Long Xi said: "I have seen those in the living room, and there are several reasoning books that are the works of Mr. OU in the past few years, which are indeed very exciting, very creative, with exquisite layout, unique techniques, and unexpected endings." However, Mr. OU did not write it in the past few years. I found in the utility room an old book that he published seven years ago, and it was poorly written, patchworked, and nothing new.

MK said, "Not really, I don't like it. Based on your analysis, do you suspect that he has a 'gunman'?"

Long Xi said: "Yes. I suspect that the 'gunman' was a brilliant photographer for SI, but for some reason he was forced to be imprisoned in a basement here, forced to write for Mr. OU, and may have suffered some betrayal and abuse! Because I have observed the fingers of the headless male corpse, and the skin tone is very even. If it was Mr. OU, then he wore a wedding ring all year round, often went out to fish, often enjoyed the sun by the beach, and his finger should have traces of a ring, and there should be a circle of traces of light skin tone, right?"

MK thought for a moment and said, "Makes sense. ”

Long Xi said: "If that's the case, then the murderer is likely to be Mr. OU." But I don't think it's going to be that simple. If Mr. OU killed his 'gunman' in order to kill people. So, why did he kill the others? Could it be because they were insiders? No, right? I don't think those people had known for a day or two, so why did he do it now? Also, SU once said that he was back! He came back to take revenge! Could it be that the 'he' in her mouth was LU? Could it be that LU escaped and is now back for revenge?"

MK stopped doing push-ups, wiped the sweat from his forehead with a towel, and said, "Why don't we go ask the BA master......!" Hmph, he dared to do such a thing to his wife, and I would not let him go! Madame treated me very well, just like her own brother!"

Long Xi looked at him curiously and asked, "Do you really have the seven emotions and six desires of human beings?"

MK smiled and asked, "Can't you? I tell you, it won't be long before those AI robots will have human feelings, believe it or not?"

Long Xi shrugged noncommittally and walked to the kitchen with MK.

The kitchen door is open!

MK rushes into the kitchen and sees that it's empty!

"No way! I'm tied it so tightly and tied a few dead knots, there's no way he'll run away!" MK said.

Long Xi said, "What about Mrs. LI? She won't be in danger, right?"

MK rushed up to the second floor with a bloodless face and kicked open the door to Mrs. LI's bedroom.

There was an exclamation from Mrs. LI inside, and it turned out that she was changing her clothes!

MK said "I'm sorry" in embarrassment and quickly slipped back to the first floor, his face flushed.

Long Xi comforted him and said, "It's okay! Now the only people alive are you, me, Mrs. LI, and JU." Among the missing are QI and BA. The murderer may be Mr. OU, and the BA boss and LU may also be the murderer! But this is all my speculation, and no substantial evidence has been found. ”

MK said, "I want to go out and find a BA master, but I'm not very worried about you. ”

Long Xi said: "I think we should go to the old housekeeper's room to have a look." Maybe the basement is under the old butler's room, and the BA master is hiding in the basement. ”

MK said, "Okay, I'll go with you." ”

The two went to the old housekeeper and his wife's room, searched for a long time, and finally found a suspicious box embedded in the wall behind the wardrobe.

"This box...... Could it be the mechanism for the entrance?" MK said.

Long Xi lightly touched the box, and a glowing square appeared on the surface of the box, and the square was divided into ninety-nine and eighty-one square squares by horizontal and vertical lines, nine of which were blank, and the other squares had the number of BT planet.

The BA master has words in his mouth, as if he is calculating something.

Longxi forehead. Oh my God, this is a box similar to the safe where the gun is hidden in the BA family, and there is a complicated nine-square grid calculation problem on it!

Long Xi took a pen and paper and quickly calculated.

The setting of the combination lock of this box is also as perverted as the box in charge of BA, and it is automatically locked if it does not get the correct answer within half a minute.

Well, Long Xi has to admit: her mental arithmetic ability is not as strong as that of the BA master!

"What are you looking for?" Mrs. LI's voice suddenly came softly, startling Long Xi, who was engrossed in the puzzle of the box, and MK, who was focused on watching Long Xi solve the problem.

