Zhang Yu had just gotten up from the magma, and the junction between the magma and the land around him was full of dark red fine and soft sand grains, if you pinch it with your hands, it is still gentle and soft.

This is the main specialty of the Fire Vein Spirit Cave - Yan Shen Sha, the dark red color of Yan Shen Sha that has not changed color for a hundred years seems to be red-hot charcoal, and it is a very popular building material in the cultivation world, whether it is an alchemy room or a refining room, or the main material of the cultivation meditation room of the Fire Spirit Root Monk.

Of course, if there are some loose cultivators or relatively poor small sects and small families, this may also be the main raw material for magic weapons.

Zhang Yu didn't have the heart to feel like he was facing the herring fish fantasy "herring series" magic weapon, and the experience of the past few days told Chang Yu that a thousand birds in the forest are not as good as a bird in hand.

While carefully sacrificing the ten-mile copper mountain umbrella, Zhang Yu looked at this spiritual cave, just as there are many lakes in the rivers to store water, the fire vein is also a lot of spiritual cave "water", the harvest year here can accumulate excess aura, and the aura here in the owe year feeds the entire fire vein.

This spirit cave is the size of a football field, and there are some spirit plants in the distance - it is a good thing to be able to survive in the fire vein spirit cave!

Zhang Yu's greedy eyes glanced around, there were demon beasts in the fire vein magma, how could there be no here?

Pregnant!

The demon beasts in the fire vein rarely encounter monks, and the demon beast hiding techniques here are mainly aimed at the existence of fellow demon beasts, and Changyu soon discovered the biggest predator in this football field:

A red crocodile with seven long spikes on its back was inconspicuous in the magma, but it was unusually noticeable in this dark red spirit cave.

Iron Back Stabbing Flame Crocodile!

Although it is not comparable to the strength of the foundation building period, it can be regarded as a demon beast in the late stage of qi cultivation at most, but if it is tough and strong, the foundation building monk will also have to weigh it, and if it is the older iron back stabbing flame crocodile, I am afraid that even the foundation building monk will have to capsize in the gutter.

The eyes of the iron-backed stabbing flame crocodile were also staring at Zhang Yu, an uninvited guest, but he didn't make a move in advance, a monk like Zhang Yu was indeed a rare elixir in the eyes of ordinary demon beasts, but in the eyes of pure attribute demon beasts such as fire veins, there were some chicken ribs.

A variety of spiritual root attributes appear redundant, and some of them are tasteless, but a body of spiritual energy is also quite a greedy demon beast, and it is a pity to abandon it.

When the iron-backed stabbing crocodile did not make up his mind, Zhang Yu made up his mind to do it, it was difficult to find the spiritual acupoint in the fire vein, and if he continued to find it, Zhang Yu's plan would be delayed!

Zhang Yu jumped up and stayed in the air above the spirit cave, these rock walls were quite strong by then, but unfortunately the space was too low, and it was easy for the iron back stabbing flame crocodile to fight back.

Can't go this way!

Zhang Yu's mind turned around and finally decided: he can only attack hard!

The demon beasts in the fire vein magma rarely appear in the empty spirit cave, and Zhang Yu has been out of the Chacha Mountain Sect for so many days, either hiding in the protective shield of the formation, or running away directly, and it is time to be tough and tough.

Although the Iron Back Stabbing Flame Crocodile is strong, it is not completely impossible to deal with!

Zhang Yu cheered himself up to the north, while directing the copper nail to stab the eye of the iron crocodile at the iron back.

The iron-backed stabbing crocodile is covered with scales and armor all over its body, and there is a weakness in its eyes on the front, how can it be easy for Zhang Yu to succeed?

As soon as the two transparent eyelids of the iron back stabbing crocodile were closed, the attack of the copper nail was bounced away, and if you were quiet and listened, you should still be able to hear the sound of gold and iron colliding between the two!

