When he came to the lobby, he still exchanged a few words of greeting with Elder Cao of the Jindan Second Rank of the Dharma Training Hall, and Elder Cao took the lead and said: "There are many affairs in the Dongfang Sect, and Elder Ben will also open the skylight and say something bright: My brother-in-law Wang Anhuang has entered the Dao Eight Grades of cultivation, and now he is the top deacon of the patrol camp in Dongqi City, he wants to be the patrol camp leader of this Tianyang City, I wonder if the Dongfang Palm Academy can help?"

After a pause, he took out a few cheats and pushed them in front of Liang Feng, and said: "This is Cao's family heirloom secret book of fixation - there is a secret method for calculating pi, which can accurately calculate pi to nine decimal places! There are some other secret methods of fixing, such as the accurate spherical surface area calculation method......"

"Accurate method of calculating the surface area of the sphere, can you give me an approximation?" Liang Feng asked with a flash of eyes—so far, except for the jade slip he had seen in the 'Six Void True Illusion Array', he had never seen a method of accurately calculating the area of the sphere in other places, including the Divine Wood Sect Sutra Book Hall with countless classics.

"Dongfang Zhangyuan, you know that this embellishment technique is very useful, if you have advanced attainments in embellishing techniques, learning magic circles, spirit runes, and even exercises is twice the result with half the effort......!

Liang Feng pushed the secret book back, and repeated what he had said to Elder Wu of the Jingshu Pavilion before, and finally said: "Elder Cao, this camp is powerless, but this court is willing to exchange ten medium-grade 'Zimai Pills' for your approximate calculation of the spherical surface area, just say a rough idea." Of course, he knew how to calculate the surface area of the sphere, but now he was just curious if Elder Cao's purported precise algorithm was really accurate.

Elder Cao groaned and said, "If Elder Ben said it, the Eastern Masters still don't understand, then can't they go back?"

Liang Feng responded: "Of course. ”

Elder Cao roughly talked about his precise calculation method, that is, to cut the hemispherical surface into many isosceles triangles, and then these triangles can be pieced together into a large rectangle, the bottom edge of this large rectangle is half of the circumference of the circle through the center of the sphere, and the height of the rectangle is one-fourth of the circumference, so calculated, assuming that the radius of the sphere is r, then the surface area of the whole sphere is πr*πr, which is equal to π2*r2.

Finally, Elder Cao smiled and said, "Dongfang Sect, can you understand? This is quite a profound technique. Haha, haha, if you don't understand, Elder Ben can't say it anymore. After speaking, he put away the elixir and left.

Liang Feng watched Elder Cao's back disappear outside the door, and shook his head with a smile - of course Elder Cao's algorithm was wrong, although it seemed that there was no problem with the logic.

"mǎ lè Gobi, it's really curiosity that kills the cat! For this wrong formula, I spent ten sought-after elixirs!" scolded in his heart, Liang Feng said secretly: "Such a position in the camp is so popular, so many people grab it! Then who should I give this position to? There is no suitable candidate around me." ”

Although he told Elder Wu and Elder Cao that he couldn't decide on the candidate for this camp, in fact, he could decide completely - Madam Qi, the master of the Dongqimen Torture Hall, was obviously not going to reject the person he strongly recommended.

“...... Do you have any relatives and friends in the master's family? or the Qinqin family. ...... But how can I go to them myself?...... Forget it, the location of this camp is still a bit hot, and it is not necessarily a good thing to give it to the master or the relatives and friends of the Qin Qin family. After thinking about it for a moment, Liang Feng gave up his original idea. He planned to wait for another family to come to the door to make an offer—as long as the person who came was not an enemy, the character was acceptable, and the price offered was right, he was ready to sell the position.

In the next few days, there was an endless stream of people who came to the courtyard of Liang Feng to ask for help, and these requests were basically the elders and deacons of the various halls of Dongqimen, as well as the heads of other lower courts. However, because of the character or price of the candidate, he refused.

