The fairy love story between Bi Yao and Li Yuan after traveling through time

A cold wind howled out from the depths of the castle, blowing up the fallen leaves on the ground and making sounds like the howling of ghosts and wolves.

Bi Yao and Li Yuan stood side by side in front of the tightly closed castle gate. The air around them seemed to be frozen, so oppressive that it made them breathless.

"Wow, this door lock is more complicated than my WiFi password!" Bi Yao looked at the dense runes on the door and couldn't help complaining.

Li Yuan carefully observed the rune, gesturing with his fingers in the air, muttering to himself, "The Eight Diagrams of Heaven and Earth, the intergeneration and mutual restraint of the Five Elements... This rune has something special!"

"Nonsense! How can it be called a forbidden technique if it doesn't contain something?" Bi Yao rolled her eyes at him. "Hurry up, stop doing academic research here and open the door!"

"Yaoyao, don't be anxious. This thing might backfire!" Li Yuan said as he carefully injected spiritual power into the rune.

The rune instantly lit up with dazzling light, and a powerful recoil force pushed Li Yuan back several steps. He staggered and almost fell.

"Oh my god! This thing is really electrified!" Bi Yao quickly supported him, "Are you okay?"

Li Yuan rubbed his chest, his face pale: "It's okay, just a little numb."

"Nude? I think you've been electrocuted!" Bi Yao teased, "Let me try!"

Bi Yao took a deep breath and injected his spiritual power into the rune.

The rune lit up again, but this time the recoil force was even stronger. Bi Yao was directly blown away and fell heavily to the ground.

“Cough cough cough…” Bi Yao coughed a few times, feeling as if all her internal organs were displaced. “This thing… is even worse than my ex!”

Li Yuan quickly ran over and helped her up: "Yaoyao, are you okay? I told you this thing is dangerous!"

"It's okay, I won't die." Bi Yao wiped the blood from the corner of his mouth, a hint of stubbornness flashing in his eyes, "I just don't believe that I can't cure it!"

The two tried again and again to decipher the rune, but each time they failed.

Their strength was gradually consumed and their bodies became weaker and weaker.

"Yuan..." Bi Yao leaned on Li Yuan and said breathlessly, "How about...we change the entrance?"

Li Yuan looked at her exhausted appearance and felt distressed: "Yaoyao, you are already like this, and you still want to be strong?"

"I...I won't give up..." Bi Yao bit her lip, "I've come this far, how can I give up!"

Li Yuan sighed and was about to speak when he suddenly felt a strange aura coming from deep within the castle...

He suddenly raised his head and looked in a certain direction of the castle, with a trace of fear in his eyes: "Yaoyao, be careful!"

At the same time, Bi Yao also felt a strong sense of crisis, and she subconsciously tightened her grip on the sword...

"What is that..." Bi Yao's voice trembled.

In the darkness, a pair of scarlet eyes slowly opened...

A cold wind carrying dust swirled in front of the castle.

Bi Yao leaned against the wall, wiped the blood from the corner of her mouth, and spat, "This broken door, is it inlaid with diamonds or something? It's so hard!" Li Yuan was also exhausted. He said with a gasp, "Yaoyao, how about we... a strategic retreat? Try through the window?"

Bi Yao glared. "Retreat? I don't even have that word in my vocabulary! There must be something good hidden behind this door. Think about it, in TV dramas, isn't the key prop for the protagonist to level up behind the most difficult door?"

Li Yuan thought about it and it seemed to make sense. He scratched his head and said, "Then... try again?"

Bi Yao nodded, took a deep breath, and was about to mobilize his spiritual power again when suddenly, dazzling red rays of light shot out from the eyes of the statues around the castle, as fast as lightning, and rushed straight towards them!

"Oh my god! What the hell!" Li Yuan pulled Bi Yao over and barely avoided the attack.

The red light hit the ground, instantly creating a big hole and sending debris flying everywhere.

Li Yuan swung his sword to block, but found that a piece of the sword was melted by the red light!

"This thing... is quite powerful!"

Bi Yao narrowed his eyes and observed the statues and the trajectory of the red light.

"Wait, this red light... doesn't seem to be shooting randomly!" Her mind was working rapidly, and modern geometric knowledge and formation knowledge were wonderfully combined.

"Yuan, look at the positions of these statues and the order of the red light attacks. Do they resemble each other?"

Before she could finish, a new round of red light attacks came.

The ground was so full of holes that it looked like the surface of the moon.

Bi Yao pulled Li Yuan and dodged in the dense attacks, facing danger all around.

"Like what?" Li Yuan asked loudly while dodging.

