After learning that Yu Bin came to the rescue, Lei Guang and Keldila consciously controlled their online time to ensure that when the rescue began, they would have enough time to escape. They woke up every two hours, trying to observe their surroundings as much as possible without alerting the fanged druids, and providing some information for Yu Bin and Alan to refer to.

At this time, it was the third day after Yu Bin and Ailan converged, and after two days of careful exploration, Yu Bin roughly grasped the nearby terrain and situation.

The entire Fangs Abyss is very large, and Yu Bin's location is only one of the entrances and exits, and this entrance and exit is obviously not valued by the Fangs Druids, under the repeated surveillance of Alan and Yu Bin, only less than five Fangs Druids have entered and exited here in three days. In this regard, Yu Bin is not surprised, the total number of fanged druids is not very large, most of the druids who followed Nalarex here have been eroded by the dark power from the Emerald Dream Realm, many have become irrational puppets, and only a small number still maintain enough intelligence to perform some simple actions, which is one of the reasons why Lei Guang and Keldila have survived until now. The fanged druids who attacked them were probably ordered to capture as many creatures as they could, as Thunderlight had confirmed through observations, and in addition to him and Keldilla, the fanged druids had also captured a number of velociraptors, plains lions, and big-toed ostriches, all of which were common species living in the barrens.

"Now it's certain that those two guys are being held here." Alan curled up and pointed at a piece of parchment, which depicted the terrain in the abyss of the fangs with simple lines, which was the result of Alan's continuous exploration in the past three days, although it was very rough and many places were large blanks, but it was already a very good map for Yu Bin. "From this entrance, you have to cross two rock platforms and a stone bridge, there are a lot of braziers, I'm afraid it's hard to hide your body, and here, there are two fanged druids guarding them, there should be another passage behind them, but I can't touch it."

Yu Bin's memory was not strong enough to remember the terrain in the depths of the Wailing Cave clearly, and it was already good that he could roughly determine the location of the Fangs Abyss.

"From here?" He pointed to another entrance, the most difficult of the four they had found, the low passage almost crawling through, and even the wind snakes were reluctant to enter or exit from it.

Alan shook his head, he and Yu Bin were now hiding in a narrow hole, after sealing the entrance of the hole with stones, they could light torches inside without being discovered: "No, it is a snake nest that can't climb far from there, even if we find a way to end that group of poisonous snakes first, the exit connecting to the inside is also on a small high platform, you can go in, it is impossible to come out of there, the height is too high, you can't jump up." ”

"Then it looks like the only way to get in is from here." Yu Bin pointed to another entrance, the widest of the four entrances and exits, and the only one where the fanged druids could be monitored.

"Why don't you choose Exit 2? Although it was a little far from the place where Lei Guang and the others were being held, at least no one was found to be in or out. ”

"No, after entering Gate 2, there is an unobstructed platform, and it is exposed under the high platform on the other side of the underground river, and the two fanged druids you mentioned before don't even need to turn their heads to see us!" Yu Bin's rich experience made him rule out this seemingly very tempting choice early, "Only here, we have only seen a total of five fanged druids in and out in the past few days, and three of them are still the same person, which shows that they are not patrolling, but have other purposes, so I think that as long as we seize the opportunity, we may follow behind and sneak in." ”

If it is not a last resort, Yu Bin does not want to fight these fangs druids head-on, although they have lost most of their IQ due to the erosion of darkness, but the druids who can follow Nalarex to come here will definitely not be too low, no matter how weak they are, they are much more powerful than Yu Bin and Alan, not to mention that these fanged druids are still wearing complete equipment, Yu Bin is not absolutely sure that he can kill them quietly in a short time. And once spotted by these fanged druids, any bit of noise in the silent underground cavern will be amplified to attract the attention of the other party.

"Well, when will you do it?"

