"Roar ......" A huge dragon roar, Lin Lei felt that it was getting hotter and hotter behind him. He looked back and saw a huge fireball flying towards him. Lin Lei slashed with a sword, and the fireball exploded, and the scorching wave of qi dispersed. He jumped up and fell into the crypt.

"Boss, your head is burned!" Bei Bei entered the crypt with Lin Lei, and the dragons stopped in pursuit. After relaxing, Bei Bei couldn't help but laugh when she looked at Lin Lei.

Lin Lei grabbed his hair and looked at it, then looked at the sword in his hand, and couldn't help but smile bitterly. The fireball just now was so strong that it not only burned his sword, but also scorched his clothes and head.

"This sword is useless...... Lin Lei threw the sword aside, the sword body was already twisted, and it would break off with a little force.

"So it's cheap and not good, a sword with dozens of gold coins, can you still expect it to block an eighth-level demonic beast?" Zhou Tianci said, "When I have a body, I will personally build a sword for you!"

Drinkwater smiled, "Boy Zhou, have you ever been a blacksmith?"

"Except for the blacksmith, no one knows how to build weapons?" Zhou Tianci snorted lightly.

"Brother Zhou, will you go in now?" Lin Lei looked at the deep crypt, and if he took a step further, he would fall.

"Well, but be careful, this cave is seventy or eighty meters deep, and it's still some way from the artifact. Zhou Tianci said.

Lin Lei and Bei Bei jumped down together, and they fell to the ground not long after.

"Boss, what are we doing here?" Bei Bei was now in doubt.

"Find something!"

"What is it?" asked Bei Bei anxiously.

"I don't know, but it's ahead. ”

Lin Lei walked along the dimly lit path in the crypt, which was winding but wide. Lin Lei wondered why there was such a passage in the crypt that was more than ten meters wide and nearly ten meters high.

After groping in the dark for nearly half an hour, Lin Lei finally saw the light. Before he could speed up his pace, Zhou Tianci's voice sounded again.

"Lin Lei, be careful, there's a powerful ninth-level demonic beast in front of you!"

Lin Lei slowed down, touched the stone wall and walked forward cautiously, and at the same time told Bei Bei not to make a sound.

"Brother Zhou, can you deal with this ninth-level demonic beast?" Lin Lei asked in his heart.

"There should be no problem. "Before seeing the strength of the Warcraft, Zhou Tianci didn't dare to pack the ticket, he was able to exert the experience of the ninth level peak, but he couldn't last.

Lin Lei was relieved and came to the exit of the passage. He crouched down at the exit and looked in, and at the end of the passage was an underground cavern. The cave was very large, at least a few miles in circumference, and tens of meters high. In the center of the cave lay a demonic beast nearly ten meters long, and the demonic beast's whole body was covered with dark scale armor, and those scales were very tight, each piece was the size of a palm. On its back, the thirty-centimeter-long spikes are very terrifying, and those spikes extend from its forehead to the end of its back, which makes people feel chills when they look at it.

"The Backbone Iron Armor Dragon, the most terrifying dragon clan!" Lin Lei exclaimed in his heart, and the message of the Backbone Iron Armor Dragon appeared in his mind: Rank 9 Demonic Beast, dark attribute, the smallest dragon clan, the strongest defense and the most flexible among the dragon clans of the same level!

"It's actually a spineback iron-armored dragon!" Drinkwater's expression became serious, "This kind of dragon clan is very rare, it can be said that it is the strongest ninth-level dragon clan, no wonder those dragons outside dare not come in." Lin Lei, with your current strength, you are not the opponent of the Backbone Iron Armor Dragon at all!"

Lin Lei nodded, his courage was amazing, but he was not arrogant.

"Grandpa Delin, this spineback ironclad dragon is sleeping, the cave is so big, I should be careful, I shouldn't wake it up. Brother Zhou, where is the artifact?" Lin Lei asked in his heart.

Zhou Tianci smiled bitterly: "Lin Lei, I'm afraid you can't take the artifact quietly...... That artifact, at the top of the cavern!"

"The top of the cave?" Lin Lei raised his head, but he didn't see anything.

"The artifact is blocked by those rocks, and in order to get it, you have to break the rocks on it. In this way, it will inevitably wake up the Ironclad Dragon......"

Lin Lei and Drinkwater were silent, for them, the back-backed iron-armored dragon was a hurdle that could not be overcome.

"Actually, if you think about it from another angle, it's not a bad thing to run into a back-backed ironclad dragon. Zhou Tianci said, "Now that Lin Lei has enough Blue Heart Grass, he is one step away from transforming into a Dragon-Blood Warrior." The Ironclad Dragon is an extremely powerful existence among the dragon clan, and if he can drink its dragon blood, Lin Lei should be able to awaken ......"

When Lin Lei heard this, there was a bang in his head, as if there had been an explosion.

"That's right, with this spineback ironclad dragon, I can become a dragon-blooded warrior!" Lin Lei's mind was full of this thought, thinking of his father's disappointed eyes when he tested his bloodline ten years ago, Lin Lei's anxious mood could no longer be suppressed.

"That's right. Drinkwater agreed, "In that case, then we'll find a way to kill this Ironback!"

"The Ironclad was terrifying, especially its claws, spikes, and tail attacks. Moreover, the Spinal Iron Dragon is very fast and very flexible, so you must not be careless when attacking!" "Drinkwater has the most knowledge, he also killed a Backboneback Iron Dragon thousands of years ago, and has experience in dealing with it.

