The serial killing array in front of him, although it is quite complicated, but it is for ordinary formation mages, Cao Yu not only digests the inheritance of Tianxuanzi very thoroughly, but also reads a lot of books about formations.

Especially in the Danta of Frostfall City, where there are a lot of books, there are naturally not a few formation-related ones.

Take two steps to the left, and the miniature array disk that has been arranged in his hand has been carved into a piece of jade, and now the killing array to be broken, whether it is the difficulty of cracking or the requirements for the formation plate, has increased, so he needs to use jade to burn the array disk, so that the array disk will not disappear so quickly.

After entering that array, the crossbow that was to be triggered first suddenly made a click, and the controlled formation failed, so naturally there was no power source, and it fell directly to the ground with a clang.

Cao Yu was not complacent, this was only the first step, he needed to crack this formation step by step, and it would take a lot of energy.

He took two steps forward to the right again, constantly changing the law in his hand at the same time, and held a piece of jade in his left hand, which was obviously prepared for the next array.

This time the bow and arrow to be cracked are not ordinary bows and arrows, to be more precise, they are more like heavy crossbows, much larger than repeaters, and each arrow on the string of the arrow has a green liquid smeared there, it is obvious that there is a poison there.

It seems that the person in charge of this arrangement, or the person in charge of the Pan family, is really painstaking, and with such an insidious trick, it is very likely that it is the masterpiece of Pan Lanmu's old thief.

After all, the Blood Demon Array was still arranged by himself after all, and he naturally had these vicious methods at his fingertips.

With a flick of his fingers, the burned array disk was hit by Cao Yu just right into one formation.

"Buzz!"

The killing array was partially cracked again, but this time the giant bow and arrow did not fail, but shot straight in the direction where Cao Yu was.

Fortunately, his soul power was always paying attention to the movement in front of him, and the previous phantom array was cracked, otherwise this hand alone would have killed Cao Yu on the spot.

One sideways, dodging the first bow and arrow, flashed again, and dodged the second wave.

"Ding, ding, ding!"

The giant bow and arrow shot at another stone wall, and the powerful force actually shot directly into the stone wall, and at the same time, the stone wall was corroded by severe poison, making a sneering sound, and after a while, there were only a few gaps, seeing this scene, Cao Yu's face turned cold, and his heart once again comprehended the viciousness of the people of the Pan family.

Originally, he felt a little guilty when he saw those beheaded heads in that hall, but when he saw the Pan family acting in such a vicious style, the guilt in his heart had almost disappeared.

After spending two sticks of incense again, the insidious traps of the chain formation were broken by him one by one, and finally reached the last sword formation.

This is the trickiest part!

The sword array, there is a terrifying place, that is, if you don't hit the target, you will never disappear!

This is somewhat similar to the attachment of sword cultivation.

Rubbing his chin, Cao Yu was really difficult to start for a while, what he was most afraid of now was whether this sword technique would stop when it saw blood, if that was the case, wouldn't he have to see red?

He didn't want to be hurt anymore because he didn't have masochistic tendencies.

He thought to himself that if only there was a puppet now, he could let the puppet withstand the attack for him!

After combing through it from beginning to end, he felt as if he had missed something.

Since the sword array can not stop until it reaches its goal, it must have a root for its tracking, and this root is naturally the breath of a human monk.

"Hey, what if you use the phantom array to confuse this sword array?"

After all, the formation is dead, and people are alive, and the formation master who arranged this formation at the beginning was naturally very thoughtful.

But there must be a mistake in the hundred secrets, and even the most perfect formation mage does not dare to guarantee that he will be able to arrange the perfect formation in the world.

It may be perfect from one point of view and there are no loopholes, but from another angle it may be full of holes.

Thinking of it, he decided to give it a try, Cao Yu's idea was this, using his true element to condense a phantom similar to his body in the phantom array, of course, his breath should be in it, and then go to trigger the sword array, as long as the breath of his body is not within the range of the killing array, the sword array will naturally only attack the phantom.

The thick true element came out of the body, and Cao Yu, the perverted true element, was extremely full, if it was other monks, he couldn't use this method at all, after all, his strength didn't allow it.

At the same time, the phantom array that was here before was waved by him and put a few arrays out again.

"Woohoo!!"

When Cao Yu's phantom was triggered within the range of the killing array, it was indeed sensed by the sword array, and eighty-one supreme swords swiped together and thought that the phantom would quickly slash away.

As soon as the formation is touched, the most obvious loopholes and shortcomings will be exposed.

Cao Yu saw that under the stone platform of the eighty-one supreme swords, a crystal-like stone shimmered there,

If you didn't urge this killing array, you might not know at all, because when you didn't urge it, the spar would have thought of a normal stone, and there was no difference at all.

Seeing this, Cao Yu smiled and found the root cause, and the medicine was cured!

An unknown knife appeared in his hand, which was brought out in the Tianxuanzi inheritance, although the style was not very good, but it also reached the holy level, but Cao Yu was not used to this kind of weapon.

The style he walks, wide open and close, this dagger is suitable for killers!

