Behind Qin Mu, Liu Qingyu followed him closely, and in the rear, there were a large number of figures, those were all strong people from all sides who rushed into the Thunder Lake, obviously, at this time, everyone knew that it didn't seem to be simple under the Thunder Lake.

Qin Mu glanced at the back, and that movement made him frown slightly, but he shook his head helplessly, since this situation was unavoidable, then it was up to each other's abilities.

Retracting his gaze, Qin Mu's gaze was cast to the bottom of the Thunder Lake, as he gradually deepened, he could perceive the vastness of the Thunder Lake, and under the Thunder Lake, the terrain was also extremely peculiar, among which silver-like boulders stood everywhere, as if forming a schist reef between them, and at a glance, there was no end in sight.

Qin Mu swept in the direction of those rocks, his sharp gaze kept sweeping around, and after a long while, his heart suddenly moved, and he suddenly looked down, where a rather strong energy fluctuation suddenly came out again.

As far as Qin Mu could see, there was a silver vortex forming below, and at the end of the vortex, a thunderbolt of light slowly floated up, and in that light cluster, there was a thunder heart.

Qin Mu looked at this scene, his figure rushed out abruptly, but after a while, it suddenly froze, and his face was full of surprise, looking down.

There, there is an extremely large thunder rock gully, the ravine is bottomless, as if connected to the depths of the earth.

On the two walls of the ravine, there are countless stone caves, with the help of the reflection of the water of the Thunder Pulp Lake, Qin Mu can vaguely see that in those stone caves, there seem to be some figures sitting cross-legged.

It's just that those figures are lifeless. Qin Mu's eyes looked at the bottomless thunder rock ravine in front of him with some surprise, it seems that this should be the source of those thunder hearts that keep coming out, right?

Qin Mu's figure slowly swept close to the thunder rock ravine, and finally suspended in front of a stone cave, at this distance, he could already see clearly, in the stone cave, there were indeed figures sitting cross-legged, but at this time, these figures were already as thin as bones, their bodies were filled with the color of thunder and lightning, from their bodies, Qin Mu could detect a pure thunder power that was compressed to the extreme.

Obviously, every inch of skin of these corpses in all the years of sitting. They were almost infiltrated by the power of thunder, and coupled with the strong water pressure, these corpses almost turned into dry corpses that were completely condensed by the power of thunder.

Qin Mu looked at these dried corpses that had almost turned into thunder, and after a moment, his eyes suddenly moved, and then he turned to the abdomen of the dried corpses, where he could faintly see a trace of extremely faint evil black qi entangled.

However, this kind of evil black qi was almost blocked and suppressed by those pure thunder powers, and this also made these black qi unable to control their corpses, forming a dead corpse like the one Qin Mu had encountered before who only knew how to kill indiscriminately.

"These people deliberately chose to sit under this thunder lake, using the power of thunder here to suppress and erase the evil qi that invaded their bodies, and prevent them from becoming the kind of dry corpses who only know how to kill after they are completely dead. Qin Mu's eyes flickered, and soon he vaguely guessed some clues, and then his eyes were slightly complicated, these strong people are undoubtedly worthy of admiration, in order to prevent themselves from becoming monsters eroded by evil qi, they would rather sit at the bottom of this thunder lake and turn their bodies into thunder.

A faint muffled thunder suddenly came from a stone cave not far away, and then Qin Mu saw it, and the silver corpse in it suddenly burst into brilliant thunderbolts, which were crazy shuttling in his body, looking like a small sun from a distance.

As the thunder became more and more intense, suddenly, the silver corpse exploded suddenly, and between the explosion of its corpse, a silver light cluster rose up, and within that light cluster, a silver heart beat slowly.

Qin Mu looked at this scene and exhaled deeply, he finally understood why there was a steady stream of thunder hearts rising at the bottom of this thunder lake, it turned out that these thunder hearts were all tempered by the power of thunder for thousands of years after those strong people sat down, and finally took shape.

And when the heart of thunder appeared, the evil qi that remained in their bodies was also wiped out by the extremely powerful power of thunder at that moment.

"After all, I fulfilled my last wish before I died. Qin Mu muttered to himself.

