"This is just a preliminary estimate, but there are still some things that may happen, maybe, in advance, so you improve your strength as soon as possible, the sooner the better."

Murong Qingchu's always cold and elegant face was never more solemn, and his beautiful voice was as clear as a sweet spring.

"I see."

Mu Ruyue nodded and said, "Murong Qingchu, take me to the eighteenth layer of purgatory......"

The eighteenth layer of purgatory is on top of a volcano not far from the Northern Demon Palace, this volcano erupts hot rocks all year round, and the surrounding area is extremely dangerous, so it is obvious that few people will set foot here.

"The eighteenth layer of purgatory is in the sea of fire, this is the key, you can go down by yourself, I am not worthy of you."

Murong Qingchu took out a key that was arm-long from the space ring and put it in front of Mu Ruyue, and said with a shallow smile: "I think you should have a way to get in." ”

Mu Ruyue nodded slightly, took out a Fire Fighting Pill from the space and took it, took the key and jumped into the sea of fire, and soon disappeared into the man's cold eyes......

Hot!

Now Mu Ruyue only felt surrounded by a stream of heat!

Even with the effect of the Fire Fighting Pill here, she still felt the heat that could burn her to ashes......

"The sea of fire is so big, I don't know where the gate of Purgatory is."

Mu Ruyue groaned for a while, and a trace of contemplation flashed in her eyes.

At this moment, the key she held in her hand emitted a faint light, and the golden light illuminated the entire sea of fire, as if it was guiding her path......

"Should it be there?" Mu Ruyue's heart moved, and she hurriedly swam forward.

Suddenly, she stopped her movements, looked ahead, and landed on the group of fiery red scorpions, her eyebrows suddenly constricted.

"That's ...... Flame Scorpion? Moreover, the ones with the smallest strength are all Lingyuan, and a few of them are in the supreme realm......"

Mu Ruyue's breathing stagnated slightly, who would have thought that there were so many dangerous demonic beasts hidden in the sea of fire?

But while Mu Ruyue was pondering, those flame scorpions seemed to discover her existence and quickly crawled towards this direction.

Their speed was extremely fast, and they quickly arrived in front of Mu Ruyue......

"In other places, if you face so many enemies at once, it may take some effort, but this is the sea of fire, which is what I am best at."

Mu Ruyue slowly raised her hand, and in an instant, a big sword appeared in her palm, and at this moment, all the flames gathered towards her, forming a strong flame storm on the sword.

Rumble!

With a wave of the big sword, the flame storm quickly slammed into the scorpions that were crawling, even if the scorpions were all fire attributes, they couldn't withstand such an impact, and after a loud bang, they all fell to the sky in all directions.

The survivors stood timidly and did not dare to step forward.

Mu Ruyue put away the Nine Heavens Dragon Flame Sword, and did not kill all the scorpions, they did not step forward, and she did not take the initiative to attack them......

"Since the Flame Scorpion has appeared here, it means that it is not far from the Gate of Purgatory."

She quickly swam past the scorpions, heading in the direction of the key, and the scorpions wanted to go up to stop them, but after thinking of her strength just now, they couldn't help but flinch a little......

Soon, the huge door was reflected in Mu Ruyue's eyes.
