Hokkaido, a first-level administrative region in Japan, is located at the northernmost end of Japan.

It consists of Hokkaido Island and nearby small islands such as Rishiri Island, Reifun Island, and Okurijiri Island, accounting for about 22% of Japan's land area.

The forest cover area accounts for more than 70% of its total area, with extremely low population density, a cold climate throughout the year and a long winter.

Hokkaido is one of Japan's tourist attractions and one of Japan's grain bases. Its wheat, potato, soybean, dairy cow and milk production ranks among the top in Japan, its wood production and fishing volume rank first in Japan, and its mineral resources are abundant, making it the most important coal production in Japan.

When Chu Yan and Fenghuang arrived at Hokkaido, they felt a chill as soon as they got off the bus. This is the coldest place in Japan, and it is often flooded by heavy snow in winter. Therefore, there are many lamp poles standing on the side of the road here, and the height is marked under the lamp poles. The reason is that the snow here is too heavy and sometimes it will flood people. The highest record in history is four meters, which is a very terrifying number.

But there is no doubt that this place is beautiful, because of the extremely sparse population density, the original ecological environment here has almost not been damaged. Of course, the nuclear weapon test stations located at sea are also some distance away from here.

Sapporo is the first stop for Chu Yan and Phoenix, because according to reliable information, the Yamamoto family's base will be on the sea, and it will be a super huge cruise ship, but this cruise ship has never used the Yamamoto family's dedicated port.

Sapporo is the closest city in Hokkaido to the Yamamoto family's private port, so Chu Yan and Phoenix chose this place as their destination, and the hotel did not choose a high-end star hotel, they chose a hot spring hotel.

It is very quiet and the environment is very beautiful.

"Yanshi, this is indeed a holy place for vacation. I have always wanted to find an opportunity to come here and stay here for a while. Now I finally got my wish." After parking the car, Fenghuang and Chu Yan got out of the car and walked into the hot spring hotel.

Regarding Phoenix's words, Chu Yan smiled and nodded in agreement: "Indeed, this place is beautiful, but unfortunately we are destined to stay here for a short time. After all, we are here. Compared with the Yamamoto family, we are here to do bad things, so we are ready to evacuate before completing the task. This is what we must do.

I don't want to lose our lives because of a small mistake." Chu Yan and Fenghuang walked into the hotel with a smile, opened a hot spring suite, and then walked into the room together.

The so-called hot spring suite refers to a room similar to a wooden house villa. There are hot springs outside the room. After some rest and decoration, the hot springs become one of the rooms. You can rest and soak in hot springs. If you can take a break here for a few days in your life, it is definitely a rare blessing.

"You are so disappointed. I'll go to the hot spring first. I don't mind you taking a bath together." Fenghuang was a little unhappy with Chu Yan's attitude of doing business. After all, the place in front of her is really not suitable for business. Just a simple vacation, taking a hot spring is more suitable for here.

Phoenix ignored Chu Yan, threw down his coat and ran to the hot spring. Chu Yan took out his phone to contact Tianying and confirmed all the information that should be confirmed. In addition, after contacting Xuehe, after secretly arriving at Hokkaido, he directly found a way to find out the situation of the Yamamoto family's dock. Fortunately, he would secretly assist Chu Yan and Fenghuang in completing this task.

The time for hot spring bathing is always short. When the sun shines on Hokkaido the next afternoon, although the sky is clear, there are crowds of people on the beach in Sapporo and above the Yamamoto family’s private docks. One car after another appears on the dock. Every person who gets off the car has a gloomy face, which is not at all in harmony with the clear weather.

Chu Yan and Fenghuang were standing in the distance, observing the situation at the dock. Of course, telescopes were essential. After all, this is a private territory and a huge creature like the Yamamoto family, so basically it is considered that no one should enter.

"Phoenix, look at that guy, he seems to be in a good mood. But I don't know if he can still smile after the sun rises tomorrow." Chu Yan pointed to Kojiro Yamamoto who had just gotten out of the car. Although he was wearing a cast on his right hand, it did not affect his mood at all. Compared to the clouds of others, his face was much sunny.

Three people followed Yamamoto Kojiro, Qingchuan Noshita, Yamamoto Lingya and the unknown Kogaru master who was invited by Qingchuan Noshita for a large sum of money.

Speaking of the Kaga Ruo Ninja School, Chu Yan had to think of those extremely mysterious ninja villages in Japan. During the period when Japanese ninjas were the most prosperous, there were at least 30 schools in Japan, but the strongest ones were Koga and Iga.

These two schools are basically the mainstay of the ninja genre, so they are widely known. As for some other small ninja genres, there are very few people who know them.

"Rock, the person who follows Yamamoto Kojiro is not dressed like a samurai, he is more like a real ninja. We should pay more attention. After all, Japanese ninjas have too many strange things. Although I am very unhappy with ninjas, I have to admit that they do have magical features." Phoenix's gaze was directly positioned on Yamamoto Kojiro by Chu Yan's words, and he gave his own judgment on the thin but relaxed ninja.

"It is true. In addition to ninjutsu, Japanese ninjas are compulsory subjects, and they also have compulsory subjects for food, incense, medicine, qi and body, and are known as the Five Ninja Paths.

However, compared with the original ninjas, it is difficult for the ninjas to obtain the essence of ninjas and the five ninjas. After all, when the ninjas were established, it was the 15th to 16th centuries of Japan. In the past 100 years, the heroes were divided and the shogunate rule was in name only. It turned out that dozens of separatist forces appeared in the Iga region, where the central government was not strong, and they rebelled and attacked each other. Due to the limited land power of each force, they relied on the training of "special agents", that is, "ninjas", for reconnaissance, sneak attacks, assassination and other activities.

At that time, ninjas were not bound by too many bonds, so they were often able to devote themselves to their full enthusiasm when practicing, and their overall strength was very strong. However, now, even though the nature of ninjas has not changed, they lacked the previous focus in their cultivation.

After all, the flower world today is too tempting for them." Chu Yan has a very deep understanding of ninjas. Even if he cannot reach a thorough understanding, he can be regarded as a deep understanding. This sentence directly summarizes the reasons for the birth of ninjas and the process of developing to this day.

"You seem to be very familiar with ninjas, so do you know where the basic prototype of ninjas comes from?" There was nothing left to do, and Phoenix simply chatted with Chu Yan about ninjas while monitoring the dock.

Regarding the issue of Phoenix, Chu Yan showed a proud expression on his face, because according to reliable historical records, the basic theory of Japanese population came entirely from the Chinese Sun Tzu's Art of War.

Strictly speaking, the theoretical basis of ninjutsu was developed by Sun Tzu's art of war from China, and then it was developed with practice and ambushing skills in the mountains. During the Heian era, due to the rise of the samurai class, the art of war ambushing in the mountains was developed by samurai.

During the Yuanhei era, Yuan Yijing, who learned to ambush in the mountains, successfully used the technique of ambush in the mountains, and completed the theory of attack surface tactics. In the Southern and Northern Dynasties, Masato Kusungi developed military tactics of defense surfaces, and at the same time, ninjutsu and martial arts separated into different systems.

"The answer is unquestionable. The basic theory of ninjutsu is Sun Tzu's Art of War from China's magical book on military strategy, but they have extended it based on Sun Tzu's art of war. Unfortunately, it doesn't matter whether I admire it or not. What's important is that ninjas have now declined. At least, real masters are disdainful to get involved in worldly disputes.
