A few seconds later, the wall slowly opened a one person high hole.

There was a slow sound of footsteps.

Then, an old man appeared in front of the slanting light. The old man was naked, with skin folds like dead wood. He was wearing a pair of grey brown sports pants and a pair of white shoes at his feet.

However, Xu Fan and Lin Xiaoxiao in the distance are stunned by the appearance of the old man. As for Bai Yu, he doesn't know what's going on. He just looks around and is a little vigilant. Now he is looking at Xu Fan.

Xu Fan thought that he would be known as a great devil. He had to be fierce and black faced. Who ever thought he was such an old man who looked at the old and had no strength. However, Xu Fan didn't show any contempt.

But the old man is hale and hearty. Although his deep sunken eyes are a pair of blank eyes, just at the moment when he looks at Xu Fan, the deep part of his eyes suddenly burst out a burst of terrible light.

Xu Fan was still standing there, without the slightest intention of getting up to greet him. His face was a little strange, or heavy.

Looking at the old man, Xu fan can imagine what kind of pain or devastation the old man suffered when he was treated with experimental drugs. Maybe he was a middle-aged man or even a young man before that.

"If you still have consciousness, turn around and leave. If I don't kill you, you won't live long." Xu Fan suddenly opened his mouth and said nothing.

There was no change in the old man's face.

But Liu Yuanchang's look changed dramatically.

"Granddad, he?" Liu Yuanchang pointed to Xu Fan, surprised.

And Liu Yuanchang's grandfather is also a face of disbelief: "impossible, this time to understand" Lian Jing "is only our Liu family." While talking, the old man stares at Xu Fan, as if trying to find some flaw in Xu Fan's look.

"The great devil killed him for me." After observing for a long time, Liu Yuanchang's grandfather still yelled at the old man.

When the great demon heard this sentence, he suddenly raised his head and looked at Xu Fan. A fierce force burst out from him, like a bloodthirsty beast staring at his prey. When he had a chance, he would burst out with a fatal blow.

At the same time, his left hand threw out a short knife from his waist. The knife rushed to Xu Fan, but Xu Fan didn't panic at all. He took a step. The knife stabbed into the air, but through the ejection of the opposite metal wall, he flew into the air again.

The demon king's left hand flashed out and Shua held the knife firmly in his hand. He looked at Xu Fan with straight eyes and looked like an eagle preying on prey.

"I'll give you one last chance. I know you have a trace of consciousness. What's bound you, but if you choose to be my enemy, you really don't have a trace of survival." Looking at the old man, Xu Fan seemed to be a little serious, and the words seemed to be really painstakingly admonishing.

However, the old man obviously answered Xu Fan with practical action. His figure swayed, and the great devil shot out like a ghost. The knife in his hand rushed away with cold light, leaving a series of shadows in the air, piercing Xu Fan's heart.

Xu Fan curled his lips, disdaining to sneer: "the opportunity has been given to you, but you can use the power gained in this way."

Xu Fan almost leisurely if the body side of the step away from the big devil's attack.

But the dagger in the hand of the great devil suddenly turned, picked it up with his backhand, and instantly rowed to Xu Fan's abdomen. The dagger was as fast as a shadow, fast and unstoppable. Xu Fan's heart is tight, and he sighs that the old man's speed is really extremely fast. However, Xu Fan's figure is twisted to avoid the tricky knife.

This friction soon separated them from each other again.

However, Liu Yuanchang and his grandfather's eyes are full of panic. The great demon is the highest force they can take out. Now it's a draw with Xu Fan. If the great demon loses, Liu Yuanchang can't imagine that Xu Fan will let him go in the wilderness.

Thinking of this, Liu Yuanchang can't help but tremble. He looks up at his grandfather, reaches aside and holds a remote control in his pocket.

Then the two men fought again, and Xu Fan escaped the attack of the great demon king, but he was not hit. The sword style of the great demon king suddenly changed. The original short knife from the bottom to the top swept Xu Fan's neck in an instant. The sharp wind of the sword blew Xu Fan's sweat, and the danger was all around him.

"Sure enough, it's the product of refining." Xu Fan sighed in his heart about the power of the great demon while fighting with the great demon. Now Xu fan is a master of the earth level. He thought he could sweep the world. Unexpectedly, the great demon can fight with Xu Fan.

But Xu Fan's look is not the slightest panic or worry, because Xu Fan's many cards, now the same have not been used.

And there Xu Fan and big devil fight for a regiment, here Bai Yu also untied the rope for Lin Xiaoxiao.

"Do you know him?" Lin Xiaoxiao looks at Bai Yu with a puzzled face. He didn't expect that Xu Fan would meet acquaintances here.

