"Let's open the cave." Lin Mu said.

The silver tower in the hands of the three of them flew into the air at the same time, and the silver tower suddenly shook, and there was a faint thunder sound coming from it.

Suddenly, three brilliant silver beams of light shot out from the silver tower, intertwined in the sky, and finally shot into the thunder light.

Suddenly, ripples and fluctuations suddenly appeared on the edge of the originally calm thunder light, and a low thunderclap rumbled out, and a trace of destructive fluctuations emanated.

The sound of thunder became louder and louder, and a ray of light suddenly emerged from the edge of the thunder light, and then extended at an unexpectedly fast speed, and finally turned into a light path filled with thunder light, and at the end of the light path was the Thunder Emperor Cave Mansion.

The huge stone door, which was about a thousand feet long, slowly opened, and a wave of ancient and wild waves poured out like a tide.

"Let's go inside."

With a move of Lin Mu's arm, all the three silver towers were put away by him, and then his figure swept towards the stone gate at the end of the light path, and Lin Dong and Mu Lingshan quickly followed.

The moment he entered the stone gate, the reincarnation purple lotus flew out of Lin Mu's palm, emitting a purple light, enveloping the three of them inside.

The surrounding scenery changed rapidly, and in front of them, there were countless thunder figures, all of them holding a thunder bow in their hands, and the lightning arrows that flashed with electric arcs were already on the string.

Before Lin Mu and the three of them could see the situation clearly, countless thunder arrows shot towards them like raindrops.

"Let's kill it."

Lin Mu urged the reincarnation purple lotus, took Lin Dong and Mu Lingshan, and rushed towards the thunder arrows in the sky.

Countless thunder arrows shot at the light shield formed by the reincarnation purple lotus, like rain falling into the surface of a lake, rippling with small ripples, and then disappearing.

When the first wave of thunder arrows was shot and the second wave of thunder arrows was still brewing, Lin Mu and the three of them had already killed in the Thunder Light army, Mu Lingshan and Lin Dong took out the coffin lid of life and death and the Burning Heaven Ding respectively, and rushed inside.

After those thunder figures were scattered by them, they did not disappear, but merged into the other thunder figures.

"Big Brother Lin Mu, the more we kill, the more powerful the remaining Thunder Light Figures will be." Mu Lingshan said, as the number of thunder light figures eliminated increased, she felt that something was a little tricky.

"Follow me!"

Lin Mu pinched the seal with both hands, and a huge purple beam of light shot out from the reincarnation purple lotus, rushing towards the thunder light figure in front of him, and instantly opened up a passage, and the three of them quickly rushed inside.

"There is a space fluctuation in front, and it should be the real reincarnation cave inside." Lin Dong looked up at the end of the Thunder Light Army, where a silver circle of light slowly rotated.

"Be careful!"

Mu Lingshan snorted, only to see that among the surrounding thunder light army, there were ten sturdy figures with bright bodies and thunder armor swept out, they were holding thunder spears, and their strength was much stronger than other thunder light figures.

The ten thunder spears brought up astonishing fluctuations, and with the momentum of encirclement and suppression, they shot towards the vital points around Lin Mu and the three of them.

Lin Mu's mind moved, and a spiritual power barrier enveloped the three of them, and the thunder spear stabbed on the spiritual power barrier, and was instantly bounced out.

"Let's go inside." Lin Mu took Lin Dong and Mu Lingshan and swept into the silver aperture.

The moment it swept into the silver aperture, the silver light filled the eyeballs, and when the light disappeared, a vast land appeared in front of them, and there were groups of temples on the land, but these temples were now in ruins.

The whole land, showing a gray and black color, a dilapidated atmosphere, rippling in this heaven and earth.

"Big brother." Lin Dong looked at Lin Mu with a solemn face, and he sensed the breath of a strange demon in this cave mansion.

"The owner of this cave mansion should be the owner of a certain generation of Thunder Ancestral Talisman, they were attacked by alien demons, and the entire cave mansion was destroyed in one fell swoop, just like the situation in the Great Wilderness Monument." Lin Mu said.

"I wonder if the demon was finally destroyed?" Lin Dong said.

