At this critical moment, fortunately, there is also a fragment of the Baiyang Heavenly Book in his hand from the Knee Corner Daoist, which is simply tailor-made for Han Cheng, and the content is in the same vein as Du Fan's "Baiyang Illustration" when he entered the Dao, and it is the method of cultivation in the sword immortal stage.

There are detailed diagrams and cultivation formulas of the Lingxu realm and the Purple Mansion realm, as well as a supporting Baiyang sword technique and several powerful magic powers, but they can only be fully exerted after stepping into the Lingxu realm.

Han Cheng suppressed the excitement in his heart, and decided to practice the Fa first, and then practice the Fa, and there was nothing wrong with practicing step by step according to the content of the fragments of the Heavenly Book, anyway, he was not in a hurry for a day or two.

If it is said that during the period of the realm of the gods, the level of the soul is only a process of preliminary exploration, the realm of Lingxu is to focus on how to nourish and exercise people's souls, further tap the potential of the human body, and finally condense people's souls into primordial spirits, get rid of the fetters and shackles of the physical body, and unite heaven and man, and you can use the primordial spirit to intuitively feel the rules and mysteries between heaven and earth.

The soul is the original power of man, and when it is not sensed, it is ignorant and thoughtless, very fragile, easily escaping, and has no power.

After sensing it, it will gradually psychic and have supernatural powers beyond the mundane, but the soul itself is still relatively fragile, once damaged, without the assistance of external objects, it is extremely difficult to recover, if the human body is destroyed, the soul will soon be worn out, almost difficult to survive, it can be said that the body and spirit are destroyed.

Mortals have a body and soul, and if they have not been condensed, they may be in the form of smoke, and they can be detained by the evil way to refine magic weapons, and once they encounter this situation, they can't even be reincarnated.

Among them, those who have long-cherished roots, their souls will be much stronger and more condensed than ordinary people, and their foundations will be thick, and they will occupy a great advantage in the process of cultivation, which is also one of the criteria for measuring the qualifications of root bones.

The human soul is composed of three souls and seven spirits, the three souls are the master of knowing God, and the knowledge of God is the master of the body, and people's words and deeds are controlled by knowing God and the three souls.

The seven spirits are felt by the seven senses, which are divided into the central spirit, the heavenly spirit, the spiritual wisdom, the spirit, the spirit, the heroic spirit, and the strength.

Among them, the central spirit can enhance the ability to control the soul, the heavenly spirit can enhance the speed of the soul's thoughts, the spirit wisdom can clear the soul and eliminate unnecessary interference when thinking about problems, the spirit and spirit, as the name suggests, closely link the soul with the essence and qi, which is one of the keys to breaking through to the purple realm, and the heroic spirit can enhance the resilience of the soul, and the strength can enhance the strength of the soul.

The human body is the vessel of the soul, which protects the soul from harm. But it also restricts the action of the soul.

The description of the cultivation of the Lingxu realm in the Baiyang Heavenly Book is to the effect that by absorbing the spiritual energy of heaven and earth, the essence of the sun and the moon, and exercising and nourishing the three souls and the seven spirits, so that they will continue to grow, and finally condense and unite to achieve the primordial spirit.

Once the original spirit is achieved, the essence of life will take a qualitative leap, once the human soul is separated from the body, it is easy to be blown away by the wind, the initial Yuan Shen is tangible and non-qualitative, and cannot leave the body for a long time, but after enough tempering, it can withstand the chaos of the material world, and can leave the body and travel out of the body.

In addition, there are many other benefits, such as the ability to control the mana of the aura has been greatly increased, the reaction time from thought to action has also been greatly reduced, making the casting time shorter, the control of flying swords and magic weapons is more accurate, the distance is also longer, and the spell can be cultivated to a higher level, etc.

The most important thing is that when the primordial spirit is strong to a certain extent, it can directly interfere with reality without using magic, such as transfiguration attacks, such as distraction thoughts, and divine thoughts shrouded for tens or hundreds of miles;

After practicing the special secret method, you can also use your divine thoughts to carry out spiritual attacks, and even under certain special conditions, you can also possess the body, re-practice the Dao, and restore part of the mana before death, but the sequelae after taking away will be relatively large, and the path will be limited because of this, and it is difficult to go to the next level.

Even if there is no suitable host, you can rely on the remnant god to practice the ghost path exercises, and see the light of day again in the form of a soul body. It's just that this method is more dangerous than possession and seizure, and it cannot be done without other choices.

When he first practiced Baiyang Tianshu, Han Cheng also communicated with Qin Ziling several times one after another, not so much to communicate, but to ask for advice.

During this period, he also told the Qin sisters about his experience in the past few years after entering the Huayu Cave, but he didn't deliberately keep anything.

When she first met Han Cheng outside the valley, Qin Ziling was originally curious about why his cultivation had improved so quickly, and in just a few years, he had advanced from a mortal swordsman in the late stage of Qi cultivation to the late stage of Tongshen.

Guessing what kind of big opportunity she probably had, in order to avoid causing Han Cheng's suspicion and misunderstanding, she has been buried in her heart and did not say it, but she didn't expect the other party to take the initiative to tell herself, after learning that she had many adventures in the past few years, although she was also a little envious and jealous in her heart, but she was not so red-eyed, but more emotional, feeling that Han Cheng's fortune was thick and lucky.

She didn't have any intention of peeping at the remnants of the Baiyang Heavenly Book in Han Cheng's hand, her Heavenly Fox clan had its own set of inheritance techniques for Dao Heavenly Immortals, and other Heavenly Books were really not very eye-catching unless there were those who could Dao Golden Immortals.

Han Cheng also guessed this point, so he dared to tell the other party that he had the white sun remnant in his hand, if the other party was interested, it was a big deal to participate in the research together, so it was more convenient to ask for advice, he couldn't ask for it!

Regarding the difficulties encountered by Han Cheng in his cultivation, Qin Ziling did not be too stingy when she saw the love of her little sister Han Cao, she shared her feelings about how to practice and impact the Lingxu realm with Han Cheng one by one, which opened Han Cheng's eyes and benefited a lot.

With Qin Ziling's advice and help, Han Cheng's cultivation of the White Yang Heavenly Chapter did not encounter too many obstacles.

In the early morning, Han Cheng sat quietly in the valley where the aura was strong, surrounded by abundant heaven and earth aura.

Between the breaths, the pure aura of heaven and earth is collected in the breath, and the five internal organs are circulating, nourishing the internal organs at the same time, and there is a subtle connection with the Mud Pill Palace.

After that, there was a cool breath of the moon essence that penetrated out of the heavy pass, pouring into the Mud Pill Palace, and the spirit and qi were combined, nourishing the three souls and seven spirits in the soul and promoting its growth.

In this way, in less than three months, Han Cheng was surprised to find that the wounds in the soul were not only all repaired, but also the three souls and seven spirits were more condensed, the true qi and the soul complemented each other inside and outside, with the soul to control the qi, to nourish the soul with the qi, to embrace each other, and the cultivation can almost be described as a thousand miles in a day.
