Stepping on the demon door, the witch becomes the strongest.

Chapter 411 You are a duck
The crack is very narrow, allowing only one person to pass through. There are uneven rock walls on both sides, which look no different from ordinary cliffs and there is nothing unusual.

But since there is a no-fly zone here, it means that the two of them must be in the secret realm at this time - considering that they have not passed through anything similar to the entrance to the secret realm before, they can only guess that there may be something strange about the waterfall.

Yan Yu held his chin and thought silently, when suddenly someone patted him from behind.

"It's so cold." Tang Xiaolian complained, "Captain Yan, where should we go next?"

"It doesn't matter which way we go," Yan Yu replied. "We should be inside the formation now, so our sense of space and direction is completely messed up."

"I don't quite understand." Tang Xiaolian asked, puzzled, "What would happen if we turned around and went back the same way?"

Although Yan Yu did not understand the art of formations, he had experienced countless secret realms in his previous life, and he had accumulated a lot of experience in dealing with this kind of formation. He just answered calmly:
"If you turn around and go back, and I stand here, there are three possibilities."

"First, you kept walking back without turning around, and ended up coming back right in front of me. This is called an upside-down formation. Front is back, and back is front. No matter how far you go, you're just going in circles."

"Second, no matter how long it takes you to walk back, if you turn around and walk towards me, you can probably get back in just ten minutes. This is called the Expandable Ruyi Formation. It can be longer or shorter as you wish. Space will automatically stretch in the direction of your movement, so no matter how far you walk, you will just stay where you are."

"Third, you keep going back further and further, even if you walk a thousand kilometers, ten thousand kilometers, and still can't find the exit. This is called the Mustard Seed Sumeru Formation. It looks extremely small, but it's actually enormous. The volume of the entire formation can even reach astronomical units. Continuous movement is absolutely impossible to reach its boundaries."

"Captain Yan, how do you know so much?" Tang Xiaolian was stunned.

"Nonsense, I'm the captain." Yan Yu said as a matter of course, "Shouldn't I know more than you?"

"Our Captain Zhou is also the captain." Tang Xiaolian subconsciously retorted, "But she knows nothing except combat-related matters."

Haha, that’s true, but you can’t let Zhou Hongyu hear this.

"Anyway, this is not the point." Yan Yu said, "The point is that we must find a way to break the formation, otherwise we will be trapped here."

"Can't we notify the Pingxi Army outside to come rescue us?" Hearing him say this, Tang Xiaolian suddenly felt a little scared, "I don't want to stay in a place like this!"

"How do you notify me?" Yan Yu asked her, "You don't have a live camera with you."

"But Captain Yan will definitely have a solution, right?" Tang Xiaolian asked hopefully, "You're the captain."

"Hmm." Yan Yu just hummed and ignored her, holding his chin and continuing to think.

Tang Xiaolian became more and more uneasy, thinking that if Captain Zhou was here, although he would not have any good solutions, he would at least say something to boost morale. Captain Yan's silence was too scary!
If Captain Yan and I were trapped here forever, for example, for three to five years... I wouldn't die, after all, I'm fasting and don't need to eat or drink, but I would definitely be bored to death.

If Captain Yan becomes beastly and wants to do shameless things with me for fun, how can I refuse?

It seems that I can’t refuse, after all, I can’t beat him!

Why don't we put a curse on him now?

How is that possible?! If I knock Captain Yan unconscious, I won't be able to leave here alone!
"Ahh." Seeing Yan Yu remained silent, Tang Xiaolian cried out a few times, "Ahhhhhh."

"Don't make any noise, I'm thinking."

"Has Captain Yan come up with any solution?" Tang Xiaolian asked.

"I definitely can't think of anything if you make such a fuss." Yan Yu replied.

"If Captain Yan hadn't rushed here rashly, I wouldn't have been forced to follow him in. Now we are both trapped in the secret realm!" Tang Xiaolian went crazy.

"Why don't you say that if you hadn't followed me, this wouldn't have happened?" Yan Yu squinted.

"Okay, okay, it's all my fault." Tang Xiaolian gave up on herself and didn't care about getting her clothes dirty. She just sat down on the moss-covered rock and began to cover her face with her hands to wipe away her tears.

Yan Yu looked at her calmly. Although the little girl cried for a long time, there was not a single tear on her face. She was still peeking at him through her fingers.

