There is no doubt that intelligence gathering is a very difficult thing to do, both in ancient times and in modern times.

That's why every time there is an intelligence agent with a high success rate, he will be so famous, so that the world will remember his contribution to his own country and the harm he has caused to other countries.

Many well-known figures have invariably told their opinions about intelligence agents, and some even say that they alone are enough to be worthy of a recompiler.

It is also true that intelligence spies who have completed their tasks perfectly have brought even more benefits to the country than a reorganized division has brought to the country on the battlefield.

Therefore, Xiao Ruxun took great pains to set up Heishui, so that Heishui was full of secret agents at home and abroad, dealing with people who wanted to be unfavorable to Daqin, and by the way, exploring the topography and mineral deposits of neighboring countries, as well as the degree of wealth, as well as the military, political and economic situation, and doing enough understanding of neighboring countries.

With the development of Blackwater and the development of the relationship between Daqin and Europe, Xiao Ruxun even arranged teams of Blackwater agents on merchant ships going to Europe, and even some caravans were composed of Blackwater spies at all, and Xiao Ruxun needed them to collect intelligence everywhere for his own use.

In order to make their activities better, the largest expenditure in Xiao Ruxun's internal funds is Heishui's, and only 30% of Heishui's activity funds go to the accounts of the national treasury, which are above board, and the remaining 70% are Xiao Ruxun's internal expenditures, which are the shadows of darkness and specialize in doing unsightly things.

Correspondingly, in order to better serve himself, Xiao Ruxun set up a black duck to supervise the treatment of black water, and the black bird has two major responsibilities, one is to supervise and deal with officials, and the other is to supervise and deal with black water, which is specifically aimed at the personnel in the Great Qin organization, and is not responsible for targeting ordinary people and foreigners.

The Central Investigation Department, which uses the black plover as the source of manpower, is the identity of the black plover's official face, which is known to the officials of Daqin, and there are very few people in the Daqin government who really know the existence of the black plover, and only a few people know about it.

Xiao Ruxun also paid 70% of the black bird's expenses, so he opened up mineral deposits extensively, nationalized metal mines, and sent people abroad to find mines to enrich his internal funds.

The emperor must maintain a certain degree of economic independence and economic expenditure, otherwise it will not be enough to guarantee his power.

Rao is like this, with hundreds of thousands of silver expenditures every year, the valuable and effective information that Xiao Ruxun can get is only about 123% of the total amount of intelligence, and the remaining 80% or so is useless information.

However, even the real value behind this 123 percent of the valuable information is far more than hundreds of thousands of taels of silver.

It's like Xiao Ruxun's full support for Heishui, which led Heishui to set up several spy teams to deal with those domestic and foreign intelligence agents in Daqin who are targeting Daqin, who are often active in the most densely populated places in big cities, collecting all kinds of intelligence.

Xiao Ruxun asked Heishui to vigorously crack down on these intelligence officers, and the most caught were the Japanese, in Nanjing, Suzhou, Hangzhou, and Ningbo, Heishui smashed seventeen or eighteen Japanese intelligence organizations one after another, and after interrogation, most of them were arranged by the Tokugawa clan, and a few were from the Toyotomi clan.

After clearing this group of people, Xiao Ruxun ordered his intelligence officers to be more vigilant, especially to conduct a carpet search in the Weigang area of Tianjin, which was preparing to send troops, to eliminate all hidden dangers, so that the Japanese would become blind and unable to know about Daqin's military operations in advance.

At this time, even if the spy gets the information, it is still a difficult thing to send it back to China, instead of using electronic communication technology to instantly transmit it back to China as in modern times, which does not exist, and it must be carried by people and travel across the ocean for half a month to a month before the intelligence can be sent back.

And during this period, the Great Qin army had already landed and started fighting, and even if the Tokugawa clan and the Toyotomi clan learned about it, they could not do anything, and they had no time.

On April 11, Shiba Kunizhu began to attack Kyushu Island, and under the guidance of the secret agent guide, he successfully avoided the traps and traps set by the Tokugawa clan and launched an attack on the city.

It was not until the 12th, when the main force of the Mawei Division set sail, that the information of the Tokugawa clan was delivered to Tokugawa Ieyasu, who was fighting continuously between Iwami and the Toyotomi clan, and when Tokugawa Ieyasu learned of this information, he was commanding a battle with the Toyotomi clan army for the commanding heights and arranged gunners.

Each side of the battle sent their strongest generals and strongest armies, and under the respective plans of Ishida Mitsunari and Tokugawa Ieyasu, they went head-to-head on the battlefield, and neither side was willing to retreat, and the commanding heights were surrendered.

Toyotomi Hideji dispatched a powerful daimyo led by Ukita Hideya to lead their respective elites to launch a powerful attack on Tokugawa Ieyasu, and Tokugawa Ieyasu, who was inferior in numbers, repeatedly encountered difficulties and dangers, but was suppressed by him with a resolute attack.

This battle has been fought for three hours and has not yet been decided, and the casualties on both sides have reached thousands, and counting the casualties of these ten days, at least more than 10,000 people have been killed in the Toyotomi clan, and nearly 8,000 people have been killed in the Tokugawa clan, and there will only be more wounded.

In such a situation, the strength of the two sides is really strong, and there are few external factors, and Ishida Mitsunari's plan makes Tokugawa Ieyasu feel that it is difficult to move an inch.

It turns out that Toyotomi Hideji still has some ability, and he can actually reconcile the contradictions between the Ishida clan and the military generals faction, and let them work together to deal with themselves.

Tokugawa Ieyasu realized that Toyotomi Shuji was not a simple character.

It is no wonder that Toyotomi Hideyoshi chose Toyotomi Hideji as Sekihaku to take his place at that time.

But the matter has come to this, Tokugawa Ieyasu has no possibility of retreating, this battle must be fought to the end, can not retreat, once retreated, the result should not be too miserable.

At this moment, when Tokugawa Ieyasu commanded a thousand-man team and the Toyotomi army to desperately compete for the commanding heights, the artillery of the Toyotomi army and the Tokugawa army were also firing at each other, but at this time, Tokugawa Ieyasu received information that the Qin army set sail from Korea and aimed at Japan.

At that moment, Tokugawa Ieyasu felt that his heart was about to stop beating.

No way? It can't be like this, right?

How could the State of Qin do such a thing?

How could they do such a thing?

How could they have the power to do such a thing?

All kinds of questions lingered in Tokugawa Ieyasu's mind, so much so that Tokugawa Ieyasu didn't react when his subordinates came to ask for reinforcements.

It wasn't until he shouted again and again that Tokugawa Ieyasu came back to his senses and realized that he was on the battlefield.

"My lord, Toyotomi has increased his troops again, we don't have enough manpower, ask for reinforcements!"

Tokugawa Ieyasu opened his mouth, and the words that he should have sent reinforcements to continue to fight for the commanding heights could not be said in any way.

Judging by the time, it may be too late.

No, you can't keep fighting, if you go on like this, it'll be over.

Tokugawa Ieyasu thought so.
