Looking at the big pit several zhang deep in front of him, it is hard to imagine that there was a small tungsten iron hill dozens of zhang high here.

Harley blinked his eyes and turned to look at Di Bai to the side.

Di Bai also blinked and turned his head to look at him, and the two stared at each other for a long time.

"Are you alright?"

In the end, it was Harley who spoke first.

Although he wanted to say that he was fine, the feeling of a splitting headache hit him like a tide, and Di Bai could only sit down with his head covered and meditate to recover his spiritual sense.

As for Taixuan, the moment the sword lotus dissipated, it turned into a sword light and flew back into the sword seal. Without Di Bai's spiritual control, this guy doesn't want to stay outside for a moment, and he feels like a house in the sword.

After another hour or so, when Di Bai felt that his head didn't hurt much, he finished pranayama.

"What did you just do?"

Seeing this, Harley hurriedly jumped over, his little face full of doubts.

Di Bai smiled bitterly at the moment, the scene just now really had a lot to do with him.

"I said that Taixuan taught me, do you believe it?"

Seeing Harley's even more puzzled look, he had to tell him in detail about the process he had just experienced.

It happened the next moment when Taixuan broke into the tungsten iron mountain, and he originally felt that this blow was indeed quite powerful like Harley, and even wanted to applaud or something.

However, he didn't expect Taixuan to ask him if he wanted to activate the sword formation. Of course, it was impossible to really speak or anything, it was just a feeling, as if asking him if he had opened the sword array.

And he didn't think much about it at the time, so he motioned for Taixuan to start the formation. Who knew that the next moment, his spiritual sense was instantly drained, and then the scene just now happened.

Harley's face tensed as he listened, and he thought for a moment before he spoke slowly.

"I don't know why it is now, but even the Immortal Sword and Thunder Technique of Zhenlei has never been like this."

Hearing Harley say this, Di Bai panicked. What's going on, can't you become a flying sword?

"Why don't I call Taixuan out to take a look?"

He looked at Harley and asked tentatively.

"Hmm!"

Harley snorted heavily in a nasal voice.

Without saying a word, the true qi that had just recovered in his body was poured into the sword seal by Di Bai again.

Then I saw his sword trick pinched, the silver-blue sword pattern in the center of his eyebrows flashed, and a glazed flying sword was quietly suspended in front of him, it was Taixuan.

Carefully looking at Tai Xuan, who was hanging in the air, his body was surrounded by thunder and sword rays, and bursts of sharp qi rushed to his face, no different from usual.

Seeing this, Harley also flew over quickly, first circling around Taixuan several times, and then touching its blade with his hand, but in the end, like Di Bai, he didn't notice anything unusual.

"What to do?"

Di Bai looked at Harley, this matter is not a matter of dragging on.

"Why don't you use it again?"

Harley rubbed his little hands together, a hint of excitement in his voice.

Looking at Harley's slightly excited look, Di Bai always felt that this guy was a little gloating.

But after thinking about it, it seems that this is the only way.

So, the two of them circled around the small cave again, and this time found a relatively large mountain bag, which was hundreds of zhang high.

Looking up at the big mountain bag in front of him, Di Bai looked at Harley floating on the side.

"Is it high enough?"

Halley nodded.

"Enough!"

Then, the two of them retreated a full few hundred meters, and this distance was exactly the best distance for Di Bai to cast his flying sword, and it was also the most powerful distance.

Looking at the mountain in front of him, Di Bai summoned Taixuan. It looked quite satisfied, and after leaving the sword seal, it had been circling and dancing around Di Bai, looking full of spirituality.

He calmed the excited Taixuan a little through his spiritual sense, and then manipulated it to stab towards the mountain bag as he did just now.

"Boom"

With a low sound of breaking the air, Taixuan was wrapped in thunder and lightning and the sword light arrived in front of the mountain bag in an instant. Then, as easily as before, he tore open the rocks and penetrated deeply.

It's that feeling again, as if asking yourself if you want to open the sword formation. He deliberately asked what was going on, but received no response.

