In one month, Yang Yi gained a lot, not only was he able to refine the power array, but even the two-star petrified array Yang Yi also found the law of material dissolution, it can be said that it only took Yang Yi a month to transfer his strength from a two-star or three-star magic circle master, which is an absolutely impossible fact in the eyes of others.

But Yang Yi did it, and he did it.

But Yang Yi, who achieved all this, did not pay a price, not only did the few demon beast skins left after breaking out of the Demon Burial Forest have been exhausted, but he also got those high-grade magic crystals by accident, and most of the materials were purchased, and Yang Yi saw that there were no materials to refine.

As a mentor, Yang Yi still has his own fixed salary, four high-grade magic crystals per month, but these high-grade magic crystals are not enough for him to refine twenty milliliters of power array solution.

What to do?

In desperation, Yang Yi only woke up from the crazy refining and began to look for a solution.

Selling your own circle solution?

Yang Yi immediately thought of the method he used to exchange for high-grade magic crystals.

But Yang Yi came to Falling Cloud City for the first time, and he still knew very little about Falling Cloud City, and Yang Yi didn't know at all whether his magic circle and magic circle solution could be sold for more than the price of Red Stone Town in such a place.

As soon as he walked out of the library, Yang Yi saw a black shadow flashing into the back of the library, and out of curiosity, Yang Yi immediately followed.

Dai Zhiguo?

Turning the corner, Yang Yi immediately recognized that the person in front of him was Dai Zhiguo, who he hadn't seen for a month.

After a month of cultivation, Dai Zhiguo has fully recovered, and looking at the way he pinched his feet lightly, Yang Yi sensitively felt that something was wrong, and Yang Yi even felt that these would be related to him.

The size of the demitheological academy was completely beyond Yang Yi's imagination, and for more than ten minutes, Dai Zhiguo still did not reach his destination, and Yang Yi, who was quietly following behind, already felt out of breath at this time.

Finally, nearly half an hour later, Dai Zhiguo came to a separate courtyard, and after vigilantly observing the surroundings, Dai Zhiguo immediately entered the courtyard and disappeared.

Yang Yi didn't think about it, and followed Dai Zhiguo's figure and rushed towards the courtyard.

Bang!

A huge force came, and Yang Yi was bounced out of his breath, and a stream of heat came from his nose.

At the same time, in front of the inconspicuous courtyard, a translucent protective shield appeared, and waves of ripples rippled away, until the ripples disappeared, and the shield disappeared immediately.

Eternal Guardian!

After a month in the library, Yang Yi's insight was not the same as before, and as soon as he saw this shield, Yang Yi immediately called out his name.

Sixth-order magic circle, a magic circle that only demigod realm circle masters can use,

Connected with everything that he had just entered the demigod academy, Yang Yi immediately knew who the owner of this inconspicuous courtyard was.

Eternal Guardian is a kind of defensive magic circle, once used, unless it is forcibly destroyed, or knows the spell of the magic circle in and out, everything inside will be a permanent mystery, and Yang Yi can be sure that on the outside, the ordinary courtyard is just an illusion, it is a fantasy reflected by the eternal guardian, and the real courtyard will definitely not look like this.

Ay!

With a long sigh, Yang Yi turned around and wanted to leave, now it's not just him, it's Vice Dean Sun De who is here, and it's impossible to easily crack the Eternal Guardian, for this guardian array that can even block the sound, Yang Yi has nothing to do.

"Wait a minute, if you help me take out a few Star Stones, I can find a way to get you in. Suddenly, the old man who had been silent for nearly two months suddenly appeared, and that confident voice suddenly appeared in Yang Yi's mind.

"What are you doing these days?" Hearing the voice of the old man of the machine spirit, Yang Yi was a little surprised, although Sun De could not easily crack the eternal guard, but Yang Yi didn't know if the erudite old man of the machine spirit could crack it, or that Yang Yi had more expectations for the old man of the machine spirit.

"You just said there's a way to crack this Eternal Guardian and let me in?"

"Crack the Eternal Guardian, if I fully recover, maybe I can crack it without alerting the circle master who released the circle, now, I can't do anything, and if you don't hide as soon as possible, I'm afraid that a few of the ancient warriors in the room will find you." "The old man is always unhurried, even if Yang Yi is about to be discovered, he is still slow and methodical.

Using his fastest speed, Yang Yi immediately rushed out, and in a few ups and downs, Yang Yi had already come to the back of a private house, and the house in the distance was only the size of a fingernail in his eyes.

For the reminder of the old man of the machine spirit, Yang Yi has never doubted it.

"Well, the reaction is very fast, and the speed is also very fast, this is the escape. Before he could catch his breath, Yang Yi heard the old man's evaluation of him,

"Are you wasting your precious time just to tease me?" Yang Yi was a little angry, he didn't know how long it would take Dai Zhiguo, if he waited until the old man of the machine spirit thought of a way, but Dai Zhiguo came out, then everything was meaningless, as for the old man of the machine spirit said to help him take out the star stone, Yang Yi would not be a thief for the old man of the machine spirit.

