Under Han Li's gaze, the flying knife slashed at the stone wall, bursting out with a dazzling white glow.

Lu Weiying's face changed slightly, and with a gesture of reaching out, he immediately took the flying knife back.

Han Li fixed his gaze and saw that where the flying knife hit, a shallow knife mark with a depth of an inch appeared, and there were faint grains of silver light faintly shining out from the knife mark.

"This is ......" The old man's face flashed with surprise, and he hurriedly stepped forward a few steps, walked to the place where the knife was marked, and observed it carefully.

"Gangyinsha, there is a Gangyinsha original mine in this stone wall?" the old man only observed for a while, and then his voice trembled slightly.

As soon as he heard the words "Gang Yinsha", Han Li's expression changed drastically. He also stepped forward, stretched out a finger, and stroked the knife mark lightly. Carefully identified,

"Gang Yinsha is a material, Han Li has naturally heard of it. Because it is one of several materials that can be added to the refining weapon to make the magic weapon stronger. In terms of effect, it is a rare material second only to crystal refining.

This material itself is also extremely hard, and the magic weapon is difficult to urge, whether it is the Chaotic Star Sea or the Tiannan Immortal Cultivation Realm, it is a kind of near-extinction existence.

No wonder Lu Weiying's flying knife slashed up, almost without any effect.

Han Li looked at the scar marks solemnly for a moment, and then suddenly raised his hand silently, and more than ten small swords with blue light flew out from his sleeve robe, turning into more than ten green rays and shooting straight at the entire stone wall.

The two of them were stunned at first, but they immediately understood Han Li's intentions.

I only heard a clanging noise. More than a dozen sword holes several inches deep appeared on the stone wall. There were also specks of silver light shining out of each sword hole.

"The ground is indeed Gangyinsha, and it is good. And the entire stone wall is mixed with Gangyin sand. But the density is not uniform. It doesn't seem to be man-made. Rather, the stone wall itself contains a vein of silver sand. Han Li had a look of surprise on his face. The voice said unhurriedly.

When he saw that Han Li's flying sword was able to stab a sword hole on the stone wall that was several times deeper than his flying sword. Nan Longhou's faces changed slightly.

But after hearing this, the old man surnamed Lu. The look of greed in his eyes brightened. Staring at the stone wall. Say no more.

There was also a hint of fiery color flashing on Nan Longhou's face. But think about it. His expression gradually returned to normal.

Let's go. Let's go to the inner valley to explore the treasure first. Nan Longhou said calmly.

"Let's go? These Gangyinsha are rare treasures. We might as well knock some down first. The old man hesitated for a moment, and said with a reluctant face.

"Brother Lu, why are you confused at this time! How hard these Gangyin sand are, haven't you seen it yourself just now? Don't look at the Gangyin sand ore that may have an entire vein here. But a piece of raw ore the size of a fist can only be refined into a little bit of silver sand the size of a grain of rice. How long it will take you and how much mana you will consume to cut enough ore. Besides, this thing is precious, but don't forget that what we lack now is not these things outside the body, but elixirs that can prolong longevity and quickly improve the realm. Otherwise, when the limit comes, we will be just a pile of bones. Nan Longhou frowned, glanced at the old man, and said meaningfully.

Lu Weiying heard Nan Longhou say this. was stunned for a moment, and then nodded again and again.

"What Brother Nanlong said is very true! The old man was so blinded by the treasure for a while that he almost forgot the main purpose of this trip. Thank you, Brother Nanlong, for reminding me. "The old man is not an ordinary monk, after being reminded by Nan Longhou, he immediately came to his senses, and Chong Nan Longhou clenched his fists with a trace of gratitude. Said.

Then he stopped looking at the stone wall, and walked quickly to the cave for fear of being tempted again.

The look on Nan Longhou's face eased at this time, and he greeted Han Li and walked in as well.

Han Li was also very reluctant to give up on the Gangyin Sand of this entire vein, and his pace couldn't help but slow down a little.

However, even if his flying sword was mixed with Gengjin, it was far sharper than an ordinary flying sword. There is also an ichor that can restore mana instantly. It is also not an easy task to cut enough Gangyinsha ore. On the contrary, it is likely to provoke the jealousy of the two Nanlong Marquis.

Thinking about it, it was really hard to start, and Han Li could only sigh lightly. Those with a sense of regret will follow the two into the cave.

But at this moment, Han Li's mind suddenly sounded with the voice of the Great Yan Divine Monarch: "Hehe, there are so many Gang Silver Sands. The old man searched for a long time, but he didn't find much land. They can be used on the puppets newly developed by the old man, and the puppet bodies mixed with these silver sands are just right. Ordinary treasures can't hurt them in the slightest. Let's get rid of all this silver sand. Dayan Divine Monarch's voice was full of excitement.

"Get them all away??old monster, you didn't wake up, did you? This is the Gangyin sand vein, not the spirit stone vein. How can I get it all away and cut it piece by piece with a flying sword?" Han Li replied angrily as soon as he heard this.

