The Spirit King's attitude is very resolute, it thinks that only when Li Jin is strong, its life can be guaranteed, this is the only mandatory function of the Concentric Ring that requires human life, and the Spirit King thinks that it is already in the weak stage, and now it is still in the growth stage, taking the dragon scale grass and those things given by Li Jin, plus it is voluntary, it will not cause too much harm to it.

What's more, once the Spirit King enters the Concentric Ring, he will not be able to come out for a long time, because the Concentric Ring does not allow the master to be threatened by these contract objects, unless Li Jin is stronger than them, in other words, as long as Li Jin's cultivation is not strong enough, the Spirit King can only wait slowly in the Concentric Ring.

Li Jin had long known the function of the concentric ring, and he also knew that there was no harm to the Spirit King in a small space, but he didn't want to hurt the Spirit King, but he felt the Spirit King's resoluteness, and then thought about the Spirit King's opinion, which was indeed reasonable, and he was ruthless in his heart, so he agreed, and the only requirement was to let the Spirit King not be reluctant.

Childhood memories involuntarily came to his heart, looking at the ancient word "deed" like a thunderball formed by the light filament, Li Jin couldn't help but sigh deeply, hinting that he had forgotten those unpleasant pasts, with the change of the handprint and silently chanting, two points of light floated into the eyebrows of the Spirit King and Li Jin.

The probe pressed his hand on the center of the Spirit King's eyebrows, the Spirit King lay there motionless, his eyes closed as if he was asleep, Li Jin's heart floated a trace of emotion, and the next moment his consciousness entered the Spirit King's mind.

A lot of flickering points of light appeared in front of him, it was the light of the soul, some of the points of light slowly changed, turning into countless complicated runes, these runes were rapidly combined, and they continued to drift away, forming the fragments of the battle that the Spirit King had experienced in the past, and there were also some scenes formed by the subconscious of the Spirit King, unconsciously, Li Jin was lost in these scenes.

A dragon chant suddenly shook Li Jin's mind and made him wake up suddenly, only then did he realize that he had almost made a mistake just now, and a layer of cold sweat had appeared on his head.

Li Jin's cultivation and realm are much worse than those of the Spirit King, but fortunately, the Spirit King's soul consciousness took the initiative to help, otherwise it would have been dangerous just now, he desperately restrained his mind, and only then did he re-see the constantly changing scene in front of him.

Fu culture has become a variety of skill symbols, constantly fluttering and changing, the scene of skill explosion in the symbol is constantly manifesting, because they are rapidly alternating and the position is also erratic, it is difficult for Li Jin to grasp their whereabouts, but this process of acquiring skills is very exhausting, and the more powerful the skill, the more difficult it is to capture, Li Jin does not dare to delay any longer.

Ordinary people get the spirit ring randomly, once they choose the demon spirit that needs to be obtained, they can only resign themselves to fate, otherwise who wants poor skills, how dare they pick and choose like Li Jin, that is, looking for death, fortunately, Li Jin has identified a rune symbol, and he shot without hesitation, and then withdrew from the soul space of the spirit king.

Li Jin's body trembled slightly, his mind was greatly consumed, but his face full of cold sweat had a look of expectation, the head of the Spirit King suddenly floated out some white points of light, and its body was also trembling slightly, these points of light recognized Li Jin, like a group of cheerful elves, fluttering into Li Jin's eyebrows.

When the point of light disappeared, the pale golden word "deed" in the air also slowly disappeared, the contract was completed, the dragon face of the spirit king had a deep exhaustion, and he fell asleep, Li Jin held it in his arms, and a thick apology appeared in his eyes.

In the first section of his left index finger, a dazzling orange spirit ring appeared, the orange meaning was very thick and deep, representing that the target was a fourth-order top demon spirit, and in his mind, a piece of skill instruction information also appeared, the skill name "Dragon and Tiger Change", ranking second among the skills of the Spirit King, and the strongest skill of the Spirit King was called "Tearing the Sky and the Earth".

The skill of "Dragon and Tiger Transformation" is a bit special, after the spirit body appears, it can instantly turn into a dragon or a tiger, but it cannot appear at the same time like the Spirit King, but it can be used alternately, the cooldown time is three minutes, and the cooldown time for the skill to be interrupted, destroyed or restarted is a quarter of an hour.

The dragon body turns into a silver dragon, hovering above Li Jin's head, which can attack the enemy with a fire dragon in his mouth, and can also use the dragon chant to deter the enemy's mind, and at the same time will form a full set of dragon scale armor on Li Jin's body, which is very beautiful, and feels very good, looks extremely heavy and strong, but is actually very light and flexible.

The spirit of the tiger turned into a silver tiger, sitting on top of Li Jin's head, it can be differentiated into a three-headed silver tiger phantom, with the characteristics of the "Xuanhu Ice Sky" skill, with a strong ice attribute attack ability, the physical attack ability is also very strong, and it can also attack the enemy in the air, the speed is extremely fast, and at the same time, it will give Li Jin a cold ice shield, which can be automatically defended, and the effect is average.

Li Jin tried to keep the spirit body in the original appearance of the spirit king, but there was only one effect, the spirit body changed into a combat form, and the body was much larger, and then jumped out to prepare to find someone to fight, Li Jin recalled it with a black line, it didn't look like it had combat power, and jumping out was to die, which was very spiritual.

