1995, Starting as a Criminal Investigation Expert

Unexpectedly, after Li Shu and Ji Chunyang went downstairs, they discovered that Yue Changlin had not left by car.

He beckoned to Li Shu and waited for Li Shu to come forward before saying, "Li Shu, I forgot to ask. You mentioned before that we need to do our own fluorophore testing, which involves testing for drugs in the sewers and creating a DNA database. Is that the term you're referring to?"

Seeing Li Shu nod in confirmation, he then asked how things were progressing.

Li Shu reported last time that he only had this idea, but whether it could be implemented was still unknown.

Li explained the situation.

Since Sun Bomin had taken over the task of testing for toxic substances in the sewers, Li Shu felt he had an 80-90% chance of success.

The reason for reducing it by one or two percent is to prevent any problems from arising during actual verification; we cannot make any definitive statements.

"As for fluorescence profiling, Director Yue, we've visited quite a few research institutes these past few days. As you know, almost no one in China is researching this technology. We can say we're starting from scratch."

"I am organizing people to conduct a nationwide survey to get a clear picture of the situation both domestically and internationally before considering how to proceed."

For something this big, research is definitely necessary.

Yue Changlin nodded slightly and then inquired about the progress of the automatic na extraction equipment.

After learning that everything went smoothly, he nodded in satisfaction, pondered for a moment, and said, "I see. Next year is a crucial year. I have two things to tell you."

"The first thing is police equipment. You should know that the general direction from above has always been to focus on developing and combining technology with criminal investigation, emphasizing technological capabilities."

Once he started talking about serious matters, he got into the boss mode.

However, Li Shu listened very carefully. Don't think it's empty talk; this is the general direction, the strategy.

Yue Changlin continued, "You may not know this, but the earliest police equipment ordering exhibition was held in Nanjiang in 87. Another one was held in Anjing the following year. Many police technologies were introduced at that time."

Li Shu was completely unaware of this situation, and even less expected that Nanjiang was involved.

In fact, Nanjiang has made a significant contribution to the development of criminal technology.

"In the past two years, criminal investigation technology has been shifting from manual to automated processes, and thanks to you, a large number of technological achievements have emerged."

"The ministry's intention has always been to engage in exchanges with foreign countries, go global, and achieve win-win cooperation. So we're considering taking advantage of your NA automatic extraction equipment and Hong Kong's plan to purchase a gun and ammunition comparison system to hold another exhibition in the form of a trade fair."

"We extend invitations to countries around the world, as well as to provinces and cities within our own borders, so that they can come and visit. We can showcase the new technologies from your two institutes and one institute, and see if we can make a name for ourselves in the future."

"You two institutes need to take the lead in this matter, produce a batch of results, and get ready. Once you're ready, we can discuss the specific timing later, but we'll put it in the first half of next year."

Li Shu hurriedly said, "Director Yue, this is a good thing!"

Li Shuzhen felt like someone had delivered a pillow to someone who was about to fall asleep. He was planning to sell the automatic na extractor for more money and foreign exchange to raise funds for his research and development of fluorescence typing.

So, this kind of trade fair, which can invite foreign police officers and manufacturers, is the best opportunity.

:

Li Shu then asked about the second matter.

Yue Changlin said, "The ministry plans to hold a national criminal investigation work conference in the middle of next year. It's very important. First, it will be to summarize the results of this year's crackdown."

"Secondly, we need to deepen the reform of the criminal investigation system. The specifics of how to reform are still under investigation and research, but the direction is clear: reform is imperative."

For example, merging criminal investigation and preliminary hearing, or extending criminal investigation resources to the grassroots level instead of always concentrating them in counties and cities.

"This is a big deal. The minister specifically asked you to attend and give a report, focusing on the field of criminal technology."

Among criminal investigation professionals nationwide, Li Shu may be young, but he has risen to prominence the fastest, possesses the most comprehensive technical skills, achieved the greatest results, and has rich experience in handling cases. He is always on the front lines, able to combine technical expertise with practical case handling.

Looking across the entire country, it can be said to be unique.

Therefore, the ministry specifically requested that Li Shu participate.

Li Shu nodded, inwardly shocked. He realized he had truly made it big, being able to attend a meeting of this caliber.

Yue Changlin continued, "There are still six months left, so you must take it seriously and prepare well."

Li Shu nodded, several thoughts suddenly popping into his mind.

It was also last year that Li Shu had this idea, and at the time he even considered bringing it out when he graduated from public university and defended his thesis.

Who would have thought I would improve so quickly and have such a better opportunity to make my voice heard?

"Director Yue, rest assured, I will make proper preparations for this matter," Li Shu said.

Even now, Li Shu has already figured out the direction.

These ideas are the result of years of dedicated study of technology, practical case handling, and reflections on my work.

There are only three.

Nationwide police network, cameras, and new generation ID cards.

Li Shu believes that these three points are the most crucial and useful for improving public security.

The next day, Li Shuxian talked to Liu Yaoqing about the trade fair.

