The Strongest Upgrade System

Long Fei was very upset by Mu Nanyou's attitude.

Whenever he wants to accept an apprentice, he has to use all his efforts and means to prove himself. If he was in the ancient world, if he climbed up and shouted, I am afraid that countless people would squeeze in without breaking their heads.

But what about now?

It became a joke completely, and the other party didn't show any tolerance at all, even if he was under pressure, it didn't work.

They don't even believe in their existence at all.

At this time, the black dragon was instantly panicked.

He felt that he was going to be linked again, even to the point of being shot.

Long Fei wants to do it now, and he is the only one who can prove his means.

In the previous sentence, depriving him of his bloodline would deprive him of his power, making him a waste without any power.

Now, Mu Nanyou still doesn't believe it. If Long Fei tries to prove himself again, what will he use to prove it?

Just kill him!

With this thought, his heart was shrouded in infinite fear.

"My life is over!" he moaned.

But under the pressure of life and death, he also mustered the courage to explode.

"Mu Nanyou, did this king owe you a debt before, since I became your spirit, I have always tried to improve myself and you. I know you are a devil, but I didn't expect you to be so unsympathetic. You must kill me, are you willing?" Hei Long roared.

This has exhausted his energy.

Mu Nanyou was taken aback.

"Heavenly Devil dragon, I never wanted to harm you, how could you say that?" Mu Nanyou frowned.

"It didn't hurt me? It didn't hurt me, you don't believe it? You were convinced by my ancestors, but you still questioned that the ancestors have already deprived me of my blood, and you let the ancestors show up, you want to let the ancestors Are you satisfied with my life?"

Heilong felt infinite sadness in his heart.

I feel like I was killed by Mu Nanyou.

If Mu Nan took a step back now and went directly to the teacher, he would not suffer so many hardships.

Long Fei was stunned for a moment, looking at the roaring mad black dragon, with a mixture of laughter and laughter in his heart.

Suddenly, Long Fei felt a little cruel.

But at this time, Mu Nanyou was silent.

"I worship you as my teacher!" she said suddenly.

Obviously, she was also told by Heilong's words, knowing that if he continued, Heilong might have an accident.

Long Fei chuckled lightly.

I didn't expect it at all, and it was done like this?

If I had known this earlier, it would have taken so much effort.

"Very good. Although you don't deserve to be a dragon, but for the sake of your knowledge of current affairs, I will give you a chance today to make you a real dragon." Long Fei looked at Heilong and said lightly.

If it weren't for the sudden outbreak of Heilong, it would have taken a lot of effort to get this Mu Nanyou down.

"What? The ancestors want to give me a chance?" Heilong was dying, but when he heard Long Fei's words, he instantly returned to light, his anger disappeared, and he became extremely excited.

"Of course, this seat always speaks the truth." Long Fei said.

While speaking, a drop of blood suddenly appeared in the void.

This is naturally Long Fei's blood.

But now Long Fei's physical strength has not recovered, so the power of this drop of Blood Essence is naturally only the power of Ancestral Dragon.

Of course, Long Fei is just unable to appear in this world with a physical body, which does not prove that he has no physical body. So being able to squeeze out the menstrual blood is also at your fingertips.

"Huhu..." Heilong breathed heavily in an instant, staring at the Blood Essence in front of him.

As soon as this blood appeared, he felt the monstrous ferocity from it.

That feeling, even when he was at his peak, had never appeared in the face of the oldest existence of this dragon race.

"This is the Blood Essence of the dragon race. No, this is the real dragon race. Compared with this kind of power, the Heavenly Devil dragon is garbage."

At this moment, he was even more determined, Long Fei was definitely the existence of his ancestors.

"Swallow it down, and then you will be reborn from blood." Long Fei said.

Compared with the power system in this world, Long Fei is naturally extremely confident in his own power. He believes that this drop of Blood Essence will definitely make the black dragon transform, directly return to the ancestors, and even surpass the original level of life, and truly become a giant dragon.

"Ah, my ancestor, I have decided. From today onwards, you are my ancestor. If anyone dares to disrespect you, I will be his ancestor." Heilong quickly expressed his sincerity.

On the other hand, Mu Nanyou's eyes showed a hint of coldness.

Once upon a time, this black dragon was extremely arrogant in front of her, and it was always a gesture of absolute indifference towards her.

But now, it shows such a humble picture.

"Don't go around relatives, this is just a reward for you to be more obedient." Long Fei said.

Joke, he came to this world to stir up trouble.

Not to be a backer for others.

It was this black dragon, but it was only because the other party helped him to restrain Mu Nanyou that he gave him such a reward.

To put it bluntly, this is a tool man.

If it can't bring convenience to Long Fei, Long Fei waved his hand to obliterate it.

Heilong's expression froze and panic appeared.

But he didn't dare to say anything more, he didn't dare to disobey Long Fei at all.

At this time, the Blood Essence finally fell,

Heilong couldn't wait, opened his mouth and swallowed it.

But the moment he swallowed Blood Essence, the entire void suddenly trembled.

The next moment, the thunder is rolling, and the clouds are thick.

The blood-colored lightning fell directly from above the void, each with the thickness of a bucket, and it felt terrifying just at a glance.

What is even more terrifying is that the entire sky is also suddenly dark, as if night is falling.

"How could this be?" Mu Nanyou frowned, as if she couldn't believe it.

She exclaimed, her face changed sharply, especially at the end, as if she thought of something extremely terrifying.

"Heavenly Tribulation? This is Heavenly Tribulation? How is this possible, no one in this world has been able to welcome Heavenly Tribulation for so many years, how is it possible!"

Her face was full of horror.

If she hadn't seen it with her own eyes, she wouldn't believe it at all.

What made it even more difficult for her to accept was that all the changes in front of her were caused by the black dragon.

As for the rest, needless to say, she naturally knows that the black dragon can have such a good fortune only by a drop of Blood Essence from Long Fei.

A drop of Blood Essence can cause such power?

She couldn't imagine how strong Long Fei would be if he came.

This has completely broken her cognition and her cognition of the world.

At the same time, it also made her truly understand that Long Fei is a real master, and he is the kind of existence that is extremely powerful.

Suddenly, something moved in her heart.

If she had doubts about Long Fei before, now, she already knew how ridiculous her previous doubts were.

However, before she could speak, she was interrupted by a roar.

Because, the black dragon in front of me is the real beginning...the road of transformation.

"Roar!"

With a roar, the black dragon's figure was directly hit by the thunder.

Immediately, he, who was already weak, was directly exposed to the flesh...
