Fortunately, the maid sent by the demon king knew the language of the spiritual world. She communicated with Zou Yi in the language of the spiritual world, but there was no communication obstacle.


    Zou Yi became a military expert. She is also a little funny. He has never led troops to war. He is just an expert on paper.


    However, he knows a lot of military knowledge. How many men on earth don''t know military knowledge?


    So Zou Yi simply recalled the military knowledge she had seen when she was on the earth, organized the language, and then practiced.


    Although he is already an immortal, he is the most common big Luo Jinxian. He still has a lot of way to go before he becomes a chaotic real immortal.


    It is still a very important link to cultivate immortals and understand the way of heaven. The perception of the way of heaven can not reach the state that has been, it is difficult to make progress.


    While understanding the way of heaven, they also need a lot of time and energy to transform the mana in their bodies into fairy power.


    Now Zou Yi has not yet reached the time to understand the way of heaven in order to enter the chaotic realm of true immortality. What he has to do now is to slowly refine the mana in his body and make it become immortal power.


    It is said that there are immortal stones containing immortal power in the fairy world. The speed of cultivation will be faster by using the immortal power in the immortal stones.


    But now Zou Yi doesn''t have such cultivation resources. He can only rely on his own cultivation step by step to obtain immortal power.


    Zou Yi didn''t stop practicing until the night came. She went to explain the so-called military knowledge to the people in the demon world.


    He was still a little nervous in his heart. After all, he had never been a teacher. The students were all stronger than his demon world. It was strange that he was not nervous.


    The huge demon palace is full of people in the demon world waiting for Zou Yi.


    At the top of the throne sat the demon king. She was talking to several demon gods such as Zijun. She looked very happy.


    Zou Yi''s arrival attracted most attention. People looked at Zou Yi together as if they were watching a monster.


    The demon king got up to meet her and intimately asked Zou Yi to sit beside her.


    Now everyone thought of something. They stood up together and said in unison, "my subordinates have seen the demon king and master Zou Yi."


    Zou Yi blushed. How old are the elders of the demon world? They called him teacher. It really made him feel ashamed.


    The demon king was used to the worship scene and said calmly, "tonight is Zou Yi''s time to explain military knowledge to you. You don''t have to be formal. If you don''t understand or have any questions, just ask Zou Yi. "


    Zou Yi got up and hugged her fist. Lang Sheng said, "since you all know who I am, I won''t introduce myself anymore."


    After a pause, Zou Yi said with a smile, "I come from the earth. If I am far from the demon world, I have three interfaces. On earth, I am a very ordinary person. So if there is anything wrong with what I said today, please don''t be surprised. "


    Zou Yi speaks the language of the spirit world, because he knows that few people understand the earth language.


    The people who understand the earth language here, in addition to the devil, are about cangluan. Unfortunately, cangluan didn''t know where she had gone at this time. She wasn''t here.


    You can''t let the demon king translate for Zou Yi himself. It will only make the people in the demon world feel unhappy here.


    The maid who takes care of Zou Yi is Zou Yi''s interpreter. She listens to Zou Yi first. When Zou Yi finishes speaking, she will translate it into the language of the demon world and convey it to everyone.


    This is very troublesome, and sometimes words fail to express their meaning. But there is no other way but to make do with it.


    Fortunately, Zou Yi''s own military knowledge is not very profound, her words are easy to understand, and the maid translation is not very laborious.


    Zou Yi spoke for a while, and most people in the demon world understood it. As long as they are not magic soldiers, they all have their own wisdom. It is not difficult to understand some simple principles.


    Zou Yi saw that everyone had gained something, and she was also a little proud. When he was a teacher for the first time, the students were naturally happy to understand him.


    Time passed quickly, and unconsciously Zou Yi talked all night.


    After listening to the military knowledge all night, all the people in the demon world admire Zou Yi.


    They have never been exposed to such military knowledge. In addition to their long experience, they also deeply feel a potential crisis.


    Backwardness will be beaten. No matter where or when, this is an eternal truth.


    Zou Yi is outspoken about her origin. When talking about some theoretical knowledge, she occasionally takes the battle example of the demon world invading the earth as an example.


    Although this may cause the dissatisfaction of people in the demon world, it can more vividly explain the theoretical knowledge and make everyone more thorough in the spirit world.


    One night later, Zou Yi was tired and everyone was tired. So the devil asked everyone to have a rest and said it was going on at night.


    Everyone left one after another. When they left, they talked one after another. They were all talking about their own opinions, which was a great harvest.


    When the others were gone, the demon king smiled and said to Zou Yi, "well said, I also benefited a lot. In the evening, I''d better continue to tell you about the classic war cases. In that case, they will understand more deeply. "


    After a pause, the demon king smiled and said, "but don''t fight between us. It will make some people think of you."


    Zou Yi took a sip of water and said with a smile, "it doesn''t matter. Everyone knows I''m from earth. Naturally, I want to get that battle. Moreover, in that battle, we people on earth didn''t get any benefits. Even if we have opinions, it should be me. "


    The demon king smiled and walked up to Zou Yi: "didn''t you promise me to forget the previous things? Why do you remember so clearly. You don''t want to settle with me, do you? "


    Zou Yi looked at the smile on the devil''s face and obviously joked with him. She also said with a smile: "it''s not impossible to settle accounts with my sister. I just have to wait until my strength becomes similar to my sister."


    "You really want to fight me?" The devil couldn''t help laughing: "I''ll wait, but don''t let me wait too long. We still have a lot of business to do."


    Pause: "you are a one night teacher for many people now, but you can''t look like every master."


    Zou Yi laughed and felt more and more like a real good friend with the devil, and the relationship was getting closer and closer.


    If this continues, I''m afraid that when Zou Yi leaves the demon world, he will accidentally fall in love with this beautiful and dangerous big sister.


    Zou Yi doesn''t know that he used to obey the devil because he was afraid of the devil, but now he has quietly become willing to listen to the devil, just like a natural thing.