"Hmph! Since you said so, of course there is a way. Han Boy. Isn't there a lot of gold-devouring insects? I call you a magic decision, which can manipulate the gold-devouring insects to burrow into the stone wall and devour the Gangyinsha, and then spit it out and condense into Gangyinsha crystals. This method was obtained from a killed insect cultivator in the past. Not only the Gold Devouring Worm, but also several other spirit worms can do this, but it is not as convenient as your Gold Devouring Worm. Dayan Divine Monarch had already said preparedly.

"There's such a mantra, okay, let's teach it. I'll immediately let these spirit worms collect the Gang Silver Sand. Han Li was surprised and delighted when he heard this, and immediately spoke. I don't know if it's for Gangyinsha or for the power formula.

"I'll tell you first, no matter how much Gang Silver Sand you get, you must leave it to me to refine the last puppet first. It must not be wasted elsewhere, let alone mixed into your magic weapon. If you refine the puppet, there will be a surplus in the end. You'll take care of the rest, and I won't take care of it. Before passing it to Han Fa for decision, Dayan Shenjun indifferently said his conditions.

"The seniors don't seem to know that there is no need to mix the magic weapon with Gangyin Sand at all, and they have already been trained with crystal refining. That kind of material can be better than Gangyinsha, and the effect is better. Hearing this, Han Li couldn't help but chuckle.

"Crystal refining? You still have this kind of anti-heaven material. There's nothing left, and as long as there's a little bit left, I'll be of great use. Dayan Shenjun seemed to be stunned for a moment at first, but immediately shouted excitedly, his voice full of ecstasy.

"As you know, the magic weapon I use is a whole set of flying swords. Although the refining crystals obtained at the beginning were not small, they were only barely enough, so what was left. Han Li replied lightly.

"No, what a tyrannical thing!" "Dayan Divine Monarch suddenly became extremely disappointed, and his mouth was full of muttering regret.

Hearing this, Han Li couldn't help but roll his eyes a few times.

Using refining crystals on the natal magic weapon, how can it be regarded as a tyrannical celestial thing. However, he now has a request from the other party, and he can only pretend not to know and listen to a few complaints from the other party.

At this time, Han Li had already followed the two people in front of him into the cave for a certain distance, and intentionally or unintentionally deliberately opened a certain distance. lest the two of them show his strange appearance.

This cave is a little dark, but all three of them are people with advanced mana, as long as they inject a little spiritual power into their eyes, they can see clearly, and there is no problem with vision.

The size of the cave is always the same at the entrance of the cave. The two-color stone wall is still the same pale yellow color.

On the way, Han Li casually used another flying sword to slash through the stone wall.

As a result, it was still a silver glittering color. Han Li was a little shocked. But the thought of occupying these veins in the heart is two points better.

As Han Li walked, he listened to a worm repellent mantra that Dayan Divine Monarch had passed on to his Divine Sense.

Although the formulas are all composed of ancient texts, they are somewhat obscure. However, under the few words of guidance from the Great Yan Divine Monarch, Han Li, who had already had a little experience in insect repellent techniques, suddenly became enlightened and smoothly comprehended.

As soon as the mantra was taught, the voice of the Great Yan Divine Monarch fell silent again.

Han Li lowered his head and pondered the mantra again, after confirming that he was at a loss. With a seemingly casual flick of one hand on his waist, a spirit beast bag suddenly disappeared.

Afterwards, Han Li's walking posture did not change in the slightest. But from the sleeve robe, one by one the golden gold-devouring insects flew out silently, quietly flying towards the road they came.

The two of them who were walking in front of them for more than ten zhang were not aware of Han Li's little hands and feet at all.

After walking a cup of tea, all the gold-eating insects in the bag were released.

Han Li's hands shrunk into his sleeves and formed a magic seal, and his divine sense resounded with a muffled incantation. And through his divine sense, he returned to the entrance of the cave and was floating in front of the stone wall on the body of a large group of gold-devouring insects.

The golden insect cloud suddenly burst into golden light, and then all the flying insects blurred for a while, and then rushed towards the stone wall, but they escaped directly into the stone wall without the slightest hindrance, and disappeared without a trace.

The stone wall looks like it is not damaged in the slightest.

Han Li sensed this situation with his divine sense, and only then did he retract his mind with peace of mind and take a slight step.

After walking for a while, just after turning a corner, the two people in front of them stopped. Han Li's heart sank, and he hurriedly looked forward.

I saw that the front suddenly opened up, and the passage suddenly became a little wider.

In this wide passage, stalactite-like strange stones are scattered from top to bottom, and a silky silver-white light is emitted, illuminating the entire passage with extreme light.

These silver filaments are strange and abnormal, although they are obviously intangible, but each filament of light is clear and abnormal, as if it were tangible.

"This is Baiji Yuanguang. Although the two Taoist friends should know something, they have to remind them again. In the Northern Elemental Light, except for the Liangyi Ring, you must not use any spiritual power and magic weapons. Once the spiritual power leaked from the body, it was sensed by the Northern Element Light. The three of us are absolutely dead. Nan Longhou looked at the silver thread in front of him, took a deep breath, and said solemnly. Han Li was silent and did not answer this. But with a shake of the robe, a jet-black ring flew out, and one hovered and fell into the palm of his hand. It's flashing on it!
