"Flange, you have already understood the law of conservation of energy that you mentioned yesterday, but I can't think of. How to create an absolutely isolated system? Does it exist only in assumptions?"

Flan flipped through the textbooks that were few of the pages left. The little prince's learning ability was definitely beyond the scope of normal people. He could be said to be a genius. He was a teacher who was really happy. Even if the other party often asked some wonderful questions, he found it very interesting.

"Your Highness, an absolutely isolated system does not exist. The meaning of the law of conservation of energy lies in explaining the form of existence of the concept of energy." Flange closed the book and stretched out his right hand to the prince, indicating that the other party put his hand on it, "Did you feel it? The heat in my hand is transferred to your hand. Everything in the world is moving, from one side to another, from one form to another... And we don't know yet whether there are other universes outside this entire universe? So this entire universe is not an absolutely isolated system."

"Gu Zhi." The little prince nodded calmly and said, "There are still countless unknown things in this world. Gu already understands what you said to change this world."

The time has come. Flan took back his right hand and piled up the teaching materials he brought. Just as he got up, he suddenly remembered something and said, "Your Highness, I have been taking a leave tomorrow and I want to go back to the imperial capital. Has General Manager Wei told you? You have learned almost all your elementary mathematics. I have prepared a test paper for you and treat it as tomorrow's homework. The time is two hours. After you finish it, you can just put General Manager Wei in my room."

The little prince was silent for a moment and suddenly asked, "What's wrong with you when you return to the imperial capital?"

Flan was stunned and replied: "It's a private matter... My friend came to the imperial capital from Yunzhou. We haven't seen each other for nearly five years. We are very concerned about each other..."

The little prince never asked Flan about him, and his communication was limited to his studies. I don’t know what happened today, Flan observed the other person’s expression and added another sentence by reason of deception: “He is a man.”

The little prince smiled. Although it was only a moment, Flan was sure that he had seen it. This was the first time... He blinked unconsciously.

"The teacher who taught Gu to read and read before, you smiled very much like her." The little prince used 'her' rather than 'him'. Flan listened silently, and had a bad premonition in his heart. Sure enough, he heard the other party say: "She is talking about Gu's affairs outside, and has been dealt with... Don't be like her."

There is a small detail here. When the little prince was talking, he looked down at his legs. Flan immediately realized that he could not tell what he felt. As the prince, he was trapped in this remote palace, so he naturally had a reason to do so, and this reason was also very obvious - it was because of the other party's legs.

The prince is a disabled person. He will lose his head when he says this. Even to his teacher, Flan did not reveal any slightest expression. With today's medical level, only one limb replacement surgery can solve the problem. However, the prince is still too young and his body has not yet grown up. Limb replacement surgery must be done until his body is fixed. In other words, he must live in this other palace until he grows up. He must never show up in front of others until then.

Flan opened his mouth and hesitated a little when he spoke to his lips. The little prince had no malicious intentions in saying these words, and was reminding him that although it was not so comfortable, Flan hesitated whether he should say a few words of comfort.

To be honest, like the little prince, he is not very good at dealing with people.

"I... I won't talk nonsense, please rest assured." Flan looked at the little prince's eyes and said seriously, "You are the smartest student I have ever taught. As a superior, the most important thing is your brain, not other things... Believe me, in terms of mind, you are no worse than anyone else."

"Flan." The little prince finally laughed, and he smiled, "You really can't be good at speaking."

Flan always felt that the little prince was born different from the emperor and the late queen. At the wedding ceremony of the queen that year, he secretly watched in the corner of the Temple of Light and saw the Queen holding the emperor's hand and walking on the red carpet. The diamonds inlaid on her black hair were as bright as the stars in the sky. Even so, it could not cover her breathtaking appearance. When she smiled, the lights in the Temple of Light seemed to dim, and all the light gathered on her.

At this moment, looking at the little prince's smile, he was actually a little distracted.

The memories that had been somewhat vague many years ago became extremely clear at this moment - the most beautiful thing about the Queen was not her appearance, but her unique and dazzling temperament, like wildfire, cold and ostentatious, but after the fire was gone, the desolation and coldness of the endless grass was hard to describe in words, and it was unforgettable for her to see it for a lifetime.

"Is there anything on my lonely face?"

The little prince touched his face in confusion. Flan was suddenly awakened by the words, shook his head in a daze, and replied, "No."

The little prince looked at him, and his eyes clearly wrote - Then why are you stunned when you look at me? Flan finally woke up and smiled bitterly, saying, "I just remembered some past events... Your Highness doesn't need to care."

