"What the hell is that key, I just heard you say that there are still four left, do you already have a key?"

At this moment, Lu Wushuang suddenly asked.

"Well, I do have two keys. Do you remember the mysterious old man we met in that cave? The bronze plaque that the old man reminded us to find was the key. ”

Lu Yan said lightly.

"Oh, I see what you mean, is that it?"

Hearing Lu Yan's words, Lu Wushuang showed a hint of abruptness, and then took out something from his arms and asked.

The thing on Lu Wu's hands was the bronze medal of the six-pointed star.

Lu Yan's eyes lit up, and then he asked, "Why do you have this thing too?"

"Haha, this is what I accidentally met after falling into that cave with Yuehua before, I felt familiar at that time, so I took it, who knew that it was a coincidence that this was the key!"

Lu Wushuang said happily.

"That's great, so we're three keys away, and if we look closely, we should have a chance to find them. ”

Looking at the key in Lu Wu's hands, Lu Yan suddenly had a trace of expectation in his heart, and then smiled excitedly.

"No, no, I think there's still one missing!"

At this moment, Lu Wushuang suddenly shook his head and said with a smile.

"What do you mean? Do you still have two in your hand?"

Until this moment, Lu Yan was already a little excited in his heart, and hurriedly asked.

"Mm-hmm, I got three of them!"

Lu Wushuang smiled a little smugly.

"Haha, that's great, that's just one piece missing!"

At this time, Lu Yan's mood could no longer be expressed in words.

"There's one left, so let's split up and find it!"

At this time, Lu Wushuang also faintly felt a trace of excitement, the mountains and rivers turned around, and he originally thought that there was no chance, but who knew that things had taken a big turn all of a sudden, which made Lu Yan and the others excited.

"I think I have one too. ”

Rumble!

At this moment, Lu Tianqi, who had been silent, suddenly said earnestly.

"What, Tianqi, you also have one here?"

Lu Yan looked at Lu Tianqi in disbelief.

"Well, I found it in that place too. ”

Lu Tianqi answered softly, and then took out a clear green bronze medal from the space ring, which was a six-pointed star bronze medal.

"Damn, this luck is simply against the sky! It seems that all this is providential, and even God is helping us!"

Lu Yan couldn't help but shout into the sky.

"Haha, I'll just say that you are unlucky, now it seems that God is really helping you! Hurry up and take the key to open that lotus platform and refine the heart of the world!"

Lu Wushuang was also excited in his heart, and hurriedly urged Lu Yan to act quickly.

"Good!"

After Lu Yan took the six-pointed star bronze medal from Lu Wushuang and Lu Tianqi, he flew towards the lotus platform again.

After coming to the lotus platform again, Lu Yan took a deep breath, and then began to calm down the excitement in his heart, calming himself down.

After about a few seconds, Lu Yan finally kept himself in a calm state before carefully putting the bronze medal into the remaining groove.

Tick tick!

When all the bronze medals were put into the groove, Lu Yan stared closely at the movement on the lotus platform, and the sweat that flowed out of the nervousness continued to drip onto the ground, making a crisp sound.

Lu Wushuang and the others outside also stared at the lotus platform with nervous expressions.

Rumble!

At this moment, a loud bang suddenly attracted everyone's attention, and they saw that Lu Yan was falling to the ground at this time, and the lotus platform had been torn apart by the explosion.

At the same time, the entire Emperor Killing Secret Realm suddenly shook, and all the demon beasts were frightened and strung around.

The smoke cleared, revealing the true situation inside. I saw that the Heart of the World was quietly suspended in mid-air at this time, and its appearance had no protective film.

"It's done!"

Lu Tianqi couldn't help but exclaim.

Lu Yan's face also showed ecstasy, and he immediately flew into the air and grabbed the World Heart in his hand.

The moment he started, Lu Yan only felt a warm and jade-like coolness coming from the palm of his hand.

"Hurry up and refine it, Lu Yan!"

Lu Wushuang below hurriedly shouted at Lu Yan in the sky.

"Well, you help me protect the Fa, I'll refine it now!"

Lu Yan nodded lightly and then fell from the air.

"By the way, Ruoxi, how should I refine the heart of this world?"

After falling to the ground, Lu Yan realized an embarrassing problem, that is, he didn't know how to refine it.

"I don't know much about how to refine the heart of the world, but I have read some of them in the family books by chance. One is that the warrior directly swallows the heart of the world and then forcibly refines and absorbs it in the body, but this method is easy to cause an explosion and cause the warrior to die. The second is that the martial artist divides a trace of spiritual power into the heart of the world for refining, but the heart of different worlds will have different requirements for the spiritual power of the refiner, and if the ability is not enough to forcibly refine, it is easy to make the martial artist mentally confused and eventually become a madman. ”

Qin Ruoxi said calmly.