"Ding!"

The spar belongs to the spirit stone type of mineral, naturally unable to resist the blow of the saint-level weapon, and the sound shattered, and there was no sword formation without the source of energy, and immediately all the supreme-level swords fell to the ground.

Although these swords can only be used as consumables for Cao Yu, they are also a lot of wealth, and with a wave of his hand, all the swords are stored in the storage ring.

These swords, if they were normal Martial Emperor monks, they would be extremely excited when they saw them, after all, not everyone had that kind of opportunity to get these high-level swords.

Comparisons are odious!

Just like the rich and the poor, they may be dispensable in the eyes of the rich, but for the poor, they are treasures that cannot be obtained in their lifetime.

So a lot of things are relative, and nothing is absolute!

Although Cao Yu is not rich, where did he get it from Lu Liang, and some of the treasures he got before, he is naturally a little rich.

Breaking these formations, an underground passage appears in front of you!

There are many night pearls lit on both sides, and after walking a stick of incense, I finally arrived at the treasure house.

"Shhh

Even though Cao Yu had seen the treasure house of Xuanyue Country, when he saw the treasure house of the Pan family at this moment, he felt that he was really a hillbilly.

Where the eye enters, the spirit stones are piled up into a mountain, and one-third of the entire space is spirit stones, and the spiritual energy of the entire space is more than a hundred times richer than that outside.

Of course, most of them are still low-grade spirit stones, there are many middle-grade spirit stones, and I haven't seen the high-grade spirit stones and the top-grade spirit stones, but there are hundreds of boxes next to the mountain of spirit stones.

Cao Yu stepped forward to open it!

Suddenly, an extremely rich aura came to his face, and Cao Yu took a deep breath, the smell of money!!

It's so comfortable!

Open more than ten in turn, all of them are of the quality above the top grade spirit stones.

Walking further back, there were nearly a hundred silver-painted boxes, with a hint of anticipation in their hearts, and this time the aura impact was stronger.

It actually formed a misted aura, which had evaporated into spiritual liquid, and it was extremely rich!

So many top-grade spirit stones!!

Cao Yu smacked his tongue secretly, according to preliminary estimates, the spirit stones in each box were estimated to be in a thousand pieces.

One hundred boxes, that's 100,000 top-grade spirit stones!

Converted to high-grade spirit stones, that's 10 million!

The medium-grade spirit stone is one billion!!

Cao Yu felt that it was really a wise decision to come to destroy the Pan family.

However, judging from the treasure house of the Pan family, this cruel and unscrupulous family must not know how many people have killed to have these spirit stones.

Although there will be income in serious business, how can there be such a lucrative transaction, in the meantime, there are naturally some unsightly deeds.

The power of the soul quickly unfolded, and he began to put away the spirit stones!

Although the work of collecting money is a bit boring, Cao Yu feels that it is a very happy thing, and he wishes that such a tiring thing would come to him every day!

When he received the last box, he saw a golden box.

Judging from the previous situation, there must be good goods in this kind of box.

Some apprehensively opened, and a substantiated aura rose to the sky.

"This!!"

Cao Yu was directly dumbfounded when he saw the situation inside.

If you look closely, all of them are the same as the spars that were inlaid into the killing array on the outside just now.

How could Cao Yu not know this thing, he was still a little heartbroken when he broke that piece of spirit crystal just now!

After all, it's an absolute good!

One spirit crystal can be exchanged for one hundred top-grade spirit stones!

This thing is a hard currency for the cultivation of the Martial Emperor realm! And it is a good thing that cannot be found, so it is extremely lacking, and as long as the general forces dig out this kind of spirit crystal, they will not take it out and sell it, after all, this is the key to breaking through the Martial Emperor!

Therefore, even if it was a thousand, or even ten thousand, of the best spirit stones, no one was willing to exchange them.

"Rich, rich!"

Cao Yu rubbed his hands excitedly, but his face changed directly in the next second, because a voice sounded in his head.

"Boy, this thing is of great use to me, keep it for me!"

Naturally, it was Xiao Yuan who would speak to him.

"Get out, you big, I haven't covered the heat yet, you're robbing again!"

Although he knew that Xiao Yuan wanted this thing definitely for the Chaos Source Pearl, he still had trouble in his heart, and this good thing could speed up his cultivation a lot.

But when he thinks of the importance of the Chaos Source Bead, Cao Yu will still choose to give it to Xiao Yuan, in the final analysis, he still needs to help himself, and the road ahead is still very long, and he still needs the Chaos Source Bead to give him enough help for a long time.

"You have enough other spirit stones, those garbage are useless to me, only can this thing speed up my recovery!"

What Xiao Yuan said was naturally the scene of the previous thunder in Danta, according to this calculation, the absorption and loss of the thunder tribulation seemed to be a loss!

Cao Yu smacked his mouth, and could only reluctantly agree, but his mouth was not forgiving, and he said angrily: "The next time you need to use the energy of the Chaos Source Bead, you must get my consent."

He has been scared of this pit and has to guard against it!
