As soon as the light curtain formed, the strongest stone turtle slammed into it.

With such a strong impact, even a hundred-foot-high hill would be smashed in half by it, but although the light curtain was knocked upside down and flew out and embedded in the collapsed cave behind, it only shook slightly, and recovered in an instant.

If that's the only way to do it, it only means that this shield is more defensive than the original one.

However, at the same time as the stone turtle collided with it, a scream instantly spread.

At the same time, the stone turtle quickly retreated, and its head was completely retracted into the turtle shell. It took a long time for him to slowly stick his head out again.

At this time, Li Xiao found out. On his forehead, there was a burn mark from the place where he had just hit.

Seeing this scene, Li Xiao couldn't help but gasp.

The stone turtle itself is a fire-attribute demon beast, and his origin energy is also a melting attribute of flames, coupled with his own strong defense.

However, even so, he was still burned by that formation at the moment of touch. One can imagine how perverted this sacrificial fire array is.

Looking at the sacrificial fire formation that flew out of the new air, Li Xiao's face became serious.

He had seen this formation before, but this formation was too demanding, so he didn't deliberately look for the strange fire needed by the formation.

But I didn't expect it to be so powerful.

Just sighed for a while, Li Xiao attacked again.

However, this time he didn't use the spirit sword again, but put them all away.

Because this formation can not only burn the stone turtle, but also dissolve the spirit weapons and soul that attack him.

I saw Li Xiao's hands quickly pinching the trick, and then the two palms were placed opposite each other in front of his chest. Black and white arcs appeared on his hands.

The two colored arcs met between his palms, and finally formed a fist-sized circular ball of light between his palms.

The colors of the photosphere are constantly and rapidly intersecting between black and white, like a solar eclipse.

As soon as the ball of light formed, it immediately broke away from his palms and flew towards the protective shield on the opposite side. After the ball of light flew out, it quickly grew larger, and in the blink of an eye, it became the size of a zhang.

After the first one flew out, the arc in Li Xiao's hand did not disappear, but fused into a second ball of the same light again, and flew away immediately after the first ball of light.

Then came the third, the fourth, and the fifth.

When the first ball of light collided with the light curtain of the fire sacrifice array, there was only a trace of ripple on the light curtain and the ball of light was resisted.

On the contrary, the ball itself began to appear unstable and quickly turned red.

At this moment, the second ball of light collided directly with the first one and instantly merged into it.

After the two balls of light fused, they instantly became larger, and at the same time, the power became much greater.

The light curtain was hit by this, and it began to shake immediately.

Immediately after that, the third, fourth, and fifth balls of light merged into the previous orbs of light.

As the ball of light gets bigger and bigger, so does its power.

When the fifth ball of light was integrated into it, the entire ball of light had become ten zhang in size.

Although it does not have the power of the Origin, its power is enough to be compared to the all-out attack of an ordinary late-stage distracted monk using the power of the Source.

Under such a powerful impact, the light curtain began to deform, but there was still no sign of cracking.

At this time, the attack of the other three stone turtles also arrived. Three fiery red magma pillars slammed into the light curtain.

However, the stone turtle's attack itself was a fire attribute, which did not do much damage to this sacrificial fire array, but instead replenished its energy. It has become more solid.

Seeing this, the three flintstone turtles quickly stopped. Then he turned and attacked the area around the collapsed cavern behind them.

Seeing this, Zhu Batian frowned. He wanted to intercept it, but the ball of light in front of him made it impossible for him to get out for a while.

The area around the cave was broken, and the entrance to the cave was revealed again. Zhu Batian and the three of them glanced at each other, and then as if they had made up their minds, they gritted their teeth and quickly pinched their hands.

As they moved, the surrounding magma began to surge wildly, and quickly gathered towards the Sacrificial Fire Array.

All the magma that was close to the fire sacrifice array, the power of the flames in it was quickly absorbed by the light curtain, and finally turned into volcanic rock and fell.

Feeling the rapidly dropping temperature around him, Li Xiao frowned. Immediately guessed the other party's plan.

This also confirmed his other suspicion.

The other party did not dare to let the stone turtle enter the magical cave, there should be something in it that could make the stone turtle enough to defeat their existence.

As for what this thing is, Li Xiao can't guess. But it's certainly not a panacea.

However, this has nothing to do with Li Xiao. All he needed to do was drag the three of them so that the stone turtle could enter the cave.
