Because of the warm current of the North Atlantic, and the fact that it was sailing on the prevailing westerly wind belt, the fleet had a smooth journey and approached the mainland in a few months.

However, Marin did not land directly at Emden, but first went to the Wilhelm military port in the north of Oldenburg province with four 250-class armed merchant ships. It is inaccessible and is a very hidden military port, where merchant ships and fishing boats are not allowed to approach in normal times, and a cordon is also set up on land, and ordinary people are strictly prohibited from crossing the line.

Marin was very cautious and did not know what was going on in the native land. In order to avoid a drastic change in the country, he first sent a ship to Wilhelmshaven to hear the news, and after discovering that there was no coup d'état in the North Sea State, the ship waved the flag to Marin's ship - everything was safe.

Only then did Marin dock with the remaining three boats. Moreover, he landed in the evening. And the commander of the naval fleet in Wilhelmshaven, Scheer, also transferred the ordinary sailors according to the order, leaving only a small number of cronies to greet Marin to avoid the leakage of information.

When they landed, Marin and his men were all dressed in black cloaks, revealing their hidden identities. It was only after entering the interior of the naval headquarters in Wilhelmshaven that Marin and Kahn took off their cloaks.

After dinner, Marin sat down at the table, smoking a homemade cigarette, and asked:

"Tell me, what has happened in China in the past two years?"

Scheer thought for a moment and said:

"It's a lot going on, and the first year you left, the country was calm and nothing happened. However, from the second year onwards, some people began to spread rumors that you had died in the sea......"

"Hehe......" Marin sneered, not surprising about this.

After a few more puffs of cigarette, Marin continued to ask:

"Who's bouncing?"

"Mainly, the frustrated old aristocrats of Bremen are dancing happily, but they are not much of a threat. I have heard that some German princes secretly sent people to co-opt the generals in the army...... Even, there may be France involved......"

Marin was shocked......

Those frustrated aristocrats are just like Scheer said, even if they make trouble, they can't become the climate. However, if someone reaches out to his army, that is a big deal.

You know, most of Marin's army was recruited from the mountains of southern Germany, and he was not a native of his own. Although Marin treated them well and gave them good treatment, that was when Marin was still there.

However, under the influence of the rumor that "Marin has died in the sea", it is difficult to guarantee that someone will have a floating mind......

So, Marin asked Sher to send someone to contact Kohler overnight and ask Kohler to come to Wilhelmshaven. By the way, Scheer was also an intelligence officer under Kohler before, and it was only because he had been a captain and had experience in naval battles that he was transferred to Wilhelmshaven by Marin. So, it was easy for Scheer's people to contact Kohler.

Kohler arrived early the next morning after receiving the news, and brought with him another intelligence chief, Sauer, one of Marin's men. Both were intelligence chiefs, but Kohler was primarily responsible for foreign intelligence gathering and civilian intelligence gathering, while Sauer was primarily responsible for spying on the military and officials.

Because they knew that Marin wanted to keep it secret, they both came over on horseback after putting on makeup and pretending to be ordinary messengers.

After seeing Marin, both of them excitedly rushed up and hugged Marin. Of course, Kohler doesn't forget his big brother Karn either.

Seeing this, Marin first asked Kohler and Karn to tell him about their brother's parting, and then summoned Sauer in the secret room. In fact, he was also worried that the two would deceive him in tandem and ask questions separately, which would make him more at ease.

"Is the army okay?" Marlin came up and went straight to the point. He didn't even bother to ask the officials questions, because if the army was stable, it was stronger than anything else. After all, grandpa Tai said that power comes out of the barrel of a gun. Even during that very chaotic decade, there were no major problems with the military. Otherwise, it would have collapsed long ago.

Sauer frowned and said:

"According to the intelligence officers' investigation, it seems that some of the wandering knights who took refuge in you in the first place were shaken after hearing the rumors of your accident. In the past year, many middle-level officers from the wandering knight family have been secretly contacted by outsiders......"

"Is there a leak problem? I mean, the issue of agriculture. You know, the secret of high agricultural yields, but the foundation of the Beihai Kingdom......"

"Probably...... There may be some leaks......" Sauer hesitated.

"Partial leaks? How? Marin didn't understand.

Sauer explains:

"That's right, our high-ranking generals have basically not wavered, but a small number of unsatisfactory middle-level officers and some low-level officers may have a tendency to leak secrets. For example, the secrets of high agricultural yields that you value have been revealed to the outside world. However, those mid- and low-ranking officers who are not satisfied with the mix do not know much about the secrets of high agricultural yields, and only know that we have a special fertilizer that can make the land more productive. But the problem is that they don't know the exact formula of the fertilizer......"

"Hehe......" Marin laughed. At the beginning, he specially built a fertilizer farm to collect manure for centralized treatment, and specially required that the manure must be fermented and air-dried for several months to make the odor as low as possible. Therefore, even if many people have seen fertilizer, they may not be aware that there is feces in it.

In addition, the sources of apatite and potash, only a few of the most reliable people, such as Kohler, know the source. Even cronies like Kohler only know about potash, not apatite. Because the potash mine was bought by someone sent by Kohler. As for the apatite mine in Laayoune in Western Sahara, Marin was sent by another person.

Therefore, in the entire Beihai country, few people know all three kinds of specific components of compound fertilizers. Even cronies like Kohler know that there are two kinds of feces and potash. However, they also know the secret that fish bones and fish guts can replace apatite. The reason why Marlin used apatite instead of fish bones and fish guts was to keep it confidential. After all, in all of Europe, no one knows what apatite is, except for Marin and his cronies......

"So, those who are betrayed are asking around about the composition of fertilizer?"

Sauer nodded:

"Yes, it was because they were inquiring about the composition of the fertilizer that our spies caught the clues and targeted the ......"

"How did you deal with it?"

"It's still being studied...... Mainly, Schwartz believes that in your absence, the priority is stability, and conflicts with other countries should be avoided as much as possible...... After all, if we find out the heads of some princes, we can't just do it......"

Marin nodded, Schwartz was right. I did not think about it when I left the country, mainly because I had seen too much in the Ming Dynasty in my previous life, and I had a very heavy Ming Dynasty plot in my heart, so I ran to the Ming Dynasty irrationally to take a look.

If you are not there, it is equivalent to having no owner of the country, and you must be panicked. In addition, some people maliciously spread rumors, which is indeed not suitable for turning their faces with others.

Fortunately, because he did a good job of secrecy at the beginning, he did not let the enemy completely succeed. After all, the human heart is greedy. Those middle- and lower-level officers who are distracted will definitely not be willing to get a complete fertilizer formula. After all, a complete fertilizer recipe is a very good name. If you take this kind of petition to join other princes, you will definitely be reused.

When Kohler and Karn had come in after talking about their brotherhood, Marin commanded:

"Mobilize all the spies and concentrate on the leakage of agricultural secrets. In addition, organize killers and be ready to assassinate nobles from other countries who have obtained some secrets, even if they are princes......" Marin said murderously.
