As the aura continued to enter the body and was refined, Ye Feng's aura began to slowly climb upward, but the speed of the rise was not as fast as expected, and after half an hour, Ye Feng did not feel any traces of breaking through.

"Although there is abundant spiritual energy here, the speed at which it can be absorbed into the body is too slow, and now every time I improve my cultivation, the more spiritual energy I need to refine, and the time for cultivating here is limited, it seems that it is far from enough to rely on the spiritual energy here to improve my cultivation, the speed of this improvement is too slow, I still need to think of other ways." Ye Feng touched his chin with his hand and said softly.

However, while Ye Feng was pondering, Ye Feng discovered a strange scene.

"What's going on?" Ye Feng said in surprise, he found that his Na Ring was absorbing the aura in this secret room.

Ye Feng immediately checked the situation of the ring, and found that it was the ancient sword Qinghong who absorbed the aura, Ye Feng took out the Qinghong sword from the ring and put it on his hand to check.

Without the obstacle of the ring, the speed at which the Qinghong Sword absorbed the aura was constantly rising, and it was slowly surrounded by the aura on the entire sword body, and a large amount of aura was frantically sucked into the Qinghong Sword, and even the aura in other places was attracted by the Qinghong Sword.

Looking at this extremely strange scene, Ye Feng was full of surprise, it was the first time he had encountered such a situation, he tried to inject the Qinghong Sword with soul power, but the Qinghong Sword did not react, just frantically inhaled the aura, Ye Feng also tried to spy on the Qinghong Sword with the magic eye, but still found nothing.

Half an hour later, the door of the secret room opened automatically, and the time for the use of the secret room was up, but Qinghong Sword was still frantically absorbing aura, but at this moment there were very few auras that Qinghong Sword could absorb, in order to avoid being discovered, Ye Feng quickly included Qinghong in the acceptance ring, which made Qinghong Sword stop the inhalation of aura, Ye Feng walked out of the door with a little nervousness, and then walked out of the underground palace.

After leaving the underground palace and returning to the Gathering Spirit Pavilion, Ye Feng heard a lot of people talking about it, all of them saying that the aura in the secret room suddenly became extremely thin, and even more said that suddenly he couldn't feel the aura in the secret room at all, and every disciple looked at the Gathering Spirit Pavilion with a puzzled expression.

Hearing these remarks, Ye Feng couldn't help but rub his eyebrows.

Ye Feng knew the reason for these strange phenomena, and he also had to admire the strength of this Qinghong Sword's ability to absorb aura, and he was able to attract the aura of the entire underground palace to himself.

Ye Feng walked to the counter a little embarrassed, at this time, Elder Huang was communicating with several other elders, Elder Huang and these elders were the people in charge of maintaining this underground palace, and now that this situation appeared in the underground palace, several people were all looking questions and worries.

"Elder Huang?" Ye Feng stepped forward to interrupt their discussion.

"What's the matter?I'm very busy right now, I don't have time to take care of other chores?" Elder Huang looked impatient at Ye Feng interrupting their discussion.

"I'm here to hand over my keycard. Ye Feng said, he was not displeased because of Elder Huang's bad attitude, but he was a little embarrassed because of his own reasons that caused them so much trouble.

"Just put the key card down. Elder Huang said.

"Okay, Elder, you're busy first. Ye Feng put down the room card, and then walked out of the Gathering Spirit Pavilion quickly.

"Senior Brother Ye Feng. As soon as Ye Feng walked out of the Gathering Spirit Pavilion, Bai Meng and Zhan Yun immediately walked towards him.

"Senior brother and sister, why did you come out so quickly?" Ye Feng asked with a smile a little embarrassed, although he knew the reason, it was necessary to pretend to be stupid now.

"The aura in the secret room suddenly became extremely thin, and it was useless to stay in the secret room, so I came out early. Zhan Yun said helplessly.

"Then do you know what's going on?" Ye Feng asked tentatively towards the two of them.

"I don't know yet, the elders are all checking it, and now it is estimated that this Gathering Spirit Pavilion will be closed for a while. Zhanyun sighed.

"Close, why is this?" This surprised Ye Feng, he didn't expect it to cause such a big impact.

"The aura in this Gathering Spirit Pavilion is accumulated over the years, otherwise it will not control the time for us to enter the secret room to cultivate, in order to keep the spiritual power inside abundant, and now the aura has suddenly disappeared, which will take a long time to re-accumulate, so it will be closed. Zhan Yun explained to Ye Feng.

"I see. Ye Feng pretended to understand whether he understood or not.

"It seems that this time the matter is a bit big. Ye Feng muttered in his heart, he didn't expect that the matter would be so serious, closing the Gathering Spirit Pavilion, it is estimated that it is the first time in so many years.

"Looks like I'm going to be able to go home. Bai Meng smiled.

"Senior Brother Zhan, do you want to go back with me?" Bai Meng asked as he looked at Zhan Yun.

Being asked by Bai Meng suddenly, Zhan Yun suddenly seemed a little unnatural, shy and didn't know what to say.

"You continue to work on this issue of going home, and I'll go first. Ye Feng said and left quickly, he didn't want to be a light bulb here.

Out of the cabinet, Ye Feng went to the task pavilion and counted all the tasks he had done before, but the number of task points he got was only more than a hundred, just because a few tasks had passed the deadline, and a few had not been completed.

After changing the task point, Ye Feng ran directly to Fairy Peak, the strangeness of the Qinghong Sword completely aroused his interest, and he wanted to go back and study this sword well.

On the Fairy Peak, Si Yao was not there, Lin Xuan was not there, and after Ye Feng returned to the Fairy Peak, he locked himself directly in the room.

