In the battle of "Starstriped Mountain Demon" and "Blood Feather Yunpeng", there is an obvious feature, many of their combat skill effects are not actually inspired by natural skills, they look like skills, but in fact, they are randomly deduced through the clever use of the aura of heaven and earth, combined with the different characteristics of the demon spirit power and the ontological bloodline.

Li Jin thought of the problem of "Shadowless Killing" and spiritual skills, although the power of spiritual skills is powerful, the disadvantages are traceable, there are fixed routines, it is likely to be restrained, and there is a limitation of cooling time, and it requires a huge demand for spiritual power, the speed of stimulation is relatively slow, and it is difficult to control the goals and effects of release.

"Shadowless Killing" is Li Jin's self-created combat technique, in addition to the demand for spiritual power and ontological combat effectiveness, it is characterized by the fact that it does not need to rely on foreign objects, does not care about the environment of the battlefield, and does not have any restrictions, as long as it is within the scope of ability, it can ignore the number of enemies and directly threaten the lives of the enemy, and it is strange and fast to send and receive from the heart.

It's just that "Shadowless Killing" also has a lot of shortcomings, it has extremely high requirements for the offensive and defensive ability of the body, and the demand for spiritual power is not small, and it also needs the strong support of the Divine Soul Consciousness.

Li Jin had already obtained the ability to release spiritual power, and before that, he had been trying to transform his spiritual power, trying to improve the power of the "Shadowless Killing", and the effect had also made him very satisfied, but after carefully analyzing the battle between the "Star-striped Mountain Demon" and the "Blood Feather Yunpeng", his concept had completely changed.

Spiritual power transformation is the most significant sign of the Crystal Transformation Realm monk, Li Jin can actually touch it in the current realm, it can only be said that he is a little monster, of course, he can't be too deep, this is also related to his cultivation and realm, the basic function of spiritual power release is to bless and extend the offensive and defensive effects, and it is the sublimation of the use of his own spiritual power.

These are not the focus of Li Jin's attention, what he is thinking about now is how to make the "Shadowless Killing" more powerful and perfect.

Heaven and earth aura, spiritual power, physical body, exercises and combat skills, how should they be combined, this is what Li Jin is thinking about now, the combat skills of "Star Striped Mountain Demon" and "Blood Feather Yunpeng", their ingenious use of heaven and earth aura, and other means, can be borrowed from the "Shadowless Killing", the key is to find a meeting point.

Li Jin originally wanted to use the spiritual power transformation as a meeting point, but unfortunately his ability was not enough to completely control it, and his perception of the will and power of heaven and earth was too far behind, and the spiritual power transformation seemed to only improve the power of the "Shadowless Killing", but there was no way to reflect the role of the aura and physical body of heaven and earth.

"Heaven and earth aura, physical body", Li Jin's thoughts wandered around these two issues, and after a long time, it suddenly became clear that he had let himself walk into a dead end of thinking, he had always thought that the aura of heaven and earth was used for cultivation, and spiritual power was the root of the battle, ignoring that the aura of heaven and earth was the source power of everything.

The "Heavenly Evolution Wall" once made an extremely detailed deduction for the battle between the "Star Striped Mountain Demon" and the "Blood Feather Yunpeng", and made a perfect interpretation of the process and fluctuations of their use of heaven and earth aura.

In fact, if you think about it deeply, whether it is skills, exercises, combat skills, or physical bodies, the ability of monks depends on the aura of heaven and earth, even if it is the improvement of the realm, it also depends on the understanding of heaven and earth, and the avenue of enlightenment.

Li Jin quickly thought of more, spiritual power is just the transformation form of heaven and earth aura, it is the energy essence of its own reserves, spiritual power is more for the monk's own use, it can be regarded as a kind of accumulation and capital, and heaven and earth aura is the infinite energy source and the ultimate weapon to strengthen oneself.

The meeting point has been found, cultivation must rely on the aura of heaven and earth to transform itself, strengthen the soul, refine the spiritual power, communicate with heaven and earth, and the battle should also use the aura of heaven and earth to improve the effectiveness, manifest the power, strengthen the offensive and defensive effects, and reduce their own losses.

Li Jin thought of this, and finally got a heart disease, he was ready to directly mobilize the aura of heaven and earth to control it in the future battle, and strengthen the power and effect of "shadowless killing", he didn't think at all, the aura of heaven and earth that he can mobilize now, whether it is quantity or quality, is extremely pitiful, as if this is insignificant at all.

Li Jin really didn't care about these, through the demonstration of the "Heavenly Evolution Wall", he already had a certain understanding of the fluctuations and changes of the aura of heaven and earth, and he also had some insights into the aura of heaven and earth, with the help of the "Heavenly Evolution Wall", he didn't care about the problem of use, as for the quantity and quality of mobilization, as long as the cultivation arrived, it could be solved, and what was needed now was practice.

