The Hehuan Sect cultivates alchemy; my senior sister helps me refine alchemy throughout the world.

Upon hearing the words "Demon's Lair," Shen Yifei couldn't help but feel a little worried. Ye Ling had just killed three thousand demons and was almost exhausted; the lair must contain even more demons, and they must be much stronger.

Seeing his expression, Ye Ling sneered, "What, scared? Don't dare to go?"

Shen Yifei thought to himself, "Is it because this woman thinks I'm not tough enough that she's mocked me so many times today?"

He straightened up. "What's there to be afraid of? With a senior like you here, what am I afraid of!" Shen Yifei then felt that this was too vulgar, so he quickly added, "What I mean is, with a senior like you here, those demons are nothing but chickens and dogs."

Ye Ling snorted, "Then come with me!" and turned to walk into the depths of the valley.

Shen Yifei turned back and shouted into the cave, "Elder Lin, wait here, I'll be right back!"

Lin Ruonan poked half her head out of the cave and watched as Shen Yifei followed the blood-covered killing god and disappeared in a flash. She was filled with anxiety.

Is this Sect Master Shen human or demon? How come he's so familiar with the legendary Demon God of War?

The Palace Master is so familiar with him, and stayed at Cangwu Mountain for half a month. She should know his background.

If it's a demon, why get so close? Xuanbing Palace has also joined the Demon Extermination Alliance, and the Palace Master is the Vice Alliance Master.

Lin Ruonan was racking her brains. She had no idea how these high-ranking figures would choose or what decisions they would make. As a middle manager, she could never guess.

She could only obediently lead her disciples to huddle in the cave, praying that this man would return safely. With him around, she felt very safe.

Shen Yifei followed Ye Ling, rushing deeper into the secret realm.

Ye Ling was incredibly fast. Covered in blood, she moved like a red lightning bolt through the hazy secret realm. Shen Yifei struggled with all his might to keep up with her.

The two walked through ruins and crossed several barren mountains. Suddenly, Ye Ling stopped and turned around.

Shen Yifei hurriedly tried to stop himself, but he couldn't!

He crashed headfirst into Ye Ling's chest, his eyes, nose, and mouth burying themselves deep inside.

Shen Yifei was in an awkward situation; it seemed as if he had deliberately taken advantage of the other person.

However, Ye Ling simply reached out and pulled him from her chest, like pulling out a radish, and casually pushed him aside.

"So impulsive and unsteady!" Ye Ling rubbed her chest; the impact had been quite severe.

Shen Yifei chuckled twice, "Senior, I didn't mean to. You were too sudden. I couldn't stop myself."

Ye Ling rolled her eyes at him and pointed to a city not far ahead. "We're here."

The two flew quickly toward the city. Ye Ling flew much slower, and Shen Yifei didn't dare to follow behind, so he flew alongside her.

The demon soldiers guarding the gate spotted the two from afar.

A demon who looked like a leader, carrying a large sword, shouted, "Halt! Who goes there...wait a minute? What's this beauty? Where are you hurt? Want me to bandage you up?"

Ye Ling didn't speak, but just gave a cold laugh.

Shen Yifei watched from the side, thinking that this devil leader was probably in for some bad luck.

Sure enough, Ye Ling stretched out her hand, and black energy condensed in her palm, instantly forming a black spear.

The demon leader's smile froze the moment he saw the spear.

"This...this is..."

Before he could finish speaking, the gunshot wound had already pierced his throat.

With a flick of her wrist, Ye Ling sent the demon leader's head flying, exploding in mid-air, and spurting blood three feet high from his neck.

Before the remaining demon soldiers could react, Shen Yifei had already rushed forward, wielding his Long Sky Sword and killing three demon heads in one strike, sending them flying into the sky.

In just a few breaths, the two dealt with dozens of demon soldiers on the city wall.

The scene inside the city surprised Shen Yifei.

This is a typical fortress, with barracks and warehouses lining both sides of the street. In the center of the fortress is a huge square where thousands of demon soldiers are gathered and training.

A demon resembling an officer, riding a demonic wolf, spotted the two blood-soaked figures in mid-air and immediately raised his horn.

"Waaah...waaah..."

As soon as the horn sounded, the entire fortress erupted in chaos.

The thousands of demon soldiers on the training ground all looked up, saw the two, and charged towards them with howls.

Demon soldiers continued to rush out from the barracks on both sides of the street.

"Well done!" Ye Ling sneered, her figure blurring as she charged directly into the horde of demons.

Shen Yifei followed closely behind, wielding his Long Sky Sword, a black sword aura cleaving the dozen or so demon soldiers in the front row in half. The little monster also darted out, howling as it pounced on the demons.

For it, this was a feast.

With a single sweep of her spear, Ye Ling sent dozens of heads flying into the air. She then pierced the chests of two demon generals, tossing their corpses aside, which then crashed down on another group.

Although demons are not afraid of death, fighting them like this is no different from suicide.

With each swing of Shen Yifei's Breaking Army Sword Technique, a group of demons were taken away. The Breaking Army Sword Technique grew stronger and stronger, and the killing intent became more and more intense!

Within moments, a large number of demon soldiers had fallen. The remaining ones finally began to fear and retreated in droves.

Seeing that things were not going well, the officer riding the demon wolf turned around and ran deep into the fortress.

"Trying to run?" Shen Yifei swept aside the demon soldiers blocking his way with his sword and chased after them. The little monster followed closely behind.

The officer rode the demon wolf at breakneck speed, Shen Yifei chased closely, but the little monster ran even faster.

A dark shadow flashed by, and the wolf beneath the officer let out a miserable howl, its front legs buckling as it collapsed to its knees.

The officer fell off the wolf's back, and before he could even get up, Shen Yifei's sword was already at his neck.

"Tell me, who sent you to arrest me?" Shen Yifei asked.

The officer stared at Shen Yifei with bloodshot eyes. "You...you're Shen Yifei?"

"It was me. Tell me, who sent you to kill me?"

The officer grinned, revealing a set of fangs. "You...you're dead! They won't let you go!"

After he finished speaking, his body began to swell.

Having learned his lesson once, Shen Yifei was determined not to fall for it again.

The officer's body was instantly ignited by black flames. The effect was multiplied by the addition of demonic energy, and the black flames engulfed the officer.

The officer screamed a few times, then his whole body melted like a candle, finally turning into a pile of ashes.

Suddenly, another urgent horn sounded in the distance, and the demon soldiers who had been trying to retreat rushed forward again upon hearing the command.

The demon soldiers surged toward the two in droves, growing from a few thousand to nearly ten thousand!

Shen Yifei was caught up in the killing frenzy, and rows of demon soldiers fell, with others quickly replacing them.

The little monster didn't have time to eat; it could only bite its way down the path.

"Ah... my egg..."

"Holy shit..."

Ouch and curses rose and fell.

But there are just too many demons.

Shen Yifei had lost count of how many he had killed; he only felt his arms were aching.

He looked up and saw that the entire fortress was teeming with demons, a dark, swarming mass, like an endless swarm of locusts.

Shen Yifei discovered that he and Ye Ling had been separated by the demon, and Ye Ling was also desperately trying to hold on, eating one demon pill after another that Shen Yifei had given her.

Those few bottles of magic pills don't look like they'll last much longer.

Seeing the surging demons, Shen Yifei had a sudden inspiration: refining the demons into pills would be perfect for replenishing Ye Ling's magic power!

Heh... Taken from the devil, used for the devil!
