One day more than 20 years ago, Gordon opened a blacksmith shop in Shezhou, at the foot of the Yellow Mountain, because of his excellent craftsmanship, fair prices, and there was no other blacksmith shop in the city, so the business was very prosperous and famous. One day, Gordon was busy, suddenly seven people from the Huangshan Beidou faction came into the store, gave him a sketch of a box, and asked him to make one according to it, Gordon looked at the sketch, the box was very large, three feet in length, width and height, and the wall thickness required five inches, what kind of huge and heavy iron box it was! And the strangest thing was that this box required seven key holes, and seven different keys had to be inserted into it at the same time to open the lid.

This is not too high a requirement for Gordon, ask for details, negotiate the price, and then start to prepare. A month later, Gordon finally made the iron box, and the seven people came to the store together to take the box away, and Gordon said to the leader surnamed Qin: "Qin Daxia, this iron box is extremely accurate, and it is required to be parked extremely smoothly, and if it is a little crooked, it will not be able to open the lock, I have to follow to debug and guide you to place it." The man nodded, and took him up to the Yellow Mountain and came to the Tiandu Peak, the headquarters of the Beidou Sect.

The iron box was placed in the room of the leader, Senior Brother Qin, and Gao Deng was busy with it, putting the box in the right place, and after the debugging was completed, he collected the money and went down the mountain.

The seven people who made the box are the seven sons of the Big Dipper, the eldest brother Qin Tianshu, the second brother Zhong Tianxuan, the third brother Wei Tianji, the fourth brother Song Tianquan, the fifth brother Feng Yuheng, the sixth brother Zhu Kaiyang, and the seventh brother Fan Shaoguang. At the beginning of this year, Zhou Zilong, the master of the seven, died at the age of eighty-eight.

Before Zhou Zilong died, he summoned his seven sons to the bed and said, "You seven brothers, you must keep in mind one sentence, 'If you divide you are weak, if you join you, you will be strong.'" 'After I leave, you must listen to Senior Brother Qin's words. The seven of them said in unison, "Yes, Master." Zhou Zilong took out a thin booklet from his arms, handed it to Qin Tianshu, and said: "This secret book of "Mixed Yuan Seven Star Divine Skills" is jointly kept by the seven of you to practice together, Tianshu, Tianxuan, the two of you have practiced to the seventh and sixth level respectively, and the responsibility of guiding the junior and younger disciples to practice will fall on you, but you must not have any selfish distractions and treasures. Qin Tianshu and Zhong Tianxuan responded in unison: "Yes!"

Zhou Zilong stayed for a while, and said: "This mixed yuan divine skill was created by me in my later years, and it is the essence condensed by my lifelong immersion in the ocean of martial arts, but because time waits for no one, I have not had time to point out and correct many imperfections in the divine skill mental method, I just hope that the seven of you senior brothers will unite as one, brainstorm, and constantly summarize and improve in the cultivation process, so that it will become the Dinghai Divine Needle that has laid the foundation of my Beidou Sect for thousands of years." The seven of them replied in unison, "Yes!" ”

After another long time, Zhou Zilong said: "Let's all go out, Yuheng, you stay." After the sixth son went out, Zhou Zilong said to Feng Yuheng who was at the head of the bed: " Yu Heng, among the seven brothers, you are the most upright and unselfish, I have here a mantra of the Mixed Yuan Divine Skill to hand over to you, in the first seven layers of the Mixed Yuan Gong, there is not much difference between the mantra and the cheats, on the eighth level, the mantra becomes the auxiliary of the cheats, you take good care of it yourself, if your eldest brother and second brother want to practice to the eighth level, you have to help this mantra, but if they refuse to teach and guide your brothers to practice this kung fu, you don't have to pass on the mantra to them, destroy the mantra after memorizing it, remember, remember. After speaking, he closed his eyes and drove the crane fairy.

After dealing with the master's funeral, the seven sons gathered together to discuss the cultivation of divine skills, Feng Yuheng told the master's last words, and the master brother Qin Tianshu said: "Fellow disciples, please rest assured, I will never have any selfishness, how much I know, how much I understand, I will share it with the six brothers without reservation." Zhong Tianxuan said: "This mixed yuan magic skill is too difficult and obscure, if the seven of us practice each, the progress must be very slow, and even go astray, I propose that every time you practice, everyone should get together, guide and supervise each other, and improve each other." The other six said hello in unison. Master Brother Qin Tianshu said: "Since it is a joint cultivation, it is obviously inappropriate to put this secret book on me, everyone said how to store this secret book?"

Everyone thought about it, and finally came up with a way to store the cheats: "Make a big iron box with only seven keys, one for each of the seven keys, and only when the seven brothers are present at the same time can they open and take out the cheats for cultivation." So, the seven men found Gordon and made an iron box and put it in the elder brother's house. The seven brothers opened the box every three days and took out the cheats to study.

Master Brother Qin Tianshu is really as he said, he is very enthusiastic to guide the six junior disciples to practice, he is really more careful and patient than the master, Feng Yuheng asked everyone and had no opinion, so he will inform the senior brother of the eighth and ninth mantras.

But one day more than a year later, when the seven of them opened the box together, they found that there was nothing inside, and the secret book was gone! The seven people were taken aback, stunned, and looked at each other, and then carefully checked the box, and did not see anything suspicious, and then checked the house, and found no clues, so that the well-guarded martial arts secret book disappeared silently under the noses of hundreds of masters and apprentices in Tiandu Peak of Huangshan Mountain, as if it had never existed in the world at all.

The seven people were unwilling and arrested everyone on Huangshan for careful questioning, but they still couldn't find the slightest clue. Gradually, there is a saying among the six brothers below Zhong Tianshu that the senior brother has already obtained the mantra and practiced the magic skills, so he destroyed the secret book and did not let the junior brothers practice, the third brother Wei Tianji and the fifth brother Feng Yuheng did not think that it was the cat of the senior brother, but the second brother, the fourth brother, the sixth brother, the seventh brother and other four people thought that the senior brother was extremely suspicious, and the seven brothers had a fierce quarrel because of this, and the seven people who were originally like an iron plate became like a plate of loose sand.

In order to prove his innocence, Qin Tianshu silently wrote out all the contents of the cheats he remembered, and handed them over to the junior brothers, Zhong Tianxuan and the other six people also wrote a copy each, plus Feng Yuheng memorized the first seven mantras, and added the mantras to the seven heart dictations, and with mutual reference, the cheats are equivalent to being lost and regained, but the eighth and ninth chapters of the divine power, only the master brother has seen it, and he is silent about whether it is right or wrong, and it cannot be verified.

Once the rift arises, it can no longer be healed, and the differences and contradictions are getting bigger and bigger, the seven brothers do not trust each other and accuse each other, and there is no peace on the Yellow Mountain, which eventually leads to the eldest brother Qin Tianshu being upset and irritated and not practicing smoothly, vomiting blood and dying, the six brothers destroy each other for the death of the senior brother, and publicly abuse, the third senior brother and the fifth senior brother who are upright by nature are angry, and they go down the mountain angrily, vowing never to set foot on the Yellow Mountain again in their lifetime, and the Beidou faction has since embarked on the road of split.
