"[Fighting Qi Explosion]!" Xia Chengfeng used the Fighting Qi to shake all these attacks away. He landed on the ground and killed two ordinary monsters.

[Steel Slime LV33]: Slime that absorbs steel growth and is proficient in metallic element attacks.

These steel slimes look like a toad covered with rust, and they are constantly spitting out metal bullets, spikes and other things to attack them.

Jingjing also fell down, and the steel slime attacked it, but because her body was made of magic crystals, this attack could not hurt her at all.

"So cute!" Jingjing hugged a steel slime and said in surprise.

"Cute?" Xia Chengfeng looked puzzled. Can this thing be called cute? It's obviously ugly and frustrated!

"It can still scratch it!" Jingjing said seriously.

However, what Xia Chengfeng saw was indeed the steel slime attacking her desperately. Her biting behavior was understood as tickling...

"Just be happy." Xia Chengfeng was speechless. He quickly used several skills to clean up the surrounding [steel slime].

Jingjing was still holding one in her arms. The steel slime had exhausted its golden element energy and was rolling her eyes and twisted it into her hand.

Decompose [Slime Steel] to obtain materials such as [Gold Element Crystal], [Slime Bullet] or [Slime Iron].

Xia Chengfeng looked around and found no treasures, so he prepared to descend to a deeper mine again.

This time it fell another thirty-five meters, and a second mine appeared.

Similarly, there are still a bunch of [Steel Slimes] attacking them, and there are several [mutated Steel Slimes LV34 (elite)].

In addition to physical attacks, hardened steel slimes will also use sound-based magic attacks, [Metal Noise].

This skill will keep echoing in your ears, making you irritated and causing mental damage.

"Aowu!" Xiao Zi was also tired of their noise, and with the dragon's [Battle Cry], he calmed the slimes!

Xia Chengfeng cleared it with a [Blowing Fire Palm].

Jingjing didn't even have a chance to take action. The "cute" steel slime just now was almost killed by her, and she changed to a larger mutated steel slime.

The third drop, the mine became deeper and wider, and the depth of the drop was deeper.

While Xia Chengfeng was still descending, Jingjing suddenly jumped out of the earth escape and slashed behind Xia Chengfeng with a sword.

Blood splattered on the mine wall, and a figure roared into the mine wall.

"Master, be careful, there are monsters who want to sneak attack you!" Jingjing tightened her magic sword.

Xia Chengfeng also sensed the monster, [Iron Eating Worm LV35 (Lord)]: A monster that uses iron ore as its food also likes to swallow flesh and blood.

"There are more than one iron-eating worm!" Xia Chengfeng also escaped into the wall. During the descent, he had no focus on his feet and it was difficult to exert his strength.

Another iron-eating worm attacked him. Its body was covered with rust, reddish-brown, and looked like an earthworm, but much larger than an earthworm. Its body length was probably more than ten meters long. Its head was a big mouth comparable to a wellhead. It seemed that there were tens of thousands of teeth embedded in it. Even hard metal, it could eat crispy!

Iron-eating insects can help you escape the soil and can also launch attacks in the soil.

Xia Chengfeng escaped from the soil, and with a backhand, he instantly beat his head into mud. But it still did not die, and its remaining body sneaked into the soil and escaped.

"Is it really a mutated earthworm? You can survive by tying it into two pieces?" Xia Chengfeng thought to himself.

"This little bug is so cute too! I really want to raise one!" Jingjing exclaimed, her pretty face full of pampering.

Xia Chengfeng: “…”

He thought to himself that Jingjing himself might be a rock-like magical life, so he naturally has a good impression of this underground creature!

Xia Chengfeng descended to the third mine cave, where a bunch of mutated steel slimes and several iron-eating bugs were already waiting for him.

"【Rock Clan】!" Xia Chengfeng first used his clone to avoid sneak attacks, and then used fighting skills to attack.

The space in the cave is too small, and using flames to post books can easily affect yourself.

Due to insufficient oxygen, Xia Chengfeng's recovery ability has also decreased, and he must preserve energy as much as possible.

Xiao Zi also used skills such as [Tearing Claws] and [Raging Thunder]. Each of its claws carries lightning and has doubled damage to the steel slime!

The thunder attribute is to restrain metallicity!

"Jingjing, kill them!" Xia Chengfeng shouted.

"Received!" Jingjing was not showing any weakness when fighting. She held a sword in both hands, and the flame element energy in her left hand and the ice element energy in her right hand could be converted at any time.

In this underground mine, ice-attribute energy is better used.

Wherever her magic sword slashed, all the monsters were frozen into ice, but turned into pieces on the ground.

"[Fighting Skills - Black Lion Seal]!" Xia Chengfeng cast a Dou Qi mark into the mouth of an iron-eating worm. The mark stretched out along its intestines, opening its head and tail, turning it into a layer of insect skin.

The system prompts: "You have killed [Iron Eater LV35 (Lord)] and gained 20,000 points of combat experience."

"If you fight like this, you can't split up!" Xia Chengfeng found the trick and wanted to attack while the iron-eating worm opened his mouth.

