On the ninth day of September of the lunar calendar every year, the sun and the moon are counted in nine on this day, and in the "Zhou Yi", six is yin and nine is yang, so it is double yang. Ninety-nine is one, and the yang energy between heaven and earth is flourishing, not inferior to the Dragon Boat Festival. So, Lin Lao chose to set up a formation to guide the mines on this day.

The destructive power of the thunder was extremely strong, and the place where it passed was scorched earth. Therefore, the place where the formation is set up should not be in the city, and the sparsely populated mountainous area should be chosen. More than 800 miles to the north of the capital, there is a barren mountain named Lingwu Mountain, and there are clouds and mist floating on the top of the mountain all year round, so it is named. Lin Lao finally chose the place to set up the formation, because it was not only sparsely populated, but also full of clouds, which was suitable for setting up the formation and guiding mines.

However, because it is inaccessible, we can only rent a car two days in advance to Decheng, which is not far from Lingwu Mountain. Here to replenish all kinds of supplies, buy tents and climbing supplies, and then find a local hunter named Ma Liu as a guide, and the group of three people set out for Lingwu Mountain in the early morning. Because few people come here, the roads leading to Lingwu Mountain are all wild roads, which are walked by local hunters who hunt, and they cannot be opened to traffic at all. We had to walk forward and pack all our luggage into two backpacks, which I carried on my back. I was tossed enough from the exhaustion of the journey, and I had several blood blisters on my feet. I couldn't help but complain to Lin Lao, why do you have to choose such a place where birds don't, can't you just find a vacant land? Lin Lao saw that I was full of complaints, and he was educating me along the way. In his words, I'm still young and I need to exercise, and I don't have the opportunity to exercise like this very often, so I should take advantage of it. I was extremely impatient with the repeated recitation of the scriptures to him, and cursed him again from the bottom of my heart, old thing, if I hadn't asked you...

When Ma Liu approached the top of Lingwu Mountain, he bluntly said that he couldn't take us forward, and there was a taboo here that the locals were not allowed to go to the top of the mountain no matter what. No one can say exactly why, but after so many years, everyone has been conventionally abiding by this rule, and no one has ever been to the top of the mountain. Seeing that Ma Liuyi insisted repeatedly, we didn't force him, from our current position to the top of the mountain, it was only half a day's journey, even if we didn't have him to lead, we could reach it. Moreover, there are few people in our formation to guide the thunder map, Ma Liu doesn't say to go back, and we have to let him go first halfway to prevent the news from being revealed and causing unnecessary trouble.

After Ma Liu left, only Lin Lao and I were left. Due to the fact that Lin is not young, the speed of our march has not been very fast. When the sun set, I reached the top of the mountain. At the top of the mountain is a huge platform, which is full of clouds and mist as far as the eye can see, and being in it makes people feel like they are riding through the clouds. With a wave of your hand, you can catch a cloud.

I couldn't help but ask Lin Lao how he knew about this place. Lin Lao smiled but did not answer, his face was full of reminiscence, it seems that this old man has been here before.

It was getting dark, and Lin Lao asked me to set up the tent first, because the clouds on the top of the mountain were too big, and if I stayed here for a long time, I would inevitably suffer from rheumatism. I set up the tent according to Lin Lao's request, and Lin Lao took another backpack, opened it and turned out a brick-sized box. Lin Lao took the box and shook it in front of my eyes, saying that this box contained the formation base used in the array. I was curious and wanted to take it and take a look, but Lin Lao was stingy this time, and he didn't even let me touch the box. I had to peek at him while setting up a tent on the spot, and I saw that he had pulled out silver nails the thickness of his thumb from the box. The nails were carved with runes, and at the end of the nails was a miniature beast's head, and because it was so close, I couldn't see what it was, but I could only get a general outline.

Lin Lao slapped the nails in the box into the ground one by one, forming a phalanx with a diameter of five or six meters. Then he took out a coil of metal wire from his pocket and threaded it around the beast's head. I didn't look at the rest of the steps, I was busy setting up the tent, and it got dark faster.

When it was dark, Lin Lao and I finally finished the work in hand, and the two of us returned to the tent that had just been set up. I cooked a few bags of instant noodles in an alcohol pot, and the two of us ate a few bites hastily, just waiting for the time to come. The temperature at night in the mountains is very low, and I shiver when I am freezing, it is really not easy to refine a magic weapon, this is a sin. Looking at Lin Lao again, I was happy, this old man was trembling more than me, and the two of us were trembling together as if they were half-bodyed.

When I finally got the son, I was already frozen and fell asleep, Lin Lao got up and wanted to shake me awake, but he shook me for a long time and couldn't wake me up, so he asked angrily: "Do you kid still want to practice the magic sword?" Hearing this, I suddenly came to my senses, and a carp stiffened and stood up violently.

"Hehe, Lin Lao, please, please." With that, I stepped forward and pulled open the tent. Lin Lao snorted coldly and walked out of the tent. I picked up the wrapped core and followed him.

