Nangong Feng controlled his poisonous explosion balls to fly around, and after a while, the entire formation space on the ground was full of poisonous explosion balls. After the other party saw it, he knew that he couldn't dodge, so he took out a shield, and then leaned on the edge of the formation, blocked it with a shield in front of him, and also opened his three yuan shield spells.

Nangong Feng saw the other party's defense and knew that it might not be good, but it had been a long time, and his poisonous explosive ball had already had to explode. Then, dozens of explosions followed. The opponent's Yuan Master was indeed unharmed, but he knew that he would not be able to get out of this formation for a while, so he flew back into the cave below.

When Nangong Feng saw it, he drove the Void Hall and flew underground. As soon as he reached the ground, he encountered several powerful attacks, one of which was a lightning attack, which was extremely powerful, of course, it was nothing to the Void Palace.

His consciousness swept over, and he knew that the attack was from the person who had just gone out. However, there is actually a Yuan Master in it, and he is also the peak of the Yuan Master, and his age seems to be older than the Yuan Master who went out just now. The Yuan Master hurriedly collected the Dan Fire he was emitting, walked to the side of the other Yuan Master, and also looked at the Void Palace.

The Yuan Master who went out just now was taken aback when he saw that his attack had not been able to hurt the Void Palace, and he stopped his attack for the time being, and exchanged a few glances with the other Yuan Master.

Nangong Feng's divine sense swept over, and he now knew that these two people were hiding here to refine the Purple Frost Stone. The purple frost stone cannot be cut, but if it is slowly refined, it can still be refined, and after refining, the stone is gone, and the rest is purple frost powder.

The purple frost stone in the middle kept emitting lightning, but it was not strong, and the distance from it was not far. It seems that they are still effective when they are placed underground, but it is estimated that they will soon become stronger, because the hole in the ground has been opened.

In addition, on the purple frost stone, there are many traces of being burned. In terms of size, according to Zuo Ziwen, there are only more than half of them now, and the rest is estimated to have been refined by these two people. Through Mu Ming, he had long known that the purple frost stone could not be put into a storage bag, but the purple frost powder could. Of course, when the purple frost stone is small enough to a certain extent, it is also possible, but the current size is still too large.

He also observed this underground formation, which was not large, only ten zhang square, and was wrapped in his own formation. It seems that they were refining the Purple Frost Stone just now and discovered their own formation, so they went out to check it alone.

The two Yuan Masters of the other side were now standing together, both of them were hiding behind that shield, and they both opened their own Yuan Shield Spells, and those Yuan Shield Spells combined to form a solid defense.

"What's your name?"

"We should have asked you, right?"

Nangong Feng thought about it, too, but he knew that he couldn't tell them what his name was for the time being. He shut up and let the puppet of the Yuan Master next to him use the poison explosion again. And he also put a trigger circle on all the more than fifty poison blast balls. Then he took control of all the poison blasts and attacked the two of them.

The two didn't dodge, and one of them sent out an attack of ice balls, flying swords, etc., attacking these poisonous balls. Then, another person sent out a rain of quicksand and fire, and many small fireballs attacked.

Of course, Nangong Feng didn't have to dodge, after all, he was in the Void Palace, so he closed the spatial passage, controlled the poison blast ball, dodged most of the opponent's attacks, and continued to attack the other party. The opponent had fireballs and ice balls exploding, but they couldn't block all the poison balls. Zuihou still had about thirty poison blasts and attacked the opponent.

The two Yuan Masters on the other side stood there motionless, and it seemed that they were quite confident in their defenses.

Nangong Feng directly activated the activation circle, and all the poison explosion balls exploded immediately. The attack power of the explosion was so high that it was beyond Nangong Feng's imagination. Of course, for the two people who were attacked, it was even more unimaginable. Their shield was directly shattered, and their Yuan Shield Spell was also shattered. Although the two of them tried their best to inject vitality into it, they were not able to stop it.

After the shield was shattered, they paid attention to it, so they were not able to hurt them. However, the shock wave of the explosion still attacked the two of them. The Yuan Master who went out just now was rushed and flew backwards, slamming into the formation behind him. His internal organs were shattered, and Yuan Dan shattered directly in his body. The other older Yuan Master, who was slightly better, was not hit to the front, but was blown up sideways, and also fell heavily on the formation. But he didn't die, just an arm was shattered and dripping with blood, and of course he fainted.

Nangong Feng flew over, directly built a space of about five zhang, accepted this person into this space, took his things, and fed him a big Huanyang Pill. He looked at his left arm and knew that it could not be saved, but he only stopped the bleeding and did not move his arm.

Then the divine sense swept it, picked up the things on the ground, and looked at the body of another person, although it was deflated, but it was estimated that it could be used as a puppet, so he put the body away and soaked it in the pool of the third cave.

The purple frost stone in the middle was also blown aside. He flew over and used the Void Technique to receive the Purple Frost Stone into the Void Palace.

