There was a bronze mirror in front of Hongying's body, and the yellow light of the mirror flickered, which actually showed the image of Yu Feifan killing several demons.

Her face revealed a dignified look, she didn't expect Yu Feifan's cultivation to be so profound, obviously she was also a Guiyuan Realm cultivator, but killing the same level was like chopping melons and vegetables. Hongying's expression was full of strangeness, and even her face, which was slightly weak at first, was full of a hint of evil.

After Yu Feifan killed the demon, he immediately walked into the wooden house. The moment he stepped into the wooden house, a flying sword quickly stabbed into his eyebrows, and there was a great momentum that would kill him.

The Heavenly Demon Sword shook slightly, and immediately slashed the flying sword to the side, and with a finger of his right hand, a green silk that was unrecognizable to the naked eye quickly tied up a young monk with a panicked face.

"Don't move, as long as you move a little, your body will be cut off several times. Yu Feifan's heart moved, and the phoenix spirit silk that was bound to the young monk's body immediately shrank.

"Fellow Daoist, stop, you are a monk sent by your family. I can give you the key, and I haven't had time to study that vault yet. The young monk shouted in horror as soon as he was restrained.

Yu Feifan's heart moved when he heard this, and his eyes looked at the stone table in the room, on which were placed some scroll classics, as if he was consulting something.

"What are you doing?" Yu Feifan wondered in his heart, this person didn't seem to be as Hongying said to be made into a demon slave.

"I am,"

"Brother Feiyu, I finally found you. Just as the young monk was about to speak, Red Ying rushed in, and he walked up to the young monk and said, "I have come to rescue you on the orders of the elders of the family, and the elders have ordered that as long as you bring back the secret key, the clan will definitely reward you." ”

The young monk's face changed sharply when he saw the woman, and deep fear appeared in his eyes. Although he quickly covered it up, he couldn't escape Yu Feifan's eyes.

"Daoyou, put him down, the secret place you need needs the secret key on Brother Feiyu's body, otherwise even I won't be able to open it. Hongying smiled and said to Yu Feifan on the side.

The young monk's eyes swept back and forth on Yu Feifan and Hongying, his expression was full of hesitation, but after seeing Yu Feifan's cold eyes, he gritted his teeth and took out a key from his body.

The three of them quickly left the wooden house, and in order to avoid being discovered by the demons, the three of them did not choose to fly away, but used the art of indulging to shuttle back and forth in the back mountain.

Yu Feifan walked in front, followed by Hongying and Li Feiyu, none of the three seemed to say a word, and soon stopped in front of a cave.

"This is it. Hongying stood in front and said with some excitement, this forbidden place has only been passed down by the heads of the family for generations. And you can't find it without a secret key.

Hongying did not hesitate and quickly entered the cave, Li Feiyu hesitated for a moment and finally chose to enter.

Yu Feifan looked at the two people who entered, and the corners of his mouth curled: "It's interesting!" He hesitated for a moment and then followed.

Hongying inserted the key into the Dharma Gate, and the bare stone wall in front of her immediately cracked a portal.

"Let's go!" she didn't hesitate, and as soon as her figure moved, she dodged in.

After Yu Feifan followed Li Feiyu in, the portal behind him was closed again with a flash of inspiration.

"I didn't expect this to be a Vault. Yu Feifan looked at the dense various materials on the shelves in front of him, and was really shocked in his heart, is this the strength of the family?

In addition to the materials on the shelves, there are also sealed wooden boxes, and there must be many strange things sealed in these wooden boxes.

"Do you think this place is private enough?" Hongying said suddenly, both in tone and momentum, completely different from outside.

Li Feiyu stood in the corner like a person who made a mistake, neither daring to approach Yu Feifan nor Hongying.

"Daoyou is really a trustworthy person. Yu Feifan didn't seem to notice the abnormality of the red tassel, and said with a faint smile.

