Yun Lan's strength could only match that of a mid-fourth-order demon beast, but she had fought against the Iron Eater Spider before, so she knew where the opponent's weakness was. With the flexible divine step, it is not impossible to fight a war.

The armor on the iron-eating spider's body is extremely hard, but it can only cover the head, chest, and legs, and the defense of its belly is far from comparable to the armor of these parts.

When their strength was low, they relied on the Heavenly Thunder to break the defense of the female iron-eating spider, and now Yun Lan can do it herself.

After the spider silk, the iron-eating spider inside popped out after it, Yun Lan took a few steps back, distanced herself from the other party, and the ice wall in front of her was also instantly shattered by the iron-eating spider.

At first, the spider silk was just a tentative attack, but now it's the real thing.

Yun Lan hadn't forgotten how strong the spider silk that threw her into the depths of the secret realm was in the first place, and it was still a near-death blow from the female iron-eating spider.

The strength of this male iron-eating spider is stronger than that of the female iron-eating spider, and it is in its heyday, and the power of the spider silk cannot be worse than that of the female iron-eating spider, which can be seen from the ice wall that it easily shattered.

The weakness of iron-eating spiders is in the abdomen and head.

The male iron-eating spider is small, and it is not only difficult to hit the head, but it is giving the other person a chance.

Whether it is the front paws or the mouthparts, it can protect its head to death, so Yun Lan must give priority to the abdomen.

Although the newly arrived mace was a high-grade spatial type magic weapon, it was difficult to cause damage to the elastic abdomen of the iron-eating spider, so Yun Lan chose the dragon rhino horn.

It's a little bigger, but the corners are very sharp.

Yun Lan only needed to cut the belly of the iron-eating spider, and then slowly delayed the time, no matter how she could boil it to death.

Using dragon rhino horns as weapons was still the inspiration she had gained from previous mining, when the ice axe she used to condense with spiritual power could not cause any damage to the land in Mojiao's lair, but with dragon rhino horns, she could easily dig out the spirit stones inside.

When her strength is enough in the future, she will refine this dragon rhino horn into a magic weapon, and its power will definitely be good.

Now, with her cultivation, it is still too eye-catching to take out such a treasure.

Even if there was a refining master who could refine dragon rhino horns, Yun Lan didn't dare to gamble with his own safety.

She inexplicably had a lot of knowledge about refining weapons in her mind, as long as she was given time to practice, refining a high-grade magic weapon shouldn't be a problem.

The dragon rhino horn was large and heavy, and it was naturally impossible for Yun Lan to hold it up to fight a human-tall spider.

The Hail Technique started, reducing the speed of the Iron-eating Spider, and then using the Divine Walk to move behind it, the huge dragon rhino horn appeared in Yun Lan's hand, stabbing at the Iron-eating Spider fiercely.

The iron-eating spider obviously didn't expect Yun Lan to have such a strange method, obviously it was still in front of it one second, and disappeared the next second and appeared behind it, and it didn't react for a while, and was directly pierced into the ground by the dragon rhino horn.

The fat belly of the iron-eating spider was directly pierced by the dragon rhino horn, and the yellow liquid of feces flowed out, and it was strange that the iron-eating spider was so badly injured that it lay there motionless.

Yun Lan didn't dare to approach, and some demon beasts would use pretending to be dead to paralyze the enemy's vigilance and make them ignore their precautions.

And just by attacking the stomach to kill it?

When pigs fly.

The female iron-eating spider had already confirmed this, dragging her belly with a big hole in her belly and fighting them for a long time, and she did not fall behind in one dozen or five.

The ice spear appeared in Yun Lan's hand and was thrown far away by her.

The ice spear collided with the armor on the iron-eating spider's body, making a crisp sound, and bounced to the side, but the iron-eating spider remained motionless.

Yun Lan observed carefully, the eight eyes of the male iron-eating spider were tightly closed, and the whole body was also prostrate on the ground, but its belly, which was pierced by the dragon rhino horn, was still rising and falling.

Didn't die.

