The reason why the system did not find it before is probably because during the operation of the puppet, a protective energy will be generated, which will continuously supply the shell of the heart, thus producing a strong shielding effect, and as the puppet stops, the heart naturally loses its energy supply, and is discovered by the system.

Xiao Ran looked left and right, but still couldn't see why. If it were placed on a street stall, it would definitely be treated as a larger handicraft.

However, Xiao Ran still subconsciously leaned out his soul power to enter it, this time there was no limit, Xiao Ran's soul power directly entered it.

After a long time, Xiao Ran slowly opened his eyes and exhaled a long breath.

"So it's a key!"

Just now, Xiao Ran's soul power seemed to be in a void of darkness the moment he entered this cuboid. But soon, in this dark space, lines with bright light appeared, and as these lines with light continued to outline, something similar to a map finally appeared, Xiao Ran could see that this map should belong to Pluto, and the end point of the map should be an ancient ruin, as for this cuboid is the key to open the ancient ruins.

Xiao Ran returned to the mecha, checked it roughly, and found that the place hit by the puppet was no longer very easy, and it was probably difficult to send a distress signal.

Xiao Ran glanced around, and finally stopped on a mountain peak.

If you wait until Li Yangyi and the others come over, I'm afraid it will be a few hours later, this is not the earth, their mission this time is time-limited, once it exceeds this time, it doesn't matter to them, but the oxygen inside Li Yangyi and the others' mecha will be gone, and it will be difficult to return to the earth at that time.

Xiao Ran thought for a while, and then decided to go it alone first. After all, I don't know what is in this ancient ruins, if you drive the mecha in, I'm afraid it will be extremely inconvenient, and Xiao Ran can get out of the mecha, which gives him a lot of flexibility, and he is so flexible in the ancient ruins.

However, before that, Xiao Ran still planned to make some marks to save Li Yangyi from worrying about them.

Xiao Ran pulled out the golden dragon thunder words, and immediately one after another sword qi flew out, accurately landing on the mountain not far away, and suddenly countless rocks on the mountain splashed, scattered in the vacuum, and drifted into the distance.

Ten minutes later, Xiao Ran finally put away the knife.

He stared at the handwriting he carved on the mountain and frowned a little, to be honest, it was indeed a little ugly, after all, lettering is a handicraft, and he can't do it himself, but he can recognize it.

There is a very simple sentence engraved on it, I will go first, if you don't return for ten hours, you go first.

Xiao Ran glanced at the font, nodded with satisfaction, and then left here directly.

He planned to go alone under the protection of the system, as for the Immortal Great Wall, Xiao Ran planned to stay here, firstly, there was a location in the Immortal Great Wall, and Li Yangyi could find it when the time came, and secondly, to avoid unnecessary energy loss.

About half an hour later, Xiao Ran appeared in a mountain range, these mountains were not very high, but they stretched endlessly, at least for thousands of miles.

Xiao Ran recalled the map, the entrance to this ancient ruin should be nearby.

Immediately, the system began to monitor everything around it, and soon locked on to a target.

It was a valley, and the bottom of the valley was an extremely long belt of ice.

Xiao Ran jumped directly off a peak and rushed in that direction.

After landing, Xiao Ran simply and rudely stabbed into the ice belt, and immediately the cosmic energy in his body frantically poured into the blade, and suddenly an extremely powerful energy began to spread under the ice belt.

"Broken!"

Suddenly, that cosmic energy broke through the ice and directly tore through the ice belt of dozens of meters.

Xiao Ran plunged the blade into a crack and swung it hard, shattering the rock.

It wasn't until Xiao Ran stabbed something solid that he stopped, and after cleaning up the surroundings, Xiao Ran saw a silver surface, and he knew that this entrance must be here.

This is a surface layer made of a special metal, extremely hard, even a human thermal weapon bombardment can hardly destroy half a point, and in the center of this layer of silver surface there is a depression, the size is exactly the same as the cuboid in Xiao Ran's hand.

Xiao Ran directly stuffed the cuboid into it, and with the embedding of the cuboid, it directly merged with the silver surface, and there was no gap at all.

Xiao Ran took a few steps back, just in case there were any other mechanisms or anything like that.

