"Boom! Rumble! Rumble! Countless pillars of fire rose into the sky, scorching the sky red, and magma scattered in mid-air, and soon the volcanic islands that were nestled in the sea of lava began to erupt one after another, and the earth began to tremble, and the air began to twist, and all the scenes became blurred.

Mu Yun took Zhan Qing to teleport dozens of times in a row, and finally escaped from this extremely irritable sea of lava and fire, but in other parts of the sea of fire, some small bulges began to appear on the surface of the sea, which were the predecessors of those bulges that broke out, Mu Yun's eyes stared at the sea, and his face gradually became solemn.

"Mu Yun, what's wrong?" An Zimo flew from a distance, he saw that the two of them were safe and sound, he breathed a sigh of relief in his heart, he followed Mu Yun's gaze and looked at the sea, "What are you looking at?" Is there something wrong? ”

Yu Haoxuan flew up from a place close to the sea at this time, and said very strictly: "The resentful spirits in the soul mound seem to be about to riot. ”

"It's not like, they've already rioted," Mu Yun continued, "When I rescued Brother Zhan Qing just now, all the resentful spirits in the sea of fire there blew up the True Yuan, and those pillars of fire that you saw were the effect of their self-detonation. ”

"Aren't they killing themselves?" Zhan Qing stared at Mu Yun very curiously, "What is the purpose of them doing this?" ”

"I don't know," Mu Yun shook his head and said, "But I think there is one person who will definitely know the way." ”

"Who?" Zhan Qing, An Zimo and Yu Haoxuan asked in unison.

"Naluo Wang Ying Shaoqing!" Mu Yun replied, "He is the owner of this soul mound, and he should naturally be very clear about everything that is happening here." Hearing this, the three of them nodded in unison.

"Mu Yun, you go to the Naluo King as soon as possible," An Zimo pondered for a moment and said, "I always have an ominous premonition, as if something big is going to happen, and it is best for us to find your friends as soon as possible and leave the underworld as soon as possible." ”

"Hmm!" Mu Yun nodded emphatically.

In the soul mound, the sky that was originally dusk began to gradually turn a little red, and the temperature in the air was gradually rising, and the huge body of the castle of Naluo King Ying Shaoqing began to float from the island, rising from the ground with the sound of "boom".

The four of Mu Yun came to the castle at this time, looking at the strange scene in front of them, and couldn't help but have a question in their hearts, "Subordinate night owls, ask to see Lord Naluo!" Mu Yun shouted at the castle.

"The night owl girl doesn't have to be formal," said the voice of King Naro from the direction of the castle, "you have come just in time, I need your help with something, let's go to the castle first." ”

"Crunch!" As soon as King Naluo's words fell, the gate of the castle slowly opened outward, and then two teams of demonic beasts and manticores flew out, neatly arranged on both sides of the gate, they all bent their two front legs towards Mu Yun, and their proud heads were also slightly lowered at this time, as if they were greeting the master, Mu Yun and the four of them glanced at each other, and then slowly flew towards the gate.

As soon as she entered the door, a beautiful and hot girl in red greeted her, and the girl's eyes swept around the faces of the four people, and finally fell on Yu Haoxuan's face, she smiled at Yu Haoxuan affectionately, and said in a coquettish voice: "Yu Gongzi and the night owl girl, please come with me, and the other two please go to the living room to take a nap for a while." Saying that, she waved at a side door in the hall, motioned for Zhan Qing and An Zimo to go over, and then said to Mu Yun: "His Royal Highness King Naluo has been waiting for the two of you for more than a long time. ”
