Behind the stone gate was a light curtain, and through the light curtain, Tong Yu came to a strange space.

It's a world of swords!

In the void was an endless array of transparent sword shadows, and these sword images were starry and could not be counted.

Moreover, each sword shadow is not static, but moving.

Or shuttling through the void, or dancing on its own, as if evolving sword styles, mysterious sword moves, and so on.

The sword shadows in the sky are chaotic, and there is no pattern to follow.

Tong Yu just glanced at it, and he felt dizzy, and his mind seemed to be completely filled with sword shadows in the sky, and he wanted to get lost in it.

He hurriedly closed his eyes, not daring to look again.

It was a long time before he calmed down a little before he opened his eyes again.

"Huh?"

To his surprise, the sword shadows in the void suddenly decreased by half, much sparser than before, while each sword shadow became a little larger.

But even so, it was still dense, and after Tong Yu stared at it for a while, he felt dizzy again.

He had to close his eyes again for a long time to open.

"Less?"

Tong Yu's eyes widened, and the sword shadow he saw at this moment was more than half less than before, and the sword shadow became larger again.

Although the sword shadows that remained in the void now were perhaps only one percent of the ones he had seen for the first time, there were still tens of thousands of them.

In particular, these sword shadows are still constantly changing, still giving him the feeling that the void is full of dense sword shadows.

Tong Yu's gaze was fixed on a sword shadow, watching it evolve on its own and travel through the void.

But in just a few breaths, Tong Yu was lost, several sword shadows were staggered, and he lost the trace of the sword shadow in a blink of an eye.

In other words, he didn't know if the sword shadow he continued to stare at was still the same as the original.

"Could this be the inheritance of the Heavenly Sword?"

Looking at these sword shadows, Tong Yu said blankly: "Is the inheritance of the Heavenly Sword contained in these sword shadows?

Even if the sword shadow was much less than at the beginning, with his mind and spiritual power, let alone comprehending the mysteries, it was difficult to capture the trace of a sword shadow.

"I finally understand why no one in the Tongtian Pavilion can comprehend the Tongtian Magic Sword. ”

Thinking of the starry sword shadow he saw when he first came in, Tong Yu shook his head secretly.

It was too difficult to comprehend the Heavenly Sword from such a terrifying and numerous sword shadows!

Tong Yu's excitement when he came in dissipated most of it at once.

As the first inheritance of the Tongtian Pavilion, the Tongtian Sword is not inferior to the top spells of immortal arts, and it is really not so easy to cultivate.

"Is it just for nothing?"

Tong Yu was a little unwilling, and the opportunity to get in touch with this kind of top-level inheritance can be said to be very rare.

After leaving this time, even if he was pinned on by Tsutenkaku, it would be impossible for him to come and go here at will.

He didn't know when, he would have to run away, so he definitely didn't want to waste this opportunity.

"But the problem is that I haven't practiced swordsmanship at all, and I don't know anything about swordsmanship. ”

Tong Yu smiled bitterly: "Even if there is any mystery contained in the sword shadow, I may not be able to see it." ”

Although Cai Zijing said that the Tongtian Sword was essentially a spell, seeing the sword shadow here, Tong Yu couldn't connect the Tongtian Sword with a spell at all.

All he saw was a sword!

Unwillingly, Tong Yu calmed down and continued to watch these sword shadows in the void.

This time, he didn't keep an eye on one of them, but looked at them from a large scale, trying to find out the possible patterns in these sword shadows, maybe it would be related to spells.

But after staring at the tea time, instead of having a clue, the feeling of dizziness reappeared.

He had to close his eyes, and it took a while for the tiredness in his mind to dissipate.

"Sure enough!"

When he opened his eyes, the sword shadow in the void had dissipated by more than half compared to before.

After a quick sweep, there may be only thousands left, and the sword shadow has become larger and clearer again.

Each sword shadow was closer to Tong Yu, and the changes in the sword shadow seemed to be easier to capture.

"The shadow of the sword is decreasing, maybe I really have a chance. ”

Tong Yu's heart was a little uplifted, the inheritance arrangement left by the Tongtian Dao people was extremely mysterious, but it could change according to each person's realm.

He continued to try to observe these sword shadows and comprehend the mysteries in them.

Although there are only thousands, these sword shadows are connected to each other, and they are constantly evolving.

Tong Yu tried to explore the whole picture, but still found nothing, and soon he gave up and stared at one of the sword shadows instead.

This time it didn't take as much as it did before, but it didn't last long.

In less than half a pillar of incense, he was exhausted, he just blinked his eyes, and the sword shadow disappeared.

"Alas!"

Tong Yu couldn't help but sigh and shook his head.

Closing his eyes, a tired look appeared on his face.

The exhaustion of his mind one after another made him feel quite tired.

"Am I not good enough?" or am I not talented enough?"

The continuous failures made Tong Yu doubt himself.

Is it that although my qualifications have changed, my understanding and mind are still the same as before?

