After going down for about ten miles, I entered a cave, which was extremely winding and not wide.

The highest height is only a few tens of zhang, and the width is only more than ten zhang, and it is dark inside, if it weren't for Duan Tian's strong divine sense, I'm afraid I wouldn't see anything.

Here, Duan Tian can only sense a range of tens of miles, which is far closer than the sensing distance on the ground.

This is just sensing the open space, if it is hiding under the ground, if it is in the cave wall, it is difficult for Duan Tian to sense too far.

Put away Duan Sanpang and release Tie Er's companion. Qi Yunbao was injured before, and he was not well, so he couldn't help for a while.

This hole is even more unsuitable for releasing black gold, and even if it is released, it will not be able to play at all.

Duan Tian is in front, Tie Er is behind, carefully exploring all the way. There are countless branches of the underground demon clan, and Duan Tian doesn't know what kind of demonic beasts are active here.

It didn't take long to feel an iron-backed reptile crawling over, this iron-backed reptile was not big, but it was more than a foot long, and it crawled very fast in the hole, and it was four-legged and slashed, and it arrived in an instant.

Tetsuji roared and walked away against the crawler. With both fists like the wind, he brought up a huge fist shadow and smashed it at the iron-backed reptile, which held its head high and slammed it with its ugly head.

Tie Er's giant fist hit the head of the iron-backed reptile, like hitting a hard metal plate, making a huge sound of gold and iron.

Tie Er screamed miserably, and was hit by the ironback reptile and flew backwards, his body was blocked by the cave wall, so he didn't retreat too far, but a large piece of gravel fell from the cave wall behind the impact, obviously this impact force was not small.

Tie Er roared again, and his fists hit the ironback crawler continuously, fighting with the ironback crawler.

Duan Tian also stood aside to watch first, to see what this iron-backed reptile was capable of. This iron-backed reptile has an extremely simple way of fighting, that is, it supports the ground on all fours, and its head slams forward, although it is simple, but with its tenacious body, it actually forces Tie Er to retreat step by step.

The sound of gold and iron roaring continued to emit out, shaking the ground and trembling, after more than a hundred consecutive blows, Tie Er could no longer hold on, his fists hung down softly from his wrists, and even his wrists were broken.

Duan Tian took Tie Er back to the foundation of creation to recuperate from his injuries, and immediately turned into a dragon and grabbed the iron-backed reptile that continued to collide.

I was secretly shocked that this iron-backed reptile was really powerful, and it actually broke Tie Er's wrist.

As soon as the huge dragon claw came into contact with the iron-backed crawler, he felt a huge momentum, Duan Tian was hit by this momentum, and he even took a few steps back to stop his body, Duan Tian's dragon claw was also knocked away by the iron-backed crawler, and he couldn't catch it at all.

Duan Tianlong's claws turned into fists, and he punched the iron-backed reptile on the head with all his might, and finally rolled the iron-backed reptile backwards, but Duan Tian himself was forced to retreat a few steps.

Seeing that the dragon claws couldn't take advantage, Duan Tian immediately sacrificed his flying sword, and in the darkness, a dazzling red light slashed at the iron-backed reptile, and at the same time, Chongji Ding also slammed into the iron-backed reptile with a huge momentum.

The iron-backed reptile is really hard, and it will not fall behind under the impact of the heavy pole, and the huge counterattack power also consumes a lot of spiritual power from Duan Tian.

Duan Tian knew that this iron-backed reptile had almost no weaknesses, his whole body was wrapped in iron sheets, and his abdomen was also extremely tightly defended, so he had no chance at all.

It's really hard to win with a hard fight, and in this case, the only way to kill the iron-backed reptile is to rely on the sharpness of the flying sword.

Taking back the Heavy Pole Ding, Duan Tian wholeheartedly controlled the flying sword to slash the iron-backed reptiles, the more difficult the situation, the more he greatly improved the flying sword swordsmanship.

Duan Tian's heart was like stopping water, and the Sky Piercing Sword continued to attack the iron-backed reptile with a strange flight trajectory, and Duan Tian's spiritual power after the dragon transformation was even stronger, and the power of the flying sword was also improved.

After more than 100 blows, he finally split several cracks on the back of the iron-backed crawler, and the iron-backed crawler saw that Duan Tian was powerful, but he turned around and drilled, and then escaped into the ground, leaving only a soil spiral nest on the ground.

Duan Tian spent countless strength, naturally refusing to let the iron-backed reptile slip away in vain, the spirit armor was completely inspired to protect himself, and he also drilled down the earth spiral, and when he fell, it was another cave, and the iron-backed reptile was running forward.

Duan Tian followed behind the iron-backed reptile and chased after him closely. The iron-backed reptile was extremely cunning, shuttling and changing in the cave, but it couldn't open up the distance from Duan Tian, it was always within the range of Duan Tian's divine sense, and it was gradually being chased closer.

