Chapter 19 Key Point

Not wanting to create too much turmoil in the court, the key lies in whether enough evidence can be collected to force the other side to retreat. According to Tan Xiaopei, the best strategy would naturally be to present enough evidence and confront the Wang family, as well as those inside and outside the court associated with them, leaving them with no way to argue, calmly withdrawing from all their conspiracies, and allowing the matter to be resolved silently. This way, everyone's face would be saved, and at least on the surface, Dongping would maintain its tradition of no party strife or succession disputes. At the very least, it would prevent Tan Weiming's family from suffering too much of an impact. But if that didn't work, Tan Xiaopei and Nie Rui also had a backup plan. They were prepared to use a series of measures to lure and guide the other side into taking some radical actions. And as long as such actions took shape, with the current preparation of the Intelligence Bureau, the Imperial Guards, and the Tan Weiming and Tan Weiran brothers, they could naturally control the situation in a short period of time, and also collect enough evidence for further action. However, in that case, the court would be more greatly impacted.

Collecting evidence was not really the Intelligence Bureau's forte. This Intelligence Bureau of Nie Rui's, thanks to the suggestions of Tan Weixin and Ye Tao, did indeed have a technical section. Over the years, this technical section had provided intelligence personnel working on the front lines with all kinds of very convenient tools, packaging many useful weapons, tools, medicines, poisons, and other things, allowing intelligence personnel to bring what they wanted to carry into any place to carry out various tasks. The people in the Intelligence Bureau's technical section were most specialized in poisons and tools for assassination, while in terms of field equipment, scout equipment, and observation equipment, the technical section had always relied on Ye's Workshop. Because Ye's Workshop had been researching various scout equipment, slight improvements could be made to equip intelligence personnel. In terms of forensic science, the technical section was very weak. If there was anything relatively decent, it was the technical section's research on handwriting, paper, and ink. The technical section's material room collected almost all kinds of paper and inkstones from all over the world, and there were many experienced masters who were studying the various characteristics of paper and ink, while in terms of handwriting comparison, the technical section relied on its strong network of contacts, and many Dongping calligraphers were willing to cooperate with them, and were often secretly invited to a certain room in the Intelligence Bureau to assist in comparisons. And under the influence of these calligraphy masters, and with more professional training in the Intelligence Bureau, the Intelligence Bureau's own writing experts were about to take shape. These people were even more terrifying than those calligraphy masters. Calligraphy masters could only infer whether or not it was the same person writing from the characteristics of the handwriting, but these Intelligence Bureau writing experts could simulate the handwriting of almost anyone. In order to test the abilities of these special talents, Tan Xiaopei even had a writing expert impersonate his own handwriting to write imperial decrees and some other things, and send them to close ministers... As a result, out of a total of fourteen documents over three days, only Huang Xuping recognized the impersonated handwriting. But Huang Xuping himself was a master of calligraphy and painting, and had a certain understanding of this kind of subtle thing. No one else recognized that it was written by someone else.

However, the Intelligence Bureau's research in other forensic sciences was lackluster. The invention and development of photography had given the Intelligence Bureau a powerful tool in many businesses, but at best, it was just cooperating with sketching and other drawing techniques to train some portrait artists and establish a preliminary detection and comparison system for intelligence agents from various countries. In other aspects, it was a blank slate. In Ye Tao's mind, the most magical thing in forensic science was not these things. Whether it was handwriting or face, they were just the basics among the basics, and could only understand whether it was this person, and who this person was, but could not understand what this person did. The magical trace technology could do this, and could provide intelligence personnel and criminal investigation personnel with more thinking and reasoning basis. The identification and comparison of fibers, hairs, particles, etc. were all components of this mysterious trace science, and these all required a huge database accumulation, a long period of data collection, and professional personnel with solid professional foundations who had undergone long-term professional training, as well as sharp minds. Ye Tao and Tan Weixin spent a full three days, separately dictating and summarizing a content of fifteen thousand words, describing forensic science including trace evidence, and even including fingerprint comparison and other content. Ye Tao even easily created a set of tools for collecting fingerprints. This thing reached Nie Rui's hands, and made Nie Rui and the people around him almost forget the most important thing in their hands in a short period of time. There was no shortage of good criminal investigators transferred from local government offices in the Intelligence Bureau, who could piece together the case and find the real murderer through those details, but no one had ever been able to classify and summarize such a complex system to such a precise level. And fingerprint comparison was even more content that everyone had never thought of. Some of Nie Rui's staff insisted that just fingerprinting alone, if it could be put into practical use, could increase the detection rate of ordinary criminal cases by at least 30%. You must know that the set of tools that Ye Tao gave could not only extract fingerprints from smooth surfaces, but even included some tools for extracting fingerprints from complex surfaces. Ye Tao and Tan Weixin had realized all the knowledge they learned from watching the series of American dramas "Crime Scene Investigation" back then. He was powerless to do computer comparison and other things, but the evaporation and adsorption of glue particles to present fingerprints on complex surfaces was very simple.

