Twelve gray dwarf zombies struggled desperately in the Five Elements Sword Formation, constantly attacking this sword array space, Song Jian frowned slightly, he found that this sword array space actually had an existence similar to a blood trough, and after being attacked, he and this sword array space actually lost blood together;

"Fog grass, the five elements of the sword array are running, endlessly, until the death is closed, damn this until the death is not only referring to the attacked monster, but also me?" Song Jian was surprised.

Once the Five Elements Sword Formation is deployed, then if all the monsters in the sword array space cannot be strangled, the monster's counterattack will also kill Song Jian;

It's just that the attack damage in the sword array space is extremely high, and through the sword array space, the monster's attack on Song Jian has been weakened a lot, which is enough to last for a long time;

Song Jian could see that in the gray mist of the sword array space, countless sword lights were shining, and with every damage, more than seven hundred points of damage floated above the heads of these monsters, and some even appeared with critical hits, the damage of the Sky-Breaking Sword was divided into five, but it did not reduce the damage, which was equivalent to five Five Elements Sky-Breaking Swords attacking these monsters;

It didn't take long for Song Jian's qi and blood value to drop to about half, and the twelve gray dwarf zombies in the space of the Five Elements Sword Array were all killed, and the items on the ground were exploded;

The gray sword mist slowly disappeared, and the Five Elements Heaven-Breaking Sword returned to Song Jian's hand, and the "Five Elements Sword Array" in the long sword attribute turned gray and entered a cooling state.

"The power of the Five Elements Sword Formation is huge, at least it is much stronger than the Ten Thousand Swords Flying Immortals, but it should be used carefully, if it is used well, it is a sharp weapon, and if it is not used well, it is simply suicide!" Song Jian thought with palpitations;

Twelve gray dwarf zombies, blasted down three pieces of magic crystal ore, and at the same time there were some materials and green equipment about level 40, after Song Jian picked them up, he continued to walk towards the mine;

As soon as he entered the cave, Song Jian felt a wave of heat and rushed towards him, the temperature in this cave was dozens of degrees higher than outside, giving Song Jian a sense of familiarity in the abyss and hell;

However, there is no abyssal aura that is ubiquitous in the abyss hell here, and the aura of fire is extremely pure;

Entering the cave, Song Jian found that the cave had been hollowed out entirely, and an extremely large underground castle had been built, which looked as if it was inhabited by giants, both the open castle gate and the hall inside were extremely wide, not at all like a gray dwarf who was only twelve or thirteen years old;

Song Jian shook his head, and when he entered the cave, he found that this was indeed a magic crystal mine, but the magic crystal ore at the entrance of the cave was extremely poor, and the quality was not high, giving people a feeling that it was a pity not to dig and a waste of effort to dig;

"The magic crystal ore at the entrance of these is even worse than the magic crystal ore dropped by hunting these gray dwarf zombies, there is no mining value at all, it is better to go to this gray dwarf's underground castle to have a look, maybe there will be a surprise!" Song Jian said secretly in his heart, just glanced at the magic crystal ore at the entrance of the cave, and continued to walk forward;

There are a lot of gray dwarf zombies in the castle hall, and among them, there is also a forty-fifth level lord-level monster, holding a two-handed sword like the door panel, constantly walking back and forth in the hall;

There are so many monsters here that they are extremely dense, if you want to lure them out one by one, I'm afraid it will be very difficult, and it will be easy to overturn, Song Jian hesitated for a moment, and decided to bypass them and explore them first;

If there is really a rich storage of magic crystal ore here, then gather the players in the battle alliance to clear the monsters here, if the magic crystal ore inside is not as rich as imagined, then it is okay not to come here;

At the end of the hall was a very small door, which matched the size of the gray dwarf, but if you wanted to get there, you had to go through the hall, and it would inevitably alarm the monsters;

Song Jian's heart moved, and he used the hidden necklace's own skill, the abyss concealment technique, a faint abyss breath, diffused from the necklace, covering Song Jianjian's body, and Song Jianjian's shadow suddenly became transparent;

The gray dwarf boss in the center of the hall seemed to sense something, and sniffed vigorously in the air with his head held high, but he didn't find anything, and suddenly became furious, constantly roaring, and moving more and more frequently.

An ordinary gray dwarf zombie monster couldn't dodge and blocked in front of it, and was immediately kicked out by this boss and slammed into the pillar of the hall;

Bang~

This huge stone pillar, which was thick and needed to be hugged by several people, shook slightly, and some gravel fell from the top of the pillar, causing the ordinary gray dwarf zombies around to quickly dodge to the side;

Song Jian's eyes lit up, the stone pillars in this hall didn't seem to be as strong as they looked! Looking around, there were thirteen of these thick stone pillars in the entire hall, and if these stone pillars were to be made like this one, then only half of them would need to be destroyed, and the entire hall would collapse, while still retaining a small area of safety;

"If you really want to clean up this place in the future, these stone pillars may be the key to killing these monsters!" Song Jian smiled slightly, remembered all this, and slowly touched towards the small door at the end of the hall;

Because of the riot of the gray dwarf boss, all the ordinary gray dwarf zombie monsters around them panicked and ran around, which made it more difficult for Song Jian, who was in a stealth state, to enter the small door at the end of the hall and enter it.

A gray dwarf zombie was originally about to run forward, but when he heard the roar of the gray dwarf boss, he was frightened, and suddenly turned his head and rushed in the direction of Song Jian, who was in a stealth state;

Song Jian was stunned for a moment, it was too late to dodge again, and subconsciously cast a soul walk, and the monster passed directly through Song Jian's body, rushed forward two steps, and then turned around and ran in another direction;

Song Jian felt the monster pass through his body, and with a slam step on his feet, he actually rushed directly towards the small door at the end of the hall, and in more than three seconds, coupled with Song Jian's acceleration state, he actually passed through the hall directly and entered the small door at the end of the hall;

Behind the small door is a zigzag passage, Song Jian entered the passage, at this time there was a trace of fear, just a little carelessness was to lead to all the monsters to besiege, with his current strength, it was impossible to survive;

"Huhu, I didn't expect that in the stealth state, I could also perform a soul walk, and under the superposition of a skill, this made my survival and escape ability increase a lot;" Song Jian recalled the state just now, and couldn't help but show a smile on his face;

At this moment, Song Jian suddenly heard a faint sound of metal hitting in front of him;

"Bell, bell......"
