The Jade Void Cave, as the preferred place for the retreat of all the core figures of Quanzhen, can be imagined to be heavily guarded. But Su Zhihang knows very well that when a person's strength reaches a certain level, the impenetrable cordon in the eyes of ordinary people becomes nothing.

Take Su Zhihang himself as an example, in the entire Zhongnan Mountain, maybe only the seven sons of Quanzhen will go out together and guard around the Jade Void Cave wholeheartedly, I am afraid that they can hinder Su Zhihang a little bit, but the effect will stop there. As long as there is no master of the same level, this obstacle will not make any difference.

And at this time, in the Jade Void Cave, everything seemed to be frozen, I saw Su Zhihang's whole body tense and motionless, the Dinghang Sword in his hand was ready to strike, ready to strike a thunderbolt at any time, in the entire Jade Void Cave, except for Su Zhihang's seemingly nonexistent breathing sound, there was no sound, which can be called a falling needle!

However, after a while, Su Zhihang's inquiry still did not show any sign of response, and the Empty Ming Heart Sutra had already been running at full strength, and the entire Jade Void Cave had been repeatedly probed several times. However, to Su Zhihang's disappointment, the Empty Mind Sutra that had been tried and tested in the past did not find any abnormalities.

Although it seemed to be just a false alarm, Su Zhihang did not dare to relax in the slightest, and still maintained a posture of being ready to shoot at any time, and asked again: "Who is here?" Please show up! ”

But as time passed, the question was still in vain, and nothing happened. In the following time, no matter how Su Zhihang tried it, he didn't get any response, everything seemed to be Su Zhihang's own words.

Of course, it is definitely not because Su Zhihang has gone crazy that he hallucinates and thinks that there is a strong enemy on his side. Su Zhihang's reaction as if facing a great enemy, in the final analysis, was only for one thing: that is, Fang Cai, Su Zhihang's Dao heart warned for the first time!

Yes, it's a Dao Heart Warning, and it's not an ordinary Warning, it's the highest level of Dao Heart Warning! At the moment when Su Zhihang was about to write out the Guiyuan Heart Formula, an unprecedented sense of horror suddenly swept through Su Zhihang's heart, and Su Zhihang's Dao Heart, which had always been unwavering, also sounded at the same time!

Although that terrifying feeling was just a fleeting illusion, but since he cultivated the Dao, Su Zhihang certainly wouldn't think that his Dao heart had an illusion. Although it is incredible, Su Zhihang is very sure that he has definitely experienced a life-and-death situation, so it is not difficult to understand Su Zhihang's performance as if he was facing a great enemy now.

Since the Dao Heart warning can't be faked, but Su Zhihang has been trying to do it for so long, although the possibility of an enemy lurking near here cannot be completely ruled out, but it doesn't look like the situation very much, so where does this life and death crisis come from? Su Zhihang died to no avail, his heart moved, and he set his eyes on the stone table.

Su Zhihang didn't dare to relax his vigilance, and slowly paced back to the stone table. The layout of the stone table is very simple, except for Su Zhihang's just-completed "Guiyuan Sword Technique", it is a set of ordinary paper and pen, and the stone table itself has already been swept countless times by Su Zhihang's Kongming Heart Sutra, of course, there is no problem at all, so next-

I saw that Su Zhihang's heart was divided into two purposes, holding a sword in his right hand to be vigilant, and a pen in his left hand, making a written statement, and then ・・・・・・ still nothing happened. Su Zhihang was not surprised, after all, "Guiyuan Sword Duel" had been completed, and if there was an abnormality, he would not have waited until now, he should have discovered it a long time ago.

Since this is the case, then the problem is obvious, Su Zhihang first wrote the words "Tao Ke Dao, very Dao" on the blank paper, and sure enough, it was still calm. After a pause, Su Zhihang continued to pick up the pen, and when he was about to write down the four words "Returning to the Yuan Heart", the sense of horror immediately came as promised!

This time, Su Zhihang, who had been prepared, did not make any drastic movements, a pen just stopped in mid-air, neither falling nor retracting, although he felt a sense of terror hitting like a tide, and a Dao heart was throbbing like an alarm clock, Su Zhihang smiled with relief.

After testing, although it was a little incredible, Su Zhihang finally found the source of the life and death crisis - "Returning to the Yuan Heart"! Whether it is written down or read out directly, as long as Su Zhihang tries to bring the "Returning to the Yuan Heart" to this world in any way, this sense of crisis will appear like a shadow.

The reason for Su Zhihang's relief is very simple, it is obvious that what brings him a sense of crisis should not be a hidden boss, because if the other party is not bug enough to fully see through his thoughts, otherwise the other party will never be able to tell what he wants to write.

If the other party is really bug to the point that he can directly read the mind without Su Zhihang being completely aware of it, then Su Zhihang will make no difference whether he says it or not, and it does not make a difference whether he writes it or not, of course, it is not ruled out that the other party wants to warn Su Zhihang not to let the "Returning to the Yuan Heart Formula" appear in the world.

However, Su Zhihang felt that as long as the other party's IQ was enough, then in the face of his monkey-like experiment back and forth, the other party should have pulled a big-eared scraper directly. Su Zhihang absolutely believes that the object that can bring him that feeling of being dead and lifeless is definitely not something that he can resist now, so this possibility is almost nothing.

After eliminating the conjectures in his heart one by one, Su Zhihang gradually approached the truth of the facts, that is, what made him almost go straight is likely to be the Heavenly Dao of this world! Of course, everyone may not react to this, so in other words, Su Zhihang's "Returning to the Yuan Heart" is jealous!

In that case, everything will fall into place. As we all know, all the treasures are born, there must be visions, and if it reaches the point that the treasures are not enough to describe, the sky is also jealous, then there will be a test, when the time comes, it is a hundred feet to go further through nature, but of course it will turn into ashes, and everything will be stopped.

What made Su Zhihang's Dao heart warn should be the test when "Guiyuan Heart Formula" was born, with Su Zhihang's strength, it was not enough to survive the catastrophe, and it was the Dao Heart that frantically warned to prevent Su Zhihang's behavior of letting "Guiyuan Heart Formula" come out. I'm afraid that only the Heavenly Dao that looks down on all living beings will not care about Su Zhihang's various forms of temptation at all.

After figuring out the cause and effect, Su Zhihang didn't know how to express his feelings, but he didn't expect that the "Returning to the Yuan" as his root had not yet reached the point of being jealous, but the "Returning to the Yuan Formula" as a derivative was reached first, and in this regard, Su Zhihang could only sigh "The world is impermanent".
