However, there's a method to making money.
Because in his previous life, Ye Yu was quite fond of reading novels, including historical farming stories.
As a result, Ye Yu knew how to make things like glass, soap, snowflake salt, snowflake sugar, black gunpowder, and more.
But these things, he definitely couldn't bring out now.
The potential benefits were too great, and he wouldn't be able to protect them!
If he were to take them out, he might lose everything, including his own life!
After careful thought, Ye Yu eventually settled on a safer method of making money.
He decided to open a tutoring class in NuodingCity, offering lessons in mathematics and drawing.
After attending Nuoding Academy, Ye Yu realized that the mathematics level on Douluo Continent was abysmally low.
They only taught the most basic addition, subtraction, multiplication, and division.
There was no mention of decimals or fractions.
Basic arithmetic laws, such as the commutative and associative properties of addition and multiplication, were unheard of.
Equations? Even more so, they didn't exist.
Ye Yu believed that mathematics was a highly useful skill on Douluo Continent.
If someone had excellent math knowledge, they could easily live a respectable life as a bookkeeper in a hotel or restaurant.
Certainly, it would pay better than farming!
In addition, Ye Yu had also learned sketching in his past life, a skill completely unknown on Douluo Continent.
By teaching sketching, he could likely make money too!
And it wouldn't be a small amount!
After all, anyone learning art would certainly come from a wealthy family.
Ye Yu even imagined that, in the future, many nobles in Nuoding City would send their daughters to him to learn drawing.
Whether teaching mathematics or drawing, he would be incredibly important.
Plus, he would establish a teacher-student relationship with countless students.
Through this connection, as long as he paid a small protection fee, he wouldn't have to worry about being envied or exploited.
After all, there's no need to invite unnecessary trouble over a small amount of money.
Later, during his time at Nuoding Academy, Ye Yu began his teaching plan.
First, he organized a small classroom at home.
Then, he posted a notice to recruit students, offering to teach high-level mathematical knowledge that would make someone a competent bookkeeper.
The tuition was only one gold soul coin per year!
Naturally, no one believed it at first.
How could a child around ten years old have high-level mathematical skills and be qualified to teach others arithmetic?
In fact, many people ridiculed him, laughing at how a young child was so desperate for money.
After all, even Nuoding Academy's tuition was only two gold soul coins a year.
At first, Ye Yu's uncle, Wang Hongshan, didn't believe it either.
But Ye Yu's way of proving himself was simple.
He went to several of the most famous taverns in Nuoding City and challenged the bookkeepers who had mocked him to a math contest!
The result, of course, was that Ye Yu easily defeated them, crushing them in every round!
This left everyone astonished!
The entire city of Nuoding was in an uproar.
No one expected Ye Yu's math skills to be so extraordinary!
No one would turn down the prospect of profit.
Soon, parents were approaching him with respectful and eager smiles, enrolling their children in Ye Yu's math class.
As for how to get his drawing class started?
Ye Yu had his own brilliant strategy.
He first went to the front of the Spirit Hall in Nuoding City, where he waited for the beautiful female attendants.
Using his young age as an advantage, he sincerely offered to sketch portraits for the beautiful sisters for free.
Then, with his stunning, lifelike sketches, Ye Yu's drawing skills immediately astonished the attendants at the Spirit Hall.
Because of the close ties between soul masters and nobles, it didn't take long for Ye Yu's reputation as a drawing prodigy to spread through the noble circles of Nuoding City, where he was warmly pursued.
Many noblewomen and young ladies eagerly invited Ye Yu to paint portraits for them.
The price for each painting started at ten gold soul coins!
Thanks to Ye Yu's sudden popularity in the noble circles, many of these noblewomen and young ladies were the mothers and sisters of aristocratic male students at Nuoding Academy.
At first, the aristocratic male students were not happy with Ye Yu's sudden fame and attention.
But Ye Yu was no ordinary person.
As someone who had lived through five thousand years of civilization and been exposed to the explosion of information from the internet, Ye Yu knew exactly how to handle these little brats!
With his support, the students working at Nuoding Academy's labor department no longer suffered from the oppression of the aristocratic students.
This made the labor students look up to Ye Yu with admiration and gratitude.
The current leader, Chen Hu, even felt guilty and offered to give up his position to Ye Yu.
Of course, Ye Yu politely declined.
He was too busy!
After Ye Yu's exceptional sketching skills made waves in the noble circles, it didn't take long for nobles to send their daughters to him to learn sketching.
With his outstanding skills, Ye Yu realized that these students would have the potential to marry into higher-ranking noble families in the future.
This was a profitable venture!
As for the price for the drawing class, Ye Yu set it at one hundred gold soul coins.
Despite this, the class filled up in no time!
Through teaching math and drawing, Ye Yu earned more than three thousand gold soul coins in a year.
Initially, he had thought he might have to use some of the money to make connections.
But after making connections through sketching, with many noblewomen and young ladies among his acquaintances, Ye Yu no longer needed to spend extra effort on connections.
With the wealth he'd accumulated, Ye Yu also bought century-old ginseng and lingzhi mushrooms to speed up his cultivation.
Additionally, he purchased whale rubber.
This was a rare item that could enhance a soul master's physical constitution, allowing them to absorb soul rings beyond their limit!
At present, the power of whale rubber had yet to be discovered.
As a vitality-boosting medicine, century-old whale rubber was already more than sufficient.
As a result, few people would purchase thousand-year or ten-thousand-year whale rubber.
This made these more potent resins extremely cheap.
The thousand-year whale rubber cost only dozens of gold soul coins.
The ten-thousand-year whale rubber was priced at only a few hundred gold soul coins.
Shipping costs accounted for most of the price.
With enough money, Ye Yu began purchasing the century-old medicinal herbs and whale rubber in large quantities, taking small doses multiple times a day to minimize side effects and enhance his physical constitution.
Before he knew it, Ye Yu had turned eleven.
