My talisman pen is omnipotent. How should you deal with it?

After hearing Chu Ci's words, Fang Cheng's eyes flashed with solemnity. He calmed down and then slowly spoke:

"I really don't know anything about the origins of those people. As for why they arrested me and interrogated me..."

Having said this, Fang Cheng paused, lowered his head and thought for a while before continuing:

"They might be here for a battle formation diagram."

Chu Ci frowned when he heard this. Formation diagram? Could this be related to Fang Yuan? He guessed secretly in his heart.

Seeing Chu Ci's reaction, Fang Cheng seemed to realize something. He added: "In fact, I have lost this battle formation map a long time ago, but those people didn't want to believe it, so they tortured me to extract a confession."

Although Fang Cheng said it lightly, Chu Ci could still feel his wariness towards him.

"Array diagram? Could it be that it was left behind by Daoist Fellow Fang Yuan?"

When Fang Cheng heard the word "square and circle", his eyes lit up. He asked eagerly, "Do you know my nephew?"

Chu Ci smiled and said, "It seems that Fellow Daoist Fang has indeed forgotten me."

Hearing this, Fang Cheng's eyes widened and he stared at Chu Ci intently, as if he was lost in his memories, trying to find some clues from the other's face.

After a long time, Fang Cheng shook his head helplessly and showed a bitter smile: "Sorry, sorry, I really can't remember when I met you."

Chu Ci was wearing a disguise talisman, so Fang Cheng naturally couldn't recognize him.

"Fellow Daoist Fang, don't worry about it. In fact, this happened a long time ago. I went to your store more than ten years ago, and I met you two once. I also gave him a talisman that can change his appearance."

Hearing the word "disguise", Fang Cheng's eyes instantly brightened. He slapped his forehead and said in a lost voice: "I remember now! It turned out to be you, but you should still be wearing a disguise charm."

Chu Ci smiled, and suddenly remembered that he was seen through by the other party in Fang's shop before. He stretched out his hand and gently wiped it, and the bearded man's disguise talisman disappeared instantly, revealing his original appearance.

"There is no formation to help me here, so I guess you can't see my true face."

When Fang Cheng saw Chu Ci's true face, he finally remembered who the other person was. He looked at Chu Ci deeply and said, "I haven't seen you for ten years. I didn't expect that I would be saved by you today." His voice was full of emotion and gratitude.

Chu Ci waved his hand and said, "Fang Daoist, you don't have to be polite. I came here to look for Fang Daoist. I just happened to come across this incident, so I can't just stand by and watch."

Fang Cheng nodded after hearing this and said with a sigh: "Ten years have passed in a flash, and your cultivation has improved so much. I am really ashamed of myself."

At this point, Fang Cheng suddenly remembered something and asked, "By the way, I still don't know what to call my friend?"

Chu Ci smiled slightly and replied, "I am Chu Ci."

After he finished speaking, he looked around. The square-faced man and the silver corpse were nowhere to be seen. He didn't know where they had gone. Would they cause any more trouble? It would be better for him to leave first.

Thinking of this, Chu Ci continued, "I think this is not the place to talk. In my opinion, we should leave first and find a safe place."

Fang Cheng nodded, but then he looked embarrassed:

"Those two bugs just now sucked too much of my blood and essence. Now I can't even walk, let alone fly."

Seeing this, Chu Ci knew that Fang Cheng was seriously injured. Although he had used the rejuvenation charm and Qi and blood pills, it would take some time for him to fully recover.

After a brief thought, Chu Ci summoned a green flying sword. This flying sword was a trophy obtained after the battle at Wulong Village.

Flying with a sword wastes more spiritual energy than flying alone, so Chu Ci has never used it, but it is just right to use it to carry people at this moment.

"Fellow Daoist Fang, please draw your sword." Chu Ci gestured with his hand.

Fang Cheng nodded gratefully and stepped onto the flying sword. Chu Ci then jumped onto the flying sword as well, and the two stood side by side, flying on their swords.

Half an hour later, the two flew into a dense forest. Chu Ci asked Fang Yuan about his situation on the way.

From Fang Cheng, we learned that Fang Yuan had left Lingxi City many years ago and went to a large sect in the Qin Empire to study, specializing in the art of formations.

On the way, Chu Ci explained to Fang Cheng his purpose, that he wanted to buy some battle flags and that he wanted to find a way to crack the blue circle battle formation. Fang Cheng immediately said that although his nephew was not there, he could also try to study it.

After entering the woods, Chu Ci handed a jade slip to Fang Cheng. Fang Cheng sat cross-legged on the ground and began to study with his eyes closed.

Logically speaking, his injuries were serious and it was not appropriate for him to use his spiritual power. Chu Ci originally planned to let him rest for a while, but finally, under Fang Cheng's insistence, he had to start immediately.

Fang Cheng sat on the ground holding the jade slip, his brows sometimes furrowed and sometimes relaxed.

Nearly two hours later, Fang Cheng slowly opened his eyes: "Fellow Daoist, this formation is indeed mysterious. In my opinion, it will take at least six Jindan cultivators working together from six directions to break it."

Chu Ci nodded after hearing this. His attainments in the field of equation formations were indeed quite profound. It took him two days to figure out the method to crack it, but the other party had completely understood it in less than two hours.

Fang Cheng spoke again: "I think this method is very difficult for Fellow Daoist Chu. If Fang Yuan were here, he might be able to come up with a more ingenious way to crack it." After saying that, he sighed.

It seems that Fang Cheng has indeed tried his best. A trace of disappointment flashed in Chu Ci's eyes, and he asked:

"In that case, what are your plans for the next step? Do you still have those battle flags? If it's convenient, I plan to buy some just in case."

Since the other party doesn't have any good solution, I have no choice but to give up.

Fang Cheng pondered for a moment after hearing this, and then slowly said, "After getting into trouble with those unidentified villains, I'm afraid it will be difficult for me to continue running this store. I plan to go back to my hometown so that Fang Yuan can find me when he comes back. As for the formation flags in the store, since Fellow Daoist Chu wants them, I will give them all to you."

Chu Ci quickly shook his head and refused: "Fang Daoyou, I appreciate your kindness. But I can't take these formation flags for nothing. I can't give you any less spiritual stones. Otherwise, I don't want the formation flags."

The two of them declined again and finally decided to return to the store first.

The shop was filled with a wide variety of battle flags, totaling more than a thousand. Chu Ci remembered that when he bought these battle flags, each one cost about 200 spirit stones. He quickly calculated and then put down spirit stones.

Seeing this, Fang Cheng no longer insisted. He accepted the spirit stone and said, "Since you are so generous, I also have something to give you to express my gratitude."
