After just a few breaths, Mu Qingyun was already sweating profusely, panting heavily, but the evil spirit captain was not tired at all, still attacking with punches and kicks, although the move was simple, but the power was huge, Mu Qingyun did not dare to resist, so he could only dodge everywhere in embarrassment.

Seeing that Mu Qingyun's situation was not good, Hu Ming's eyes already showed a look of worry. "Don't worry. Si Yi gently touched Hu Ming's head and calmed it down. "This kind of martial art has a time, and this evil spirit captain is not a creature of our world, here, it is rootless water, and it is impossible to maintain such a high-intensity attack all the time. ”

As if to verify Si Yi's words, after a few breaths, the attack speed of the Evil Spirit Captain decreased slightly, although the decline was very small, but Mu Qingyun, who had been nervously observing the attack of the Evil Spirit Captain, still keenly discovered this. Turning the long stick in his hand, Mu Qingyun said with a smile: "Big guy, you must be tired from fighting for so long just now, I'll send you back." ”

After speaking, Mu Qingyun suddenly accelerated and approached the Evil Spirit Captain. It turned out that he had been holding back just now, just to wait for this moment to erupt. Seeing the gap between the attack of the evil spirit captain, Mu Qingyun supported it with a long stick, and with the help of the shock force of the long stick, he jumped high. Looking at the giant's head below, Mu Qingyun raised his long stick and roared: "Zhenshan stick, give me death." ”

The giant's reaction had slowed down, and with his current speed, he could no longer resist this shot, so he could only helplessly watch as Mu Qingyun's iron rod fell from his head, and then slammed it on his head.

"Boom!"

A loud crash resounded through the space. Si Yi hurriedly covered his ears, and Hu Ming also bent down and covered his ears with his two front paws.

When the sound passed, Si Yi and Hu Ming raised their heads and looked at the scene in front of them, their faces full of surprise. The majestic Captain of the Evil Spirit just now has now become miserable and inhuman, and Mu Qingyun is also a little tired from the stick that broke out just now, and now he can't stand up, so he can only lie on the ground to rest.

Si Yi hurriedly walked over and helped Mu Qingyun up, and said with a smile: "Actually, you don't have to fight like this, as long as you hold on for a dozen more breaths just now, the Captain Evil Spirit will decline in strength because he can't absorb the aura in our world, and he will naturally disappear in the end." ”

Although Mu Qingyun already felt that he had no strength in his body, when he heard Si Yi's words, he still insisted on raising his head, tried hard to give Si Yi a roll of his eyes, and asked in an almost inaudible voice, "Then why didn't you tell me just now?"

Si Yi turned his eyes to the side, pretending to be looking at something else, and whispered, "Forget." Mu Qingyun was almost angrily recited by Si Yi's words. Helping Mu Qingyun to the open space on the side, after he had recovered some physical strength and spiritual power, Si Yi began to walk forward.

The secret realm is very small, except for the huge clearing at the entrance, there is only a low mountain left, and at the foot of the mountain, there is a dark cave entrance, I don't know where it leads.

Walking to the entrance of the cave, Mu Qingyun took a few steps forward, stopped Si Yi and Hu Ming, and took the initiative to ask: "I'll go ahead, there may be people from the Heavenly Ghost Mansion inside." ”

Si Yi smiled and waved his hand, "If you want to talk about frontal combat, I can't compare to you now, but when it comes to lurking and camouflaging reconnaissance, I can confidently say that I can throw you ten streets, rest assured, there is no danger in front, there is no one inside." ”

Mu Qingyun obviously wouldn't believe Si Yi's words. Looking at Mu Qingyun's expression, Si Yi also knew that he would not believe in himself so easily, and without explaining too much, he directly entered the cave first. Hu Ming hurriedly followed, but Mu Qingyun was helpless, and he clenched the long stick in his hand and hurriedly followed.

Entering the cave, Si Yi walked to the depths with a relaxed face, Hu Ming followed him closely, one person and one tiger were as relaxed as sightseeing, and Mu Qingyun was full of vigilance, carefully observing the surrounding environment along the way. But there was nothing, there was only the footsteps of himself and Si Yi in the cave, as for Hu Ming, I don't know if it was deliberately controlled, even if he walked in the cave, he couldn't hear his footsteps at all.

As he went deeper, Si Yi found that the temperature around him began to rise slowly, and corpses appeared on both sides of the cave, and if he looked closely, these corpses were exactly the same as the slaves who had just been released outside the secret realm.

"What's inside?Why is the temperature getting higher and higher?" Mu Qingyun wiped the sweat from his forehead and asked with some curiosity.

Si Yi also wiped the sweat on his face and said with a smile: "No matter what it is, but it must be a good thing, you will naturally know it when you go inside." ”

The cave is very deep, and there are many forks in the middle, but Si Yi seems to be extremely familiar with the layout in it, and every time he will choose one of the roads without hesitation, and then walk forward decisively, although Mu Qingyun is puzzled, he can only follow obediently behind.

I don't know how long I walked, looking at the cave wall in front of him that had been burned dark red, Si Yi finally laughed: "We have arrived." After a few more steps, a large hall suddenly opened up in front of me.

