As he learned about spirituality, Yan Xu felt more and more that he had underestimated the cultivation system of this world.

At first, Yan Xu only thought that spiritual cultivation was a mage who relied on natal spirits to cast spells, and it was nothing remarkable, but with Lan Yu's narration, this profession slowly revealed its complex and profound side, so that Yan Xu, who has ontological memory, put away his contempt and didn't dare to mess around at will, after all, if something goes wrong with his practice, even if his talent is high, it will be in vain, and the way back is so easy to walk.

"Do you know why it is called natal spirit, because this is the root of spirituality, the life of spirituality, if the spirit is well raised, it is not the day when the lower spirit does not turn over, if it is neglected, it is the day when the upper spirit will also decline. Lan Yu said so seriously to Yan Xu for the first time.

There is no shortage of geniuses in this world, after all, as long as there is a good natal spirit, plus similar cultivation techniques, the strength of spiritual cultivation will grow rapidly, and often break into a great reputation when they are young, but such a genius, when they are young, their strength is already the peak of their lives, and it won't take long for them to disappear among the crowd, so after knowing that his disciple is not an ordinary genius, Lan Yu's cultivation of Yan Xu's heart has become a little more, at least so that he will not become a so-called genius who only relies on talent to eat.

After hearing the master's admonition, after knowing that the natal spirit was the foundation, Yan Xu put away his superfluous thoughts and raised his soul with peace of mind.

However, Lan Yu felt that words alone were not enough, so he took Yan Xu to the fragments of the resentful spirit realm again and continued to fight monsters and level up.

Ghost bones are very similar to resentful spirits, in fact, ghost bones are evolved from resentful spirits.

Some resentful spirits that have accumulated enough resentment will choose to attach themselves to the white bones and refine the white bones as their own bodies, so Yan Xu saw a pair of white bones supported in the bodies of several translucent resentful spirits, and they just floated in mid-air and flew towards him.

After having white bones, the attack of the evolved resentful spirit not only has the ability to consume the opponent's physical strength, but also has physical damage, although it is not very powerful, but with the resentment of the resentful spirit, once it is injured, it will be very troublesome, and if it is replaced by ordinary people, even if it does not die, it will be seriously ill, so the strength of the ghost bone should be above the resentful spirit, and it is classified as a lower grade, and the general new disciple really can't beat a ghost bone.

Even if Yan Xu came for the first time, he would feel very troublesome in the face of such an opponent, but for Yan Xu, who had already practiced the first type of cold, frost, and ice in the Cambrian three styles, it was just a little troublesome.

The Cambrian Three Styles is a spiritual skill created by Lan Yu, and it is also with this spiritual skill that she will be made an exception to be named an elder before the age of thirty, as her closed disciple, Yan Xu is naturally able to teach this spiritual skill.

However, this is a top-grade spiritual skill, even with Yan Xu's top-grade natal spirit, at least it needs to reach the realm of the imperial spirit to learn, but who called Yan Xu to cheat, and accidentally initially refined the cold water sword, so he has the basis for cultivating this spiritual skill.

Transporting the spirit technique, the cold water sword was suddenly shrouded in a layer of cold mist, and it was obvious that the first type of cold qi Yan Xu had already comprehended to a considerable level.

Yan Xu stabbed with his sword, and a white mist sword qi stabbed a ghost bone like an arrow from the string, and suddenly the gray and black ghost bones turned white by three points, and the movements also slowed down by three points, just a few sword qi, and these ghost bones turned into slow moving balloons.

Yan Xu was already agile, and he naturally immediately gained the upper hand against the ghost bones that were slow to enter the body, even if the ghost bones were higher than the resentful spirits in terms of attack and defense, it was useless, and they were dismantled by Yan Xu in three or two strokes, and a bone was dropped.

Picking up the palm-sized bone on the ground, Yan Xu couldn't recognize what part of the bone it was, but when he touched it, he felt that the bone was a little abnormally cold, obviously containing resentment.

This thing is harmful to people, but it is one of the materials that can be used for spiritual cultivation, if it is the spiritual cultivation of the ghost spirit department, it can be used directly, and if the spiritual cultivation of other departments wants to use it, it must wash away the resentment and then use the spiritual energy to refine, which requires a lot of effort, so Yan Xu only has the effect of the trial here, and there are no other benefits.

"Fight a few more ghost bones, and then I'll take you deeper. "Obviously, I am very satisfied with Yan Xu's strength improvement, but I can't do it if I can't play the effect of the trial, so Lan Yu decided to let Yan Xu get used to it first, and then take him to the depths, anyway, she is not afraid of any danger if she follows her.

When Yan Xu destroyed a few ghost bones again, Lan Yu took him further into the place where the bones were buried.

The first half of this fragment of the resentful spirit realm is some resentful spirits that do not have much lethality, and it is a place for new beginner disciples to adapt, but the burial place in the second half is different, and every year new disciples die because of this.

Since it is called the place where bones are buried, there are naturally bones of various creatures everywhere, and I don't know how they came about, so the appearance of ghost bones is not limited to human form, and there are many beast-shaped ghost bones, which are called ghost bone beasts, which means beast-shaped ghost bones.

The ghost bone beast is obviously more powerful, after all, some huge beast bones are thicker and bulkier, and only more powerful resentful spirits can refine such bones, so it is more difficult to deal with, even Yan Xu does not dare to be careless, he must maintain his flexible advantages, and cannot be hard-connected, but in this way, the consumption of physical strength is greater.

Especially when the ghost bone bird appeared, Yan Xu became very embarrassed, and from time to time he needed to rely on rolling close to the ground to avoid the ghost bone bird's flutter.

"That's all for today. With a wave of Lan Yu's hand, dozens of ice feathers appeared in the air, and all the ghost bone beasts attracted by the sound of the fight easily turned into ice slag, which showed that Lan Yu's name as an elder was not in vain.

"Do you know your shortcomings?" Lan Yu said lightly as he came to Yan Xu with his hands behind his back.

"Got it. Yan Xu panted and propped his knees, but quickly straightened up and began to adjust his breathing.

"Very good, then do you know how to change it?" Lan Yu knew that Yan Xu would not pretend not to understand, and understood that he really knew his shortcomings, so he asked again.

"It's hard. Yan Xu's breathing calmed down a lot, but he shook his head at Lan Yu's question.

The previous battles exposed a lot of shortcomings, lack of powerful attack means, very weak for opponents who can fly, and lack of sufficient defensive capabilities, the only advantage is that they are flexible enough, but in the battle, they can't solve the problem by just dodging, this is Yan Xu's one-on-one has no problem, but once one-to-many, the shortcomings are exposed after not being able to solve the opponent in a short time.

But even if he knew these shortcomings, Yan Xu didn't have any good way, so he told the truth.
