Looking at this situation, it seems that what Xu Qingyun said is true.

This is naturally the best.

Lin Du and Qingniu both stepped back to make room for Xu Qingyun.

The Yin-Yang Valley in front of him looked like there was nothing, but it was actually blocked by a barrier.

Don't say it's the line of sight, even the divine consciousness can't pass through.

What kind of scene was inside, Lin Dui couldn't know.

Whether Xu Qingyun can break through this barrier, he is also uncertain in his heart.

Xu Qingyun didn't delay, and immediately sacrificed the nine-star refining furnace and frantically urged the spiritual power.

Nine stars flashed brightly.

The eyes of the shining people are almost unable to open, and the edge of the peerless spirit treasure is extremely sharp.

In the next moment, the Nine Star Refining Furnace was like a big mountain, smashing into the blank space in front of him.

Rumble.

Under the huge tremors, the air was shaken.

Ripples.

Lin Du and Qingniu were both surprised at this time.

"I see. ”

Yin Yang Valley, where nothing could be seen before, suddenly appeared a visible transparent barrier.

Under the attack of the Nine-Star Refining Furnace, the transparent barrier kept trembling, like water waves.

Soon, however, the ripples, which were dense at first, spread out rapidly, gradually thinning out, and then calming down.

It's like throwing a pebble into the middle of the sea, and finally returning to peace.

"So strong. Qingniu couldn't help but be surprised.

What kind of barrier is this, exactly.

Lin Du was also surprised.

The moment Xu Qingyun urged the Nine Star Refining Furnace just now, the powerful coercion made even him feel extremely terrifying.

But in the face of this transparent barrier, such an attack could not make any ripples.

Now things are in trouble.

If Xu Qingyun couldn't break through the barrier in front of him, his attack power would not be much stronger than Xu Qingyun.

Then they can only stop here abruptly.

Lin Du was very unwilling.

In order to save Xu Jiao, he did not hesitate to take out the Nine-Star Refining Furnace, taking a huge risk, and traveling for so long, the spirit stones spent on the teleportation array alone were a lot of money.

If you stop here, it means that all your previous efforts have been in vain.

"I'll try again. ”

Xu Qingyun's voice came from the front.

He was more unwilling than Lin Dui.

He sacrificed the Nine-Star Refining Furnace, thinking that his strength was soaring and he had a great hope of rescuing Xu Jiao, but he was even more unwilling to fail at this time.

Compared to Lin Dui, Xu Jiao is his precious granddaughter.

He cared more about it than Lin Dusk.

Lin Du hurriedly shouted from behind, "Don't keep your hands, hit with all your might." ”

This kind of transparent barrier, he has actually encountered before.

It's just that I have never seen such a powerful barrier that can seal the entire Yin-Yang Valley like this.

In general, to break a barrier, you only need to break the surface with a point.

Use the strongest attack to break the smallest point, even if it is just a small hole, and the barrier will be broken.

Speaking of which, the Nine Star Refining Furnace has indeed suffered a lot by breaking the barrier.

With the same attack power, the attack of the flying sword is undoubtedly much sharper.

Breaking the barrier is also more effective.

It's just that without determining whether Xu Qingyun is true or fake, Lin Duan is also reluctant to take it lightly.

He'll have to look at it again.

After running around for so long, he rushed here, after all, his cultivation was only in the late stage of returning to the void, and now there was not much spiritual power in his body, even if he made a move, he would have to wait until his cultivation was good before he started.

And he is not sure that his attack power can be stronger than Xu Qingyun.

Although Xu Qingyun had only just refined the Nine-Star Refining Furnace, even though the Nine-Star Refining Furnace was not very suitable for breaking the barrier.

He was still not sure that he could do better than Xu Qingyun.

This is the gap in cultivation.

In the case that both of them have peerless spiritual treasures, this huge gap is manifested.

This is also the reason why he and the entire Qingyu Gate besieged Wang Le in the first place, and it was the reason why Wang Le was killed by luck.

But time waits for no one, Xu Jiao's life is less than ten years.

He didn't have time to cross the catastrophe.

Lin Du looked at Xu Qingyun tightly.

I saw that the light of the nine stars flickered again, and it was extremely dazzling.

This attack was even sharper than it seemed last time.

Lin Du was surprised.

Xu Qingyun's current attack power looks even stronger than Wang Ledu at the beginning.

The Nine-Star Refining Furnace is really worthy of being the treasure of the Lingbao Sect.

Xu Qingyun hadn't fully unleashed his power to do this.

Lin Dui had joys and sorrows in his heart, and he had mixed tastes.

But now that we've come this far, there's no turning back.

He only hopes that things will evolve and not come out of his own control.

Rumble.

This time, the transparent barrier trembled even more.

Under the violent shaking, Lin Duan felt that this huge barrier could be broken at any time.

Suddenly.

Lin Dui's eyes widened suddenly.

His eyes were full of surprise and delight.

He was amazed to see a small crack in the transparent barrier.

A small hole the size of a palm appeared.

"Broken. Lin Du shouted happily.

However, as soon as his words fell, the Nine Star Refining Furnace rebounded back, and the small hole that cracked was immediately closed.

A qiē is in the blink of an eye.

Lin Du was dumbfounded.

How so.

Xu Qingyun's face was pale, and his figure bounced backwards far away.

Fortunately, he cultivated strong and was not injured.

"Here's what's going on. Lin Du hurriedly stepped forward to help Xu Qingyun, who was crumbling, and couldn't help but ask in surprise.

"That's the magic of this barrier, not only can it absorb and defuse powerful attacks, but no one can actually break it. Xu Qingyun calmed down before continuing, "Even if there is a crack, it will close soon." ”

"It's so depressing. Qingniu flicked his tail, but there was no depressed look in his eyes, and he said slowly, "Are we going to be stopped outside, we can only watch a lot of treasures inside, but we can't get in." ”

"Naturally, it won't. Xu Qingyun hurriedly shook his head, with a smile on his face, "Actually, I can break the barrier now, which is already a huge surprise, and several of us joined forces before, but we couldn't break the barrier." ”

"What's the use of that. Qingniu didn't give Xu Qingyun any face, and ruthlessly told the truth, "Such a palm-sized crack is difficult for even one of my front hooves to enter." ”

Xu Qingyun's old face turned red, and he almost didn't come up in one breath, and then said, "After all, I'm running in one step, not in the peak state, just now it was just a temptation, and when I get rested, it is estimated that I can break the crack even more." ”

"That's too reluctant. Qingniu said mockingly, "Even if the two of us go in, the crack will heal quickly, what should you do yourself." ”

When Lin Du heard this, his heart was suddenly shocked.

Qingniu's words sounded in his heart like a thunderbolt.

What if the two of them went in and Xu Qingyun didn't come in.

He didn't know anything about this barrier.

In case this is a pit, after he goes in, he can't get out, and Xu Qingyun didn't kill him, which means it's almost there.

In the Yin Yang Valley, there must be more than just one guardian spirit beast of the Tianyuan Fruit, and there must be other powerful spirit beasts, and their strength is even stronger than that of the late stage cultivators.

Together, they can't break the barrier?

It seems so.

On the inside and outside, the difficulty of breaking through the barrier is also different.

Lin Dui's heart was terrified.

I'm afraid that Xu Qingyun will break through the barrier, and it may also be a trap, waiting for him in the back.

Then he suddenly changed his mind.

It's better to let Xu Qingyun go in first.
