The rest of the conversation was only audible to Black Dragon and Elena.

"Little girl, I'll show you how to use your essence and blood!, find your own senses!" the black dragon said solemnly.

"Hmm......" Elena nodded obediently.

The black dragon injected his own power into Elena's body, using his own power to guide Elena in how to use her essence blood.

In the process of guidance, the black dragon advised: "Relax yourself, don't resist my strength!

Elena nodded again and said, "Mmmmmmmmmmmmmm

Xiao Nan looked at Elena and Heilong with his eyes closed boredly in his own mind, he didn't know what he was doing!

At this time, Xiao Nan always felt that he was completely superfluous!

A few minutes later, Elena and Black Dragon both opened their eyes, and at this time, there was a sudden realization on her face!

Xiao Nan knew what was going on when he saw this expression, which meant that the black dragon had successfully guided Elena through the first stage of blood refining.

At this time, a smile appeared on Elena's face, and she raised her head to look at the black dragon with great gratitude.

Elena bent down and bowed, "Thank you! Thank you for helping me!".

The black dragon immediately raised his hand and said, "No need! If you want to thank this kid, I won't help you if he doesn't beg me!"

After listening to the black dragon's words, Elena raised her head and glanced at Xiao Nan, and at this time, her eyes at Xiao Nan seemed to have changed from before.

Elena's eyes did not have as much sharp murderous aura as before, but more gratitude.

The black dragon shook the dragon's head, raised the dragon's claws and waved it gently.

"Now that the matter is settled, let's get out of here, I don't like people bothering me here!".

Xiao Nan nodded at the black dragon, and when he nodded, he also winked at the black dragon, which looked at the black dragon for a while, making it seem that one person and one dragon were full of affection.

After the two returned to the display, Xiao Nan let go of the hand that was placed on top of Elena's head.

At this time, Elena couldn't wait to start the first stage of blood refining!

Elena immediately showed a smile on her face as soon as she felt the change in power!

"I've succeeded!I've really broken through to the first stage of blood refining!."

"Hehehe......".

Xiao Nan on the side didn't speak.

Elena put away the breath on her body, and she raised her head to look at Xiao Nan gratefully again.

"Thank you, I didn't expect you to really be willing to help me, I may have blamed you before......" Elena looked grateful with a slight apology.

"Hahaha, I'm not a person who holds grudges!

On revenge, once Xiao Nan holds a grudge, the person who holds a grudge will be doomed!

At this time, Xiao Nan's image has changed dramatically in Elena's heart, at least in her heart, Xiao Nan is no longer the so-called scumbag.

Especially Elena's impression of Xiao Nan after listening to Heilong's words, Heilong said that the reason why he was willing to help her was because of Xiao Nan's help.

Xiao Nan went to ask for help from the black dragon for himself, which Elena never imagined.

What is the extreme, the opposite must be opposed.

Elena hated Xiao Nan to the extreme at first, and her more and more hatred of Xiao Nan in the following days led to a change in her thinking.

Now that I know Xiao Nan a little, I only find that Xiao Nan is quite good.

After successfully breaking through the first stage of blood refining, Elena couldn't calm down in her excitement for a long time, and the old man was silently observing everything in the darkness of the blood pool.

The old man seems to have deliberately hid to let Xiao Nan help Elena break through.

"The day of vampire blood unification is not as good as a day, and learning blood refining actually requires the help of humans. The old man touched his beard and sighed.

I don't know if this thing is good or bad, the vampire family used to be a legend, what caused their abilities to decline so badly?!

After a few minutes, Elena took a deep breath.

Xiao Nan glanced around the pool of blood and said, "Let's sit quietly! Don't let that old man find us ......moving around."

Elena nodded and sat down on the spot, Xiao Nan shook her head and meditated on the spot.

At this time, the old man slowly walked out of the blood pool, looked at the two people who were sitting quietly and nodded with satisfaction.

Now the affairs of the vampire family have long had nothing to do with the old man himself, and the family ruthlessly imprisoned him here back then, and he had already severed his relationship with the family.

The old man now only wants to pass on his life's work to others, and he will not live in vain and leave nothing behind.

Although Xiao Nan is a human being, this human being is different in the eyes of the old man.

......

Many days passed.

Xiao Nan and Elena followed the old man out of the cave, and the three of them came to an open area in the canyon.

The old man turned his back and smiled: "You are all in the first stage of blood refining now, but you have just broken through, and the first thing to do is to consolidate ......."

After a tirade, the old man asked Elena and Xiao Nan to start the first stage of blood refining at the same time.

Suddenly, the aura around them changed greatly, and Elena and Xiao Nan looked at each other.

The old man touched his beard and smiled, "The best way to consolidate is to fight! You two happen to be in the first stage!

Xiao Nanke Elena nodded to each other, it was also the first stage, and I didn't know who would be better.

Elena raised the corners of her mouth and smiled: "Don't cheat! You can only use blood to refine!".

