Then, before Ivana continued to ask, Lin En said with emotion, "It's been almost four years. I think you should have seen higher scenery in these years, right? Ivana?"
These words were undoubtedly a bit abrupt, and even confusing, but Ivana understood them, and looked at Lin En in disbelief.
Although several years have passed, Ivana still remembers every word someone said to her that night.
Outside of the harbor town is Nordland, outside of Nordland is the Sekas Empire, and outside of the empire is a much wider world...
In comparison, everything he was hysterically pursuing - the title of knight of a ruined noble in a village, could only be described as ridiculous.
But these words should only be known to her and Lotte.
“Brother…Brother?!” Ivana looked at Lin En in front of her, her eyes almost widened, and her voice trembled slightly.
The girl's eyes were like a scanner, carefully scanning every part of Lynn's body.
The hair color is right, the figure is right, except that she's a little taller, and the face isn't right either, but that might be because four whole years have passed.
But...how is this possible?
Ivana simply couldn't believe the guesses that emerged in her mind. After all, her brother was cowardly and mediocre, with almost no advantages to be found in him. Although Lot suddenly performed very well that night in Harbor Town, far beyond her own cognition, the gap between him and the famous magic star in front of him was like that between a dragon and a rat.
But now there seems to be no second possibility...
Facing the girl's excited and expectant expression, Lin En nodded first, then shook his head and said with a hint of cruelty, "I really want to respond to you, but unfortunately, I am not Lotte, nor am I your brother. I just happened to borrow his identity for a while."
"Borrow...?!" Ivana seemed to have difficulty understanding this word for a moment.
“For more details, you should read it yourself!” Lynn sighed, stretched out his hand and pressed it on the girl’s head, sending the relevant memories into Ivana’s mind.
This memory was relatively complete, starting from when he personally witnessed Lot falling from the city wall, to thinking about being hunted by the church, to using Lot's identity to sneak into the city, gathering intelligence and looking for the fleet heading to the land of wizards...
Given his current status and power, there is nothing to hide about these experiences.
A large amount of memories kept surging in the girl's mind like a slide show. The excitement on Ivana's face gradually turned into astonishment and panic, and her lips turned slightly pale.
She thought of countless possibilities, such as that Lot might have died that night in the harbor town, or that he had never traveled to the wizarding land but went to another place, or that he might have been avoiding her search all these years because he hated herself.
But she didn't expect that Lot had died long ago, much faster than she thought.
The cause of death was undoubtedly due to himself...
Ivana vaguely remembered that the night before Lot fell into the water, she had once again made several sarcastic remarks to him, and even hot-headedly rebuked him that if he could not pass this year's knight assessment, he might as well die. Lot did not respond as before, and then he did not come back all night.
At the beginning, she had maliciously thought that it would be best if her brother never came back, so that her father would look at her and see her efforts and dedication...
Now her 'expectations' and 'dreams' have undoubtedly become reality, and Lotte is really dead...
"I killed him..." Ivana was shocked and murmured to herself. The color on her face gradually faded and her body began to tremble slightly.
Lynn shook his head secretly. What "killed" Lot was not only Ivana's cold and sharp words, but also the intimidation of his father, Baron Pedro.
It has to be said that the Pedro family are all "talented".
An eldest son who is mediocre, cowardly and unable to bear his father's expectations; a second daughter who is stubborn, talented, resentful and eager for recognition. They also happen to have a father who is ambitious but incompetent and obsessed with reviving the family's glory.
The so-called children are nothing more than tools in Pedro's eyes. Ivana's appearance and talent in swordsmanship are bargaining chips to win over the Duke of Nordland. As for the only son Lot, of course he is the only candidate to revive the family's glory.
Even if one has less talent, one can still work hard, and even if that doesn't work, one can make up for it through other means. As long as one can get in touch with the Duke and convince the Bishop of the Church, there may be a chance for one to pass the knight election.
Baron Pedro's idea was indeed good, but he obviously did not consider whether Lot was willing and able to accept such an arrangement.
The miserable failures in the previous seven knight selections, coupled with the expectations and burdens of family revival, almost made Lot breathless. Ivana's sarcasm was the last straw that broke the camel's back. Lot, who already felt inferior because of his mediocrity and cowardice, came up with the idea that everything would be better after his death.
