Now Du Xu can finally calm down and sort out his comprehension during this time, in addition to the ethereal mental progress, the most important thing is that Du Xu has finally comprehended part of the principle and origin of cultivation, and finally got out of the situation of knowing what it is and not knowing why it is, and he is not ignorant of the mysterious practice.

He finally knew how to exert his powerful soul power to explore the origin of spells, magic weapons, and even cultivation, and now Du Xu used the colorful cloud magic weapon to protect the room and began to experiment with spells.

Pinching, chanting, and mana exude a unique fluctuation, attracting the spirit of heaven and earth, Du Xu did not omit any of the steps of the spell, and in accordance with the requirements of the release of the spell, he cast the spell step by step, and the powerful innate soul scanned the whole process with the help of the power of the Kunlun Mirror.

Du Xu felt that the trick and spell had caused the response of heaven and earth, with a principle that Du Xu did not understand for the time being, causing changes in the mana in the body, yin and yang true qi mixed with the mana formed by the innate divine soul, there was a pure feeling, but the fluctuations of heaven and earth caused by the trick and spell quickly affected and transformed the nature of mana to a unique frequency, Du Xu released a subject trick, and the frequency and fluctuation of mana were close to a force field nature.

Under the guidance of Du Xu's own unconscious, under the response of the spirit of heaven and earth, the mana released a strange fluctuation, under the observation of Du Xu's divine soul, suddenly a jumping talisman flashed in his eyes, not spinning! There were more and more jumping talismans, and finally a simple talisman array formed by 89 talismans was formed, which quickly spread into an invisible and colorless force field under the infusion of heaven and earth vitality.

Du Xu's force field transformed by the talisman is like an arm command, and it should be applied from the heart.

"89 runes, all belong to the "Five Elements True Fu" recorded in the 129,600 five elements of the true runes, 89 runes, a total of 9 kinds of runes, five kinds of rune structure, are the West Kunlun Tibetan Dharma Hall collection book "Shangqing Five Elements True Rune Solution" recorded in the five elements of the true runes of the ninety-nine kinds of changes, according to the classics record of these five kinds of rune structure is to control the direction of power, control the output of power, control the change of the nature of power, control the autonomy of power, control the power of the attribute of the rune structure. ”

"And the nine kinds of Five Elements True Talismans are all talismans that represent force or position, through the talisman to attract the power of the heaven and earth Yuan Qi to generate the force field, and through the rune structure to control the change of force field power, the spell structure of a subject technique is completed!"

Du Xu temporarily pinned the innate soul on the Kunlun Mirror, not worrying about the carrying capacity of **, and could unscrupulously exert the powerful computing power of the innate soul, but this time should not exceed an hour, otherwise there is a risk that the soul will fall out of the body, even if it is controlled within an hour, it will take Du Xu a year to carefully polish the connection between the soul and **.

Under the instantaneous deduction and change of hundreds of millions of times of the innate divine soul, the structure of the talisman of the object technique and the nine kinds of 89 true talismans of the five elements were quickly dismantled and changed, and through the repeated trials of the divine soul, the original face of the five elements talisman was gradually discovered. Du Xu not only corrected a few small omissions in the photography technique, but also supplemented and improved some of the mistakes and omissions. With the receptive spell again, not only the change of the spell is more flexible, the power of the force field is more powerful, and even the speed of activation is doubled.

In the end, the nine types of Five Elements True Talismans increased to twelve, and the five types of spell structures increased to seven, but the 89 Five Elements True Talisman was reduced to 72, which made Du Xu's speed of launching spells several times faster, and the spell control was more flexible and powerful, and of course, the control was more difficult. This is not to say that Du Xu's improved spells are better than the spells that the West Kunlun Qi practitioners have been tempered thousands of, it can only be said that Du Xu's improved spells are more suitable for himself.

Of course, Du Xu's purpose is definitely not to improve one or two spells, but more importantly, to strengthen his understanding and knowledge of cultivation through improving spells.

Du Xu silently thought about the spell rune composed of these seventy-two runes in the sea of knowledge, attracting the yin and yang true qi in his body, and wanted to record this spell rune, but each time it collapsed halfway through the composition! He tried several times, and the most successful one only lasted a few breaths before it collapsed into true qi.

Du Xu's idea is simple, that is, first form a spell rune seed in the body, and then you can directly send out a spell, as long as the mana moves, a spell will be issued. There is no need to waste time outside the body, and the talisman of spells is formed, which saves mana and time.