"It turns out that this is how the heart of thunder appeared. The voice of surprise also sounded from behind at this time, Qin Mu turned his head, and then saw that Tang Xian'er, Qin Mu and many strong people from all parties had all arrived here, and then looked at the thunder rock ravine in front of him with a moving face.

Obviously, the previous scene of the silver corpse exploding and turning into a thunderous heart rising was also in their eyes.

"Haha, so many silver corpses, if they all turned into the heart of thunder, how terrifying would it be?"

"It's really broken into the treasure pile, this Thunder Heart, which is so rare in the Falling Spirit Mansion, actually has such a number here. ”

"Yes, if you can catch a few, this trip will be worthwhile!" The eyes of the powerhouses of all parties at this time were undoubtedly extremely hot, and they looked at the many stone caves on both sides of the huge thunder rock gully, with greed and coveting in their eyes that could not be concealed.

A commotion spread among the powerful people from all sides, and then soon, someone couldn't hold back the greed in their hearts, rushed out, and then rushed to the cave in the thunder rock ravine.

And just as they rushed away, the fluctuation caused by that kind seemed to become the last straw that broke the camel's back, and in the many stone caves, many silver corpses exploded at this moment, and the hearts of thunder, flashing with tempting thunder, rose one after another.

And every time the Thunder Heart appears, those strong people from all sides will compete with each other, and for a while, this thunder rock ravine immediately becomes extremely chaotic and violent.

Qin Mu frowned and looked at the many powerhouses who were fighting hard, then stretched out his hand to summon Liu Qingyu to his side, and said, "Let's also collect some Thunder Hearts, this thing will also be of great benefit to your cultivation." "Liu Qingyu is an immortal Saint Qingyin Jiao clan, his body is strong, if he can obtain some thunder hearts, he can make his already strong body to a higher level.

"Hmm. Liu Qingyu nodded excitedly, she seemed to like this kind of treasure hunt very much.

The two figures swept out almost at the same time, and then rushed into the huge thunder rock ravine, and the two of them struck, quickly taking the rising thunder hearts into their pockets.

And when Qin Mu and the others started, Qin Mu, Tang Xian'er and other big forces couldn't bear it, and immediately the sound of breaking wind sounded, and they all rushed straight into the thunder rock ravine, and then used various means to collect and snatch those thunder hearts.

And with this scramble, there will naturally be a bloody fight, in less than ten minutes, someone was killed in that kind of robbery, and the blood drifted in the thunder pulp, so that in this thunder rock ravine, there was a faint smell of blood.

However, when everyone was fighting for those thunder hearts, no one noticed that in some stone caves deep in the thunder rock, some of the silver corpses that looked exceptionally strong were attracted by that kind of blood, and on their corpses, there was a trace of black qi rising strangely.

Especially at the bottom of the thunder rock ravine, there was an exceptionally large cave, and at this time, in that cave, there was a silver figure about a few feet tall, and on the surface of his body, there were strange and evil black magic patterns.

Moreover, his eyes, which had been closed for thousands of years, also trembled slightly, as if he was about to awaken a demon.

Hum! Qin Mu's palm was bent into a claw shape, and the suction power in his palm suddenly surged, and a thunder heart that had just floated out of the stone cave not far away suddenly roared, and then he grabbed it.

"The fourth!" Qin Mu grabbed the Thunder Heart in his hand, feeling the power of the pure thunder surging in it, and his eyes couldn't help but pass a touch of heat, in just ten minutes, he had already obtained four Thunder Hearts, and this harvest was quite expensive.

Putting away this Thunder Heart, Qin Mu glanced at Liu Qingyu in front of him, at this time, the latter was also quite excited to search for the Thunder Heart, and in the distance, there were constantly violent spiritual power fluctuations, and faintly, some fighting sounds could be heard.

Although there are a lot of silver corpses in this thunder rock ravine, after all, not every silver corpse can eventually turn into a thunder heart, so the number of thunder hearts is far from satisfying the endless greed in everyone's hearts.

Moreover, the news here was obviously spreading continuously, so Qin Mu could also see that from time to time, there were some strange powerhouses rushing into the Thunder Lake with blazing eyes, and then coming straight to them.