Lin Lei listened very carefully.

"The weakness of the Ironclad is in the neck, which is where its defenses are weakest and the focus of our attacks. In addition, its belly scales are not very defensive. Drinkwater added.

"Knowing its weaknesses, our ability to defeat the Ironclad has increased a lot. Lin Lei couldn't help but laugh.

Drinkwater struck at him and said, "If that's all there is to it, how can the Ironclad Dragon become the strongest dragon of its rank?"

Lin Lei asked solemnly, "Grandpa Delin, what's so powerful about it?"

Drinkwater sighed, "Before the Ironclad Dragon dies, it still has a trick to die with its opponent. Look at the spikes on its back, those are more powerful weapons than its claws! Dragons are all arrogant, especially the backed ironclad dragon, even in the face of a strong enemy, the backback ironclad dragon will not give in, and at the last moment, it will shoot out the sharp thorns on its back. If you don't have defense, even the Holy Domain can't resist it!"

"This ......" Lin Lei looked at those sharp thorns and couldn't help but swallow.

"Hehe, the Ironclad Dragon's trick doesn't work for us. Zhou Tianci smiled, "Old man Delin and I are soul bodies, no matter how powerful its thorns are, they can't shoot us." So, if you really get to that point, Lin Lei, you just need to run farther. ”

The Ironclad Dragon, resting, was lying on a stone platform, and the black air currents appeared and disappeared between breaths. Its claws hung down, and there was a black glow on it, and no one would doubt that it was terrifying. In terms of size, the Spinal Iron Armor was not large, but its momentum far surpassed that of those dragons tens of meters long.

Lin Lei slowly approached the Ironclad Dragon, and the closer he got to it, the clearer the cold feeling became.

"It's so powerful, even if I'm an eighth-level warrior now, I still feel powerless in the face of the Ironclad Dragon. If it weren't for the help of Grandpa Delin and Brother Zhou, I'm afraid I would have run as far as I would have now. ”

"Stop, Lin Lei, it will be alarmed if you go any further!" Zhou Tianci appeared on Lin Lei's right side, "Old man Delin, it's up to you!"

Drinkwater appeared to the left of Lynray, and he silently chanted the incantation, and the earth elemental began to gather around the Spinal Iron Dragon. The spine iron dragon has a strong sense of perception, and as soon as the magic element moves, it is awakened. It opened its eyes and saw Lin Lei, and that terrifying gaze made Lin Lei's body seem to freeze and unable to move.

"Earth Spirit Bondage!" Drinkwater shouted softly, and the Iron Dragon was instantly bound by dozens of ropes condensed by earth elements. Earth Spirit Binding is a ninth-level magic, cast by Drinkwater, which can bind ordinary ninth-level magical beasts.

"Lin Lei, come on!" Zhou Tianci and Lin Lei rushed up together, and Bei Bei was faster than them. The dexterous Beibei left an afterimage in the air, appearing on the neck of the spine-backed ironclad dragon in the blink of an eye. It grew much larger, and its sharp teeth bit hard.

"Roar!" the Ironclad Dragon roared as it was bitten in the neck by Beibei.

"Hurry up, I can't restrain it!" shouted Drinkwater.

Zhou Tianci came to the top of the iron armor dragon on his back and punched it down. He is a primordial god and cannot touch physical objects, and these attacks are carried out by him using the Law of Destruction. Zhou Tianci's current attack is equivalent to the peak of the ninth level, but the cultivator of the Law of Destruction has a stronger attack power than other laws, and his attack is already able to threaten the Backbone Iron Armor Dragon.

The tail of the Ironclad Dragon was the first to break free, it did not reach the Holy Domain, and it could not see Zhou Tianci, so it directly attacked Lin Lei and Beibei. Its tail swung very fast, twice as fast as Bebe, and with a piercing screech that pierced the air, Bebe was whipped and flew away.

"Beibei!" Lin Lei roared, his eyes ready to breathe fire. Bei Bei is his most trusted companion, and I don't know how many times he has saved his life. In Lin Lei's heart, Bei Bei is closer than his family. Seeing Bei Bei being attacked, the anger in Lin Lei's heart was indescribable.

"Bang!" With a muffled sound, Lin Lei kicked the back iron armor dragon in the abdomen, his physical strength was strong, and it was another angry blow, and the back iron armor dragon immediately turned over several times.

At this time, the Spinal Iron Dragon had completely broken free!

"Lin Lei, calm down, Bei Bei is fine!" Zhou Tianci shouted, "Look at the neck attack of the back-backed iron-armored dragon, and leave the rest to me!"

Zhou Tianci didn't dare to be careless, the Backbone Iron Dragon couldn't see him, but he could roughly sense his location, this was the talent of the Backbone Iron Dragon!

"Huhuhuhu......", there was an endless sound in the cave, and the tail of the ironclad dragon on his back swept wildly, obviously aimed at Zhou Tianci.

Zhou Tianci is a primordial god body and is not afraid of simple physical attacks. However, the Ironclad Dragon is a dark demonic beast, and the dark aura on its body can hurt the soul, so in the face of the dragon's tail attack, Zhou Tianci still had to dodge.

With a "boom", the place where the ironclad dragon on its back was suddenly sinking.