It is normal for him to have this idea, but repeated failures have forced him to look for the factors of failure and sum up experience. After ruling out the possibility of failure one by one, the only possibility is that the nature of Yin and Yang True Qi is not enough to carry the spell rune, the true qi is a simple essence energy, and the spell can only be triggered by the combination of essence power and spiritual power into mana, which shows that the stability of the spell rune must be the participation of spiritual power.

In this way, only after Du Xu breaks through and perfects the Dao foundation, he enters the demarcation point of life cultivation, and his soul goes out of his body, and his true qi is wrapped to form mana, or his true qi melts into the gods, and the spirit and flesh are united to form the true yuan. Only when the power of this essence and spirit triad is generated, can a spell rune be directly formed in the body and a spell seed can be cultivated.

Du Xu didn't know, he inadvertently speculated on the cultivation requirements of the next realm, this is in the True Yuan Out of Body Realm after the completion of the Dao Foundation, there is a name called Fa has a true form, which means that the true form of the spell is stored in the body. This attempt was unsuccessful, but it laid the foundation for Du Xu's future cultivation, and it can be said that as long as Du Xu firmly remembers today's perception, then his path to the True Yuan Out-of-Body Realm will definitely not lose his way.

Now that the experiment has reached a dead end, Du Xu no longer continues to entangle, quickly retracts the innate soul from the Kunlun Mirror, and runs a few circles of mana slightly, feeling that the feeling of separation of spirit and flesh slowly recedes, Du Xu picked up his experiment again.

Since there is no way to think of the talisman in the body, what if the talisman is placed outside the body? Du Xu turned out a few pieces of Xuantie from the Kunlun Realm, and a mouthful of yang fire erupted, melting the Xuantie into the Xuantie liquid, and constantly playing the magic trick in his hand, submerged in the Xuantie liquid, countless Five Elements True Talisman went in and out of the Xuantie liquid, constantly bringing out the impurities of the Xuantie, and the essence of the Xuantie liquid in the air became more and more pure, shrinking from the size of a basketball to half the volume, and the color also changed from black to dark purple.

Du Xu pinched the magic trick in his right hand, divided the mass of Xuaniron into ten parts, and shouted, countless runes flowed into the ten groups of Xuantie like water, forming ten kinds of spell rune seeds in the Xuantie, and a stream of Xuanyin cold qi sprayed on the ten groups of Xuantie liquid, quenching the ten groups of Xuantie into ten iron cards.

The iron plate is engraved with ten different patterns such as big hands, scorching sun, cold ice, heavenly maiden, jair, golden shield, wings, etc., representing ten kinds of spells, as long as Du Xu's true qi and the spell rune seeds on the iron card are compatible, you can launch the spell in your mind, the power is very powerful, it is Du Xu used to understand the essence of the spell, and understand the mystery of the true yuan realm in advance.

Du Xu was in high spirits for a while, constantly taking out the things that were scavenged from the hands of the reincarnators from the Kunlun Realm and refining them, and for a while he didn't know how many whims he had experimented with.

The most powerful thing is a small spaceship, a small iron-blooded spaceship brought back by the reincarnators from the world of Alien vs. Predator, which was originally a mobile vehicle for the reincarnators, but because the spaceship could not be used in the real world, it had to be handed over to Du Xu in order to exchange points, but Du Xu also paid a high price of 90,000 money.

In fact, the iron-blooded spaceship is actually a kind of goods, and the high-tech products in it are not applicable to the laws of the real world, and what Du Xu bought in his hand is just the metal shell of the spaceship, and the various parts inside are completely waste.

But Du Xu has a wonderful idea, if the function of the parts of the spaceship is simulated with a magic weapon, can the spacecraft be started? Du Xu's West Kunlun Dao Sutra records many refining methods for constructing large-scale magic weapons for war, and the first place is the Sun Chariot refined by the Eastern Emperor Taiyi, which is said to be a chariot, but it is actually a war fortress refined with a large star in the starry sky of the Flood Wilderness, and when it flies over the Flood Wilderness, it is like a small sun, composed of nine major parts, which is powerful and shocking.

Of course, Du Xu didn't have such great ambitions, what he wanted to refine was a small construction magic weapon "Xingyun Che", which was light and fast, and it was the best substitute magic weapon. It just so happened that Du Xu had the cloud magic weapon seized from the black-robed evil cultivator, and if he refined it into the iron-blooded spaceship, he could refine the Xingyun Chariot to the second level of prohibition in one leap, and the speed in the sky was definitely not inferior to that of ordinary civil airliners, and at that time, Du Xu could also proudly shout: "I have a private spaceship!"