Thinking about it, many strong people have received the news, and then they want to rush to snatch the heart of thunder, and in this kind of situation where there are many monks and few porridges, it is inevitable to rush to snatch.

But fortunately, those guys have also heard of Qin Mu and the others, and know that the two of them are a little tricky, so for a while, no one came to harass them for the time being, but Qin Mu knew that this was just a temporary situation, and when they got it, there were fewer and fewer thunder hearts that could be collected, and the reason of those strong people would gradually be diluted by greed.

Sooner or later, a rather tragic scuffle will break out here. Qin Mu's lips pursed slightly, but there was a fierce look in his eyes, he was happy to be clean if these people didn't provoke him, but if he really wanted to focus on the Thunder Heart in his hand, then he could only let some people know what it meant to steal chickens and rice!

Thinking of this, Qin Mu also retracted his gaze, his body moved, and gradually walked towards the depths of the thunder rock ravine, and the outer thunder heart was almost snatched away.

Not far from behind, Qin Mu looked indifferently at Qin Mu and the others who were facing the depths of the Leiyan ravine, and a fierce color suddenly flashed in his eyes.

"Hey, the two of them seem to have collected nearly ten Thunder Hearts in their hands, which is not less than us. Beside Qin Mu, a man grinned, he was one of the three people who fought Liu Qingyu in Shicheng, and he was also one of the so-called four evil generals in the Netherworld Sect, and his strength was quite good.

"It's okay, let's let them collect it slowly. Qin Mu smiled faintly, but that smile was particularly gloomy: "When he collects enough, I will ask him to hand it all over to me!" Although the strength of Qin Mu and the others was slightly different from his expectations, this did not make Qin Mu feel jealous of this, such a lonely person dared to compete with his Netherworld Sect for things, he really didn't know whether to live or die.

"Collect the heart of thunder as much as possible, whoever dares to compete with us, kill it. Qin Mu turned his head and ordered, and when those Netherworld Sect powerhouses heard this, a fierce light suddenly welled up in their eyes, and then they rushed out with a cruel smile, rushing towards those places where thunder light was rising.

Qin Mu didn't know much about some of the calculations of the Netherworld Sect, at this time he was gradually going deep into the Thunder Rock Gully, and in the next ten minutes or so, he collected two Thunder Hearts, but as he continued to dive, Qin Mu frowned slightly and found a problem, that is, it seemed that as he went deeper and deeper into the Thunder Rock Gully, the evil qi contained in the silver corpses in those stone caves became stronger.

Obviously, the erosion of these strong men during their lifetimes was particularly serious compared to the previous ones.

This kind of Dongfu sect, in that era, should also be rampant, looking at these scales and numbers, it is not weaker than a super sect, but I didn't expect that it would still end up like this under the attack of the evil clan.

"Hehe, big brother, I have six Thunder Hearts!" When Qin Mu frowned at this discovery, Liu Qingyu also came over, and at this time, there were two Thunder Hearts floating in her little hands, and it seemed that her harvest this time was also quite large.

When Qin Mu heard this, he also smiled, and just wanted to speak, his eyes suddenly sank, and then he slowly raised his head, only to see that around there, I don't know when five figures appeared, at this time, they were looking greedily at the two thunder hearts in Liu Qingyu's hands.

It seems that this kind of trouble has finally come to the door.

"A few, there are a lot of other places in the heart of thunder, I advise you to collect it honestly, don't have a hot head for a while, but put yourself in. Qin Mu stared at the five people and said lightly.

He could sense that the strength of these five people was not weak, and four of them were at the peak of the Nine Yuan Life and Death Realm, and the person at the head had faintly stepped into the level of semi-gathering gods, and this kind of strength was already quite powerful.

"Hey, what a crazy tone. Hearing Qin Mu's words, a cold light suddenly flashed in the bald man's eyes, he looked at Liu Qingyu beside Qin Mu, he had obviously heard of the latter, if it was in normal times, he didn't want to provoke this little evil star, but at this time, under the attraction of the heart of thunder, it was obvious that many people's sanity had become a lot weaker.