The Iron Back Stabbing Flame Crocodile did not take the initiative to attack Zhang Yu because he was worried about the possibility of being injured by the attack, but seeing that Zhang Yu, the little guy, took the initiative to attack, he definitely had no intention of shrinking his head turtle.

Seeing the Iron Back Thorn Flame Crocodile rushing towards him, Zhang Yu was not panicked, while directing thirty-six copper nails to continuously hit the Iron Back Thorn Flame Crocodile, angering the Iron Back Thorn Flame Crocodile, Zhang Yu rushed towards a mound behind him.

It is said to be a mound, but this is actually a ridge with a person to climb up and down the slope, and when Zhang Yu desperately escaped and crossed this slope, the iron back stabbing flame crocodile stopped

Although the iron back stabbing flame crocodile has lived in the fire vein all his life, he is not stupid, although he can only scratch the itch remotely and indifferently when he sees Changyu, but there is no shortage of vigilance, although the iron back stabbing flame crocodile has an iron back, but the abdomen is unusually soft.

However, the figure of the Iron Back Thorn Flame Crocodile stopped for a moment, but it was angry by the thirty-six copper nails on his body that kept clanging, plus Zhang Yu had never been to that mound in the spirit cave along the way, and the Iron Back Thorn Flame Crocodile rushed forward with a fluke mentality!

Zhang Yu saw the Iron Back Stabbing Flame Crocodile approaching and retreated unhurriedly, but the safe distance must be guaranteed, the seven spikes on the Iron Back Thorn Flame Crocodile are not good-looking, if it is really close to the Iron Back Thorn Flame Crocodile, it will use the spikes to attack the weakness of the prey while attacking the target, that is, when dealing with some small prey, the Iron Back Thorn Flame Crocodile itself does not move, just rely on the spikes.

The iron-backed stabbing crocodile came to the mound and looked again, and after confirming that there was no Zhang Yu's secret hand here, he boldly stretched out his two front paws and climbed up.

But the mutation appeared at this moment! The fire ruler rushed out of those glamorous sands, and directly hit it, and forcibly turned the iron back stabbing flame crocodile over!

Zhang Yu was waiting for this moment, as early as he had just ascended the spirit cave and buried the Huojiao ruler in the Yanshen sand, and he thought of countermeasures in his first reaction when he saw the iron-backed stabbing Yan crocodile, but it was too far away from the mound at that time to command the Huojiao ruler to move so far in the Yanshen sand.

Therefore, Zhang Yu simply took a light risk and jumped onto the rock wall not only to check the situation of the rock wall, but also to gradually command the fire ruler to move to the mound.

The fire ruler is not a soil escape, and it stands to reason that the Iron Back Thorn Flame Crocodile will definitely find it, but with the obvious goal of Changyu, how can the Iron Back Thorn Flame Crocodile have time to find out?

Seeing that it was difficult to get up for a while when the iron back stabbed crocodile was facing the sky, and even the seven spikes on his back were useless, Zhang Yu naturally took advantage of his illness to kill him.

While pressing the abdomen of the Iron Back Thorn Flame Crocodile with a fire ruler to prevent him from turning over, Zhang Yu commanded thirty-six copper nails to nail down into the soft abdomen of the Iron Back Thorn Flame Crocodile!

The iron-backed stabbing crocodile is not a vegetarian, the softness of the abdomen is only equivalent to the iron back, and many of the thirty-six copper nails are bounced off after a burst of gold and iron impact, but there are many of them, and there are always a few copper nails directly into the abdomen of the iron-backed stabbing crocodile!

To say that it is usually quite easy for the Iron Back Thorn Flame Crocodile to turn over, but at this time, it was suppressed by the Fire Jiao Ruler, but the reaction of the Iron Back Thorn Flame Crocodile was not too fierce without obvious damage, until the copper nail entered the abdomen, and the Iron Back Thorn Flame Crocodile made a terrible cry followed by a fierce tremor, that is, Zhang Yu strongly supported the Fire Jiao Ruler or let the Iron Back Stab Flame Crocodile turn over!
