The main hall is extremely deep, and it feels like it keeps going further underground.

"It's very wrong, I feel that the previous experience is completely useless here, we have been walking for ten minutes, right?, where does this hall lead?" Shen Mu still carried the Holy Light Bullet to open the way in front of him, and said as he walked.

"Shen Mu, I feel that the aura of the fire element is starting to thicken. Cheng Yanyue suddenly spoke.

"Fire elemental, is there a volcano ahead? There should be no other possibility of a volcano at the depth here. Su Qian glanced at his Flame Demon Twin Blades, and then said, "The Flame Demon Twin Blades seem to be moving a little, and the machine spirit tells me that he has been here, and he is getting closer and closer. ”

"Could it be that Dean Liu has been here before!"

While everyone was speculating, the vision ahead suddenly widened.

The statues on both sides are gone, like a gourd coming to an end. It was a huge space, illuminated by a fiery red glow. It's a crater!

"Shallow, there are spiritual power fluctuations here, be careful. I'll go over and have a look first!" Shen Mu jumped out after taking care of it.

Not long after Shen Mu left, a demon beast attacked, and it was two elemental creatures!

Elemental creatures are one of the most troublesome monsters, as they don't have a fixed shape, and physical attacks are almost ineffective against them.

"Fire elemental creatures, haha, you guys do your defense, leave it to me!" Huang Yixuan laughed, flame is his nemesis. But he's also the nemesis of the flames!

As soon as the ice spell came out, the two elemental creatures instantly lost their combat power and turned into two spirits and fell to the ground. Huang Yixuan was so proud, just after a few words, more than a dozen stronger elemental creatures jumped out of the crater below. Their breath is even stronger!

Huang Yixuan was immediately suppressed by such a powerful fire elemental power, and his hot howl pushed back.

"Yixuan, you stand back, I'll come!" Su Qianqian stared at the shield given by Mu Bai, and the flame demon's twin blades brought out bursts of anger. It turned out that more than a dozen elemental creatures were killed in just one round, and the people around them were stunned.

This Su Qianqian's attack ability is too strong, isn't it? It's already a bit perverted.

Being stared at by several people, Su Qianqian looked a little embarrassed, shrunk to the back of the crowd with a red face and said, "I don't know when I became so powerful, it seems that it is because my weapon has somewhat restrained them, and it seems to be able to absorb the energy of flames?"

Everyone suddenly realized, especially Huang Yixuan directly pulled Su Qianqian and pushed her forward, "Don't say anything, Qianqian, you are responsible for opening the way!"

Cheng Yanyue covered her mouth and chuckled, so beautiful that Xiao Qingfeng happened to witness it, and she was immediately intoxicated.

"Xiao Qingfeng, what's the daze, keep up!" Huang Yixuan immediately reminded someone who fell.

Xiao Xiu and Mu Bai were still guarding the flanks, and several people followed Shen Mu's forward route.

In just a few minutes, you reached the crater rim, and you could see a fiery red color.

In the middle of this fiery red space, a man and a beast are fighting, and it is Shen Mu!

His opponent is quite strong, and if you look closely, it turns out to be a fire dragon!

"Brother Mu, what kind of demon beast is this?" Huang Yixuan shouted.

Shen Mu didn't answer in the fierce battle, but Xiao Xiu took over and said, "I'll help, the strength of this demon beast is already close to that of the Demon Monarch, and this is his home field, it's not easy to deal with, you pay attention to killing the surrounding fire elements, don't let them disturb the main battlefield!"

The black Tiens burst out of purple energy and joined the warband not far away.

With the help of his mount, Shen Mu's attack became more fierce, and the purple fighting spirit gushed out, as if he wanted to compete with the fiery red.

"I can't help at all, my cultivation is too weak, this bit of ice spell is estimated to be weakened by half here, shallow, what good idea do you have?" Huang Yixuan stomped his feet on the spot, and there was no way but to ask for help from Su Qianqian, who was the highest cultivator.

"I don't know how to fly, my cultivation is improving too fast, and my comprehension is not in place. Pastoral Song already knows how to fly and the laws of space, hey, I'm just adding to the chaos when I release my martial arts so far away. Su Qianqian shook his head and said after slashing the fire elemental monster.

Cheng Yanyue is a Fire Spirit Venerable, although this place can amplify the power of her spells several times, but the opponent is not afraid of fire at all, and there is no way.

"Look, there's a small door down here, let's go around and see what's over there?" Xiao Qingfeng poked his head out and seemed to find something.

Everyone was surprised, and hurriedly echoed and looked, there was indeed a swarthy gate under the crater that spiraled down, which seemed to be a passage specially prepared for people. After all, the monster beast is huge, and it must not be able to enter.

After the four of them finished discussing, they decided to take a look.

Mu Bai is a body of energy and is not afraid of temperature. The rest of the people also have corresponding methods, and they all show their magic skills and kill them directly.

Shen Mu's battle was fierce, and he had always been at a disadvantage, so he had no time to take care of the rest of the people. He originally wanted to retreat into the door below, but he really didn't come down to speak and remind. At this time, seeing that everyone intended to do so, he acted very much.

