In the dark mist, what Xue Zhen was facing was the black tornadoes that were dozens or hundreds of times taller than him, and the black tornadoes of these forms or old women, or evil beasts, or fierce birds, or strong men rushed towards Xue Zhen one after another, Xue Zhen waved the purple Xuan sword in his hand at this time, and waved and danced continuously with the Breaking Wind Technique, like an extremely powerful sword body array, dense and airy, once those black tornadoes arrived, they were immediately completely killed by Xue Zhen, and there was no condensation at all.

However, the black tornado in the more than 100,000 acres of black fog could not be wiped out by Xue Zhen lightly, Xue Zhen naturally understood this, every time he wiped out several wisps of black tornadoes blocking the way, Xue Zhen controlled his body and continued to run out, but those black tornadoes still rushed straight towards him as if he was not afraid of death, and Xue Zhen's pace of travel became more and more difficult.

Seeing this, Xue Zhen coldly looked at the black tornadoes that were blocked around him, at that moment, the solemnity on his face immediately turned into an incomparably cold killing intent, under the killing intent, Xue Zhen frantically injected mana, and the purple Xuan sword in his hand was violently shining, and those black tornadoes were immediately waved nearly two zhang away, and Xue Zhen's wrist twisted slightly, a somewhat obscure and somewhat unfamiliar trick urged, Xue Zhen's purple Xuan sword at this moment suddenly rotated rapidly, and under the injection of powerful mana, the purple Xuan sword immediately turned into a purple red hot wheel, and went straight away, and at this time, Xue Zhen's arm had already broken away from the purple Xuan sword, and in his palm, the two paired long swords showed up again, and it was actually the newly obtained Mi Chen Mandarin Duck Sword.

And at this time, the Mi Chen Mandarin Duck Sword in Xue Zhen's hand has been blessed by him with the Breaking Wind Technique, and when it is wielded, it is not inferior to the Zixuan Sword, but because of the unfamiliarity of wielding the double swords, sometimes some more comical actions will be revealed, but compared to the single sword, Xue Zhen's wielding effect is still better than that of the Zixuan Sword.

In this way, Xue Zhen urged the Mi Chen Mandarin Duck Sword in his hand, and the Zixuan Sword in front of him turned into a purple-red Hot Wheel to open the way, Xue Zhen injected his mana into the Hot Wheels from time to time, and so on, and the speed of Xue Zhen, who was gradually proficient, suddenly increased by three or four times.

That is, half a day is a little more, Xue Zhen doesn't know how many of those things in the underworld he has destroyed, the black tornado, he just appeared on the edge of the pit that was blown out by himself, and I don't know what the reason is, the black tornado here is not too much, and the Mi Chen Mandarin Duck Sword in his hand has also been put away by him, and the Zixuan Sword is in his hand again.

Those black tornadoes were much lighter and much sparser than Xue Zhen's pressure, but Xue Zhen's dignified color hung on his face, at this time, under the urging of the magic trick, a flickering light in Xue Zhen's fingers flashed wildly, and Xue Zhen actually triggered the newly collected Twin Immortal Tomb Forbidden Array, and the forbidden light flashed rapidly, passing through such a small interface crack, and suddenly expanded to two or three hundred zhang inside and outside the deep pit.

At this moment, Xue Zhen did not want to set the size of the Twin Immortal Tomb Forbidden Array at less than three hundred zhang, but because of the pressure of the black tornado outside, if it continued to expand, I am afraid that the huge force of the Twin Immortal Tomb Forbidden Array would increase exponentially compared to what it is now, which is certainly not what Xue Zhen wants.

And Xue Zhen at this moment, wielding the purple Xuan sword in his hand, chasing and slashing the dozens of remaining black tornadoes in the Twin Immortal Tomb Forbidden Array, when the last half-moon inserted into the phantom of the inverted sword flickered and disappeared, Xue Zhen breathed a sigh of relief, obviously Xue Zhen's first step plan has been successful, even though the black tornadoes are slowly released from the interface cracks, but that can no longer constitute a problem, and although the Twin Immortal Tomb Forbidden Array outside continues to emit ripples of forbidden light, it will never be a problem to resist for some time。

At such a moment, Xue Zhen's eyes stared at the interface crack in front of him, the comprehension of the law, a colorless fluctuation of more than five inches, the silk of the law pinched out, and under the urging of Xue Zhen's luck, he went away at an extremely slow speed, pointing to the interface crack in the middle of the air in the deep pit.

And Xue Zhen watched this silk of law slowly go, and he still groaned silently in his mouth between holding his breath, as if he was secretly calculating, the silk of law slowly left, at that moment, when the silk of law reached and had not yet reached it, Xue Zhen was once again extremely skillful in pinching out another silk of law, and it was almost extrapolated without consideration, and the speed of going was obviously more than ten times faster than the previous silk of law. Xue Zhen, who had completed this action, was a little void under his feet, and he retreated violently, and instantly retreated to the edge of the Twin Immortal Tomb Forbidden Array.

"Bang!"

A thick and huge explosion came, and the two filaments of the law just touched and exploded in the interface crack, a dazzling light flashed out, and a black tornado that had just flashed was immediately torn invisible by the power of the law explosion, and the huge impact caused the wind to gust at the interface crack, and the interface crack of a foot size was as if it had not experienced an explosion, it did not expand, nor shrank, which made Xue Zhen frown.

"How is it possible! Either it is stricter, or it is not improved, is it ...... Could it be that the power of the law is too shallow?" Xue Zhen muttered two sentences secretly, with a look of disbelief on his face.

After carefully observing the small half of the tea, there was indeed no change, and Xue Zhen recalled the point of the explosion of Fang Cai, which should also be near the core of the interface crack, could this method not work.

Xue Zhen thought of this, his eyebrows furrowed slightly, and he flashed forward again, and another law silk pinched out, and the chasing law silk exploded in the interface crack again, but the result was still the same, however, Xue Zhen felt something different in the dark, and for the next half a day, Xue Zhen took a little rest and continued to impact such an interface crack with this law chasing explosion.

In the end, Xue Zhen's efforts were rewarded a little bit, and between almost the tenth time the laws chased each other, Xue Zhen saw that the interface crack after the explosion actually changed a little physically.

"Haha! It is indeed possible to narrow this interface crack, and if it continues, the healing of this interface crack is by no means impossible. Xue Zhen's happiness was written on his face, and he said with a hearty smile.

However, when Xue Zhen activated about ten or so times of the Silk of Law Chasing Giant Explosion, an unexpected danger happened!