"Hey, there is still such a requirement for refining this thing, so there is no other way?"

After listening to Qin Ruoxi's words, Lu Tianqi couldn't help but gasp.

"I know that there are two ways at the moment, and I don't know if there are other ways, maybe there is, maybe not. But in the same way, the benefits of refining the heart of the world to the refiner are also very obvious, at least it can make your strength skyrocket instantly, and all the resources of the entire secret realm are owned by the refiner, and even the martial artist can use the secret realm to fight the enemy!"

Qin Ruoxi said calmly again, to be honest, he also hoped that Lu Yan would succeed in refining, because she had never seen such a situation.

Since everything happened so smoothly, I believe that I will be able to refine it!

Lu Yan was much more relaxed at this time. After all, Qin Ruoxi also said that if he could refine the heart of the world, his strength would also be able to get a huge breakthrough, so he was willing to try to win it.

"But Lu Yan, this is too risky, if something goes wrong, it will outweigh the losses!"

Lu Wushuang was a little hesitant at this time, on the one hand, he hoped that Lu Yan would be able to refine the heart of the world, and on the other hand, he was worried that something would happen to him. This ambivalence made him feel very hesitant.

"Yes, Lu Yan, it's not too late for us to take the Heart of the World with us first, and then refine it when we find another way, or when you are stronger. ”

Lu Tianqi also recognized Lu Wushuang's words, after all, although Lu Yan's strength had broken through now, he still didn't have much confidence in refining the heart of the world.

"No, if you don't have the Heart of the Refining World, you can't take it away, because before refining, it is still closely connected to this secret realm, unless you can take the entire secret realm with you!"

At this moment, Qin Ruoxi said suddenly.

"Okay, since Ruoxi has already said so, everyone also understands that if we can't refine the heart of the world, we won't be able to take it away at all, and we won't have any chance in the future! ”

Just when Lu Wushuang wanted to persuade again, Lu Yan said directly.

"Okay, then you pay attention, if you can't do it, then give up decisively, you are the hope of our family's rise! If something goes wrong with you, then we really don't know how to explain to our ancestors!"

Lu Wushuang grabbed Lu Yan's shoulder and solemnly instructed.

"Rest assured, I know what to do. You can wait by the side with peace of mind. ”

Lu Yan said with a relaxed expression.

Lu Yan quickly sat down, and then quickly fell into a realm of no self and no other.

He tried to follow the method Qin Ruoxi said, and separated a trace of spiritual power as thin as a hair and drilled into the heart of the world.

"Bang!"

As soon as that trace of spiritual power entered the heart of the world, it was crushed by an invisible force, but it also made Lu Yan find a glimmer of opportunity, that is, if his spiritual power was strong enough, he could resist that invisible force.

Lu Yan's calm breath once again separated a spiritual force that was dozens of times stronger than before and entered the heart of the world, this time the resistance he encountered was even stronger, but it was not like the first time when he collapsed.

Lu Yan was overjoyed in his heart, and then accelerated the output of his spiritual power, constantly resisting the repulsive force.

With the passage of time, Lu Yan's spiritual power gradually turned from a disadvantage to an advantage, and he continued to gain the upper hand.

At the same time, around Lu Yan, Lu Wushuang and the others stared at Lu Yan intently, with a deep worry in their expressions.

"Come on, Lu Yan, you will definitely do it!"

Lu Tianqi clenched his fists tightly and said secretly in his heart.

Qin Ruoxi's beautiful eyes were staring at Lu Yan tightly, and the tension in her heart at this time was not weaker than that of others. Unconsciously, Lu Yan's position in her heart became important, and even she didn't notice it.

Nearly two hours had passed, and Lu Yan's refining of the Heart of the World was still in progress. His clothes were soaked with sweat, and his face was covered with beads of sweat. But Lu Yan was still as close as a rock, his eyes closed and motionless.

"Po"

At this moment, a crisp voice suddenly sounded in Lu Yan's ears, and Lu Yan was immediately ecstatic. This voice sounded, which meant that his spiritual power had completely dominated at this time.

With this crisp sound, Lu Yan felt that a picture suddenly appeared in his mind, and this picture was still expanding.

The first thing Lu Yan saw was Lu Wushuang and the others beside him, their every move, and even the change in their expressions could be seen clearly, and then the picture expanded, and all the passage buildings in the entire cave, the entire mountain range, the countless tombs in the entire area, countless treasures, and all the demon beasts were all clearly presented in his mind.

"Is this the whole picture of the entire Emperor Killing Secret Realm?"

Lu Yan said secretly in his heart.