"Well." But at the moment, Bai Yu is engrossed in looking at Xu Fan's worried look. He just nods to Lin Xiaoxiao's words.

Lin Xiaoxiao looks at Bai Yu's eyebrows and can't help but be stunned. He shakes his head and clearly understands that he is a woman who is infatuated with Xu Fan.

"What's the matter with the devil today? Haven't you had enough?"

On the second floor, the staff felt incredible that Xu Fan had not been hurt for such a long time.

But only the middle-aged man's eyes were fixed on Xu Fan, his expression was a little stiff, but the light in his eyes could not be covered up: "this is the perfect carrier." But he murmured.

With this saying, the middle-aged man suddenly turned around, opened a door from the wall, and then came back to the office of Liu Yuanchang and his grandson.

"I suggest taking back the great demon immediately." The middle-aged man looked at Mr. Liu Yuanchang and said this.

"That's why." That Liu Yuan Chang hears this person's words, not from of a Leng.

"This Xu fan is the strongest carrier I have seen so far. If we use him as an experimental object, I believe we can create a more powerful tool to kill people than the great demon king. As for the current situation in the capital, we Liu family can easily suppress the other three families." It seems that the middle-aged people have seen the perfect result of their imagination, and the smile at the corner of their mouth is getting stronger and stronger.

"I don't know Hearing the middle-aged man's suggestion, Liu Yuanchang's grandfather also took a breath and pondered for a moment: "you're right, but Xu Fan seems to be hard to control. The great devil can't defeat. How can we control it?"

Liu Yuanchang's grandfather looked at the middle-aged man and said the problem.

"It's easy." However, the middle-aged man didn't seem to care about this problem, with a confident smile on his face.

"Oh? What shall we do? " Looking at the look of the middle-aged man, Liu Yuanchang's grandfather became more curious.

"Well, look there." The middle-aged man turned his head and pointed to Bai Yu and Lin Xiaoxiao: "Xu fan can't control them. You can control them."

"Here it is." When Liu Yuanchang's grandfather heard this, his eyes narrowed. After a long time, they looked at each other and laughed.

"Do it."

"Yes."

After that, the middle-aged man turned and left.

However, the big devil is still around Xu Fan. It seems that he has not known the tired fighting all the time. Xu fan is also entangled by the big devil, and his heart is a bit restless. However, Xu Fan still wants to get familiar with his strength after breaking through, and then uses the enhanced second to kill the big devil. The main reason is that Xu fan can't wait to kill Liu Yuanchang.

But when Bai Yu and Lin Xiaoxiao are absorbed in watching Xu Fan's fight with the demon king, they suddenly feel a stabbing pain in their arms. They turn to see that a needle just stabs Lin Xiaoxiao and Bai Yu's arm.

After that, they collapsed and were held by the middle-aged man and old sun behind them. They didn't make any noise, and Xu Fan didn't notice.

When Lin Xiaoxiao and Bai Yu are taken out of the hall, the middle-aged man suddenly presses the remote control in his hand, and the demon king stops attacking Xu Fan. He covers his head and rolls on the ground in pain, and his eyes stare at the middle-aged man on the second floor from time to time.

Then the great devil ran into a passage opened by the wall beside him.

For all this sudden, Xu fan is also some do not understand and surprised, do they give up, Xu Fan turned his head to look at Liu Yuanchang sun with a puzzled face.

But Liu Yuanchang pointed to the second floor and Xu Fan looked at it.

Xu Fan frowned and looked up. The middle-aged man on the second floor dropped a needle tube to Xu Fan, who took it in his hand. The liquid in the needle tube was colorless and tasteless.

"Inject it." At this time, the field broadcast sounded the voice of grandfather Liu Yuanchang.

Hearing this, Xu Fan was stunned and looked at Master Liu Yuanchang: "are you not sick? Do you say I'll get an injection? "

However, the smile of Mr. Liu Yuanchang after hearing Xu Fan's words made Xu Fan's heart tighten, and then he quickly looked back.

Sure enough, Lin Xiaoxiao and Bai Yu have disappeared.

"You don't have to change it. If you don't inject the liquid, or if you walk around one step, I'll cut off both of them one part." Then came the voice of grandfather Liu Yuanchang from the radio, with a strong sense of threat.

At the moment, Xu Fan finally felt that the situation was not good. With a frown, he looked down at the colorless and tasteless liquid in his hand. As soon as he pressed his finger, the liquid flowed out a little and stained Xu Fan's finger.

Xu Fan put his finger on the tip of his nose and smelled it. A moment later, a smile appeared at the corner of his mouth.
