"What?!You say it's the martial spell in this?" Qinglong didn't have the calmness he had just now, and shouted loudly.

"This ...... I don't know very much, but the spell just now suddenly popped out, and there was a sense of mutual attraction to the iron box, guiding me to open it. Zhou Bo replied slowly, the strange things in this cave had made him a little unbearable, how could there be that martial arts spell here?

Zhou Bo carefully observed the iron box under his feet, it was not so much an iron box as an iron coffin.

I saw that it was about three meters long and about one meter wide, and there were some quaint patterns engraved on the surface, but because the iron coffin was covered with rust, it was impossible to see what kind of pattern it was. And the iron coffin exudes a cold feeling from the inside out, and the hand touches it like a piece of ice.

"This iron coffin is not simple! This material is made of the bone spirit iron of Xilong Mountain, and I have only seen this material once in my life. ”

After sighing, he paused for a moment before he said again: "According to legend, this dark iron is made of the bones of a giant beast, but it takes a hundred years to form this bone spirit dark iron, and during this time, it must not come into contact with air, and its hardness can be said to be one of the best in the entire human world." ”

Listening to Qinglong's sigh in his ears, suddenly, Zhou Bo found that in the middle of the iron coffin, there was a black lock that locked the iron coffin tightly.

Carefully walked along the side, holding the black lock, the hand was extremely heavy, and like this iron coffin, there was an extremely cold feeling, it seemed that it should all come from the same material.

At this moment, Zhou Bo suddenly saw some small things engraved on the black lock, and carefully wiped the rust on it, only then did he see clearly that there were eight extremely small words engraved on it, and subconsciously whispered: "Cold ice and fire, you can break the lock." ”

In this regard, Zhou Bo grabbed his hair, and wondered what these eight words meant?

"I really didn't expect it! this lock is still a spiritual power lock!" Qinglong's tone was also tinged with a hint of surprise.

Zhou Bo feels that Qinglong is like an encyclopedia, as long as there is something he doesn't understand, he will definitely answer it to himself. At this time, he got up and groaned, and explained again: "This spiritual power lock is also made of bone spirit black iron, and the so-called spiritual power lock means that it must be injected with spiritual power to break the lock." ”

When Zhou Bo heard this, he hurriedly separated the spiritual power in his body and injected it into the black lock with both hands, but after waiting for a while, he found that there was no reaction.

"Hehe, don't be so anxious, don't you see the words written on it? ”

"What the hell does it mean?" Zhou Bo was a little speechless, why is this lock so weird?

"Cold Ice and Flame, naturally refers to ice spiritual power and fire spiritual power, and the original spiritual power in your body is transformed by my green evil body fire, so the attribute is fire, and if you want to open this lock, you need another kind of ice spiritual power, only two spiritual powers with different attributes are injected into this black lock at the same time, and it can be opened. Qinglong slowly said the origin of this spiritual power lock, and Zhou Bo listened to it loudly, now let him go where to find another kind of ice spiritual power!

"Senior, what should I do then?" Zhou Bo thought about it, but he could only ask for help from the green dragon in his body, and asked the green dragon in a good voice at the moment.

"Is this ......" Qinglong said this, and suddenly stopped, as if he was deliberately selling Guanzi, and after satisfying Zhou Bo's appetite, he continued: "You now open the Ice Condensation Ring and take out an Ice Cool Crystal from it." ”

After listening, Zhou Bo hurriedly opened the ice condensation ring, and finally found a white spar with white mist in the pile of 'waste' left by Qinglong for him.

After taking out the spar, Qinglong continued: "Now, you take that cryolite, stick it on the spiritual power lock, and then draw out the spiritual power from your body, pass through the ice crystal, and then inject it into the spiritual power lock." ”

Zhou Bo already understood a little at this time, his spiritual power passed through this cryolite, and it would inevitably carry the ice spiritual power in the cryolite, and then inject it into this spiritual power lock together, isn't this the cold ice and fire?

But when Zhou Bo really did it, he found it very difficult, because the lock seemed to be a bottomless pit that could never be filled, Zhou Bo had already injected half of the spiritual power in his body, but the spiritual power lock still did not react at all.

Just when Zhou Bo thought that Qinglong had made a mistake, suddenly, a bang suddenly exploded in his hand, Zhou Bo thought that the lock was opened, but after a closer look, he found that the cryolite in his hand suddenly burst and turned into a ball of white powder in his hand.

