Han Lie wanted to know the requirements for upgrading the system to level 3, so he took a taxi and went straight to the hotel room, lay down in the bathtub, and started adding more.

Shit, shit, shit…

Huh?

It doesn’t hurt as much as expected?!

Perhaps it's because the constitution and health reached 79 points in advance, so when upgrading strength and agility, there was only a slight swelling and pain, which was not a big problem.

Hey, it seems that next time you add attributes, you still have to add constitution and health first...

Well, of course, the special first priority cannot be changed for a hundred years!

The moment the basic attributes and secondary attributes were all raised to 79 points, a new prompt popped up in the panel——

[The attributes are up to standard and the consumption value is up to standard. Please upgrade the three knowledges and five skills to level 4]

Ha, the upgrade conditions are so simple?!

Han Lie was extremely happy and felt that the upgrade was just around the corner.

Three level 4 knowledges are worth 600,000 experience points, and five level 4 skills are worth 1 million experience points, for a total of 1.6 million.

And Han Lie already has three level 4 skills - craftsmanship, writing, and stock trading.

The actual consumption is less than 1 million.

Han Lie calculated that the three subjects of mathematics, finance, and economics require approximately 520,000 experience points.

The two magical skills of performance and deception are not far from being upgraded, and only require 180,000 experience points.

The gap is 700,000.

If you pay a woman, you can get it done with 350,000 yuan.

So Han Lie called Wang Tianqing to the hotel without even thinking about it.

"My performance has been good recently, thank you for your hard work."

President Wang’s charming eyes were like silk, and he was tired of acting coquettishly on his financial sponsor: “You only have one word of praise?”

"If you do well, you will be rewarded."

Boss Liege simply transferred 300,000 yuan to her, and then built up his momentum.

"Your contract has been extended, keep working hard.

In addition, although you will not be used for vacation, your salary will still be paid.

I’ll pay you two months’ salary in advance so that you can have a good year. How are you going to thank me?”

Wang Tianqing screamed so loudly that she almost went crazy.

He pounced directly on Han Lie: "I love you, I love you, I love you, I love you... Damn, suck!"

He bit Han Lie's face with saliva.

What follows is a story that cannot be written. Da Tiantian glowed with unprecedented enthusiasm, and her body temperature rose by at least three degrees.

That guy made Brother Lie so happy...

Of course, President Wang also paid a heavy price and was almost crushed to pieces.

With so many new powers added, it's really no joke.

No one thinks that core strength in the waist and abdomen is useless, right?

Boys, hurry up and practice!

Han Lie directly sent the remaining 50,000 yuan to Lou Xiaoxiao.

At that time, Lou Xiaoxiao was playing cards with Marco when she suddenly received a text message from Han Lie: "What is your Alipay account number?"

Lou Xiaoxiao typed quietly behind Marco's back: "xiaoxiaobaby520, why do you want to give me pocket money?"

Han Lie didn't reply to her.

Not long after, Alipay suddenly popped up a payment prompt. Lou Xiaoxiao opened it expectantly, her eyes suddenly widened, and she was completely confused.

She hurriedly hid in the bathroom and sent three question marks to Han Lie.

"???"

Han Lie: "To honor my sister-in-law, buy two pairs of silk stockings and some tonics for Brother Ma..."

Poof!

Lou Xiaoxiao laughed so hard that her whole body trembled as she typed and replied to three messages in a row.

"Dalang, is it time to take medicine?"

"Why are you so bad~~~"

"Stockings, do you like fishnets?"

Han Lie: "That's not what I meant, let alone that kind of person. Sister-in-law, you must never be sorry to my brother Ma!"

Lou Xiaoxiao was heartbroken and hurriedly sat on the toilet.

Dog man, so awesome!

…

After sending that flirtatious sentence, Han Lie ignored her again.

With the experience points in place, the system can finally be upgraded.

Start upgrading as planned.

The first one is mathematics.

At the moment of confirmation, there was a bang, and Han Lie's head shook heavily on the pillow, and his entire consciousness was completely confused.

Level 4 knowledge and skills are professional level.

In fact, this classification is quite vague and not easy to understand.

Take Brother Lie's level 4 skill as an example... Well, forget it, this skill is even harder to understand. Everyone knows it, but it is easy to learn but difficult to master.

To use an analogy of Level 4 deception...that doesn't work either. There are a bunch of straight men and otakus, so I guess you are all cuties who are always being deceived.

Anyway, it is a level where you can do well and apply it skillfully.

Specifically, the current flow of mathematical knowledge that Han Lie has accepted includes——

Real analysis, harmonic analysis, complex analysis, functional analysis II, abstract algebra II, commutative algebra, group theory, group representation theory, introduction to Riemannian geometry, homology theory, differential topology, mathematical methods in classical mechanics, Gromov-Witten

theory……

Good guy, Han Lie was so drunk that he rolled his eyes.

If his intelligence hadn't been raised to the limit of genius, he would probably have died long ago.

However, as uncomfortable as it is, the rewards are greater than expected.

The depth of mathematics knowledge at level 4 is average, but the breadth of it is terrifying.

Normally, undergraduates in the School of Mathematics at Peking University no longer take basic general courses by the time they are in their third and fourth years of college and start choosing a major.

For example, basic mathematics, computational mathematics, information science, probability statistics, financial mathematics, etc.

According to the broad categories of fields, there are also analysis and equation categories, algebra and number theory categories, geometry and topology categories, etc.

But the system doesn't care about that, it just instills all fields.

When he was halfway through the filling, Han Lie suddenly realized—fuck, it’s so shallow!

There is nothing wrong with getting a diploma, but if you want to do some research on your own in the theoretical field...it's useless.

But if you criticize me for not being good at Level 4 Mathematics...

That's not right.

With a broad and solid foundation, Han Lie can easily and quickly form combat effectiveness in any application field.

For example, quantitative analysis and financial engineering in the field of finance can be used by people who are really good at mathematics to play with.

Don't worry about people who are weak in mathematics, it won't be a problem for you.

For a period of time, Wall Street was rampant in quantification, and the recruitment targets were all graduates in mathematics, physics, statistics, and computer science. Masters in finance from prestigious schools were completely defeated.

What’s the coolest thing?

With a doctorate in mathematics and statistics, if you just learn a little bit of finance and computer knowledge, you will be a heifer riding a rocket in no time, becoming a manager for three years and a vice president for five years.

The king of subjects deserves his reputation!

Han Lie had just recovered a little and immediately made up his mind - next time, he should still give priority to upgrading mathematics!

The second upgraded subject is finance.

Finance is actually included in economics, but because of the particularity of the financial market, it is independent.

Unlike mathematics, which requires extremely high talent, it did not put any pressure on Han Lie.
