It was the moment the black fire entered the body.

A sharp, burned-out pain instantly hit Eucommia's brain.

Du Zhong immediately stretched out his hand from the old man, and sat down on the spot as soon as his footsteps moved.

In the body, energy surges wildly.

Trailing behind the black flames, constantly repairing the burned area.

At the same time, Du Zhong immediately controlled his spiritual power to extract most of the remaining Dragon Yang Fruit energy in his body to suppress the black fire.

During the time when Du Zhong mobilized the energy of Long Yang, Black Fire thought that he had escaped.

It is like using Eucommia's body as a playground.

Unscrupulous, crazy rampage.

After several turns in Eucommia's body, Black Fire turned around and directly targeted Eucommia's brain.

It's gone.

I'm afraid that Du Zhong's brain will be burned out in an instant.

"Whew......"

Black Fire didn't have any worries, and rushed forward with great arrogance.

"Humph!"

At this moment, Du Zhong secretly snorted coldly.

The dragon yang energy that was completely gathered, under the control of Du Zhong, rushed to Du Zhong's heart, blocking the path of the black fire.

As soon as the dragon yang energy appeared.

The incomparably presumptuous, arrogant black fire, instantly stopped.

"Buzz ......"

In the battle with Longyang energy, the black fire group, like a newborn wolf cub, saw the majestic lion, and was gradually frightened by the momentum of Longyang energy, trembling slightly.

The original fist-sized mass of energy was curled up little by little in the trembling.

Finally, it shrunk to the size of a thumb, extremely dark, and extremely hot.

It looks like a black hole.

"Melt!"

For this black fire, Du Zhong has no mercy.

Directly drive the dragon yang energy, surging upward, will envelop the black fire.

Wrapped in the energy of the dragon yang, the black fire ball that curled up to the size of a thumb trembled again, and the speed of trembling was very fast, and Du Zhong's body could hear the sound it made when it trembled.

In the trembling, the edges of the black flame began to blur and dissipate.

Little by little, it was assimilated and fused by the energy of Longyang.

Soon, it completely disappeared into Eucommia's body.

The energy of the dragon yang fruit has increased by a point.

But Du Zhong didn't notice that there was still a faint trace of the black fire left in the dantian......

"Hoo ......"

On the ground, Du Zhong breathed a sigh of relief and opened his eyes.

"How?"

At the moment when Du Zhong opened his eyes, the old man rushed over with an arrow, grabbed Du Zhong's arm, and frowned to check Du Zhong's body.

At this moment, there is no black fire to spare.

The old man's complexion changed a lot, and he stepped out of bed, looking many times more energetic than before.

"Huh?"

When he examined Du Zhong's body, the old man's face gradually smeared with a hint of shock.

"Little friend's energy ......"

Only then did the old man understand why Du Zhong was so confident in introducing black fire into his body.

It turned out to be because of the existence of this energy.

It's just that, how can there be such an energy in Eucommia's body?

The old man was puzzled.

"That's right."

Du Zhong grinned and briefly told the old man about how he had cold poison, looked for Longyang Fruit, and took Longyang Fruit.

After all, the old man is the predecessor of the old generation with Mu.

This kind of thing, explained clearly, maybe there will be some mention.

"It's not easy, it's not easy......"

Hearing Du Zhong's explanation, the old man was suddenly amazed, and while marveling at Du Zhong's good luck, he opened his mouth and said: "Good people have good rewards, and teachers and nephews are so kind-hearted, and it is natural to have this blessing." ”

Du Zhong smiled humbly and did not make a sound.

"The old man can feel that this energy in your body is very powerful, and at the same time it is very gentle, even if it can't be refined, it won't hurt you, but it can help you in some specific things."

Speaking of this, the old man smiled and said, "For example, just now. ”

Du Zhong nodded, indicating understanding.

"Once you completely refine this energy, the future will definitely be limitless!"

The old man opened his mouth.

"The seniors have won the prize."

After listening to the old man for a long time, Du Zhong hurriedly opened his mouth and replied.

The old man laughed.

looked at Du Zhong with a deep meaning, and said: "This time, I owe you a favor to both your master and apprentice, and I also owe you a life, what you want, as long as I can meet it, I will definitely promise you." ”

"This ......"

Du Zhong groaned, and then turned his head and looked at the three pieces of paper placed next to the head of the bamboo bed, one of which was a rubbing book under the dragon's head!

"You want these three pieces of paper?"

Seeing Du Zhong's gaze, the old man stared slightly and asked curiously.

"Yes!"

Du Zhong nodded.

"It seems that my nephew seems to know the origin of this paper?"

The old man's eyes rolled and asked tentatively.

"I don't know."

In the face of the old man's inquiry, Du Zhong did not hesitate at all, and directly shook his head and denied: "I have only seen this kind of writing in other places, and it is said that there is a big secret hidden in these words, so I am a little curious." ”

Hearing this, the old man nodded knowingly and said, "If I'm not mistaken, you saw it under the faucet, right?" ”

"Yes!"

Du Zhong nodded in acknowledgement.

"Haha......"

The old man laughed, and said while laughing: "Everyone knows that the words under the dragon's head hide a great secret, but in this world, no one can crack it at all, even if they know that there is a secret, what can they do?" ”

Du Zhong pretended to understand and nodded.

"Still, since you want it, I'll give it to you."