"The texture of the thousand-year-old lightning strike mahogany core is very hard, and it can only be carved into a vessel after being refined by the thunder again. This process needs to be very careful, Xiaoyan, you have to listen carefully. Now put the lightning strike wood in the center of the formation, and then drip your blood onto the wood core..."Lin Lao told me in detail about the process of guiding the thunder, and finally he told me again: "As soon as the thunder passes, you have to run the vitality, depict the sword rune, and hit the sword rune on the sword embryo." There must be no hesitation in this process, otherwise the work will be wasted and the material will be wasted."

I nodded heavily, ripped off the outer wrap of the core, and placed it in the center of the array. Biting his finger, the blood dripped down. To my great surprise, as soon as the blood touched the wood core, it actively seeped in. You know, I've soaked it in water before, but it doesn't stick to it at all, and I didn't expect it to absorb human blood. It seems that the spiritual objects of the innate root nature are really very different from ordinary ordinary things, and they cannot be viewed with common sense.

As I got ready, I walked to a distance of ten steps from the formation and sat down cross-legged, the farthest distance I could touch with my current control of my vitality. Lin Lao patted me on the shoulder and told me to be careful when guiding thunder, so far away it should not be affected by the thunder. But as soon as he had finished speaking, the old man ran into the distance, faster than a rabbit. It made me feel like I was being shaken, wondering if what he was saying was true. However, before I could react, the weather in the sky changed.

When we first came to the top of the mountain, although there were some clouds in the sky, it was not dense. And now I looked up at the sky, and dark clouds were gathering above the minefield. The clouds were constantly rubbing against each other, and the electric light was swimming among them, and I was stunned to see it, as if there was some truth between heaven and earth, which was attracting me. It's just that my Taoism is still shallow, and I can't understand it thoroughly. I patiently continued to watch, taking note of what I saw, and imprinting it into my mind.

Lin Lao looked at me from a distance and was stunned, and shouted anxiously: "Xiao Yan, what are you still doing in a daze, run the vitality, quickly urge the thunder array!" "Hearing Lin Lao's shout, I just came back to my senses from the state just now. Calm down, I pinched two metal wires extending from the lightning guidance formation, ran the vitality in my body, and passed it on. The energy moved quickly along the metal wire, and when the energy was introduced into the lightning array, the beast head on the nail made a whining sound, and then buzzed and vibrated as if it had resonance. I looked at the metal wire in my hand in amazement, such a good air conduction effect, it should be made of pure gold! Old man Lin is really willing to spend the capital, so much gold gets a lot of money.

Now is not the time to think wildly, the thunder is gathering momentum, I put away my mind and carefully observe the situation in the sky. As the beast's head on the ground shook more violently, the cumulus clouds in the sky stirred even more. Lin Lao shouted at me again: "Xiao Yan, quickly put down the golden thread in your hand, the thunder is about to fall, be careful!" ”

As if in response to Lin Lao, the electric light in the clouds slowly converged, and suddenly pierced down like a spearhead. Fortunately, I would have thrown aside the gold wire in my hand a long time ago, otherwise I would have turned into a pile of coke if I was struck by lightning.

Boom~ A loud bang exploded in my ears, and I didn't dare to open my eyes to look at the lightning array, and the light from the lightning was enough to blind my eyes. Then one after another thunderbolts fell, slashing squarely on the wooden core of the lightning guidance array. When the first thunderbolt fell, the wood core was red by the lightning strike, but it was still intact. The second thunderbolt fell, and the core became even redder. Then came the third, and then the fourth, and the thunder rang in my ears forty-nine times before it subsided. I opened my eyes and looked at the minefield, and saw that the wooden core inside had melted into liquid, condensing into a liquid ball. This is the timing that Lin Lao told me, only by taking advantage of the liquid state to play the sword talisman and cast it into a sword weapon.

I tried to quickly get up and run towards the formation, but when I stood up, I found myself limp, and I fell to the ground with a pop. It turned out that it was the aftermath of the thunder just now that shook my body, but I didn't notice it. I couldn't stand up with all my strength, and I was anxious to see the liquid slowly cool and the best time to make a device was about to pass. After so much effort, is it just in vain?

Lin Lao ran over from a distance, picked me up, and said anxiously, "What's wrong?" Why don't you go soon! "I had to tell him that I was so injured by the thunder that I couldn't walk at all. Lin Lao hated that iron could not be made of steel and said: "Out of the Yin God, out of the Yin God!" Do you need me to remind you? ”

Hearing this, I didn't dare to delay, sat cross-legged, pinched my hand, and a spiritual light flew out from above my head, which was my yin god. However, there is something wrong with its current state, it does not appear in the form of a human, but like an elixir. Lin Lao is just a mortal with the naked eye, although he sensed my Yin God with his powerful spiritual power, he couldn't see what it was like at all.
