As I walked to the entrance of the cave, the thick yellow smoke still pierced my nostrils and made me dizzy.

  Levin quietly activated 【Shadow Form】, his entire body's shadow became blurry, his skin turned gray, and even the 【Ultimate Frostguard】 leather armor he wore also changed to a dark color, making him a half-misty shadow entity.

  In shadow form, Raven can't attack, but as long as there's an opening, Raven can slip through like smoke. From a sealed air vent next to the main entrance, Raven finds a fingernail-sized vent and slips inside.

  Along a small mountain cave with only fist-sized and winding paths, Raven went straight into the depths of the cave.

  After walking about a hundred meters, Levin arrived at the main cave. With the help of his half-elf innate dark vision, Levin saw layers and layers of bat corpses on the ground. The deeper he went into the cave, the smaller the corpses became.

  In places where sulfur balls didn't reach, Raven can no longer see the existence of corpses.

  Just as Lewin had guessed, all the survivors had fled to a deeper place for shelter.

  Another hundred meters down, the smell of sulfur was already very faint. You could see a dozen or so bat-like creatures with what looked like gas masks helping each other clean their bodies.

  The Dark Knight has created many special items for his own use, such as this breathing mask: This mask covers the user's face. It is equipped with goggles and a packet of alchemical substance, allowing the wearer to breathe for up to 4 hours. With this mask, one can be immune to the effects of harmful smoke and inhaled toxins. The mask also allows the wearer to survive underwater or in an airless environment.

  Batman wasn't choked to death, probably thanks to this thing.

  A death sentence can be commuted, but a life sentence is hard to escape.

  That group of foolish vampire people attempted to use a bucket of water to extinguish the burning sulfur, probably because they didn't know that when sulfur meets water it causes severe flowing fires or violent boiling.

  So most of these batmen have burn marks on their bodies.

  Leiwen roughly estimated that these demonic bats' health was only around three-fifths left.

  That's enough!

  Take advantage of its illness and go for the kill!

  Riven swiftly switches from Shadow Form to Flame Form, the shadows around her body rapidly deepening, black flames bursting out of Riven's body, enveloping and protecting her.

  System Prompt:

  "You enter the [Shadow Flame Form]. In this state, you gain 10 points of all resistance and all creatures that hit you with melee attacks take 20 points of fire and shadow damage."

  At the same time, Raven directly released a charging phantom, and his own body tried its best to keep up with the phantom's movements.

  Yes! Raven cultivates [Primary Phantom Gale Step] in battle.

  Levin had long discovered that the speed of mastering martial skills in battle was three times faster than in training state. No matter how much he trained, if he couldn't use it in battle, it would be a waste, but if he could use it in battle, then there must be no problem during training.

  Batman was stunned by Raven's sudden attack.

  They couldn't imagine how Raven had evaded the sentries they'd set. They shrieked loudly, both to alert their companions and to unleash ear-piercing sonic blasts at Raven.

  "The bat-like creature has launched a Will save [Despair] against you: If you succeed on a DC 16 Will save, you avoid the sonic effect's mind-affecting effects. Otherwise, you take a -2 morale penalty to saving throws, attack rolls, ability checks, skill checks, and weapon damage rolls for as long as the bat-like creature maintains concentration on its sonic disruption against you (20 seconds)."

  "Your [Iron Will] specialty gives you a +3 bonus to will saves... Save made... You succeed on the will save, and are not affected by the vampire bat's sonic attack!"

  Raven's accumulated immunity attribute has finally come into play. This gave Raven a foundation for an all-out burst.

  Phantom Clone Slash!

  In his heart, he silently chanted and Raven swiftly sprinted again, releasing three more illusory clones.

  One body four splits, simultaneously attacking the Devil Bat Person.

  Don't be fooled by the powerful appearance of the Devil Bat, it's just a Bronze-tier monster at its peak. In reality, they're just a group of strong but inexperienced turtles.

  When have they ever seen a person split into five in an instant and then come at them together?

  Before the bat-like creature could reveal its shocked expression, the five Raven's figures suddenly accelerated, and the five Black Moon Blades struck the bat-like creature simultaneously.

  Two knives inserted into the eyes, one knife cut off the throat, one knife pierced through the heart, and another knife entered from the left temple and exited from the right temple.

  Leiwen unexpectedly ignored the Phantom Swordmaster's "Three Dragon Bite" and "Four Dragon Bite", directly unleashing a "Five Dragon Bite"!

  The system prompt Raven didn't have time to look, he knew that the proficiency of 【Three Dragons Devour】 must be soaring up rapidly.

  The Mantis Man next to him was stunned, and it took three seconds for him to raise his fork high and try to smash it into Raven's forehead.

  A Scythe, a strange double-headed weapon invented by the Vampire himself.

  For this excellent-grade weapon equivalent to +1 bronze equipment, Raven is quite unimpressed. For Raven, the only purpose of Fork exists is for him to practice 【Iron Flash Slash】.

