Above the sky, Donghuang Yu'er has been pulled higher and higher by the overlord, and is getting closer and closer to the overlord. Her current situation can already be described as dying. Below, Huan Yin didn't look at Donghuang Yu'er again, his mind spun rapidly, and he struggled to think.

Huan Yin knew that if there was really a glimmer of hope to save Donghuang Yu'er now, then this glimmer of hope must be tied to the mysterious "Daomen". Now he can only solve the problem by finding out the Dao Gate as soon as possible, and he is worried that Donghuang Yu'er, looking around, looking left and right, will only waste time in vain.

"Daomen, what is the Dao Gate that the patriarch said, is it the Gate of the True Dao?" This is the answer that Huan Yin subconsciously thought of, and he felt that there was some truth to this answer.

After all, the Desolate Ancient is above the outer world, and if the Desolate Ancient Dao Gate appears, it means that Huan has achieved the true path and ascended to become the Desolate Ancient God. Perhaps, Huan Yin will be able to fight the overlord with his own strength!

It's just that the reason makes sense, but Huan Yin knows that it would be a fool's dream for him to become an ancient god now. Although his true path cultivation is already considered strong, it is still far from Dacheng. In this way, if the Dao Gate mentioned by the Immeasurable Venerable is really the Ancient Dao Gate, then if it is placed here in Huan Yin, wouldn't it be a dream that is impossible to realize immediately?

"No, the patriarch and his old man's life's work is the "Immeasurable True Scripture", which is not a true way, and he has not ascended to become a desolate god. So the Dao Gate he was talking about should not be the Gate of the True Dao!" Finally, Huan Yin found a reason to convince himself and rejected this idea.

What, then, would the door of truth be?

"Wait!" Suddenly, a flash of inspiration appeared in Huan Yin's mind: "Since the patriarch and his old man's life's work is the "Immeasurable True Sutra", is the 'Dao Gate' that the Patriarch said is a certain Dao Gate above the Immeasurable True Path, perhaps, it is the ultimate gate that can only be seen when this path of cultivation comes to an end?"

Thinking of this, Huan Yingang felt that he seemed to have some eyebrows, but he hesitated. Because he found that he had completed all four volumes of the Immeasurable True Sutra and all three volumes of the Immeasurable Sword. The path that the Immeasurable Venerable Venerable had guided him to the end of the road, but he had not seen the so-called Dao Gate.

"Or is it that in fact, I haven't cultivated the Great Dao of the Patriarch to the extreme at all, and there may still be a fifth volume of the Infinite True Sutra!" Huan was meticulous and keen, and soon got a new idea in the way of reverse thinking. And as soon as the idea popped up, he thought it was very likely. Because the Immeasurable Venerable also had this kind of teaching, which was only inspiring, but not explicit, on the path that guided Huan Cause. For example, the third volume of "Infinite Sword" is the revelation of Huan Yin by the Immeasurable Venerable, and all of Huan Yin's own comprehension is out!

Moreover, if the Immeasurable Venerable has done this, there must be a reason for him. Let's take the third volume of "Infinite Sword" as an analogy, if this volume is not self-perceived, it will never gain much. If it is taught in plain text, I am afraid that the effect will not be good, and it is easy to limit the play of the monk himself, so that the final cultivator will have his own appearance and no charm.

So, if there is no problem with Huan Yin's thinking, what will be the fifth volume of the "Immeasurable True Sutra" that has not yet appeared? Or to be more accurate, this volume is obviously impossible to teach the Tao in plain text, how does Huan Yin need to understand it on his own?

All of a sudden, Huan Yin was confused again. Thinking that the third volume of "Infinite Sword" was also the Infinite Venerable who managed to lure him to the outer world, and he realized it. At the very least, the Immeasurable Venerable created the conditions for him, and it can be regarded as a kind of reminder for him. But now there are no hints and guidance, do you want him to feel at will?

In that case, there are too many possibilities. By the time he tried them one by one, Donghuang Yu'er had already disappeared, the entire Three Realms might be gone, and his Huan Yin had already disappeared, what else did he feel?

"No, the ancestor has always done things without leakage, but he will not leave any of the conditions that should be created for me. So, either my thinking is wrong, then the fifth volume of the Immeasurable Sutra does not exist at all. Either the patriarch's guidance is already in place, but I haven't noticed it yet!" Thinking of this, Huan Yin looked up at the sky and glanced at Donghuang Yu'er, who had turned into a little smaller, and his eyes suddenly turned red.

There is no time, and Huan Yin has no time to think about the next possibility. Therefore, he decisively chose to believe that the fifth volume of the "Immeasurable True Sutra" must exist, and continued to analyze it along this line of thought!

"What kind of guidance has appeared around me that I didn't notice?" Huan Yin looked around and saw the city of Zen that had long been in ruins, and saw countless pairs of helpless eyes, but there was nothing else.

In this situation, where did the guidance come from, where did the hint come from?

Huan Yin didn't have time to analyze too comprehensively, so in desperation, he had to continue to think according to the existing conditions: "There is no hint, does it mean that this final fifth volume does not need any hints at all, and it should be up to me to exert my own understanding." Even this volume will have different content because of everyone's different perceptions, but in the end, it will be the same way?"

Thinking of this, a flash of lightning suddenly flashed through Huan Yin's brain, and he found that he seemed to have caught something!

"The perception of self-exertion actually accompanies the life of every monk. Any monk cultivating any Dao Fa is self-perceiving, so there are thousands of Dao systems in this world, and the Dao Fa is even more strange! For me now, what I can perceive on my own is to continue to improve my cultivation, and then perceive a source force—the tenth source power!"

Thinking of this, Huan Yin was stunned by his bold idea. Because as we all know, the limit of a monk's cultivation is the Nine Sources, and I have never heard of anyone breaking through. Ten Sources, that is a realm that has never been considered, not even a realm, but something more ethereal than a dream.

However, Huan Yin was attracted by such an idea, because he found that he had the ability to obtain the Ten Sources. Because his Heaven and Earth Twin Souls were all tempered to the extreme during the Tribulation, and his Heaven and Earth Twin Souls could accommodate the ultimate Five Sources, so the Ten Sources were not a complete fantasy for him!

"Maybe it's the tenth source power, that's right! Breaking through the limit of the nine sources just caters to the word 'immeasurable' of the patriarch's Taoism, and surpasses the world's cognition. And once the Ten Sources are truly attained, then the last volume of the Immeasurable True Sutra will naturally appear. In other words, the tenth source is the fifth volume of the "Immeasurable True Sutra"! At that level, the 'Dao Gate' in the mouth of the patriarch may also be naturally opened!"

Thinking at this point, Huan Yin glanced up at the sky again. Far away in the sky, Donghuang Yu'er's figure had become extremely blurred, and he was about to lose sight of it. So he knew that he didn't have time to continue thinking and analyzing. Since he thought of this, he decided to take a gamble and try ten sources once!

If it succeeds, there may be a glimmer of hope. If it fails, the Eastern Emperor Yu'er will die and the Three Realms will be destroyed, and he will be powerless.

It's just that this tenth source is said lightly, in a hurry, where can Huan Yin find it?