Bi Yao's lips curled up into a confident smile: "Like... a math problem done by an elementary school student!"

Suddenly, she stopped abruptly and pointed to an open space to the left of the castle gate: "Go there!"

Although Li Yuan didn't understand, he followed her without hesitation.

The moment they stopped, all the red light gathered around the open space, forming a strange encirclement.

"Now..." Bi Yao looked at the flashing red light, a gleam in his eyes, "It's time to show your real skills!"

Bi Yao pointed at the open space and said firmly: "Look, the trajectories of these red light attacks are actually regular, just like a word problem. As long as you find the formula, you can solve it!" Although Li Yuan was confused, he still chose to believe his wife unconditionally.

After all, past experience told him that Bi Yao's "elementary school math problems" could often solve difficult problems that even gods would have a headache about.

Bi Yao observed the angle and time interval of the red light while calculating rapidly in his mind.

She kept muttering to herself, "One, two, three, four, five, go up the mountain to fight the tiger... No, it's trigonometric functions, geometric figures, and... um... the Pythagorean theorem!" Li Yuan almost laughed out loud when he heard her strange mnemonics, but he didn't dare to disturb her thinking.

"Got it!" Bi Yao's eyes lit up, and she pulled Li Yuan up and started to shuttle in the red light.

Her steps seemed casual, but they contained hidden secrets. Every step she took was just right to avoid the deadly red light, and she could even use the rebound of the red light to guide them to attack the runes on the castle gate.

"Wow, Yaoyao, your movement is even better than the king in the canyon!" Li Yuan couldn't help but admire him, waving the sword in his hand to shatter some red lights that had escaped the net.

The two of them coordinated perfectly, dancing gracefully in the deadly red light like dancing.

As the red light continued to bombard the gate, the runes on the gate gradually dimmed and lost their original brilliance.

With a "click", the heavy castle gate slowly opened, and an ancient and mysterious atmosphere blew in.

Just as the door opened, a golden light shot out from the crack in the door, illuminating the faces of Bi Yao and Li Yuan.

The two were surprised to find that a golden key appeared where the rune was originally!

"Oh my god, this operation is really profitable!" Li Yuan grabbed the key and examined it carefully. "This thing... looks very powerful!"

Bi Yao looked at Li Yuan, her eyes full of tenderness and smiles.

"Yuan, you are really my lucky star. You always bring unexpected gains." Li Yuan gently stroked Bi Yao's hair and said softly, "Yaoyao, you are my lucky star."

The two smiled at each other, held hands, and walked into the castle gate.

Li Yuan clenched the key in his hand, and suddenly felt something was wrong...

Inside this castle...

Why is it so dark and there is no sound at all?

He was about to speak when Bi Yao covered his mouth...

The castle gate slowly closed behind the two of them, making a dull echo, as if completely isolating them from the outside world.

Li Yuan held the golden key, but at this moment he felt it was like a hot potato.

The interior of the castle was not as magnificent as they had imagined. Instead, it was surprisingly dark and silent. It was pitch dark, and only some unknown runes on the wall emitted a faint green light, adding a bit of weirdness.

"Yaoyao, this place... is eerie and a bit scary." Li Yuan lowered his voice and unconsciously moved closer to Bi Yao.

He wanted to say, "It's just like the wild area in the canyon," but considering the current environment, he swallowed the words back.

Bi Yao also noticed something was wrong. She gently patted the back of Li Yuan's hand, signaling him not to panic.

"Don't be afraid, I'm here." Although she said this, she was also a little nervous in her heart.

The atmosphere inside the castle was completely different from what she had expected.

The two of them groped forward, taking every step carefully.

"This place...why does it feel like a maze?" Li Yuan had just finished speaking when he suddenly stepped on empty air and fell down!

"Yuan!" Bi Yao exclaimed and reached out to grab it, but only grabbed a piece of clothing.

"Yaoyao... I seem to have fallen into a trap..." Li Yuan's voice came from below, with a hint of panic.

Bi Yao quickly lay on the ground and looked down in the faint green light.

Li Yuan fell into a bottomless pit. The bottom of the pit was pitch black and he could not see anything.

"Yuan, how are you? Are you hurt?" Bi Yao asked anxiously.

"I'm fine, it's just... there seems to be something underneath..." Li Yuan's voice trembled with a hint of fear.

Bi Yao's heart sank suddenly.

She looked around and found that the runes on the wall seemed to flicker more frequently, as if something was awakening...

"Yaoyao...be careful behind you..." Li Yuan's voice suddenly became rapid and sharp.