"It's eight o'clock in the evening, and in three hours, the wind snakes will go back to their nests and sleep. I will continue to monitor there during this time, you immediately go offline and contact Lei Guang and them, and go online on time in three hours, let's do it! ”

Alan Liso put away the parchment and blew out the fire extinguisher: "Okay, I'll let them know right away!" ”

Three hours later, Alan squatted beside Bin, observing the entrance of the cave not far away through the crack in the rock, the two-person high entrance revealed a dim yellow light, and the light generated by the brazier in the cave could only extend to the area around the entrance, and under the light, the place where Yu Bin and Alan were hiding was even more difficult to find.

"Do it?"

"Wait!" Yu Bin stretched out his hand to stop Ailan, "There is movement!" ”

It didn't take long for a group of fanged druids in leather armor to emerge from the cave, their blue-blue skin and pointed ears indicating his identity, but Yu Bin found that their eyes were empty and blank, as if they had lost their souls, and they didn't care about their surroundings, just striding in one direction.

"Strange, how could so many fanged druids leave the fanged abyss?" With just a cursory visual inspection, Yu Bin knew that there were at least twenty of these fanged druids who came out of the abyss of fangs, which was not a small number.

Alan was delighted: "That's good news! Leaving so much at once means that the number of people staying there is decreasing! ”

Seeing those fanged druids disappear into the darkness little by little, and the footsteps gradually disappeared, Yu Bin tightened his belt, for ease of movement, he was not wearing that heavy armor now, only a light gray cloak on his body, in the dark cave, this color is more conducive to concealment.

"Let's go!"

The two of them jumped out of the hiding place one after the other, hunched over to the entrance, and looked inside.

As far as the eye could see, there was a wide platform, and in the distance you could see a shadowy rock wall and a stone bridge that spanned the air, and several braziers were set up throughout the platform, perhaps because of the lack of fuel, the fire light was a little small, which made some areas of the platform appear to be clearly shadowed.

"Good luck!" Alan whispered, and took the lead in stealth, trotting a few steps into the mouth, and advancing against the rock wall where the fire could not reach.

The stealth used by Alan is not completely invisible, and to achieve that effect, skill alone is not enough, and the power of shadow magic is also required, so almost every powerful assassin is a shadow master, and his control of shadow power is not inferior to that of a mage who is proficient in this way. Alan can only rely on a specific environment and shadow to greatly reduce his sense of existence, and through the reasonable configuration of the color of the equipment, to make himself as integrated with the rock wall as possible, Yu Bin believes that it is not so much stealth, but rather a protective color, similar to the effect produced by camouflage uniforms in reality.

Of course, as Alan moved slowly, Yu Bin could see that there were some shadow patches covering Alan's body little by little along the rock wall, which showed that Alan had begun to mobilize the shadow power in his body to hide himself, and when he was able to completely cover his body with shadows, it was time for him to completely master the skill of shadow protection.

Compared to Ailan, Yu Bin is much more relaxed, his gray cloak can have the same effect as Ailan's shadow protection, and his rich experience allows Yu Bin to know which position is just the right place to use the blind spot.

Moving all the way along the rock wall, Yu Bin easily extinguished the two braziers, making the shadow area even larger, and after turning a corner, Alan pulled out the dagger on his waist like lightning and stabbed it backhand in front of him. It turned out that a venomous snake was lurking behind the corner with its body crossed.

Alan's dagger pierced the seven inches of the poisonous snake accurately, and then cut off the snake's head, the poisonous snake that became two halves was still rolling its body, the bloody snake head was spitting snakes, Yu Bin stepped forward and stomped the snake's head flat with one kick, and Alan also reached out at the same time to straighten the snake's body and threw it towards a brazier not far away.

The flames quickly devoured the body of the poisonous snake, and Yu Bin squatted down and hid the flattened snake head under a stone: "You go over there, find a way to extinguish the two braziers, and I'll deal with the two beasts!" ”

The beast that Yu Bin is talking about is two wind snakes guarding not far away, this creature has a venomous snake-like body, and the upper body also has wings composed of skin membrane and cartilage, which looks like a cobra wearing a leather scarf.