"Your brother may not be outstanding, nor a magic star, but he does care about you." Lin En said softly. "His death is not entirely your fault, and death is irreversible. If you want to do something to make up for your mistakes, you might as well do something more meaningful and live your life to the end."
"Although the parliament has cleared out the nobles, there are still many people like your father, Baron Pedro, in the empire. They are ignorant, stubborn, and have outdated ideas. Terrible incidents such as infanticide, lynching, and fighting still happen from time to time in the kingdom..."
"No one can stop what happened in the past, but at least we can reduce the chances of unpleasant things happening again."
Lin En said a few words of comfort, reached out and patted the girl's trembling shoulder, then took the black crow who was watching the show with him and walked out of the room alone, leaving Ivana alone for a while.
The moment the door was gently closed, a suppressed sob sounded synchronously.
“People only understand what’s most important after they lose something…” Lin En said with emotion.
At first, he just wanted to use Lot's identity as a temporary springboard to enter the harbor town and find the cripple Lawn. However, who would have thought that the old guy hid like a mole? Instead, he was caught by Pedro's butler and his men because his whereabouts were revealed, so he had to go back.
Fortunately, the situation in Pedro's family was very complicated, and it was not an exaggeration to describe the relationship between them as strangers and relatives. Lynn managed to fool around with the help of the description in Lotte's diary.
No matter what, the cause and effect has been completely resolved now. As for whether Ivana can figure it out, it is not something he can control.
Lin En's thoughts quickly broke away from these trivial matters. There were obviously more important things to deal with, such as arranging personnel to enter the space-time gate as soon as possible and figuring out the difference in the speed of time flow between the two worlds.
This is extremely important, and to some extent indicates how much time they have left to prepare.
Thinking of this, Lin En looked at the attendant who brought Ivana here before and asked, "Is Mr. Sean, who invented the pendulum clock, still in the capital?"
"Reporting to the Speaker, Mr. Sean should still be studying in the Alchemy Institute." The servant said respectfully.
“Then let him come to the reception room later.” Lynn guessed that Ivana, who was out of control, would cry for a while, so he changed the meeting place to the reception room.
"Please wait a moment. I will go and inform Mr. Sean." The servant withdrew very respectfully.
The wait did not last long. After learning that it was the famous Magic Star who summoned him, Sean immediately took his new achievements and rushed to the manor as quickly as possible.
"Mr. Speaker, are you looking for me?" After Sean walked into the room, he immediately bowed and greeted Lin En with a very humble attitude.
“Yes, there are some things that require your talents!” Lin En nodded and pointed to the seat beside him, indicating that the other party could sit down and chat slowly.
"It's my pleasure to serve you, Mr. Speaker!" Sean sat down on the chair a little stiffly. He knew that no matter his talent or strength, he would not be in the eyes of the magic star. The only special thing about him was that he invented the pendulum clock.
The other party had come to me specifically this time, most likely for the improvement of the pendulum and its subsequent popularization.
Sean is very self-aware and brought his achievements here in advance.
A special pendulum clock about 40 centimeters long.
"This is my new work that I improved after taking your suggestions into consideration. I added a minute hand and an hour hand, and also added the functions of telling time and adjusting the date..." Sean explained the functions of the new pendulum clock to Lin En incessantly, and the reserved look on his face was instantly swept away.
Lin En took the pendulum clock and took a few glances at it. He found that except for its somewhat simple appearance, it could almost be said to be a very perfect finished product.
"Your pendulum clock is well made. I think every city, town and even every person will use such a convenient timekeeping device in the future." Lin En did not hesitate to express his praise.
Sean was naturally delighted and soon immersed in the grand prospects created by this magic star.
However, Lin En suddenly changed the subject and said, "But I came to you this time because I hope you can continue to improve the timing device. Its accuracy is still lacking. It may be enough to deal with general situations, but if it is used in some magical experiments that require precise timing, it will hardly be of much use."
In particular, if you want to accurately evaluate the difference in the speed of time flow on both sides of the space-time gate, neither the pendulum clock nor the magic hourglass can do it.
Lynn's words pulled Sean out of his complacent state. He certainly knew that accuracy was a major weakness of the pendulum clock.
Since the timing principle of this thing relies on the isochronism of the pendulum's swing, it is already very good if it can stably achieve the time scale division in seconds.
