These caves are obviously natural, but the rock walls are very smooth.

It was as if magma flowed through here and then disappeared.

Zhou Yu originally thought that the cave would be very humid, but as the two continued to walk inside, they found that it was obviously very dry.

I think it is for this reason that the swiftlets choose to settle here.

After they walked a little further, Zhou Yu started to worry about the little princesses.

Seeing that it was safer here than outside, he flashed and brought everyone in.

Suddenly arriving in the cave, the little princesses became excited.

With the help of the searchlight, the little kid ran inside without waiting for Zhou Yu to speak.

Seeing this, Zhou Yu quickly spoke out to stop it.

Li Junxian and he protected them in the middle, one in front and one behind, and then they walked into the cave again.

After walking a short distance and turning a corner, Zhou Yu saw a faint light ahead.

After walking a few steps in the direction of the light, the view ahead suddenly became clear.

It was not until then that Zhou Yu discovered that the caves he had just seen actually all led to here.

The space in front of me looks like an upside-down iron pot.

There are a few "holes" scattered on the bottom of the "iron pot".

The light you just saw came from these "holes".

The area here is very large.

As far as the eye can see, it is at least several hundred square meters.

The highest point of the pot bottom is at least ten meters high.

Following the light of the searchlight, Zhou Yu also saw clearly the situation at the "bottom of the pot".

From the edge to the top, it is densely packed with small transparent corners.

From a distance, it looks like a protruding fixed buckle on a climbing wall.

That is to say, the arrangement is not very regular, otherwise at first glance, you would think they are pieces of fish scales!

"Wow, little bird, there are so many little birds here~"

The light from the searchlight startled many swiftlets in their nests.

The little girl had seen many birds, but this was the first time she had seen so many as today.

Perhaps because these swiftlets had rarely seen humans, after being startled, they did not fly directly out of the cave, but instead hovered around their own nests.

After a while, making sure there was no danger, they flew back into the nest.

Compared to the surprised little kid, Li Lizhi next to her was more curious.

She had eaten bird's nest often before.

It’s just that they are all served in front of us after they are made.

Seeing the nearby bird's nest filled with feathers and other debris, she couldn't help but ask out of curiosity.

"Young Master, why are these bird's nests different from what we usually eat?"

"The bird's nests you usually eat are carefully selected. Normal bird's nests look like this."

As Zhou Yu spoke, he swept the area with the searchlight again.

As the swallows in the nest took off and hovered again, Zhou Yu roughly figured out the number of swallows.

After observation, he found that at least 60% of the bird's nests here did not have swallows.

Even if we ignore the swallows that go out to look for food, it is estimated that 30% of the bird's nests are idle.

There is no need to have any psychological burden when collecting in this way.

Just as he was looking around, the little kid next to him had run to an empty bird's nest without him noticing.

Everyone thought she was just curious.

Who knew that the next moment, the little girl opened her little mouth and bit it.

Seeing this, Zhou Yu hurried forward and said, "Mingda, you can't eat this directly."

Unfortunately, a large piece of the bird's nest with bird feathers had been bitten off by her little silver teeth.

Awooo~Awooo~

As the little girl chewed with big mouthfuls, her originally smug face instantly turned bitter, "Puff~Puff~Puff~Little Nianjun, this bird's nest is not good~"

Zhou Yu: ...

It seems that this greedy little girl didn't listen to what I said at all.

Seeing the little girl sticking out her tongue, Zhou Yu had no choice but to reach out and pick out the remaining bird's nest from her mouth.

After doing all this, he handed the water bottle to the little girl and said, "Hurry, drink some water and rinse your mouth."

Hearing Zhou Yu say this, the little girl hurriedly picked up the water bottle. After two gulps, the little girl froze on the spot.

Facing everyone's puzzled gazes, the little girl said sheepishly, "I...I accidentally swallowed it..."

Seeing the little girl wiping her mouth, Zhou Yu, who was about to say something, suddenly slapped his forehead helplessly.

He found a pagoda candy and put it into the little girl's mouth, then Zhou Yu started digging with an engineering shovel.

I thought it was just a bird's nest and I could make it easily by doing it myself.

Who knew that after all the operations, the entire bird's nest ended up stuck to the engineer shovel.

The attempt was not going well, so he stopped digging immediately.

It is true that these bird's nests are good things, but if they are all stuck together, no matter how good the quality is, they cannot be called treasures at all.

He frowned and thought for a long time, but could not find any memory related to digging bird's nests.

After hesitating for a moment, Zhou Yu decided to try again.

This time, he did not act rashly, but took a cup of water and sprinkled water on the engineer's shovel first.

Because there was water on the engineer shovel, the second bird's nest did not stick together.

As a complete bird's nest was dug out, Zhou Yu's face showed joy.

Just as he was about to continue, Li Junxian came forward and said, "Young Master, digging like this is too slow. Instead of doing it yourself, why not bring all the soldiers from the Flying Cavalry Battalion here?"

"That makes sense."

Zhou Yu was stunned when he heard this, and then he patted his forehead again.

I originally brought the little princesses with me because I wanted to let them experience the fun of robbing bird nests.

But judging from the current situation, their focus is obviously on eating.

Thinking of this, he was too lazy to waste any more time.

He put the engineer shovel behind him, and then disappeared with the little princesses.

As for Li Junxian, who made the suggestion, he was left here.

It was not until half a while later that Li Junxian, with an incredulous look on his face, could not help but shout "Fuck!"

Unfortunately, apart from the echo in the cave and the startled swiftlets, no one responded to him.

Considering the cable when coming down, he immediately prepared to go outside.

But he had just taken two steps when he heard bursts of exclamations from behind him.

Li Junxian turned around and saw Zhou Yu and a group of soldiers from the Flying Cavalry Battalion appear here.

In their hearts, Zhou Yuben is like a god.

Even though they suddenly came here from the yacht, the soldiers of the Flying Cavalry Battalion were only curious and excited, without any other emotions.

However, the densely packed bird's nests quickly attracted their attention.

So, without waiting for Zhou Yu's arrangements, they couldn't wait to start digging.
