More than eight months have passed in the blink of an eye, and Shi An has not had any more individual contact with the three disciples.

Most of the contents of the first ten volumes of the "Formation Essentials" had already been taught to them, and Shi An had practiced them in Kaiyuan City and Twin Tower City, and understood that this was slightly higher than the level of the primary formation, and it was fully capable of meeting the requirements of the vast majority of the patrons of the Summoning Kingdom.

As for the more than 20 volumes in the back, because it involves deeper content, there are a lot of intermediate and high-level formations in the middle that have great effects but are not commonly used, he doesn't want to teach them, firstly, it violates his mother's admonition to himself, and secondly, it is enough to teach to this extent that he is worthy of the Four Elephants, and thirdly, he doesn't want to show his excessively high level of formations, and he still understands the truth of "Pifu is not guilty, but he is guilty".

After the end of the day's teaching, Shi An preached to the three of them: "So far, I have finished teaching all the formation content that you should learn, and I will go back to teach the sect master, and tomorrow the Four Elephants Temple will be able to accept all kinds of formation business." In the future, I will also start my cultivation in retreat for a period of time, and if there is nothing else, there is no need to disturb me. ”

When the three of them heard this, they were mixed with joy and sorrow, they were happy that they could finally become a teacher, and a sense of accomplishment arose spontaneously; they were worried that they did not have any practice of arranging formations, and they had no confidence in whether they could really complete it independently.

Shi An looked at the expressions of the three of them and said with a smile: "I know that you don't have a plan in your mind about whether you can arrange the formation independently, it doesn't matter, the first three of you will complete the first three businesses of the Four Elephant Vision, and the three of you will complete the layout design according to the requirements of the customer, and then show it to me, and I will personally modify it for you." After three transactions, you can complete each other. My suggestion is that you still have to design and implement the first few formations together, you must know that it is difficult to create a good name, and you need continuous success to accumulate reputation, and to make a bad name, you only need to fail once. Therefore, when you are inexperienced, you should negotiate more and achieve success with the greatest certainty. ”

Shi An paused for a moment, and then said: "What I teach you is only the principle of the formation and the general model, but the requirements of the patrons are varied, I hope you will think more, deduce more, and finally do it." The improvement of the formation level is not in the mind, but more in practice. Finally, I would like to say that if anyone asks who gave you the formation, it is best not to mention my name, but only to say that it is transmitted from the Four Phenomena Temple. ”

Chen Qi rolled his eyes and asked, "Sir, are you afraid that we will damage your reputation?"

Shi An glanced at him with some disgust, and then smiled at the other two and said, "It's not, it's still what I said before, I taught you the formation just a deal with the sect master, so we saw that it was not a master-apprentice relationship." If you still know me as a person in the future, I will be happy, but if you forget it in the blink of an eye, it doesn't matter. This trading period is five years, and I can be responsible for solving all your problems in the formation for five years, and after five years, I will not be obligated to take care of you anymore. ”

When the three of them heard this, they were speechless.

In the next few days, the Four Elephants Temple set up a formation hall, and the hall master was naturally the only Zheng Yan who had the identity of an inner disciple, and she was also specially arranged for a single cave house, responsible for the reception of patrons and the management of the income of the spirit stone, Chen Qi and Tang Zhi also arranged their own accommodation in the dormitory of the formation hall, so that they no longer had to live in the miscellaneous courtyard with a lack of spiritual energy like those outer disciples.

The newly opened formation hall recruited many outer disciples, with Chen Qi, who could speak well, as the instructor to give an introductory explanation, and Tang Zhi was mainly responsible for the design and implementation of the formation. At this time, there were no patrons outside the sect, but many inner disciples from the foundation building period came to ask for the formation.

The first business was that their Uncle Yunfan wanted to set up a formation to protect the cave mansion, although there was no difficulty for the three of them, but after all, it had just opened, and the three of them got together to come up with their own designs, and after learning from each other's strengths and weaknesses, the design was perfected, and then showed it to Shi An.

"Yes, the overall idea is correct, there is nothing wrong with the formation diagram, formation symbols, etc., you can use it to implement, just strictly abide by the four steps I said. Shi An affirmed this design, and the three of them went happily.

