It took only two days to complete, the leap from the first realm of the Seven Kills Sword Technique to the second realm!

The first realm, the sword, moves with the wind!

The second realm - the sword, move against the wind!

Zixiu didn't tell Su Daozhi the happy news as soon as possible, because he didn't know where Xiao Su had gone. I learned from Mr. Su San that it turned out that early in the morning of the second day after Xiao Su returned to the Five Elements Sect, he went to a valley outside to look for an ore material.

According to Xiao Su's idea, to increase the speed of Windranger 3.0 to 0.3 times the wind speed, or higher, in that case, the pressure on the structure of the windmill itself has almost doubled, so it is necessary to add some special ores to the steel frame of the windmill to enhance the toughness of the body body.

Under the guidance of Mr. Su San, he traveled along a small ravine, in the direction of the rising sun, following in the footsteps of Xiao Su.

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, were spotlessly clean.

Because of the narrow terrain of the valley, the eye only shines in at noon, so the tall and fluffy artemisia grass is covered with sparkling dewdrops. Zixiu didn't go far, the clothes on his body were wet, and the wet fabric was close to the skin, slippery and greasy, very uncomfortable.

The dim and dark canyon, with no end in sight, looks up and is surrounded by cliffs on both sides, angular rocks, large or small, horizontal and vertical, 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 Mr. Su San, the place where Su Daozhi went was close to the pass of a waterfall, and when he heard the sound of falling water, he arrived.

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

I saw a huge mine pit, on the cliffs all around, the ancient trees towered to the sky, the huge rocks stood steeply, the waterfall was overhanging, the flying stream went straight down, the momentum was extraordinary! The surrounding verdant green, surrounded by mountains, the strange rocks were craggy, the strange peaks were inserted into the sky, what 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 under the cliff!

At the bottom of the pit, the flowing water of eight waterfalls converges to form a huge pool, a striking whirlpool is located in the middle of the deep pool, because it is surrounded by mountains, the water in the deep pool does not flow out, the water accumulates into an abyss, and the bottom of the deep pool, connected to the dark river, forms a funnel-shaped whirlpool.

"Xiao Su!"

I saw a familiar little man, standing on the edge of the pool.

He induced the power of the Yuan Infant, stretched his arms, and jumped down.

Control the rhythm of the fall, glide through the air like a bird, and land firmly behind Xiao Su!

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 Xiu, 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'm here to see you, what rare materials are you looking for, and you want to come here!" he and Xiao Su stood together, stepping on a big rock.

Xiao Su shook his head embarrassedly: "A mineral called Limestone, 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." Looking at his smiling appearance, Xiao Su immediately asked, "You are so free, you came here to find me, isn't it, your Seven Kills Sword Technique last night has risen another level!"

"Exactly!"

He grinned, looked relaxed and confident, and touched the back of Xiao Su's head!

"It's amazing, you have reached the second level of the realm so quickly, it seems that there is still a lot of hope for you to raise the realm to the fourth level before the Yuanying duel!" Xiao Su bared his teeth, very happy.

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

"It's just luck!"

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

"Look at what you've been doing for a long time, aren't you here to mine rock?" he asked, looking at the pool of clear water.

"Get off the net!"

At first glance, he didn't understand, and he laughed: "What, are you netting?"

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.

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

Hearing this, he was a little confused, he also frowned, and asked: "What kind of fish are you going to catch, is it difficult to catch, a net has been placed under the water for three years, it is estimated that it will rot long ago, right?"

Xiao Su was staring at the bottomless, rippling pool, and looked back and smiled: "Brother Xiu, I'm not catching fish, I'm mining, my net is not an ordinary net!"

Mining!

"What do you say, you're mining with nets?" he grinned, thinking it was too funny, he had never heard of it, and there were those who mined nets under the water.

"Yes, I have laid a dense net here with the Five Elements True Qi, and some fish and ordinary sand and stones can pass through, but there is a kind of ore debris called '碜' that will stick to the net. ”

Xiao Su raised his head and smiled, the stone he said 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 slime!" he suddenly realized.

"Brother Xiu, do you know that this pit where we are located used to be the largest stone mine in the Eastern Continent, but now, there is no complete 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. It's just that the reserves in nature are too small, and this huge pit was also a hundred-ton giant mine before, but it can't withstand thousands of years of reclamation, and has been exhausted and abandoned!

He nodded, looked around at the empty and barren four walls, and said with a smile: "It's hard for you, I thought of using a net to filter the slag, this local method!"

"Collect the net!"

Su Daozhi waved his little 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 it, dotted with a few dots of cinnabar.

"Alas!" Xiao Su sighed!

"What's the matter, isn't there too little stone!" he looked at the blood-red sand like cinnabar, which should be a stone.

"I've been putting this net here for three whole years, and it's so painful!"

Xiao Su pouted, not very happy, but still bent down, lifted the mesh with both hands, looked at the stone fragments that were less than ten grams, and felt cold in his heart. A vein that once produced thousands of catties of stone every year is now a few grams in three years and has been abandoned, which is a matter of course.

"It's a little less, but it's better than nothing!" he said comfortingly, a little crying and laughing.

"Well, this, plus those few grams I found before, should be enough to build a windmill!"

Xiao Su held the mesh in one hand, took out a white porcelain medicine bottle with the other hand, and carefully turned the small handful of stones into the white vial, not even daring to take a breath of the atmosphere.

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 adulterated, or the purity of the raw ore in nature is relatively high!" Xiao Su explained.

"It seems that in order to make more windmills, we must find a new vein of stone!" He looked up at the roaring sun, his eyes narrowed into a line, and said, "It's too hot here, let's go back to the Five Elements Sect!"

"Okay!"

The two of them, with a slight leap, flew to the upper edge of the pit, followed the path they had come, and soon disappeared into the dense artemisia bushes.
