Liang Feng looked at it and smiled to himself, if it was in his previous life, no one would have asked him such a simple question as a great mathematician. However, in this world, he still pretended to think for a moment and gave ideas and answers to solve the problem.

The guys on the side saw that Liu Qingqing was gentle with Liang Feng, and they all sneered, saying that Liang Feng knew how to embellish a fart, and he must have deceived the little girl to play, and told Liu Qingqing not to be fooled.

Liang Feng didn't take the guy on the side in his eyes, so he didn't get angry, and said, "Liu Daoyou will definitely understand when he goes back and thinks about it." He knew that the calculation of this combination was useful in the miniature transformation circle on the spirit rune, and he had worked hard to get the drawing technique of the hidden talisman when he was in the spirit stone mine, and he had studied it in depth and understood the basic principles of the spirit rune drawing.

Liu Qingqing was blessed again, and said with a smile: "Well-thank you, Senior Brother Liang!" She left with her partner Yin Ying, who came with her. The guys greeted them warmly and told them to come to the shop when they had time.

Liang Feng looked at Liu Qingqing's graceful back, thinking of her flower-like smile, and felt quite pity in his heart. He knew that they were not very old now, and their cultivation had not reached the Peiyuan Nine Grades, so they didn't have to accept customers, but when they reached the Pei Yuan Nine Grades or reached a certain age, they would be auctioned off for the first night rights, and it was said that they could sell quite a lot of spirit stones—because there were quite a few monks who believed that the Yuan Yin of the Peiyuan Nine Rank Female Monks was a great tonic, which was very beneficial for cultivation and advancement.

"What else can I do if I am a fallen person at the end of the world?" he sighed again in his heart, collected his mood, and went back to the house to write the secret book of the 'Calculation of Spherical Surface Area', and his two thousand registration fee was counted on this secret book.

On the second day, Liang Feng came to Zhao's shopkeeper with a book of taboo cheats, and said: "Shopkeeper Zhao, the senior agreed, this is the 'spherical surface area calculation method' cheats, pay the money with one hand and deliver the goods with the other! You can inspect the goods immediately." ”

Shopkeeper Zhao raised his hand to receive the cheats, and when he saw that Liang Feng pressed the cheats and didn't let go, he shrank his hand in embarrassment, and said with a smile: "Alas, Liang Daoyou, the old man of the two thousand six high-grade spirit stones was ready, but last night, a friend urgently used the spirit stones and borrowed some, and now there are only two thousand four spirit stones......

Liang Fengpi stopped smiling, put the cheats into his skin, and turned around to leave.

"Slow...... Liang Daoyou, please stay, the old man really only has so many spirit stones, how about using this eighteenth-generation family heirloom jade slip to offset the insufficient part?" Zhao shopkeeper shouted, he took out a bag of spirit stones and a simple jade slip.

"Liang Daoyou, look at this jade slip, it is all Tuqin color on it, it is definitely an eighteen-generation family heirloom, it is definitely an antiquity, but there is no ...... in it , Oh, you are a monk of the Peiyuan period, and you don't have divine consciousness yet, so you can't read the jade slip. He saw Liang Feng pick up the jade slip and put it on his forehead, and hurriedly explained.

Liang Feng's expression changed, and he looked embarrassed, and said: "Okay, that's it! The senior said to give me two hundred spirit stones for the running fee, I don't want this running fee, exchange this jade slip, this jade slip really looks like an antiquity, I like it!" He put the spirit stone and the jade slip into the leather bag around his waist and turned around to go.

"Slow! Liang Daoyou, the old man hasn't inspected the goods yet. Shopkeeper Zhao shouted again.

Liang Feng stopped and said with a smile: "That senior said, there is no problem!" He stood at the door and waited for Zhao's shopkeeper to inspect the goods, and at the same time activated a communication charm prepared in secret.