The success of this formation greatly attracted the enthusiasm of the disciples of the sect, and they came to the formation hall to buy all kinds of formations. More than two months have passed, and the Formation Hall has begun to have a business of foreign customers, seeing that there is continuous income from spirit stones, Yuan Daozi is also quite pleased, although the current income is not large, but it is better than nothing. There is another point that he is even more overjoyed, among the three of them, although Zheng Yan is not as flexible as Chen Qi, and not as solid and steady as Tang Zhi, but if you want to talk about the speed of carving and arranging the formation, it is none other than her who has the lowest cultivation, Yuan Daozi did not have the expectation that Zheng Yan could learn the formation well, but inadvertently realized it.

But there was a business in which the three of them had a different opinion, and went to the cabin noisily.

In the past two months, because he no longer had to get up early to teach, Shi An's time outside the Cave Heaven Stone had been fixed at the time when it was close to noon to the time when it was close to night, and the rest of the time he spent cultivating in the Cave Heaven Stone. During this period of time, the cultivation was still mainly infused with aura, and occasionally looked at the "Continuation of the Formation Tips", while the four sub-souls and sixty-four divine senses were placed in the futon for a long time to nourish.

Seeing that the three of them had different opinions on the arrangement of the formation, Shi An asked them to explain themselves.

Zheng Yan couldn't hold her breath, so she preemptively said: "Mr. Yizhi, that's the case, there is a patron who is going to go to the southern vein of Zijun Mountain to catch the second-level demon beast, and hopes that we will set up a large hunting formation for him, Senior Brother Chen Qi advocates using the 'Trap Formation', Senior Brother Tang Zhi advocates using the 'Ten Sides Ambush Formation', and I advocate using an ordinary 'Hunting Beast Formation', the opinions are not unanimous, and no one can convince anyone, so I came to you to make a decision for us." ”

When Shi An heard this, he said to the three people: "Then you should each tell your own reasons." ”

Chen Qi's eyes rolled and said: "I advocate using the 'Trap Formation' based on the actual situation of the client, he is a loose cultivator in the late stage of foundation building, and the purpose of hunting is to obtain all kinds of demon beast materials in exchange for spirit stones, and then buy various auxiliary pills for the advanced pill stage." He doesn't have much property, and he doesn't have much other income, so I recommend using the 'Trap Array', the spirit stones invested are much less than the other two formations, especially the 'Ten Sides Ambush Array', although the prey harvested is not as good as the 'Ten Sides Ambush Array', but it is more than the 'Hunting Beast Formation', according to the ratio of pay and harvest, the 'Trap Array' is the highest, so I suggest this. ”

Shi An nodded and said, "There is some truth to that. What do you think, Tang Zhi?"

Tang Zhi hesitated for a moment, and then said slowly: "I suggest using the 'Ten Sides Ambush Array' because of its powerful function, not only has a wide coverage, but the main reason is that there are absolutely no fish that have slipped through the net after the demon beasts enter the formation, and the culling efficiency is higher, and there is another reason that the conditions of this formation are relatively harsh, and the deployment of this formation can better show the level of our Four Elephant Viewing Formation Hall formation, which is a good opportunity for 'a burst of fame'." ”

Shi An was noncommittal, turned his head to look at Zheng Yan and asked, "Then tell me why you advocate using the 'Beast Hunting Formation'?"

Zheng Yan blinked her eyes wide and replied, "My thoughts are different from them, and the 'Ten Sides Ambush Formation' is something I firmly oppose. I remember that when you taught us about formations, you said that formations should only be used as an auxiliary means for monks, and should not be used as the only means of killing, and even if they do, they should be as open as possible. The scope of the 'Ten Sides Ambush Array' is extremely wide, and the lethality is too strong, and none of the second-level and below demon beasts that enter here survive, which is too cruel. The second-level demon beasts that the customer wants are only a few few, but this formation can't identify the category of demon beasts, and using it is definitely indiscriminate killing of innocents, so I don't recommend using it. As for the 'trap formation', as Chen Qi said, it is indeed the most cost-effective one, but the problem is that there is also the possibility of killing other demon beasts by mistake. The 'Beast Hunting Formation' is much better, you can place the food you need for the demon beast on the formation that triggers the formation, so that all the demon beasts that feed on it will be trapped in the formation, I think this is the best design. ”
