Shen Lang stayed for two more days, confirming that Bi Haihuan had a better understanding of her strength at the peak of the Void Realm, as well as a better understanding of the study of spells and so on, before leaving Menglu's military sub-domain.

The last time she came, it was Bi Haihuan who gave the positioning to Feng Yuegu, and this time, it was she who personally piloted the spaceship and sent Shen Lang back to the forest.

It was not difficult for Shen Lang to find that area in the basin city-state by himself, but it was a primeval forest as large as I don't know how many countries, and it was impossible to be accurate to the point of the billions of ring arrays.

If you want to search it out slowly, even if you can do it, it will be a long time for you to know how long. Fortunately, their positioning was very accurate, and Bi Haihuan drove the spaceship over directly according to the point where he picked him up for the first time.

After saying goodbye to Bi Haihuan, watching the spaceship disappear into the sky, Shen Lang did not stop and rushed back to the billions of rings.

The place where Feng Yuegu picked him up, the distance from the entrance of the teleportation formation was also a little distance, and at that time, he thought that he could not alarm the Nanliu River and the South Flowing Water that cut the iron armor red dragon skin.

And where they are in the Iron Armor Red Dragon, they are still quite far from the entrance.

However, this is reduced to a range of tens of miles, and it is nothing, and you will not get lost in the place you have walked through.

Walking back again, he passed the place where the ironclad red dragon was, and saw that what was left there was a large skeleton.

He had only been away for a little more than a month, and normally, it was impossible for such a small Roshan to rot so quickly, let alone turn into white bones.

The skin, tendons or something, it should be Nanliuchuan They got it, the blood was drained by him, and the rest is considered jerky, which is said to be able to stay for a longer time.

Nanliuchuan shouldn't have that much space to move everything away, and the excess skin and flesh should have been eaten by other fierce beasts in the forest.

Shen Lang took a brief look and prepared to leave.

But immediately the eyes stayed on the ground beneath the skeleton.

There, he saw a somewhat familiar stone.

Back then, in the Forest of Death, the golden mastiff guarded by Count Dracula was prostrate on top of one of these fire crystals, lurking in a cave to absorb cultivation.

Now there is also one such stone here, not necessarily exactly the same, but still similar.

Shen Lang was a little puzzled, when they came here, they were attacked by the Iron Armor Red Dragon, the scene has not changed, the traces of the destruction by the Iron Armor Red Dragon and him around them, those big trees that broke and burned the crown, can be proved.

At that time, it was certain that there was no such stone at the scene, otherwise even if he was negligent, it would be impossible for them to be negligent in Nanliuchuan, who was bent on treasure hunting.

So why did this thing appear a month later?

It can't be out of nowhere, and it can't be that a ferocious beast is here.

Shen Lang carefully identified the specific position, and then compared the skeletons, and had a guess that might be more reliable.

This stone should have been in the body of the Iron Armored Red Dragon!

At that time, according to the ancient records of the Iron Armor Red Dragon, Shen Lang said that there would be a special spiritual spring like "molten iron magma" nearby, so that it would evolve into this way.

Now it seems that this is the reason for this!

This fire crystal is of great benefit to their kind, but the Golden Mastiff is still not ranked, just crawling and absorbing at close range, while the Iron Armored Red Dragon can directly devour and absorb slowly.

After feeling it, this fire spar was also more restrained, just like those Inner Dan that had been collected for decades in the city-states of the river basin, there was no such intense energy overflow, so he almost missed it just now.

When they killed the Iron Armored Red Dragon that day, including when they skinned and cut their internal organs, they were all covered by the powerful aura of the Iron Armored Red Dragon itself, and they didn't find this. I think it was eaten up by other beasts or carnivores, and then the fire crystal fell to the ground under the skeleton.

Shen Lang couldn't help but laugh, this should be considered a very valuable one, but the Nanliuchuan brothers have been busy for a long time, and they still missed it close at hand.

But that's just the surface, and there's a lot of energy there's still there.

After collecting it, Shen Lang was afraid that he would miss anything again, so he spent a little more time examining the skeleton of the iron-armored red dragon from beginning to end to make sure that there was nothing else valuable.

Of course, this value is a rare and valuable value, otherwise, its dried flesh and its bones can be exchanged for spirit stones when they are returned.

It's just that it's too huge, and he doesn't have more space to carry these big bones.

Continuing to walk back along the way he came, and then positioning himself through the towering tree that had been cut into a flagpole, Shen Lang returned to the entrance of the Billions Ring Array.

In the past month or so, he has really lived in another world, and he has experienced other people's technology, war, and civilization, etc., and it is still a little embarrassing to come back.

Shen Lang hesitated for a moment, wanting to leave a few words for Bi Haihuan with the Holy Armor, but after thinking about it, forget it. She was now piloting the spaceship back, and she had already said goodbye, and any more procrastination would make her even more sad.

This is not a spatial teleportation array, but a natural spatial rift. I don't know when and who arranged the billions of rings, just to hide this crack.

Although Shen Lang is alone now, there is still no problem in solving the hundreds of millions of ring arrays.

In fact, without Nanliu beside him, he could be even faster. Because you don't need to prove anything like the half-believing Nanliushui, you don't need to explain, or you don't need to be afraid of being stolen.

Ring by ring, ring by ring, ring-by-ring.

Walking to the back, Shen Lang admired this senior very much.

Because this is not a billions of rings, but there are billions of rings on both sides, or on the edge of the spatial crack, the whole project is bound to be huge, and the difficulty is also very great.

When he came out of the last ring, Shen Lang once again arrived in the huge pit in the belly of the mountain.

Although it is still a bit rough to get out of here, it also means that there is no mistake in returning the same way.

Flying up in the huge pit, he found the small crack from the mountain wall, and Shen Lang walked back along the crack.

Walk all the way to the gap that is blocked by the stone wall.

When they came, it was a mechanism opened by Nanliu outside, and they should have gone out from here when they went back.

However, Shen Lang used the glowing stone of the Ice Palace to illuminate it, and searched for it, but he didn't find any mechanism in the cracks of the stone wall that he downloaded!

This made him sweat a little, and at that time because everyone was together, he didn't think that he would be separated. And it is also natural to think that since there is an organ to enter, there must also be an organ to go out.

Undeterred, though, he returned to the crater and searched the surrounding mountain walls. The predecessor designed such a huge project, and hid the entrance so deeply, maybe he also arranged another exit and hid it tightly.

In this way, even if someone gets the news and looks for it, if they can't crack the billions of rings, they can't go out again to avoid the leakage of more information!

But the Nantian family obviously knows the way to get out, and Nanliu Chuan Nanliushui has been here more than once.
