Although the intelligence system of the Qin State has set up a secret department. But the ability to gather intelligence has dropped a lot. The main reason is: There is a lot of economic intelligence and information processing. The superposition of military, political, diplomatic, and economic information makes intelligence officers feel very tricky. In particular, economic intelligence. This was a headache for those who were accustomed to gathering military, diplomatic, political, and some economic intelligence.

Qin's military campaign against the Kwantung region largely stopped. It is precisely because it has basically stopped, and the responsibility of the intelligence system is very large. In particular, the collection, analysis, and collation of economic information. So that the intelligence officers do not understand. They simply don't know the rules of business conduct. It's very difficult to do.

In addition, the economic development of the Qin State was very rapid. Business activities are becoming more and more frequent, and there are more exchanges. The amount of information produced has swelled.

For example, Qin wants to collect economic data from South Korea, his transportation capacity. Road conditions. There are also coal mines and iron in Zhao State, these are very common, and in the eyes of intelligence officers, there is no difference. Especially coal. But in fact they were wrong. An inadvertent inquiry. Only then did they know that there were as many as 10 types of coal. The coal produced by Zhao Yunzhong and Daidi is of the best quality. The direct combustion of coal in the northern part of the Qin State will release a large amount of sulfur-containing substances. It is this distinction. The demand for coal from Qin to Zhao increased greatly.

The intelligence officers couldn't think of it first. There is such a big difference between coal. In fact. This also illustrates. Qin's intelligence system needed to be overhauled. Especially technically. Competent technicians need to provide reliable technical support. Then the interpretation is carried out. These professionals are prioritized for commercial use. The problem is funding. Funding for the intelligence system is insufficient to support technical support.

It's not just technology. There is also the expansion of personnel and the system of intelligence networks. If in the past, Qin's spy network would not have expanded so much. At most, they are expanding in the major cities of a country. Definitely not very large.

But this time it was different. Rapid economic development, especially the establishment of new transportation. In some road junctions and junctions, there are a large number of small towns and small cities that should not appear. The people of these cities communicate very quickly. There is a lot of information to be updated. It can be said that a waiter knows more than what is reported in the newspaper. A lot of strange things continue to appear, and the appearance of Shangwen stimulates people's nerves.

The geographical area should be expanded, from the original few to more than hundreds. These areas are more than necessary to send manpower. Because each of these regions has its own characteristics. The town of Yan is more related to the Qin-Yan trade. Zhao Guo is mostly related to coal mines. There must be an intelligence system in these areas.

It's not just geography. There's also a lot of information. This information is updated very quickly. And often the details of an event are present. Extrapolating from the details to the extension. The pressure on intelligence interpretation has increased.

There are various reasons above. As a result, Qin's intelligence entered a state of paralysis in its self-development. This state of paralysis made the Qin State automatically ignore the actions of the Yan State. This is also the reason why the intelligence system of the Qin State did not react after the Yan State possessed the chemical poison gas. Ultimately. It's moving too fast. A lot of things are constantly intertwined and changing, both active and passive. And the intelligence system turned out to be much slower. This is a huge gap in thinking and understanding.

That is now changing. Feng Zai served as the leader of Qin's intelligence system organization in Yan. He looked through all the intel. It was found to be very cluttered. And there's no conditioning at all.

Feng Zao not only thought he was a new soldier, but he also received a more systematic university life. He studied physics, chemistry, and primitive philosophy. Maybe it's because the learning is too extensive. He also dabbles in biology, medicine, and especially news gathering. This made him academically unsophisticated. He didn't make a mark on his line. But it is such a person who is proficient in everything that is precisely the one who is most needed by the intelligence system.

Feng Zai visited all the intelligence points set up by the Qin State. He found that the level of chaos was worse than he had imagined. Afterwards. He put forward his opinion. Having studied mathematics, he began to classify according to his own ideas.

Intelligence stations were set up in major cities in Yan Kingdom. Start with the center of the site and draw an area for intelligence gathering. Below the primary sites are the secondary sites for each town. The first-level site collects and summarizes the second-level site and reports to the highest site. This is the initial establishment of an intelligence network.

In the details. He changed the professional practices of the Qin State. Instead, the merchants of the Qin State were used as cover. Itinerant merchants. and fixed hotels became the main source of intelligence. This is not only a cover. There are also some sources of income. This allowed the intelligence network to grow rapidly. On personnel. The intelligence post absorbed a large number of local idlers. Most of these people talk about curious things. This inadvertently lightened the burden of intelligence gathering for the Qin State. Strange things are well documented.

At the time of the debriefing. The site is to be summarized. And there is a one-line connection between them. In this way, the degree of secrecy suddenly increased. Feng Zai's ascension to office partially changed the state of Qin's intelligence paralysis in a short period of time. This also allowed the chemical gas to gradually surface.

In a report on the topic of local conversation. A piece of information is divided. Yan imported a large number of unidentified cylinders from Qin.

This caught Feng Zheng's attention. To know. Steel can be an extremely important strategic resource during this period. He can be used to make a large number of weapons. And. Or gas cylinders. This type of steel is a special type of steel than ordinary steel. This made Feng Zai vaguely feel that there was a problem.

The information goes through a lot of processing and subsequent processing. Cylinder uses are starting to surface. A royal guard had seen the cylinders when he was ordered to dispose of some of the corpses.

Corpses, gas cylinders. Why do two unrelated things appear at the same time? What's inside the cylinder is key. The subsequent investigation gave Feng Zai an idea. Chlorine. A lethal poison gas.

A comprehensive report on the frontline status of the Yan State. Feng Zheng boldly wrote a conjectural report. Yan Guo then used chemical gas. Please pay close attention to the Qin State.

In order to have conclusive evidence. Feng Zai began to order people to collect relevant information. Especially the situation on the battlefield. Meantime. He also demanded that Qin pay attention to the control of chemical poison gases in China. Because there must be a reason for the loss of this thing. Although there is no specific incident to prove it. But such unregulation is not a wise move.

With a little bit of chemistry. For the first time, Feng Zheng proposed the idea of chemical gas warfare. And asked the Qin military to revise the definition of weapons. Requires the concept of expanding weapons. Because many civilian things and weapons have only one purpose difference.