Shopkeeper Zhao lifted the taboo and opened the secret book of the 'Sphere Surface Area Calculation Method', looked at it for a while, pondered for a while, looked at it for a while, pondered for a while, and so on, he suddenly laughed and said: "I see, I see!

Liang Feng smiled silently, the 'Sphere Surface Area Calculation Method' secret book is written in the previous life Archimedes' calculation steps, of course, it is exquisite, and the final calculation result is that the surface area of the sphere is equal to two-thirds of the surface area of the smallest inscribed cylinder of the sphere. Actually, the volume of the ball is also equal to two-thirds of the volume of the cylinder, but this formula is not written into the cheats.

Shopkeeper Zhao closed the cheats and asked with a smile, "Is it really entrusted to you by a senior in the middle stage of the Dao?" His smile was a little weird.

Liang Feng said: "Of course, he is estimated to be coming soon!"

As soon as the words fell, a spirit pressure came, and a voice asked, "Who activated the spirit rune, and what?"

Shopkeeper Zhao suddenly changed color.

Liang Feng quickly opened the door, ran out, and said to the monk on the flying magic weapon Swift Wind Boat parked in the sky: "Senior, it was the messenger that the kid accidentally activated, nothing is wrong. He held a bag of spirit stones in his hand and held it above his head.

The monk beckoned, and the bag automatically flew into his hand, and after checking it, the bag disappeared, and said, "It's okay, don't activate the alarm communication charm." With that, he left.

Liang Feng also rushed away, and said secretly: "Fortunately, I spent a lot of money to buy two alarm communication charms, as soon as this spirit talisman is activated, the deacon of the patrol camp who maintains law and order in Dongqi City will come to check it." In the end, the shopkeeper Zhao really had the intention of killing people and taking money,...... Alas, the strength is insufficient, and it is a sin to be conceived!" He sighed, and strengthened his determination to be admitted to Dongqimen.

Touching the spirit stone in his skin, Liang Feng turned around halfway and headed in the direction of the mountain gate of Dongqi Gate - he wanted to go to the entrance Danbi registration office in Dongqi Gate to sign up immediately. After passing through half of the city, he queued up for a long time at the registration office, and then handed over two thousand high-grade spirit stones in exchange for a Danbi identity jade plate.

Touching the deflated skin again, Liang Feng breathed a sigh of relief and laughed at himself-Niang Xipi, she is so timid now, and she is not at ease with two thousand spirit stones on her body.

When he returned to Danpu, the sunset was full of sky, Liang Feng's mood was also very good, he finally signed up, and the next step was to quit his job, and then find a place to concentrate on studying alchemy for half a year, and then participate in Danbi. When I entered the Danpu, I found that the Danpu was very lively, and the guys were talking about it one by one, and then took a closer look, it turned out that Yin Ying and Liu Qingqing were here.

When Liu Qingqing saw Liang Feng coming back, her eyes lit up, and she shouted up, "Senior Brother Liang......" Her voice was still so shy and timid.

When the guys saw that Liu Qingqing ignored them, they coaxed and said strange things, such as 'When you come to the lover, you lose your friends' and so on.

Liang Feng was very unhappy in his heart, but he didn't want to see those guys in general, and said, "Liu Daoyou, please talk outside." He walked out of the shop and walked to the mouth of a small alley.

Liu Qingqing's face was flushed, and he stood more than one step away from Liang Feng, and said softly: "Senior Brother Liang...... , Little sister, I heard that senior brother, you want to sign up for the entry to Dongqimen?"

Seeing Liang Feng nodded, she took out a small bag of spirit stones from her arms, and as if she wanted to hand it over but didn't dare, she lowered her head slightly and said, "I have often asked your senior brother to embellish the technique for many days, little sister...... Little sister, I have accumulated some spirit stones, as a fee for consulting the embellishment......" Speaking of the back, the sound was inaudible, and he raised his head and said: "I heard that the registration fee is two thousand high-grade spirit stones, but ...... But...... I only have so many spirit stones, senior brother...... Senior brother, you ...... Don't dislike it!" she took a deep look at Liang Feng, stuffed the bag of spirit stones into Liang Feng's arms, turned around and trotted away, her skirt fluttering.