The iron-backed reptile drilled down several layers of burrows in a row, and finally didn't dare to go down any further.

Duan Tian knew that this was already the most accessible place for iron-backed reptiles, and if he went down, it would be a higher-level place for demonic beast activities, and of course Duan Tian didn't dare to go down any further.

Forcing the iron-backed reptile in a corner, fighting fiercely for a long time, and finally killing the iron-backed reptile, Duan Tian is also tired, the fourth-level iron-backed reptile defense of this ground product is too strong, and the attack is also fierce.

If it weren't for Duan Tian's dragon armor protection, he would have been seriously injured if he had resisted several slammed hits of the iron-backed reptile before he died.

The cave is narrow, making it ideal for melee attacks such as the Ironback Crawler. The back armor of the ironback reptile is definitely a good material for refining the defensive spirit armor.

After putting away the corpse of the iron-backed crawler, Duan Tian didn't dare to stay here for a long time, and immediately found his way back to the first layer of the cave.

This underground cave covers an extremely large area, and Duan Tian was active on the first and second floors, encountering many underground demonic beasts along the way.

Some places in the cave are also extremely wide, and there are also places hundreds of miles wide, Duan Tian explored along the road, killed several fourth-level demonic beasts, and more than twenty third-level demonic beasts, and the harvest was extremely good.

In the battle with the fourth-level demonic beasts, Duan Tian's combat power naturally improved slightly, and he also had a lot of experience in dealing with demonic beasts.

In addition to iron-backed reptiles, there are also countless other monsters, such as iron-backed crawlers, bone crabs, blue-striped cockroaches, ink-black monsters and other reptile monsters, also called magic insects, and there are also magic snakes, magic frogs and many other beasts.

This is just an underground demonic beast, and it is said that there are also hideous and terrifying underground demons, collectively known as the underground demons. Where Duan Tian was now infiltrating, he didn't see the underground demons.

The underground demons generally have few flying demonic beasts, but if they do, they must be proficient in space escape techniques, they can be teleported, and the space in the cave is not limited at all, and they can exert greater power.

However, this kind of high-level flying demonic beast obviously resides in the depths of the earth, and it is not yet reachable by Duan Tian.

After hunting in the underground cave for about a few days, Duan Tian calculated the time, and there were still more than ten days before he went back, so he was ready to return to the surface to hunt some magical beasts again.

Duan Tian didn't know where this demon area was, but before he came out, he saw the Horned Demon Eleba Clan, and it could be roughly speculated that this area should be an area controlled by the Areba Clan, and the Terrans marked this area as the Areba region.

If the area controlled by the Aleba tribe has not changed much recently, there should be a vast area that spans more than 10,000 miles, which is much larger than that of Chuzhou.

The area controlled by the Aleba tribe is close to the west side of the Demon Domain, adjacent to the Terran area, and is separated by the Dark Moon Mountain Range, which is separated by thousands of miles of Dark Moon Mountain, and the Aleba are often the vanguard of the invasion of the Terrans.

However, as the Heavenly Demon Temple and other demon cultivation sects of the human race slowly expanded and became powerful in the Dark Moon Mountain Range region for tens of thousands of years, they also suppressed the Aleba clan.

There are about twenty or thirty million miles from the Blue Mist Sea of Chuzhou to the Aleba region, and if there is no space passage for such a long distance, the flight of the magic weapon alone will only take tens of thousands of miles a day according to the speed of Duan Tian, and it will take at least half a year to fly without sleep.

And there are no demonic beasts to stop them along the way, in fact, of course, it is absolutely impossible.

The Dark Moon Mountain Range is full of dangers, even the Great Cultivators of the late Yuan Infant Stage are in danger of falling, and wanting to pass through the Dark Moon Mountain Range is not something that Duan Tian can do now.

It's a complete coincidence that I entered the demon clan this time, and I don't know when I will come back in the future.

Therefore, Duan Tian also cherished this operation very much, not only to hunt the demonic beasts to the maximum, but also to add more understanding of the demons, regardless of whether they would come in the future or not.

Duan Tian found a place where there were few people, and once again hunted several fourth-level demonic beasts and one fifth-level early demonic beast.

The fifth-level early demonic beast was a troll barbarian bull, with a pair of huge curved horns on its head, which was able to release thunder and lightning, and it could also spew thunder and lightning from its mouth, coupled with the hard skin and bones, Duan Tian was also very difficult to fight.

There were other human races here, and Duan Tian naturally didn't dare to dragonize, but even if he was dragonized, Duan Tian estimated that he still couldn't win against this troll bull.

After spending a lot of spiritual power and divine sense, he had to ask the two dragons of gold and fire to take action and pierce the heart of the troll barbarian bull.

After putting away the corpse of the troll brute cow and recuperating for half a day, Duan Tian was ready to go to other places to shake it out.

Just as Duan Tian continued to fly, he suddenly heard a loud noise, Duan Tian turned his head to look, and saw the most spectacular scene in his life.