"Don't worry, the courtyard inside is very big, that Dai Zhiguo hasn't found the owner yet, and it's useless for you to go in now. ”

"How do you know?" Yang Yi asked in surprise, knowing that the Eternal Guardian would even be blocked by the Divine Yuan, Yang Yi really couldn't imagine what kind of method the old man could use to detect the things inside.

"Stupid, everything has weaknesses, otherwise wouldn't it be impossible to crack just an eternal guardian?" Of course, the old man of the machine spirit would not let go of this opportunity to teach Yang Yi a lesson, and before Yang Yi could refute, the old man of the machine spirit continued: "Wrap the divine element around your whole body and force it in,"

Hearing the words of the old man, Yang Yi did not hesitate, Shen Yuan instantly sent out, and the silk threads that only he saw tightly wrapped the whole body, and after a few ups and downs, Yang Yi came to the front of the courtyard again, but Yang Yi did not hesitate this time, and rushed in directly at the fastest speed.

Kiss!

Just like a stone thrown into a waterhole, Yang Yi's whole person disappeared in front of the courtyard in an instant, and only the ripples of the eternal guardian proved that Yang Yi had just existed.

There is a hole in the inconspicuous courtyard on the surface, a building that is no less than the suzerain's mansion stands impressively, the gold is splendid, the carved beams and painted pillars are no longer enough to describe the luxury and exquisiteness of this courtyard, here is probably the most beautiful and magnificent building that Yang Yi has seen.

"Dai Zhiguo, has Yang Yi been to the sixth floor of the library, has he found our things?" Tutor Dai Baode, who was sitting high on a throne carved of amethyst, in the middle of a large hall, asked with a serious face.

In the middle of the hall, Dai Zhiguo completely lost his usual domineering, like a servant, standing there with his head bowed, waiting for his master's orders.

Hearing Mentor Dai Baode's inquiry, Dai Zhiguo hurriedly replied, "Yang Yi only looked for those magic circle scrolls below the third layer, and he didn't even go to the fourth layer. ”

"Well, you have to watch him carefully, don't let him go to the sixth floor. After a pause, Mentor Dai Baode commanded.

"Uncle, are those things in a different place? With Yang Yi's learning speed, I'm afraid it won't take me more than a few months for him to enter the sixth floor, and I won't be able to stop him at that time. Dai Zhiguo's face was worried.

"Don't be afraid, we recently had an exchange with the Thorn Hao Sect's Thorn Hao Academy, our academy is going to send a mentor to lead a few students to the Thorn Hao Sect, you also know, the Thorn Hao Sect and our Tiandan Sect are mortal enemies, the so-called academy exchange is nothing more than to take this opportunity to kill some of our academy's elites, in order to achieve the purpose of attacking our academy, but since we can't refuse, I think it's ......" said Dai Baode sinisterly laughed.

Dai Zhiguo also laughed, although Yang Yi has been busy refining the magic circle and learning the knowledge of the magic circle, but in Dai Zhiguo's opinion, Yang Yi is his biggest enemy, and he is also the person who once insulted him, and that kind of shame can only be compensated by Yang Yi with his life.

Suddenly, Dai Zhiguo seemed to remember something, and said cautiously: "But that old guy Sun De seems to appreciate Yang Yi very much, and I'm afraid that he will stop him when the time comes." ”

"Sun De, hehe, I'm in charge of outside affairs, and even Sun De can't change what I decide," Dai Baode's face was full of anger at the mention of Sun De, but Dai Baode was still very confident in his status in the Demigod Academy.

"You go back, pay attention to our stuff, I don't want anything to happen these days. Dai Baode waved his hand and turned to walk inside.

"These vicious guys," Yang Yi, who had been hiding outside the main hall, was full of anger, if it wasn't for the old man who had been reminding him, Yang Yi would have rushed in a long time ago.

"Where is the place where this old guy put the materials?" Yang Yi also knew that in a head-on confrontation, he was definitely not Mentor Dai Baode's opponent, and if Mentor Dai Baode discovered his current location, Dai Baode could directly kill him without any academy communication, and in front of a demigod realm magic circle master, Yang Yi had no chance to escape at all.

Originally, everything was impossible, but Yang Yi had an old man with a machine spirit, and the erudition of the old man made Yang Yi enter Dai Baode's courtyard as if he were in a no-man's land.

"I felt the fluctuation of the extremely strong circle in the walls of the front side hall, and I believed where all the materials and important things of Dai Baode were. "The old man is not only erudite, but also more powerful in the exploration of various powerful materials and energies, and from a long distance, the old man can tell the name and attributes of this material by virtue of his perception of power.

According to the instructions of the old man, Yang Yi came all the way to a snow-white wall unimpeded.

Secret room, secret door, a series of nouns appeared in Yang Yi's mind, and without the command of the old man, Yang Yi began to look around to find a way to open the secret room.