Liang Feng untied the bag, and there were fifty-two high-grade spirit stones that still had body temperature in it.

He looked at Liu Qingqing's graceful back, opened his mouth to say something but couldn't say anything, only felt that a breath rose from the bottom of his heart, blocking his throat and nose, and his eyes gradually dimmed-

You must have suffered a lot of grievances, how much caution and a smile you have to be with these spirit stones to earn, why did you give me all of them as a lowly alchemy worker?

Everyone thinks that it is whimsical and impossible for me to be admitted to Dongqimen, why do you trust and support me so much?

You gave me all you have, all the spirit stones, but you're still afraid of being disgusted by me?

......

I thought of the former junior sister, and I used to sweetly call myself 'senior brother, senior brother', but later in order to marry into a wealthy family, I trampled on all my dedication like mud!

Two lines of tears slipped down!

Liang Feng wiped away the tears vigorously, took a deep breath, and said secretly: "Qingqing, Qingqing-I will definitely rescue you from the 'Yiyulou'!" He thought, after all, there is still someone in this world who cares about him sincerely.

——

On the way back, Yin Ying asked: "Qingqing, have you given all the spirit stones to the guy surnamed Liang?" Alas, what's so good about that guy? Although he is long and pleasing to the eye, how can he be admitted to the Dongqi Gate? Isn't it a waste to give him the spirit stones? Are you really stupid, those spirit stones might as well go to please the deacon in the building, and life will be better, and if you don't give them to any disciple of the Dongqi Gate, maybe you really meet someone who is sincere to you?"

Liu Qingqing's heart was gloomy, although he didn't have to sleep with guests in the 'Yiyu' building now, it was common to accompany wine and sing songs, and he had also seen a lot of monks in the Dao Initiation Period and many disciples of the Peiyuan Period of Dongqimen, but when everyone looked at themselves, there was always desire and contempt hidden in their eyes, the difference was just a difference in the depth of concealment, how could anyone be sincere to themselves? Even the guys in the store didn't feel nobler than themselves and Sister Yin? Only Senior Brother Liang looked at him with equal eyes......

She was silent for a moment, and then argued: "I often ask Senior Brother Liang for the technique, and I should calculate the cost of apprenticeship......

Yin Ying smiled and said, "You're still strong-mouthed! What kind of embellishment does the guy from Danpu know? Isn't it because we Qingqing is beautiful and looking for a chance to talk to you?"

Liu Qingqing said seriously: "Senior Brother Liang, he really didn't want to talk to me, he really knows how to embellish, I feel that his embellishment technique is better than Deacon Bao in the late stage of his initiation!" "Deacon Bao is a deacon of the Dongqimen Jingshu Pavilion, and he once went to the 'Yiyu' building, at that time, Yin Ying and Liu Qingqing were all accompanying the wine and singing, and I heard Deacon Bao give a disciple guidance on the technique.

"Okay, okay, Qingqing, even if your Senior Brother Liang is very good at embellishment, and he is also handsome, sister, I also like to see him, but what's the use of this? He is just a Danpu guy, can he have tens of thousands of high-grade spirit stones to redeem you? Take another 10,000 steps back and say, even if he is admitted to Dongqi Gate, will he still remember you at that time? Will he still remember that you gave him all your spirit stones?"

Liu Qingqing's face became more and more pale.

Yin Ying said again: "Qingqing, sister, I don't want you to be deceived by those men! You said that your Senior Brother Liang, if he has tens of thousands of high-grade spirit stones, will he think of you and come to the 'Yiyu' Building to redeem you?"

Liu Qingqing's eyes were hazy, and she said in a trembling voice: "I...... I...... I don't know. Two crystal teardrops crossed his smooth cheeks and fell to the ground.
