"What, Gongjin, has there been news from Yizhou? Won't it be? Sun Ce asked, unable to maintain his composure any longer, and asked in disbelief.

Many people present were also shocked, what they were most afraid of was to hear that Jin Jue had captured Chengdu City, so that even if some places were not controlled by Jin Jue, the entire Yizhou had actually been decided.

And when the time comes, Jin Jue will have the time and opportunity to attack Jingzhou in the east, or Liangzhou and Sanfu in the north, both of which have a very big impact on Sun Ce's future plans.

Fortunately, Zhou Yu didn't sell it, and he quickly replied: "Don't worry, my lord, the news that came a few days ago was not the worst news that everyone was worried about happening. Zhao Wei, who previously occupied Yongning County, has been killed by his own generals, and his subordinates have already raised their entire army to Jin Jue's side. Let me ask you, in this case, do you dare to underestimate him? Dare to say unashamedly that the battle of Jiangbei is really just a small negligence on the part of you, me and everyone? ”

After listening to Zhou Yu's words, everyone couldn't help but gasp.

After the Battle of Jiangbei, Sun Ce had to start paying attention to Jin Jue and the collection of intelligence.

Therefore, he sent a lot of people to Jingzhou and Xuzhou, and more often through Jiangxia and Nanjun to enter Yizhou.

By now, the people in Sun Ce's army have basically understood the situation in the entire north-central region of Yizhou.

Of course, it was the information of the petty warlord Zhao Wei before he was defeated and died.

The spies sent by Sun Ce to Yizhou wanted to hide from Pang Xi, Zhao Yun and the barbarians, but they couldn't hide it from Li Hui and Zhang Ji at all, both of whom have now obtained the true inheritance of Jin Jue. According to the orders of these two Samba Taishou, as long as there were people with foreign accents in their territory, they would all be immediately arrested and sent to the copper mines in Jianwei County to work as miners.

Among the four counties in the south of Yizhou, there are many peaks and hills, but there are few flat lands, and there are relatively few Han people who settle here, and correspondingly, there are many precious metal mines in these four counties.

For Jin Jue, copper ore is naturally important, and in the Han Dynasty, copper was the most important monetary metal. Although Jin Jue has thought of a lot of good prescriptions for monetary reform, he does not want to change this status quo for the time being until the whole world is unified.

Therefore, the princes of the world sent people to infiltrate Yizhou's fine work, and almost all the troops were wiped out.

Of course, in addition to Zhou Yu.

Zhou Yu was the first person in Sun Ce's army to send fine work to Yizhou to investigate the situation of Jin Jue's army, but at the beginning, the fine work he sent was also wiped out. At that time, Li Huidu had not yet joined Jin Jue's command, and the task of capturing foreign details was all done by the dynasty.

After Zhou Yu found that the fine work he sent to Yizhou had disappeared from the control of Jin Jue's army twice in a row, he had already realized that Jin Jue must have a very effective method for investigating spies.

After thinking about it, Zhou Yu recruited a child of a family from Yuzhang County who had to move his family from Yizhou to Yuzhang County because he offended Liu Yan in the last years of Emperor Ling, and had to move his family from Yizhou to Yuzhang County.

After Zhou Yu learned the detailed information, he was convinced and admired by Jin Jue.

In this era, who would have thought that just by relying on the accent, they could find out the spies sent by various forces?

"Oh! Gong Jin, in this way, has our army used this method to investigate the spies sent by other forces in Jiangdong? After listening to Zhou Yu's explanation, Sun Ce's eyes flashed and asked.

"I'm afraid not." Unexpectedly, Zhou Yu shook his head and replied: "Lord, first of all, there are many people from various states in Jiangbei who have crossed the river to escape the war and settled in Jiangnan.

The situation in Yizhou is different from our Yangzhou. Liu Yan and Liu Zhang moved most of the people who fled from Nanyang County and Guanzhong to Yizhou to live in Chengdu, and there were very few scattered in the counties and townships. According to the report of the subordinate sent to Yizhou, Jin Jue ordered a general from Guanzhong to deal with this matter from the very beginning, and he concentrated all the people of Guanzhong and Nanyang County scattered in various counties and townships to Luo County.

Jin Jue therefore issued an order, and anyone from Guanzhong or Nanyang County who left Luo County without permission was a spy.

Of course, my lord, it is not difficult to investigate most of the spies who want to listen to the secrets of our army, and in the future, all those who are not in the army and speak with foreign accents will all be punished as spies, and the matter can be handled by the assassins in each army. ”

At the end of the Eastern Han Dynasty, in order to avoid the successive wars, Jingzhou, Yizhou and Yangzhou all encountered this situation where a large number of people from other states fled to the territory, but because of Liu Zhang and Liu Yan, only Yizhou could completely clean up the spies.

The solution proposed by Zhou Yu has many drawbacks, and if the people who investigate the spies have selfish intentions, it is very likely to cause unjust, false and wrongful cases. However, in the current situation, it is not an extremely effective approach.

It is possible to prevent the spies sent by all parties from the source as effectively as possible to investigate Sun Cejun's actions.

However, Zhou Yu may not know that the solution he proposed is very difficult to catch the spy who was really sent by Jin Jue.

Jin Jue is not a fool, as a traverser, when he was training spies, he repeatedly emphasized that if you want to detect the movements of the enemy army, it is best not to have direct contact with the local army.

Or spend money to buy some very bold people such as ruffians and hooligans, and let them take the risk to probe the news, so as to avoid being discovered by the enemy because of the accent problem; It can also prevent your own people from being sent to death.

Or learn about the enemy's movements from the side.

In ancient times, it was never easy for a dynasty or warlord army in the Chinese region to go on a campaign.

When the army goes out on the expedition, it has to recruit troops, collect grain and grass, all kinds of baggage, oxen, horses, carts, etc., anyway, it has to prepare a lot of things, and then, on the way to the march, it is inevitable to collect some military supplies from the local area.

Therefore, the spies sent by Jin Jue to the territory of various forces, they only need to use these side intelligence, there is a great chance that they can predict the specific movements of the enemy army very early in advance.

Of course, this method of probing intelligence is not a one-size-fits-all method, it is absolutely accurate, and it will definitely work.
