We are in front of Wan Shi Tong's library. It looked the same from the outside as in the series. We managed to get inside the library the same way as team avatar did. Only private 2 was left behind since he is afraid of heights.

(I will remind everyone which are the rules. No fighting, firebending, stealing, shouting, or damaging books in any way possible. Please avoid all war tactic knowledge as well as possible. Avoid making the spirit angry. Finally, be ready to give away knowledge to him. It is up to you how you will use this knowledge. The goal is to improve not destruction. He is not going to ban anyone here if you follow these rules. At least I hope so.) Shamo

(You are free to search on your own. Remember to share it after we leave. Not everyone is coming with us. It would not be fair to him to lose this change.) Zhao

I was happy that they were going to follow my lead. I do not know if they will follow it. I hope they do.

As we stepped into the hallway we heard loud wing noise. Everyone started to hide. I choose to stay on foot. Ten meters long owl was approaching me.

He is for sure the strongest being I have seen yet. Those sand sharks were nothing to him. How could Sokka have managed to hit him? He should have heard him coming. Was he so overconfident to not count him? I am afraid.

(I have not seen a human in many years. The most had given up coming since this place was guarded by my pets. Normally I would not allow you to come here but you all have proved to be deserving to come here. You all will still have to give knowledge to my library. I am Wan Shi Tong he how knows ten thousand things. Welcome to the greatest library ever existed, human.) Wan Shi Tong

I opened my back to reveal my notes to him. They were full of possible future knowledge and warning what Zhao and others after him are going after. Wan Shi Tong knew right away what my notes contained within. I had advised him to hide knowledge about ocean and moon spirit. Or test him if he is worthy of its knowledge. It looks like he approved my plan.

(I am planning to give these too to your great library.) I had given him books from earthbending academic which was from my uncle and the latest releases from Gaoling city.

(I am happy to receive your generous other. I have some questions for you later. I will bring these Gaoling works to their proper place.) Wan Shi Tong

I signaled others to come closer. Everyone gave books from their family´s libraries. This was happily received by the spirit. Zhao came at last.

(How can I know that knowledge here is equal worth to my book?) Zhao was carrying scrolls from his late master.

(No knowledge is equal to the other. A reader gives worth to the knowledge and books. You can be sure that the knowledge here will surpass your expectations. I trust you will not destroy anything in here. I hope you will find what you are looking for.) Wan Shi Tong

Wan Shi Tong left us to bring these books to their proper place in here and prepare anything necessary.

I do not have any plans for what I am looking for. I think I will go to the planetarium. I am interested if fire nation's darkest day has already happened. I think it has but I should make sure.

I saw one knowledge seeker. He seems to be trying to get me following him. I soon came to the planetarium. It seems like I was meant to be here.

This novel is published on a different platform. Support the original author by finding the official source.

(Good. You have arrived.) Wan Shi Tong

I was surprised by him since I was not expecting him yet.

(I have a book that might interest you.) He showed me the book without anything on the cover.

I took the book and started to read what was inside it.

I saw the table of contents full of different names. I did not explain anything to him. I choose a random name and started to read from it.

”I came to the great library to find answers to how I ended up into this world. I had read a book about a world like this before which showed me a possible future. To my surprise, these things did happen. Such as general Old Iron did fight against avatar Yangchen. Things ended up well but could I have done something better. No doubt that every generation will remember what did happen here.”

I needed to process what I had just read.

I am not the only one to have experienced this. There have been others and that person seems to have different knowledge than I do. He or she must have known things from his/her time. I must read are last person's final words.

”To you how are skipping to the end. Shame on you. Do not read spoilers. That is bad for you.”

This made me angry. You had done that on purpose. Those letters were way bigger than anything before or after.

”Just kidding. There have been many people lost to the wrong world for a long time. Mother of faces can not notice everybody but everyone from here is connected to this world. In return for her mistake, she will not take your memories away except for a few. Everyone has connected to this world in different ways. In my case, I saw the movie about this world about the beginning of the war against air and fire nation. It was an amazing movie. I hope that nothing like that happened during your history. Good luck finding your happiness.”

After reading those words, I started to read the book without noticing how much time I was taking. Not like anyone here was doing anything else either. Everyone was reading the book without noticing how hungry or thirsty we were. We never knew Wan Shi Tong could keep our health with his methods but it did not help against necessary nutrients.

Our friend outside was not doing well. He was eating the sand shark alone and scared.

Wan Shi Tong is not a spirit who would warn others about this. This makes him happy actually. He loves to see people reading without a care of the world. He is like that too. Shame that he can not forget things he has known.

Oki is studying flora. What is safe to eat and whatnot. He is trying to find a plant that can be cultivated back home. He did not notice that he gained massive knowledge about poisons and antidotes. He could become the world's greatest poison master if he chooses to use it. These books were lost since long time ago.

Wan Shi Tong saw danger which was present but he excluded it. No knowledge is good or bad. The only thing that matters is how it is used. He knew that Oki did not have murderous intent rather a kind one.

Private 1 was looking for anything which was about the walls of Ba Sing Se. Spirit thought that he had dark ideas but he was surprised. He was also looking book about architecture. He was looking away to build a dam and a big one at that. Wan Shi Tong let him continue reading without the problem.

Lieutenant Zhao was waiting for him.

(Where can I find knowledge about spirits of ocean and moon?)

He had looked at everything about water clans, both south, and north. He is trying to find everything which is to know about his enemy. Their culture, legends, manners, teachings, power structure, and finally spirits. He planned to place spirits in the last place since he was the most interested in them. Hardly anything of them was written to the books which he read. This made him even more interested.

Wan Shi Tong saw his eagerness which was not a bad thing so he planned to test him.

(I am not interested why you are looking for knowledge about the spirits but do not use it to war. I will not allow you to do so. I will give you only one chance to prove yourself worthy. Tell me why I should trust your knowledge which might harm my cousins.) Wan Shi Tong

(I have come from a faraway land. I was the strongest warrior in my village. I was trained by the best firebending teacher. I rose in ranks faster than anybody. I am part of the greatest army ever existed but I will… No. This is not enough. I can do much more to the world than this. Nobody has noticed that my firebending is getting weaker and I do not know why. No knowledge from fire nation could give me an answer. I am hoping to look for anything that can help me to be the best that I can be. I am trying to look for knowledge of other cultures. Air nomads were proven weak so I am looking at everything which is to know about water tribes. I need knowledge of their spirit. To be honest. I do not know if I am worthy but this is my only choice.)
