Liu Pu looked at the huge energy shield, a trace of solemnity flashed in his eyes, and said: "We don't know how this shield was formed, when we first discovered the ancient city, it didn't exist, but it wasn't just someone who triggered a mechanism somewhere, this energy shield was formed, it was very powerful, everyone of us present tried it one by one, and there was no way to break it." ”

Su Qianwei sneered and said, "It seems that our Qin Xiao Sect still has to thank this mysterious energy shield that suddenly appeared, if it weren't for it, I'm afraid you wouldn't have kept the agreement, and you would have gone in to explore it in advance." ”

Liu Pu said with a smile: "Hehe, the heavy treasure is in front, who is willing to lag behind? ”

Su Qianwei didn't answer, Liu Pu continued: "It's just a small matter, let's not get entangled in it anymore, otherwise it will affect the harmony of the two sects, and now the first thing we have to solve is how to break this energy shield, and then we can enter the center." ”

Su Qianwei looked at the blue-black energy shield and muttered for a long time, and said, "I'll try it first." ”

As soon as she finished saying this, everyone hurriedly retreated, as if to avoid some danger, Zhan Chen was curious when he saw this, but everyone else retreated, he would not stay in front stupidly, so he also followed everyone back, and retreated about three hundred meters before everyone's footsteps stopped.

At this time, the momentum on Su Qianwei's body began to climb steadily, and suddenly there was a seal on her hand, and she screamed: "Wind Dragon Technique!" The color of heaven and earth suddenly changed, and countless heaven and earth vitality gathered in front of her, condensing into a green dragon with a length of three thousand meters, and swooped towards the energy shield.

The Wind Dragon Technique is the best Wind Attribute Dao Technique of the Immortal Rank, this level of Dao Technique can only show its true power in the hands of the Enlightened Ancestor, and the five-hundred-meter-high energy shield seems to be vulnerable in front of the huge Wind Dragon, but the next scene completely shocked Zhan Chen.

The blue-black energy shield suddenly bloomed with ten thousand dark thunderbolts, forming a huge "thunder mountain", and the thunder mountains burst out with electric rays thicker than pillars, slashing towards the wind dragon, and will tear them into countless pieces, and in the blink of an eye, the powerful Dao technique that Su Qianwei cast collapsed. And the shock wave formed by the confrontation between the two swept over, so that Zhan Chen felt that his feet were unstable, his face was painful, and he couldn't help but sigh in his heart, such a strong power, if I didn't retreat with the others just now, and stayed in place, I'm afraid I would have suffered a little bit of a slight injury at this time.

Seeing that her Dao technique had no effect, Su Qianwei was also stunned, retreated to Liu Pu's side and said, "Elder Liu, have you ever tried to shoot together?"

Liu Pu replied: "I've tried, but this energy shield is stronger when it is strong, and our cooperation can only cause it to rebound even more, and for this reason, many disciples of the sect have also been injured." ”

Su Qianwei pondered for a while again, and muttered, "It seems that the idea of breaking the formation with force is not advisable. ”

Liu Pu said again: "That's why I asked you if there is a better way, isn't your Qin Xiao Sect quite a bit of research on various formation and Taoism?"

Su Qingwei stared at the shield for a while, and finally showed a triumphant smile and said, "I have a way." ”

"Tell me quickly, what is it?" Liu Pu and the others asked anxiously.

"That's to break the formation. ”

"Oh, so you already have a formation that can restrain it?"

"Of course. Su Qianwei said as she took out a formation disk from the storage ring, loaded it with immortal stones, and threw it into the air, a huge spirit array unfolded, with a diameter of 100 meters, but even so, this spirit array still seemed so small in front of the energy shield shrouded in the center of the entire city, making people wonder if it could successfully break through the energy shield in front of the formation.

Liu Pu asked, "Elder Su, what kind of spirit array is this, can it break through the defensive spirit array?"

Su Qianwei smiled: "Just look at it, this spirit array of mine is a 'big stomach king'." ”

While she was talking, the formation diagram of the spirit array released by Su Qianwei had already collided with the energy shield, and unlike the imagination of the people present, there was no fierce scene of Mars hitting the earth at all, on the contrary, the two spirit arrays seemed to be able to live in harmony.

However, the pupils of all the people present shrank suddenly, because they saw that a stream of black energy was being continuously extracted through the contact surface by the spirit array released by Su Qianwei.

Seeing that everyone was surprised, Su Qianwei said proudly: "See, my spirit array is called the Sky Devouring Spirit Array, its only function is to devour energy, as long as there is sufficient supply, it can be infinitely amplified!"

"Elder Su, if what you said is true, then this spirit array is really terrifying. ”

"Yes, this Sky Devouring Spirit Array can be said to be the nemesis of other Spirit Arrays, because all Spirit Arrays must have sufficient energy supply to operate, and the Sky Devouring Spirit Array can cut off the energy supply of all Spirit Arrays. ”

"Then can this spirit array also absorb the immortal elements of our immortals?" Liu Pu asked worriedly.

Su Qianwei shook her head and replied, "This spirit array is not good for people, because its absorption ability is very weak and its speed is very slow at the beginning, and we immortals can dodge it as long as they dodge it." ”

Listening to her, Liu Pu and a few other enlightened ancestors breathed a sigh of relief.

The Sky Devouring Spirit Array continued to devour the energy of the black energy shield, and its scale became larger and larger, and the larger the scale, the faster the energy absorption would be.

Gradually, everyone could clearly feel that the energy shield had become thinner, and at this moment, they only heard Su Qianwei shouting, "Everyone attack together!"

Only then did everyone react, and they all began to use their most proud Dao technique, hundreds of attacks, raining down on the energy shield, and finally the energy shield was finally overwhelmed and shattered, like a punctured balloon.

Breaking through the energy shield, the things that were protected in it were gradually revealed- A huge castle with a height of more than three hundred meters was presented in front of everyone, this ancient castle was pitch black, but the surface shimmered with a crystal-like luster, obviously using rare refining materials, it looked mysterious and magnificent.

A group of people hurried to the front of the ancient castle, looked up, and saw three dark gold ancient characters engraved above the gate of the ancient castle "Guiru Fort".

Liu Pu used his immortal sense to probe around, but found no traps, and then said: "Guiru Fort, it seems that it is the name of this ancient castle, let's go in." With that, he stretched out his hand and pushed the gate of the castle open.

With the sound of clicking, a dark passage gradually appeared in front of everyone's eyes.
