Although it was the first time to enter No. 89 Hospital, after listening to the introduction of Ma Wu and the police officers, I was still very kind to this small courtyard. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoThis yard is supposed to be divided into a large courtyard, which is smaller than my yard. It is estimated that the big locust tree in the northwest corner of the yard was planted when the yard was repaired, and after the yard was separated, its position was very awkward. In addition, the yard is smaller, and the trees are growing day by day, and now the shade of the trees covers almost half of the yard, which seems a little incongruous.

Grandma Cai was sitting in the courtyard with Mr. Cai basking in the sun, the courtyard door was not closed, we entered the yard, Grandma Cai quickly got up, and greeted him with a puzzled expression. Xiao Lei took out his police officer card and handed it over, while Team Cao put a box of Daoxiang Village dim sum that he had just bought from Ma Wu's store on the small stone table in the courtyard.

Xiao Lei introduced Team Cao and me to Grandma Cai, and it is estimated that the old couple had never been such a high-level leader in their family, but they were a little at a loss and were busy pouring tea for us. Taking advantage of Grandma Cai's efforts to pour tea, Team Cao briefly said our intention. mentioned Lao Zhang, and Grandma Cai's eyes turned red all of a sudden.

She sat us down in the courtyard and began to ramble on and on. Grandma Cai's speech is completely illogical, she can talk about it wherever she thinks, although the legs and feet of the old man Cai next to her are not very convenient, but his brain is still clear, and he often interjects a few sentences to bring Grandma Cai back to the topic.

I already know most of what Grandma Cai said, but there are two points that caught my attention. One is that when Lao Zhang first moved in, that Zhao Shaocheng came to the courtyard to see him a few times, but judging from Grandma Cai's description of Zhao Shaocheng, it should not be Wu San, but the person Lao Zhang met in Wu San Casino. Another point is that about half a year ago, the tenant of the West Wing checked out and left, and Zhao Shaocheng came to rent the house that afternoon, and gave a year's rent at one time. Grandma Cai already trusted Lao Zhang very much at that time, and knew that she was Lao Zhang's friend, so she rented it to him without thinking about it.

But the strange thing is that Zhao Shaocheng rarely lives here, and he stays for no more than 10 days in half a year, which makes Grandma Cai a little confused, and he spends all this money to rent a house and does not live there, what is his purpose? Lao Zhang told her that Zhao Shaocheng has a big business in Hebei and is very busy, and he also works for him, and he only lives in the courtyard for two days when he came to Beijing to contact business. Although Grandma Cai didn't ask much at the time, since Zhao Shaocheng moved in, the accidents and strange things in the yard began. Moreover, before Lao Zhang's car accident, more than a week to now, Zhao Shaocheng has never been here again.

Lao Zhang's story, Cao Team and Xiao Lei listened to it with relish, and interjected two sentences from time to time, and Grandma Cai was not annoyed, and patiently told them while reminiscing. I stood up and walked under the big locust tree, and looked closely at the mottled shadows.

In addition to the size and thickness of this big locust tree, there is another obvious difference between this big locust tree and the common locust tree, that is, its trunk is very straight, almost four or five meters high, and the trunk begins to stick outward.

If you climb directly from under the tree, it is estimated that it will be very difficult for ordinary people, no wonder Xiao Liuzi had to get a ladder to climb up that time. Half a meter next to the big tree is the courtyard wall on the west side, about two meters high, climb the wall, and it is still possible for people with good skills to climb the tree again. But no matter what, if you can climb a tree to hang a cat, and you can not alarm the nervous breakdown of Old Man Cai, you will definitely not be able to do it without some ability.

I walked around the yard and returned to Grandma Cai, who was already in deep love, wiping her tears as she spoke. "Officer Cao, this kid of Jin Guo, although he has not been in contact with him for a long time, he is a good person, motivated, and responsible, although he took a crooked path when he was young and became addicted to gambling, he did not touch it at all after he arrived in Beijing, and he devoted himself to scientific research. Hey, good people don't have good rewards, when he encountered a lightning strike, I persuaded him to go to the temple to burn incense, worship the Buddha, and resolve bad luck, but Xiao Zhang didn't believe in this, and he didn't go, but it's a pity. ”

"Grandma Cai, is there anything special about Lao Zhang's usual living habits?" Xiao Lei asked on the side.

"It's nothing special, it's just that life is irregular, they sleep late at night, they often get up late during the day, they do scientific research, they like to be quiet, this is also normal, isn't it?"

"The other thing is that he is full of inventions and doesn't like to deal with people. I've lived here for more than a year, and most of my neighbors don't know me. There are no friends around, except for that Zhao Shaocheng, it seems that no one has ever looked for him. ”

"Oh, and he's not in good health, he's always staying up late, he's had so many things, he's sick all day long. Before he had a car accident, he coughed for a month, and it got worse and worse, and I asked him to go to the hospital to see if he was still alive or dead, so he bought some medicine to deal with it. "When Grandma Cai mentions Lao Zhang, she talks a lot, but in the fragmented description, she really can't see any ulterior secrets on Lao Zhang.

