According to Wu Aotian's thoughts, this old man was already an ancient, and secondly, if he really inherited his phantom array and his other wealth, then he could really be regarded as his master.

Although in the previous life, the inheritance of various skills and abilities is no longer like ancient times or this world, but the concept of respecting teachers is still deeply rooted in the hearts of the people, so Wu Aotian does not mind kowtowing to this old man a few times and worshipping him as a teacher.

However, just after Wu Aotian's three heads were finished, strange things happened again.

The door that had been opened not far behind the old man suddenly closed quickly, and just when Wu Aotian was strange, a crack suddenly opened on the wall on the other side, and another door slowly slid open.

Wu Aotian's eyes widened, looking at this strange change, but he suddenly realized in his heart, I am afraid that this change has something to do with the three rings of his knock.

"Apprentice, I'm very happy, you can honestly kowtow to me and worship me as a teacher in this situation, no matter who you are or what kind of personality you are, but at least it shows that you still respect the teacher in your heart, no matter how bad it is, it can't be bad, and I am very happy to be a teacher. ”

"The door that I opened just now, there are not only advantageous phantom arrays inside, but also some other attack formations, even if you can pass through, the things inside are not of much value, and the real good things are hidden in the door that was opened just now. ”

"Don't blame me for this final test, now you can go and get the real wealth left to you by the master, and, in addition to these riches, in the woods behind the north of this ancient city, there is another gift left by the master, don't forget to go there, but before you go, you must complete the production of the Ecstasy Spirit Array spirit weapon. ”

"The last thing is to transfer my body to the small room inside before you leave, this city is my painstaking creation, let me and her always sleep here, and stay together. ”

At this time, there was already a little more emotion in the voice of this Yelu Sect, as if he was pointing out to his disciple Dun Dun on his deathbed, and there was a bit of satisfaction in his voice.

Wu Aotian admired this dead old man in his heart, and whispered respectfully: "From today on, I, Wu Aotian, am your old disciple, and I will definitely continue to carry forward the inheritance of the phantom array left by your old man!"

After respectfully saluting the old man again, Wu Aotian took a step and walked into the door that had just opened.

After entering this door, he found that there was a cave inside, and it was divided into many small rooms, Wu Aotian pushed open the door of each small room, and first briefly browsed it, just like this, Wu Aotian's heart couldn't help beating violently with excitement.

The wealth in these rooms can only be described as amazing, if it has to be a little deeper, it is super amazing.

A large amount of Heavenly Spirit Pill and a small amount of Pure Spirit Pill......

miscellaneous and miscellaneous various other elixirs......

Quite a few high-level magic crystals......

There are a lot of various spiritual weapons, or spiritual weapons with some special functions or even formations......

Wu Aotian seemed to have discovered a treasure trove, but when he finished browsing the two rooms that Yelu Sect had said that contained the things of the Dan Fang and the Phantom Array, Wu Aotian knew that what happened before was nothing at all.

The room with the Dan Fang was very empty, and there were not many Dan Fang, there were seventeen in total, but when Wu Aotian looked at a few of them, he understood the value of these Dan Fang.

The pills recorded on these pills are all pills that can help people increase their cultivation speed a lot, and there are even elixirs that can directly improve the stage of ascension, and because most of the objects used by these pills are above the heavenly spirit, if any of these pills are revealed to the world, I am afraid that it will lead to a bloody battle.

These pills can't be measured by value at all, but in the same way, the raw materials involved in these pills are also extremely precious, if you want to refine successfully, not to mention the high requirements for alchemists, I'm afraid it will be very difficult to find these elixirs alone.

It's just that with these Danfangs, there will always be a day when they will come in handy.

In the room where the phantom array is stored, it is more cluttered, there are all kinds of materials for making the phantom array, as well as books about the phantom array, some phantom array production methods, etc., there are many things.

In a small room at the end, Wu Aotian saw thirteen small black swords neatly inserted on the ground.

This is also the weapon of Yelu Sect in the past, the spiritual product is a spiritual weapon heart sword.

Looking at these thirteen small swords, Wu Aotian sighed again in his heart, could it be that he really had a relationship with this kind of spiritual weapon, before his attack spiritual weapon was the Seven Killing Sword, but now he encountered these thirteen heart swords!

The Seven Killing Swords are naturally inferior to these thirteen heart swords, no matter how good the mortal spirit weapon is, it is always a mortal product, and the spirit product spirit weapon already has the ability to be psychic, and can change the size at will, and the power is not comparable to the ordinary spirit weapon at all.

Wu Aotian also found a jet-black void ring among all the objects, Wu Aotian put the ring on his finger, and put some unimportant things in the void ring, but all the important things, Wu Aotian still put them in the Eight Desolations Gathering Spirit Ding, where else is safer than the Eight Desolations Giant Spirit Ding, unless Wu Aotian is dead, no one can take it away.

