The compulsory subjects for the two women include "Formation and Calculation", "Tianji Sect Formation and Tianji Finger", "Tianji Finger Basic Outline", "Tianji Finger Finger", "Tianji Finger Finger", "Tianji Finger Finger Finger", "Formation Analysis-Illusion Formation", "Micro-formation", "Gradar Formation", "Time and Formation", "Formation Control" and "Application of Array Flags and Formation Plates", many of which require hands-on practice.

After analysis, the four people unanimously agreed with Yan Jie's opinion that the courses learned by male and female monks are completely complementary to each other, complement each other, and are indispensable.

For example, Tianji Finger, this magic is the signature magic of Tianji Sect. It has been practiced since the first year. And according to Fairy Miaoyin, the cultivation level of Tianji Finger is also an important direction for investigation in the sect competition once a decade.

However, the exercises of Tianji pointer are divided into three parts, namely fingering, footwork and algorithm, among which algorithms are also called "mind method". Among these three parts, many predecessors believe that Tianji pointer takes mind method as the top, footwork is second, and fingering is actually the last.

However, in the courses arranged by Tianji Academy, male disciples were asked to learn the "algorithm" part of Tianji's fingers, and the contents of "step method" and "finger method" were handed over to female disciples for practice.

In this way, without enough communication, they will not be able to learn the authentic Tianji finger, and naturally they will not be able to understand the power of Tianji finger. This approach is just as Yan Jie said before. Tianji Academy is trying every means to let monks in the same room communicate with each other, and no one can hide their own personalities.

Similarly, there are the "formula array analysis-illusion array" practiced by female disciples and the "illusion array principle" practiced by male disciples. Just by listening to the name, you can know that "formula array analysis" must use the "illusion array principle", and it is difficult to master the principle of the illusion array only by learning the principles without example analysis. The Tianji Academy's adoption of such a course arrangement can be said to be very hard-working.

However, in this way, Yan Jie also discovered a problem from it.

"According to such subject arrangements, our time is almost full. Where can we still have time to take other subjects?"

"Yes!" Mingzhou also recovered and said, "This subject requires us to spend one day studying the content of two days, and it has both theory and practice. The more the course is, the more difficult it will inevitably be. If this continues, we will not have the energy to think about the elective courses..."

Xie Youlian nodded and frowned and said, "And every year, there are deadlines for elective courses provided by Tianji Academy. Once this year passes, these elective courses will not appear again. Everyone knows that the first year is the most important and needs to lay the foundation for the next nine years of study. If you don't choose the required courses at the beginning, it will be ten times more difficult to learn in the future..."

The three of them turned their eyes to Yun Shuyue at the same time.

Among the four, Yun Shuyue's family is most closely related to the sect because of the elixir. Because of this, Yun Shuyue often knows some inside information about the sect that is not worthy of being outsiders. The choice of subjects in the Tianji Academy may affect the future further study results of the four of them. Naturally, they must be very cautious. Even Yan Jie has to pay attention to Yun Shuyue's opinions.

Yun Shuyue thought for a while and said, "Do you all have the subjects you want to choose?"

Yan Jie, Mingzhou and Xie Youlian looked at each other and nodded at the same time.

"I understand..." Yun Shuyue nodded and said, "I just calculated that it does take a lot of time to complete these compulsory subjects. Even with the knowledge reserves of the four of us formations, it is difficult to say that there will be no problem when we are studying these subjects. Fortunately, Yan Jie proposed a better solution before, which can increase the learning efficiency of the four of us four times."

Yan Jie's eyes lit up and he said, "What do you mean is... the four of us studied different subjects separately, and communicated together after we came back?"

Yun Shuyue nodded and said, "Yes, that's what I mean. As the saying goes, one person has a shorter plan and two people have a long plan. According to the number of compulsory subjects now, each of us can only learn one or two elective subjects. No matter how many, not only will our energy not be guaranteed, but the course time is also difficult to adjust. Therefore, only by cooperating and further study can the four of us ensure the maximum benefits of the entire 27th Room!"

Mingzhou and Xie Youlian looked at each other, nodded, and said, "This method can be tried."

