The information in the ancient mirror made Wei Wuxian realize that this secret technique was extraordinary, and he was also frightened by the sentence 'life and death are up to the sky', presumably Xuan Yazi should have been the same as himself when he got it, and his heart was also extremely entangled!

Wei Wuxian is currently within the scope of adaptation of the secret technique, and if he cultivates further, it will be ineffective, and he must make a decision as soon as possible whether to use it or not, it is rare to have such a good cultivation environment, and when he goes out of here, he may not be able to find a suitable place outside.

The mending technique needs to be completed in an extremely quiet environment, and it must not be disturbed in the slightest, otherwise you will die of horror on the spot. Any spell involving the divine soul must be extremely careful, this place is secret, if it is confirmed, it is best to cultivate the 'Heaven Mending Technique' in this Earth Fire Room.

As for what kind of artifact to use as a natal spiritual weapon, he already had a goal, which was the 'Tianyi Heavy Water' that he got from Hu Tianmei of the Spirit Plant Academy last time.

The utensils mentioned by Xuan Yazi are not only finger weapons, but also materials and spiritual grass, the purer the better, 'Tianyi Heavy Water' is the most valuable artifact that Wei Wuxian can get his hands on.

Wei Wuxian knew that once he stepped out of this fire refining room, he would no longer have the courage to try it easily, so he simply stayed in the room and pondered, but he soon made a decision, since Providence had allowed him to come here and obtain a secret technique that suited him, what reason was there not to do it.

No other considerations are made at this time. Shen Tao and the others are thankful, and they should not have a big problem. He inspected the stone door outside, then cleaned up the room a little, placed the hourglass on the stone table, took a Yuan Qi Pill, and sat cross-legged on the stone bed.

Two hours passed, Wei Wuxian opened his eyes, and felt that his spirit and spirit were in the best condition, and only then did he take out the drop of 'Tianyi Heavy Water'.

'Tianyi Heavy Water' is like a drop of ink when presented alone, and when it enters the water, it becomes clear and clear, and a small drop weighs a thousand catties, which is extremely precious.

Wei Wuxian seemed to see Xuan Yazi from the ink beads, it was a young boy as young as himself, with a calm and resolute face, and he was also sitting cross-legged on the stone bed, as full of ambition as himself, fantasizing in his heart that he would change his life and move towards a new world.

The more Wei Wuxian thought about it, the more agitated he became, he hurriedly gathered his mind, took a deep breath, and after his mind calmed down, he meditated on the 'Heavenly Replenishment Technique' several times, confirming that he knew every detail well before swallowing the drop of 'Tianyi Heavy Water' in his hand with a mouthful of true qi!

'Mending the Heavens' is a secret technique, not a practice, no need to practice, as long as the conditions required for it are met, and the steps can be followed.

There are two conditions: first, it needs to be cultivated to reach the realm of parasitic spirits, but it cannot exceed the seventh layer of the qi refining period, and second, it is necessary for the giver to have an artifact that carries the second foundation.

If the two conditions are met, it can be started, and there is another advantage of the Heavenly Replenishment Technique, that is, it does not change the previous Dao Foundation, and can coexist with it. It is equivalent to using the 'Heaven Mending Technique' successfully to have two Dao bases at the same time, which overlap each other, one is explicit and the other is implicit, and does not interfere with each other.

This method has high requirements for the utensils, the purer the utensils, the better the grade of the hidden Daoji, and the attributes of the utensils also determine the attributes of the Daoji.

'Tianyi Heavy Water' is the essence of water, a drop of 'Tianyi Heavy Water' needs to refine a pool of water to obtain, pure and pure, with it as a natal spiritual weapon, Wei Wuxian's induction, understanding and control of water attributes will reach an extremely high level.

Because Wei Wuxian still had the original Manifest Dao Fundamental, it didn't affect his cultivation and other attribute exercises, but it would be a world of difference compared to the water attribute!

Although the 'Tianyi Heavy Water' was only one drop, it weighed a thousand catties, and before it was refined, he didn't dare to be careless at all, and slowly sent it to the dantian wrapped in true qi.

The first step is to refine the artifact and make it fit with oneself, and then to send the soul.

According to Wei Wuxian's secret technique, the fire of the True Yuan of the operation itself was used to quench that drop of 'Tianyi Heavy Water', and this process took a long time, and he couldn't be rushed, otherwise it would damage the quality of 'Tianyi Heavy Water'.

After refining, the 'Tianyi Heavy Water' is like a part of Wei Wuxian's own body, and he doesn't have to worry about it crushing his abdomen in his body, and it is like an arm and a finger.

Wei Wuxian hadn't thought about refining 'Tianyi Heavy Water' before, but the method of refining artifacts was a secret that the major sects did not pass on, and there was no purchase outside, which was why he attached so much importance to the identity of the inner disciple, and the difference between the inner door and the outer door was far beyond the imagination of ordinary people.

The method of mending the heavens includes the method of refining utensils, the method of dividing the soul and sending the soul, and the method of warming and nourishing utensils and divine souls. Each of them is a great secret technique, but it is only one of them in the 'Heavenly Replenishment Technique'.

