"The zero-point reversal has not been able to make them all die, if the aborigines of this world are completely wiped out because of the upgrade of this small world, then the creation god of creation is too much of a failure. Pen %Fun %Pavilion www.biquge.info"

"Therefore, this place has become like this, perhaps the reason is that this craftsman's soul smelting furnace is also regarded as a kind of architecture, so it has not disappeared in the changes of the world, but has been preserved, and even such a large area of hollow land has been vacated around it for no reason."

After pondering for a while, Su Qing could only accept Xia Aya's analysis and guess, because now only this explanation makes the most sense.

Well, it still doesn't matter what the truth is, they don't bother to know the so-called truth, as long as they believe their own guesses.

So then, the two of them finally thought of the problem of returning to the ground, and now they are trapped here, and the spiral staircase and the mine road have all been sealed, and they have to dig a new road to get back to the surface and back to the comfort of their homes......

Well, it's another chore......

But......

Xia Aya suddenly looked up and saw the pitch-black hollow above her head, her eyes lit up, she seemed to ...... I came up with a way to get back to the ground without having to dig and mine......

Didn't you say that before? It would be a marvellous sight to see if the walls around them, including the pitch black above them, could be lit up with the glow of torches.

And now, Xia Aya suddenly thought that since all the top of this is hollowed out, then perhaps, the pitch black above this head will lead directly to the ground?

Even if it doesn't actually lead to the ground, if you can climb to the top of this pyramid, the height of that place is definitely not far from the ground.

After all, their craftsman's soul smelting furnace is only built at a depth of 100 meters underground, although the higher the smelting furnace, the more capacity it has, and the more metals it can smelt at the same time, but the smelting furnace is not as high as possible, the smelting furnace with a height of 100 meters is completely enough, or even more than enough, and no matter how high it is, it seems a bit cumbersome.

So, they are only a hundred meters away from the ground now, and if they need to dig a spiral staircase to the ground again, it must be a difficult chore, because even if they have upgraded to an aluminium pickaxe, it will not be as easy to mine a stone block as in the game, a second is a piece, and after upgrading the redstone many times, it may even be automatically destroyed with a simple wave of the block in front of them.

It also takes about ten times for the acid-resistant aluminum pickaxe to dig the stone, which seems to be a lot less than the bone pickaxe flint pickaxe they used at the beginning, but don't forget that the acid-resistant aluminum is a high-grade alloy, and its quality is not comparable to that of bone and flint, and the same volume of acid-resistant aluminum pickaxe is much heavier than the flint pickaxe.

They also need to use more physical strength to use acid-resistant aluminum equipment, and although the efficiency of acid-resistant aluminum digging stones has become faster and the number of digging times has decreased, the physical consumption is not much less than that of flint pickaxes.

After all, they don't have the unicorn arms like Steve in the game, they can't easily pick up anything, and using an aluminum-resistant pickaxe makes them so tired, they wonder if she can really take it in her hand and eat it if she makes a golden apple in the future?

Don't say you can't take it, golden apples or something, this heavy metal is definitely beyond the standard, if you really eat it, in reality, it's going to die! Really big husband?

Maybe the rules of this block continent are different from those of Earth...... After all, this is modeled after MC...... Oh no, it's MC a game based on this world.

In fact, if they had upgraded their talents in the mining column at the beginning, they would definitely not be as tired as they are now, as long as they can improve their mastery of the Pickaxe to level 5, then using the Acid-Resistant Aluminum Pickaxe will only make it easier to send it to the bone, even easier than the Bone Pickaxe, and the mining speed and efficiency will also increase.

As for using a bone pickaxe, it's even more light, but that doesn't make much sense, and the efficiency is far worse than that of an acid-resistant aluminum pickaxe.

It's just that at the beginning, they only thought about using their talents to improve their strength, and neither of them noticed these "life skills", but now although they can also use the remaining experience to upgrade directly, no one thinks about it......

Maybe when they were looking at the talent tree, they just ignored the mining talent, and they were really interstellar players......

Therefore, if they want to dig a spiral staircase or a diagonal tunnel back to the ground, they are reluctant to do so - one of the reasons is naturally because it is too troublesome and too physically demanding, and it is estimated that they will be exhausted when they return to the ground, and what if they happen to encounter an evolved monster and wipe them out?

They cherish their lives very much!!

The second is also because the spiral staircase set up before was reset and filled under the world upgrade, and they think that if they dig up another spiral staircase, the same thing will definitely happen again when the world is upgraded, so will they have to dig it again next time they come back here?

So do they have to reopen the mines every time the world is upgraded?

That's too sad, isn't it? You must know that their mine is not just a spiral staircase from 100 meters underground to the ground, although it will be very laborious to dig this alone, it can be completed in a day, at most it will only take a little more effort, but...... Their entire mine is an ultra-deep mine that is 1,000 meters underground!

A hundred meters of spiral staircase is enough, and they can dig it up if they want to, but ...... This kilometer of mine tunnels is by no means a re-dug road.

Every time the world was upgraded, they had to dig a thousand meters from the ground again, and they didn't want to do that anyway.

Because it was too difficult to dig a 1,000-meter mine road, you must know that it took Xia Aya a month to dig from the ground to a depth of 600 meters, although it was also because there was no fresh air from the rose bush at that time, and they had to rest to a certain extent, but the difficulty of digging to the depths was also visible.

Even if there was a rose bush later, it took Xia Aya a lot of effort and time to dig from 600 meters to 1,000 meters, and if she had to do it all over again, even if she was accompanied by Su Qing, Xia Aya would definitely not want to experience that feeling again.