Yan Jie shook his head, poured a basin of cold water, and said, "You are thinking too simple. As the saying goes, you should think about defeat before you win. We four of us practice in a divided way. If the communication is smooth, we can certainly achieve the effect of fighting against four. But after all, we are selfish. How can we ensure that everyone will not be retained when communicating? I have always been straightforward, so I just talk in front of you. Although it may not be comfortable for everyone to hear it, it is better than regretting afterwards! In my opinion, if this problem is not solved, the four-person practice in a divided way will not work at all."

Yan Jie's words pointed out the key to the problem incisively. In their current situation, in the mathematics system of another world, there is a special term to describe: Prisoner's Dilemma.

Indeed, as monks, no one knows what the future will be like. The original partner in the same room may become enemies in the future. In this case, who will open up and teach others what they have learned with great difficulty without reservation?

But if everyone has a reservation to participate in communication, or even hides evil intentions, and deliberately adds some confusing content, it will not only greatly reduce the efficiency of learning, but may not have a counterproductive effect.

Mingzhou looked at Yan Jie and said, "Yan Jie, I think you are too worried... Even if the people who share are reserved, the acceptable people will always gain something, right? After all, it is much better than working hard to train yourself..."

Yun Shuyue and Xie Youlian on the side also echoed: "Yes, sharing and communication is better than isolating each other, right? Even if you keep some, it's understandable!"

Yan Jie couldn't help but sigh. Although he was helpless, he also understood that this was a custom that had existed in the world of cultivation for a long time. It was just a fool to change customs in a short period of time.

However, the current matter involves further study in the next ten years, and Yan Jie has to carefully explain it clearly. He is almost certain that if he communicates according to this method, the four of them will eventually gain nothing.

Yan Jie thought for a while and said, "Have you heard of Nash Equilibrium?"

"What kind of balance is included?" Mingzhou asked in confusion.

Yan Jie turned to look at Yun Shuyue and Xie Youlian. The two girls also looked confused and knew what Yan Jie was saying.

Yan Jie sighed and said, "I'll give you an example and you will understand."

He looked at Yun Shuyue and Mingzhou and said, "Mingzhou, Miss Xie, why don't we come and play a game?"

"Game?" Xie Youlian knew that Yan Jie had something to say, so he looked at each other with Mingzhou, nodded and said, "Okay, what game, you say!"

Yan Jie then took out three pieces of paper for painting talismans from the storage bag, handed them to Yun Shuyue and Xie Youlian's hands, and took out a large bag of spirit stones. Judging from the scale, it looked about two hundred yuan, and said, "I have a bag of spirit stones here, all of which are top-grade spirit stones, and there are quite a lot of them! However, only I know the number of spirit stones. You two might as well guess and write the numbers you guessed on the paper..."

Mingzhou took the talisman paper, smiled, and said, "Next to say, I know, I can guess it correctly. Whoever guesses will belong to this bag of spirit stones, right?"

Yan Jie shook his head and said, "That's too simple. It's not like a game played by us immortal cultivators. Besides, although I am not a monk, I also regard money as dirt. My rule is that you can choose a number between one or two hundred to write. I will give you a lot of spirit stones as much as you write. However, you are two people after all, and the numbers you write are likely to be large and small. I prefer modesty. Whoever writes fewer numbers can get two additional top-grade spirit stones. This is the rules of the game. Do you all understand?"

As he said that, Yan Jie took out two more top-grade spirit stones and swayed them in front of the three of them.

The two top-grade spirit stones have excellent texture and contain rich spiritual power. Whether used for cultivation or for formation, they are the best choice. In this way, the texture of the spirit stones in the bag must not be below these two.

If you can really win this game, you will make a fortune!

Needless to say, Mingzhou is not the case, but even if Xie Youlian comes from a family, he is still very moved at this time. One hundred top-grade spirit stones can be converted into millions of lower-grade spirit stones. The two of them now only have the cultivation level of Qi refining, and the scale of millions of spirits is definitely a huge sum of money even in the eyes of the two women.

The three of them never expected that Yan Jie, who seemed ordinary, could easily bring out such a considerable amount of wealth.

Yun Shuyue looked at Yan Jie and said, "Yan Jie, are you sure you want to play this game? This will cost you a lot!"