He cast his gaze towards the crack in front again. Since it was the old man with long eyebrows who asked him to come here, it meant that the secret realm here must be related to the sword, and it was most likely a test-type secret realm, and there would not be any unsolvable problems.

Test...test?

A test for the Sword Immortal, right?

Yan Yu secretly made sword gestures, and the Huangting Sword suddenly flew out from behind him, slashing at the surrounding cliffs.

Tang Xiaolian was startled, thinking Captain Yan was about to yell, "Noisy woman! I'll kill you!" She instinctively covered her head with her hands to defend herself, whimpering, but all she heard was another earth-shattering crash. She quickly opened her eyes and saw Yan Yu, slashing the side of the rock face with his sword technique, shattering it, revealing a deep cave entrance.

"That's right." Yan Yu observed the cave entrance for a moment, then nodded with satisfaction. "I was wondering why the rock wall here was different from others, so smooth. It turns out there's a stone door—it was just covered in moss before, so it couldn't be seen."

He walked forward calmly, and Tang Xiaolian quickly stood up and followed him.

The cave was very deep and there was no light at all, so Yan Yu turned on the flashlight mode on his phone and walked in front to lead the way.

Tang Xiaolian followed behind, a little frightened by the gloomy atmosphere around her. She couldn't help but try to grab Yan Yu's arm, but halfway through she felt something was amiss and instead grabbed his sleeve.

"What's wrong?" Yan Yu asked without turning his head.

"Be careful, there might be an ambush ahead." Tang Xiaolian was too embarrassed to admit that she was afraid, so she said seriously, "Let's stay closer so we can look after each other."

"Yeah." Yan Yu thought to himself, that's right, I'm not afraid of any ambushes or sneak attacks, but this little girl is an insect-master monk. It is well known that a weak profession like the insect-master monk relies heavily on the cover of companions, so it is natural that she sticks to me subconsciously.

He continued to stride forward. Tang Xiaolian couldn't keep up with his speed and shouted anxiously:

"Slow down, Captain Yan, please slow down!"

"Or you can walk faster." Yan Yu said.

"I can't walk in long strides in a skirt!"

"Then take off your dress."

Tang Xiaolian had no choice but to take advantage of the darkness and start to take off her clothes.

"Don't use your spiritual sense to secretly scan me." She suddenly reminded.

"What's there to sweep?" Yan Yu frowned and asked, "Can't you just wear your clothes inside and take off the outside? It won't expose your body!"

"I'm afraid the sound of me taking off my clothes will cause you to have bad thoughts." Tang Xiaolian explained.

"Are you usually so busy in the team?" Yan Yu asked curiously.

"No way!" Tang Xiaolian defended herself, "In the team, everyone will take care of me!"

"Then you have to be careful, I'm not the kind of captain who will take care of my teammates." Yan Yu said with a sneer.

"What type of captain is Captain Yan?" Tang Xiaolian asked casually as she took off her dress.

"My leadership style is primarily strict," Yan Yu replied. "If anything goes wrong during training, I'll either beat you or scold you. No mercy! You must obey my orders no matter what happens. Don't think you can be forgiven by crying about it later. That won't work with me. Do you understand?"

"I understand." Tang Xiaolian tied the dress around her waist, tied a knot that would not affect her movement, and muttered to herself.

Beating or scolding? I don't believe it. Your team is full of girls, how could you possibly beat or scold them so harshly?

Well, coming to that, since Team Yan is here to explore the secret realm this time, why doesn’t he bring his teammates along?
"Captain Yan, Captain Yan." After following Yan Yu for a while, Tang Xiaolian couldn't help but ask curiously, "Why did you come here alone this time?"

"Because it's quieter when you do things alone." Yan Yu replied.

"No, I think it's safer to have more people, so we can deal with all kinds of emergencies." Tang Xiaolian expressed his objection.

"When there are too many girls, they will chatter and it gives me a headache," said Yan Yu.

"So in Captain Yan's eyes, am I also the chattering type?" Tang Xiaolian asked.

"You're the quack-quack type."

"What? Captain Yan, do you think I'm a duck?" Tang Xiaolian expressed dissatisfaction.

"I mean, you can't help at all when you encounter a situation. You can only make noises and wait for me to kill you." Yan Yu laughed at her.

Tang Xiaolian puffed up her cheeks in anger, but when she thought about her performance while trapped in the chasm just now, it was indeed not convincing.

Humph, I have to perform well later and make Captain Yan take back those words that looked down on me!