  A flash of knife light, under the astonished gaze of the Devil Bat, that hardwood stick as hard as tempered iron was cut in two by Raven with one slash.

  It was afraid, and its instinctive fear caused it to start shrinking back.

  Lei Wen didn't give him a chance to escape and rushed forward to add another blow.

  Death!

  System Prompt:

  "You have killed a level 36 Bat Demon alone, extracting the target's soul energy. You gained 1300 points of slaughter experience."

  Used to killing enemies above his level, a sudden same-level enemy appeared, and his experience suddenly decreased. Leifeng was a bit unaccustomed to this. However, even if the mosquito is small, it's still meat. It's better than just now at the cave entrance, where he killed a large group of magic bats but couldn't get any experience points for himself.

  Raven released three Phantom Clones and swept away the Demon Bats in the area. With this batch of experience, Raven leveled up to 33.

  Glancing at the prompt, Silphi, who had been suppressed to a lower level due to her master's low level, also leveled up to 33. If she were to create Shadow Bee Soldiers now, their initial level would be 26. These soldiers' levels cannot change unless they gain promotions in battle.

  The Batwing is notorious for being a "poor" monster, in the previous game, killing it would not yield any gold drops, and the dropped items are calculated as half of those from monsters of the same level.

  Leiwen didn't have time to sweep the battlefield and continued to advance towards the depths of the cave.

  The slope's gradient became gentler and gentler, after walking for over 50 meters, finally reached the bottom of the cave, where there was a large area of flat ground.

  Of course, the focus won't be on the ground either. Just as Raven was about to make a big move, he received a warning from Silphi.

  "My lord, I did as you said. The servants who were guarding the entrance of the Bit Gate have all been killed, and they died in a terrible way."

  Describe it.

  Xilphi told Raven everything she sensed.

  Levin hesitated for a moment before severing his spiritual connection with Silfi.

  "Is that really him?" Glancing up at the stalactite above his head, Raven sneered: "Let you guys live a little longer."

  Raven seemed to have dug something on the ground and returned along the original road.

  Just over 200 meters away, Raven suddenly made an emergency stop and flipped empty, dodging something.

  The next second, another sudden stop and turn, this time Raven rolled over awkwardly, rolling three times before stopping.

  "Heh heh...... quite impressive, little Raven." A ghostly voice echoed in the darkness.

  Leiwen stood up, dusting off the dirt on his body, and said disdainfully: "What? Want to see me in a panic? Or want to hear me scream who you are in terror? What exactly are you?"

  "You..." The other person was momentarily speechless.

  "But you're just a petty thief of breath. Apart from lurking in hiding, waiting for prey to approach and then pouncing to steal the air from their lungs, what else can you do?"

  "Exposed by Raven's single sentence, the Sneak Breath was greatly shocked, but after just a few seconds, it laughed again: "Not bad eyesight, huh? You actually know I'm a Sneak Breath. So what? My Lord Arangsu is a being from the Wind Element Realm. To you, I am just a gust of wind. As an assassin, you have no means to attack me. What if my sneak attack failed? I can continuously launch attacks on you for three days and three nights without stopping, and as long as you fail to dodge once, you're dead! Hehehe!"

  "Take advantage of being able to laugh now and laugh a few more times. I think you won't have the chance to laugh again in the future." Laiwen retorted coldly.

  "Hahaha! You stinky little brat, what big talk. Later I'll suck the air out of you. I want to make you watch as your limbs lose their air and wither away, watching your flesh shrivel up. Hahahahaha! Ah——how did you discover me?!"

  Suddenly pounced on by Raven, something was lost on his body, and a strange cry came out of the strange breath.

  "Idiot! Now the whole mountain cave is filled with floating sulfur powder, where there is a blank space, you are right there."

  He was so shocked and amazed, he really didn't know that this was the reason why he had nowhere to hide.

  It realized it was time to retreat, or things might develop in a direction it didn't want. It began to flee at full speed.

  However, more and more sticky things flew out of Raven's hands and hit it on the head. The more they hit, the heavier its body became. It started as just a mass of energy, but now it looked like a piece of dough floating in mid-air.

  "What is this!?" The thief gasped and shrieked as he tried to struggle free from this icy breath.

  "This is Frostfire: a bonding agent created by the Mor'bai. It absorbs heat when exposed to air or moisture. And of course, it also inflicts minor frost damage. Not much for ordinary humans, but for you... Hehe!" Raven smiled as she approached the gasping creature that was now moving slower than a snail.

  He raised the Black Moon Blade in his hand high up.

  "No - don't kill me."

  "It's too late!" Relying on the "Death Strike Wrist", Raven aimed at the faintly visible core in the midst of the Sneak Attack Monster's gas cluster and stabbed his knife into it without hesitation.

  "Ahhhhhhhhhhh——" The suffocating monster Arlong let out a mournful and miserable scream.

  The system prompt came immediately.

  In addition to having killing experience, there is also an unexpected weird tip...
