"This is also very simple, let's say that we have found a spirit grass, which can lead this pest to one place, and then concentrate on killing it. Fang Zhuo interjected when he heard this.

"Nonsense!" The old man in the green shirt turned pale and shouted, "You doll, talk nonsense." If people ask what Lingcao is, how should you answer?"

Fang Zhuo was glared at by the old man in the green shirt, and suddenly felt cold. He secretly slandered in his heart, and said in his heart that the old guys were so terrifying one by one, but he did not hesitate on his lips: "The seniors speak, and the juniors interject at will, but it is reckless." ”

The old man in black looked at him calmly, couldn't help but move in his heart, and hurriedly waved his hand and said, "No one blames you." Senior brother, this doll is the kid I told you about. ”

"Oh. The old man in the green shirt frowned.

The old man in black asked, "Fang Zhuo, listening to your words, it seems that the spirit grass you are talking about is not casually speaking. ”

Fang Zhuo bowed: "Senior, I do know that a spirit grass can attract this kind of pest, whether it is an adult or a larvae, to one place. But ............. ”

"But what?" the old man in black asked eagerly.

"This spirit grass is extremely rare, and it is basically impossible to find it. ”

"Tell me. ”

"The reason why I didn't say it before is because the probability of finding this spirit grass is almost zero. Fang Zhuo smiled slightly bitterly and spit out a name: "Dragon Artemisia." ”

"Tarragon?" the old man in black and the old man in green looked at each other, making sure he hadn't heard of the name.

"What kind of spirit grass is it, could it have another name?" asked the old man in black.

Fang Zhuo said: "I have seen the appearance of this spirit grass in that ancient book. However, it is recorded in the book that it is said that tarragon is actually a variant of the common mugwort. It is called tarragon because it is born where the bones of dragons are buried. ”

"Where are the dragon's bones?" the two old men were surprised.

"Exactly. Fang Zhuo said: "The corpse of the dragon contains a huge amount of aura and unique dragon qi, even if it is dead for tens of thousands of years, it is difficult to dissipate. When mugwort absorbs this aura and dragon energy, some changes will occur, and it will become tarragon. This spiritual herb is a treasure in medicine, and many Dan prescriptions need it. And this green-winged fly borer is the opposite of mosquitoes, preferring the smell of mugwort burning. But the temptation of ordinary mugwort to them is far from enough. If there is tarragon, just ignite it, and the green-winged flying borers within a radius of ten miles nearby will inevitably gather. Therefore, it is not impossible for the younger generation to say that they will be killed intensively. ”

The old man in black smiled bitterly when he heard this: "We can't use this method." However, it would be nice to use this as a shield afterwards. ”

The old man in the green shirt looked at Fang Zhuo and nodded slightly.

"In that case, let's set up a formation. The old man in green shirt commanded.

As soon as his voice fell, the six black-clothed disciples around him stepped forward in unison. The old man in the green shirt handed them three storage rings and waved his hand. The six black-clothed disciples rushed into the distance.

The old man in the green shirt was not idle, and threw out a twelve-sided array plate casually. His technique is far more skillful and clever than that of the old man in black, and the twelve-sided array has been lined up in the air, and after landing, it has been arranged into a formation.

Fang Zhuo was moved, figuring out the technique of the old man in the green shirt while watching the magic circle he had laid out. This formation Fang Zhuo is more familiar with, it is a shielding array. It's just that this shielding circle is a bit more complicated, and a small amount of banning is added to it.

Fang Zhuo looked at the outline, layout, and overall combination of this magic circle, and the more he looked at it, the tighter his brows became tighter. In his opinion, there are many flaws in this circle, which greatly reduces the effectiveness of the circle. And the biggest flaw was still in the spirit channeling part, according to Fang Zhuo's inference, the level of spirit consumption of this magic circle was higher, more than the additional cost of the teleportation circle just now. Fang Zhuo estimated that if he modified it in his own way, the loss of spirit stones in this magic circle could be reduced by at least forty percent!

He looked at the Spirit Guiding Array, and couldn't help but be taken aback when he looked at the part where the spirit stone was inlaid. Because this array plate can be inlaid with twelve spirit stones at a time. If this is calculated according to the middle-grade spirit stones, it can save almost five at a time! These twelve array disks are sixty!

Fang Zhuo didn't need to guess, the six black-clothed disciples should have taken the other three sets of shielding arrays. This total of four sets was combined to be able to completely envelop this huge spiritual field. This is still because the shielding array is relatively simple, the requirements are low, and the cost of spirit stones is also very low, otherwise this formation needs to be more large and complex.

This set of array disks saves sixty mid-rank spirit stones, and four sets are ............. Fang Zhuo's heart twitched fiercely, and his forehead dropped a big Luo Jin Immortal's head, this was two hundred and forty middle-grade spirit stones!

Fang Zhuo's eyes turned green immediately!

Two hundred and forty mid-rank spirit stones, equivalent to twenty-four thousand low-rank spirit stones!

Even if Fang Zhuo had made money easily before, and he didn't take spending money seriously, he was shocked by this huge amount of spirit stones. He looked at the array disk in front of him, as if he saw a large pile of shiny spirit stones beckoning to him. Fang Zhuo looked up at the old man in green shirts, feeling that if he gave up this opportunity, it would be equivalent to letting a boiled duck, no, it was a cooked dragon flying away!

"That, senior, can you discuss something?" Fang Zhuo really couldn't help it, and took a step forward and said.

"You say. The old man in black said.

"If these array disks are slightly modified, they can at least save forty percent of the spiritual power consumption. I............. ”

"Nonsense!" The black-clothed old man's face changed, and he shouted in a deep voice: "How can you understand this thing as a small Fu cultivator............?" ”

"Hirabayashi. The old man in the green shirt suddenly interrupted his words, squinted at Fang Zhuo and said, "You let him say it." I've been practicing for hundreds of years, don't we even dare to listen to the words of a junior boy?"

"It's ............. The old man in black glared at Fang Zhuo fiercely, and finally swallowed his words back.

Fang Zhuo was glared at by him, feeling cold and airy, passing through his body. He heard the old man in the green shirt say this, and he also knew that there was anger and disdain in his words. But at this time, it is already difficult to ride a tiger, and since you have spoken, you can say it in one breath.

"The kid was reckless. Fang Zhuo arched his hand, turned his heart sideways, and said: "Actually, the same is true of the teleportation circle just now, if you change the spiritual power transmission part, you can save at least thirty percent of the spirit stones." ”

"Oh?" the old man in the green shirt looked at him with a smile and said, "How to change it?"

"Senior brother, don't be like him. The old man in black persuaded.

At this moment, the teleportation array flashed, and an old man with white hair and a long hair shawl appeared in front of him.

"What's so hilarious?" asked the white-haired old man with a grin.
