At this time, listening to the various data from the person in front of him, Wu Dong was already sweating profusely. [. Lots of good]

He didn't expect that there was such a perverted spiritual cultivator in this world, and it was just enough to be able to see his cultivation, and he could even see the speed of his spiritual power flow, strength, speed, and the release speed of his spiritual skills, which was simply a monster.

For the first time in history, Wu Dong was frightened like this by other people's demons.

No wonder the people in the spiritual courtyard would call the middle-aged man in front of him crazy, it was really crazy, at this moment, Wu Dong really felt it deeply.

At that moment, in the face of the middle-aged man's smiling gaze, Wu Dong relieved himself and asked, "Senior, who are you?"

"Hehe..."

Hearing this, the middle-aged man in front of him was immediately amused by Wu Dong's expression, and at that moment, the latter pointed to the jade in Wu Dong's hand and said, "If you have enough right to send this thing to your teacher Lu Bai, who do you think I will be?"

Hearing this, Wu Dong immediately understood, thinking that Lu Bai had mentioned more than once that he had asked his teacher to get a letter of sponsorship from the Xiaoyao Zhongling Academy for Wu Dong, although Wu Dong's cultivation was not needed, but the students who had the sponsorship letter and the students who did not have the sponsorship letter were obviously treated in the Xiaoyao Zhongling Academy.

Students with sponsorship letters, like Wu Dong, have already been able to see their future teachers among the students in advance.

Immediately, after Wu Dong groaned slightly, he immediately shouted respectfully at the middle-aged man: "Boy Wu Dong, I have seen my master." ”

Regarding Wu Dong's title, the middle-aged man suddenly pursed his lips, and then said: "I'm so old, if you can pass my test, just call me teacher in the future." ”

"If you can't pass, even if you were Lu Bai's student and Wu Gang's son before, then you should go elsewhere!"

"Test?"

Hearing this, Wu Dong was stunned, he didn't expect that there would be a test when he saw his teacher's teacher, and then Wu Dong suddenly sighed, and then knew that it was not a simple matter to successfully worship under the door of Lu Bai and his father's teacher.

Immediately, Wu Dong walked into the tree house at the signal of the middle-aged man.

The tree house has a lot of space, but the furnishings are very simple.

As far as Wu Dong's eyes go, in addition to a large number of books, he can still see books, and the scene in front of him, even Wu Dong, who used to be a scholar, is secretly speechless, and then secretly slanders the peerless powerhouse in front of him is still a scholar?

In addition to books, there was also an enchantment screen in the middle of the treehouse that immediately attracted Wu Dong's attention. [.cc]

Is that...

Arithmetic?

Seeing the numbers on the screen, Wu Dongdu almost screamed.

Immediately, Wu Dong suddenly remembered that Lu Bai had mentioned to him that the latter's teacher knew arithmetic, but Wu Dong didn't take it seriously at that time.

With his gradual understanding of this world, he has not heard of anyone who can do arithmetic, and I am afraid that this world is a matter of circular spheres, and few spiritual cultivators know about it.

Although this world advocates cultivation civilization and does not have the science of Wu Dong's original world, many of them still think that the sky is round and the calligraphy is round, but judging from the current situation, it is obvious that Wu Dong underestimated the wisdom of the spiritual cultivators in this world.

There is really someone here who is good at arithmetic in his world, and he also has a deep attainment.

In addition, cultivators who are good at arithmetic are able to skillfully integrate arithmetic and cultivation, which makes arithmetic and cultivation touch an extraordinarily beautiful spark.

Originally, Wu Dong was still frightened why the middle-aged man in front of him could see all kinds of data in his body at a glance, but in Wu Dong's mind, it must be related to the arithmetic in front of him.

Perhaps in the eyes of middle-aged people, everything in Wu Dong's body is already data.

These can be seen from the one-dimensional quadratic equations, binary quadratic equations, and so on on the screen in front of you.

Thinking of this, Wu Dong's eyes suddenly became hot, you know, he is extremely good at arithmetic, if he can integrate arithmetic and cultivation together, then when fighting with the enemy, all the data in the enemy's body is not in control, and controlling the enemy's data means controlling the enemy's weaknesses.

In this way, before fighting the enemy, you are already invincible.

At the moment, while Wu Dong was staring at the arithmetic on the screen, he couldn't help but calculate the answers to those equations in his heart.

Seeing that Wu Dong was attracted by the arithmetic on the screen, the middle-aged man's face also showed a hint of surprise.

Because of Wu Gang's matter, he didn't want to teach any more students, but his idea was suddenly broken by Lu Bai's news.

