The cobwebs just now directly shrouded a rock behind Hong Yi, and in an instant, it was like pouring sulfuric acid, and it was corroded one after another, emitting a pungent smell.

Seeing this scene, Hong Yi's face darkened, and he secretly said that if he hid a little slower, he was afraid that he would be directly hit, and he would be seriously injured at that time, and he would be trapped by the kind of cobweb that was comparable to a steel wire, and he couldn't even run.

With a quick thought of tactics in his mind, he immediately took out an arrow and drew his bow and shot it.

This is an ordinary alloy arrow, and the power at this distance is almost the same as that of a bullet, but the next moment something happened that stunned Hong Yi, this arrow was actually bounced off by the shell of this spider mutant, and the alloy arrow only splashed a spark on it, leaving a dent that was not deep or shallow.

"Damn, this guy's shell is almost the same as a steel-hull mutant!" Hong Yi knew that he had encountered a hard stubble, and the next moment, another spider silk sprayed over, Hong Yi hurriedly moved quickly to dodge, but the area of this passage was very small, and Hong Yi's speed was limited, so he could only barely dodge.

After that, Hong Yi suddenly felt that danger was coming, but he hurriedly dodged it, but saw that the spider mutant was extremely fast, and he actually pounced and slashed himself with his sharp insect limbs.

The spider mutant's several long blade-like legs flew up and down at this moment, and once it was stabbed, it would definitely be penetrated, and if it didn't die, it would definitely lose its combat effectiveness immediately.

This spider mutant obviously has the strength of the white star third-level mutant, and if he were someone else, he would have been put down a long time ago, that is, Hong Yi's strength is outstanding, although he is not good at close combat, but he has the skills to deal with this situation.

"Fireball, kill!"

Hong Yi quickly used the Fireball Ring to condense a fireball and smashed it out, the spider mutant obviously didn't expect it, it was directly smashed into a solid, and the fireball turned into a ball of flames, burning it squeaky and screaming.

The spider mutant, though with a bulletproof shell, was afraid of flames, and was instantly charred and blackened, and immediately fled, burrowing into the hole it had previously built, and the flames set some of the surrounding webs on fire. Although these cobwebs are extremely tough, they are also afraid of flames, seeing this, Hong Yi immediately had an idea, and once again condensed a fireball, smashing directly towards the passage in front of which was sealed by layers of cobwebs.

Rumble!

The flames had an unexpected effect, and the spider silks that were tough enough to resist the alloy machetes and had a corrosive effect were broken and burned under the flames at this moment, and in a short time, the passage was burned open a gap, enough for Hong Yi to enter.

Ignoring the surrounding flames, Hong Yi walked in quickly, passing through the layers of cobwebs that were four or five meters long, and arrived at the inner cave.

After entering, Hong Yi found that there was a cave inside.

First of all, the cave below is very large, almost like an underground world, and the height of the cave alone is more than twenty meters. Hong Yi looked around and saw a lot of corpses of spider mutants, of course, the size of these spider mutants was not as huge as the one that attacked him just now, but it was not small, the smallest one was the size of a basin, and so many spiders made people goosebumps.

There are also many types of spider mutants here, and even through the variant database of Adjutant Zhi's brain, Hong Yi can only barely recognize a few.

There are 'defenders' with hard shells, 'marauders' who can spray venom, and spider mutants with unknown information.

Some of these mutants have been gouged out of their brains, while others have not.

Hong Yi walked forward for a while, felt a movement on his side, and immediately shot an arrow with a bow, an alloy arrow like lightning shot a 'marauder' who was about to sneak attack and spew venom seven or eight meters away.

"Kill the Spider Mutant and get 1 XP!"

Hong Yi looked at his experience points, as long as he came to 19 points more, he could raise the 'Shadow Walker' to level 1 and obtain a skill.

Entering the spider's lair this time, Hong Yi himself didn't know what he would encounter, after all, even Wu Tong, a mentor-level evolutionary, was trapped and couldn't get out, and the giant spider mutant who had reached the third level of the white star just now, this monster was obviously very good at sneak attacks, and it was very difficult to escape when it encountered an attack. So for Hong Yi, the more hole cards he can get, the more beneficial it is for him.

After walking through here for a while, there were already seven or eight spider mutants attacking, but all of them were shot by Hong Yi one by one, and the arrows used were all ordinary alloy arrows.

This time, Hong Yi only brought a quiver's energy arrow, who would have thought that an ordinary training course would encounter this kind of accident, it can be said that Hong Yi's preparation was very inadequate, and even the location of the smoke fart at the moment was more than seventy kilometers away from here, so Hong Yi did not summon the smoke fart over.

A large area of corroded spider silk appeared in front of it, splitting the entire cave in half, and the amount of spider silk here is simply outrageous, saying that it is spider silk, but in fact it is a wall that was once difficult to break through.