"Grandma Cai, we want to go into Lao Zhang's room to see, although the accident traffic police corps has determined the nature, we still have to investigate clearly, that is, to give Lao Zhang's family an explanation, but also to be responsible for Lao Zhang's unfinished career, do you say this is the reason?" Cao team wasted no time in interjecting.

Grandma Cai hesitated for a moment, patted her thigh and said, "Officer Cao, you are right, although Xiao Zhang is no longer there, his research results must be passed on, and he can't just be scrapped." Wait for me and get you the key. ”

The east wing of Lao Zhang's house is close to the courtyard next door, there are no windows on the east side, and the two small windows on the west side are blocked by the big locust tree opposite, and the house looks very dim. Although no one came in for a few days, there was still a musty smell, and the soil was very thick, and when the door was opened, there was a small wind, and the dust flew gently, and the light was bright and dark, as if in an ancient catacomb.

Xiao Lei turned on the light switch, and as Grandma Cai said, we clearly heard the sound of "popping", and the light flashed a few times with the sound before returning to normal. On the opposite side of the door, on a long writing desk, six or seven radios of all kinds were stacked high and low, and various display lights were staggered and lit up at the same time, as if it was the central console of the rocket launch site, but it made people have an inexplicable sense of sadness in the end times.

Team Cao stepped forward and was about to fiddle with the radios, when Xiao Lei grabbed him.

"Team Cao, I still know a little bit about radio, don't touch it yet, let me take a look first, I think the important thing may be the band frequency law that I used before. As he spoke, he sat down at his desk and looked at each radio one by one.

Team Cao spread his hands to me, smiled bitterly, and pointed to the top of his head, I followed his finger to look up, the ceiling above my head, densely lined with a lot of bare copper wires, around the electric lamp above a flat black box, circle by circle outward, at first glance I thought it was a huge spider web. A basket of two wires from the black box ran down the wall and connected to the radios.

"Lao Chang, what do you say this thing is? Didn't Lao Zhang teach mathematics? Why did he still make these new things?" Team Cao moved a chair and sat down, looking around curiously as he spoke. Without waiting for me to answer, Xiao Lei, who was sitting in front of the desk, didn't leave the radios, but replied, "That black box should be a signal amplifier, and the copper coil outside is a simple receiver, this thing made by Lao Zhang is very strange, and I haven't figured out what it's used for." After saying that, Xiao Lei stopped paying attention to the two of us, put on the headphones on the table, and began to listen with a frown.

The east house that Lao Zhang rented was not big, only more than 20 square meters. The furnishings in the room were unusually simple, except for the desk and radio, there was only a single wire bed and a simple wardrobe. There was also an old-fashioned suitcase covered in cloth in the corner of the house, and there was nothing else superfluous.

I saw a bedside table at the head of the bed, and some books were piled up on it, so I went over and picked it up and looked through it. The top two books are professional books on radio technology, which I don't understand very well, but Lao Zhang made a lot of notes and drew some sketches on the blank pages, which seem to be the drawings of the radio series on the desk. I put these two books aside, the next one is "Zhou Yi Shen Tong Deed", a thread-bound version of "Zhou Yi", and a copy of Shao Yong Shao Kangjie's "Plum Blossom Easy Count".

Judging from the degree of damage to the book and the notes made by Lao Zhang in the book, Lao Zhang's attention to these books is far more than the two radio professional books, but I am very puzzled in my heart, this Lao Zhang is becoming more and more incomprehensible to me, why do you still study Zhou Yi gossip?

"Zhou Yi" itself is one of the four books and five classics, should be the most widely circulated and authoritative canon about the Book of Changes, "Zhou Yi Shen Tong Qi" is a classic work of Taoism, but more about numerology and the study of the cultivation of Neidan. The book "Plum Blossom Easy Counting" is a unique deduction method of the Book of Changes, which seems to be easy to understand on the surface, but in fact, the deeper you go, the more mysterious you feel. However, the biggest role of plum blossom is the prediction of some emergencies. Judging from the reading choices of these books, Lao Zhang must also have studied from shallow to deep, from broad to specialized.

But what I never understand is, what does Zhou Yi have to do with radio? Listening to the descriptions of Ma Wu and Grandma Cai, I think Lao Zhang is a very organized and targeted person, and he must have studied these two completely unrelated things together for some important reason, but what is this for?

(The teachings of Confucianism teach people to obey their lives in order to return to creation, and their Taoism is just.) The teachings of Zen Buddhism teach people to live illusory lives with super-great enlightenment, and its righteousness is high. The old religion teaches people to cultivate their lives and achieve immortality, and its purpose is keen. Although there are three teachings, there is one way. --"The Purpose of Life")
