Entering the second floor, Ye Mo took a serious look around.

It's just that the books on the second floor of the bookshelf are much less than the first floor, Ye Mo walked over and checked it, they are all medium-grade spiritual skills, so many medium-grade spiritual skills, Ye Mo is also a little surprised by the wealth of the Imperial Academy, so in this way, wouldn't the third or fourth floor have high-grade spiritual skills?

"Demon Knife, you are here first to see if there is anything you need, if you don't have enough spiritual points, wait for me to come back, I'll go up and take a look." Thinking of the high-grade spiritual skills, Ye Mo didn't stay any longer, and directly ascended to the third floor.

"Huh?" Ye Mo exclaimed softly, there was no spiritual skill in the third floor, and a lot of various spiritual objects filled the small room on the third floor.

With a turn of his eyes, Ye Mo looked at a silver long knife in front of him, his footsteps paused slightly, stretched out his palm and moved above the spiritual object, Ye Mo who just wanted to grab the spiritual weapon in front of him, his palm stiffened, and he felt that the fire fairy spirit in his body was actually vibrating strongly...

Ye Mo's pupils shrank slightly, and his gaze swept tightly over the various spiritual objects in front of him.

After a while, Ye Mo's gaze stayed on a fiery red spar next to the spirit weapon.

Ye Mo gently picked up this piece of fiery red spar, and the fire fairy spirit in his body vibrated even more strongly, as if conveying to Ye Mo the meaning that it needed this thing, Ye Mo looked at the introduction of the fiery red spar on the side:

"Flint contains pure fire energy, exchange for spirit points: five hundred points. ”

Ye Mo casually held this flint in his hand, then walked around, and found that there was no item that could attract the immortal spirit in his body, so he continued to go up to the fourth floor.

"Sure enough, the high-grade spiritual skill is in the fourth layer. Ye Mo looked at the three scrolls in front of him that exuded a faint light, and a trace of fiery color flashed in his eyes, Ye Mo himself only cultivated a few low-grade spiritual skills, and there was also a medium-grade spiritual technique, Fire Wind Fist, as for high-grade spiritual skills, he had never seen them.

Ye Mo flipped through the introduction of the high-grade spiritual skill scroll in front of him one by one:

Nine fingers to break the air: one finger can break the flow, and one finger can break the air. Exchange Point: 100,000 Spirit Points. Cultivating the Nine Fingers of Breaking the Sky Requirements...

Sky Shadow Step: Take a photo in the air, and the geese pass without a trace. Exchange Point: 80,000 Spirit Points. Cultivation requirements...

Imperial Sword Technique: High-grade swordsmanship. Exchange Point: 120,000 Spirit Points. Cultivation requirements...

"11,000 spirit points. Looking at the spirit point in the identity jade card, Ye Mo muttered to himself, there is a long way to go.

Back on the second floor, the demon knife at this moment was looking at it with a hot face before a volume of mid-grade spiritual skills, and at this time, seeing Ye Mo coming down, the demon knife put down the spiritual skills in his hand and introduced: "Boss, how is it?

Ye Mo nodded, and said to the demon knife: "Give me your identity jade plate." ”

Glanced at the spirit points in it, there were only ten spirit points, and the spirit points required for a medium-grade spirit skill ranged from five hundred to one thousand, and finally understood what the dean said at the beginning, there was not enough strength, and it was really not easy to obtain a medium-grade spirit skill, so he took his identity jade plate and touched it lightly, turned five thousand spirit points, and returned it to the demon knife.

Although Ye Mo also wanted to cultivate some medium-grade spiritual skills to improve his combat effectiveness, he just thought about it, and the Fire Wind Fist was enough to use it for the time being, so he decided to forget it for the time being, and then directly exchange it for a high-level spiritual skill.

After waiting for a while, seeing that the demon knife was holding a spiritual weapon in his hand at the moment, and holding a scroll tightly in his other hand, Ye Mo turned around and went outside the spirit pavilion, and when the demon knife saw this, he also hurriedly followed.

At the gate of the Spirit Pavilion, Ye Mo registered the flint, turned around five hundred spirit points, and the cold old man who managed the Spirit Pavilion saw this fiery red spar, but glanced at Ye Mo in some surprise, just a kid from the realm of a two-star spirit master, what is the use of this flint? But he didn't say anything, nodded lightly, and signaled that Ye Mo was okay.

"Senior, hello, please help me exchange two thousand plum mid-grade spirit crystals. Ye Mo put away the flint in his hand, and then said to the old man calmly.

"Well, are you sure? Although spirit points can be exchanged for spirit crystals, spirit crystals can definitely not be reversed for spirit points. The old man seemed to feel a little unable to see through the cold young man in front of him.

Ye Mo nodded: "Yes." ”

After putting away the spirit crystal that the old man took out, Ye Mo and the demon knife said that they had something to do and went directly to his cave to find him, and then left.

...

After returning to his cave, Ye Mo cautiously closed the door of the cave.

Ye Mo took out the flint he had just exchanged from the spirit ring, and with a wave of his hand, a gently trembling fire fairy spirit appeared in his palm.

Ye Mo looked at the flint in his other hand, frowned and muttered to himself, "How do you use this thing?" and gently approached the flint to the fire fairy.

Rumble...

The fire fairy slammed into the flint, and from the outside, the fire fairy was rapidly pulling away the fire energy from the flint, and after a minute or two, the fiery red spar turned into a gray-white color full of cracks, and with the evacuation of the fire fairy, with a pop, it shattered and fell to the ground.

At this moment, the volume of the fire fairy spirit has become slightly larger, and the color is more intense. But the most terrifying thing about Ye Mo was that the gray aura wrapped around the fire fairy spirit actually had such a small piece of white.

"With enough flint, the fairy spirit can advance?" Ye Mo's pupils shrank violently, in the fairy plane, the immortal spirit cannot be promoted, and the iron law that can only be replaced has long been integrated into the depths of the soul of every immortal spirit in the immortal plane, but at this time, it seems that it is not so applicable to his own immortal spirit?

Calming down the shock in his heart a little, Ye Mo restrained his mind, took out the spirit crystal he had just exchanged, and prepared to retreat and cultivate well, his realm has not been improved for too long, and the young man doesn't know how long the earth has passed, although he heard his grandfather say that the lower the level of the plane, the slower the flow of time, but he still has a sense of urgency in his heart.

The young man sat cross-legged with his eyes closed, his hands folded, and a strange knot in front of him, breathing steadily and forcefully.

One day...

Two days...

...

In the cave, the young man was naked, his chest was slightly undulating, and his breathing was very rhythmic.

As if sensing the more and more abundant aura in his body, the young man's little face also raised a shallow sense of relaxation.

Tasting the sweetness, the young man did not stop there, his eyes were still closed, the handprints on his fingertips did not move at all, he concentrated and condensed, maintained the best cultivation state, and continued to greedily absorb the gentle energy in the spirit crystal.

The cyan aura, with the young man's breathing, slipped into the young man's body, warming the bones and washing the spiritual veins...

Under the boy's endless demand, a rose spirit crystal was constantly broken after absorbing the aura, and more and more cyan drifted around the boy, and in the end, it faintly covered the boy's naked body.

Practice, slowly spent in the penance of forgetting to sleep and eat, the sky outside the window, from dark to bright, and then gradually darkened, slowly alternating...
