An important reason why Tong Yu didn't want Cai Zijing to interfere with the Water Source Sutra was because of the cold spiritual water.

Although the Hanyi Spiritual Water is good, how can it compare to the Xuanming True Water?

Cultivating the Water Source Sutra based on the Xuanming True Water is bound to bring the power of this Immortal Sutra into full play.

If Cai Zijing instructed him to practice, replacing the cold spirit water would definitely be able to detect the abnormality.

After you have practiced for a while, you can find other excuses to cover up the past.

The only thing that worries him is that he is a fellow practitioner of gold and water, and if he cultivates with Xuanming True Water as the foundation, Xuanming True Water as a divine water is at a higher level than Taibai Jingjin.

In this way, will there be a situation where gold and water will be restrained, which will be very disadvantageous to him.

However, after thinking about it, Tong Yu still decided to give it a try, if such a situation really happens, then it is a big deal to let the water spirit creature suck away the Xuanming True Water.

His mind came to the side of the Consciousness Sea Spirit Creature again, he couldn't do all this by himself, and he had to ask the Water Spirit Creature to help.

Tong Yu passed on his thoughts and requirements to it little by little, and asked it to drop a drop of its own divine water into the sword washing pool.

To Tong Yu's surprise, the water spirit creature sensed its thoughts, and immediately conveyed the idea of resistance, it was unwilling to give up any bit of divine water that gave birth to itself.

Tong Yu was dumbfounded, he didn't expect to have trouble with this joint at all.

It took a long time to work, but the water spirit object did not give in, and there was no intention of compromise.

It's like a stubborn child, no matter what Tong Yu says or promises, it doesn't give a little.

"Lao Tzu is such a big black mist, so much Xuanming True Water has been absorbed by you, and now I beg you, but you are like an uncle. ”

Tong Yu was so angry that he scolded: "A drop of water is nothing to you, right? This is very important to Lao Tzu, you know?"

The water spirit creature rippled and swirled around Tong Yu's thoughts, like a naughty child, but he just refused to agree.

Tong Yu tried his best, and the only thing that attracted some attraction to the water spirit object was the Liyuan River, this ancient remnant water vein was the only thing he was interested in the water spirit object he had tried.

It is the cold spirit water in the washing yuan pool, and the water spirit objects are too low-level, and they don't have any interest.

"It's impossible for me to give it to you in Liyuanhe, you will die of this heart!"

Tong Yu angrily conveyed his angry emotions, Liyuanhe is not only a treasure, but also has other meanings, it is the treasure of Dali Patriarch's sacrifice.

Now everyone knows that if he disappears for no reason, then the Flying Immortal Gate will definitely be traced.

Moreover, in order to replace Hanyi Lingshui and abandon the Liyuan River, Tong Yu was also a little reluctant.

But the water spirit creature is still in its gestation, and its instinct makes it refuse to give up any bit of divine water, but Tong Yu can't use the tortoise shell at this time, so it's helpless.

"Can we only use the cold spirit water as the foundation to cultivate the Water Source Sutra?"

Tong Yu frowned, this was really not what he wanted to see.

"Water Source Sutra..."

Tong Yu muttered these three words, his heart moved, and he looked at the water spirit object again.

He tentatively passed on the water source he had comprehended to the water spirit through the water mysteries in the Tianyuan Realm, that is, the several forms of fog, snow and ice, the root of water, and so on.

To his surprise, the water spirit creature was actually extremely interested in this, and the water rippled, circling around him, and even conveyed a little longing to Tong Yu.

It has an instinctive desire for the way of water contained in the Water Source Sutra.

"Hahahaha!"

Tong Yu laughed, it's really another village!

He just thought that although the water spirit creature was in the process of being conceived, it was extremely extraordinary, and even based on the Dao diagram, but in terms of water travel, it seemed to be different from the water source scripture he obtained.

Just with the idea of giving it a try, who knew that the water spirit creature seemed to be really interested in it.

"If you want me to preach for you, pour a drop of your divine water into the sword-washing pool. ”

Tong Yu began to continue to negotiate with it on the conditions, and said, "In the future, if I have any understanding on the water line, I will share it with you." ”

His current comprehension of the Water Source Sutra is only a little superficial, and he doesn't dare to go too far.

The water spirit creature circled around him a few times, as if to measure, and finally agreed.

A water-walking divine light appeared directly on the sword washing pool in Tong Yu's dantian, the water rippled, and a drop of dark blue and almost black water fell in the sword washing pool.

This drop of water is different from the Xuanming True Water, which has obviously changed after being absorbed by the water spirit.

But after this drop of water appeared, a bone-chilling chill instantly rose in Tong Yu's dantian, making his whole person seem to be frozen all of a sudden.

The ice-blue flame in the sword washing pool was instantly extinguished when the water droplets fell.

In front of this drop of divine water, Hanyi Spiritual Water did not have any resistance power, and quickly integrated into it.

And the Qi Sword formed by cultivating the Heavenly Law Sword in the Sword Washing Pool was also almost collapsed after the divine water dropped, shrinking by most of it.

The sword washing pool made of etheric white essence gold vibrated slightly in Tong Yu's dantian, and the golden-white luster of the whole body shone, and all the runes on it lit up, faintly unstable.