"Is it? Daoyou is satisfied!" The corners of Hongying's mouth curled and sneered, and a powerful mana suddenly erupted from his body, and an extremely slender soft sword stabbed at Yu Feifan's heart as quickly as a spirit snake.

With such a fast speed and such a close distance, not to mention the Returning Yuan Realm, even the cultivators of the Evil Realm would not be able to dodge this fatal blow. Almost at the moment when the soft sword pierced, the same blue sword flew out of Yu Feifan's body, sending the red sword flying. Yu Feifan's body took the opportunity to explode backwards.

"You are indeed a monk in the realm of evil. The dripping sword above Yu Feifan's head kept hovering, staring coldly at the woman opposite, "Even the name Hongying is fake." ”

"Do you know I'm a cultivator?" the woman exclaimed.

"It's just speculation, you are the head of the Li family, this is a traitor to your Li family, you are for him, no, for this secret treasure deliberately infiltrated the Demon City. You're pretending to be subdued by the demons, but you're just trying to sneak in. ”

"Oh, do you know that in detail?" the woman was really surprised this time, this person actually saw through everything.

Yu Feifan shook his head: "Even if I guess, I can't know so clearly, these are just what you told me." ”

"We tell you, will you be able to hear the voices between us. Hongying's expression changed, and his eyes looked Yu Feifan up and down vigilantly, but no matter how he looked at it, this person was a Returning Yuan Realm monk with demonic energy.

Her face was a little ugly, and her voice was hoarse, "It seems that I underestimate you a little, a Guiyuan Realm monk can actually hear my transmission, it seems that you are not an ordinary person, if it were in normal times, our Li family might make you a friend, but now ......"

"With so many secrets, how could it be possible for an outsider to know about them. Yu Feifan seemed to know what the other party was going to say.

"Yes, this is the foundation of our Li family, with these resources, our Li family can make a comeback elsewhere. ”

"You can take all these treasures with you, all I need is this hiding place where I can hide from the demons. ”

"You're right, but I can't trust you, and I can't take this vault with me. ”

Yu Feifan sighed slightly: "Daoyou wants to kill me!"

"That's good!" Although Hongying said this, she didn't mean to do it immediately, Yu Feifan gave him a feeling that was too weird, a mere Guiyuan Realm had no fear in the face of himself, and he knew his identity or followed in, these unreasonable behaviors boiled down to only one reason, if it wasn't for the broken brain, it was because he was very confident in his own strength.

"Aren't you afraid of recruiting people from the Demon Clan?" Yu Feifan said with a flash in his eyes.

"You also underestimate our Li family's secret storage, this place is built with special materials, and there are more than 20 prohibitions on the stone wall, even if we demolish this place, we won't know what happened. As soon as Hongying's voice fell, her mana rose and she was about to make a move, and Li Feiyu, who was standing in the corner, suddenly walked up to her and said, "The head of the family will hand over a Guiyuan Realm monk to me, and it will also give me a chance to make up for it." ”

"You, are you his opponent?" said Red Ying disdainfully, as if looking at a dead man.

"I was just careless just now to give him a chance, and this time I will definitely kill him. Li Feiyu said firmly.

"Well, since you want to try it, let's do it. Hongying obviously wanted to kill him with the help of Yu Feifan's hand, in fact, she would never let Li Feiyu live. This is also another purpose for her to infiltrate the Demon City. It's just that I didn't expect to meet Yu Feifan halfway, and things went so smoothly.

Just when Hongying was proud in her heart, Yu Feifan's words frightened her.

"Do you really think I can hear you?"

"What? What did you say?" Hongying's heart suddenly became horrified, if Yu Feifan hadn't heard his own transmission, then how did he know what he said.

"Not good!" Almost at the moment when Hongying spoke, Li Feiyu beside her moved, and a dark red talisman in her hand instantly hit Hongying's body, and then her body quickly flew out diagonally.
