After entering this underground world, Chen Xuan learned a secret that he couldn't solve, this soul stone in his soul sea was obviously countless times stronger than this bead condensed by chaotic qi, so what was this piece in his soul sea, Chen Xuan felt that he had just understood something, but he had more secrets that he didn't know.

"Senior, I want to know, what's going on here, how did you end up here with the Heart Demon King!" Chen Xuan asked.

"I didn't expect you to know the Heart Demon King!" the old man's voice wondered.

Chen Xuan said what had just come in as it was, even the old man in the soul body in this soul stone didn't believe that Chen Xuan could defeat the soul of the Heart Demon King, although his soul was already ten million times weaker, but it was not something that the Yuan Martial Realm could defeat, but Chen Xuan didn't explain too much.

"It's a long story, in those years, the Heart Demon King relied on his own cultivation of the Heart Demon Heart Sutra, killing innocents everywhere, countless lives died in his hands, basically where he passed, the blood flowed into the sea, and finally I happened to pass by a planet, seeing that he was slaughtering, I took action to stop it, and it has been from a distant planet to here, after a year of fighting, we actually didn't distinguish the winner or loser, and finally both used a stunt, both seriously injured each other, we fell into this deep mountain together, the battle did not stop, until we were exhausted to stop fighting, and finally led to such an ending!" the old man sighed.

"After a year of fighting!" Chen Xuan's expression was shocked again, he could fully feel the cruelty and heroism of that battle, it must have been a landslide and tsunami, and the stars were shifting.

After some words just now, the old man's voice began to slowly weaken, Chen Xuan didn't even hear the next few words clearly, and hurriedly asked again.

"Senior, the junior has something unclear, please give me advice, I have a friend who suddenly passed by here and was suddenly irradiated by a beam of light, all the cultivation disappeared, can the senior guide the junior!" Chen Xuan said quickly.

"Isn't it all without a trace of true qi flowing, and no matter how much you cultivate, you can't make up for it, is that true?" the old man's faint voice sounded again.

"Yes!" Chen Xuan said quickly.

"This is caused by the impact of the demonic qi and the immortal qi here, blocking all the meridians in his body, that is to say, locking his strength, commonly known as the 'immortal demon lock' Unless he can find a way to remove the impact of the immortal qi and the demonic qi, as long as these two breaths are not excluded from his body, he can only stay in the current state forever!"

The old man's voice said lightly, the breath was almost inaudible, if it weren't for Chen Xuan's strong soul, he wouldn't even be able to hear what the other party was saying.

"May I ask senior, is there any way to cure it?" Chen Xuan asked urgently again.

The old man seemed to be silent, did not answer Chen Xuan's question, and waited for more than a dozen breaths before a voice came out.

"It's not impossible!" said the old man again.

"Senior, please speak!"

"Qilin blood with phoenix blood can break this shackle, but these are the overlords of the king beasts, and you can't get them with your current strength, because the lowest strength of these king beasts is the earth spirit realm, plus the power of the powerful bloodline, ordinary humans can't get their blood at all!" The old man's voice Chen Xuan leaned in front of him to hear it clearly.

"Even if there are thousands of difficulties, I will obtain Qilin blood and phoenix blood!" Chen Xuan said firmly.

The old man ignored Chen Xuan's tone, and said lightly again.

"Outside is my weapon, 'Emperor Blade', the current refining method should be lost, but I still have some refining methods there, it is difficult for your current strength to take him away, if you can take it away, I hope you can treat it well, after all, he has been with me for hundreds of thousands of years!" the old man said with a tone of relief.

"Seniors, don't worry, if the juniors can take it away, they will definitely not let the Flying Blade see the light of day again!" Chen Xuan said solemnly.

"And that is an evil blade, I hope you don't think about collecting it, once it is stained, it will cause countless killings, because that Dao weapon has been stained with countless blood, and if you don't drink blood for a moment, it will absorb it on its own, and when the time comes, it will kill people on its own and absorb their blood, so if you can destroy it, destroy it!" the old man said solemnly.

"Juniors understand!"