In addition to the fact that there is no actual combat test effect, the skill of Dragon and Tiger Transformation is still satisfying, he has no time to fight now, sensed the surroundings, and found that there is no suspicious situation, so he took the Spirit King into the small space of the concentric ring, the Spirit King appeared on the small stone platform in the first circle, and Li Jin appeared in the pillar of light on the big stone platform.

Silently looked at the Spirit King for a while, the small stone platform where it was also raised a milky white pillar of light, and dots of golden light fell on its body from time to time, when those points of light merged into the Spirit King's body, the Spirit King obviously had a comfortable expression, and gradually snored again, thinking of the function of the concentric ring, Li Jin finally put his mind at ease.

Sitting in the pillar of light for a while, and realizing the feelings, Li Jin felt that the white pillar of light might be related to the spirit contract, those groove-like runes might be related to time variation, and the golden light points should be beneficial to the body and the soul, of course, this was all his guess, thinking of this, and looking at the spirit king again, he thought of the soul imprint.

Sure enough, above the pillar of light where the Spirit King was, a very small virtual image of the Spirit King appeared, floating there and sleeping, and there was an entity mark like a blood drop in the center of his eyebrows, it was really difficult to find if he didn't pay attention to it, Li Jin knew that it was the Spirit King's soul mark and a drop of essence blood, and it was also the existence of the Spirit King to save his life in the future, and he was finally relieved to see this.

Activating the spirit ring in his left hand, which stimulated the Heavenly Rank Bead, Li Jin's consciousness entered the small space of the Heavenly Rank Bead, the Heavenly Rank Bead has no life and soul, and it is used here as usual, summing up the recent battle experience, doing some mental feelings, adjusting his mentality, and entering a deep cultivation state.

The dantian world is still the same as always, there is not much change, the spiritual power is automatically circulating, there is no need for special attention, Li Jin's consciousness is traveling in the spiritual world, this time he did not choose to understand the battle, but is constantly feeling the changes in the power of heaven and earth.

Heaven and earth aura can be transformed into spiritual power, or it can be transformed into natural phenomena, they can be the embodiment of will, or they can be the embodiment of power, they can bring death, or they can give new life, ethereal, but everywhere.

Li Jin found that his understanding of the power of heaven and earth was still problematic, spiritual power was also a form of the power of heaven and earth, and the Great Zhou Tian Cycle could automatically absorb and store the aura of heaven and earth, and the effect of forcibly ingesting the aura of heaven and earth was not ideal, it could be completely flexible, maybe the effect would be better.

The changes and manifestations of the power of heaven and earth will have a specific fluctuation frequency and trajectory, and can even evolve into specific rune images and symbols, Li Jin can't understand their meanings, and he doesn't know how to crack those secrets, but he can feel that the transformation of the power of heaven and earth is related to each other.

His idea is that in the spiritual world, the changing forms of various heaven and earth forces are simulated, and there is no need to care whether they can be controlled, and these changes are evolved in the dantian world, and there is also no need to build runes, but to copy them through spiritual power, so as to trigger the evolution of the dantian world.

When needed, through the special induction of the dantian world, echoing the aura of heaven and earth that has not been transformed into spiritual power in those small circulation systems, triggering changes in the power of heaven and earth, and then through the release of spiritual power, a local power balance system is formed, once the spiritual power explodes, it will change the pattern of the power of heaven and earth around it, triggering a series of chain reactions.

This kind of use of the power of heaven and earth is very different from the transformation of spiritual power, not borrowing the power of heaven and earth, but triggering the power of heaven and earth to produce a series of reactions on its own, which can directly destroy the balance of power within the enemy's body, of course, it is difficult to control these changes, it requires long-term training, and it is difficult to predict whether it will be feasible.

In view of the previous painful experience, Li Jin did not delay in the spiritual world for too long, and gradually entered a normal state of cultivation, his cultivation and realm were also slowly stabilized, the golden points of light continued to integrate into his body, and his mind became more and more empty.

This cultivation time is very long, Li Jin also realized this when he woke up, his spiritual power has improved significantly, and his mood is also a lot more transparent, his cultivation is still in the early stage of building the foundation realm, but he has really consolidated the foundation, and the dantian world has changed a little, and the branches and leaves of the nine-petal silver lotus have borne nine crystal fruits, which are very small and beautiful.

The Spirit King was still asleep, just changed his posture, he looked peaceful, there was no sign of weakness, Li Jin was very satisfied with this, the aura in the pillar of light was very strong, and he was not worried about affecting the Spirit King's cultivation, looking at the other small stone platforms that did not light up the pillar of light, he sighed and escaped out of the small space.

Li Jin appeared in the original place, there were no living beings around, calculated the time, about more than twenty days have passed, that is to say, he has been cultivating in the concentric ring for nearly a month and a half, and there is no sign of breaking through his cultivation for such a long time, which is really a little uncomfortable, but after thinking about it, he also smiled, the higher the cultivation, the more difficult it is to break through.

Li Jin wanted to test his own idea, let go of the matter of obtaining another skill first, and when he cultivated to the foundation building realm, the power of "Shadowless Killing" must be improved, he always felt that the means of attack were too simple, lacking the feeling of momentum like a rainbow, and the use of power was too superficial and not profound enough.
