After resting in place for a while, Xia Mu took a deep breath and continued to crawl in the original direction.

"It's ...... Blue Sea Snake Puppet!" "Along the way, Xia Mu saw a snake-shaped puppet with a blue color, but unfortunately, these puppets have been completely destroyed, and the parts are scattered all over the place, as if there was once a supreme powerhouse who shot and killed all the puppets here.

Among these destroyed Blue Sea Snake Puppets, there are two extremely large heads, which are the Blue Sea Snake Puppet Kings, who have the combat power of the Immortal Realm, but they are still completely destroyed.

"This blue ocean abyss...... It can't be caused by the battle between the master of the Thousand Machines Hall and a strong enemy back then!" Xia Mu guessed in his heart, all the things he encountered along the way made it difficult for him not to think in this direction.

The destroyed puppet parts are cold to the touch, and I don't know how long it has been, but they are still hard and have not been corroded by the years.

Xia Mu picked them up and examined them carefully, and found that although the internal imprinted rune array was intact, the key points had been destroyed and could not form a whole, so naturally it could not be operated.

He didn't know what kind of fierce battle took place here back then, but it was obvious that the enemy was very strong, and he could destroy the internal rune array of these puppets without destroying their appearance, this kind of means, Xia Mu was sure that ordinary immortal realm powerhouses could not do it, and it was necessary to be proficient in the way of puppets, and the immortal realm powerhouses who were very clear about the internal structure of puppets could erase the key points of their internal rune arrays without destroying the puppets.

Or maybe it wasn't an immortal realm powerhouse who struck, but an eternal saint.

To some extent, the latter is more likely, after all, it is rumored that the owner of this Thousand Machines Hall fell because he offended an eternal saint.

Of course, no one can say what the actual situation is, except for those who experienced it back then.

After thinking for a while, Xia Mu decided to move on, to see what kind of secret was buried in this blue sea abyss, if he didn't take a look, it would always be difficult for him to let go of it, and there were too many questions.

Of course, the main reason is that Xia Mu can't go out at all now, and he can't find the right direction, since this is the case, it is better to continue to explore in this direction generously, if it is too dangerous, it is not too late to turn around and run away.

However, Xia Mu felt that most of the time he would not encounter any danger, or that the danger existed, but back then, it was cleaned up by others in advance, and the evidence was the many puppet wreckage he saw along the way.

said so, but Xia Mu was still not at ease in his heart, and summoned the Black Iron Divine Armor Protector.

The more he moved forward, the more puppet remains he encountered, and the level became higher and higher, and each of them seemed to have the combat power of the immortal realm, but unfortunately, all the internal runes were destroyed and could not be activated.

"I don't know if these puppets are still in danger of being repaired. ”

Xia Mu looked at the huge puppet remains scattered around him, and was about to take away some for future use, when suddenly, a low sound suddenly came from not far away, and it was getting closer and closer, and in an instant, it seemed to be galloping from an extremely far away place from Xia Mu to a distance of only dozens of zhang from him.

This made him change color, and when he looked at it suddenly, he immediately saw a huge shadow appear more than twenty feet away not far away, and if he didn't look closely, he thought it was a steep mountain cliff.

At this time, the huge shadow eyes lit up, and a strong fierce aura was overwhelming, turning into a strong wind blowing in the face, and when it was approaching, on the back of Xia Mu's hand, the brand of nightshade suddenly flashed faintly, just like this, but the shadow that was about to make a move on Xia Mu stopped.

The shadow stared at Xia Mu for half a cup of tea, and finally let out a long howl, quickly retreated, and disappeared into the darkness after a few flashes.

Xia Mu couldn't help but let out a drop of cold sweat on his forehead, and the shadow just now gave him the feeling that it was dozens or hundreds of times more dangerous than the demon killing general and others, like a powerhouse in the immortal realm high above.

"Could it be that this is a puppet with the combat power of the immortal realm?" Xia Mu guessed in his heart, hesitated for a moment, and continued to climb forward carefully, walking all the way for about half an hour, Xia Mu was frightened step by step, because along the way he encountered seven puppets one after another, each of which was not weaker than the one he encountered before.

It's just that every time these puppets just pounce on him, they retreat inexplicably, which makes him very puzzled, but he is also a lot more relieved in his heart, at least it doesn't seem to be dangerous, right?

"Could it be that the monks of all races who entered the abyss of the blue sea in the past were all killed by these guys?" Xia Mu looked at the retreating figures and fell into deep thought, if this was the case, then why did he come all the way unharmed.

As a result, before Xia Mu could figure it out, a corpse appeared in front of him, it was a man, but his body had been destroyed, and it was more appropriate to describe it as a corpse.

