Hundreds of black birds were surging in flocks, and their target was the cave where Dadao and the others were.

The expressions on the faces of Big Sword and Bottle Cap changed instantly. These big birds were just ordinary monsters. If they were more than a dozen, they wouldn't care at all, but the hundreds and thousands of them came overwhelmed, like a large cloud that covered the sun, which was a bit too terrifying.

"Don't be afraid, we are in the cave, as long as we keep the entrance of the cave, the birds can't do anything to us." Ye Mei said hurriedly.

When Boiler heard this, he calmed down his panic expression and quickly said, "Yes! I think so too, it's just some birds, just a little bigger than other birds, it's nothing great."

"This bird should look delicious." Dadao cooperated.

These words made Bottle Gaier and Ye Mei look at Dadao speechless.

As the three girls were talking, a black bird suddenly entered the cave. The big knife raised his hand and directly split the black bird in half. The smell of blood instantly filled the entire cave.

Immediately afterwards, two black birds came in and were killed one by one by one by one by a big knife.

In this way, the three women's previous worries disappeared, and this cave was a fortress that was easy to defend and difficult to attack.

No matter how many big birds there are outside, they can't do anything to them.

The bottle cap was nervously clenched his fists at first, but now he has completely relaxed. Just leave this kind of strength to Dadao.

Ye Mei's solemn gaze also became relaxed.

The big bird outside began to hover around the entrance of the cave, and obviously he didn't dare to rush into the cave easily anymore.

These big birds hovered for more than ten minutes, and then gradually dissipated.

Just when the three girls thought the other party was about to give up, the big birds that had left suddenly flew back from a distance. They rushed into the cave from a high place in the air, but suddenly turned a sharp turn of V, and then a black thing was thrown down for them like a bomb.

With a bang, the black thing hit the stone wall heavily, and then it was like a heavy rain. Hundreds of black birds dropped bombs in one after another, hitting the stone wall with crackling heavy blows.

The three girls hiding in the cave have never seen this scene. Although those dark things can rarely be thrown into the cave, the trembling feeling that was like hiding in a small wooden house in a storm still made the three girls feel very uneasy.

"What are these stupid birds doing? Could they be shitting, are they?"

The bottle cap twitched his nose hard, and a foul stinking swelled in his face, and his voice trembled.

Ye Mei looked at the black dirty rolling in and looked ugly: "Oh, this thing has corrosive power."

I saw the ground where the black dirt was in contact with was corroding and shattering little by little, and the whole ball of dirt was slowly sinking.

"They, they want to corrode the mountains? Are they crazy?"

The bottle cap exclaimed nervously.

Ye Mei said with an ugly face: "I'm afraid that's what they think."

The bottle cap kept backwards: "I don't want it, I don't want to touch those dirty and smelly things."

The bang bang bang bang bang bang bang bang bang bang bang kept ringing, and with the sound of rocks breaking and peeling off, it sounded so thrilling at this moment.

The strong mountains seemed to turn into something as fragile as cookies in front of these birds' excrement.

The entrance of the cave was completely blocked by black dirt at this time, and there was no way out.

Even if there is a way out, they dare not jump out of the hole. Not to mention whether they will get dirty, hundreds of big birds alone can tear them to pieces.

A strong odor came to your nose. The thing not only had corrosive power, but also had strong toxicity. It made people feel drowsy when they smelled.

"Oh no! We can't hold on here for long!"

Ye Mei reached out to cover her mouth and nose, and was about to rush out to death, a gas mask was handed over.

Ye Mei looked at the bottle cap in surprise, and saw that the bottle cap took out two gas masks from behind like a magic trick, and brought one of the big knife with him.

"We can only dig a road and get out!" The bottle cap looked towards the end of the cave.

"We will sooner or later be drowned by bird poop here. The best way is to continue digging the cave. On the one hand, we can use the excavated stones to block the entrance of the cave, and on the other hand, we can expand the space for activity. If the cave can be opened, we can escape from the back of the mountain." Ye Mei said in a deep thought.

I saw the bottle cap take out two alloy shovels from behind and hand them to Ye Mei and hand them to Dadao.

She pinched her waist and said, "Dig quickly, don't stop, otherwise we will be done!"

Ye Mei looked behind the bottle cap and said curiously: "Where did you take it out? What kind of magical power are you?"

The bottle cap blinked with big eyes and said proudly: "This is something my grandma made, called the shrinking bag. There are four cubic spaces inside, and all the treasures are placed inside."

Ye Mei himself is a disciple of Jiuxing Hanmei, but he is far from touching the deep secrets of the Academy of Sciences. If the bottle cap says it is true, then this shrinking capsule is simply the most treasure in the world.

Moreover, the four square meters are already very large and can accommodate a lot of things.

"Have technology now reached such a high level?" Ye Mei asked in disbelief.

The big knife said on the side: "In fact, it was not developed. It is said that a crystal was found in a broken void crack. That thing cannot be refined by humans."

Ye Mei was quite disappointed when she heard this. If the shrinking capsule could be produced in large quantities, it would not take long before the war between humans and demons would come to an end, and humans would definitely become winners.

Ye Mei took the shovel to the end of the cave and shoveled hard to the rock.

To Ye Mei's surprise, this alloy shovel is very sharp and easy to use, far from comparable to an ordinary shovel. Digging up a stone saves time and effort like cutting tofu.

When Ye Mei watched, she realized that this shovel was actually a fetal device, and it could become an orifice device after refining it.

For a star cultivator like Ye Mei, it is definitely a dream to have an orifice tool. Unexpectedly, the bottle cap can be taken out casually. No, it is exactly the same as the two!

Obviously this is specially prepared for their entry into the demon world this time.

It is estimated that there are only these two pieces, so the bottle cap only took out two alloy shovels.

Even if three people take turns digging, it is not easy to dig through the mountains?

However, the more they dig forward, the violent mountain behind them shaking, and the loud noise that hit the mountain became more and more blurred.

At least even if they cannot dig out from the other side of the mountain, they will not be threatened by the big birds here.

The three of them breathed a sigh of relief, and the speed of digging gradually slowed down.