"Mr. Speaker, give me three days, and I will find a way to improve the accuracy of the pendulum clock to one tenth of a second, no, one twentieth of a second!" Sean said gritting his teeth.
It was a rare opportunity for this famous magic star to ask him for a favor, so Sean naturally did not dare to neglect it and did not want to miss this rare opportunity.
"Not enough!" Lin En shook his head and said directly. "I hope the timer you develop can be accurate to one millionth of a second!"
One millionth of a second?!
Sean's face was full of shock and disbelief, and then he smiled bitterly.
"I'm afraid this...is simply impossible, Mr. Speaker."
If it was one fiftieth of a second, or one hundredth of a second, he could still try his best, but one millionth of a second, it could only be described as wishful thinking.
Even the legendary speakers may not react that quickly, right?
"Of course it is possible. Just use a more specific timing method than the pendulum, and you will find it is very simple!" Lynn said with a smile.
Chapter 524 Atomic Clock - Redefining the Passage of Time
What is the time?
To put it in scientific terms, it is a parameter that humans use to describe the process of material movement or the occurrence of events!
In order to understand the time represented by the day more accurately, various timers came into being. The basic principle is to calculate the average time consumed by a certain thing in the process of operation.
For example, the time it takes for a drop of water to fall, a handful of sand to flow, or a candle to burn out can be used to divide seconds, minutes, and hours. However, such a division is obviously not precise enough, because the time it takes for each drop of water to fall cannot be exactly equal, and there will inevitably be a significant error.
The pendulum clock invented by Sean is undoubtedly more advanced, because according to the law of simple pendulum, with the help of gravitational potential energy, the time spent on each swing of the pendulum is exactly the same, and its energy consumption is also very small. It only needs one spring to run for a long time.
So all we need to do is find something that has the same isochronism but is more precise, and we can create an efficient timer that is different from a pendulum clock.
Listening to Lin's story, Sean frowned. It sounds simple, but it is not so easy to find a suitable isochronous law.
“I can tell you two things that have isochronous laws. All you have to do is think about how to make them into timers.” Lynn said with a smile.
Sean paused and looked at Lin in surprise. He didn't expect that the Speaker had already found other isochronous laws, and two of them.
“First, it is a crystal of quartz, which is made of silicon dioxide. It has an interesting property, which is that when it is compressed by an external force, it will generate an electric current on its surface.
If positive and negative currents are introduced into the two sides of a quartz crystal, the crystal will deform and oscillate at a specific frequency..."
Lynn explained to Sean the operating principle of the quartz clock in a concise manner. To put it simply, the time is recorded by utilizing the property of the quartz crystal that it will oscillate continuously after an alternating current is applied to it.
Because the vibration frequency of quartz crystals is very stable, engineers normally cut the quartz crystals and control the current to make them into a tuning fork, which oscillates at a frequency of 32768 Hz per second.
If one vibration is taken as the benchmark, then a quartz clock made using this principle can divide time into thirty-two thousand seven hundred and sixty-eighths of a second.
Of course, the upper limit of the amplitude frequency of quartz crystals is far more than that. It is not impossible for the technology to reach hundreds of thousands or even millions per second.
After Lynn explained the principle of crystal vibration, Sean immediately became excited. As someone who had made a pendulum clock, he naturally realized the important role of this thing in timekeeping.
Especially in terms of accuracy, it is far superior to the pendulum clock.
It can be expected that one's invention may be eliminated before it is even implemented.
Sure enough, the insights and knowledge reserves of a legendary speaker are not comparable to those of a formal wizard like himself.
Sean's eager and excited expression quickly turned into a helpless look, and he said with a wry smile, "Since you already have an idea and a plan, why don't you just make this quartz clock?"
Lin En has found the most important isochronism law of the crystal oscillator. The only problem left is how to record every vibration of the crystal.
He didn't think this problem would be difficult for Lin En, the magic star.
Because of this answer, even I can think of it. Since quartz can carry electricity, then I just need to work on electromagnetic signals!
"I have always believed that professional matters need to be done by professionals." Lin En said with a smile.
If it were a few minutes ago, Sean would have happily accepted the praise from this magic star, but now he was a little amused, because Lin En had just explained the principle of the quartz clock very clearly, and his professionalism made him ashamed.
Then there is only one answer left, the Speaker cannot spare much time to tinker with these little gadgets, so he lets me do it.