MK looked back and smiled, "We want to know if there's a basement or a secret passage or something." ”

Mrs. LI pinched her forehead, and there was a hint of sadness in her tone: "Didn't I tell you? No, I drew the design drawings of this place by hand, don't I know that I graduated from architecture!"

Long Xi asked: "Then were you there during the construction?"

Mrs. LI said firmly: "Yes, my husband and I take turns supervising the work, and it is impossible for those workers to do anything." ”

Long Xi said: "Mrs. LI, don't go to the beach these days. Because the next line of the nursery rhyme is 'The big fish devours the most miserable'!"

Mrs. LI said gently, "Of course I won't go now. Alright, I've made breakfast, let's go eat, don't waste time here. ”

As she walked, she suddenly seemed to remember something, stopped, patted her head and said, "Actually, besides the sea, there is another place where there are big fish!"

"Where?" asked Long Xi.

"It's the storeroom!" said Mrs. LI.

MK asked, "You mean the big shark in the freezer?"

Mrs. LI nodded.

MK said, "I put the headless man's corpse, AN's, and the old butler's corpse in the freezer. Let's take a look at it together, and by the way, put the bodies of SI and SU over there, otherwise they will all rot and stink. Oh, what about JU? Is he sober? I need a helper! You can't do this kind of rough work, can you?"

Mrs. LI said, "I went to see JU just now, and he seems to be greatly stimulated or delirious!"

Long Xi said: "I want to bring JU with me, it's too dangerous to leave him alone in the villa! Perhaps, he also has some clues on him that we haven't noticed before." A person doesn't go crazy for no reason!"

MK said, "Yes, you go and get him to the door." He was tied to a chair with a rope by me, and he couldn't hurt anyone. Tie him a little tighter and bring him down. I went to wrap the bodies of SI and SU in something and carried them off. ”

Long Xi agreed, walked to JU's room with Mrs. LI, and opened the door.

JU was strapped to a chair by MK, his eyes bloodshot and his expression was very irritable, like a beast in human skin.

Mrs. LI walked to the cabinet to find a rope, and Long Xi walked to JU's side.

What she didn't expect was that JU suddenly broke free of the rope and pounced on Long Xi, who was startled and hurriedly dodged, suddenly lost his balance and fell to the ground.

Perhaps it was the sudden "visitor" that stimulated JU again, and he had the irritable reaction when he found SI's corpse again, holding Long Xi down, and waving his fist at Long Xi's face.

Long Xi didn't understand why the rope was loose, and he didn't have time to think about it, so he kicked JU hard, and pushed him off his body with his hands and feet.

Mrs. LI stood aside, as if at a loss.

While Long Xi and JU were entangled, MK ran back from the door in time, grabbed JU's collar, punched him in the cheek, and dragged him away.

Long Xi was able to get out, and hurriedly dragged Mrs. LI out, while turning back and calling MK: "Quickly tie him back on, it seems that someone gave him a rope!"

MK agreed, suppressed JU, and tied JU like a rice dumpling with three or two strokes.

JU's mouth let out a wolf-like howl, which sounded extremely terrible!

MK grabbed a pair of men's underwear from the closet and shoved it into JU's mouth, JU's howl suddenly turned into a low whimper.

Long Xi said: "MK, please look for him and see if his cigarette case is still there?"

MK felt in JU's trouser pocket, found a cigarette case left over from JU's smoking last night, and handed it to Long Xi!

Long Xi opened the cigarette case and saw that there was only one cigarette left in it, and said, "I suspect that someone has done something to JU's cigarette, causing him to go crazy!"

MK thought for a moment and said, "It's possible, too." After all, I have asthma and never smoke, and no one else smokes except BA and the old housekeeper!

Long Xi said: "But his cigarette case is carried with him, and it is difficult for others to do it." Unless it's while he's bathing or sleeping. Mrs. LI, there is no one here except you and JU, there is no one else here to have a bedroom key, right?"

Mrs. LI said calmly: "Actually, there is a spare set of keys at the old housekeeper's! But after the old housekeeper's accident, I checked it, and the keys were gone with QI! I suspect that QI took it!"

Long Xi seemed to be smiling, not angry and arrogant, his eyes looked directly at Mrs. LI, and said lightly: "Why have I never heard you mention it before, there is such a bunch of spare keys!"

Mrs. LI avoided her gaze.
