Hope Your Words Come True

As they reached the crossroads, Wayne waved goodbye.

Although he was also curious about how a light bulb could do a backflip, he had to leave because his family was having Clockmakers' Guild dinner that night.

Li Mo took the girls home.

Even at home, the father dressed respectably, clearly to maintain the demeanor of a sixth-rank lord.

Upon seeing his son return home with three pretty young girls, the father immediately gave him an approving look.

--As expected of my son!

Then, composed himself and formally went up to greet them.

Helen and Anna were quite familiar with each other, but Estelle was not very familiar; they had only met once.

Li Mo then introduced, "Father, Estelle only transferred to our class not long ago. Please don't joke around; Estelle is very capable."

There is no better son than a father.

Li En understood immediately and nodded in agreement.

Anna put on an apron, poured everyone some black tea, and then went to the kitchen to prepare dinner.

As the father picked up his teacup,

He deliberately turned his wrist outwards.

This way, the silver cufflinks of the Municipal Chamber of Commerce's special advisor can be subtly revealed on the cuffs.

Seeing that Estelle was simply quietly drinking from her teacup and hadn't noticed the cufflinks, Li En had no choice but to take the initiative to start a conversation:

"Speaking of which, Miss Estelle, you haven't been in Mondel Town for long, have you? Things have been tense in town these past few days, so you'd better be careful when you're out and about. This morning when I went to the town hall for a special advisor meeting, I heard from the police station that the number of patrol shifts on the streets has doubled."

Helen whispered, "Uncle Li En... did he go to City Hall today too? I heard that Mr. Turner and Mr. Crawford were taken away this morning."

"Indeed, sigh... Actually, I was originally just an honest businessman who didn't like getting involved in town affairs, but Lady Caroline insisted on bestowing upon me a [Sixth-Class Lord] title. Since I've received a royal title, I should at least share some of the town's responsibilities..."

Li Mo sighed.

He's here! He's here... Dad's signature move is coming our way!

It's been several minutes since we've heard a story from Lord Sixth Class!

"Don't underestimate the title of a sixth-class lord. Our Mondel Town is, after all, a remote little town... In all the years since the town was established, apart from the hereditary title left by the old governor, I'm the only one who has been granted a sixth-class lordship through industry. According to the kingdom's etiquette, a sixth-class lord not only receives a fixed royal allowance every year, but also doesn't need to bow to the local sheriff and tax officials, and also..."

Li En gave a thorough explanation of all the benefits of a sixth-class lord.

He concluded by humbly waving his hand, "Of course, it's just empty fame, nothing more. I don't usually mention it at home."

Upon hearing this, Li Mo remained noncommittal.

My dad's been reading "The Kingdom Nobility Etiquette Handbook" every day now... If he really wants to show off, let him fly.

Actually, it was mainly for Estelle's benefit.

Estelle didn't react much, only nodding slightly and saying, "Impressive."

Li En didn't mind, and said to himself with emotion, "On the other hand, we owe everything we have today to Her Majesty the Queen."

Estelle looked up at Li En.

Li En said, "You students in academy might not understand this as deeply. What was it like working in industry before? You'd painstakingly improve a part in a workshop, and within three days, the factory across the street would bribe a craftsman to copy the blueprints. If you went to the city hall to sue, Turner and his gang, having taken bribes from the Oliver family, could drag the case out for three to five years!"

Helen nodded in agreement. "My dad used to sigh about things like that all the time."

"But things are different now. Since Her Majesty the Queen assumed power and implemented the new patent protection law, anyone who dares to copy a Class A patent will be dealt with according to military law! Not only have we been exempted from heavy taxes for three years, but subsidies have also been allocated to the factory in a real way. Take this morning for example, the Special Envoy's Office acted swiftly and decisively, and in half a day they had pulled out all those parasites like Turner and Crawford!"

Li Mo chimed in from the side, "There used to be people gossiping behind her back, saying that Her Majesty the Empress is only sixteen years old this year."

"So what if she's young? What do those people outside know! The war in the North is intense, and there's collusion between local officials and merchants within the country. If it were one of those indecisive old kings, they would have been busy raising taxes and conscripting men long ago. But our Empress is simultaneously strengthening the military and boldly reforming the laws and supporting industries. In my opinion, Her Majesty's vision and decisiveness surpass those of any monarch in the past hundred years!"

Estelle sat quietly on the sofa.

He then lowered his eyes and took a sip of black tea.

Why bring this up? It won't make me happy.

A faint smile played at the corners of her lips, and then she said:

"Mr. Li En is very farsighted. With your vision and Li Mo's talent, you will certainly be more than just a sixth-class lord in the future."

Above the sixth rank of lord, there are fifth rank lords and even true barons.

Upon hearing this, Li En waved his hand and said, "Haha, a fifth-class lord isn't so easy to be granted, but I'll take your good wishes anyway! You two sit and chat first, I'll go to the wine cellar to pick out a good bottle of fruit wine, and then see if Anna needs any help!"

After my father passed away.

Li Mo tidied up the table and prepared to start explaining the math problems.

"Come on, before dinner is ready, let's tackle all the problems you've been accumulating."

Helen immediately opened her notebook and asked a question.

Li Mo glanced at it and replied, "The key lies in the limit and the instantaneous rate of change. You see, suppose the function corresponding to this curve is y equal to the square of negative x plus 4x. We need to find its highest point, which is the maximum value of y."

Helen said, "If we use the completing the square method that Mr. Harrison taught us, we can also calculate that when x equals 2, y can be at most 4."

"Yes, quadratic functions can be solved using the completing the square method, but for more complex ones, we can use a different approach. As I mentioned in the first salon, when the increment of the independent variable approaches 0 infinitely, the limit value obtained by dividing the increment of the dependent variable by the increment of the independent variable is the derivative at that point. For functions like y = x to the power of n, the rule after differentiation is n multiplied by x to the power of n minus 1."

Estelle said seriously, "So for y equal to the square of negative x plus 4x, its derivative is negative 2x plus 4?"

"That's right. Since the slope is greater than 0 on the left and less than 0 on the right at the highest point, and the function is continuous, then at that instant of the highest point, its tangent line must be horizontal, meaning the derivative equals 0. By adding 4 to -2x, we can directly solve for x to be 2."

Helen's eyes lit up. "So that's how it is! That makes much clearer!"

"You'll encounter similar problems frequently in the future. Here, try to solve these two problems using this method."

"Good!"

Helen and Estelle began doing the problems.

After observing for a moment, Li Mo quietly murmured a word of silence to himself.

--Activate a state of focus.

This is a good opportunity to observe Estelle closely.