A few seconds later, a silver light burst out from where the cuboid was embedded, and the light shot into the sky, and in an instant, silver textures began to spread from all directions, and the rocks and ice belts were directly torn apart in their passes.

After more than ten minutes, there was no longer a single rock at the bottom of the entire valley, Xiao Ran looked at the floating rocks and broken ice, and frowned slightly.

At this moment, a huge entrance appeared in front of Xiao Ran, he was actually a little overwhelmed in his heart, this ancient ruin was obviously established by a higher existence than the currently known civilization of mankind, if there was any danger in it, I am afraid that it would be really difficult for him to resist.

But after some mental struggle, Xiao Ran gritted his teeth and rushed directly into the entrance.

As Xiao Ran entered, the entrance closed instantly, and the surrounding free rocks seemed to be attracted by something, and instantly covered the entire valley floor again.

After Xiao Ran stepped in, he found that in front of him was a wide corridor, and there were many huge silver doors around the corridor.

Xiao Ran was very careful in every step, after the soul power was completely ineffective, only the system was constantly scanning the surroundings, although the scanning of the system showed that there was no danger, but Xiao Ran did not dare to relax his vigilance.

He paused as he walked to a doorway, because according to the system's prompts, there seemed to be something inside.

Facing the silver giant gate that was more than ten meters high, Xiao Ran didn't know what to do, and just when he was panicking, suddenly a pillar of light fell from the top of this corridor without warning, instantly enveloping Xiao Ran.

Just as Xiao Ran was about to rush out, a green light suddenly lit up on the silver giant door with a pale face, and then the huge silver giant door slowly opened.

Xiao Ran watched the moment the silver giant door slowly opened, the whole person was in a state of extreme vigilance, and even the golden dragon thunder in his hand had already flashed a layer of blue thunder and lightning, as long as there was any danger, Xiao Ran could guarantee to shoot as quickly as possible.

But as Xiao Ran's vision widened, he was suddenly stunned.

There was no danger in front of him, this was clearly an arsenal.

Xiao Ran walked in in shock, he walked to a transparent cabinet, his footsteps stopped, looking at something similar to a firearm inside, Xiao Ran couldn't help but reach out and take it out.

He looked closely, but he was still confused.

"How is this thing firing!"

Xiao Ran tossed it casually, but suddenly pressed a place, and in an instant, a laser shot out, immediately shooting through a small hole more than ten centimeters deep on the ground where Xiao Ran's muzzle was pointed.

Although this firearm does not have extremely strong explosion damage, Xiao Ran knows how hard this silver floor is, and it is naturally needless to say that it can shoot a small hole into such a floor.

"So powerful?!"

After a brief moment of shock, he put the gun back in place and continued to walk forward, discovering that the level of technology of the weapons here was far beyond that of the earth, and it would take humans at least thousands of years to develop to reach this level.

The entire arsenal is about 2,000 square meters, and although there are not many weapons, these weapons have brought mankind far and a half of progress, and by analyzing the construction of these weapons, mankind will be able to replicate exactly the same thing.

At the end, Xiao Ran found a staircase, so Xiao Ran walked down the staircase.

The bottom is wider than the top, and the moment Xiao Ran went down, the huge field below directly lit up.

Although there are some weapons here, most of them are some weapons that have been scrapped, here Xiao Ran also saw two broken small combat aircraft, Xiao Ran found that there were many scattered parts around the two aircraft, it seems that there was a war here back then, and these two flying instruments should have been damaged a lot, stay here to wait for repair, but in the end there was no time to repair.

Although I don't know how many thousands of years have passed here, there is not the slightest trace of dust.

Xiao Ran walked in front of an electronic instrument, hesitated in front of the huge display screen, and even if he planned to turn it on, he still gave up after tossing for a long time, maybe this instrument should have broken down a long time ago.

When Xiao Ran picked up something, out of the corner of his eye, he caught a glimpse of a huge glass tube not far away, in which a battle armor was placed.

Xiao Ran's eyes lit up suddenly, and he walked over directly.

This pair of armor looks similar to what he is wearing, but the details are more exquisite, and Xiao Ran is even more happy after passing the scanning of the system, because all aspects of this armor are a hundred times more powerful than what he is wearing, even in the face of the previous particle nuclear bomb, I am afraid it can resist.

Xiao Ran looked at this pair of battle armor, his eyes full of longing.
