On the solid stone plain of the main material plane, in the endless solid stone plain, a large hole appeared somewhere, and this big hole went vertically, and I don't know how deep it led to the ground.

Around the big cave, countless skeletons are busy, they are constantly transporting the soil in the cave day and night, and the hole with a diameter of four or five meters has dug up several dirt mountains.

Two hundred kilometers underground, a giant sandworm is struggling forward, and the hard rock is no different from tofu under its mouthful of sharp teeth.

As a giant creature in the Demon Abyss, the energy level of the giant sandworm is actually not high, and it can still pass through the abyss passage, if it can't pass through, it will be good to starve it for a few days.

After the giant sandworm that had been hungry and thin for several laps came to the main material plane, he ate and drank for a few days, and then he was full of energy and devoted himself to the hard work of burrowing.

With its help, the millions of skeletons under Luo Qiu's command spent more than three months digging a super long cave that went straight to the depths of the earth.

In the past, although Luo Qiu knew that the Infinite Spider Mother died on the main material plane, he had no intention of digging a hole in the ground at all, first, he was limited by the experience of his previous life, and thought that it was impossible to make a hole that was too long under the current level of technology.

In the previous life, a certain bear country once drilled a hole more than 12,000 meters deep, and it was difficult to continue, the underground situation was too complicated, and it was more difficult to penetrate it than on Mars.

Secondly, he didn't even know where the Mother of Infinite Spider died, he didn't know the specific location, and he didn't know where to burrow.

These questions had all been answered from the moment Luo Qiu saw that face in the void.

Mother Infinite Spider is not where she died, but it is the foundation of the main material plane, this plane is built on its corpse, no matter where you make a hole, you can hit the body of Mother Infinite Spider.

However, Luo Qiu still specially selected the Solid Stone Plain, because after investigation, the geological conditions of the Solid Stone Plain are the most stable, at least there is no need to worry about the collapse of the cave halfway through.

Secondly, the underground situation here is not complicated at all, in the previous life, there were soil layers, rock layers, permeable layers, crust, mantle and so on distribution, and the temperature and humidity were also inconsistent, but here, it is possible to penetrate the entire underground, and there is only one rock layer.

As soon as he saw that face in the void, Luo Qiu decided to make a hole, and directly remotely commanded Gray and Klotina, who remained in the main material plane, to start preparing, and even transferred the giant sandworm over.

After three or four months of painstaking excavation, the giant sand stone and a large number of space magicians, earth magicians, and millions of skeletons dug out an ultra-deep hole with a diameter of three to four meters and a depth of one hundred and thirty kilometers, which was something that was unimaginable in the previous life.

The giant sandworm has a very comfortable life, and has meat to eat every day, but what it really needs is not pure meat, protein is only a part of the substances that make up its body, and it also has cartilage, cortex, high-strength support structures, etc., eating meat alone cannot meet its nutritional needs.

In the same way, it is not enough to just eat magic crystals, it needs a reasonable nutritional match.

In this regard, Margaret is the most experienced, since Luo Qiu gave her the concept of nutrition, she is simply fascinated, over the years, she has become the most amazing nutrition master, concocting thousands of different nutritional potions or foods, such as slimming meal replacement powder, skin beauty powder, moisturizing nail powder and the like.

After her own nutritional formula, which includes protein, calcium, trace elements, earth-based magic crystal powder, and defensive paint particles, etc., the giant sandworm was fed white and fat, and evolved a lot of new characteristics.

The first is the growth in size, which is twice as long as before and three laps fatter.

The second is that the telescopic ability is getting stronger and stronger, now it can shrink into a fat sandworm with a diameter of six meters, or it can be stretched into a slender worm with a diameter of two meters, and it can be stretched freely, and it can dig a hole with a diameter of two meters, and it can also dig a hole with a diameter of six meters, which is simply a shield machine of any size.

At the same time, its skin also grows crust-like bumps, which not only enhance its defense, but also reduce its friction in the formation, making it move more smoothly.

And then, there's its sharp teeth.

Sometimes I really have to admire the creatures of this world, the body parts they have evolved are even stronger than the performance of the industrial products in the previous life, and the defensive carapace that Luo Qiu's Cave Wind Bow is difficult to shoot through, those particles are crushed by it as soon as it chews it, and the rocks in the ground are naturally even more useless.

Every day of hard digging holes, every day there is a delicious nutritious meal, a bite of the giant sandworm's sharp teeth become more and more sharp, whether it is a rock or an ore, all bite into pieces.

But its invincible sharp teeth suddenly bit something, and dozens of them snapped off with a click.

It wasn't until the giant sandworm cleared the surrounding rocks that everyone still couldn't see the whole picture of this thing, and could only roughly see that it was a protrusion from some kind of giant creature.

Gray and Klotina glanced at each other, and couldn't help but show ecstatic expressions: "The corpse of the Infinite Spider Mother, found." ”

......

The bone fortress, Luo Qiu's life box burst into flames, and the throne made of bones suddenly collapsed, and all the bones instantly turned into powder, but they gathered under the kneading of an invisible big hand, and quickly pieced together a new golden skeleton.

The bones that were pieced together into the throne had long been metalized under the tempering of Luo Qiu's life box over the years, and the skeleton that was shattered and condensed was also gold-level.

The life box slowly moved into the skull of the skeleton, and after standing still for a while, purple soul flames rose from the hollow eye sockets.

Luo Qiu was in another plane set, and it was very difficult to teleport back, so he could only temporarily let the body move, before, because the body did not have a suitable body, those ordinary skeletons could not carry his soul. But after more than ten years of research, Luo Qiu has learned the ability to crush and reassemble bones, just like his hands and right leg.

However, one soul can't control two bodies, and as soon as Luo Qiu's body moves, the body far away in the yellow sand plane falls into a static state.

Rushing to the rocky plain as fast as possible, Luo Qiu rushed to the cave, and jumped in without saying hello.

"Your Majesty, there is a teleportation array here, more than 200 kilometers deep, if you jump like this, it will take two or three hours to fall to the end. The Sith on the side hurriedly called.

Behind Luo Qiu, a stream of flames erupted, and he flew out of the cave again, flying towards the teleportation array. A dazzling light flashed, and Luo Qiu was already two hundred kilometers deep underground, where a huge space had been gnawed out by giant sandworms.

On one side of the space was an irregular rock wall that had been gnawed, and on the other side was something with regular protrusions on the surface, like the surface carapace of some kind of giant creature, and as soon as it came out of the teleportation, Luo Qiu's body in the other plane set, the dominant hands on his hands and feet trembled slightly.