Ye Feng took out the Qinghong Sword from the ring and put it on the table, the Qinghong Sword at this moment was the same as usual, there was nothing abnormal.

Ye Feng sat on the side and stared at the Qinghong Sword, looked at it for half an hour, but didn't see anything, Ye Feng tried to inject soul power into the Qinghong Sword again, but unfortunately the Qinghong Sword still didn't have any reaction

In desperation, Ye Feng had no choice but to give up, Ye Feng put the Qinghong Sword aside, and sat on the stool himself and fell into deep thought.

However, while Ye Feng was pondering, a voice appeared in his mind, "Little doll, where did the Phantom Demon Dragon Blood on your body come from?"

"Who is it?" Ye Feng woke up from his contemplation.

"I'm Phantasmagor. The voice replied.

"Phantom Demon Dragon?" Ye Feng was very surprised when he heard this name, he hurriedly looked around, but found nothing.

"You can't see me, I'm just communicating with you through the power of the soul right now. Phantom Demon Dragon said lightly.

"Soul power can also communicate?" Ye Feng was taken aback again.

"This is one of our dragon abilities, similar to your human voice. The Phantom Demon Dragon explained to Ye Feng.

"Didn't the Phantom Demon Dragon become extinct many years ago?" Ye Feng asked suspiciously.

"The Phantom Dragon is extinct, and I'm just a remnant now. The Phantom Dragon sighed.

"Remnant Soul, where are you now?" Ye Feng continued to ask.

"Right in front of you. "Phantom Demon Dragon Dao.

"In front of me?" Ye Feng looked ahead, but there was nothing in front of him except the Qinghong Sword.

"Are you in the Qinghong Sword?" Ye Feng suddenly said in shock.

"Yes, I've been sealed here for tens of thousands of years. The Phantom Dragon said with a long sigh.

"Does that mean that the aura in the Spirit Gathering Pavilion was absorbed by you today?" Ye Feng looked at Qinghong Sword in surprise.

"It's not all me, I just sucked a large part of it, and some of it was sucked by the flower. Phantom Dragon said.

"Flowers?" Ye Feng didn't understand.

"You have the Spirit Wheel Demon Pupil, you didn't even see it?" This time it was the turn of the Phantom Demon Dragon to be surprised.

"How do you know that I have a soul demon pupil?" Ye Feng asked.

"You've used it a few times in front of my eyes, how can you not know? I just don't know how you are such a weak chicken, how can you have such a pupil that reaches the sky. Phantom Demon Dragon said to Ye Feng with a little disdain.

"You are so powerful, it's not that you've been sealed for tens of thousands of years, if I guess correctly, it's not because I took you into the Gathering Spirit Pavilion and absorbed so much spiritual energy to wake up, otherwise I don't know how long I will sleep until I sleep, and I still say that others are weak chickens. Ye Feng was a little displeased by the Phantom Demon Dragon.

"This is the Ancient Demon Slaying Sword, you think it's your scrap copper and rotten iron, I have been sealed for tens of thousands of years without being destroyed, which is enough to prove my strength. The Phantom Demon Dragon didn't have a good aura towards Ye Feng.

"This Qinghong Sword is an Ancient Demon Slaying Sword?Since it is so powerful, will it be particularly powerful in fighting?" Hearing that the Phantom Demon Dragon was so jealous of this Qinghong Sword, Ye Feng suddenly became interested.

"You can use it, you can't exert its power, it's a waste that such a good sword actually falls into the hands of a weak chicken like you. Phantom Dragon said.

"Not being able to do it now does not mean that it will not be able to do it in the future, and when I go up in cultivation, I will definitely be able to give full play to its due value. Ye Feng said confidently.

"Even if you reach the Heavenly Emperor Realm, you won't be able to use it, unless you can find a way to unlock this sword's ability. Phantom Demon Dragon said proudly.

"How to open it?Then you have lived for so long, do you know the way to open it?" Ye Feng asked the Phantom Demon Dragon with a smile.

"I don't have to be trapped here for tens of thousands of years if I know. The Phantom Dragon was speechless.

"When I didn't ask. ”

........

"You've asked me so many questions, and you haven't answered my questions yet, tell me quickly, where did your Phantom Demon Dragon's blood come from?"

"It was given to me by a senior, and I don't know where he got it from. Ye Feng replied truthfully, speaking of this, Ye Feng couldn't help but think of the Thousand Machines Dao people, as well as the promise he made to the Thousand Machines Dao people.

..........

"Little doll, how about we make a deal?" the Phantom Demon Dragon asked Ye Feng after being silent for a while.

"What deal?" Ye Feng was a little curious.

"Give me your Phantom Demon Dragon blood, and I'll help you recover your cultivation. Phantom Dragon said.

"Do you have a way to restore my cultivation?" Ye Feng said in surprise.

"Of course. The Phantom Dragon replied in the affirmative.

"Wait a minute, how do you know that my cultivation is complete?" Ye Feng had never mentioned the previous matter in front of others, why would the Phantom Demon Dragon know.

"What's so difficult about this, you can see it at a glance, you used to cultivate in the Wuzun realm, but you are still a weak chicken. The Phantom Dragon said disdainfully.

"Can you not be weak before and after the weak chicken, you chat like this, it's easy to get beaten. Ye Feng said with a dark face.

"Weak chicken, weak chicken, you are a weak chicken, your whole family is a weak chicken. The Phantom Dragon shouted happily.

"You shout again, and then shout at me to throw you into the pit?" Ye Feng's face was already black and shiny.

"I was just kidding you. The Phantom Demon Dragon screamed quickly.