Wei Wuxian carefully refined that drop of 'Tianyi Heavy Water' little by little, and did not dare to be negligent in the slightest, this was related to the grade of Dao Ji in the future, and he would never allow even a little flaw to appear. Three hours passed, and he confirmed that the drop of 'Tianyi Heavy Water' had been thoroughly refined by himself, and then he breathed a sigh of relief, it would not be easy for anyone to put a drop of something weighing a thousand catties in his body.

After the first stage was completed, Wei Wuxian first took a Yuan Qi Pill to restore his Yuan power, and after another hour, he waited for his mind to be at peace before he began the second stage of the 'Heaven Mending Technique'.

The second stage is to split the soul, which is to strip one-third of one's own divine soul and then send it to the 'Tianyi Heavy Water' as quickly as possible.

This process is very dangerous, and whether or not you can complete the stage of 'mending the heavens' is very important. Even Wei Wuxian, who had always been calm and calm, had a little bit of a heart at this time, and he was more patient and careful than when he had been refining the 'Tianyi Heavy Water' before.

Wei Wuxian followed the method of dividing the soul, concentrating and calming down, and returning to the most secret places of his body.

There is a small cloud of smoke and mist, ethereal like clouds in the nine heavens, high and far and silent, deep as the abyss under the sea, mysterious and impermanent. If you look closely, it looks like a burning blue fire, swaying and shining.

This is the fire of his divine soul, the fire destroys people, and the fire is strong!

Wei Wuxian divided one-third of his Divine Soul, and his body would inevitably be affected to a certain extent in the short term, and at that time, he would need to continuously use the Soul Nourishing Technique recorded in the 'Heavenly Replenishment Technique' to nourish and strengthen his Divine Soul.

As the hourglass passed, Wei Wuxian's face gradually turned pale as paper, and his whole body shook like chaff.

He seemed to be in great pain, and his forehead was bruised and he was sweating like pulp, and this state lasted for most of the hour, until the last bit of sand left in the hourglass also fell, and he did not open his eyes from the meditation.

Although he looked haggard, his eyes were full of excitement.

This 'mending the heavens' is much more complicated and difficult than he imagined, almost failed in the time of splitting the soul, peeling off the soul not only hurts the heart, but also makes the mind lose its autonomous consciousness, just when he fell into the illusion, the ancient mirror in the sea of divine consciousness saved him, the ancient mirror suddenly shook at the last moment, and made a clear sound, pulling him back from the lost.

Wei Wuxian recalled the thrilling scene before, touched the cold sweat on his forehead, and secretly rejoiced.

After resting for a while, he closed his eyes again, experiencing the mysterious feeling that he had never felt before, every meridian, bone, fur, viscera, etc. in his body seemed to be given a second life, especially to the water attribute vitality in the body was extremely close, the change was from the heart, and it could be easily extracted from the mixed five elements vitality without transformation.

This is a very big change, in the past, when he cast a water attribute spell, seventy or eighty percent of the vitality was lost when transforming the yuan power, but now using the water attribute spell alone only needs to extract the water attribute vitality from the mixed vitality in the body, and it can be completely transformed into a water attribute magic weapon or cast a water attribute spell by the yuan force.

Whether it is a monk driving a magic weapon or casting a spell, it needs to be achieved through Yuan Li.

Yuan Li is transformed from various attributes of aura, yin, and evil energy. Magic weapons and spells with different attributes also have different requirements for Yuan Force: metallic magic weapons and spells need metal Yuan Force to drive, and wood attribute magic weapons and spells need to be driven by wood attribute Yuan Force, so generally monks practice single-attribute exercises, so that the Yuan Qi accumulated in the body can be completely converted into Yuan Force for use.

If he didn't do this, then just like Wei Wuxian was now, the vitality absorbed in his body was mixed, and he couldn't make full use of the vitality in his body when using magic weapons and casting spells, and seventy or eighty percent of the vitality that was not suitable for magic weapons and spells would be lost in vain during the transformation process.

It is precisely because of this that although Wei Wuxian's cultivation has advanced by leaps and bounds after completing the [Five Elements Technique], the vitality accumulated in his body is stronger than that of the ninth-level cultivators in the Qi refining period, but in terms of durability, it is far inferior to Xie Sanyi and Gu He and others, because a large amount of vitality is wasted when transforming the Yuan Force, and at most it uses up to thirty percent of the actual amount.

This is also the reason why he first sent the seven sons of the Qingyang Sect to defend the city during the battle yesterday, and did not make a move until the last moment, and he couldn't hold out for too long with all his strength.

Now that I have the second Dao Foundation, it is a little better than before, and if I want to change it completely, I can only find a water attribute exercise to cultivate, but how can the Great Dao Method be so easy to obtain, now I can only do it first, step by step.

In addition, if you change your major exercises, in addition to the water attribute spells and magic weapons, the other attribute spells and magic weapons that you have cultivated before will not be able to be cast and used, and the completion of the Five Elements Technique will become meaningless, wasting a lot of energy and Yuan Jing.

This is an unavoidable question, Wei Wuxian had thought about it when he chose to cultivate the 'Heavenly Mending Technique' here, you can't have both fish and bear's paws, and in the long run, of course, it is more important to change your own Dao foundation.
