Han Feng put away these thoughts, waved his hand and shot out a flame, burning the flesh and blood of the doppelganger of the Seven Princesses of the Demon Clan into ashes, and there was nothing left.

Then, he took out her storage ring, injected soul power, and refined it smoothly, containing many Demon Realm Crystals, containing a large amount of Demon Realm spiritual power.

In addition, there were various elixirs, but most of them were from the Demon Realm, and he didn't dare to take them.

Of course, all kinds of minerals, all kinds of weapons and some miscellaneous things unique to the demon world are also among them, and even a half-step spirit treasure level weapon is still there, you can imagine the wealth of this seventh princess, after all, this body is just a doppelganger of hers, with such wealth, if the real body comes, how can it not dominate the heavens and the earth.

There are so many things, and those Demon Realm Crystals are of some use to Han Feng.

He sorted them away, and then took out the various pills and took them to recover his state.

At the same time, he looked at the surrounding Biluo Nine Shadow Array, silently analyzed its structure, and began to think of a way to crack it.

As a ten-rank heavenly rune master, he gradually saw some clues, but he was still unsure, after all, he hadn't released his soul power to investigate.

With a general idea in mind, he stopped observing and devoted himself to the recovery of his state.

Time passed quickly, and most of the hour passed in the blink of an eye.

Han Feng also recovered seventy-seven eighty-eight, and immediately released a rolling soul power, enveloping all directions, silently probing.

......

Time passed in a flash, and in an instant, three days and three nights passed.

Han Feng rubbed his eyes, for a period of time, he had been struggling to comprehend the Biluo Nine Shadows Array, trying to find a way to crack it, but this formation was not big, but it contained a lot of things, and all kinds of runes were cyclically nested, complicated and intertwined, which was definitely beyond the ability of ordinary runes to penetrate.

He watched it for three days, and only came up with three or four methods, and he also practiced them seriously, but he couldn't successfully lift it, but he was hurt by the hidden mystery of this formation, making him dizzy, if it weren't for his thick foundation, I am afraid that he would be more seriously injured.

Of course, he didn't do it in vain these days, and gradually found out some veins, and he could follow the vine and slowly sort out the rune structure of this formation.

He came up with a method, and after silently practicing it in his heart, he put it into use, but it still didn't work, and he was once again shocked back by the secret power of the Biluo Nine Shadow Array, so that his soul power line collapsed, but fortunately he cut off the connection in time and did not be shocked by it.

Han Feng took a deep breath, stabilized his mind, and continued to study this formation without the slightest discouragement.

Time flies, and before I know it, another seven days and seven nights have passed.

Han Feng forgot to sleep and eat, and devoted himself to cracking the Biluo Nine Shadows Array, slowly sorting out a clue, basically mastering the structure of this formation, he used various methods, but he never succeeded.

He is reflecting, constantly summing up experience, arching the past little by little, and there will always be a breakthrough one day.

Although he has not yet succeeded, in the process of cracking it, his ability to solve the path of the formation has unconsciously improved a lot, and many problems have been bypassed, and he has been able to draw inferences from one another and solve the existing problems one by one.

It's just that the internal structure of the Biluo Nine Shadows Array is complex and unpredictable, making people incomprehensible, and Han Feng has to find its essential law in the complex changes.

This not only requires him to have a strong soul power cultivation, but he also has a profound formation realm, and more importantly, understanding, otherwise it will be useless to have the first two items.

Cracking the formation is ten times more difficult than building the formation, just because Han Feng doesn't even know the formation diagram of the Biluo Nine Shadows Formation, let alone understand the methods and ideas of the builder.

What's more, the constructor of this Biluo Nine Shadows Array is also a peerless master of the Demon Clan, and his formation method must be superb, and he doesn't know how much stronger than him.

In other words, he is now challenging a formation master, and through this Biluo Nine Shadows Array, it can be said that there is almost no possibility of success if he fights with the other party across time and space.

Han Feng struggled to figure it out, but after another five or six days, he couldn't find a way out of his way and couldn't crack this formation.

Instead of seeking the help of the remnant talisman, he continued to study, he felt that this was an alternative chance, and once he successfully cracked it, his formation path would be greatly improved.

He thought hard, continued to sort out the experience he had gained before, and came up with various methods to confirm his judgment from all aspects, trying to decipher the secret of this formation.

The time passed quietly, and soon more than ten days passed.

Han Feng's brows furrowed, the more he delved into it, the more he didn't understand, as if the information he had obtained before was only a scale and a half claw of this Biluo Nine Shadow Array, and he didn't see its core at all.

Perhaps, this is that the more you understand, the more things you don't understand!

He was not discouraged, and his mentality relaxed a lot, and he no longer insisted on cracking this formation, he only thought that he could absorb knowledge from this Biluo Nine Shadows Formation and improve his own formation.

The change in mentality made him understand a lot, and gradually became handy, and various problems were solved excellently, which in turn enhanced his ability to crack the formation.

Time flies, and the four days pass by.

Han Feng's eyebrows were stretched, and his eyes were shining, as if he had a lot of enlightenment.

If he was facing an ocean before, now he sees a lake.

It's not that the rune path of the Biluo Nine Shadows Array has become simpler, but that his strength has improved, and he can see wider and farther, and as a result, the rune path world of the Biluo Nine Shadows Array has become smaller.

Han Feng gradually touched the core area of the Biluo Nine Shadows Array, and he was about to have a feeling of seeing the moon through the clouds, which made him feel comfortable and wonderful.

Once this formation is successfully cracked, then all the mysteries of this formation will be known to him, and over time, it will not be difficult to construct it on his own.

However, just when he was about to succeed, this formation suddenly shook, and a series of secret powers poured out from the inside out, deconstructing themselves, and the huge formation Great Xia collapsed and came to naught.

The state that manifested itself was that the light curtains in all directions suddenly flashed a series of turquoise lights, which quickly dimmed and dissipated.

Han Feng looked at the bare stone wall, a little speechless, and thought about it silently, he could only accept this fact.

It's right to think about it, this Biluo Nine Shadows Array is just an imitation after all, encapsulated in a piece of jade pendant, the energy is naturally limited, it is impossible to last forever, and it can last for about a month, which is already very remarkable.

He was a little regretful, he originally wanted to absorb more nutrients from this formation and improve his formation, but as soon as he reached the key place, this formation disappeared, making his plan fall through.