After they finished talking, they pulled Bao Yun and Wang Ze'an aside for a short meeting.

The exhibition is not just about high-end equipment; technologies in the field of fingerprint extraction can also be exhibited as achievements.

For example, indanedione, vacuum coating, and these three methods.

In addition, various fingerprint extraction methods used in case handling, such as P, 502 wet stickers, etc., are all acceptable.

After the conversation, Li Shu organized his thoughts and made a timetable.

:

The NA automatic extraction instrument, with 24 channels, is working flawlessly and should be completed next month. If all goes well, the review and acceptance can be conducted by the end of January.

Li Shu needs to prepare for this.

As for doubling it, the 48-channel version, Lin Fusheng and his team thought about it and the feedback was that it was hopeful, but quite difficult, and it probably couldn't be done in a short time.

If they were to test for drugs through the sewers, Li Shupan estimated it would take until the end of January.

Before the new year, we'll see if we can collaborate with major cities like Ankyo, Songpu, and Yangcheng to conduct a test.

Only large cities have well-developed sewer networks, and with their developed economies, there are many drug addicts.

As for fluorescence typing, that can only be postponed. Let's start doing the preliminary research first.

Li Shu planned to spend two or three months completing the research and preparation work.

Once the trade fair is successful and the funding is secured, we'll begin immediately.

It's already 97, we really can't keep putting it off any longer.

Some of the key equipment that we are developing, such as the capillary electrophoresis apparatus, can be ordered at the trade fair.

Therefore, Li Shu planned to schedule the trade fair after the Spring Festival, in March.

The timing is most suitable.

After some further deliberation, Li Shu decided to add video processing to the project as well.

It involves not only multi-frame super-resolution reconstruction, but also single-frame image processing.

Regarding single-frame processing, Li Shu had reviewed the system documentation and knew that TV denoising, or more accurately, TV total variational regularization restoration, was a landmark and far-reaching technology in single-frame image processing.

Now that we know the future direction of development, we should avoid detours and head straight for the key technological milestones.

This is something that foreign countries have only just begun to research. If we take the lead and do it first, we can also be at the forefront of the world.

If the trade fair is scheduled for March, Li Shu feels he has three months to complete the entire process.

In this regard, I can start by cooperating with Wei Ranhui and the others.

Because I'll definitely have to bring up the issue of cameras at future criminal investigation technology conferences.

If this technology proves successful, the camera's performance will be significantly enhanced, essentially serving as a foundation for future technologies.

Furthermore, the entire algorithm can be developed into software, and even used to create one's own image workstation.

Image workstations are just as expensive.

:

Even if we just sell the software, this thing has such a wide range of applications, just selling the software might be enough to raise the research and development funds we need.

After making his decision, Li Shu went out to find Wei Ranhui.

I plan to invite him along to Peking University to find Geng Zheng.

He can't solve the mathematical problems, but for practical implementation, he, as a computer expert, is needed to handle the coordination.

"Director Li is here."

As soon as we entered, everyone was incredibly polite.

They greeted us from one side, and then invited us to make tea from the other.

After yesterday's class, the research papers for the Computer Applications Department for the next year or two are now secured.

In their eyes today, Li Shu is, without exaggeration, their benefactor.

"No need, you guys are busy."

Li Shu waved his hand, and when he found Wei Ranhui, Wei Ranhui was teaching Chen Yan how to use the search system.

Chen Yan listened very attentively. Every minute wasted on something unfamiliar was money, especially foreign exchange.

Li Shu greeted them, called Wei Ranhui, and left.

Upon hearing about the new algorithm for single-frame image processing, Wei Ranhui wasn't just interested, he was excited. As soon as he got on the elevator, he slapped his forehead and said, "It wouldn't be appropriate to go empty-handed."

He then said he was going back to his department to get it.

He manages the search system, so there's no shortage of gifts like tea.

Li Shu grabbed him, shook the bag, and said, "I've prepared everything. Besides, believe it or not, even if we go empty-handed, they'll still treat us to a meal, a big meal."

In the past, I was the one who submitted research projects and papers.

Wei Ranhui looked surprised, but thinking about what happened yesterday, he realized that Li Shu was not bragging.

Just like myself, when Li Shugang asked for ten thousand US dollars, I was really in a dilemma.

After finishing the lecture, he regretted that the more than 20,000 US dollars were not enough, and wished he could give all of it to Li Shu.

The two went downstairs. Wei Ranhui was about to push his bicycle when Li Shu stopped him, went straight to the roadside, and opened the door of the car parked there.

After learning that the ministry had assigned someone to protect him, Li Shu realized that it was a waste to have them follow him in a car while he rode a bicycle in front of them.

Let's just get in their car and call it a day.

It's all done in one go, including the car.

:

"Go to Peking University."

Li explained the destination.

Wei Ranhui, who got into the car, was a little stunned and wanted to ask Li Shu when the institute had assigned him a private car.

It was the same two people, Lao Zhou and Xiao Chen.

Without asking any further questions, he immediately drove off and headed straight for Peking University.
