For what Xia Yu said, Fourteen Niang's short experience of more than 200 years is still a little incomprehensible, but this does not prevent her from standing on the same front with her brother, and if her brother wants to build a big house underground, it will be built.

In the past, she had also seen a lot of little foxes living in the caves, to be honest, she was born to be a monster, so she never lived in the cave, and it seems that she will live in the cave with her brother in the future.

A good underground base is understood by Fourteen Niang as a hole where ordinary foxes live, and the base will definitely be angry.

But both men are on the move. After the Five Elements Earth Escape, Xia Yu finally felt what it was like to be like a fish in water, diving, diving, diving, the water pressure is getting deeper and bigger, and the same is true for land, and the pressure may be even greater.

Fortunately, Xia Yu used a spell, not just going straight down, so it was protected by a light film, but Xia Yu could also feel that the deeper it was, the greater the consumption of true qi, maybe if he didn't leave a little true qi to go back, Xia Yu couldn't break through the crust on a one-way underground trip.

However, it doesn't need to be so deep, even if you want to use geothermal energy, Xia Yu needs to find only a lava through layer. However, Xia Yu believes that his base should be able to use the latest energy, and to hell with the old forms of energy utilization!

So after diving a few kilometers, Xia Yu also changed the direction and swam to the front, with such a spell, it should be easier for Xia Yu to rob the tomb, rammed earth layer, the tomb wall is directly worn by you, and what kind of robbery hole.

I remember that I almost drew a tomb robbery specialization before.,In case you get it, it's the same as this ability.,As for what can steal the tomb of aliens, it's definitely going to eat skill improvement coins.,It's impossible for you to ascend to the sky in one step.,But the existence of this similar skill point is not good.。

However, this is the Maple Leaf Country, where it is like in China, you can dig out the tomb by digging it casually, so Xia Yu didn't see any tombs along the way, but there are a lot of fossils, like a dozen meters long Canglong fossil or something.

But just like the memory of the mobile phone is getting bigger and bigger, it is still not enough, Xia Yu's newly upgraded 256 cubic meters of space can't even fit such a dinosaur fossil, otherwise Xia Yu has to get it back.

In fact, Xia Yu has always had a question, why does this storage space eat points so much, is it that the author Jun wants to use this to consume the points he earned back with his life, but after thinking about it, how is this possible, for the dimension, maintaining the space is actually a very energy-consuming thing, maybe things like storage rings in the Xianxia film and television world are likely to fail when traveling through time and space.

Fortunately, although the price of storage space is also rising, it is still growing by geometric multiples, so it is worth it.

Pretending to have a true qi slot, no, the true qi trough is almost empty, and you must go up immediately.

"Whew~~" Spit out the oxygen plug in his mouth, Xia Yu breathed a breath of fresh air, there is still air supply in the earth at a depth of dozens of meters, and then you will use the turtle breath technique, but is Xia Yu the person who uses the turtle breath technique to pretend to be a turtle at every turn?

Fortunately, there is still a lot of oxygen prepared for emergencies in the space, and Xia Yu can breathe, but the pure oxygen liquefied and stored for a long time is still not as good as the fresh air in this wasteland. After holding it for more than five hours, Xia Yu still came up.

But I still haven't found it.,The crust here is so hard.,It's not ideal for building a base at all.,This area is directly hit on the electronic map.。

Xia Yu ate something and began to recover his true qi, although the amount of true qi in the real world will not increase, but the consumed true qi can still be replenished by carrying Zhou Tian, of course, Xia Yu also has the three Hui Qi pills given by Xu Fu, but that is reserved for the battle, so it is better to recover slowly in this situation!

"Brother~~Brother~~" A few hours later, Xia Yu heard the extremely eager voice of Fourteen Niang coming from a distance.

What's wrong? When he opened his eyes, Xia Yu saw Fourteen Niang flying towards him, her beautiful little clothes and her face and hands were full of mud, but she was still very cute.

"Brother, I have made a major discovery, come with me." Before Fourteen Niang finished speaking, she flew in the direction she came from, without even touching the ground.

Got it hard to find a place? With such an idea, Xia Yu also chased towards Fourteen Niang, we can't fly, and we still run very fast.

But after a while, Xia Yu still called Fourteen Niang down with a "phone", it was too bullying, if you don't fly with someone, you will soar to two or three hundred yards, and the effect of running out of the five-gear electric fan on two legs can't catch up, Fourteen Niang is also a little embarrassed, smirking like grabbing a puppy's neck and flying Xia Yu up.

Even so, Fourteen Niang flew out more than 200 kilometers and went directly to the most marginal part of the area that Xia Yu had drawn for her.

"Brother, this is it." They landed in front of a hole.

"Fourteen Niang, you dug this hole?" There was shock in Xia Yu's voice.

"Well, brother, I dug it, didn't I dig it well?" Tilting her head, Fourteen Niang was a little puzzled.

"No, it's just too good to dig." Looking at this hole that is comparable to the surface that has been poured with concrete, Xia Yu doesn't know what else to say, it seems that the most suitable type of soldier for Fourteen Niang should be sappers, and Xia Yu is embarrassed to say that he is an engineer in this regard.

"Thank you, brother, the soil will always fall off when I dig, so I fixed it with a little mana." Fourteen Niang was embarrassed to touch her head, these were all things she did very instinctively, as if she knew about it in her previous life.

Fixed with mana? It turns out that mana still has such an effect, and it seems that those monsters' caves were dug up by themselves. Maybe Xia Yu doesn't need to find any robots, and directly arrests the strong man of Fourteen Niang and asks her to help her repair the base, but this seems to be a violation of the juvenile protection law and the illegal use and exploitation of child labor.

Of course, this is just a joke, Fourteen Niang can only dig, but building a base is not so simple as digging. The process of digging is only equivalent to demolishing the existing ones, and building a base with a high degree of technology requires many complicated steps, which are essential.

However, it is already remarkable to be able to drive the hole to a depth of five kilometers without the action of wooden stakes and other supports, and Xia Yu slid all the way to the bottom of the cave wearing oxygen.

And then he was shocked, this, how is this possible?

It's not that Xia Yu has entered the world of Journey to the Center of the Earth, nor is it the complete world of the underground hollow theory of the black brother in King Kong Skull Island.

It's that there's a weird crack here.