Tong Yu fell into deep thought, he also knew that this kind of thought was unacceptable, but he couldn't help but think so.

"No, the Heavenly Sword has never really comprehended so many strong geniuses in the Heavenly Pavilion, and it's normal that I can't learn it. ”

Tong Yu secretly comforted himself in his heart, and said: "Even if there is no Heavenly Sword and there is a water source, it is enough!"

After pausing for a while, Tong Yu opened his eyes again.

The sword shadows in the void had once again decreased by more than half, to only hundreds.

Looking at these hundreds of sword shadows, Tong Yu's heart suddenly swelled with realization: "This is the last change!"

Even if his mind was exhausted and he closed his eyes and opened them again, the sword shadow would still be so much.

This was his last chance, if he couldn't comprehend a little mystery of the Heavenly Sword from these hundreds of sword shadows, then he would really have to return in vain this time.

He didn't take the liberty of looking at the Void Sword Shadow again, but took out the lotus seed that the Red Lotus Demon King had given him and closed his eyes again.

The lotus seed calmed his heart, all his troubles left him temporarily, and the fatigue in his mind disappeared little by little.

He just stood there silently, until there was no distraction in his heart, and then he opened his eyes suddenly.

Two faint golden rays of light shot out from his eyes, and his originally dark eyes suddenly turned into purple and golden eyes.

At this moment, he ventured to exert the power of the Tong bloodline.

Everything in the void was suddenly different in his eyes, and the hundreds of sword shadows in his eyes before seemed to him hundreds of sword-shaped runes at this moment.

And the starry sword shadow that had disappeared also reappeared in his eyes, but it was a lighter sword talisman.

"That's exactly what happened!"

At this moment, Tong Yu showed a look of enlightenment on his face.

No wonder Cai Zijing would say that the Tongtian Sword is essentially a spell, and it turns out that it is based on sword talismans.

Knowing this, Tong Yu was not much easier.

The changes in the sky sword runes were still not something he could see, and in his eyes, these sword runes were also related to each other, and the changes were so complex that even if he looked at them with purple eyes and golden pupils, he was only dizzy.

Fortunately, he was well aware of his abilities, and he shifted his gaze back to the clearest hundreds of sword-shaped runes.

His gaze casually fell on one of the sword runes, and then he stared at it intently.

Under the purple eyes and golden pupils, it was no longer the change of the chaotic sword shadow he had seen before, but the process of this rune being built into a sword shape.

From the initial bit of qi associated with other sword runes, to the appearance of the outline of this rune, it finally formed a sword shape and turned into a complete sword rune.

The whole process, all the changes, are clearly presented in Tong Yu's eyes.

When the sword rune is formed, it gradually dissolves in the mutual evolution with other sword runes, turns into a little qi again, and re-evolves into a sword rune.

Tong Yu's mind was all on this sword talisman, completely forgetting everything else.

When the entire evolution process of the sword talisman was repeated three times, two places in his body suddenly jumped.

One is in his right lung, and the other is the sword-washing pool in the dantian.

A little qi appeared out of thin air in his right lung, following an unknown route, and quickly circulated in his body.

And on the dantian sword washing pool, there was a rune flashing, as if it was in harmony with the sword rune in the void.

A trace of the essence gold qi transformed by the white essence gold flowed out from the sword washing pool, went up from his dantian, and traveled in his meridians.

Tong Yu sensed the appearance of these two qi machines, but he ignored them and still put all his mind on the sword talisman.

It didn't take long for the right lung and the two qi machines on the sword washing pool to meet in Tong Yu's body, and the strange thing was that the two qi machines fused together without any conflict with each other.

After the fusion of the two qi engines, they grew a little stronger, and some changes also occurred, and then they continued to circulate in Tong Yu's body.

The place where the sword washing pool and Tong Yu's right lung qi machine appeared, it was like the beginning and the end point, and the qi machine connected the two places together.

When the fused qi machine ran in Tong Yu's body for a week, a complete Yuan Qi, or an unformed sword qi, was formed in his dantian.

After this Yuan Qi appeared, following the route of the Qi Machine, it had to pass through the rune on the Sword Washing Pool, which inevitably entered the Sword Washing Pool.

As soon as the Yuan Qi entered the Sword Washing Pool, it alarmed the ice-blue flame, the Han Yi Spiritual Water, and the spiritual water flowed, like a flame beating, and immediately submerged that Yuan Qi.

The vitality slowed down suddenly in the cold spirit water, and at the same time shrank a little, and it was tempered by the cold spirit water for the first time.

Following the qi machine to the rune on the sword washing pool, the vitality and the rune blended, and the pure gold qi of the sword washing pool made this vitality stronger again.

Then, the Yuan Qi left the Sword Washing Pool and began to operate in Tong Yu's body again, passing through the place where the Qi appeared in his right lung.

In this complete process, the role of the sword washing pool as a foundation building treasure is vividly embodied!
