This fowl asked about the way to defend in many situations, and listened to Mozi's detailed explanation, which was really like a full opening of the seven tricks, and many of the previous incomprehensions were clear at once.

He said respectfully, "Master, if you say that, is it true that as long as you master the above methods, you will be foolproof?" ”

"There is no foolproof defense in the world, even if it is impregnable and impregnable, there will always be weaknesses. There are five situations in which it is inconvenient to defend: the city is too large and the number of defenders is small, which is the first inconvenient situation to defend, and the manpower is insufficient, even if there is no way; The city is too small and there are too many soldiers and civilians in the city, and there are many people but little food, which is the second inconvenient situation to defend, and when hunger occurs, all things can happen; The bazaar is too far away from the city, which is the third inconvenient situation to defend, and the transportation of materials is inconvenient, which affects the speed of supply; The reserve of fortified materials is outside the city, and the rich people are not in the city, which is the fourth inconvenient situation for defense, which will cause the rich people to not resist wholeheartedly, and even flee when the war starts, and the fortification materials are prepared for the enemy outside the city; The lord or monarch is cowardly, incompetent, and incompetent, which is the fifth inconvenient situation for defense, and this kind of general cannot be issued, and the traitors are in charge, and it is difficult to defend the city. Roughly speaking, there are 10,000 residents in the city, and the city is within a radius of three miles, and this situation can basically be maintained. However, the world is impermanent, and the changes in the situation on the battlefield are complex, so it is necessary to analyze them comprehensively and not to be dogmatic. Since this kind of war is initiated by man, the main aspect of decision is still man. Except for a few Heavenly Dao, even if the Heavenly Dao intervenes, it is also a good person to borrow it for the Heavenly Dao. Mozi said.

"Disciple understood!" Fowl nodded in thanks, "There's something else that's a bit confusing. We Momen advocate both love, but when Master talked about defending the city just now, he talked about many strict law enforcement methods, especially the prohibition of defending the city, which is mostly based on killing, isn't this contrary to love? ”

"What's the contradiction? If it weren't for such a strict order, wouldn't the number of dead and wounded be even greater, wouldn't it be great love to severely punish a few who violated the order in exchange for more lives? All kinds of brutal killings on the besieging side are also to prevent the siege and protect the soldiers and civilians in the city, isn't this also great love? The love I advocate is not pedantic love, but love that understands righteousness and makes trade-offs. Mozi looked at the East China Sea and said slowly.

"The disciple has been taught! Thank you, Master, for your teachings! "I am very happy to know the truth.

"In the world, it is difficult to distinguish right from wrong, only love, there will be no wrong. Treat others with a compassionate heart, but the compassionate person must also have the means to subdue the dragon and the tiger, rather than blindly being cowardly. We learn the way of martial arts, the way of offense and defense, and the way of governing the country, so for this reason, when compassion and benevolence are not compatible, we will use thunderous means to surrender them. Mozi motioned for the bird to be ready, and cut a piece of jerky for him, "Among the many disciples, you are the only one who is my true disciple, and I hope that you can quickly take charge of the Momen and take on the responsibility of the Momen." In the future, Momen will be divided into two gates, the inner door will teach the disciples, pass on the merits and teach the law, take into account the allocation of resources, and collect information from all over the world for analysis and practical matters. The outer gate is the person who releases the door and serves as a political dignitary of various countries. As the chief disciple, you have to take care of both the inside and outside, and do the duty of a good person. ”

These words flattered Yu Huali, "With the master here, how can the disciple He De dare to take on such a heavy responsibility." ”

Mozi waved his hand and stopped his words, "Don't worry, this matter will have to wait for at least a few years." The reason why I have this plan is that I am very optimistic about your martial arts attainments, and on the other hand, you are calm and not arrogant or impatient in knowledge. And I know well that observation and righteousness are clear, and I have observed these points for a long time, and I also believe in my vision. As you have heard, many of the ways I have just spoken about defending a city involve the construction of equipment and cities, and there are very few people who have this ability, so I have plans to study this, and once I delve into it, it will be difficult to distract from it. ”

Only then did Yu Huali understand Mozi's intentions, "Master, I heard that there is a strange person whose name is like Gong Yi, who is highly accomplished in equipment, why not invite him to join my Momen to teach the Tao, wouldn't it save a lot of trouble?" ”

"Haha, the idea is good, but such people are arrogant, how can they easily live under people, and even then they are under kings. Besides, in terms of equipment, I dare not say that I am unique in the world, but no one dares to call myself the first. At this moment, Mozi leaked domineeringly.

The fowl suddenly opened his mouth wide, "The disciple never knew that the master was so proficient in equipment, but the disciple's words were reckless, don't blame the master!" ”

"I can't blame you, I have three skills, one is martial arts cultivation, there are many talented people in the world in this regard, and I have the name of self-knowledge for my teacher. The first is the way of governing the country and the way of offense and defense, and the teacher has a little self-confidence in this aspect. The first is instrument making, which is passed on to my own school, and I have studied it in many ways, and I boast that I will not lose to the world. ”

The longer she spent with Master, the more she felt that Master was like the sea, vast and unfathomable.
