The sword roared, thunder and lightning surrounded, but in a matter of moments the man had already solved a lava stone monster.

It's Gu Changqing!

He's also on the fourth floor.

"Evergreen!" Ji Xian couldn't help but smile, and several people finally gathered together safely.

Ji Xian quickly solved the lava stone monster he was facing, then flew over and solved the remaining lava stone monster with Gu Changqing.

At the moment when the last lava rock monster fell, Gu Changqing jumped forward, and the sword body pierced into the position of the karst stone monster's brain, and with a slight stroke, a red crystal was pulled out.

The two fell to the ground, Ji Xian looked at the red crystal on Gu Changqing's hand, and was stunned: "This is ......"

"What I found by accident, seems to be useful." Gu Changqing said succinctly. He didn't know what it was, but when he reached the fourth layer, he happened to encounter the lava monster awakening, so he fought with it, and when he swung his sword, he cut the head of the lava monster, revealing this red crystal, maybe this thing was useful, so he went all the way to collect it.

The other three also came quickly.

Ji Xian raised his hand, Gu Changqing understood what she meant, and directly threw the red crystal and some of the previously collected to her.

Ji Xian caught the red crystal, observed it carefully, and used spiritual power to test it.

At the head of a Lava Cube......

She seemed to know what this was for.

She looked at Xiao Fengqiu, and Xiao Fengqiu gave her an affirmative nod.

"This is it!" Ji Xian said: "With this, you can dive into the magma." ”

"I see!" Xie Lingxin was surprised.

The fourth layer seems simple, but it is actually difficult.

The first is to judge the difference between the karst stone monster and the karst stone monster outside, and then judge that the thing that makes the karst stone monster mutate and make them clear the level is under the magma, and if you want to dive into the magma, you have to find something that can dive into the magma, and the inertia of people's thinking will subconsciously exclude the mutated karst stone monster.

They had been looking for a long time, and if it weren't for Gu Changqing's mistake, they might still be stumbling on this fourth layer.

Actually, it's really simple, think that the karst stone monster can not turn ash in the magma, then there must be something on it.

Ji Xian shook his head helplessly: "Thinking inertia kills people." ”

***

This entire space was full of magma and karst stone monsters, and it was very fast to dig up those red crystals, but in half an hour, plus a few Gu Changqing found, the red crystals needed by the five people were all together.

Ji Xian was afraid that holding the red crystal in her hand would hinder her battle, and she was afraid that if she accidentally lost it somewhere else, she would be gray, and she couldn't use it when she put it in the storage ring, and she was still entangled.

On the side, Xie Lingxin sneered: "You are stupid." As she spoke, she stepped forward and took the red crystal in Ji Xian's hand, raised her hand and fiddled with her head for a while, Ji Xian only felt that his head was sinking, his hair was tight, and Xie Lingxin stepped back: "Okay." ”

"Won't it fall?" Ji Xian raised his hand and touched it.

"No, it won't." Xie Lingxin said: "Don't you believe me, my hair tying skills are first-class!" ”

"Okay, believe you, believe you." Ji Xian is funny.

The five of them took the red crystals and prepared to dive into the lava.

The magma was red, and it was still bubbling upwards, Ji Xian swallowed his saliva, although he knew that he would be fine, but at first glance it was still very psychological.

Ji Xian couldn't control his brain, if someone came over at this time, he would see them jumping into the magma collectively, maybe he would think that they were committing suicide collectively?

Gu Changqing and Xiao Fengqiu bore the brunt of the jump, sank into the magma, and soon disappeared.

In order not to disperse a few people, Ji Xian, Xie Lingxin, and Feng Shouli also jumped down.

The magma was red, but the scenery could still be seen, it was thicker than the water, and a few people quickly saw Xiao Fengqiu and Gu Changqing in front of them, and hurriedly followed.

"There's aura fluctuations down there." Xiao Fengqiu said.

"That's it." Ji Xiandao.

Going down little by little along the aura fluctuations below, Ji Xian only felt that even with the red crystal, the heat that could not be stopped was coming, and the red in the magma reflected everyone's faces was a little red, which was interesting.

There is no bottom edge in this magma, and it is so viscous that even if you swim, it will be much heavier than on the shore to lift your hands and feet, and it will be extremely laborious.

Something seemed to swim in front of him, Ji Xian was stunned for a moment, and subconsciously raised his hand to grab it.

Slippery and hot, she looked and saw in her hand a fish with a fiery red body and golden wings, constantly struggling.

"Isn't this the goldfin firefish mentioned in the book?" Xie Lingxin saw it and leaned over and said.

Goldenfin firefish, the aura is compelling, the whole body is fiery red, only the wings are golden, I heard Jingyu said, this kind of fish is fresh and tender, and it is most suitable for making soup. Unlike other fish, this kind of fish grows in magma, and it is laborious to catch it, after all, no one below the primordial infant in the magma dares to enter, and which primordial infant will go to the magma to catch fish? However, there are also some magic tools that have been invented to catch fish, but it is not so easy to catch such fish.