It's just because Lu Bai once told him that there is a young genius in Qingyan Xiaoling Academy who is suspected of being good at arithmetic.

At that time, he still didn't believe it, and he didn't take it seriously, but now it seems that what Lu Bai said is very likely not to be a lie.

Judging from the performance of the young man in front of him, he is very likely to know arithmetic, and thinking of this, the middle-aged man's face is also a little expectant.

Therefore, he will allow Wu Dong to meet Wu Dong, and he will also allow Wu Dong to enter the bookstore.

These, Wu Dong also has some guesses in his heart, he can stand here, not because he is Lu Bai's teacher, nor because he is Wu Gang's son, but because the other party thinks that he is very likely to be good at arithmetic.

At the moment, Wu Dong looked at the equation on the screen, and his mental arithmetic was faster.

If you want to get the attention of others, you naturally need to show the strength to make others look sideways, although he still doesn't know the test of this middle-aged man, but Wu Dong feels that it should be related to the equation in front of him.

Immediately, Wu Dong gritted his teeth, he wanted to calculate the answers to all the equations in the fastest time, he was betting, betting that this was the test.

Seeing Wu Dong's performance, the surprise on the middle-aged man's face became more and more, and Wu Dong's preoccupied appearance was already showing him that the latter seemed to be really good at arithmetic.

At the moment, he is also a little uncertain.

Now, judging from the current situation, Wu Dong really has a good chance of being good at arithmetic, otherwise, the latter would not be attracted by the arithmetic he wrote on the screen at a glance.

But in this world, except for him, almost no one understands what that means, because this thing is summed up by his enemies, and he just carries it forward.

Therefore, when Wu Dong was mentally calculating the answers to those equations, the middle-aged man looked at him quietly and did not bother.

After a while, Wu Dong finally calculated the answers to all the equations, and then Wu Dong suddenly smiled apologetically at the middle-aged man and said, "Senior, I'm sorry, I'm distracted." ”

"Now that I'm ready, can you tell me what your ordeal is?"

Hearing this, the middle-aged man waved his hand absently, and then pointed to the arithmetic on the screen and said to Wu Dong: "That's your test?"

Hearing what the middle-aged man said, Wu Dong immediately smiled.

Sure enough, as he expected, he bet right, but Wu Dong naturally wouldn't show these emotions, and at that moment he pointed to the arithmetic on the screen and asked in an uncertain tone: "Senior, do you say that this is my test?"

"Yes, as long as you can write all of their answers, you are eligible to be my student. Smiling slightly, the middle-aged man said softly.

Hearing this, Wu Dong was secretly happy in his heart, and then at the signal of the middle-aged man, Wu Dong walked to the front of the screen, pretending to think for a moment again, Wu Dong used spiritual power to write the answers to all the equations on the screen.

This time, it was the middle-aged man's turn to be surprised, he didn't expect that Wu Dong would really be able to write the answers to all the equations.

It seems that just like the news from Lu Bai, Wu Dong has a strong talent in arithmetic.

But no matter how talented you are, you can't understand this, right?

However, when he thought of the strange aura in Wu Dong's soul, the middle-aged man was immediately relieved.

Thinking of this, a satisfied smile suddenly appeared on the middle-aged man's face, he has been here for so many years, and today he finally found a very interesting junior.

Wu Dong didn't know what the middle-aged man thought, at this time, he solved all the arithmetic, and then his heart moved, and he wrote a few functional equations on the screen at random.

"What is this?"

Sure enough, as Wu Dong thought, he had just written the function equation, which attracted the attention of middle-aged people.

"This is the equation of the function!" Wu Dong smiled at the inquiring gaze of the middle-aged man.

"Functional equations?"

The middle-aged man heard this concept for the first time, and he stared at the functional equation on the screen for a moment before asking, "Can you teach me this?"

Hearing this, Wu Dong was stunned, he didn't expect that the middle-aged man who was an elder would ask him directly, and at that moment Wu Dong's heart was respectful to the middle-aged man in front of him, and then he said: "The senior speaks, the kid naturally doesn't dare to hide his secrets, but the seniors are powerful, if you don't dislike it, the kid is willing to discuss this arithmetic with you." ”

After getting Wu Dong's affirmative answer, the middle-aged man also smiled with relief, there are few young people like Wu Dong who knows how to be polite.

Immediately, after a moment of silence, he also said: "You don't need to call me a senior, although many years have passed, but I can still remember my name, the spiritual cultivators of the spiritual academy call me Li Lao or a madman in private, and you can call me Master Li in the future, because my name is Li Xiaoyao!"
