"Boy, you're not its match yet, run," the bastard reminded with some anxiety. 『』

But Murong Bai was already enthusiastic at this time, and he didn't think about running away at all, but the black big knife in his hand couldn't exert its power in the water at all, and in desperation, Murong Bai's divine sense swept away, and he immediately sacrificed a red umbrella and blocked it above his head.

When Murong Bai had just opened the red umbrella and raised it above his head, the huge white tail covered with fish bones also burst out.

bang

Although it was in the water, this huge muffled sound still shook Murong Bai's eardrums, but the moment the huge white tail hit the red umbrella, it was like encountering a nemesis, and the painful dragon crocodile let out a strange scream.

"Hey, there is a door" Murong Bai's eyes lit up, and he didn't care about the buzzing in his ears, so he was about to hold a red umbrella and kill the dragon crocodile.

"Boy, it's important to get down to business, this little earthworm, I'll clean it up when I come back" The bastard hurriedly reminded when he saw that Murong Bai was about to rush up.

"Okay, when Lao Tzu comes back, he must slaughter it, and let's eat grilled fish together when we go back, haha" Murong Bai saw that he could kill the dragon crocodile, and immediately lost most of his heart, and he no longer cared about the courage of the moment, after all, the purpose of diving underground this time was not this, and it was impossible to delay too long for a strange fish.

With the protection of the red umbrella, Murong Bai no longer had to be afraid of the sudden attack of the dragon crocodile, so he continued to use the jack pendant unhurriedly, in a free-fall way, while diving, while running the Qiankun Dou to restore the cultivation in the body.

Half an hour later, Murong Bai's feet touched the ground.

"Boy, through this layer of dirt, there's a layer of stone underneath, you'll have to dig with a knife," the bastard reminded in time.

"I'm going to go, how long will this be dug up to what year and month" Murong Bai suddenly looked depressed, Nai is a bear, Lao Tzu has become a whack-a-mole now, and I don't know how this Xiaoyao Mountain Villa brought this earth fire to the Danfang, and I am afraid that such a huge project will not be able to be connected in a year or two.

In fact, Murong Bai is salty and eats radishes and worries lightly, Xiaoyao Villa naturally has a set of formations to connect the earth fire, otherwise this underground is both stone and water, even if the earth fire can be connected, it is also mediocre, and it cannot meet the requirements of alchemy.

"Don't think too much about it, you just need to dig a passage, and this layer of stone is not too thick, if you are lucky, you may be able to dig up one or two black stones" The bastard's eyes flashed, and he laughed.

"Black Yaoshi?" Murong Bai's eyes lit up.

"Obsidian is very rare and is usually found deep underground, depending on your luck. Seeing that the success had aroused Murong Bai's interest, the bastard hurriedly plugged the loophole in what he had just said, in case there was no Hei Yaoshi, this stinky boy would find trouble with the old man again, wouldn't it be impossible to steal chickens and rice.

"Okay, as long as there are good things to stimulate, Lao Tzu is willing to dig for a year" Murong Bai rolled up his sleeves, raised the black big knife in his hand, and dug it up.

But just after digging a few times, Murong Bai suddenly stopped and asked a key question, "I wiped it, I almost forgot, you said that this stone layer, since it is so thick, how should the excavated stone be placed?"

"It's very simple, you've heard that in this world, there is a class of warriors who specialize in stealing and digging up the graves of ancient warriors, and the methods they use come in handy at this time..."The bastard patiently explained.

As soon as the worries were gone, Murong Bai threw off his arms, picked up the black big knife and began to dig up, digging stones with magic weapons, naturally like cutting tofu, and after a while, Murong Bai dug more than a zhang deep.

"Hei Yaoshi, hurry up and jump out, I like you so much" Every time he dug a few knives, Murong Bai said a word.

I have to say that once a person has a direction and goal to move forward, he will not only devote himself to it, but also work very hard.

And success often favors these people who persevere in the pursuit of goals every day, even if it is not successful temporarily, it will only lay the foundation for greater success in the future.

Time passed little by little, Murong Bai had dug for nearly a hundred zhang or so, his hands were not tired, but his mouth was a little dry, for no other reason, since he started digging stones, his mouth has not stopped, so he can't say that he hasn't played, if he is replaced by anyone, his mouth will not be able to stand it.

Although his mouth was sour and his skin was dry, Murong Bai still did not lose confidence, sat in the stone cave, took out a jar of green wine and a package of braised beef from the Sumeru ring, and ate and drank in a big gulp.

"Bastard, how long will it take to dig it up" Murong Bai said casually while eating and drinking.

"This... That one... I guess in half an hour it will be about the same. Although the bastard's divine sense is strong, it is not strong enough to penetrate the stone layer, but in the face of Murong Bai's inquiry, he can't help but keep silent, so he said vaguely.

"Cut, don't be so afraid of me, I won't eat you, why are you stammering. Although Murong Bai was very arrogant, it didn't mean that he had less eyes, so he naturally knew the little thoughts in the bastard's heart.

"No, did the old man stutter just now?" the bastard didn't admit it.

Murong Bai pursed his lips and didn't speak, and after a while, after eating and drinking, Murong Bai roared, picked up the black big knife, and began to dig again.

This time, Murong Bai dug for a long time, and in the end, he could even feel the slightest heat coming from the stone walls around his body.

"It seems that it is not far from the earth fire" Murong Bai spat at the mouth and continued to dig, but he had only dug for less than a few breaths, and suddenly the tip of the black big knife seemed to have touched a hard object.

"Hey, what's going on?" Murong Bai hurriedly took out the red umbrella and lit it, dug to the side a few more times, and then reached out, and at the tentacle, he felt that the stone below was a little warm and smooth, and Murong Bai's arm slammed into force, and he took out a fist-sized black glowing stone at once.

When I put it in front of me, it turned out to be a purple-black stone that emitted a misty purple light and had many facets.

"Could it be that this is Hei Yaoshi," Murong Bai said in a low voice.

"You kid is really blessed, you really let you touch it. The bastard was very surprised, originally he wanted to use the Black Yao Stone to stimulate Murong Bai to dig up the stone layer, but he didn't expect that Murong Bai really dug it.

"What is this black stone for? Murong Bai asked puzzled while looking at the purple-black stone over and over.

The so-called Black Yao Stone is an extremely rare natural stone that contains space, which is the best material for refining magic weapons, and it itself has a sound transmission effect.

If a piece of black yao stone is cut into several pieces, then between these black yao stones, it has the effect of sound transmission, which is very similar to the sound transmission note, except that the sound transmission note is one-time, and the black yao stone can be reused infinitely, of course, this is only one of its functions, and the most important function is the main material for refining a magic weapon such as a flying boat or space
