The chatter with Ren Fu and the three of them gave Tong Yu a deeper understanding of Feixianmen.

The true disciples in the Flying Immortal Sect are now in a state of lack of success.

The older generation of disciples abdicated, and although He Yihong and Shen Yidao had a reputation as geniuses, neither of them had really grown up, and they had not yet reached the realm of Ren Fujiao, Su Weichen and others.

Therefore, in the battle of the Burial Immortal Valley with the True Demon Palace, the true disciples of the Flying Immortal Gate suffered a big loss with fewer enemies, and even one true disciple fell directly.

And inside the Flying Immortal Gate, it is not a group of harmony that Tong Yu has seen, and there are definitely not a few disputes in the dark.

Inside the True Demon Palace was a secret battle between the five major families and other veins, while the Flying Immortal Gate was an open and secret battle between the Three Immortal Pavilion and the other four Pavilions.

Ren Fujiao, Su Weichen, and Bai Xianrong were all true disciples of the other four pavilions, and after Tong Yu entered Tongtian Pavilion, he was also in the same camp as them.

The three of them came to visit Tong Yu together, and they may not have the intention of making friends in advance.

Tong Yu chatted with them for a long time before they said goodbye and left.

When parting, they each gave Tong Yu a meeting gift.

Tong Yu sat on Lingao Island, and he was soft on the one hand, but he never forgot to practice.

There is no news about the foundation building treasure that Cai Zijing has refined for him, and he can't practice Qi refining.

However, the cultivation of the Blood Drop Sutra has never stopped, and the cultivation of the Blood Secret Technique has been re-cultivated, and the progress has been broken fast.

At the same time, comprehending the Five Aggregate Transformation Spiritual Technique from the Five-Colored Strange Flowers also gave him a lot of gains.

However, he put more energy into the understanding of the Water Source Sutra.

Tong Yu attaches great importance to this immortal scripture, which is one of the foundations of his future practice after all.

He didn't have too much ambition, but devoted himself to understanding the part of the Water Source Sutra about forging a Dao foundation, which was related to whether he could cast a flawless Dao foundation.

The way in which the Water Source Sutra forged the Dao Foundation was very different from the Five Thunder Righteous Methods he had practiced before, and it was even more completely different from any of the methods he knew.

Fog ** Snow Ice needs to go through these five forms, so that the cultivated Yuan Qi can be transformed at will in the fog ** Snow and Ice, and finally turn into fundamental water.

Fog, snow and ice are essentially transformed by water, returning to the origin, and being able to use water to transform these five forms, so as to cast a complete Dao foundation.

When Tong Yu first saw the description in the Water Source Sutra, his heart really shook.

The Water Source Sutra does not stick to water, but starts from the essence, including different forms of water, and the foothold of cultivation is significantly higher than that of ordinary water attribute exercises, which is worthy of the name of the Immortal Sutra.

"Apprentice, for the teacher, I have refined the foundation building treasure for you. ”

On the tenth day after Cai Zijing's departure, he came to Lingao Island.

Tong Yu was overjoyed when he heard this, and when he hurried out, he happened to see Cai Zijing who came excitedly.

"Master, where is the foundation building treasure?"

He had been looking forward to the foundation-building treasure that Cai Zijing had refined for him.

"Don't worry, let's go inside. ”

Cai Zijing smiled and entered the cultivation retreat room on Lingao Island with Tong Yu.

Then, he took out something and said, "This is it, you see." ”

In Cai Zijing's hand, something the size of a baby's fist suddenly appeared, and as soon as it appeared, the temperature of the entire quiet room dropped suddenly, exuding a piercing killing aura and chill.

Tong Yu shuddered involuntarily before taking a serious look at this treasure.

The whole body of the treasure is silvery-white, like a small pool, but the pool is in the shape of a sword, and an ice-blue flame in the pool is burning quietly.

Although the silver-white pool is not large, it is extremely exquisite, and there are runes carved inside and outside, and the meaning of slaughter is emanating from the pool.

Tong Yu stared at the silver-white pool for a long time, and his eyes felt a tingling.

And the ice-blue flame, although it looked like fire, was like a liquid burning, flowing, and a bone-chilling chill came from it.

"Master, what is this?"

Tong Yu liked this treasure very much, and it looked very exquisite, but he didn't fully understand where the mystery of this foundation-building treasure was.

"Haha!"

Cai Zijing smiled proudly, held this treasure, and said proudly: "This is the Sword Washing Pool!"

"Don't look at this thing, it's not big, but the whole body of the sword washing pool is made of Taibai essence gold, and it was not easy for the teacher to get this piece of immortal gold from inside the door. ”

Speaking of this, Cai Zijing's face also had a look of pain.

"Immortal gold?"

Tong Yu's eyes widened suddenly, and he exclaimed, "This is an immortal material?"

"Hey, that's good. ”

Cai Zijing squinted his eyes and said: "This is the immortal gold that can be used to refine immortal weapons, there is such a little stored in the door, of course it is not enough to refine immortal weapons, but it is just right to use it for you to sacrifice and build a foundation treasure." ”

Tong Yu suddenly had nothing to say, Cai Zijing and Feixianmen really invested for him, and even such a precious immortal gold could be taken out.