Yan Jie smiled and said, "We will spend some spiritual stones to meet each other. What's more, you may not be able to win all my wealth!"

Xie Youlian shook his head and smiled, and said, "Oh? Could it be that there is any mystery in your game?"

When she said the word "mystery", Yun Shuyue felt enlightened and her face suddenly became a little pale.

After Xie Youlian finished speaking, he was about to pick up the pen and write down the numbers on the paper, but suddenly realized the problem and fell into silence.

For a moment, the two women held the talisman paper in their hands, but refused to write for a long time. Their faces were hesitant, and their eyes were full of strangeness.

Mingzhou, who was confused by the sight, couldn't help but approach Yan Jie and asked whisper: "What are they hesitating about? You can get a lot of wealth by writing the numbers, but why do they hesitate? Could it be that you put some ecstasy curse on the talisman paper and control them?"

Yan Jie laughed silently and said, "How could I be so powerful that I can be so fascinated by these two people? Miss Xie is good at refining weapons, and Mingzhou's magic is even more strange and unpredictable. It is hard to defend against. How could I deceive you?"

"Then they are..."

Yan Jie smiled slightly, looked at Yun Shuyue, and said, "If you were one of them, what numbers would you write?"

"You want to test my eyesight?"

Yun Shuyue was in her heart and said, "Depending on the weight of your bag of spirit stones, it should be like two hundred. If I write down two hundred, wouldn't I earn 200 top-grade spirit stones in vain?"

Yan Jie said without comment, "Oh."

When Yun Shuyue saw Yan Jie like this, she knew that there might be loopholes in her thoughts.

She was very thoughtful and soon saw through the mystery and suddenly said, "I understand that if I write two hundred and the other person writes one hundred and ninety-nine, then according to your rules, the person who writes one hundred and ninety-nine will eventually get two hundred and one spirit stone. From this point of view, one hundred and ninety-nine is the best number!"

Yan Jie still smiled and said, "Miss Yun, if you continue to think about it, you should understand why the two of them are so hesitant."

"Push another step..." Yun Shuyue thought for a while, suddenly understood and exclaimed: "Yan Jie, you..."

Yan Jie waved his hand and said, "Let's see what kind of numbers they will write!"

He coughed lightly, woke Xie Youlian and Mingzhou up, and then said, "This is just a game, why should you take it too seriously... Mingzhou, Miss Xie, you should already know it in your heart, right? Why not start writing now, how about it?"

Xie Youlian and Mingzhou looked at each other and wrote down numbers on the talisman paper.

Yan Jie took back the talisman paper from the two. Yun Shuyue looked closer and was surprised to find that the numbers they wrote were exactly the same.

"You guys really wrote one!" Yun Shuyue's face changed. Although she knew that the result of the calculation was indeed the case, looking at the big bag of spirit stones and looking at the two talisman papers with "one" written on it, Yun Shuyue only felt that the facts that happened in front of her were too absurd and incredible.

Yan Jie seemed to have expected it, so he took out two top-grade spirit stones from the bag and handed them to the hands of the two, saying, "The game is over, I wonder what you think!"

Xie Youlian glared at Yan Jie and said, "You Taoist priest are not a good person!"

Yan Jie was stunned when he heard this and said embarrassedly: "It's just a game. Miss Xie doesn't need to be so worried..."

Xie Youlian still looked angry and said, "You made everything in advance, right?"

Yan Jie sighed and said, "Not bad."

"Hmph, I thought you were so generous, but I didn't expect that I was hit by your plan and was teased by you for nothing! Humph!" Xie Youlian turned his head angrily, as if he had suffered a huge grievance.

Mingzhou's face was not very good at this time. He silently took the spirit stone handed over by Yan Jie, looking thoughtful.

Yun Shuyue, who was standing beside him, understood the feelings of the two, sighed, comforted Xie Youlian and said, "Youlian, don't be angry anymore. Yan Jie Zuiweng's intention is not about wine, he has other words!"

"What else is there?" Xie Youlian turned around and looked at Yan Jie. When she saw the smile on Yan Jie's face, she felt indescribable and wanted to catch this treacherous Taoist priest and beat him up.

Yun Shuyue smiled and said to Yan Jie: "I will tell you what I will say next!"
