Houshan is outside the back door of the medical school. Pen % fun % Pavilion www.biquge.info

Walking back from the girls' apartment is a small sports field, next to the sports field is a small garden with pavilions and promenades, next to swings and seesaws and other fitness and entertainment facilities, and then there are several small red brick buildings, hidden in the red, green and green trees, this is the faculty dormitory of the medical school.

Kang Xueru lives alone in a small two-story building because of his high rank, and now this house has been temporarily sealed by the police.

Su San and Yan Ying stood at the door of Kang's house, looking at the back door not far away.

Luo Yin pointed to the back door and said, "It seems that you can enter and exit at will during the day." ”

"Yes, the door won't be locked until after ten o'clock in the evening." Yan Ying pointed to the small red brick building not far away and said, "Oh, there, the largest building is an ordinary staff dormitory, and the old way of guarding the door is here, and I will come to lock the door at ten o'clock every night." ”

Walking to the door, Luo Yin saw a string of iron chains hanging on the iron door, with a big lock hanging on it, he pulled it with his hand, and the iron chain rattled a few times.

"What time did the rain stop on the day Ma Ning died?"

"I remember, it's past eleven o'clock in the evening, right? The woman at the food stall said that Ma Ning had gone to her to eat after the rain had stopped. ”

Su San replied.

"That's not right, lock the door at ten o'clock, how did he get out." Yan Ying pointed to the big lock and said.

"The guy who asked him out might have the key."

Luo Yin thought for a while and continued: "What is the name of the girl you are talking about? Hu Yanping: Right, what is her relationship with the janitor? How likely it is to get the keys. ”

Yan Ying shook her head: "I don't know, in addition to my own classes, I also have to be Mr. Kang's assistant, and I am also in charge of Mr. Kang's laboratory, I am busy hitting the back of my head every day, and I don't have much contact with these students, I recognize their handwriting, because their homework is handed over to me, and I don't know anything else." ”

Luo Yin nodded, his eyebrows twisted into a pimple.

As Su San said, this matter is surrounded by a layer of fog, making it impossible to see everything around them.

The deaths of two people who seem to have nothing to do with each other are connected by Mrs. Kang.

The three of them walked out of the back door, and Su San pointed to the mountain and asked, "If you don't go through the back door, how long will it take to walk around the front?" ”

Yan Ying shook his head and said: "This is impossible, because if you go this way ahead, you have to pass by a big lake, and if you can't get over, you can only go up the mountain through the back door, or call it the back mountain, a complete back mountain." ”

"It seems that someone else has the key to this back door." Su San looked at Luo Yin, who nodded and pointed to the mountain road and said, "Let's go, I saw the records of the scene through the relationship at the police station, there is a cave not far from the place where Ma Ning died, and they also went in to check it and found nothing." ”

The three of them walked up the mountain road, Su San was out of breath when he walked, Luo Yin turned around and stretched out his hand, Su San held his hand, and the two looked at each other and smiled. Yan Ying shouted: "Oh, don't bring this, make me jealous, bully my boyfriend is not here, isn't it?" ”

Su San smiled and stretched out his hand: "Okay, come, hold my hand, I'll pull you." ”

Yan Ying gently slapped her hand down: "I don't hold it, it's so sad for me." ”

Luo Yin saw that Yan Ying's expression was very relaxed, so he asked curiously: "Miss Yan, one of the deceased is your boss and the other is your student, but I don't think you take it seriously at all." ”

"What does Mr. Luo want me to take seriously? Sad? Crying eyes red? ”

Luo Yin coughed dryly, laughed and said nothing.

"Luo Yin, he didn't mean that......"

Su San hurriedly wanted to divert the topic. Yan Ying waved her hand: "I understand what you all mean, Su Su, what do you still say, you are not interesting enough, didn't you suspect me at first?" ”

Su San smiled and looked at Luo Yin, who looked up at the sky, pretending that I couldn't hear anything.

"Mr. Luo, I grew up in the barracks since I was a child, and since I can remember, the most I have seen is a soldier, and then it was the war, and the uncles and big brothers I have been familiar with since I was a child are gone one by one, and finally my father."

Su San held her hand, and Yan Ying continued: "So I have known this truth since I was a child, life and death are helpless things, and then my mother died, it was cancer, our family, our military camp back then, I was the only one left." Over the years, I have been accustomed to seeing life and death, and I don't think these are things that make me sad at all, and then I studied medicine, and I have to face too many life and death illnesses every day, Mr. Luo, do you think I will still be sad for the death of a person who has little to do with me? ”

Luo Yin nodded: "It's me who is too worried, please forgive me." ”

"It's nothing, something like this happened all of a sudden, and I also see that everyone is a murderer." Yan Ying is very reasonable.

The three of them quickly walked to the vicinity of the cave.

Luo Yin pointed to a tall soaphorn tree next to him and said, "I saw the police record, Ma Ning was lying under that tree." ”

Su San and Yan Ying stood under the tree, Yan Ying casually pulled a half-black soap horn, shook it in her hand and said, "How Ma Ning died, I'm afraid only they know." ”

The three of them walked into the cave, which was not big and looked no different.

The three of them walked around the cave wall, and Su San pointed to the vines behind him and said, "The mechanism should be here." He said that he was going to reach out and touch the vine.

Luo Yin shouted: "Slow! ”

But Su San had already stretched out his hand, and suddenly a slender black shadow burst out from the pile of vines, Luo Yin saw that it was too late, and he didn't want to smash the flashlight in his hand, and with a snap, the flashlight and the black shadow fell to the ground together, and it disappeared after a few swishs.

Yan Ying was so frightened that she pulled Su San's hand: "It's a snake, that's a snake!" Susu, are you alright? ”

Su San shook his head: "No, it didn't bite me." ”

Luo Yin picked up the flashlight and picked up the vine with a flashlight: "Do you think Mrs. Kang knows that there are snakes here?" ”

Yan Ying said: "It's hard to say, it's dark and damp here, and it's normal to have snakes, right?" ”

Su San agreed with Yan Ying's statement: "I think Mrs. Kang is in a hurry, it doesn't look like a lie." ”

"A woman's heart is a needle." Luo Yin sighed. ’

Yan Ying snorted and laughed: "There are two undersea needles here, Mr. Luo, be careful to prick you." ”

"I think if we weren't here, he would probably say that there is no more poison than a woman's heart." Su San teased.

Luo Yin shook his head helplessly, these two young ladies are not allowed to share.

Sure enough, there was a stone sticking out behind the vines, Luo Yin reached out and touched the stone, the stone moved, and then clattered, and the stone wall behind it also moved.

Luo Yin hurriedly pulled one in one hand and quickly stepped back.

When the stone wall flashed open, the hole was revealed.

Yan Ying opened her mouth wide in surprise: "My God, there really is a hole in the hole." ”

Luo Yin turned on the flashlight and swept it in, it was dark inside, and he couldn't see anything.
