The power of the dragon snake sword that has become the best spirit treasure has really increased greatly, but the requirements for mana are also very large, Yang Xiao continues to take high-quality pills, and his own mana is already considered strong in the same level, but using the best spirit treasure, he can still feel that the loss of mana around his body is quite fast, and if it goes on like this, I am afraid it will be difficult for him to persist in fighting for a long time.

However, after one wave of those winged centipedes perished, another wave came quickly, and it seemed that they could not be killed, which made Yang Xiao feel extremely shocked.

How could there be so many powerful mid-level spirit beasts in the sea of beasts?

No, there is something wrong with these spirit animals.

Yang Xiao quickly sensed the problem, this wave of spirit beasts appeared in the sky, and Yang Xiao killed so many spirit beasts, the corpses on the ground were only covered with a layer, and they did not increase again. No matter how many spirit beasts are killed, those corpses will no longer increase.

That's the problem, none of these spirit beasts are real, but all of them are fictional.

"It's just that this fiction is also a little too real. Yang Xiao smiled bitterly. He could even hear the sound of the spirit beasts' teeth grinding, and the sound of the wind from the instigation of their wings, which felt so real that it was hard to imagine that an illusion could be so real.

However, Yang Xiao thought so in his heart, he didn't dare to slack off in his hands, he didn't dare to guarantee that if he didn't attack these spirit beasts, these spirit beasts would not really hurt himself, or would not hurt himself at all.

After all, everything was too real, so he had to deal with it desperately as if he were facing a great enemy.

"It seems that this illusion is consuming one's mana, and when one's mana is exhausted, I'm afraid it will be the most dangerous time for oneself, but now, we must not wait like this." Yang Xiao naturally had a plan in his heart, and let go of his divine sense, he just wanted to find out the weakness of this illusion.

However, to his surprise, there seemed to be a layer of pink mist around this illusion, and it was difficult for his divine sense to probe deeper into the surrounding fog, and it was difficult for him to know where the person who performed the illusion was.

In this way, Yang Xiao could only test it, and after he destroyed a wave of centipede spirit beasts, he would attack with all his might towards the place where the pink mist around him was the thickest.

With a "boom", under Yang Xiao's full operation, the Sword Spirit Realm instantly tore a big hole in the distant sky. At this time, he saw a large number of butterfly-like spirit beasts fluttering with wings turned into ashes under his slash. However, the number of these butterfly spirit beasts seemed to be extremely large, and soon, some of the surrounding ones were replenished, filling the vacant place, and this piece of canopy was sewn up again.

This time it really had some effect, allowing Yang Xiao to see some of the situations outside the illusion, but he still didn't quite understand whether the butterfly spirit beasts around him were real spirit beasts or part of the illusion.

However, at this time, Yang Xiao naturally did not hesitate, the blow just now had obviously shaken this illusion, and even those centipede spirit beasts that appeared frequently did not appear again this time. Even so, Yang Xiao naturally couldn't think that this illusion was so capable, obviously, this illusion was still preparing some kind of big killing move, if Yang Xiao couldn't break out of the formation, then I'm afraid the consequences would be difficult to imagine.

Striking while the iron was hot, Yang Xiao quickly took out the newly refined Thunder Emperor Scepter, and with the thunder and lightning mark, several thunder and lightning dragons were sent out to attack in several directions that Yang Xiao had identified, and at the same time, the realm of the sword spirit was also shrouded in other directions.

Although this split attack reduces the power of the attack, it can attack in all directions at the same time, which should be more effective in breaking the illusion. Of course, these directions that Yang Xiao identified were the result of his careful exploration, and this was the core of what he believed to be the illusion, that is, the place where the pink smoke gathered the most.

With Yang Xiao's earth-shattering attack, the illusion that surrounded him also collapsed in an instant, and the original palace was also shattered inch by inch, revealing the original face of the original beast sea.

At this time, Yang Xiao naturally already knew how the illusion was composed, it turned out that this illusion was not artificial, but the countless pink butterflies around him joined forces.

I saw butterflies vibrating their wings, and they sent out small illusions, and countless small illusions were superimposed on each other to form a huge illusion castle. The small illusions emitted by these individual butterflies are not very powerful, but when all the illusions are stacked on top of each other, the power is really huge. If it weren't for Yang Xiao's understanding of illusion, which allowed him to see through illusion, I'm afraid he would really be stuck in illusion and couldn't extricate himself.

"What a powerful illusion superposition" Yang Xiao exclaimed, he originally thought that someone had set up an illusion to deal with him, it turned out that these pink butterflies were ghostly, although each of these pink butterflies was just a low-level spirit beast, it didn't seem to have too many attack surnames, but the combination of countless butterflies was quite powerful, if it weren't for Yang Xiao's latest refining of the best spirit treasure, I'm afraid it would be difficult for him to get out of this illusion.

"It's better to get out of here." Yang Xiao thought about it, so he flew quickly and raised dozens of feet, and then flew towards a place where butterfly spirit beasts were sparse.

When he flew away from the butterfly spirit beast group, he also solved some residual butterfly spirit beasts by the way, these spirit beasts were really the same as he thought, except for illusion, there were no other special skills, he could easily kill them, but these spirit beasts were too many, dense, hundreds of thousands of millions, it was difficult to kill them all, after killing some, soon others would be replenished, it seemed that these spirit beasts did not seem to have decreased, so that anyone would feel that their scalp was numb.

Even, if Yang Xiao took a step later this time, the illusion array that had been broken would be combined by these butterfly spirit beasts again, and the new palace and castle would be formed again, and even if Yang Xiao was still in place, it would be possible to trap him again.

After flying a little farther, Yang Xiao turned around and saw that the pink figures gathered again, forming a pink smoke, but when the smoke also gathered more and more, the smoke disappeared again, replaced by a golden palace.

Obviously, the Butterfly Spirit Beast's illusion array was activated again, waiting for the next unlucky one. (To be continued.) )