Then he didn't accept this formation from them, but flew out and collected his own formation. Then, he didn't stop, and flew directly out of the Zuojia formation and flew towards the Valley of Medicine and Fire. As for the battle between the Zuo family, the Liu family, and the Giant Sword Gate, he didn't care. Anyway, his main things are all in hand, and because of what Zuo Ziwen, Liu Tianli and Liu Jingming did, he didn't have a good impression of the Zuo family and the Liu family.

On the way, he first dug a hole of about twenty zhang in the middle of the mountain, put the purple frost stone in it, and built a space to enclose the hole.

He thought about the explosion of the poison blast just now, and it seemed that there was a difference between the explosion of the poison blast ball and the explosion of the poison pop bead. When the poison pop explodes, something hard will be blown out, and if it touches a person, it will blow up the person's corpse. However, the poison blast ball is different, the poison blast ball emits a shock wave, so it will blow away the corpse of a person, but it usually does not blow up.

So it seems that it is better to use the poison blast ball, if you can use the poison blast ball in the future, you can't use the poison pop bead, otherwise the human corpse will not be able to refine the puppet.

Just as he was thinking, he found that the peak Yuan Master had already woken up, and it seemed that the effect of that Great Returning Yang Pill was still quite big, and he woke up so quickly. He came to the space of that peak Yuan Master and looked at this Yuan Master coldly.

This Yuan Master is not afraid, although his vitality has not recovered now, and the storage bag and equipment on his body have also been taken away, but he still has a natal treasure in his body. In addition, this Yuan Shi is not a person who is afraid of death. He first looked around and knew that he had been moved, then at his arm, and simply ripped off his left arm with his right hand. Thrown aside, set another fire, and burned.

Then, he looked at Nangong Feng and asked, "What kind of cultivation is Yuanyou, how can he have such a strong ability?"

"I, Yuanshi, Yuanshi is on the fourth floor. ”

This Yuan Shi glanced at Nangong Feng carefully, and what he saw was still about the first level of Yuan Shi. He didn't understand how a person could hide his cultivation to such an extent, because in his concept, any method of concealing it was to make it impossible for the other party to see his cultivation, and he didn't know how to directly display his cultivation as such. He understands Nangong Feng's appearance, after all, some people will eat Baoyan Dan when they are very young, so it is not strange to have such a young appearance. He looked at the fog around him again, shook his head, and said, "I don't believe it. ”

"Believe it or not. ”

"What did you do to my Zuo family?"

After hearing this, Nangong Feng felt that this person was more concerned about the Zuo family, so he said: "I haven't done anything to the Zuo family yet, but whether I will do anything or not depends mainly on your performance." ”

This Yuan Master was stunned for a moment and said, "What do you need, say it, as long as you don't kill the Zuo family, it's easy to say anything." ”

"Okay, let me ask you a few questions first, what is your name, and the peak master who is with you, what is your name?"

"My name is Zuo Chongming, and the other person is Liu Dibing, the ancestor of the Liu family. ”

Nangong Feng knew that his name was the same as the name Zuo Ziwen said. He asked again, "You brought this purple frost stone back?"

"That's called the Purple Frost Stone?"

Nangong Feng looked at him and did not answer. He continued: "We generally call it purple calcium carbide, but it doesn't matter what it's called. That's right, I brought it back. ”

"Before you brought it back, you didn't know that it was the minerals of the Giant Sword Gate?"

"Yes. ”

"Know you still have it?"

"This is for the prosperity of the family, even if I offend the Giant Sword Gate, I will bring it back, not to mention that our relationship with the Giant Sword Gate is not good. ”

After hearing this, Nangong Feng understood a little, it seems that the Zuo family and the Liu family have been fighting with the Giant Sword Gate for many years. Of course, this has nothing to do with him, so he said: "But now that the Giant Sword Gate is attacking, do you have any way to deal with it?"

"You were invited by the Greatsword Gate?"

Nangong Feng thought for a moment, then nodded and said, "Yes." ”

"What we originally wanted was to hold on for a period of time, take advantage of this time, refine two swords with lightning attack ability, and then use these two swords to threaten the Giant Sword Gate to retreat. However, in the process of refining the sword, we found that the purple electric powder was not enough, so we came down to refine the purple electric stone again. ”

"So you originally planned to wait for these two swords to be refined, and then start a war against the Giant Sword Gate?"

"Yes. ”

Nangong Feng thought for a while, and it seemed that he didn't have any other problems, so he said, "Okay, in that case, I can ignore the battle between the two of you and the Giant Sword Gate." However, I have three conditions, and if you can meet them, I will leave. ”

"What conditions, you say?"

"First, I need to make ice beads, you write it out for me. ”

"There's no problem with that. ”

"Second, I need you to remove all your things from the sacrifice, of course, I don't want your natal weapon. ”

"Yes. ”

"Third, you help me continue refining the Purple Frost Stone, I need the Purple Frost Powder. ”
