Zhi Lingqi analyzed and analyzed at this time, and they all thought that this was an incredible thing, but in the end, they only came up with four possible reasons: First, in terms of Lao Tzu's cultivation realm, this small part of the water source spirit did not have much effect on him.

For this reason, he didn't take away the water source spirit, but only washed the pill he had refined next to the water source spirit, and after analyzing this possibility, Zhi Lingqi felt that there should be about thirty percent of the proportion, which was the reason.

The second reason may be that at that time, this small portion of the water source spirit had not fully grown to the level of the Chaos Water Source Spirit, just like the original Chaos Zijin, it was still in the recovery growth period, so there was no need for Lao Tzu to take it away.

The third reason is the least likely, which should account for less than one percent, that is, Lao Tzu did not discover the existence of the chaotic water source spirit at all, but he sensed that the water spirit power here is relatively abundant, so he made alchemy and cleansing pills here.

The fourth reason is the most likely, that is, when Lao Tzu left after refining the pill, considering that if Hongze Lake did not have this chaotic water source spirit, it would most likely lead to the depletion of the local water source, turning the original fertile granary into a wasteland.

This situation is for a virtuous person like Lao Tzu, he will never do anything that harms others and benefits himself, if there is such a possibility, Zhi Lingqi believes that Lao Tzu gave up taking away the chaotic water source spirit, which is the biggest reason.

Now that he has melted this Chaos Water Source Spirit, it may lead to the depletion of the local water source, but the Spirit Spirit Qi will not have any worries at all, and with the current science and technology of the human world, these small problems can be easily solved.

After quickly analyzing these previous doubts and incomprehensions, Zhi Lingqi didn't want to dwell too much on these problems, because in front of Laozi Mountain, he still had no place to explore, so he had to hurry up.

Restarting the exploration, Zhi Lingqi did not let go of the exploration of the Washing Pill Pond and its surroundings because he had already gained something in this Washing Pill Pool, but continued to start from the place where the previous exploration had ended, and gradually probed in the direction of Laojun Cave.

After exploring the Laojun Cave, Zhi Lingqi explored the front and both sides of the Laojun Cave, as well as in the cave twice, but found no abnormal situation, so he turned to the back of the Laojun Cave to explore, but the first exploration still did not find any abnormalities.

The unwilling Zhi Lingqi explored the last area more carefully, and the reason why he did this was because Zhi Lingqi considered that after thousands of years of observation and exploration by people in Laojun Cave, something had already been discovered.

But according to common sense, the back of the attraction is generally easy to ignore or ignore, if there is anything valuable here, there is only a slight possibility in the rear, otherwise don't think about it.

When Zhi Lingqi explored the back of Laojun Cave for the second time, in the most ordinary rocky beach, he felt that his heavenly vision seemed to be slightly blocked, and if he wasn't particularly careful, he would definitely be ignored.

This rocky beach is a rectangular plot about two meters wide and about three meters long, and the plot is surrounded by soil or rocks, but this place is slightly different from other surfaces, not to mention that it has hindered its own heavenly vision.

This situation immediately attracted the special attention of the Supreme Spiritual Apocalypse, this should also be the attraction here, and finally let the Supreme Spiritual Enlightenment feel something, if there is no abnormality here, then today's exploration should be over.

But it was just such a slight pause, which made Zhi Lingqi feel that there should be a new discovery here, so he opened all his celestial vision sense, and compressed it all to this small plot in the form of a fan-shaped scan.

After a second round of detailed exploration and analysis, Zhi Lingqi determined that the rocks on this small plot should be a disguised illusion formation, which was somewhat similar to the "Vientiane Phantom Array" he knew, but of course the difference was relatively large.

After analyzing it for a while, Zhi Lingqi didn't find a clue, and was about to use the method of cracking the "Vientiane Phantom Array" to test the situation of this array and see if he could judge the specific type of formation, when he suddenly thought of a common-sense question.

Lao Tzu and his people attach great importance to Fuxi's gossip Yili, and they have studied it quite thoroughly, and have their own unique theoretical opinions on the yin and yang gossip.