Sensing all this, Tong Yu trembled, he was afraid that the sword washing pool would not be able to withstand the shattering, then he would probably be directly tragic.

Fortunately, the water spirit creature also seemed to be aware of the crisis of the sword washing pool, and the water walking divine light directly shrouded the sword washing pool, and the dao pattern loomed in it, and the sword washing pool quickly stabilized.

However, in a moment, the water spirit creature withdrew the water spirit light, and a new sword washing pool appeared in Tong Yu's dantian.

After the tempering of the water walking divine light, the sword washing pool was one size smaller than before, and inside it was half a pool of dark blue and almost black liquid.

The white essence gold that cast the sword washing pool seems to have been tempered by the divine light of the water line, although it is pure gold, but at this moment it is glowing with water, and it is integrated with the divine water in the pool.

The entire sword washing pool is completely natural, and it is not at all like the acquired sacrifice.

"Whew!"

Tong Yu exhaled a cold breath, and a mist immediately appeared in the air in front of him.

The changes in the Sword Washing Pool made him very satisfied, and he also passed on all the true meaning of the water from the Water Source Sutra that he had comprehended to the water spirit, which might help its growth a little.

Subsequently, Tong Yu began to cultivate again.

He did not directly cultivate the Water Source Sutra, but re-cultivated the Tongtian Law Sword.

The sword vitality cultivated was refined by the divine water in the sword washing pool, and most of it was turned into the divine water, leaving only an extremely pure and condensed point.

Tong Yu was stunned for a moment, the sword vitality cultivated in this way was pure enough, but the speed of cultivation was bound to slow down greatly.

Not to mention that compared to his previous cultivation speed, I'm afraid it is not as good as that of ordinary monks.

"There are gains and losses, and in order to build a perfect foundation, I can't be in a hurry. ”

Tong Yu can only comfort himself like this.

After cultivating the Heavenly Sword once, he began to officially cultivate the Water Source Sutra.

Fog ** Snow Ice, the cultivation of the Water Source Sutra is very different from the ordinary water attribute exercises, it starts from the 'fog', and it is still a very rare practice of refining qi and cultivating the spirit at the same time.

The mist cultivated also has a special name, the mist of the gods.

Tong Yu let himself relax physically and mentally, imagining that his mental strength was fluffy, like a mist.

Then, according to all the changes in the misty mist recorded in the Inheritance Brand of the Water Source, his spiritual power also changed, as if he himself had also incarnated into a light and ethereal mist.

After being reborn, Tong Yu's spiritual power was naturally strong, and besides, he had also cultivated several spiritual secret techniques, so the Divine Mist was not difficult for him.

When his state of mind and thoughts matched the artistic conception of the misty mist, a little mist quietly appeared in his dantian.

The mist was viscous, pale black, and cold, and it swirled around the sword washing pool, although it was not all dissolved by the divine water in the pool, but it also contained a very small trace of divine water.

With the change of Tong Yu's spiritual mind, this mist also slowly floated up, leaving Tong Yu's dantian, entering his meridians, and began to circulate in his body.

His body temperature had dropped a little because of the fog, and his whole body was tinged with a chill.

But maybe it's because he's a water spirit now, and he also has a strong ability to adapt to water mist, so he didn't have any major discomfort in his body.

After the pale black mist had been circulating in his body for a week, he returned to the dantian, and at this time the mist was much stronger than it was at the beginning.

But when he returned to the sky above the Sword Washing Pool, he came into contact with the divine water in the pool, and the mist suddenly shrank, just a little bigger than at the beginning.

The mist is the vitality that the water source has cultivated.

To cultivate the Yuan Realm, you need to fill your body with vitality, and in the cultivation of the Water Source Sutra, it is to fill your dantian and meridians with the mist of the cultivated gods.

When there is enough misty mist, then the mist will condense into clouds and enter the refining realm.

When the clouds turn into rain, then you enter the Lock Yuan Realm.

Tong Yu didn't seem to care about the changes in his body at all, and was immersed in the cultivation of spiritual thoughts.

The cultivation of the misty mist is meant to be the first, the spiritual power is the mainstay, and the cultivation of the vitality is driven.

The mist vitality in his body slowly grew stronger during his cultivation.

I don't know how long it took, but I felt that the cold in my body was too strong, and there were signs that I couldn't bear it, so Tong Yu stopped cultivating.

When he opened his eyes, there was a chill in his gaze, which was naturally formed.

The spiritual power cultivation mist unconsciously also brought the characteristics of the strange cold in the divine water, making his whole person with an invisible chill.

After finishing this cultivation, Tong Yu, under the escort of Cao Binfu, went back to Lingao Island, and after ordering some things, he went to retreat and practice in the Flying Immortal Cave.

Although Lingao Island is also a treasure land for cultivation, it is much inferior to the Flying Immortal Cave, and the Heaven and Earth Yuan Qi in the Flying Immortal Cave has a trace of immortal energy.

Now that the two exercises of the Water Source Sutra and the Tongtian Sword have been mastered, and the foundation building treasure washing sword pool is also available, Tong Yu can say that there is no shortage of anything in practice.

There was only one thing he had to do, and that was to retreat and practice.

A year flies!