"Okay, it's time for me to disappear too, all the things here are left!" After saying that, the soul stones suddenly dimmed, and the old man's voice disappeared with it.

"Senior, senior......" Chen Xuan asked several times in a row, but no one answered, it seems that this senior has really reached the point where the oil has run out.

Chen Xuan's divine sense withdrew from the spirit ring, and slowly realized what happened just now, Xiaoxiang's situation was already known to him, it was caused by the impact of the immortal qi and demon qi here, forming an immortal and demon lock in the body, locking the strength of the whole body, unless the qilin blood and the phoenix blood could lift this immortal and demon lock.

Chen Xuan's divine mind opened the spirit ring of the Heart Demon King again, and the spirit entered an incomparably wide space again, and the things placed in it were no less than the spirit ring of the old man just now, but the things placed on both sides were completely different.

There are actually countless grains of Shura Dan in this, but it is countless times more advanced than these Shura Dan in Chen Xuan's hand, these Shura Dan release pure Shura Qi, there is no bloody Qi at all, each grain is crystal clear.

There were also a lot of magic weapons placed in it, Chen Xuan didn't count them carefully, but a pile of red shiny stones attracted Chen Xuan's attention, and boundless demonic qi was released on it, and these released demonic qi filled the entire spirit ring.

"Magic Crystal!"

Chen Xuan exclaimed, it seems that Chen Xuan also knows something about this thing, this is the magic crystal used by the demon clan for cultivation, which is the same as the immortal stone cultivated by humans, but the number of pieces is not very many, only more than a hundred.

After a simple inventory of things, Chen Xuan's divine sense retreated again, Chen Xuan basically understood everything that happened, the most important thing at the moment was how to take away these two Dao weapons, Chen Xuan couldn't get close to these two Dao weapons at all, and the power released from them couldn't let Chen Xuan get close at all.

Dao weapon, but a Heavenly Spirit level person, Chen Xuan has not dared to plan to the extent that even the Heavenly Spirit Realm can be subdued, but now that they have completely lost their spirituality and become ownerless things, it is not impossible, if the Heart Demon King and this dead old man have not been dead for a long time, Chen Xuan will not have such an idea anyway, because at that time, the spirit of this Dao Weapon is still there, and no one will want to take it away.

Reaching out and grabbing one end of this giant axe, a huge force immediately bounced Chen Xuan out, and the moment he held the giant axe, Chen Xuan even felt a fierce beast pounce towards him, this fierce beast opened its mouth, and then an irresistible force sprayed out, directly sending Chen Xuan out of the air.

"Boom!"

Chen Xuan's body was knocked into the opposite wall, and the cave roared, and even the corners of his mouth flowed blood, and it seemed that he was not lightly shocked by the force of the rebound just now.

"It's so strong, it's worthy of being a Taoist weapon!" wiping the blood from the corners of his mouth, Chen Xuan muttered to himself.

Walked over again, but this time Chen Xuan didn't reach out to touch him again, Chen Xuan knew that his current strength couldn't take it away at all, anyway, he still had some time now, it was better to let his strength break through to the late stage of Yuanwu here, and then see if he could collect it.

In it, it is time for his evil spirit to be promoted, now there are countless materials, Chen Xuan is not worried at all, Chen Xuan's promotion, as long as he takes a little time, he can be promoted to the middle or even late stage of the Yuan Instrument.

As soon as he wanted to do it, he immediately took out countless pills, all of which were absorbed by the Heaven Swallowing Furnace, and then turned into a torrent of pills, flowing in the Heaven Swallowing Furnace, slowly condensing into crystals, preparing to bring a lack of vitality to Chen Xuan when he broke through.

Sitting on the ground, immersed in his mind, ready to break through the realm of the late Yuanwu period, now there is nothing missing, there is a pill to have a pill, the Yin Yang Glazed Pill Chen Xuan has not planned to use it yet, although taking it can immediately break through a class, but this is not what Chen Xuan needs, Chen Xuan wants to keep himself and use it at a critical moment.

Time passed little by little, and in the blink of an eye, a day passed, Chen Xuan's body was still sitting on the ground, and the flowing blood ran in his rough veins, making a ding-dong sound.