"For minor repairs, you need to resist a few times, otherwise it will be very unsafe under the collapse of the mountain wall. A firm tone came out, and Xiao Xiu knew that the situation was serious, and he also cooperated tacitly.

The Heavenly Lion roared, the beast's power soared, and the buzzing sound of the Iwahime Sword sounded again. Together, they attacked the opponent's fire dragon.

The fire dragon still relied on the excellent defense ability of the scales to resist, anyway, he was not worried at all because of his strong recovery ability after being injured.

"Roar!" several roars followed, and flames mixed with claws came in disgrace.

The sound of collision resounded through the cave, and many little demon beasts exploded and died one after another under the energy flying.

The rest of the team was still covered with a holy blessing shield by Mu Bai, and the situation was okay.

The crater cave is not deep, up and down after a height of more than ten meters. Everyone quickly killed in front of the black gate, but they encountered a problem again.

"This door can't be opened!Grass, it's so hot!" Huang Yixuan's hand pushing the door was almost scorched, and he hurriedly used his magic power to cool himself down.

"I'm coming!" Su Qianqian was not afraid of the high temperature, and directly ran the fighting spirit to push the door, and the black door was still not moving. "It's strange, there is no spiritual power flowing on the door, and there is no keyhole, so it must be opened directly. ”

"Shallow, try to attack, blast him away! Shen Mu is afraid that he won't last long. I could feel that his spiritual power was depleted very quickly. 5 minutes at most!" Mu Bai said in an anxious tone, in fact, he was a little tired while maintaining the shield, but he didn't say anything.

"I'll try!The fire demon roared!" Su Qianqian took a few steps back, the fire demon's twin blades danced, and a fire demon roared out, bombarding the black door with all his might.

"Boom!" There was a loud bang, and the black door was unscathed!

Everyone was dumbfounded, this martial art is so powerful that it is unharmed, so how to break it!

"I'm afraid your attack is of the flame attribute, this gate is covered by high temperature all year round, so it should be immune to your attack. Xiao Qingfeng said coldly, and everyone looked at him in unison, "Hehe, I have an idea, Yanyue and Qianqian continue to heat the gate, and then Huang Shao and I will use an ice attack to break it with one blow!"

This method is not bad, only the top students can think of it.

"Okay!" Cheng Yanyue and Su Qianqian attacked again, and the black gate was still immovable under the attack of the flame attribute.

"Huang Shao! Ready!" Xiao Qingfeng's Ice Phoenix Sword was surrounded by blue fighting energy, and what was brewing was the Ice Phoenix returning to the nest.

"Understood!" Huang Yixuan raised the staff of crystal and began to chant: "Ice condensation form, frozen blade into spear, give me extreme power, freeze the void ice spear, ice fluctuation spear!"

Cheng Yanyue and Su Qianqian immediately retreated. Mu Bai's shield was then given.

"Boom!" After two strong fluctuations, only white mist remained around the black gate, waiting for the fog to dissipate. The gate is powdered.

"It's successful!" Cheng Yanyue applauded loudly, and immediately beckoned Su Qianqian and the others to enter it first.

"Hey, be careful!" Xiao Qingfeng hurriedly reminded, there was an unknown space inside, so he had to guard against it.

"Mu Bai, you take them in to rest first, and I'll cover Brother Mu!" Huang Yixuan gasped and prepared to release the Ice Wave Spear against the fire dragon in the air again.

Although Shen Mu had been suppressed and unable to speak, he continued to pay attention to the situation below. Everyone has already entered the gate, so they don't plan to stay any longer, and they still have an advantage in speed.

Huang Yixuan's ice spear attacked, and after blocking the fire dragon, Shen Mu was finally able to escape.

One person and one rider disappeared on the spot in an instant, and then appeared beside Huang Yixuan, and as soon as he pulled him up, he walked towards the gate.

The dragon broke free from the ice mist, and when he saw his opponent disappear, he erupted in a thunderous rage that nearly collapsed the entire cavern.

......

Inside the dark gate is still an endless tunnel, all the way down, dark and autumnal. But there was no danger.

"There's no danger here for the time being, let's get back to pranayama first. Shen Mu lit up the surroundings, arranged for Mu Bai and Xiao Xiu to protect the Fa, and then began to rest with the five people cross-legged.

"Brother Mu, the combat power you just played is a little scary. This fire dragon looks a little stronger than the previous Bone Spur Mammoth, and it's still on his home turf?" Huang Yixuan consumed the most, but he talked the most.

"Haha, you found out, and I wanted to hide it. In the past two days, my mastery of the laws of space has improved a little, and I don't want to tell you, the strength of the team still needs to move forward steadily, and if the individual ability is outstanding, they can't progress together. Shen Mu said with a smile.

"Hey, Brother Mu, you see when I can be promoted to your Flowing Shadow cultivation, thank God. Huang Yixuan was poor and was slapped by Shen Mu.

"Hurry up, danger may come suddenly, don't fix these things that you don't have. ”

Xiao Xiu's voice came from the side, "A few of you don't look like you have come to practice, you have to learn to rely on the team, what if Shen Mu and I couldn't parry that fire dragon just now?"