Looking at the fiery red spar that seemed to be burning in the cave, Mu Qingyun's eyes lit up, and he quickly rushed out, as if his physical strength had returned to its peak. Carefully knocking down a piece of spar with a long stick, Mu Qingyun briefly confirmed, happily raised the spar in his hand and shouted to Si Yi: "Si Yi, it's a fire soul stone, this is a fire soul stone mine, we sent it." ”

Si Yi took a deep look at the ecstatic Mu Qingyun, and laughed happily: "Yes, I didn't expect that there would be such a good thing in this small secret realm." Looking at Hu Ming's puzzled eyes, Si Yi explained: "The Fire Soul Stone is the fuel that both the second-order refiners and the third-order refiners will use when refining weapons, and the Fire Soul Stone is usually like what we see now, although it exudes high temperature, but we can accept it, but once it is driven by the aura, the Fire Soul Stone can release high temperatures, and it is often used by refiners to melt and process some hard materials." The Fire Soul Stone is a one-time consumable, so its price has been high, and we really picked up the treasure this time. ”

At this time, Mu Qingyun said with a little dejectedness: "It's a pity, even if we know that this is a treasure house, we can't help it, we don't have to think about it to know that the reserves of fire soul stones here must be very high, but if we only rely on the three of us, we don't know how long it will take to mine it." Moreover, this is the territory of the Heavenly Ghost Mansion, and in a few days, the Heavenly Ghost Mansion will definitely find out about the abnormality here and send someone to check it, so the time left for us is not that long. ”

Si Yi smiled confidently: "In seven days at most, we will be able to mine all the fire soul stones in this mountain." There is no need to worry about what you said, and I believe that the Heavenly Ghost Mansion will not be able to react so quickly. ”

Hearing Si Yi's words, Mu Qingyun hurriedly asked, "Do you have a storage spirit weapon?"

Si Yi smiled and nodded. "Not only do I have a storage spirit weapon, but my storage spirit weapon is also very large, there is no problem at all to install the fire soul stones in this mountain, as long as you and Hu Ming Oh are properly reconciled, I am responsible for collecting the mined fire soul stones, with our speed, within seven days, we can completely mine all the fire soul stones." ”

Mu Qingyun laughed and waved the long stick in his hand, and said excitedly: "Then what are you waiting for? Without further ado, let's start acting now." ”

Si Yi smiled and nodded, and Hu Ming also consciously stood behind Mu Qingyun. The division of labor between two people and one tiger is very simple. Mu Qingyun was responsible for using his powerful attack power to smash the cave wall open, and Hu Ming was responsible for separating the boulders that Mu Qingyun had knocked down and finding out the fire soul stones in them. In fact, it has been secretly exchanged for points through the mall.

The cooperation between the two and the tiger is extremely efficient, and the progress is also very fast, the cave is constantly expanding, and every once in a while, there will be a loud bang in the cave, followed by the sound of the tiger scratching on the stone. In order to mine as many fire soul stones as possible before the Heavenly Ghost Mansion reacted, the two of them never stopped working, even when they really couldn't hold on, one of them rested, and the other two continued to mine. With the unremitting efforts of Si Yi, Hu Ming and Mu Qingyun, on the night of the sixth day, the fire soul stone in the vein had been completely mined.

"Ghost Hand Senior, can you help me detect that there are still Fire Soul Stone veins in this mountain?"

Ghost Hand smiled: "You are almost like the bandits, and the fire soul stones in this mountain have been mined by you. ”

Si Yi nodded with a smile, opened his eyes and said: "There are no more Fire Soul Stones here, erase all the traces we left, and then we quickly leave here, nearly seven days have passed, I believe that the Heavenly Ghost Mansion should also react." Mu Qingyun and Hu Ming nodded, and after erasing the traces, the two of them quickly slipped out of the secret realm.

Returning to the cave where he lived before, Si Yi breathed a sigh of relief, this is the safest place, and he finally doesn't have to worry about it. Looking down, Mu Qingyun and Hu Ming had already fallen asleep with their heads down. Si Yi smiled and lay down, he was too tired both physically and psychologically in the past few days.

The next morning, as soon as the sky was getting brighter, a group of men in black came to the valley.

The man in black in the lead commanded: "Investigate the situation near the wooden house, see people alive, see corpses when dead, and record everything suspicious." ”

"Yes. The men in black in the back received the order and dispersed and began to probe the situation in various parts of the valley. The leader of the man in black plunged headlong into the secret realm, and his mission was to investigate the loss of the fire soul crystal ore in the secret realm, which was the main purpose of their visit.

An hour later, the leading man in black walked out of the portal of the secret realm, and with a single blow, he smashed a wooden house into sawdust and flew all over the sky.

Hearing the voice, the other men in black ran over one after another, and the neat line stood behind the leading man in black again.

After a long time, the leader in black calmed his breath, turned around and took off his mask, revealing the old face under the mask. "Tell me, what did you find?"

The man in black standing at the front bent down and said respectfully: "Report to the elder, just now we have found the bodies of all the disciples on duty here, judging from the wounds and the degree of decay, it is initially estimated that the time of death was six or seven days ago, and the murderer had two people and a tiger and leopard spirit pet, one of the two murderers used a spear, and the other should use a blunt weapon with strong hitting power such as a long stick and a heavy hammer. We also found that the bamboo flute that controlled the slaves had been destroyed, and only a small number of slave bodies were found at the scene, and the others should have escaped. ”

The old man known as the elder threw down his sleeves and said with some anger: "Waste, they are all a group of wastes that are not successful enough to fail, the old man has long said that this fire soul stone mine reserves commanded, and an elder-level person should be sent to guard it, but the mansion master just didn't listen, now it's good, people and money are empty." ”

But now is obviously not the time to complain, after thinking about it for a while, the old man immediately made arrangements: "First, go back and gather people to intercept and kill those slaves on the way from Moon Worship City to the Moon Worship Mountain Range, and the affairs here must not be known to others." Second, gather all the clues that can be used, and be sure to find the whereabouts of the murderer, our Heavenly Ghost Mansion is not the turn to be bullied by such a child. ”

"Yes. The men in black agreed, and dispersed, and the old man quickly left, and the valley was silent again.