After some consideration, Zhi Lingqi affirmed that the illusion formation here should be the Yin Yang Bagua Phantom Array, otherwise, not only would it be impossible for the formation in front of him to be so realistic, but it would also be impossible to persist for so many years.

Only the Yin and Yang Bagua Phantom Array can absorb the power of the Sun and Moon Essence at all times and replenish the supporting energy of the formation at any time, otherwise in this human realm where there is almost no spiritual power, thousands of years later, other Phantom Arrays have long lost their effectiveness.

With a decisive inference, Zhi Lingqi began to use the formation knowledge he knew to start cracking this Yin Yang Bagua Phantom Array, fortunately, in his previous life, Zhi Lingqi had also read some books on gossip and Yili in his spare time.

Combined with all his existing memories, Zhi Lingqi also spent a lot of effort to unlock the phantom array here, and entered a small crypt about more than 100 meters long, although it was an underground cave, but the cave was very dry.

The dryness in the cave should have nothing to do with the Yin and Yang Bagua Phantom Array on the ground at the entrance of the cave, and Zhi Lingqi saw that the cave walls, cave roofs, and ground in the crypt cave were all marked by some lines and symbols that he had never seen before.

Since he had never seen it, he naturally didn't know what these line runes represented, but he knew that this should be the real Laojun Cave, and the Laojun Cave that people discovered earlier should be a fake cave set up by Lao Tzu.

After carefully studying those lines and runes for a quarter of an hour, Zhi Lingqi did not continue to study them when he still didn't feel that he had gained anything, but Zhi Lingqi guessed that these lines and runes must have controlled the temperature and humidity in the cave.

Instead of continuing to study the runes, the Spiritual Revelation focused on the details of the cave. Although there is an ancient vicissitudes of life in the crypt cave, there are obvious traces of human activities in it.

It stands to reason that thousands of years have passed, and the traces of human activities in it should have weathered without a trace a long time ago, but in this underground cave, it seems that there are only ten days and a half moons, except for the breath sensing is more ancient, everything is not old.

All the items in the cave are almost free of dust, which shows how powerful the runes in the cave are, and the spirit Qi sighed, but did not stop exploring the situation in the cave.

In the cave, where the naked eye could see, there were no other superfluous items except for simple stone beds, stone tables, and stone benches, and Zhi Lingqi naturally understood that this kind of short-term stagnation was too normal for a cultivator like Lao Tzu.

At the same time, Zhi Lingqi didn't believe that there were only these simple stone daily necessities here, so he stepped forward and moved one of the stone benches, but he used all his strength to move the smallest stone bench.

At this time, Zhi Lingqi naturally understood that there must be something strange in it, and with his current physical cultivation in the late stage of the ninth level of the Body Shaping Realm, it was impossible for him to not even be able to move a small stone bench, and the items in this cave should also be forbidden by the formation.

But just now, I have used the Celestial Vision Sense function with all my might, and I have carefully explored these stone objects, and I have not found anything wrong! Don't...... Could it be that there is an illusory formation here?

Zhi Lingqi carefully looked at the placement of the stone bed, stone table, stone bench, etc., and combined with the various knowledge of the formation prohibition in his memory, he carefully analyzed and deduced that this should be a disguised prohibition combining the five elements and gossip.

This kind of hybrid prohibition is somewhat similar to the Yin Yang Five Elements Array, the Three Yang Lock Forbidden Array, and the Seal Prohibition that Zhi Lingqi has been exposed to before, but each has its own different style and prohibition method, so it is very troublesome to crack.

Of course, it's not that Zhi Lingqi can't crack it, but it needs to be analyzed and cracked one by one, and it also takes a long time.

So Zhi Lingqi immediately calmed down, and spent all his energy on breaking the ban in front of him, this forbidden array this time was much more complicated than the Yin Yang Bagua Phantom Array at the entrance of the cave when he entered the crypt before.

Therefore, Zhi Lingqi had to analyze and deduce one step, so he cracked one step first, and gradually cracked it in a step-by-step manner, but fortunately, the energy supply of this prohibition was also provided by the Yin Yang Bagua Phantom Array at the entrance of the cave, so the part after breaking would not rebound.