Ji Xian looked at the goldfin firefish that was still struggling in his hand, as if he had thought of something, and turned his head to look at Xie Lingxin with a bright eye: "Lingxin, you say, if we take this red crystal out and then go to the magma outside to catch the goldfin firefish, will we be able to make a fortune?!" ”

"Are you hot and stupid?" Xie Lingxin laughed: "Although your idea is indeed practical, but we are still short of this spirit stone?" ”

"Yes." Ji Xian sighed, looked at the goldenfin firefish that was still struggling in his hand, and casually threw it into the storage space: "Just keep this one, find time to see if it's as delicious as Senior Brother Jingyu said." ”

"Okay, call me when you eat." Xie Lingxin said with a smile.

The two followed again.

I don't know how long I swam, the feeling of heat became stronger and stronger, and Xiao Fengqiu suddenly said: "It's here." ”

This is the bottom of the lava, where there are many spirit plants that can only survive in the lava, and there is a white house standing there.

"This is the way to the next floor!?" Feng Shouli was surprised.

"Looks like it's finally going to end, it's all magma, I'm tired of seeing it." Xie Lingxin breathed a sigh of relief.

"But... Aren't we looking for the reason for the mutation of the karst stone monster? Ji Xian asked hesitantly.

"You're going to find it?" Xie Lingxin was surprised.

Xiao Fengqiu suddenly spoke: "Didn't you notice?" ”

"Found what?" Xie Lingxin questioned.

"There are no rewards for this tier." Gu Changqing opened his mouth coldly.

Ji Xian was stunned: "Yes, it stands to reason that there will be a reward for breaking through the first floor, no, the rewards for the first two floors are in that house, and only the rewards for the third floor were given to me by that person, could it be that the rewards on this floor are also in the house?" ”

"You're thinking too simply." Xiao Fengqiu said: "We just found a place to lead to the next layer, and we didn't do anything else, so why should there be a reward?" ”

"Is it possible to find the cause of the mutation of the lava monster?" Ji Xian asked.

"Quite possibly." Xiao Fengqiu said.

Several people suddenly fell into deep thought.

In fact, they are not stupid, but the mood of wanting to leave quickly accounts for most of them, so they didn't think of this, Xiao Fengqiu said this, and they also understood.

Spiritual power fluctuations were still coming from afar.

After straightening out their thoughts, a few people didn't say anything, and went directly in the direction of spiritual power fluctuations.

The place where the spiritual power fluctuated was not far from them, but in a moment, they had already reached the place.

It was a huge red crystal, even in the magma could not bury its beauty, and from a distance, there was a burning light flashing from its body, like a huge treasure.

"This is ......," Xie Lingxin was surprised.

Ji Xian stepped forward and touched the red crystal, which was one person tall, and affirmed, "This is the thing in the brain of the lava stone monster." ”

"That's what the Lava Monster is affected by." Feng Shouli sighed beside him.

Ji Xian's spiritual power was channeled in, and he tried it before he spoke: "There is a strong energy inside this red crystal, which can affect the lava stone monsters outside and change their physique. ”

"That's it." Ji Xian said: "This only has an effect on the lava stone monster, if people get it, it is like we are now, we can swim in the magma at will." ”

The five of them looked at each other, then turned their gaze back to the red crystal.

"Could it be... Is this the reward? Xie Lingxin asked.

"It should be......" Ji Xian was unsure.

Xiao Fengqiu gave a positive answer: "Yes." ”

"How do you take this??" Xie Lingxin was helpless: "The five of us, is it difficult to cut this apart?" ”

"You can try." Gu Changqing looked at the red crystal, and directly took out his sword and gestured on it.

"Hey, wait!" Ji Xian hurriedly stopped: "If you cut this open, its original effect will be gone, won't it be a big loss?" ”

"What then?" Gu Changqing turned his head and looked at Ji Xian expressionlessly.

Ji Xian didn't know what to do, so he could only look at Xiao Fengqiu for help.

What Xiao Fengqiu said was generally right, so when she encountered some things that were difficult to choose, she subconsciously looked at Xiao Fengqiu.

Xiao Fengqiu annotated the red crystal, silent, his eyes were a little hazy, as if he was thinking about something.

After a while, he spoke: "Cut it." ”

Ji Xian twitched the corner of his mouth, he really wanted to cut it.

Almost as soon as Xiao Fengqiu's words fell, Gu Changqing raised his sword and gestured a few more times, and then several swords slashed the red crystals and divided them into five parts of the same size.

Ji Xian stepped forward and touched the red crystal he had been given and put it into the storage ring.

The others also took back their share, and several people took it away again.

After taking the reward, the group went the same way to the white room, ready to go to the next floor.

The next level of unknown levels, everything more difficult is still waiting for them.
