Seven Kills Sword Technique, Seven Kills Seven Styles, Cold Wind Reaches the First Realm of Seven Kills Sword Technique, a good start.

He walked out of the peach blossom backyard, walked around the Nine Heavens Xuan Palace, and just met Su Jinglu's ninth uncle, exchanged a few words, and inquired by the way, where Su Jinglu was.

Under the guidance of Uncle Jiu, he walked along a ravine in the backyard in the direction of the rising sun, looking for Su Jinglu's traces.

A narrow ravine, the bottom of which is full of pebbles, and the sides are covered with lush artemisia grass more than a foot high.

Large and small, colorful pebbles, with a thick layer of fine sand underneath, freshly washed by the rain that flowed down from the mountains, clean and spotless.

It's a narrow valley terrain, and the sun only shines in at noon.

The tall and fluffy artemisia grass was covered with sparkling dewdrops. The cold wind didn't go far, and the clothes on his body were wet, and the wet fabric was clinging to the skin, slippery and greasy.

The canyon is dim and dark, with no end in sight, and when you look up, you can see cliffs on both sides.

The angular rocks, large and small, are clearly visible and the fractured gaps are clearly visible, giving people a crumbling feeling.

Wow!

At this moment, he heard the sound of a mountain spring rushing and immediately quickened his pace.

Listening to Uncle Jiu, the place where Su Jinglu went was close to the pass of a waterfall.

Pushing aside the grass and seeing the peach source, he finally walked out of the dense weeds and looked up: "Oh my God, what a big waterfall!"

I saw a huge mine pit, on the surrounding cliffs, ancient trees towering to the sky, huge rocks stood steeply, waterfalls were overhanging, flying straight down, and the momentum was extraordinary.

Surrounded by verdant green, surrounded by mountains, strange rocks, strange peaks inserted into the sky, a majestic and magnificent scenery.

In the distance is a dense wooded area, and the waterfall in the forest rushes down from the cliff, shining silver and mist, and falls into the pool below the cliff.

At the bottom of the pit, the water of eight waterfalls converges to form a huge pool, and a striking whirlpool is located in the middle of the pool, which is surrounded by mountains, and the water in the pool does not flow out.

At the bottom of the deep pool, connected to the dark river, a funnel-shaped whirlpool is formed.

"Xiao Su!"

I saw a familiar little man, standing on the edge of the pool, the cold wind triggered the true power of the earth, stretched his arms, and jumped down.

Control the rhythm of the fall, glide in the air like a bird, and landed firmly behind Su Jinglu.

This pool of clear water in front of you, the shadow of thousands of mountains and thousands of peaks is reflected in the water, the lake and the mountains are beautiful, and they are reflected into brilliance; in the southeast, south, northwest, and northwest, eight waterfalls that flow straight down, like the dragon drinking water, gush out, the drop is 100 meters, the waves splash, and the roar is deafening.

"Brother Feng, are you here too?" Xiao Su looked back at him and smiled happily.

He watched carefully at his feet, the stones here were round and bare, and covered with green moss and ferns, so slippery and slippery that he might slip and fall into the water if he was not careful.

"I came to see you, I heard that you were collecting some special materials, so I came here to take a look. ”

Hanfeng and Xiao Su stood together, stepping on a large rock.

Su Jinglu was pleased, and smiled: "A mineral called squirt, this pit has been abandoned for a long time, I just came to try my luck, and I may not be able to find it." You're so calm and idle, and you've come here to find me. Isn't it, you have made a breakthrough in the artistic conception of the Seven Killings Sword Technique......"

"Exactly!"

He grinned, looked relaxed and confident, and patted Xiao Su on the shoulder.

"It's amazing, I broke through so quickly, I deserved to come out of a cold door, and my own martial arts came easily. Xiao Su bared his teeth and was happy in his heart.

"It's just luck!"

The law of the wind system, among the nine laws, is not very complicated, and the first realm and the second realm of the Seven Kills Sword Technique are only the beginning of the Seven Kills Sword Technique. There is still some element of luck in mastering the first realm so quickly.

Xiao Su smiled, frowned, and said with emotion: "Your luck is so good, I don't know how lucky I am today-"

"Look at you standing here for a long time, what are you doing, aren't you here to mine stones, why don't you pick up a stone?" he asked puzzled, looking at the pool of clear water.