"The vitality of the alien demon is extremely strong, it should not have been destroyed, it is likely that it was sealed by the owner of the cave, we have to be careful." Lin Mu said.

"Hmm." Lin Dong nodded, he also had a deep understanding of how difficult the alien demons were.

"Brother Lin Mu, look ahead."

Mu Lingshan suddenly spoke, pointing her little finger ahead, where there was a dilapidated ruined square, and faintly, you could see a figure in the square.

Lin Mu's figure swept out, and soon came to the sky above the square, and found that there were thousands of dead corpses sitting on the square, all of which were facing south, raising one hand, as if they were joining forces to resist something.

"Thousands of strong people have landed like this, it seems that the alien demons who invaded here back then were very strong." Lin Dong pursed his lips.

With a wave of Lin Mu's robe, a gust of wind blew, and where the wind passed, most of the dead corpses directly turned into flying ashes and scattered, leaving only eighteen dead corpses still sitting there quietly.

"Demon corpse!" Lin Dong's pupils shrank, this dead corpse was exactly the same as the demon corpse he saw in the Alien Demon Domain, except that these demon corpses were much stronger than the demon corpses in the Alien Demon Domain.

The eighteen demon corpses opened their deep-set eyes, and a dark black flame ignited in their eyes.

"These demon corpses were all powerhouses of the Death Xuan Realm before they were alive, and in their dantian, there is a Death Silence Pill, which is of great benefit to the impact of the Death Xuan Realm." Lin Mu said.

When Mu Lingshan and Lin Dong heard this, their eyes lit up.

The two of them are currently in the Consummation of the Birth Mystery Realm, and they are about to impact the Death Mystery Realm, and this Death Silence Pill has a great attraction for them.

"I'll take action to suppress them, crack the alien demonic qi on their bodies, and Lingshan will take the Death Pill." Lin Mu said, and then his figure swept and appeared in the sky above the eighteen demon corpses.

The Great Desolate Monument flew out of his palm, instantly rising to the size of dozens of zhang, and as the Yuan Force continued to inject into it, a yellow light burst out from it, enveloping all the eighteen demon corpses, and the demon corpses struggled a few times, and then there was no reaction.

A light array suddenly appeared in Lin Dong's palm, rising to the size of several zhang, and then a strange beam of light burst out from it, hitting the dantian of a demon corpse.

The troll corpse suddenly let out an earth-shattering roar, struggling hard, black flames surging wildly, trying to break free from the suppression of the Great Desolation Monument, but with Lin Mu's help, any struggle was in vain.

Under the irradiation of the strange beam, the skin at the demon corpse dantian actually began to dissolve rapidly, but after a while, it completely dissolved, revealing a pitch-black pill.

Seeing this, Mu Lingshan's petite figure quickly swept out and held the pitch-black pill in his hand.

At this time, the black flame in the eyes of the demon corpse also dissipated, and the struggling action stopped abruptly, and with a bang, it fell heavily to the ground.

Immediately after that, the three of them drew gourds in the same way, and did something to the other demon corpses, and in less than ten minutes, they took out all the Death Silent Pills in the eighteen demon corpses.

"Big Brother Lin Mu, eighteen Dead Silent Pills, I didn't expect that as soon as we came in, we would find such a good thing." Mu Lingshan's big eyes looked at Lin Mu brightly, and said excitedly.

A Dead Silence Pill is worth at least millions of Xuanyuan Dan outside, and eighteen Dead Silence Pills, which are almost worth 100 million Xuanyuan Pills, is indeed a big gain.

"You two divide it, there are still a lot of such demon corpses in the cave, let's find some later." Lin Mu said that he was already a consummate of the Death Realm, and the Death Silence Pill was useless to him.

In that great battle, there must have been many people's corpses eroded by the demonic qi and turned into demon corpses.

"Thank you, big brother Lin Mu." Mu Lingshan smiled and handed nine of the Death Pills to Lin Dong.

"The people in the back are coming in soon, we have to hurry." Lin Dong said that their main purpose was to find the Thunder Ancestor Fu, if they delayed the time because of the Death Silence Pill and let others take the lead, it would be a little more than worth the loss.
