After more than three laps around the subterranean space, there was almost nothing but flat rocky ground.

The only thing worth mentioning is that in the very center of the underground space, there is a small pool.

The pool is quite small in size, and it can't even accommodate the size of the Flower Jackal King.

Suddenly, Xiaoqing came to the side of the pool and roared at the pool.

Gu Chuchu moved, staring at the only foreign object in this underground space, and said to the Black Rhino Patriarch: "Brother Heiwei, please destroy this pool, Xiaoqing feels that there should be something underneath." ”

"Okay!" the black rhino patriarch agreed, took out the giant axe from his back, stepped forward a few steps, and slashed the axe into the pool, and suddenly there was a rumbling sound of the rocks being shocked, and the water in the pool was even more splashed.

After the black rhino patriarch took an axe, he did not continue to chop, but looked at the pool in front of him and said in surprise: "Listening to this voice, it is indeed empty below. ”

"Since it's empty, according to the message from Xiaoqing, the pearl wolves are likely to be down here, but I don't know how they got down. "Gu Chu secretly said, the pool in front of him was still intact after withstanding the blow of the Black Rhino Patriarch, and the water in the pool did not seep down.

From this point of view, even if the pearl wolves are really under the pool as Xiaoqing said, then there must be a secret passage here that the ancient people do not know, and those pearl wolves must have gone down to the depths of the ground through the dark tunnel.

"Okay, then I'll continue chopping!" the Black Rhino Patriarch straightened his waist, raised his axe high, and with a loud shout, he directly smashed the pool completely.

"Boom!"

The pool, along with the rocky floor with a radius of tens of meters, collapsed violently, and the flat rocky floor under the feet of Gu Chu and the others immediately shattered into countless rubble, and together with them, they all fell deep into the ground.

"I didn't expect that there is still a layer of space here!" Soon, Gu Chu and the others landed safely, their physical fitness was far beyond ordinary people, and the height of this fall was only more than ten meters, and it couldn't hurt them at all.

As soon as Gu Chu landed, he looked up into the sky, and as far as he could see, there was a smooth natural rock ceiling, and there was a huge hole in the ceiling, through which he could see the rock ceiling on the next level, and Gu Chu knew that it was the first underground space they had reached through the passage.

"Since there is a second layer, the creation of heaven and earth is really amazing!" Gu Chu exclaimed, and placed his vision from the cave above on the surrounding scenery.

The underground space of this second layer is extremely vast, and it is roughly estimated that it is at least several times larger than the space of the first layer, like a huge square.

However, he also found that this place was still the same as the first floor, except for the vastness, there was nothing, and in the middle of the space, there was still a pool, and the water in it was quite scarce.

"Black Rhino Patriarch!"

"Got it!"

The Black Rhino Patriarch broke the pool again, and the ground shattered, and the place where Gu Chu and the others were standing collapsed with a bang, and fell into the third layer of underground space again.

Third floor!

At this point, Gu Chu's eyesight couldn't see how big this underground space was, but it was certain that if Gu Chu couldn't see the end, the space here would definitely be several times larger than the second layer!

"The first floor is only the size of a few football fields, the space of the second floor is almost five or six times that of the first floor, so the space of the third floor is five or six times the size of the second floor, so isn't the space of the next floor several times larger than this floor?"

Gu Chu was full of thoughts, and at the same time, he focused his gaze on the center of the space.

There, there is still a pool, but the pool here is much larger than the two floors above, and there is a lot of water stored in it, so it can be regarded as a reservoir.

After the black rhino patriarch finished exploring the cistern, he said to Gu Chu: "Gu Chu, that's right, there is another layer below this!"

"Don't worry, let's go around here and search for resources or creatures in this space. "Ancient Chu Dao.

Everyone rode up to the wolf king and circled around the vast space, and found that it was still the same as the upper floors, with nothing but the pool in the middle leading to the next floor.

"Gu Chu, do we still want to go down? Don't you think this place is a little weird?" Hong Qingling opened her mouth at this moment, her pretty face changed slightly, she was quite resistant to this underground space.

"One layer down, one layer down, the ground on the upper floor is the ceiling of this floor, so vast that there are no pillars, but it won't fall, this world is amazing!" Gu Chu sighed as he looked at the pool.

"Of course you have to go down, such a wonderful place, how can you not explore it?The pearl wolves are undoubtedly in which layer of space below, since the pearl wolves exist, then there must be other beasts that exist underground, among which there must be many cherished beasts, if so, this is equivalent to a treasure land!"

"However, if we are attacked by a herd of beasts, how are we going to go up?" Hong Qingling looked up slightly worried as he looked up at the big hole in the ceiling, which was originally the place where the upper layer of the pool was located, "I can use secret magic to fly, but I can't bring so many people in a short period of time." ”

Indeed, among the people in the cave, in addition to Gu Chu, Hong Qingling, and the Black Rhino Patriarch, there were more than a dozen greedy wolves and the elders of the Black Rhino tribe, as well as a group of wolf kings.

The top combat power of the greedy wolf alliance has almost all followed the ancient early into the underground exploration.

On the ground, there were only two clan elders and two hundred wolf kings, as well as a group of camel wolves as guards.

Gu Chu smiled and patted Hong Qingling's shoulder, and comforted: "Don't worry, the people in our tribe hunt all year round, and the clan elders all have ropes on their bodies, and this is just a dozen meters high, just throw the rope." ”

With that, an old man of the Black Rhino Clan picked up a stone, wrapped a loop of straw rope around it, and threw it through a large hole in the ceiling to the ground on the previous floor.

The straw rope was precisely wound around a raised stone, and the old black rhino pulled the straw rope, feeling quite stable, so he let the straw rope be placed here as the way back.

Seeing that the clan elder was so professional, the worry in Hong Qingling's heart immediately disappeared.

Gu Chu smiled in his heart, he could see that Hong Qingling was not worried about how to go back at the moment, or the beasts underground, those with Hong Qingling's combat power were enough to deal with easily.

She's just scared of the darkness around her.

However, these have not been broken at the beginning of ancient times.

"Boom!"

The cistern was broken, and the crowd descended one level again.

"This fourth layer is a little different. Gu Chu looked around at the situation, and a slight glint flashed in his eyes.

The surrounding space is still very vast, and it is not appropriate to say that it is an underground space, but it has a feeling of being like an underground world.

On top of that, there are creatures in the vast fourth layer.

A little bit of spark, existing in the fourth layer, constantly floating up and down, emitting a faint incandescent white shimmer, the fireflies in the fourth layer are almost everywhere, and every few steps there is a ball of fireflies constantly flying, making the world of this layer light up.