In this regard, Qinglong just said lightly: "Take another piece out, and then unlock it." ”

Sighing lightly, Zhou Bo had no choice but to take out another ice-colored spar from the ice condensation ring, and then put his hand into the spiritual power lock again, and seriously injected spiritual power.

"Spiritual power locks are very rare in the human world, because the materials and processes of manufacturing are extremely harsh, so there are not many people who know this solution. And this lock is quite simple, because there are only two attributes, and the most powerful spiritual power lock can reach nine attributes!" Qinglong saw that Zhou Bo had worked so hard to unlock it, so he opened his mouth to tell him something about this spiritual power lock.

Zhou Bo was really exhausted at this time, he never expected that it would be so difficult to unlock a lock!

And when his physical strength was close to exhaustion, suddenly, the spiritual power lock began to shake slightly, and the whole body was covered with black light, making a knocking sound, as if he could no longer withstand the power inside, and after a violent shaking, a loud bang exploded, and it broke apart.

"Be careful!" It was Qinglong who was the first to discover the abnormality, shouting vigilance, and hearing this, Zhou Bo's whole body was also shocked, and his attention was highly concentrated.

He suddenly found that after the black lock broke, the iron coffin under his feet suddenly cracked a crack in the middle, and was slowly opening downward, and before he could react to what was happening, the iron door seemed to be blocked by something inside, and it only stopped when it was opened, forming two slopes on the left and right on the iron coffin.

Zhou Bo cautiously moved forward, and he saw that inside the iron coffin, there was a huge white bone remains, which looked very similar to the bone piles below, and it was estimated that he had been dead for a long time.

Zhou Bo stood up boldly, turned sideways, and carefully jumped into the coffin, and then began to carefully examine the white bone in front of him.

This white bone is really huge, the three-meter-long coffin is more than two meters thick, and the white bone is just enough to fit, presumably he must have been a strong man before his death.

Beside him were two small black boxes, Zhou Bo reached out and picked up one of them, and found that the iron box was not locked and could be easily opened.

The iron box is very light, and when he opened it, it was just a black spar, which made Zhou Bo, who was full of anticipation, suddenly disappointed, he didn't expect that what he had worked so hard to find was not a treasure, but just such a broken stone!

Just as Zhou Bo wanted to put the stone down, Qinglong said with a smile: "You are really lucky!"

"Senior, what do you mean?" Zhou Bo was puzzled and hurriedly asked. After Qinglong stopped laughing, he said slowly: "If Rong guesses correctly, this should be the Martial Spirit Stone." ”

"What?" Zhou Bo was shocked in his heart, he didn't expect that the so-called martial soul stone was the inconspicuous broken stone in his hand.

Qinglong laughed at this time: "If you don't believe it, you can rush in spiritual power to try." ”

Zhou Bo suspiciously urged the letter into one of the spiritual powers, but just as he touched it, suddenly, the stone emitted a blazing heat, and it turned into an extremely gorgeous white light, and it slammed towards Zhou Bo's chest. Zhou Bo couldn't dodge, screamed, and fell unconscious in the iron coffin.

"How are you feeling?"

Qinglong's old voice suddenly sounded, Zhou Bo raised his heavy eyelids, and was surprised to find that he had not fainted, but there was a slight pain in his chest.

At this moment, he was still sitting in the middle of the iron coffin, but the white bones under him had turned into a ball of white powder, covering the entire iron coffin, and he suddenly remembered Fu Zuo in Qingxi's mouth in his mind, it seems that this martial arts spell really played a role in protecting the bones!

"Senior, I'm fine, it's just that my chest hurts a little!" Zhou Bo sat up straight at this time and found that everything in his body was normal.

Slowly sinking his mind to his heart, he saw the strange symbols flipped in his mind, still the same incomprehensible, but the number was more than before, in this regard, Zhou Bo was even more sure that the broken stone just now was the martial soul stone, but what was the use of this martial soul stone? and why did it fly into his body?

"It's incredible! This spell has flown into your body again, is it really related to that power?" Qinglong said as if talking to himself, his voice very small.

"That power, what kind of power?" Zhou Bo vaguely heard Qinglong say these words just now, and asked curiously.

"No, no, you better hurry up and take a look at the other two boxes!" Qinglong hurriedly denied it, seeing that his cramped tone was like lying had been exposed, but Zhou Bo didn't ask any more, because curiosity had driven him to open another iron box.

