Chapter 186 Mathematics

As soon as Jing Lan saw Li Motang, he said, "Don't pay attention to what the Sect Master said. Do whatever you want. Master is on your side."

Li Motang hurriedly thanked him, "Thank you, Master. In fact, I can understand what the Sect Master is thinking about."

Jing Lan praised, "You are still sensible."

Huang Feng was moved, this is the master!

Who knew that Jing Lan's face suddenly changed after he finished speaking, and snorted, "You have been out for so long. If nothing unexpected happened, you are not going to come back, right?"

"No."

Without waiting for Li Motang to explain, Jing Lan said again, "You also brought people back. Come here."

"Me?" Huang Feng realized after a while that this was said to him.

When he came over, Jing Lan looked him up and down for a while, then showed a satisfied expression, and said to Li Motang, "Disciple has a good eye."

Huang Feng: "?"

"?" Li Motang was stunned for a moment, and then hurriedly explained, "Master, it's not what you think."

"What?" Jing Lan and Huang Feng said in unison.

"What does it have to do with you!" Li Motang immediately said angrily to Huang Feng.

Seeing that the two were about to quarrel again, Jing Lan said angrily: "Don't quarrel, you two wait until I leave before quarreling, who are you showing off to!"

"Yes." Huang Feng responded, and Li Motang on the side was furious, but he didn't dare to quarrel again. He quietly kicked him and said angrily in his heart, "What did you promise, what does it have to do with you!"

Huang Feng pretended not to hear.

"Senior Jing Lan, I heard that my junior sister is back?" Suddenly there was a voice outside.

Hearing the voice, Xiao Nuan took a few steps and tried to wink at Huang Feng.

Huang Feng secretly looked at her and understood that it might be a love rival.

"What's wrong with your eyes?" Li Motang saw Xiao Nuan making trouble and sneered.

Xiao Nuan quickly covered her eyes: "I was looking for beads on the ground in the dark a few days ago. My eyes are tired and my eyelids keep twitching."

Jing Lan saw it, smiled slightly, and called the person outside the door in: "It's Tingzhang, come in."

"Yes." Gu Tingzhang heard the call, walked in, and after greeting Jing Lan, he said happily, "Junior sister, you are finally back."

Huang Feng thought that this person would give him a show of power, but he didn't expect that the other party would turn to him after saying: "This young master, I am Gu Tingzhang, nice to meet you."

Huang Feng returned the greeting with courtesy and asked Xiao Nuan, is it really a love rival?

Before Xiao Nuan answered, Jing Lan said to Huang Feng: "Gu Tingzhang is my senior brother's personal disciple. He grew up at about the same time as Mo Tang. He is one of the candidates for the future leader of Yuyuan Pavilion. My senior brother has always intended to match him and Mo Tang. Why don't you two compete?"

Huang Feng saw Jing Lan's half-smile expression and knew that this was not her pre-planned. She just saw Gu Tingzhang coming and wanted to watch the fun.

Gu Tingzhang was even more straightforward: "Disciple is willing."

Li Motang's face changed slightly: "Master, this is not good."

Jing Lan snorted: "As the saying goes, once a teacher, a father for life. As a teacher, I am just a little bit to help you check and test you. Isn't it too much?"

Li Motang was silent for a moment, and suddenly said: "Master, in terms of cultivation strength, Huang Feng is better than me, and my senior brother is not his opponent. In terms of knowledge, the students of Yunlu Academy will also give way to him. Don't embarrass my senior brother."

Huang Feng looked at Gu Tingzhang again, and added in his heart: "Although she looks extraordinary, she is still inferior to me!"

Jing Lan was a little surprised. Li Motang was actually speaking for Gu Tingzhang, and was actually on Huang Feng's side. How could she not see it?

And it can make the students of Yunlu Academy give way?

She was a little unconvinced, but she knew that Li Motang would not talk nonsense.

Gu Tingzhang didn't expect that his junior sister had changed so much after not seeing him for such a long time.

Jing Lan was curious and fanned the flames: "What are you afraid of? If you give up the position of the leader, then Tingzhang will most likely take over Yuyuan Pavilion in the future. It's good to temper his character now, at least let him lose with conviction. Besides, I remember that although Tingzhang is not good at poetry, he is very talented in mathematics."

"Mathematics?" Huang Feng was a little confused.

Jing Lan smiled and said, "Tingzhang, you come up with a question."

Gu Tingzhang nodded: "There is a merchant in Jiangzhou who wants to transport goods to Nanyang Town. He originally thought that there were evil spirits and the journey was difficult. It would take five days to arrive. Who knew that the journey was safe and he walked ten miles more than expected every day. As a result, he arrived one day earlier. How many miles is Jiangzhou from Nanyang Town?"

"..." Huang Feng was stunned. Is this the mathematics that Jing Lan was talking about?

Xiao Nuan was thinking hard and rubbing her head. Jing Lan smiled and said, "How is it? Can you answer it?"

"Yes, two hundred miles." Huang Feng muttered in his heart. Gu Tingzhang seemed a bit sinister. He asked him such a simple question. Was he calling him a primary school student in a roundabout way?

But when he looked carefully, Gu Tingzhang actually showed a bit of surprise. Could it be...

"Do you know the Pythagorean theorem?" Huang Feng asked.

"What?" Gu Tingzhang looked confused.

Seeing that he didn't know, Huang Feng began to talk nonsense: "Deep grooves and raised buttocks make people's hearts beat fast, shallow grooves and flat buttocks make people sleepy. This is the groove-butt theorem."

Gu Tingzhang was puzzled: "What does this... mean? What does this have to do with mathematics?"

"It doesn't matter." Huang Feng was a little embarrassed, muttering in his heart, "I'm just afraid to say something relevant, you can't accept it."

"How about we try swords?" Huang Feng took the initiative to suggest, he felt very kind, if he taught some spatial geometry and calculus, Gu Tingzhang would be entangled by the inner demon day and night in the future.

"Wait, I have another question!" Gu Tingzhang seemed unwilling to give up, "Now there is a cage with chickens and rabbits in it, count them, there are fourteen heads, thirty-eight legs, ask..."

Before he finished, Huang Feng said: "Nine chickens, five rabbits, let's go, let's go to the sword test field."

Gu Tingzhang: "..."

Huang Feng slipped away first, bullying people will make you feel guilty, and now this guilt is so great that he can't bear it.

Li Motang smiled slightly: "Master, are you going?"

"You girl!" Jing Lan snorted, "Go, why not, I'll go call the sect master."

Huang Feng came to the sword test site, and soon, Gu Tingzhang followed, and Li Motang followed with Xiao Nuan.

Then came Jing Cang and Jing Lan, and the two were talking.

"You picked it, didn't you?" Jing Cang said angrily.

"Aren't you curious?" Jing Lan smiled, "And Motang has clearly refused, it's time to hone your apprentice."

Seeing that everyone was there, Huang Feng took it as a necessary step to kidnap his wife, and smiled at Gu Tingzhang: "Please teach me, brother Gu."

Gu Tingzhang nodded, and his silly look changed a lot from the silly look when he was taking the math test just now. The green robe on his body moved without wind, and the sword jumped out of the square inch object, the sword body trembled slightly, and made a clear sound.

When the sword was unsheathed, Gu Tingzhang's sword intent penetrated the heaven and earth, and it turned out that he had entered the state of unity.

"It turns out that this is just a joke." Huang Feng looked solemn.

Gu Tingzhang drew his sword and thrust it out, and the sword net enveloped Huang Feng.