"Get off the net!"

At first glance, he didn't understand, and he smiled bitterly: "What, are you laying a net, is it mining or fishing?"

Eight waterfalls converge, at the bottom of the pit, forming a deep pool of rippling blue waves, the pines and cypresses hanging around the pit, the dragon hanging on the wall, the branches and leaves, how to say that it has grown for more than a thousand years, there will naturally be fish in the pool to breed here.

"Mining with nets, this net, I've been here for almost three years, and it's time to close the net. Xiao Su's hand was across his forehead, and it was close to noon, and the sun was a little dazzling.

Listening to this was a little confused, he frowned slightly, and asked: "What kind of 'fish' are you trying to catch, is it difficult to catch, a net has been under the water for three years, it is estimated that it has already been broken——"

Xiao Su was staring at the bottomless, rippling pool, and smiled back: "Brother Feng, what I caught is not an ordinary 'fish', and my net is not an ordinary net ......"

Unusual nets - novelty!

"Then you might as well close the net and see—" The cold wind waited a little impatiently, he had never heard of it, and there were also those who mined in the water.

Su Jinglu explained: "I used the five elements to lay a dense net here, and some fish and ordinary sand and stones can pass through. However, there is a type of ore debris called '碜' that sticks to the net. ”

Granite is a rare mineral in nature, there will be a small amount of mineral deposits in the deep mountain veins, and the reserves are also small and pitiful, and it is not easy to mine. Stone is generally used in the forging of steel, which can greatly improve the toughness and yield point of steel.

"So the ore you're looking for is a stone—" Cold Wind suddenly realized.

"Brother Feng, do you know that this pit we are in used to be the largest stone mine in the Eastern Continent. Now, there is no complete rough stone to be found here. ”

Xiao Su shook his head, very helpless.

Stone can improve the toughness and yield point of steel, and it has become a necessity for casting high-quality weapons.

There are very few reserves of granite in nature, and this huge pit was also a huge 100-ton mine in the past. Even though the reserves are huge, they cannot withstand tens of millions of years of reclamation, and have been exhausted and completely abandoned.

Han Feng nodded, looked around at the empty and barren four walls, and smiled bitterly: "It's hard for you, I actually thought of using a net to filter slag, this local method." ”

"Collect the net!"

Su Jinglu waved his small hand, and a layer of ripples rippled on the clear water surface, as if it was drizzling, and I saw that a pale cyan mesh surfaced, and under his control, the mesh slowly shrunk, getting smaller and smaller, and finally, it became a small mesh the size of a palm.

The tiny mesh is like a translucent leaf that floats on the water, sparsely scattered on top, dotted with a handful of cinnabar red.

"Alas!" Xiao Su sighed.

"What's the matter, isn't there too little stone harvested?" The cold wind looked at the blood-red sand like cinnabar, which should be the stone.

"My net has been placed here for three whole years, just such a little stone, how can I be embarrassed-"

Xiao Su pouted, not very happy.

Still bent down, lifted the mesh with both hands, looked at the less than fifty grams of stone chips, and felt cold in his heart. A vein that used to produce hundreds of catties of stone annually has now been mined for 50 grams in three years.

"It's a little less, but it's better than nothing!" said Cold Wind.

"Well, this, plus some of the ones I found before, should be enough to build a special steel - a windmill. ”

Xiao Su held the mesh in one hand, took out a white porcelain medicine bottle with the other, and carefully turned the small pinch of stone into the white vial. I didn't even dare to take a breath of the atmosphere, a little bit, one by one, for fear of scattering a single grain.

Seeing Xiao Su seal the cork of the white porcelain vial, he spoke.

"Why do you have to work so hard to buy some on the black market, aren't you?"

"The price of the stone on the market is too high, and almost all of them are of high purity, or the purity of the raw ore in nature is relatively high. ”

"Only by finding new veins of epithelia can we alleviate the plight of the lack of epithet in the entire Eastern Continent. Han Feng looked up at the bright sun, his eyes narrowed into a line, and said, "It's almost noon, let's go back." ”

"Well, it's been a busy morning. “

The two of them, with a slight leap, flew to the upper edge of the mine.

Walking slowly along the path from which he came, he disappeared into the dense artemisia bushes—