"In this pool, don't look like a flame, it's actually Hanyi spiritual water, a top-notch spiritual water. ”

Cai Zijing then introduced the ice-blue flame and said: "Since you want to practice the sword, how can you not have water and fire to quench the edge, although the cold spirit water is spiritual water, it also has the characteristics of flames, and it can be said to be the top spirit treasure for refining the sword edge." ”

"The sword qi you have cultivated, after being refined by the cold spirit water, the power must be at least three points stronger. ”

After a pause, Cai Zijing said regretfully: "The only pity is that although the Hanyi spiritual water is also good, it is not Tianshui, and it cannot reach the level of immortal treasure, and it is inferior to the sword pool refined by Taibai Jingjin." ”

"It's just that I can't match this better spiritual water in the Flying Immortal Sect, and with your water spirit body, it can also make up for the shortcomings. ”

Tong Yu has no disappointment or regret about this, Feixianmen does not, but he has!

Xuanming True Water is divine water, far more powerful than ordinary heavenly water, which is also one of the main reasons why he made up his mind to cultivate the Water Source Sutra.

"Apprentice, I will help you refine the Sword Washing Pond as the foundation of your cultivation. ”

Cai Zijing ingested Tong Yu's essence and blood, turned it into the sword washing pool, helped Tong Yu to preliminarily refined, connected the qi and machine, and then put this treasure into his dantian.

Tong Yu immediately sensed the existence of the sword washing pool in the dantian, and wisps of sharp and cold aura began to seep into his body.

But this aura was very gentle, and it did not cause any damage to his dantian and physical body, but instead nourished his physical body.

Perhaps because of the water spirit body, the breath emitted by the cold spirit water made him feel very comfortable, and his body was refreshed.

"Thank you, Master. ”

Tong Yu solemnly thanked Cai Zijing, but he was quite ashamed in his heart.

Cai Zijing really had nothing to say to him, and spending such a large amount of money to refine this sword washing pool for him made Tong Yu feel very complicated and uneasy.

"Haha, between you and me, you don't have to be polite. ”

Cai Zijing said happily: "The Sword Washing Pool has been cultivated for you, you can also start cultivating, now follow me back to Tongtian Peak!"

"If you want to cultivate the Tongtian Sword, you'd better directly refer to the inheritance left by the Tongtian Patriarch, so that there won't be any deviation. ”

Tong Yu's heart couldn't help but feel excited, as a top-level spell that was not weaker than immortal arts, he was about to start cultivating so easily.

Without saying a word, Tong Yu immediately nodded in response.

Jinshui initiate, using gold to produce water, he needs to cultivate the Heavenly Sword first, and then cultivate the Water Source Sutra.

On the way back, Cai Zijing explained everything about the Tongtian Sword to Tong Yu in detail for the first time.

"The sword of the heavenly spell is not a sword technique, a sword way, but a spell. ”

Cai Zijing's first sentence shocked Tong Yu.

"Not swordsmanship?"

Tong Yu opened his mouth wide and asked in disbelief.

"Haha, of course it's not swordsmanship. ”

Cai Zijing laughed out loud and said proudly: "Although the Tongtian Sword is named after a sword, it is essentially a spell. ”

"The magic sword, the magic sword, the law is the foundation, the sword, is just the external form. ”

Under Cai Zijing's narration, Tong Yucai had a correct understanding of the Tongtian Magic Sword.

Although this supernatural power cultivates the magic sword and also cultivates the sword qi, it seems to be the same as the way of the sword, but in fact it is very different and fundamentally different.

This surprised him and made him more and more curious.

After taking Tong Yu back to Tongtian Peak, Cai Zijing activated the ban and took him directly to the forbidden land of Tongtian Pavilion.

This is a secret place with its own space, and Tong Yu doesn't know where it is hidden.

But even if Cai Zijing is the master of Tongtian Pavilion, he has also paused several times, opening the corresponding prohibitions one by one, and Tong Yu also took out his true inheritance token to show his identity, before he came to the depths of the secret land, the inheritance place of the Tongtian Dao people.

In front of the two closed stone doors, an old man with a withered demeanor sat cross-legged with his eyes closed.

After Cai Zijing arrived with Tong Yu, he solemnly bowed to the old man's side, and said, "Uncle Li, I will bring the true disciples of Tongtian Pavilion to participate in the Tongtian Sword. ”

Hearing this, the old man slowly opened his eyes, and after glancing at Cai Zijing, his gaze fell on Tong Yu.

His gaze was like two sharp swords, which could penetrate Tong Yu's mind, as if all his secrets were hidden in his eyes.

Tong Yu's heart was cold, he didn't dare to be careless, abandoned many distracting thoughts, and guarded his mind.

The old man surnamed Li looked at Tong Yu and raised his eyebrows, and said suspiciously: "He is the true disciple of my Tongtian Pavilion generation, and he has not cultivated yet?"

"Uncle Shi doesn't know that Lan Zhuo is the new peerless genius of my Tongtian Pavilion. ”

Cai Zijing quickly talked about how Tong Yu got started, how he got the blessing of the patriarch, and how he got the Water Source Sutra and Liyuan River in the Xianyuan Cave.

When the old man surnamed Li heard Cai Zijing's story, his eyes when he looked at Tong Yu also changed, and he was much kinder, and he nodded unconsciously.

"Zijing, you finally found a good heir this time. ”

The old man surnamed Li praised two sentences and said, "Since this is the case, then let him in!"

"He has never cultivated any sword cultivation method, and he directly participated in the Heavenly Law Sword, although the harvest is definitely not big, but the path of cultivation in the future will not deviate. ”

Cai Zijing also nodded and said, "It is precisely because of this that I brought him here, let him realize the Tao first, and then teach the Fa." ”

The old man surnamed Li didn't say anything more, he personally opened the two stone doors behind him, and motioned to Tong Yu: "Go in, do what you can, and exit when you can't hold on, don't force it." ”

"The juniors understand. ”

Tong Yu's heart beat faster, took a deep breath, and strode into the door.
