes in the closet one by one. After unpacking the clothes on the hanger, I found a small suitcase and took a secret breath.

Ji Yong's eyes were full of doubts when he looked at this suitcase.

According to Ji Yong's appearance, if the evidence of Li Aiyin's cheating was put out in front of him, he would probably go crazy.

Wearing the gloves of evidence collection, carefully unzipping the suitcase, is a makeup case, and a few erotic underwear.

Su Tong took out the makeup box, and after opening it, there were all kinds of cosmetics and perfume jewelry. Push open the first floor, and a key comes into view.

"Mr. Ji, this?" Xu Sa asked without changing his face.

"I don't know when there's a box here." Ji Yong turned his head away, covering his face with his hands, as if he couldn't face the situation in front of him.

After putting the key in the physical evidence bag, Su Tong looked at Xu Sa and nodded, indicating that he was enough.

"Then, Mr. Ji, if you have anything else to add, feel free to contact me." Xu Sa wrote down the phone number of the police station and handed it to Ji Yong.

After this toss, Ji Yong didn't have the heart to go to work at all, and after sending Su Tong and Xu Sa out, he closed the door.

"You say, what kind of key is this? Li Aiyin actually hid it so deeply. Su Tong looked at the key over and over again, the key was very brand new, with only a few scratches, indicating that the degree of use was not high.

"I don't think it's useful to take this key back for testing. I should have tried it at her house with this key just now. Xu Sa wiped a handful of fine sweat from his forehead.

"You underestimate women too much." Su Tong adjusted his breathing and glared at Xu Sa. "Since she was able to leave the key at home, it proves that she is sure that Ji Yong can't find a lock that can be opened with this key."

Xu Sa said that he didn't care about Su Tong's glare. He doesn't need to understand other women, it's enough for him to understand Su Tong, well, that's it.

"I just took a closer look, and the wardrobe is full of some home clothes, and I don't seem to see the dresses that Li Aiyin wore before." Su Tong grabbed the handrail of the stairs with difficulty, and stopped to rest while he was talking.

Since Su Tong's elevator was in distress, the elevator is unusable no matter what. Xu Sa has received strict military training, climbing the stairs is difficult for him, Su Tong is miserable, although she has received regular military training, but she pays more attention to her own profession, and does not pay special attention to physical training on weekdays, the most important thing is that after yesterday's elevator shock, not only her ears have not recovered, but even her knees and ligaments have not recovered well.

After climbing six floors, Su Tong leaned next to the handrail, "You...... You go first, and I'll be there. Seeing Xu Sa waiting for her condescendingly, she was also a little embarrassed.

"Eh......"

Xu Sa said for no reason, and pulled Su Tong's hand that was still fanning, "Forgot last night's text message, didn't you!" Xu Sa turned around and said viciously.

Su Tong stuck out his tongue, and the warmth from his wrist was the same as the touch he felt before he passed out last night. With Xu Sa's hand, Su Tong finally reached the twentieth floor before his calf cramped.

"Whew-"

Xu Sa let go of Su Tong's hand, hesitantly looked left and right, and after confirming that there was no abnormality, he waved his hand to signal Su Tong to approach Li Desheng's unit.

Su Tong also nodded vigilantly and slowly approached. After Xu Sa confirmed that the danger had been investigated, the two of them breathed a sigh of relief.

"How?" Xu Sa saw that Su Tong was standing at the door and didn't make the next move, so he asked suspiciously.

Su Tong made a bitter face, and his fingers neatly cut open the stainless steel panel above the doorknob. "It's a fingerprint lock."

Xu Sa quickly pondered in his heart, "Do you want to call back to find technical support?" ”

Su Tong hesitated for a moment and asked hesitantly, "The problem can be solved, but you can't say it." ”

Xu Sa raised her eyebrows in surprise, does she have a way to open the fingerprint lock?

Su Tong took out two No. 5 batteries from his bag, took out one, groped under the handle, and after finding the position, he put the positive direction of the battery against the protruding nut.

Push the panel open, press the asterisk button, and slam the doorknob down.

"Smack-" The door opened.

Xu Sa's eyes were not good. "When did you get this skill?" Su Tong did not respond to this question.

She wouldn't tell Xu Sa that she used to use this fingerprint lock at home, and occasionally the panel of fingerprint recognition was short-circuited, and the maintenance staff of the door lock company taught her this method of opening the door. It's also great to let him take a good look at her.

"Now notify the people of the second team to collect evidence, this door lock is scrapped, and there are fingerprints on the identification panel carefully."

"How do you know it's scrapped?" Xu Sa carefully moved the small stool in the entrance hall to the door and held the stainless steel door.

"Opening the door with this method is to open the forced unlocking set inside the electronic lock at one time, and it can only be used once." Su Tong walked in and observed the room of the famous big owner of the community.

The area of the unit is very large, and it should be that Li Desheng bought two connected units, and what he saw was a spotless living room, followed by the master bedroom next to the back of the living room, and Xu Sa followed behind to open the doors one by one.

Su Tong came to the outside of the guest room, and when he wanted to open it, he found that the door was locked.

"Why is the guest room locked?" Xu Sa tried to press the doorknob as well, but it really couldn't be opened.

How can the owner's own bedroom be locked without locking, and the guest room is locked?

"Generally, the key to the door lock will be inserted on the new house soon after the renovation is completed, but now the door of the whole house is only locked in this room." Su Tong touched his chin with one hand, wondering if there was something important in this?

Xu Sa walked to the bathroom opposite, pulled out the key inserted on it, and looked around again.

"Look, doesn't this key sound familiar?" Xu Sa handed the key to Su Tong's eyes.

After Su Tong took it, "It's very ordinary." ”

Xu Sa shook his head, "Don't you think it's very similar to the key we just got?" Xu Sa's words were like a sharp knife cutting an impenetrable balloon, and suddenly all kinds of strange phenomena began to become smooth.

"No," Su Tong tugged at the corners of his mouth, "I don't dare to write like this in TV series......"

A maiden woman cheated on her neighbor in the same building...... It's right under my nose......

Xu Sa didn't talk nonsense, took out the key directly from the evidence bag, and inserted the key into the lock cleanly.

"Reality is often much heavier than the taste of TV dramas."

As soon as Xu Sa's voice fell, "Bang-" The key turned, and the door opened.
