"Brother Ye Fan, why don't you go to cultivate?"

Team Leader Chen couldn't help but be a little curious.

"Brother Chen, what I just heard from you, this igneous cave seems to have more than one floor?"

"Yes, there are three floors in this igneous cavern, and the further down it goes, the higher the temperature, and of course, the further down it goes, the more dense the concentration of fire energy becomes. Let's just say that the concentration of the fire vitality in the first layer is only three or four times that of the outside world, but the concentration of the second layer is seven or eight times that of the outside world, but the temperature of the second layer is very high, even if we go down, it will be difficult to bear, let alone them rookies, so the average martial artist chooses to break through the bottleneck in the first layer, and no one dares to go down to the second layer. ”

Hearing this, Ye Fan's eyes lit up, but he thought in his heart: "It seems that mine has gone to the second layer." ”

Thinking of this, Ye Fan asked again: "By the way, Brother Chen, what is the situation on the third layer?"

"The concentration of fire energy in the third layer is even higher, equivalent to fifteen times that of the outside world. Of course, the temperature there was also higher, and only the martial artists of the Nine Realms of the Bitter Sea could barely bear it. In fact, even they didn't dare to stay on the third floor for a long time, at most two or three days. Because after breathing the hot air there for a long time, it is very likely that even the lungs will be burned, and that is not an internal injury that is easy to heal! Brother Ye Fan, why are you asking this? Do you want to go to the second layer?"

"That's right! The concentration of fire energy in here is not high enough, I want to go to the next layer to take a look. Ye Fan didn't want to hide it. Chen and Liu didn't feel very surprised, with Ye Fan's strength, they were indeed qualified to go down and explore.

"Judging from the strength of the Ye Fan brothers, they can indeed go down and find out. However, I would like to remind Brother Ye Fan that you must not stay on the second floor for too long, so as not to burn your lungs. Team Leader Chen kindly reminded.

"Thank you Brother Chen for reminding me, little brother knows!"

After speaking, Ye Fan said goodbye to everyone and walked to the second layer alone.

The passage of this igneous cave winds down to the ground, and the further you go, the higher the temperature.

Ye Fan passed through a long, downhill passage and arrived at a flat passage, where the temperature was very high.

Ye Fan only stayed for a while, and he was sweating profusely, and even his hair was a little curly from the high temperature around him.

But in this passage, the fire vitality is also extremely rich, about seven or eight times that of the outside world.

Ye Fan activated the "Easy Formula", let the meridians in his body automatically operate, and began to absorb this fire vitality.

From the previous conversation with Team Leader Chen, it was learned that even the Bitter Sea Warriors couldn't stay in the second layer for a long time, not because their skin couldn't withstand the heat, but because people's lungs couldn't withstand the hot air here.

After all, human internal organs are the most vulnerable.

In fact, not long after Ye Fan left, Team Leader Chen and Team Leader Liu also discussed with each other.

"Team Leader Chen, how long do you think Ye Fan can stay on the second floor?"

"This....less than two days, I see that although Ye Fan is very strong, after all, he is still a cultivator of the Bitter Sea Dual Realm, I think he can hold on for three days and reach the sky!"

"yes, it's great that he can hold out for three days, so let's wait and see how many days he comes up." ”

At the same time, Ye Fan had already begun to cultivate hard at the second layer.

A day later, Ye Fan stood up without hesitation and headed towards the third floor.

When Ye Fan reached the third layer, he quickly found that the temperature inside was terrifyingly high, and the scorching air was burning on people like a soldering iron.

"Fortunately, my ** is very strong, I'm afraid that the Liantai martial artist can't compare to my **, so I can barely withstand such a high temperature. Ye Fan thought happily in his heart.

"As long as I hold my breath, I think I'll be able to stay here for a long time. The concentration of fire vitality here is really good, at least fifteen times that of the outside world, and it is many times stronger than that first layer. ”

Thinking of this, Ye Fan couldn't help but feel a little happy in his heart.

At that moment, Ye Fan no longer hesitated, and began to break through the retreat on the third layer.

Time flies, and in the blink of an eye, four days have passed, plus Ye Fan has spent one day on the second floor.

It had been five days since Ye Fan left the first layer.

Ye Fan and Chen Liu, who had been waiting on the first floor, also began to worry.

"It's been five days, why hasn't this Ye Fan come up yet?"

"Yes, in five days, I think it will be difficult for even the Bitter Sea Martial Artist to hold on for so long in the second layer, do you think this Ye Fan will have an accident below?"

"It's hard to say, or I'll go down and have a look!"

"Okay! Go down and take a look!"

"Okay, I'll go!" Team Leader Chen immediately went to the second floor to look.

After about a cup of tea, Team Leader Chen rushed back.

"How is that? Is that Ye Fan okay?"

Team Leader Chen shook his head silently, and after a while, his face was strange and said, "I didn't see Ye Fan's shadow at all on the second layer. ”

"What? You didn't see Ye Fan on the second floor? It's so hard that he went to the third layer? This can't be!"

Team Leader Chen also looked incredulous, and only after a while did he slowly shake his head: "I don't know! My strength is too weak, so I don't dare to go down to the third layer." However, there is only one exit from this igneous cave, and we haven't seen Ye Fan come up, so I think he probably went down to the third floor. ”

Team Leader Liu suddenly gasped: "If Ye Fan really went to the third layer, how could this be possible?, could it be that he is a Lotus Stage Martial Artist?!"

Team Leader Chen also pondered with a puzzled face.

Then another day passed, and on the sixth day.

On this day, the fire vitality of the third layer suddenly rioted, forming a huge vortex of vitality that frantically poured into Ye Fan's body who was in retreat. At this moment, if there are outsiders present, they must know that this is a sign that the bottleneck is about to be broken.

Ye Fan greedily absorbed the furious fire energy around him. After a long time, his whole body shook slightly, he slowly opened his eyes, crying and laughing, he did not break through. The spiritual power of his bitter sea was obviously saturated, why did the spiritual power in his whole body always disappear at the last moment, he had no choice but to get up and walk along the passage to the depths of the third layer.

Soon, he came to the end of the third layer, Ye Fan found nothing, and he didn't find anything at all.

Ye Fan smiled bitterly in his heart, and began to return the same way.

After walking back about thirty meters, Ye Fan suddenly stopped and looked at the side of the cave wall with a puzzled gaze.

Then he pressed his ear to the stone wall, and he faintly heard the sound of the air flowing from behind the cave wall, mixed with the sound of 'rustling'. These voices were extremely small, and it was difficult for ordinary martial artists to find them, Ye Fan had let go of his mind, so he heard them by chance.

"There is a sound of air movement behind this stone wall, which means that there is a passage behind this stone wall, is there still space behind this stone wall?" Thinking of this, Ye Fan suddenly became curious, and slammed his fist towards that stone wall.

It took a lot of effort to split the thick stone wall, revealing a hole that could only be climbed down by one person.

Ye Fan looked into the empty hole, the hole was crooked, and he couldn't see what was going on under the hole, but he could feel a wave of heat rushing towards him, and its temperature was higher than that of the third layer.

"I didn't expect that there was a fourth layer in this igneous cave, and this passage should lead to the fourth layer. ”

At this time, Ye Fan heard a strange rustling sound from under the hole, and these sounds were extremely subtle.