Ye Tao naturally knew that even if this pile of things were implemented and deployed from now on, it would be impossible to put it into practical use without a few years. This time, it was just to allow the Intelligence Bureau to start training a group of talents and give them preliminary internship opportunities. This time, the most important thing would be the newly introduced recording technology.

Recording technology had been developed for several generations in the Ye's Workshop Research Institute, and now, it had finally shown relatively good performance in terms of reliability, ease of use, and so on. The earliest recording technology was the wax cylinder, although Ye's Workshop had reached a considerable level in precision machinery, but after all, it could not solve the defects of the material itself. The sound receiving end of the wax cylinder recorder used a paper cone, which did not involve circuits at all, but relied on an extremely thin probe to transmit the sound vibration sensed by the paper cone to a control box, which amplified a little dynamic, and portrayed this dynamic on a uniformly rotating wax cylinder. Although this thing could almost be called a display of precision machining technology, the recording effect was terrible. The recorded sound was blurry when played back, interfered with by noise, or could not work normally if the sound intensity fluctuated too much, and would leave a string of screams on the wax cylinder. In addition, the life of the wax cylinder was very short, and it would not work after playing it back a few times, which greatly reduced the practicality of this technology.

The second generation of recording technology was much better. The researchers in the electrical workshop of the research institute discovered the galvanizing effect of sound, and developed the first generation of mixed mineral sand sound probes, which had a very good effect. The collected sound was amplified and then firmly engraved on the shellac master disc. But this second generation of recording technology had a big problem, that was, the sound signal was amplified in the mechanical section, and the distortion was very serious. But after all, through this second-generation technology, the workshop already had basic ideas, master disc materials, sound probe technology, and even developed a technology for copying with master discs. Although the copied discs were always a little different from the master disc when playing back, the quality was becoming more and more stable and reliable.

At this time, Ye Tao decisively intervened in the research. For the sound probe, Ye Tao had nothing to change. This sound probe might be a little bigger, and the most exquisite prototype was as big as a microphone, but it was completely usable, and the accuracy was also very surprising. Ye Tao understood that the bottleneck of this recording equipment was that the researchers did not have the knowledge and experience of circuit design. And Ye Tao directly guided the basic transistor manufacturing, developed the first and second generations of transistors, and began to popularize the knowledge of circuit design. The third generation of recording equipment was born. In terms of sound collection and master disc engraving technology, although there were slight improvements, the third generation of recorders was generally developed along with the second generation, but there were earth-shaking changes in the middle part.

After the sound was collected and turned into an electrical signal, it was conducted to the master disc engraving mechanism after two layers of filtering and three levels of amplification. Although such a recorder was slightly larger, to accommodate many transistors, the design concept was already very mature. The recorded sound was only slightly distorted, but it was already possible to distinguish the speaker's voice, and the recorded animal sounds could also distinguish the specific types, which already had sufficient practical value. After the design concept matured, the researchers in the workshop quickly made various improvements in amazement. As the manufacturing process of transistors matured, the volume was reduced, and the cost was reduced, and as the researchers carried out shock absorption, reinforcement, and other designs on the recording device, the volume was controlled, and the disc engraving device was also improved, forming an integrated design of collection, processing, and engraving. The current recording device is probably the size of a two-foot square box. Moreover, those probes can be installed with wires to a distance from the recording box, and even, now the improved probes have a bit of directional sound collection effect. If it were put in the era of Ye Tao and Tan Weixin, if such a bloated thing was used for eavesdropping, it would probably be laughed at, and even roadside stalls would not be willing to sell this kind of thing. But, in this era, when the person being monitored is completely unprepared, this set of things is indeed a super weapon.