"This token...... It's the cultivation of the water hell. After some checking, Xia Mu groped for a blue token on the man's waist, which was the identity certificate representing the seven-colored Hell Water Hell line, but the token was already a little broken, and the spirit was fading, and I don't know how long this person has been dead here.

Taking off the Qiankun ring from the man's finger, Xia Mu opened it and looked at it, almost blinded by the crystal light in it.

"It's... This is ......" Xia Mu muttered to himself, in his divine exploration, there is a mountain in the Qiankun Ring of this Water Hell Man, this mountain is hundreds of zhang high, if it is just an ordinary mountain, it will naturally not let Xia Mu be like this, but this mountain in the Qiankun Ring is a ...... A mine made up of Aoi Mine Rock!

Countless Aoi Mine Rocks are piled up together to form a Aoi Mine Rock Mountain!

The combined value of the treasures that Xia Mu had harvested in the Great Blue Sea Tide before was not as good as the Kwai Water Thunder Rock Mountain in front of him, and with this Kwai Water Thunder Rock Mountain as the center, there were still some various things scattered in all directions, including spirit treasures, pills, and spirit runes, the number was enough to be comparable to the net worth of an immortal realm monk.

Taking a deep breath, Xia Mu tried to calm down the restless mood in his heart, and then put away the Qiankun Ring and continued to check if there were any other storage utensils on the water prison man.

But it's a pity that Xia Mu didn't have any gains except for the Qiankun ring before, but this also made him so satisfied that he couldn't be more satisfied, a mine composed entirely of Kwai Shui Lei Rock, the value is simply not too high.

After packing up his mood, Xia Mu continued on the road.

When he continued to climb along the stone wall for three thousand zhang, the gravity around him changed again, originally Xia Mu was hanging on the cliff wall to climb, but as soon as the gravity changed, it became him lying on the ground and prostrating.

"Annoying!" muttered, Xia Mu stood up from the cliff wall and walked forward on foot, the speed was much faster than the previous climb.

Taking advantage of the change in gravity, he put aside everything else and walked forward quickly.

6,000 zhang, 9,000 zhang......

Time passed minute by minute, and Xia Mu went deep for another hundred and three thousand zhang, but it still did not come to an end.

"How big is this blue sea abyss?" Xia Mu's heart was awe-inspiring.

But at this moment, there was actually a treasure light emitting in front of him, it was a spirit grass as bright as a spar, and around this spirit grass, the void was twisted from time to time due to being affected.

"Space-time grass!"

Xia Mu exclaimed, the space-time grass is an extremely special spirit grass, it was born in the void and grew up in the void, no one can find it in eternity, only after it matures, it will automatically break away from the void and appear in the outside world, and in this process, the space-time grass will seal the time that occurs within a few miles of its growth range, once someone is inspired by spiritual power, then everything that happened in the past time sealed in the space-time grass will evolve again.

"Interesting, did the owner of this Thousand Machines Hall want to tell future generations what he planted this space-time grass back then?" Xia Mu guessed in his heart, and felt more and more that there must have been some unknown secret that happened in this blue sea abyss back then.

Without thinking about it, Xia Mu stepped forward directly and transported a wisp of spiritual power in his body into the space-time grass.

Soon, in the center of this space-time grass, a small white flower slowly grew out, and in the process of its growth, images continued to emerge in the void.

It was a seriously injured old man, who was sitting on the shoulders of a tall puppet, fleeing towards the depths of the blue sea abyss at great speed, in the process, the old man kept throwing round spheres in his hands, and these spheres were thrown out at the moment with the sound of the machine, and they all turned into a concrete tall puppet, firmly guarding the passage to the depths of the blue sea abyss.

After doing all this, the old man drove the puppet and disappeared into the depths of the blue sea abyss.

Not long after the old man left, a young man with a gloomy face arrived.

Xia Mu could see clearly, the man with a gloomy face seemed to know the weaknesses of these puppets extremely well, and almost effortlessly destroyed all the puppets holding the passage.

Then, the man hurried in the direction that the old man had fled, and then disappeared into the depths of the blue sea abyss.

After the old man and the man left one after another, no one else passed by here, and it was not until a long time later that the young man walked out of the depths of the blue sea abyss with serious injuries, and after him, the old man who entered first never came out again, and was suspected to have died at the hands of the young man.

Since then, no one has passed through this place, but the puppets that were released by the old man and then destroyed by the man have resumed their operations after a long period of self-repair, while the rest have been destroyed forever and can no longer move.

Xia Mu stared at the images that evolved from the space-time grass, and until the end, he didn't find that the old man had walked out of the abyss of the blue sea.

"Is it really dead inside?" Xia Mu thought, judging from everything that happened in the previous video, the old man probably died at the hands of the man.

It's just that who of these two people is the master of this Thousand Machine Palace?

Xia Mu was puzzled.