And in this huge spider web, Hong Yi saw a huge spider mutant lying on it, and many compound eyes were staring at him at the moment.

"It's that guy just now!" Hong Yi saw that the giant spider mutant was scorched black, and immediately recognized that this was the mutant that had attacked him before.

When it saw Hong Yi coming, it immediately let out a few screams, the sound was very harsh, like someone pricking your eardrum with a needle, which was unbearable.

Hong Yi was not polite, endured the stinging pain of his eardrums, took out an energy arrow and poured fire energy, and shot it out with a bow.

The spider mutant obviously knew that it was powerful, and hurriedly dodged, but its speed was still a step slower, and the arrow was extremely fast, directly piercing its back, and the blazing fire energy could be injected through the wound, and it only took a moment to scorch the internal organs of the spider mutant.

The spider mutant let out an unprecedented scream, almost half of its body was scorched, but it was hard to believe that it was still alive, and instead of being killed by the arrow, it quickly climbed and escaped through a hole in the top.

Hong Yi shook his head, he didn't expect that the vitality of this spider was so tenacious, and it would have been burned to death if it were replaced by other mutants.

However, this arrow is enough to make the opponent lose half a life, at least for a short time, this elusive spider mutant is unlikely to come back to sneak attack. And Hong Yi hit a 'hunter marker' on the other party before the other party fled, so that Hong Yi already knew the other party's location, which means that if this mutant came to play sneak attack again, Hong Yi was sure to shoot it as soon as possible.

Putting away the longbow, Hong Yi condensed a fireball to open the way, boiling a passage for the corrosive spider silk blocking in front of him, and slowly moving forward.

These spider silks blocking the passage obviously appeared in the last few hours, otherwise Wu Tong and they would not have been able to pass through here before, maybe it was because after entering here, they found that the retreat was blocked and they could not leave, so they were trapped here.

Looking at the top cave where the spider had escaped, Hong Yi shook his head, at this height, only spiders can climb up, and it is impossible to use these corroded spider silks unless he dies.

After condensing a full three fireballs, Hong Yi opened a channel, but the continuous release of fireballs also consumes a lot of Hong Yi's biological energy, and if it is not necessary, Hong Yi will not use biological fire energy again.

Along the way, Hong Yi did not find any fresh human corpses, you must know that counting the previous group of students, there are at least thirteen human beings who have entered here, including Wu Tong, Li Ming and Song Hui.

However, Hong Yi did not find the bodies, which means that these people may still be alive.

There is almost no outside light here, only some inexplicable stones and plants emit extremely weak biological light, Hong Yi has long controlled the adjutant Zhi's brain to switch to night vision, but even so, the visibility of the field of vision is also greatly limited, at most you can only see the scene more than ten meters away, and no matter how far away, it is pitch black.

In this environment, if you don't have an adjutant brain, it is absolutely impossible to rely on only the five senses of human beings.

Several spider mutants hidden in the darkness waited for an opportunity to ambush Hong Yi, but they were all shot by Hong Yi from a long distance, it can be said that as long as it is a mutant that enters Hong Yi's field of vision, Hong Yi will be shot and killed.

The benefits of this are twofold, one is to eliminate the danger, and the other is to gain experience.

Finally, after shooting out a spider mutant, Hong Yi accumulated enough experience points to immediately upgrade the 'Shadowwalker' skill tree.

"Shadow Walker to level 1."

"Bone strength is increased by 1 point, muscle strength is increased by 1 point, and agility is increased by 1 point."

"To unlock the skill 'White Blade Assassination', the next level requires 200 experience points."

Hong Yi felt that a large amount of data flowed into his brain, including how to use the skill 'White Blade Assassination'. Undoubtedly, this is the melee skill that Hong Yi lacks the most now.

White-bladed assassination, to put it bluntly, is a short-weapon combat method that includes a variety of stabbing attacks, and the weapon suitable for this skill is undoubtedly a weapon such as a dagger.

Pulling out the alloy dagger on his waist and holding it in his hand, Hong Yi felt completely different from the feeling of holding the dagger before.

Very familiar, Hong Yi's fingers moved, the dagger turned in a circle in his hand, and then held it steadily, and the backhand and forehand can be changed very skillfully, as if after a long time of practice.

You won't fall off your hand, and you won't hurt yourself.

At this moment, in the darkness, a spider mutant slowly approached Hong Yi, a defender spider with a hard shell, fast speed, and good at flying and biting. At this moment, it slowly climbed to a range of four or five meters away from Hong Yi, and suddenly accelerated and flew up, with its speed and strength, it was enough to knock an ordinary person down, and at the same time bite the skin and bones of a human with its sharp mouthparts.

Especially in the darkness, there was little anyone able to dodge their attacks, but in a surprising sight, the swift defender spider pounced in the air, and almost at the same time, a sharp alloy dagger stabbed down from behind, straight into its back.