On this day, Qi Chenying hurried over and brought a message from Mrs. Qi: If he hadn't promised others the position of the Tianyang Courtyard camp, then Ye Lingmei, the head of the Dantang Hall, would take the position.

"Who?, Ye Lingjiao, the daughter of Dantang Hall Master Ye Qing?" Liang Feng asked in surprise.

After receiving an affirmative answer, he secretly said in his heart: "mǎ lè Gobi, it's really not that the enemy doesn't get together! Young master, I finally suppressed the urge to take revenge on Ye Qing's old witch, and now her daughter is here! mǎ lè Gobi, Ye Qing tortured the master so badly, do you want to take revenge on her daughter first, for example, sleep with her first, and then abandon her?"

This thought flashed through his mind, and another voice shouted: "Beast, big pervert, what kind of woman do you want to be on?"

"You know a fart!" This is for revenge, revenge! You know?" The voice of thinking in this life is louder than the voice of thinking in previous lives.

"Fart revenge! If you want to take revenge and find Ye Qing, what kind of ability is it to tempt and bully an innocent little woman?

Liang Feng's face turned red, and he shouted in his heart: "She is the daughter of Ye Qing's old witch, how can she be an innocent little woman?...... Shut up for me, young master!" viciously closed the memory area of his previous life that he was about to refute, and he muttered in his heart: "It's finally quiet...... Forget it, the master is definitely not willing to use this means to take revenge. Besides, how could such a noble person, young master, use such inferior means to take revenge?"

Qi Chenying, who was standing beside him, probably saw Liang Feng's expression change, and asked, "Young Master, what do you want?"

Liang Feng smiled: "There's no problem⊥ it's that Senior Sister Ye Lingji looks like a flower, young master, I can't help it......"

Qi Chenying's face changed slightly, she stepped forward to pull Liang Feng's arm, and said urgently: "Young Master, what you promised the young lady before, you also promised my cousin mine: in the future, you will no longer do the thing that robbed the people's girls to play, why is it going to change again? Besides, if Ye Lingmei has an accident in Tianyang Courtyard, her mother, Hall Master Ye, will definitely be the first to suspect Young Master!" After a pause, he said, "Young Master, you must not do that again!"

Liang Feng patted Qi Chenying's plump buttocks hard, leaned into her ear and whispered, "Ah Ying, of course I will listen to you, young master, and I won't do that again." Ah Ying, young master, I'm so obedient, how are you going to reward me?"

Qi Chenying became happy, her eyes became watery, she stood on tiptoe and bit Liang Feng's lip, and said in a nickname: "Badass, you badass! are all bullying your cousin!" and pulled Liang Feng's other hand and pressed it on his bore, and murmured: "Young Master, it's a long time without you......!"

After a touching and long-lasting exclamation "Ah-", Qi Chenying's whole body trembled for a moment, and she collapsed in Liang Feng's arms.

After embracing each other and enjoying a wonderful aftertaste, Liang Feng asked: "Ah Ying, it's just a message, you can use the Wanli communication symbol, why do you want to run in person?

Qi Chenying responded: "Originally, I used a communication charm, but I wanted to come to see the young master." After a pause, he said: "The Ji family seems to be very calm recently, that is, ...... It's Ji Yingshan, the head of Qishan Academy, who hasn't shown up for a long time - there was an important meeting a few days ago, and he was supposed to participate in it, but he didn't participate. Madame's guess is that Ji Yingshan should be seriously ill and about to fall. ”

Liang Feng nodded slightly, and said secretly: "Is this the reason why the Ji family didn't make a move on him?...... If he was Ji Yingxian, would he give up his original attack plan for this reason?...... No, and I won't delay it!"

Ji Yingshan only has a Jindan cultivation level, and his current age is not far from the limit of his lifespan, and it is expected that he will fall in the near future if he cannot advance, and it will not affect the original plan.
