Shi An nodded slightly, and asked Zheng Yan again: "There are a lot of demon beasts that eat the same food, will they be killed by mistake if they are trapped in the formation?"

Zheng Yan said: "I also thought of this, so if I am asked to set up this formation, I will add a formation flag that triggers the killing spell at the killing spell formation that is used, and if the demon beast trapped in the formation is not needed, I will stop the formation and drive it out, and if it is needed, the formation flag will be triggered for a spell attack." ”

"Well, I would do the same if I had done it. So, can the other two formations be adjusted like this?" Shi An nodded again, and threw out another question to see the answers of the three of them.

Zheng Yan tilted her head and thought for a while, and said: "I'm afraid it won't work, the 'trap formation' can also use food as bait to trap, but there is no place to set up a formation flag, the only culling spell is the earth spear technique, if it is removed, it is no different from the trap of ordinary mortals, and it is impossible to achieve the purpose of culling demon beasts, but with the earth spear technique, there will be the possibility of accidental killing." As for the 'Ten Sides Ambush Formation', there is not even a place to put food, let alone selective hunting, and I can't think of any ideas that can be modified for these formations. ”

Chen Qi and Tang Zhi looked at each other without making a sound, and it seemed that they couldn't think of a better way than Zheng Yan.

For Shi An, solving these problems is the easiest at all, and the three formations are improved to achieve the best results, and he can come up with four or five solutions in an instant. This is not to say that he needs to use intermediate and high-level formations to achieve it, it's just that these three disciples still haven't departed from the inherent formation routines, and have not adapted the use of formations to the situation, or rather, what they lack is not knowledge and skills, but practice and experience.

"Well, judging from the formation design ideas of the three of you, Chen Qi is thinking about efficiency, Tang Zhi is thinking about efficiency, and Zheng Yan is thinking about effect, all of them make sense, and they also have their own advantages in actual use. However, if I were to design it, it would be exactly the same as Zhengyan's," Shi An stopped smiling and said seriously: "Setting up a formation is the same as being a person, this is also one of my experiences over the years, and I will take this opportunity to teach you one last lesson today." ”

After a pause, he continued: "Your Yuan Miao Master Ancestor has talked to me many times about the Dao heart of a cultivator, and this is also a question that I have been thinking about for a long time, what is my Dao heart? When I was young, I fantasized most about becoming a chivalrous man, fighting the sword in the world, helping the weak and the poor, and doing the Tao for heaven was my ideal at that time. But unfortunately, I never had the opportunity to practice martial arts, and this dream came to naught. After learning mortal medicine from the master who raised me, I began to fantasize about becoming a good doctor who can help the world, and it became my dream at this time to save people in times of danger and help people in fire and water, and I have been working hard for this purpose. But the creation made people, and later my master's family was killed by traitors, and the soul returned to the world, so I had to embark on the path of cultivating immortals......"

Shi An will omit all kinds of encounters in the mortal world, the life of a monk who began after meeting Yuan Miaozi, the stories in Kaiyuan City and Zijun Mountain, the story of the Twin Towers City and the return to the Four Elephants, and all kinds of hidden things, after all, there must be spies sent by Yuan Daozi among these people, and too many details will reveal all kinds of inexplicable mistakes.

"I don't like to kill and try to avoid it, but that doesn't mean I'm a good person. All living beings have the right to live, and it is also a rule of heaven that the law of the jungle eats the weak, but killing is also limited to the purpose of self-survival. Therefore, it is absolutely unconscionable to kill innocents indiscriminately, or to kill for pleasure. My hands were also stained with blood, Jin Huan died at my hands because no one punished the murderer, and killed Jiaojiao and the bandit leader in Zijun Mountain, not only because they wanted to kill me, but more importantly, they were also unpunished. Murderous villains, many monsters in the mountains were killed by me because I needed food for survival, I didn't kill the Flame Eagle, it attacked me and it acted on instinct, which is understandable, and the only thing I was ashamed of was a monster that I killed but didn't eat, and all I could do was bury its corpse. Other than that, to this day, I can say that I have not done anything that is contrary to the gods and spirits. So I'm thinking, my Dao heart should be in accordance with the principles of heaven. ”

After saying that, the three disciples all froze in place, and no one said a word.

After a while, Chen Qicai said, "Thank you, Mr. Yizhi." I also think that Zhengyan's design is better. Then he got up and left.

Tang Zhi didn't say anything, bowed deeply to Shi An and left the hut.

Seeing that the two had left, Zheng Yan asked softly, "Brother Shi, is what you just told us true?"

Hearing her ask, Shi An was stunned for a moment, then lowered his head and sighed softly: "Alas, this is my past." The story of me and Uncle Yuan Miao, which I didn't tell you before, was unconsciously told today, but that's okay, I finally told the words that had been held in my heart for so many years. So...... So I want to thank you all as well. ”

"Compared to you, I am much happier, there are elders in the family who love me, and there are ...... in the sect who have always taken care of me Yuan Miao Shizu", speaking of which, Zheng Yan really wanted to run out of the house immediately, Mr. Yizhi told his story with his heart, and he had to deceive him, and he couldn't help but feel a little ashamed. "Brother Shi, you not only taught us the knowledge of formations, but also taught us how to behave and cultivate, but I, alas, ...... I'm sorry. ”

Hearing her say sorry words, Shi An was a little stunned, and when he looked up and was about to ask, he noticed that Zheng Yan's eyes were red, obviously crying not long ago.

"Zhengyan, did you cry just now? What's wrong?"

"I feel sorry for ......" Leng Buding was asked by Shi An, and Zheng Yan blurted out. As soon as the words came out, he immediately thought of something, and his little face turned red and he ran out of the hut.

"Distressed......" Shi An was also stunned.

......

Zheng Yan trotted all the way back to the cave, and the red tide on her face never subsided.

After the gasp calmed down, he slapped himself lightly and said softly: "Wei Yan, Wei Yan, what kind of ecstasy did you take, why did you feel distressed when he told a story?"

I couldn't help complaining about Mr. Yizhi in my heart: Brother Shi, how can you have such a clever mouth, you can talk about your experience so thrilling, and you can talk about your experience so distressing? She wept when she heard that Zhao Langzhong had arranged for his family to be killed after he left for an excuse to save his life, and she shed tears when she felt this strong family affection; she wept when she heard that he was forced to jump off a cliff and stubbornly supported him, and felt this pain and that firmness; she shed tears when she heard that Zhao Langzhong and his wife were crushed and scattered, but he could not cut all these evils, and felt his pain that could not be resolved but had nowhere to be released; she shed tears when she heard that Yuan Miaozi left him in Kaiyuan City and was alone in danger, and she felt the loneliness and helplessness; Qing Guzi framed him as the culprit of stealing the sword, but he could not refute it, and she shed tears when she realized the grievanceAnd obviously the sect is in front of you but can't return, the teacher is in front of you but can't fulfill her filial piety, she felt that melancholy, that trace of affection, she shed tears.

When the image of a wise and brave, affectionate and righteous man gradually became clear, and the image of Ruyi Langjun in her heart slowly coincided, the waves in the little girl's heart gradually rose, and the flush that had just retreated slowly covered her delicate cheeks.