Ailan nodded, turned around and walked towards the two braziers, Yu Bin adjusted his body, taking advantage of the slight staggered sight of the two wind snakes, kicked his legs, and pounced on one of the wind snakes with a charge, when the person was still in mid-air, the heart devouring in his hand flew out, accurately penetrating the head of the other wind snake, and nailed it to the ground.

With the extension of his right hand, the palm holding the black-winged blade was directly stuffed into the open bloody mouth of the wind snake, and regardless of the feeling of being bitten by the fangs, the black-winged blade in his hand was pulled one by one, and quickly cut the mouth of the wind snake in half, lest the beast make any sound.

With his left hand, he took out a bottle of antidote from his belt and poured it down, and without stopping his movement with his right hand, the Blackwing Blade deftly turned in a different direction, penetrating the wind snake's brain from the bottom up, turning it into a corpse.

At this time, Ailan's side had also successfully extinguished the two braziers, lost the firelight, and the corner where Yu Bin was located was completely shrouded in darkness.

"It's strange, there are so many fewer guards today!" "I thought there would be at least a few wind snakes guarding those two braziers, but I didn't expect any of them!" ”

"Well, I also find it strange, it looks like something must have happened inside the Fangs Abyss! Can you see those two fanged druids from here? ”

Alan grabbed the bulge on the rock wall and climbed up a few steps, poking his head out slightly: "I can see it, but there is only one, and the other one is gone!" Could it be the one who just left? ”

"I don't have time to care about that much!" As Yu Bin spoke, he had already tied a rope firmly to a groove in the rock wall, "No matter what, we must rescue Lei Guang and Keldilla!" I'll go down first, and if there's no danger down there, I'll shake the rope twice! ”

With the help of the rope to descend to the next platform, Yu Bin found that there was only one fanged druid guarding here, and judging from the opponent's stiff body and stiff movements, it was obvious that it was a fanged druid who had completely turned into a dark puppet.

Without hesitation, he jumped down from the rope and threw the fanged druid to the ground, the heart devouring in his hand pierced the opponent's heart from behind at the same time, and the blackwing blade in the other hand slit the throat of the fanged druid, but this still could not make this dark eroded elf die, and when he lost his self-consciousness, the body had actually turned into a corpse, and the corpse was obviously not of any significance.

Yu Bin hates this kind of enemy like a flesh and blood puppet, they are neither living nor non-living things, strictly speaking, these puppet fanged druids have become the same constructs as gargoyles, whether it is a heart or a brain, it is just a part of the body, and the power to control them comes from the dark power in the body, and if this dark power does not disappear, this body still has enough combat power.

The throat was slit, so that the fanged druid could not make a sound, but he still immediately launched a counterattack against Yu Bin, and the knife in his hand stabbed Yu Bin in the back, while his legs kept stomping, trying to get up from the ground.

Yu Bin ignored the knife that pierced his body, and directly elbowed the head of the fanged druid, and the impact directly broke the opponent's cervical vertebrae, and the whole head tilted to the side as if it had lost support.

But even so, this fanged druid still didn't die, but the next moment, a scorching flame rushed directly into his body along his throat, it turned out that Yu Bin had already put away the blade of the black wing, and stabbed the soul into the opponent's throat that was cut, because the cervical vertebra was broken, the throat that caused the incision was wide open, so that the flame power of the tip of the soul directly filled the entire body along the throat, and the surging flames continued to consume the dark power in the body of this fanged druid, Yu Bin could even see with the naked eye a trace of black gas diffusing from this corpse, quickly dissipating into the surrounding air.

"How do I think you're more of an assassin than I am?" Ailan, who couldn't wait for Yu Bin to send a signal, happened to witness the whole process of Yu Bin's killing of the fanged druid, and the clean and neat movements made Alan very embarrassed as an assassin.

"At least I won't sneak!" Yu Bin put away his weapon, dragged the body to the corner, and took the lead towards a dark passage not far away.
