Chapter 1789: Leyline Core Stone

The leyline core stone is not large, only the size of an egg, and the whole body is amber, as if it contains a starry sky, vast and heavy.

Holding it in the hand, there is a faint warm feeling.

Zhang Jian could feel the rich demonic aura inside.

But this is not what pleases Zhang Jian the most.

The Bronze Mountain Mentor comes from the Stone Giants, who are not flesh and blood, but born from the earth.

What they are best at is earth magic, and this leyline core stone is an extremely precious ore in the divine realm.

It contains the power of the earth, and this leyline core stone is more precious than ten superb magic stones.

For Mentor Copper Mountain, this is a precious gem.

For Zhang Jian, this is a key to unlocking the treasure.

And this treasure is his left eye.

That is, the magic eye in the eyes of gods and demons.

In the eyes of Zhang Jian's gods and demons, a large amount of ancient god power and the qi of the first demon were sealed.

However, Zhang Jian himself was unable to open it.

At the beginning, in the Fallen Heaven Demon Country, the wilderness opened a trace for Zhang Jian.

It is equivalent to opening a gap in the door, allowing the Qi of the First Demon within it to flow out.

But that's all, since Huang left, Zhang Jian's magic eye was closed again and could not be opened again.

And just now, when Mentor Tongshan took out the leyline core stone, Zhang Jian felt his demon eye seal, and there was a trace of loosening.

It was for this reason that Zhang Jian decided to accept this leyline core stone.

"Brother Gu Yuan, they have already left!"

Tutor Dingqiu entered the room and opened his mouth to tell Zhang Jian.

"Well, okay, I need to retreat, you help me protect it, don't let outsiders in!"

Zhang Jian nodded, but he was already a little impatient in his heart, and immediately spoke directly.

"Yes!"

Although Tutor Dingqiu was puzzled, he didn't ask too much, turned around and left the room.

"I don't know if this leyline core stone really opens the Demon Eye, if it can be opened, I will be able to directly absorb the Qi of the First Demon in the seal!"

Zhang Jianshen's thoughts spread out, covering the entire room.

However, he did not end there, but the demonic energy surged, and began to carve the magic array.

Throughout the room, he carved nine magic arrays at once, and not all of these nine magic arrays were the strongest ninth-order magic arrays.

There are different levels within it, but the performance of the magic array complements each other, making it even more powerful.

This is a protective type magic combination array, in order to avoid being disturbed by others during the cultivation period.

After doing all this, Zhang Jian sat cross-legged, holding the earth vein core stone with both hands.

"Hopefully it will work!"

At this moment, Zhang Jian felt a little nervous in his heart.

He took a deep breath and then activated the energy within the leyline core stone.

The earth vein core stone contains the majestic power of the earth, and with a little attraction, Zhang Jian can feel the majestic demonic energy like the boundless ocean.

This demonic aura is very heavy, ancient, and desolate.

It seems to have existed for hundreds of millions of years, and I don't know how long it has been accumulating.

Zhang Jian's body was a little unbearable, his body shook, and he almost fell to the ground.

But soon he stabilized, guiding this majestic and heavy demonic qi towards his left demonic eye.

Swish!

Zhang Jian's left eye instantly turned black, like a black hole, but there was a seal on it, this was the seal of the Nine Rings Heavenly Venerable, and it was not something that Zhang Jian could easily break.

Last time, it was Ara, with his powerful strength, who forcibly opened a gap.

But at this time, the demonic energy of the leyline core stone slowly submerged into the demon eye.

Suddenly, in Zhang Jian's magic eye, an extra pattern suddenly appeared.

It's like a mountain, and it's like a word.

This is a primitive sermon.

A "ground" word.

As tall as a mountain, as thick as the earth, with an unprecedented momentum, it was slowly suppressed.

Suddenly, Zhang Jian could clearly feel that there seemed to be a crack in his left eye slowly emerging.

This crack slowly expands, and there is no pain of forceful retreat, only the comfort of slowly opening.

The familiar Qi of the First Demon, like a clear spring, flowed out of the demon's eyes, flowed into Zhang Jian's body, and scattered in Zhang Jian's limbs.

Even his divine soul, even his demonic appearance, seemed to be nourished at this moment.

"It works!"

Zhang Jian's eyes showed a look of surprise, his guess came true, this leyline core stone was indeed able to open the seal of the Demon Eye, allowing himself to absorb the Qi of the First Demon.

"My realm has been stagnant for a long time, and this time, I borrowed the qi of the first demon and broke through to the eightfold realm of the Great Demon God in one go. ”

Zhang Jian knew in his heart that he was invited by the Duke of the Bone Buddha to become the ace mentor of the Magic Sacred Academy, so he would definitely attract the attention of other mentors, and even provoke.

You must know that the mentors in the Magic Sacred Academy are not easy to mess with, and there are many powerhouses in the Demon King Realm.

Therefore, Zhang Jian must ensure that his strength becomes stronger, so that he can be able to cope with the many risks and challenges that are coming.

"Come on, Eighth!"

Zhang Jian closed his eyes again, guiding the demonic qi in his body to comprehend the new avenue and make a breakthrough.

......

Zhang Jian was in retreat in the room, and the academy battle was completely over, and the tutors from the major academies also left one after another.

However, Mentor Dingqiu didn't leave, because he promised Zhang Jian that he would protect him, so he planned to wait for Zhang Jian to leave after he was out.

And Qianling, Bai Ze, and Tong'an have already been arranged to enroll, and after going through some procedures, they officially became a student of the Magic Academy.

Of course, they are still only the lowest level of iron medal students.

As for the Devouring Heavenly God and Miao Heavenly God, they also lived in the original Zhang Jian's room for the time being, they knew that their identity was special, and the matter of the troll auction that day would also bring some trouble to Zhang Jian.

Therefore, they did not choose to go out, and they all stayed in the room honestly to recuperate.

"It's been the third day of retreat, and the Duke of the Bone Buddha said that he would let Mentor Gu Yuan go to him in three days!"

Outside Zhang Jian's retreat room, Mentor Dingqiu looked anxious.

He was anxious about Zhang Jian.

On that day, the Duke of the Bone Buddha asked Zhang Jian to go to the Necromantic Cave to find him in three days, and today was the appointed day.

But Zhang Jian has not yet shown signs of being out of the customs, which has to make Mentor Dingqiu feel anxious.

After all, this is the Duke of the Bone Buddha, he called Zhang Jian to go, there must be a good thing, if he misses it, it will be a pity.

However, Mentor Dingqiu tried to call out to Zhang Jian, but he was blocked by the magic array, and he didn't dare to force in, so he had to stand outside the door anxiously.

"Mentor Chu Fan, come to visit the ace mentor!"

Just when Mentor Dingqiu was full of anxiety, a shout with a hint of provocation suddenly sounded.

This voice was not disguised in the slightest, it was directly abrupt, and many students in the Holy Courtyard heard it.

For a time, everyone knew.

The mentor in the Holy Courtyard finally couldn't sit still, and deliberately came to trouble Zhang Jian at this time today!
