After observing the mysterious rusty sword for a long time, but still finding nothing, Qin Chen could only helplessly put away the mysterious rusty sword.

As for the evil array, after being absorbed by the black aura, it also turned into a cloud of powder, and there was nothing left.

Only the Fire Refining Insect and the Air Devouring Ant still had an evil aura on their bodies, and it seemed that under the transformation of this black aura, some mysterious changes had taken place.

Qin Chen probed worriedly for a long time, and after finding that these black breaths did not have any harm or impact on the air devouring ants and fire refining insects, he retracted the fire refining insects and air devouring ants into the black gourd.

Where Ge Peng and the others were, their bodies had already turned into ashes, and only a few storage rings were still left there, which were raised by Qin Chen and put them in his pocket.

They are all martial arts powerhouses who have been trained in the Black Death Swamp all year round, so they must be very rich, right?

Not to mention anything else, just the black jade grass that I heard in the Black Monk before, and the black olive root that I just saw, are already extremely valuable.

It's just that Qin Chen didn't have much time to check the storage rings of a few people now, and after putting them away, he quickly looked at the location of Ku Yunzhi.

The entire underground ruins were in shambles, littered with rubble and cracked array flags, but Kuyunzhi, who was in the middle of the ban, was extremely safe and had not been affected by the previous explosion.

At this time, Qin Chen was even grateful for the defensive prohibition, if it weren't for this defensive prohibition, it would be impossible for Ku Yunzhi to be safe and sound.

At this time, this prohibition had been blasted open by the previous Liuhe Sacrifice Refining Array, and Qin Chen came close to observe the prohibition carefully.

Prohibitions and formations have something in common, but they are much simpler than formations, and some powerful martial artists can arrange some simple prohibitions, but the real high-level prohibitions are no simpler than complicated formations, and even much stronger.

Originally, Qin Chen thought that this prohibition was not a problem for him at all, but after he saw the entire prohibition thoroughly, he immediately knew that he was very wrong.

The defensive prohibition in front of him was very complicated, and the dense structure made him dazzled and unexpectedly strong.

Even Qin Chen was sure that even if he was in his previous life, he would not be able to arrange such a prohibition at all.

Moreover, if it weren't for learning a new prohibition method in the ancient southern capital, Qin Chen would even have a feeling that he wouldn't even have the possibility of understanding the prohibition in front of him.

"Who laid this out?"

Qin Chen's scalp was numb, he had only seen this prohibition outside the formation before, although it was very complicated, but he thought that with his own forbidden cultivation, it was not difficult to break it.

Now it seems that this is extremely difficult.

Qin Chen's heart immediately sank, he didn't expect that after experiencing this life and death, there would be such a difficult problem before he got Ku Yunzhi.

My heart was suddenly bitter.

"This prohibition is indeed very complicated, and it is not easy for me to unravel it, but since the Liuhe Sacrifice Refining Array can open a gap in this prohibition, it means that this prohibition has become extremely weak with the passage of time, and it is not impossible to break it. ”

After only being depressed for a moment, Qin Chen soon came to his senses.

Prohibitions, like formations, also need the urging of energy.

A ninth-order formation, once it loses its energy, will lose its effectiveness, and it is even inferior to a first-order formation.

And the ban is the same.

Qin Chen knew very well that if this prohibition was still in a complete state, let alone the Liuhe Sacrifice Refining Array, a stronger formation would not be able to break it in the slightest.

But before, the Liuhe Sacrifice Refining Array was able to break the corner of this prohibition, and it was obvious that although this prohibition was strong, because of the passage of time, the energy contained in it was likely to have almost dissipated.

If you change to another formation master, even if there is only a little bit of forbidden energy left, you can't easily break it.

But these are just for others, since Qin Chen knows that this prohibition has flaws, I believe that after his research, it will not be impossible to break the formation.

Thinking of this, Qin Chen immediately calmed down and studied the formation in front of him.

Ordinary formation mages must first understand the prohibition and then break it down one by one, but Qin Chen didn't do it, because he knew that the prohibition in front of him was so complicated, and if he wanted to figure it out, it would be impossible to do it in a short period of time.

The first thing he did was to attack the prohibition in front of him.

"Boom, boom!"

In an instant, the entire underground ruins once again resounded with a violent roar.

Every time Qin Chen attacked, it was not a random attack, but an attempt again and again, and after about a stick of incense, Qin Chen already had a clear understanding of the entire forbidden structure.

After knowing the complexity of this prohibition, Qin Chen gasped again.

Although this prohibition was just an ordinary defensive prohibition, the complexity was much stronger than he expected.

Knowing the structure of the entire prohibition, Qin Chen began to consciously attack and probe this prohibition.

After another half a pillar of incense, Qin Chen finally found the source of this forbidden energy.

This is still because the prohibition itself is missing a corner and is mutilated, otherwise it would take at least ten times more time to do this.

At this moment, Qin Chen was actually grateful in his heart that Qi Yu had just come, if it weren't for Qi Yugang who had just laid down the Liuhe Sacrifice Refining Array and broken the corner of this prohibition by mistake, he wanted to find the location of the source of this forbidden energy, it could even be said that it was impossible.

Once you know the source of forbidden energy, everything is simple.

Half an hour later, the prohibition in front of him made a popping sound, Qin Chen was overjoyed, he knew that he had broken the prohibition in front of him, although the prohibition in front of him was still intact, but its energy connection had been cut off by itself, and it was impossible to be activated again.

Qin Chen cautiously stretched out the forbidden bitter yunzhi, and when he picked the bitter yunzhi, Qin Chen's heart was suddenly full of surprise.

It took so long and so much effort to finally succeed.

The purple bitter rhyme mushroom lay quietly in Qin Chen's hands, exuding an intoxicating aura.

Just by taking a breath, Qin Chen felt that his whole person was fluttering, and the true power in his body was flowing wildly, as if he was about to break through.

Qin Chen immediately stopped hesitating, took out the Dan Furnace, and began to prepare for refining the Bitter Yun Pill.

Although Kuyunzhi is taken directly, the effect is also extremely strong, but after refining it into an elixir, its effect will be improved to the extreme.

After a while, after all the preparations were completed, Qin Chen took a deep breath, directly sacrificed the Qinglian Demon Fire, and began to refine. =

There was only one bitter Yunzhi, in order to prevent the failure of refining, Qin Chen was cautious, and every process was extremely careful, even more careful than when refining the Nine Rank Pills in his previous life.