Li Jin's idea is feasible, and it will scare people to death, if other monks know that Li Jin, who has not yet reached the foundation building realm, dares to think like this, and still wants to do this, he has to kill him alive, because the power of evolution heaven and earth is used in battle, and it is the monks of the Shenhai Realm who have only begun to involve it, and if the cultivation and realm are not enough, even if they think about it, they can't do it.

Li Jin's situation and cultivation are different from ordinary people, they are all made by themselves, and no one guides him, he knows little about some basic common sense, or even knows nothing, if it weren't for the appearance of the "Heavenly Performance Wall", he might have played himself to death a long time ago, so his ideas are also wild, and he does it when he thinks of it, and he is fearless.

"It's a pity that he is cultivating, if only he could fight in his cultivation, or experiment with the effect of his perception" Li Jin is not honest in his cultivation, he wants to play new tricks again, he doesn't want to end the state of cultivation, and he wants to experience the effect of comprehension, not to mention, not long after he gave up his gaze on himself and completely entered a meditative state, he really did it.

Li Jin entered the state of the Heavenly Rank Bead by simulating consciousness, combined with the effect of the "Heavenly Evolution Wall" on the battle scene reset, and constructed a picture of battle in his own spiritual world.

Then I imagined the possible changes in the aura of heaven and earth, added some details of the battle and different effects, and then decomposed the consciousness, induction and understanding respectively, the result was very good, very real battle charm, Li Jin affirmed that this method is feasible, and with the transition of time, these scenes have signs of solidification.

Li Jin woke up in his spiritual world, ready to watch the demonstration effect of the "Heavenly Performance Wall", but he was planted on the futon in a small space, and his consciousness escaped directly from the Heavenly Rank Bead, and his body also fell to the ground.

Consciousness to build the spiritual world, requires extremely strong spiritual power, needs the support of cultivation and realm, and also needs to understand the spiritual world, especially he also dares to differentiate consciousness and carry out different inductions, which is extremely dangerous, it is equivalent to splitting himself, and he also dares to fight and realize in the spiritual world for a long time, and he is lucky if he does not die.

The spiritual world built by Li Jin already has a certain prototype of energy, in other words, there are already signs of solidification, of course he does not have this ability, this is the credit of the purple qi in the Heavenly Rank Bead, but his foundation is too poor, and he doesn't know how to stop at all, and his consciousness can't bear it at all, so the current situation will appear.

In fact, in the spiritual world, there will also be dangers, the collapse of consciousness will lead to the collapse of the spiritual world, and in serious cases, it is possible for consciousness to die, Li Jin's situation is not bad, his spiritual world is far from being formed, but the consciousness will be very painful, and it cannot be recovered through cultivation, so it can only rely on sleep and time.

Fortunately, Li Jin is not stupid, he quickly understood his own situation, he didn't know the mystery of the so-called spiritual world, but he knew that he might be a problem caused by too much energy, he had encountered a similar situation, so he sensed it slightly, and found that there was no dangerous breath, so he simply endured the physical and mental discomfort, and fell asleep.

Three days later, Li Jin's situation improved, he didn't give up the idea of cultivating in the spiritual world, but he didn't have the intention of trying again in the short term, he couldn't run away anyway, he would slowly adapt, what made him happy was that he realized in the spiritual world, and his cultivation was not delayed, and the dantian world also changed.

The dantian world itself is still the same, what has changed is its reaction, in the case that Li Jin tried to mobilize the aura of heaven and earth, and did not use the spiritual power of the dantian, the power of the dantian and the spiritual power circulating in the big and small Zhou Tian, there are signs of echoing each other, it seems that between the aura of heaven and earth and them, there is a mysterious induction.

Li Jin used to communicate the aura of heaven and earth through the dantian, form a spiritual power circulation system, and transform himself, but now he wants to directly mobilize the aura of heaven and earth through consciousness, which is logically related to the dantian and the big and small Zhou Tian, it is the use of the power of heaven and earth, so this situation has also aroused Li Jin's attention.

Li Jin found that the aura of heaven and earth was difficult to control, and it was not easy to turn into the form and state he wanted, but the participation of the dantian world had greatly improved the situation, and it seemed that the dantian world had become a microcosm of heaven and earth, and it had an additional ability to control the power of heaven and earth, and was very sensitive to the changes in the aura of heaven and earth.

Li Jin quickly realized that this is the manifestation of the foundation building realm, and the biggest feature of the foundation building realm is to form a dantian qi sea, build a rune world, sense the power of heaven and earth, and mobilize a certain amount of heaven and earth aura, which can quickly replenish his spiritual power, restore his combat ability, repair injuries, strengthen himself, and improve the power of his body and skills, and his cultivation will be much stronger than that of the innate realm.