When she saw the jade-colored dragon rhino horn again, Yun Lan's mind had a thought: wouldn't it be because she was shocked by the aura of the 10,000-year-old dragon rhino on the dragon rhino horn, so she didn't dare to resist, right?

Low-level demon beasts will also attack when they encounter strong human cultivators, but there is a strict hierarchy between demon beasts, unless they are sure to kill each other, low-level demon beasts will never dare to provoke the existence of high-level demon beasts.

Just like the two sixth-order demon beasts that had friction in the forest before, just that little movement brought an overwhelming beast tide to the monks who entered the Relic Mansion.

Yun Lan tentatively took a few steps forward, and could clearly see the iron-eating spider's eyes moving under her nose, but she still didn't dare to open them.

The dragon rhino that can live for tens of thousands of years, it is an eighth-order demon beast, and its slightest breath is enough to make a fourth-order demon beast bow down.

Of course, this does not mean that Yun Lan can run rampant in the Relic Mansion.

This aura can only deter some low-level demon beasts that have not opened their spiritual intelligence, once it encounters a demon beast that has given birth to spiritual intelligence, it can clearly know that this is just the breath left by that powerful existence, and there is no threat to it at all.

If nothing else, it was enough to deal with the ink Jiao and the white-haired monkey at the beginning, but it was enough to deal with the fourth-order demon beast of the insect class.

Bugs are obviously much less intelligent than animals.

Yun Lan thrust in with an ice spear from the gap between the Iron Eater's head and chest, and the Iron Eater's body twitched violently, as if it wanted to resist, but it was too late.

There is the key point, and piercing that place is equivalent to cutting off a person's cervical vertebrae, and it can kill you on the spot.

It was only when the iron-eating spider's vitality completely dissipated that Yun Lan began to collect the materials on its body.

Huang Xinyue and the others gave her what they thought was better, but Yun Lan wanted the soft skin of the spider's abdomen more, as well as the mucus in the belly that could produce spider silk, which was an excellent material for making talismans.

The previous lizard skin was given to Lan Hong by Yun Lan, and now another iron-eating spider has come to make up for her lost material.

The blood of the iron-eating spider was of little use, and it looked disgusting, so Yun Lan didn't collect it, but just took off the armor and legs from other places.

He used his spiritual power to absorb the dead branches around him, and set the remnants of the spider corpse on top of it, burning it to the ground.

It was indeed much more convenient for the Fire Attribute Spirit Root Cultivator than other Spirit Root Cultivators when they went out to practice, but Yun Lan now had Vermilion Bird Feather, which brought her a lot of convenience.

If possible, she wanted to find a spiritual fire to sign a contract with her, so that she could not rely on earth fire for alchemy and refining.

But that's just thinking about it, spiritual fire is extremely rare, and the monks who have spiritual fire in the entire cultivation world can count it on one hand.

Yun Lan couldn't help but think of the round stone flowing with magma in the storage ring, which was the egg of a fire-attribute demon beast.

If there is no spiritual fire, it is not impossible to contract a fire-attribute spirit beast.

But in this case, she would not be able to control the flames as she wanted, and the elixirs and magic weapons she refined would be greatly reduced.

After processing the surrounding battle traces, Yun Lan walked towards the hole where the iron-eating spider came out.

Although the iron-eating spider is a social monster, it often only has one powerful female spider.

The iron-eating spiders that Yun Lan encountered were an exception, the male spiders were still alive, but there were only these two, and even if there were, they were some small spiders that didn't pose much of a threat.

At the beginning, they were all able to clean up the small spiders under the threat of the big spiders, and now Yun Lan is even less likely to be afraid of them.

The divine consciousness went directly down the passage and went deeper, without the slightest movement, and the female spider was afraid that she had taken all the young spiders out to forage for food.

This passage was just big enough for the male iron-eating spider to pass through, and for Yun Lan, it was a spacious passage.

However, this passage was extremely deep, she took out a spirit stone to illuminate it, and before she went far, small white spots appeared on the inner wall of the passage.

The sound of footsteps echoed in the passage, from one to two, and from two to four, and it didn't take long for it to become countless footsteps around Yun Lan, as if surrounded by many people, and his head began to dizzy.

This is the sound stone mine.
