"How to increase energy?" Luo Tiange asked.

"The higher the host's realm, the stronger the energy of this system." The system replied.

"Didn't I just upgrade? You can refine the undead phoenix, why can't you refine it?" Luo Tiange asked.

"The current level of the host is not enough. I was able to refine the undead phoenix before, because it was just a remnant of the soul that has been wiped out for many years. Moreover, I want to swallow your soul. This system is not easy to refine."

Hearing the system's explanation, Luo Tiange nodded slightly.

"Brother, let's go back." Luo Tiange's face showed a look of embarrassment.

Only when the strength is strong, and then refining Zhu Yan.

Now, it is better to find a weak beast to refine.

"…"

The old madman looked at Luo Tiange, frowned and thought, "Are you trying to refine Zhu Yan?"

"Yep."

Luo Tiange nodded helplessly.

"Okay, then I'll help you, but you promise me one thing," said the old lunatic.

"what?"

Luo Tiange looked startled, his face full of disbelief, "Brother, say it."

"I want to eat Zhu Yan's meat, leave it to me." The old lunatic said.

"Big brother, Zhu Yan is a human-shaped beast, don't you feel bad about eating it?" Luo Tiange asked.

"That kind of fierce beast, the whole body is full of magic medicine, whether it is human or animal shape!" said the old lunatic.

"That's fine." Luo Tiange nodded.

The old madman looked at Zhu Yan, his pale face was full of caution.

Yan Chi jumped onto Luo Tiange's shoulders, lying there, not daring to move.

"Brother, I'm going to fight Zhu Yan first, you can take the opportunity to refine it," said the old lunatic.

"Okay." Luo Tiange nodded.

"call out…"

The old madman flickered and disappeared instantly.

"Roar…"

A roar shook the entire cave.

Zhu Yan opened his eyes, and two red lights shot out.

"Damn human, you are here again." Zhu Yan roared again and again.

"call out…"

It was like a surging wave of air, and it roared rapidly.

The sand on the ground hit Luo Tiange like a bullet.

"Ding…"

Luo Tiange's body is extremely strong, and these sandstones did not cause any damage except for the metal fire.

"Dang..."

Zhu Yan struggled to stand up, and the two huge thick iron chains behind him pierced through its pipa bones and collided.

Baizhang's body is like a giant mountain lying there.

"howl…"

Zhu Yan slapped his chest and let out bursts of whistling.

The monstrous force spreads in all directions like a tsunami.

Even if he was far enough away, Luo Tiange's heart trembled.

Yan Chi, who was lying on top of him, shivered even more.

"Stupid human race, dare to provoke this seat, take your life!"

A giant hand, piercing the sky, aimed at the old lunatic and slapped it down.

"Ha ha…"

The old lunatic smiled coldly, stretched out his right hand, and put it on top of his head.

"boom…"

There was a loud noise, and the earth was about to crack open, shaking rapidly.

Countless runes lit up, emitting a soft glow, offsetting all this power.

The old madman stood on the spot, sturdy and powerful, like a god, and he didn't move at all.

"Zhu Yan, what are you doing?"

The corner of the old madman's mouth raised, and the rune on his palm lit up, bursting with dazzling light.

With a palm, it landed on Zhu Yan.

"boom…"

Zhu Yan's body flew upside down and fell heavily to the ground, disgraced.

"Damn, **** it!"

The sound of rage came from Zhu Yan's mouth.

He struggled hard, and countless runes lit up all over his body, as if to crack the chain.

"call…"

Above the chain, there are also runes surging, dissolving all the power on it.

"boom!"

At this moment, the old madman slammed in, making Zhu Yan dizzy.

"howl…"

Zhu Yan struggled and roared again and again.

It surging with runes in both hands, kept pounding to the ground.

"boom…"

The earth shook and the mountains shook, and the boundless air waves shook in all directions.

The old lunatic walked under Zhu Yan's fist, as light as a swallow.

No matter how many punches it throws, it can't hit the old lunatic.

"Little bug, you completely angered this seat."

Zhu Yan roared again and again, and his breath quickly soared.

The monstrous ferocity is rolling in.

The old lunatic seemed to be stuck in a quagmire, and his speed was 90% slower.

"Ant, go to hell!"

Zhu Yan stretched out his big hand to cover the sky and slapped it straight down from mid-air, as if he wanted the old madman to slap it into flesh.

Luo Tiange looked at this scene, sweating coldly.

Facing Zhu Yan, I was afraid that I would not be able to do it.

Every time Zhu Yan took a palm, there were at least hundreds of millions of gigantic forces, and when he slapped it on himself, I was afraid that his soul would be shaken away.

"Run!"

Seeing that the old lunatic didn't move, Luo Tiange yelled.

The old madman looked at Zhu Yan's palm with runes surging, and the corners of his mouth rose slightly, "Do you want to kill this old man just because of this?"

"Om..."

There was a shock.

The golden runes surging on the old madman's body, and the whole person's breath is also rapidly soaring.

"boom…"

The two palms collided, earth-shattering.

If it weren't for the protection of a large array, I'm afraid the entire Demon Suppression Prison would be moved to the ground.

"Boom..."

Zhu Yan's body flew upside down again, hitting the ground heavily, vomiting blood from the corner of his mouth.

Obviously, the injury was not minor.

It struggled to stand up, looked at the old lunatic, and put away the previous contempt.

"Om..."

On Zhu Yan's brows and bones, runes surged.

These runes were quickly stacked together to form a kilometer-high golden vermilion.

If it weren't for the suppression of the formation, I'm afraid that this golden Zhu Yan would not be a problem.

"Fa Xiangtiandi."

Seeing this scene, Luo Tiange's eyes lit up.

It seems that Zhu Yan resorted to the bottom of the box.

The law of heaven and earth is used, and the surrounding pressure is a hundred times stronger.

The old madman's face was solemn, his hands clenched, and his mouth was muttering.

"call…"

A long sword emerged from his brow.

All kinds of runes light up on the long sword, the rays of light are exhaled, and the divine power is rippling.

"Artifact!"

Seeing this long sword, Luo Tiange secretly exclaimed.

Artifacts are weapons bred by gods through physical sacrifice.

The power is unimaginable.

"Om..."

The old lunatic waved his long sword and slashed forward lightly.

Behind Zhu Yan, Fa Xiangtiandi stretched out his giant hand to cover the sky, aimed at the long sword, and slapped it down.

"Boom..."

Like a thunderbolt on the head.

A dazzling light illuminates the whole insight.

Shocking power, sweeping all directions.

Luo Tiange hurriedly closed his eyes, covered his ears, and at the same time, made a hurricane step and quickly retreated.

He found a protruding rock wall and quickly hid behind.

"Ding Ding..."

Pieces of gravel came quickly, nailed to the stone wall, and the whole was inlaid.

Luo Tiange's face changed slightly when he saw this scene.

Under the blocking of the formation, this aftermath is still so terrifying.

How terrible are the two of them?