He used this trick to kill another iron-eating worm.

Looking back, Xiao Zi and Jingjing had killed four iron-eating insects, and they had even upgraded to one level.

"It's great to restrain attributes!" Xia Chengfeng was a little envious of them. His fire element skills were to restrain the gold element, but it was difficult to use them here.

He glanced at the cave and found that the space here was spacious than before, and there were also many more monsters. He could feel that there were monsters hiding in the rock walls.

"Fighting skills--" When Xia Chengfeng was about to attack an iron-eating worm, the ore on the soles of his feet suddenly disappeared, and a big mouth bit his body.

This guy was hiding very deeply, and Xia Chengfeng didn't even notice its existence. At this time, it was too late to use the rock clone.

"【Fly】!" He activated the alchemy backpack skill, rushed to the top of the cave, and then used earth escape to enter the rock.

The monster hit the top of the cave and chewed on a mouthful of gravel.

[Iron Armored Beast LV36 (Baron Lord)]: Monsters living in mining areas can devour metal elements and grow.

The appearance of the iron-armored beast is a bit similar to that of a crocodile, and it is also a little like a pangolin. Its skin is extremely hard and is completely made of fine iron. Ordinary weapons cannot harm it, and it can easily break rocks and metals.

"[Fighting Skills - God Palm from Heaven]!" Xia Chengfeng fell from the top of the cave and slapped it with a palm.

The iron-armored beast crawled into the ground again, and Xia Chengfeng was in vain.

"These earth attributes and metal monsters are really annoying!" Every time Xia Chengfeng wants to attack them, they will quickly dodge them.

And Xia Chengfeng himself could not attack while escaping in the earth or iron ore.

"Master, I'll help you!" Seeing this, Jingjing inserted Fick's magic sword into the ground and activated the passive skill of the magic sword - [Sealing Sword Formation].

The seal runes merged into the underground and surrounding walls, and the surrounding space was blocked by the seal runes. Three iron-eating insects and two iron-armored beasts "bounced out".

"Good!" Xia Chengfeng praised and simultaneously used a [Ground Hardening] skill, so that these monsters would not break the seal rune in a short period of time and would return to the rock again.

"Tear~" Xiao Zi's claws sparked with lightning. The iron-eating worm that exposed her true body could not withstand its attack at all, and was immediately torn apart.

Moreover, the iron-eating worm that was electrocuted by it also lost the ability to regenerate the residual limbs.

“【Must-arm strengthening】!”

"【Lion King Fist】!" Xia Chengfeng punched a sudden punch, hitting the body of the iron-armored beast, and the fist print directly smashed its body into a big hole.

"I said your body is as hard as the Diamond Rock giant, so that's it!" Xia Chengfeng got rid of one end, and the second end was much easier to fight.

The second armored beast was already aware of the danger and was ready to escape. It hit the rock wall violently. The earth's hardening and sealing effects were shaken apart.

"【Vine strangle】!" Xia Chengfeng tied it with his vines.

"【Crystal Barrier】!" Jingjing was also helping, and a crystal barrier blocked the iron-armored beast's escape route.

"Die!" Xia Chengfeng ended its life with the Vajra Claws. He pierced his head and kept his body intact.

System prompts: "You have killed [Iron Armored Beast LV36 (Baron Lord)] X2 and gained 800,000 points of combat experience."

“Your level has been upgraded to LV35.”

Xiao Zi dealt with two other iron-eating insects and the battle ended.

Xia Chengfeng ate a pill of [Qi Replenishing Pill LV29] to replenish Dou Qi. Xiao Zi directly roasted an iron worm-eating body, swallowed its meat, and used the [Glut Eater] skill to replenish energy and physical strength.

Only Jingjing, who fought for a long time, seemed to be completely useless and seemed to have no consumption at all.

When underground, she can quickly replenish her energy.

Xia Chengfeng began to decompose the corpses of these monsters. When he was about to decompose the iron-eating worms, he was stopped by Xiao Zi.

"Ao~" it screamed a few times.

"You mean its meat is delicious? Let me not break it down and leave it for you?" Xia Chengfeng asked.

"Ao!" Xiao Zi nodded.

"Okay." Xia Chengfeng put away the corpse of the iron-eating worm and picked up a few [Suce Iron Rune Key].

The corpses of the two armored beasts were broken down in one breath.

System prompts: "Successfully decomposed, we will obtain [Energy Crystal LV36] X2, [Gold Element Crystal LV36] X2, [Soul Stone LV36] X2, [Iron Eater Iron Armor LV36] X2, [Iron Eater Iron Eater Teeth LV36] X2, [Iron Eater Tail Whip LV36] X2, [Iron Eater Iron Eater Skeleton LV36] X2, [Bronze Rune Key] X2."

Xia Chengfeng walked around the cave and found six treasure chests, four of which were [Pure Iron Rune Chest] and two [Bronze Rune Chest].

In the fine iron rune treasure chest, there are some magic crystal coins and metal materials, which Xia Chengfeng put away directly.

Two [Bronze Rune Chests] were opened together by him.

"Magic crystal coin X200,000."