In desperation, Di Bai beckoned to Harley, and then took the initiative to convey all his spiritual knowledge to Taixuan. In order to find out what was going on, he deliberately set aside a very subtle spiritual sense for observation.

And in the next moment, that headache came again. This time it was even worse than before, and he only felt as if his head was cracking, and the sharp pain was like a monstrous wave that frantically pounded his endurance.

But he didn't fall down, but stared at the mountain bag in front of him. At that moment just now, although his spiritual sense was torn apart in an instant, he vaguely saw something. And he has a hunch that this time the movement will not be small.

Seeing Di Bai like this, Harley's gaze on him was also full of worry.

Waving his hand to indicate that he was fine, Di Bai sat down cross-legged and waited quietly for that moment to come.

Tai Xuan didn't disappoint him, and with the humming sound of the sword qi breaking through the air, he saw a brilliant transparent sword lotus blooming brilliantly from the ground, and then enveloping the mountain that was nearly a hundred zhang high.

Immediately afterwards, the azure thunder dragon and the stegosaurus formed by the sword qi reappeared, but at this time, the length of the two was not the same as the last time, and it was hundreds of zhang long.

I saw the Brontosaurus and Stegosaurus with hundreds of feet in length wrapping around the peak, and the rather huge peak immediately turned into pieces of crushed stone the size of a fist.

In just three breaths, such a large mountain was instantly broken down into pieces of rubble, and the power was truly breathtaking.

As the sword lotus that had completed its mission gradually dissipated, the two dragons also dissipated into the air, and only the pile of rocks in front of them silently told everything that had just happened here.

At this time, Di Bai could no longer bear the tidal pain, and almost entered a state of meditation in a semi-coma.

Feeling that his spiritual space was squeezed dry, and there was not even a little spiritual space left, he really wanted to cry without tears. Meditate slowly, this time it will not be able to recover in an hour or two.

It took six hours, half a day, for Di Bai to wake up slowly.

"Do you know what's going on?"

As soon as he opened his eyes, Harley pounced.

Seeing that he didn't care about his own safety at all, Di Bai's face instantly darkened. See, is this what a qualified book spirit should do?

Ignoring Harley, he took it upon himself to summon Taixuan again. Not to mention, the number of summons is too much, and he doesn't know if it's a psychological effect, he feels that the speed is a lot faster.

Holding Taixuan in front of him, Di Bai carefully looked at the body of the flying sword again. But this time, he didn't just use his eyes, he also used his spiritual sense.

The spiritual sense lightly touched the sword body, and slowly probed along the hilt towards the tip of the sword, carefully understanding every detail of Taixuan. And so on and so forth, back and forth several times.

"Got it"

Di Bai's eyes burst with a gleam.

I saw him turn Taixuan upside down, holding the hilt of the sword in his hand, and the tip of the sword was pointing downward. Then his fingers rested on the spine of the sword, and the true qi in his body continued to flow towards it.

With the influx of his true qi, while the sword qi of the sword body became more and more intense, the surrounding space also had a faint feeling of being divided.

Feeling such a scene, Di Bai's face was overjoyed, and he increased the intensity of the injection of true qi.

Although Harley on the side had not communicated with Di Bai, looking at his current movements, he also vaguely guessed something. So he didn't speak, just waited quietly.

Finally, the injected true qi seemed to reach a limit.

I saw a silver line on the spine of the Taixuan Sword, and then the two of them felt that the space around them was suffocated, and an extremely sharp aura immediately rushed to their faces.

Seeing this, Di Bai not only immediately let go of his hand that injected true qi, but also slapped Taixuan towards the ground to directly disperse the true qi inside.

"Do you see clearly?"

Di Bai, who had continuously summoned and infused his true qi, looked at Harley breathlessly, and that moment just now was enough for the other party to see the lines clearly.

Harley nodded solemnly.

"What's it?"

Seeing Harley's face so solemn, Di Bai's heart was also groaning, thinking that there should be no real moths.

"Celestial Array"

Harley spat out four words.