Xiao Nan nodded confidently and said, "Don't worry! I don't need to cheat when I beat you! Say it again! Mine is not blood refining! It's extreme refining!".

Extreme refining was created by Xiao Nan based on blood refining! The way they move is different! So Xiao Nan doesn't want Elena to get confused!

This time, Xiao Nan also wanted to see what was the difference between his extreme refining and blood refining!

The old man nodded with satisfaction when he saw the fighting spirit of the two, and in an instant, the old man left the distance of hundreds of meters between the two! This is to not interfere with the normal exchange between the two.

The moment the old man left, Xiao Nan beckoned to Elena, and she did it first!

Elena was also unceremoniously pulled out her legs and rushed to Xiao Nan!

Whew——!

With the help of blood refining, Elena's speed is very fast!

For the sake of fairness, Xiao Nan didn't open the realm to restrict Elena! The two collided in a second!

The surrounding blood mist was instantly blown away by the air flow that the two of them collided with! The old man in the distance calmly watched the two fight.

Xiao Nan and Elena grabbed each other's palms together! The corners of Xiao Nan's mouth rose slightly!

"It's fast!I don't know how strong you are?!" Xiao Nan said with a smile.

"Cut! See if you can get me out!"

"Really?!".

Since Elena has said so, then Xiao Nan will definitely not be polite!

Xiao Nan's palm pinched Elena tightly! Elena immediately felt as if her palm had been squeezed by a vice!

"Ah!!h

"Drink ——!".

Xiao Nan burst into a shout! Spin on the spot! Elena directly took off with her feet like a big windmill!

This is Elena's shortcoming! As a woman, her weight is her hard injury! Xiao Nan easily threw it up!

After dozens of consecutive turns in the air, Xiao Nan's palms instantly released!

Elena was thrown out like a stone! Fortunately, she was in a strong posture so she didn't fall into embarrassment! Elena looked at Xiao Nan unconvinced after landing steadily.

Xiao Nan smiled, his own extreme refining used the power of the black dragon!

There is no need for Xiao Nan to explain too much about how powerful the power of the black dragon is, it is basically a good thing for Elena to win or lose with herself!

It's just that Xiao Nan wanted to ask for the same certificate, and sure enough, the result was the same as he guessed.

After the two fought, they both knew the gap between themselves and the other party, and Elena took the initiative to stop and end the fight.

Elena conceded defeat and said: "I am not your opponent in the first place, and this blood refining has just broken through, so I am not used to it......"

At this time, the old man appeared between the two unconsciously.

The old man touched his beard and smiled, "Very good! Linna, your promotion is very good! But if you say that you are not familiar, then you have to fight more!".

Elena thought for a moment and nodded, the old man was right.

Xiao Nan didn't care, just give up, let himself be Elena's sparring partner, and accompany him to the end.

The old man saw Xiao Nan's hand and smiled: "Don't get me wrong! I'm not letting you two fight! I want you to go to a place ......."

Xiao Nan frowned and asked, "What place?!"

This old man didn't know what to think in his heart, no matter what that place was, there must be more than one good place!

"The canyon goes all the way to the west! There is the lair of the Blood Sacrifice Beast! That is a good place to practice!"

Elena was dumbfounded when she heard this, this old man meant to let them go to the lair of the blood sacrifice beast to practice their hands?!

You must know that there are not only blood sacrifice beasts here, but also some outrageous wolf-like monsters with fast speeds, these things will kill them if they are not careful!

Before Elena could ask questions, Xiao Nan preemptively agreed to the old man.

"Hmph! It's really a good place to practice! Let me take revenge!" Xiao Nan grinded his fists and feet excitedly.

I haven't had fun fighting those wolf-shaped monsters and blood sacrifice beasts last time!

Elena glanced at Xiao Nan helplessly, this kid is probably crazy.

Xiao Nan immediately aimed at Elena's eyes, if she didn't want to go, she wouldn't force it, and it was no problem to be alone!

"What's the matter, if you're afraid, you can not go!" Xiao Nan smiled defiantly.

"Hmph, don't dare?!Go, go!Who's afraid of whom!" Not to be outdone, Elena put her hands on her chest.

......

More than half an hour later, Xiao Nan and Elena both came to the place that the old man said.

After walking to the west for a while, the two of them came to the end after more than half an hour, but the scene in front of them made the two a little staggered.

I thought there would be a bunch of monsters like blood sacrifice beasts living here, but after coming here, there was nothing to do!

Elena wondered, "Strange, isn't this the lair of the Blood Sacrifice Beasts?, why don't there be any Blood Sacrifice Beasts?!".

Xiao Nan was also puzzled, the more he thought about it, the more weird he felt, shouldn't it! Could it be that the old man with Alzheimer's memory was wrong?!

After walking for more than half an hour, Xiao Nan didn't want to come in vain, no matter how much he had to go back with the head of a blood sacrifice beast today!

Xiao Nan sat down on the spot, and Elena also knew that she sat down on the spot when she saw this.