As he spoke, the old man stretched out his hand, grabbed the three pieces of paper directly, and handed them to Du Zhong.

Du Zhong reached out and took it.

"That's right."

When he handed the three pieces of paper to Du Zhong, the old man seemed to think of something, turned around and ran to the desk, opened the drawer, took out a few pages of paper from it, handed them to Du Zhong, and said: "These are also things that I have translated and researched myself, since you are interested, I will give them to you together." ”

"Thank you, senior!"

Du Zhong hurriedly stepped forward to take it and said with joy and gratitude.

When he received the paper, his eyes swept over the old man's drawer.

When he just looked back at the old man, his face suddenly changed, and he turned his head sharply again, staring at something in the drawer.

That's a black token.

There is another word on the token made of pure black iron.

Eye!

When he saw this token, Du Zhong instantly thought of his token with the word "body", and the two tokens, except for the difference in the words on them, were exactly the same in other places.

"Huh?"

The strangeness of Eucommia attracted the attention of the old man.

When he found that Du Zhong's gaze fell on the token, the old man frowned violently.

With a solemn face, he asked, "Have you ever seen this kind of token?" ”

Hearing this, Du Zhong immediately nodded.

"Huh!"

Just as Du Zhong nodded, the old man suddenly stretched out his hand, grabbed Du Zhong's shoulders violently, and asked urgently with a nervous expression, "Have you seen it there, what words are written on it?" ”

Du Zhong gritted his teeth slightly.

The old man's sudden attack made him a little painful.

Both shoulders, under the old man's grasp, couldn't even lift up.

He was extremely shocked in his heart, only then did he know the strength of the old man, and a simple grasp made him unable to move a bit!

Du Zhong's expression attracted the attention of the old man, and the old man immediately let go of his hands, took a deep breath, and while calming the excitement in his heart, he gestured to Du Zhong with his eyes, sorry.

"Senior, what do you have to do with this token, why are you so nervous when you mention this token?"

Du Zhong asked cautiously as he rubbed his shoulders.

"What's the relationship?"

The old man's face turned cold, and he opened his mouth and shouted: "Mortal enemy! ”

Du Zhong's face changed.

"It's not just me, your master and the person who holds these tokens also have a mortal enmity!"

The old man spoke again.

This time, Eucommia was completely surprised.

He didn't expect that this token would actually involve Mu Lao.

Mu Lao has a mortal enmity with someone?

How come I've never heard of it?

Moreover, with Mu Lao's strength, who would dare to have a mortal enmity with him?

Suspicious, Du Zhong spoke: "I have seen such a token before, but it is written with the word "body". ”

"Body?"

The old man raised his eyebrows sharply, and hurriedly opened his mouth to ask, "When you saw the token, did you find any strange people around the token, or the person who held him?" ”

"Yes."

Du Zhong nodded in reply.

"Where's the man?"

The old man immediately asked.

"Dead."

Du Zhong replied truthfully.

"Huh?"

The old man was stunned for a moment, looked at Du Zhong with a puzzled expression, and asked, "How did you die?" ”

"I killed it!"

Du Zhong opened his mouth.

"Huh?"

The old man's face was shocked, and then he suddenly became excited again, took Du Zhong's hand, walked to the table and sat down, and couldn't wait to open his mouth and say, "Come on, tell me in detail, how did you kill people." ”

Hearing this, Du Zhong nodded.

Then, in front of the old man, he completely told the story of the Mobei plague.

Originally, the old man was Xu Hongru's master, and he also lived in the mysterious army, so Du Zhong didn't care much, anyway, it wasn't a leak to tell the old man.

And the old man also listened more and more fascinating, and listened to it with relish.

"In the end, when there was really no way, I could only pretend to show weakness, and then find the right opportunity, fight with all my strength and punch him, directly shattering his dantian, and then killing him......"

At this point, Eucommia stopped.

"Good!"

As soon as Du Zhong's words fell, the old man stood up and said loudly, "Good kill!" ”

"Finally, another one died!"

As he spoke, the old man's face showed a gloomy color, as if he wished that those people would all die.

"Senior, is there any grudge here?"

Du Zhong asked.

"This ......"

When the old man was about to speak, he suddenly shook his head and said, "You better go back and ask your master, if your master doesn't say it, I don't dare to overstep my bounds." ”

Du Zhong was stunned.

"That old guy has always been thoughtful, and if he doesn't say it, there must be his reasons, and I can't spoil his plan."

The old man nodded as he spoke.

Hearing this, Du Zhong was directly speechless.

He couldn't figure out what kind of grievances made the two sides form a mortal enemy.

I can't understand why Mu Lao is hiding it from him and not suing him.

Could it be that this matter has anything to do with him?

Or is he not qualified to know with his strength?

"Take it."

Because of the token, Du Zhong had not yet finished the pages he had translated from the old man's hand, and at this moment the old man handed the paper to Du Zhong again, and said solemnly: "If you have the opportunity to find the secret inside, you must cultivate hard." ”

"The younger generation should work hard."

Du Zhong took the paper and nodded in reply.

Looking at Du Zhong, the old man nodded with satisfaction, and there was a faint hint of expectation in his eyes.

Slightly.

The old man exhaled lightly, opened his mouth slightly, and said softly, "Come in." ”

As soon as the words came out, they immediately reached the ears of Xu Hongru and the other three in the living room.

The three of them immediately ran in......
