"Damn it, why are you wrong again? Could it be that my research direction is wrong?"

"Impossible, this is impossible!"

"What's wrong?!"

A white-haired old man from the Mediterranean was crazily pulling the only hair on his head, and he pulled several of them. I don’t know if he would regret it after he woke up.

"Shit, why would anyone disturb me at this time?!"

The old man took out a crystal ball with a flashing light from his pocket in a little annoyed.

"Someone is here to run for a theory teacher?"

"Damn it, if I don't have real talent and knowledge, I will definitely use fireballs to burn you into slag!"

The old man put away the crystal ball.

And at the same time.

In the Dean's Office of Hope College.

An old man with a short hair with a little hair, frowned and looked at the portrait displayed on the crystal ball: "This brat, finally, is he willing to show up?"

"I'm also here to apply for a theory teacher, just his three-legged kung fu?"

...

"Brother, big brother, no, can you tell me how you calculated this?"

"Brother, brother, do you smoke?"

"Brother, sit, sit!"

The young man in a magic robe served Fang Bai comfortably like a little fan. He first took out a pack of cigarettes, then took out one and handed it to Fang Bai's mouth, and then his fingers were tucked and a small twelve twelve appeared on his fingers.

He let Fang Bai sit in his position, and then bent down respectfully.

Smelling the good tobacco smell, Fang Bai took a deep breath of cigarette.

As a teacher who is proficient in eating, drinking, and having fun, Fang Bai never thinks he is a good person...

"I'm so fucking, so fucking me!"

Looking at Fang Bai's extremely enjoyable expression, Wu Meow couldn't help but feel a little moved.

"If you smoke a ghost, don't see how useless you are!"

Fang Bai curled his lips in extreme disgust.

He looked at the young man in front of him with satisfaction.

"This question is not difficult!"

"For questions like this, there are generally unified problem-solving steps. The problem-solving steps are very simple!"

"The first step is to review the question!"

Fang Bai took another breath of cigarette with a pleasant sip. The young man's cigarette seemed to be soaked in magic. It felt very pleasant to smoke, and he felt like he was floating in the air... His whole body was like running on a hot spring, warm.

"Review the question?!"

The young man's eyes lit up as he listened to Fang Bai's words.

He quickly took out the paper and pen and recorded Fang Bai's words.

"Yes, that's the question. What is question review?!"

Fang Bai's fingers hit the table a few times, as if he had found the feeling of explaining physics problems to students on Earth.

“What is question review?”

Fang Bai repeated it.

Fang's aura suddenly rose. As a senior people's teacher on earth, his teaching level is unquestionable. It can be said that in the classroom, he is the absolute master.

The young man looked at Fang Bai with concentration like a good baby.

"That is to understand the meaning of the question, so in the process of reviewing the question, we must find something very important!"

"That's what the questioner wants us to do?!"

Fang Bai's voice was very contagious.

"Then let's look at this question!"

Fang Bai focused his attention on the paper on the desktop, and then...

"Well, this question..."

As an excellent teacher, do you think someone on our side will not be able to speak if he is illiterate?

Innocence, hum!

"You read the question again now and let me see if you understand what I mean!"

Fang Bai looked at the young man and said.

"Oh, OK!"

The young man nodded quickly, looked at the question on the paper, and read it carefully: "Suppose a fire magician met a wind wolf in the forest, and the distance between the two was ten meters. In order to kill the wind wolf, the fire magician could only use the fastest fireball technique. It is known that the wind wolf's speed is eight meters per second, while the fireball's speed is ten meters per second."

"First question, how many seconds does the fireball take to hit the wind wolf?"

"The second question is that the magician's speed is six meters per second. If it takes three fireballs to kill this storm wolf, when the fireball hits, the magician will immediately release the next fireball. How many seconds will the whole process take?"

"The third question is, after the fireball is released, the power will be reduced by one dimension for every ten meters of flight. The power of the initial fireball is one hundred latitudes. What are the power of these three fireballs?"

Fang Bai looked at the young man with a serious face, "Did you understand?"

"Ah?" The young man was a little confused.

"Don't understand yet?"

Fang Bai frowned.

"Continue reading!"

"Oh, suppose a fire magician met a wind wolf in the forest. The distance between the two is ten meters. In order to kill the wind wolf, the fire magician can only use the fastest fireball technique. It is known that the wind wolf's speed is eight meters per second, while the fireball's speed is ten meters per second..."

"Do you understand?"

"A little bit!"

"Then read it!"

"Suppose a fire magician met a wind wolf in the forest, and the distance between the two was ten meters, in order to be able to kill the wind wolf..."

"Do you understand?"

"I understand!"

Fang Bai nodded with great satisfaction.

The deceased cat on the side looked at this scene with shock. Damn... Is this cat okay to change to this cat! Isn't it just fooling people!

Is this young man so low in IQ?

This person who stepped on the horse is even more stupid than Lord Meow!

"Just understand, so let's look at it. In fact, this problem can be classified as a very simple pursuit problem!"

"And what is the most important thing in this pursuit problem?"

Fang Bai asked again.

"Speed, and...time!"

The young man said quickly.

"Yes, speed, still time!"

"This is the second step in our problem-solving steps, look for it!"

Fang Bai pretended to be so sophisticated and took another breath of cigarette. Do you know what the teacher’s basic skills are? That’s right, it’s just a fool, the teacher’s mouth, a lie!

What does the teacher rely on to make a living? He only depends on his mouth to make a living!

So the teacher's oral skills are generally very good, after all, his tongue is flexible... Well, comrades have sat down and drove.

"Look?" the young man muttered and quickly recorded it.

"Yes, just look for it!"

“What to look for?!”

"Find known conditions, and there are unknown conditions!"

Fang Bai shook the ash, enjoyed his facial expression, and took a deep breath of cigarette.

"Known conditions? Unknown conditions?"

The young man quickly copied it down again.

"What are the known conditions? The known conditions are the conditions that the question has already told you, such as the speed of the wind wolf, the speed of the fireball, and the speed of the magician. These are all the conditions that the question has already told you! The conditions that the question has already told you are called the known conditions!"

"So, what are unknown conditions?"