After storing all the things, Wu Aotian did not leave in a hurry, but began to learn the knowledge of the phantom array and how to make the phantom array in this ancient castle, after all, Yeluzong's last words mentioned that he should go to the woods at the back of the city, but before he went, he had to complete the spirit weapon of the Ecstasy Spirit Array.

After learning about the phantom array, Wu Aotian was pleasantly surprised, because all he encountered before were dead phantom arrays, that is to say, the formation was established in a fixed position, and if others did not enter, then they would not be able to attack others, but in these books, Wu Aotian learned about a living phantom array, that is, the phantom array spirit weapon.

The phantom array spirit weapon is much more difficult than the dead phantom array production, but among the many objects left by Yeluzong, there are also many spirit weapons used to make the phantom array, these spirit weapons are like a blank piece of paper, and Wu Aotian needs to store the phantom array production in this spirit weapon, once completed, as long as you take out the phantom array spirit weapon, input the spiritual energy, and urge the phantom array, the phantom array will run immediately, as for the enveloping range of the phantom array, it depends on the type of the phantom array, as well as the amount of aura infused by the user.

Wu Aotian was made an immortal genius in his previous life, that is because he learned everything very quickly, cultivated everything very quickly, and had super comprehension and ability, although before this, he had not been exposed to any phantom array, but Yelu Sect obviously also took this problem into account, and the books stored were all gradual, so that Wu Aotian read all the way and did not feel the slightest jerky.

Wu Aotian stayed for another three months, and in the three months, Wu Aotian spent all his time studying the production of the phantom array spirit weapon except for sleeping, and constantly became familiar with the various phantom arrays left by Yelu Sect, these phantom arrays are different, the target objects are also different, and the number of opponents is also different, after three months, Wu Aotian scrapped several blank phantom array spirit weapons, and finally succeeded in making the first phantom array spirit weapon.

The formation stored in this phantom array is the Ecstasy Soul Punishment Array that Wu Aotian passed before, but because Wu Aotian's way of destroying the Ecstasy Soul Killing Array is very special, so he himself has no way to understand how powerful this Ecstasy Soul Killing Array is, and he can only estimate from the description of the formation that the power of this formation is quite large, once people enter it, they will encounter all kinds of attacks, these attacks may be extraterrestrial meteorites, or landslides and earth cracks, or they may be powerful magical beasts, or even powerful spiritual cultivators, this formation is mainly trapped, the attack power is not very high, and people who are not strong enter this phantom array, they will be trapped and die in it。

And once the enemy is trapped in the Ecstasy Soul Punishment Array, he will fall into a boundless illusion, and the person who controls the Ecstasy Soul Punishment Array who fights against him naturally wants to kill the other party, so it is very easy.

Of course, the phantom array is not unbreakable, once the opponent's strength exceeds the spiritual cultivators who support the phantom array too much, it is convenient to break the aura of the phantom array and tear the phantom array, and the higher the strength of the spiritual cultivator, the higher the spiritual power, the higher the resistance to the phantom array, and even some special methods, it is possible to directly tear the phantom array.

After completing the refining of the Ecstasy Spirit Array, Wu Aotian breathed a long sigh of relief, and spent a while refining all the thirteen heart swords with blood, thanks to the fact that Yelu Sect had erased the blood mark on it before storing it, otherwise, with Wu Aotian's strength, it would not be possible to erase the mark and re-refine the blood.

After all this was done, Wu Aotian had been in this ancient castle for about half a year, although Wu Aotian had not spent time cultivating in this half year, but the miraculous effect of the Eight Desolations Gathering Spirit Ding had made Wu Aotian's strength still swish and soar, and at this time, Wu Aotian was only one line away from the high-level spirit master, as long as he cultivated for a period of time, he would definitely be able to make another breakthrough.

Wu Aotian inspected all the rooms again, and after confirming that nothing was missing, Wu Aotian came to Yeluzong's corpse again, and after a respectful salute, according to what Yeluzong said, he gently picked up Yeluzong's corpse, and only then did he pick it up, Wu Aotian saw that there was a groove under the position where Yeluzong was sitting, and there were three black things in it.

Wu Aotian took a closer look, and a cold sweat suddenly broke out in his heart, that black thing turned out to be three Demon Crystal Divine Thunder, and it was a very high-level kind!

Looking at this Demon Crystal Divine Thunder, Wu Aotian still couldn't help admiring Yelu Zong's scheming, this Demon Crystal Divine Thunder is obviously to prevent someone from destroying his body, if someone destroys his body, this Demon Crystal Divine Thunder will obviously burst open, in this closed room, the power of the three Demon Crystal Divine Thunder, I'm afraid no one will be able to leave alive at all.

After carefully placing Yeluzong's body in the small room he said, and sealing the small room permanently, Wu Aotian returned to the hall, carefully put away the three magic crystal divine thunder, and looked back at the place where he had stayed for half a year, and then quietly left this ancient castle and headed north, where there was the last gift that Yeluzong said he left for Wu Aotian.
