Chapter 597

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

As for the evil formation plate, 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, and it seemed that some mysterious changes had taken place under the transformation of this black aura.

Qin Chen worriedly probed for a long time and found that the black aura had no harm or impact on the air-devouring ants and the fire-refining ants, and then returned the fire-refining ants and the air-devouring ants to the black gourd.

Where Ge Peng and the others were, the corpse had already turned to ashes, and only a few storage rings were left, and Qin Chen raised his hand and took it into his pocket.

They are all martial artists who have been trained in the Black Death Swamp all the year round. They must be very rich, right?

If nothing else, just the Heiyu grass that I heard in the Black Order before and the black mulberry root I just saw are already very valuable.

It's just that Qin Chen didn't have much time to check the storage rings of several people. After putting them away, he quickly turned his eyes to where Ku Yunzhi was.

The entire underground ruins are in a mess, with gravel and broken flags everywhere, but Kuyunzhi, which is under the ban, is extremely safe and has not been affected by the previous explosion.

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

At this time, the restriction had been smashed into a corner by the previous Liuhe Sacrifice Refinement Formation. Qin Chen came to the front and carefully observed the restriction.

Restrictions and formations have something in common, but they are much simpler than formations. Some powerful warriors can arrange some simple restrictions, but the real advanced restrictions are not at all simpler than complicated formations, and even more powerful.

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

The defense restriction in front of him is very complicated, and the dense structure makes him dazzled and stronger than he expected.

Even Qin Chen was sure that even in his previous life, he couldn't arrange such a restriction at all.

Moreover, if he hadn't learned a new restraint method in Gu Nandu, Qin Chen even had a feeling that he might not even understand the restraint in front of him.

"Who arranged this?"

Qin Chen's scalp was numb. He had only seen this restriction outside the formation. Although it was very complicated, he thought that it would not be difficult to break it with his own restriction.

Now it seems that this is simply extremely difficult.

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

My heart was suddenly bitter.

"This restriction is indeed very complicated. It is not easy for me to solve it. However, since the Liuhe Festival Refinement Formation can open a gap in this restriction, it means that this restriction has become extremely weak with the passage of time. It's not impossible to break open."

After just being depressed for a moment, Qin Chen soon cheered up.

The prohibition, like the formation, also requires the activation of energy.

A ninth-order formation, once it loses its energy, will lose its efficacy, even worse than a first-order formation.

And the same goes for prohibition.

Qin Chen knew very well that if this restriction was still intact, let alone the Liuhe sacrifice formation, a stronger formation would never break it.

But before the Liuhe Festival Refinement Formation was able to break open the corner of this restriction. Obviously, although this restriction is strong, because of the passage of time, the energy contained in it is likely to have almost dissipated.

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

But these are only for others. Since Qin Chen knows that the ban is flawed, he believes that after his research, it will not be broken.

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

Generally speaking, to break the ban, the magician must first understand the ban, and then break it down one by one, but Qin Chen did not do so, because he knew that the ban in front of him was so complicated, and if he wanted to understand it, it was impossible to do it in a short time. arrive.

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

"Boom boom boom!"

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

Each of Qin Chen's attacks was not a random attack, but a repeated attempt. After about a stick of incense, Qin Chen already had a clear understanding of the entire structure of the ban.

After knowing the complexity of this restriction, Qin Chen took another breath of air.

Although this ban is just an ordinary defensive ban, the complexity is much stronger than he expected.

Knowing the structure of the entire prohibition, Qin Chen began to consciously conduct offensive detection of the prohibition.

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

This is also because the ban itself is missing a corner and is incomplete. Otherwise, it will take at least ten times more time to do this.

At this moment, Qin Chen was actually grateful to Qi Yugang for coming. If Qi Yugang hadn't set up the Liuhe sacrifice refining formation, and accidentally broke the corner of the restriction, he wanted to find the location of the energy source of this restriction. say impossible.

After knowing the source of forbidden energy, everything is simple.

Half an hour later, the restriction in front of him made a bang, and Qin Chen was overjoyed. He knew that he had broken the restriction in front of him. Although the restriction in front of him was still intact, its energy connection had been cut off by himself. can no longer be activated.

Qin Chen cautiously reached out to the Kuyunzhi under the restriction. When he picked the Kuyunzhi, Qin Chen's heart was suddenly full of surprises.

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

The purple Kuyunzhi, lying quietly in Qin Chen's hands, exudes an intoxicating aura.

Just taking a breath, Qin Chen felt that the whole person was fluttering like a fairy, and the real energy in the body was flowing wildly, as if it was about to break through.

Qin Chen no longer hesitated, took out the pill furnace, and began to prepare for refining Ku Yun Pill.

Although Kuyunzhi is taken directly, the effect is also very strong, but after refining it into a medicinal pill, its effect will be improved to the extreme.

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

There is only one Kuyunzhi. In order to prevent the refining failure, Qin Chen was very careful. Every process was extremely careful, even more careful than when refining the ninth-grade medicinal herbs in his previous life.