The iron box was opened, but there was nothing inside, nothing was contained, which made Zhou Bo depressed to death, stupidly looking at the empty box in his hand, and the fiery anticipation was instantly extinguished. He thought it would be an exercise or something, but now there was nothing, and this sense of loss made Zhou Bo very frustrated, and he threw it back into the iron coffin as soon as he threw it away.

"Don't be in a hurry to throw it away, this box might be a treasure, so put it away quickly. Qinglong saw that Zhou Bo wanted to throw away the box, and hurriedly spoke.

"Baby?" Zhou Bo heard Qinglong say, hurriedly bent down and picked up the box again, and then began to carefully examine the iron box in his hand.

The box is very small, only half a palm is the size of a hand, there is no cold feeling of the iron coffin, under a closer look, the box is covered with lightning-like patterns, not looking carefully, I thought that the box was cracked, at this time, Zhou Bo rubbed it with his hands, feeling that the lightning pattern was very exquisite, thinking that this might really be a treasure, urging a trace of spiritual power to open the ice condensation ring, and threw the iron box into it casually.

"Senior, how are we going to destroy this tomb now?" As he spoke, Zhou Bo slowly stood up, looking at the white bone corpses piled up under him, and his teeth suddenly remembered the purpose of coming this time.

"Boom!" A bang suddenly exploded from above, Zhou Bo raised his head suddenly, and his scalp suddenly tingled, because he saw that on the top of his head, a boulder was falling rapidly, not only completely blocking his vision, but also the shocking sense of oppression made Zhou Bo forget to flee for a while.

"Run!!"

Qinglong saw that Zhou Bo was staying there, motionless, and immediately hurriedly shouted loudly. Hearing this, Zhou Bo was startled, only to find that the boulder was already very close to him. No longer hesitated, his legs full of spiritual power exploded, and he quickly jumped down from the iron coffin.

Before it fell, Zhou Bo heard a loud bang, it turned out that the iron coffin he was staying in just now was hit by a boulder at this time, and the four iron chains couldn't withstand the huge impact force at all, and they broke one after another.

And the iron coffin was not pulled by the iron chain, and at this moment it fell rapidly with the fall of the boulder. On the roof of the cave, large and small stones fell down like hailstones, and these stones fell on the pile of white bones, making a strange sound and making the whole cave shake with it.

"It's not good, this cave is about to collapse!" Qinglong burst into tears, and Zhou Bo remembered that Qingxi had said that the cave last time also collapsed, and in the end, it was the three of them who escaped with the help of Jiu Tianyun.

At that moment, Zhou Bo hurriedly unfolded his body and ran towards the entrance of the cave at full speed, looking at the rapidly falling stones in front of him, Zhou Bo was like a monkey, dexterously shuttling among them, and there was no panic on his face, although sometimes Zhou Bo was very reluctant, but those boulders just couldn't hit him, perhaps, this is inseparable from the devil training of Tongyao for half a year!

After jumping a few times, Zhou Bo saw the hole in front of him, and rushed in with an acceleration.

After jumping out of the cave, Zhou Bo heard the sound behind him even louder, it is estimated that the entire cave has been buried by the boulder at this moment, he does not dare to have any reservations at this time, he has already transferred all the spiritual power of his body to his legs, and his body method has been used to the extreme, and he is running forward quickly.

Now Zhou Bo has a feeling of racing against time, as long as he slows down, it is estimated that he will be buried here forever, and he only has one thought in his heart now, that is, to run back to Jiutianyun as soon as possible, and let it escape with him as soon as possible.

Just when Zhou Bo was running rapidly, Zhou Bo suddenly felt a power attacking him, he thought that a boulder had hit him, and subconsciously fought back, but found that his strength was like hitting a soft wall, and then disappeared strangely.

When he was puzzled, he heard Qinglong say: "Put away the spiritual power, and leave the rest to Jiutianyun!" Zhou Bo was overjoyed when he heard this, but he didn't expect Jiutianyun to come to him, it was really psychic to the extreme! Although it was too dark around him to see Jiutianyun clearly, Zhou Bo felt that his whole body was surrounded by a soft object, so he was relieved.

Zhou Bo couldn't help but fall into deep thought in the package of the Nine Heavenly Clouds. On the one hand, he was happy to destroy the tomb, so that the rotting weed would wither, and the people of the city would no longer suffer from that strange disease. On the other hand, Zhou Bo was also puzzled by all kinds of mysteries, what was this curse, why was it absorbed by himself, and what happened to those dead bodies and bones? Who was the murderer? All kinds of questions made Zhou Bo's happy mood for destroying the tomb a little heavier.
