It's a pity that because of the sound of the lightning strike, his train of thought was interrupted, and the originally clear formation lines gradually receded.

Of course, he didn't have nothing to gain, at least his current formation cultivation was already able to arrange a second-level formation. Although he has not yet comprehended the rules of the formation path of this immortal cultivation realm, this does not prevent him from slowly deducing, it is just a matter of time.

The lightning strike continued, the roaring sound was still coming, Chen Xuan had been hiding in a cave for a long time, but not a drop of rain had fallen, which made him feel a little strange.

Chen Xuan frowned, perhaps, this time it should not be rain, but some living beings are crossing the thunder tribulation, which is not a good thing.

"Boom!" Another explosion of thunder sounded, Chen Xuan looked over with the place of thunder and lightning, and found that a huge demon beast in the distance rushed up and slammed into the thick thunder arc with a punch.

However, crossing the thunder tribulation is not child's play, even if the body is as strong as a demon beast, it is impossible to resist the bombardment of the thunder, just in an instant, a thunder tribulation fell, directly blasting the demon beast away, falling into a huge deep pit.

Looking at this demon beast that had crossed the Thunder Tribulation, Chen Xuan instantly remembered some questions, in the Immortal Cultivation Realm of this realm, the realm of the Three Heavens of the Earth Realm, there was no Thunder Tribulation at all, and he was able to survive the Thunder Tribulation in the Jindan Period, it was because of his exercises.

Now, this demon beast is actually crossing the thunder tribulation, that doesn't mean that this demon beast is at least an existence in the Heavenly Realm, perhaps, it will not be worse than the Feng Dean of the Heavenly Academy Palace. If it was, with his cultivation in the Jindan period, falling into the hands of this demon beast, how could he have a life?

Not to mention using the Mixed Yuan Bead to break through the boundary and leave, I'm afraid that he has not yet sacrificed the Mixed Yuan Bead and entered the Mixed Yuan Bead, so he was directly pinched to death. For this kind of strong man, even if it is only a moment, it is enough to kill him hundreds of times.

Hurry up, this is Chen Xuan's only thought. Before he could immediately sacrifice the immortal sword placed in the Mixed Yuan Bead, he saw the demon beast that had been blasted into the pit by lightning crawled up and rushed towards him.

Chen Xuan naturally didn't feel that he had offended this demon beast. Presumably, it's because this demon beast can't withstand the thunder tribulation, so it wants to avoid it. Chen Xuan, even more regretful in his heart, knew that this was a demon beast in the crossing, and no matter how much he was drenched in the rain, he would not stay in the cave, but ran away directly.

"Boom...... "This time, three thunder arcs fell, the first two thunder arcs attacked the demon beast covered in sauce-colored mud, and once again tore two scars that penetrated deep into the white bones, and the third thunder arc was blocked by the demon beast with a huge fist again, obviously, this demon beast couldn't dodge the thunder arc of the thunder tribulation at all, where it fled, the thunder arc will go with it, until it is killed!"......

Chen Xuan finally saw clearly, this demon beast was already covered in scars, and if a few more thunder arcs fell, it would definitely be killed directly.

As soon as Chen Xuan thought of this, he had some emotions in his heart, if this demon beast didn't survive the catastrophe and was finally hacked to death, wouldn't he be going to make a big deal?

Before Chen Xuan could turn around on this thought, "Roar! The demon beast let out a terrifying roar, and then jumped to its feet, grabbing both of them at the same time.

"Boom!" The thunder arc blasted down again, and the demon beast directly threw the two people out. The thunder light illuminated the pale faces of the two people, but it did not weaken the power at all, on the contrary, because there were more people, Lei Zheng mistakenly thought that he was a helper, which was even more aggravated.

The increasingly terrifying thunder arc of "Click...... instantly fell on the bodies of these two people, and it had almost no effect, and they were directly blasted into pieces by the thunder arc.

"Roar!" The demon beast roared, and seemed to be getting more and more angry, but it still couldn't resist the erosion of the thunder tribulation, and the "Zizi ......" demon beast was once again scarred by the thunder tribulation, and the white bones had been revealed, even if the strong recovery power was still useless, and he could only stare at it breathlessly, and the breath in the sky was gradually terrifying.

At this time, how could Chen Xuan not know that this demon beast was already at the end of the crossbow, and the next thunder tribulation, if he couldn't get through, he would die. Of course, if it is crossed, it will be a leap into the dragon gate, and the strength will be turned upside down.

"Want to get over? Don't think about it, I interrupted my train of thought before, and I haven't settled accounts with you yet. Chen Xuan smiled faintly, and then, staring at the thunder tribulation that was about to fall with a solemn face, this time it was an opportunity for him, if he succeeded, he would make a big deal, and if he failed, he would not lose anything.

"Boom!" Soon, the terrifying thunder tribulation seemed to have been brewed, and in just an instant, the five thunder tribulations fell, not giving the demon beast a chance to react at all.

"Zizi ......" The demon beast was originally the end of the strong crossbow, and it was baptized by the first three thunder tribulations, and it was even more dying, and before it could catch its breath, the other two thunder tribulations also fell immediately!

"It's now!" Chen Xuan looked at the dying demon beast, and still didn't make a move, but at the moment when the last two thunder tribulations fell, he shot directly!

"Mix the elements into one!" Chen Xuan sacrificed the immortal sword placed in the Mixed Yuan Bead, and the purple-gold sword qi was instantly filled around him, and then, I saw the purple-gold sword qi turn into a thunderbolt storm like a broken bamboo, like a tornado, and the surrounding air burst out with a sound of breaking through the air, under the guidance of Chen Xuan's immortal sword, it was crushed all the way, not giving the other party a chance to turn the tables!

With a sword in hand, I have it in the world!

One sword frost and fourteen states, I can kill everything with one sword!

Under one sword, the world is silent, and any invincible enemy is wiped out under this sword!

"Roar!" The demon beast that had once again survived the last two thunder tribulations had already been unable to bear it, and it was already powerless to support it, and when it saw the swept sword qi, it realized that the ant he had been ignoring had the absolute power of life and death over it at this moment!

It wanted to resist and kill the human it regarded as ants, but it was powerless to support it, so it could only wait quietly for death to come!

"Bang!"

The incomparable sword qi, like a harvester, instantly rushed towards the body of the demon beast, without the slightest accident, and directly killed the demon beast!

"Although this time it seems that the plan is perfect, but in fact it is interlinked, if there is a little mistake, I am afraid that I will die because of it." Chen Xuan muttered. Thinking of the previous layout, there is no trace of pride in my heart, this is a desperate fight.

Walking in front of the demon beast, Chen Xuanduo smiled a little. This demon beast is full of treasures, the muscles and bones of the body can be refined, the essence blood can be washed and the bones can be removed, and the demon pill can be refined into pills, especially this seems to be a seventh-level demon beast, (equivalent to a monk in the heavenly realm), if you add some spiritual grass, you can completely refine the seven-grade heavenly spirit pill!

Of course, in fact, the body of the demon beast not only has these functions, but only a drop in the bucket. However, for these effects, Chen Xuan is enough.

After putting away the demon beast's body, Chen Xuan quickly left. The monster beast tribulation must cause a lot of unnecessary trouble, so it's better to leave first.