His Royal Highness is not like the emperor, nor has he inherited the appearance of the Empress. Perhaps because of his childhood sweetheart, he is also very restrained in character. However, the mother and son are mother and son after all. In him, Flan did see the shadow of the Empress. Then Flan had an inexplicable idea: No wonder His Majesty the Emperor would rather spend a lot of effort to cover up the truth and live in seclusion than to change the Empress... The Empress was born in a noble family, but the Prince's mother tribe had no real power in both military and political circles, so he could not help him. He himself was disabled. If it were not for the emperor's favor, the position of the Prince would have been replaced long ago.

The other palace is deserted and quiet, and it is suitable to calm down and do research. In addition to the flange class, I used this period to sort out the experience I had accumulated before and reorganized a way of thinking... Before I knew it, it had been more than a year.

"In a few more days it will be my lonely birthday."

After the class on the day, the little prince suddenly said to Flan. After more than a year of getting along, the two of them have had a lot of feelings for each other. In addition to their studies, the little prince also said a lot more to Flan. Looking at his dark eyes, Flan patted his forehead and pointed at each other.

"I understand." He smiled at the little prince, "Your Highness is asking me for gifts."

The little prince coughed uncomfortably and said without gaze: "Last year, you celebrated your birthday, I gave you a set of the latest astrology...

Flan was amused and crying: "My Your Highness, the debt of favor is not calculated like this... OK, don't worry, in fact, I have prepared a gift for you long ago, ensuring that it is unique and you will never be able to buy it with money."

The little prince looked at him suspiciously, with a faint expectation in his eyes, and nodded to signal that he could leave.

A few days later, His Royal Highness the Crown Prince's eighth birthday.

The chief manager Waynedu received a report that he personally took a car to the small courtyard where Flan lived early in the morning. He saw that the latter was struggling to drag a pile of things into the rear box of the passing car, including wood and metal parts, and each of them could be used as a weapon in terms of size. He walked over in confusion and helped him carry a metal part into the rear box, asking: "What is this for?"

"Secret." Flan had a mysterious expression, "Just wait and see."

Wayne blinked. He had been the chief manager for so many years. Except for the master, no one dared to talk to him like this. Over the past year, the more he looked at Farlan, the more interesting he felt. Whether he was inferior to his identity or someone higher than him, he had an equal attitude towards his attitude, even if he was no exception to His Highness the Prince, it did not make people feel uncomfortable... It was indeed very interesting.

The chassis of the passer was pressed by these things and Wayne Du simply asked the flange to sit in his car and relieve the burden on the passer. He came to the teaching study and saw the little prince's wheelchair parked at the door, staring at the passing passer, and sweeping around the pile of things behind the car that could not even fit the cover, then looked at the flange that was walking out of the car with Wayne Du.

Flan was wearing a sea-blue work clothes today, and a half-shrunk baseball cap was on his head. He moved out the things in the back box of the car, straightened up and supported his waist to breathe, then rolled up his sleeves and started working. Waynedu looked at his two white and thin arms, and secretly lowered his vigilance in his heart. The little prince slowly moved behind Flan in a wheelchair and looked at the other person's every move curiously.

"Your Highness, do you still remember the law of conservation of energy that I told you?" Flan said to the little prince without looking back while assembling the parts on the ground.

"I remember." The little prince replied, "in a closed system, the total energy remains unchanged."

"So have you heard of perpetual motion machines?"

The little prince widened his eyes in disbelief.

"You... do you want to build a perpetual motion machine?"

"Of course not, my highness." Flan squatted on the ground, turned his head and looked at the little prince, "Don't forget the law of conservation of energy, perpetual motion machine you just recited? Do you really believe that this kind of thing exists?"

The little prince felt that he was mocked and said unhappily: "You raised it first."

"So you believed it." Flan said.

This is the first time since the little prince was born that he was so straightforwardly mocked in person. Wayne Du, who was beside him, also changed his face. Just as he was about to scold him, he saw the little prince raise his hand to block him and said thoughtfully: "What do you mean is that you should believe you?"

"You are changing your concepts and deliberately distorting my meaning." Flange fiddled with parts on the ground and laughed at him, "It's not ridiculous to have delusions. Is perpetual motion a delusion? Of course, why? Because it violates the known truth... Humans initially thought that the sky was round, but later they discovered that there was a ball standing under their feet. Then they thought that the sun and stars in the sky were all revolving around them, but the facts proved that they were wrong again... The so-called truth is something that is constantly established, questioned, overturned and re-established."

"Delusion is the driving force for progress. Because of delusion, we can fly into the sky and enter the universe... Your Highness, you can clearly understand what delusion is, and understand what obstacles and difficulties are impossible to achieve. Even so, you still want to work hard to realize it... Then this is not called delusion, but ideal."
