The story of One Piece has been updated to the chapter of the Kingdom of Peace. In this chapter, there is a very important message about the alliance oath between the Guangyue clan and the Fur clan in the Kingdom of Peace: whenever one party is attacked, the other party must go all out to help!

It's precisely for this reason that Boss Cat Agkistrodon and Duke Dog Lan decided to go to the country of peace and see this legendary country!

However, after going through all kinds of hardships at sea, the scene of their arrival in the country of peace was different. Instead of being treated as a monster, they were almost cooked into delicious dishes and became full food for the warriors of the country of peace!

With such a huge contrast, people can't help wondering, what happened with China that made the warriors break the covenant?

What is the current situation of the fur clan in the country of Harmony?

it's been too long, and the warriors of the country have long forgotten their promises!

It's easy to understand why this happened. After all, hundreds of years have passed since the agreement between the country of peace and the fur clan! The life span of the fur clan is much higher than that of the samurai in the country of Harmony. Therefore, it is natural to make an agreement among the fur clan, which can be passed down from generation to generation!

On the other hand, due to the large number of people who have experienced it, this agreement has become a legend for the country of Harmony, and only a few people have inherited it, while most people have forgotten or even don't know about this agreement. In addition, because the country of Harmony is closed to the outside world, it is reasonable to regard fur people as monsters!

Not everyone has forgotten their vows, but the Guangyue clan firmly remembers them.

It is not difficult to see from the conversation between Mitsuyuki Yutian and the boss of the Cat Agkistrodon and the Duke of Canlan that with the passage of time, even the Mitsuyuki people have forgotten the previous agreement, but as the generals of the country of peace, they still remember the agreement very clearly, that is to say, only a few people in the country of peace know it now!

the root cause of this situation is the long-term closed door policy!

From the present situation, it is not difficult to find that there are only two situations for the Fur clan and the samurai in the land of peace

1. Most people don't know the agreed things, and even the Fur clan leaders don't know what they look like, but only regard them as monsters!

2. The high-level inheritance of the country of harmony is close to the fault, and only a few people maintain a good inheritance!

From this point of view, the forgotten oath is mainly caused by the long time, but in the final analysis, it is mainly caused by the closed-door policy of the country!

It is precisely because of the consequences of the closed door that the tragedy of the cat, the viper and the Duke of Canlan occurred, which is also the fundamental reason why Mitsuyuki Yutian had to change the status quo of the country of peace after going to sea until his death! This is not only a solution to maintain the oath between the country of peace and the fur clan, but also a better way to save the country of peace!
