Shi An successfully entered the ninth layer, and this time it only took five months.

One of the reasons for the short use of time was that the time he spent on cultivation had returned to eight hours a day, but more importantly, the surprise that Mu Linggen had brought him.

As Shi An expected, after cultivating to the eighth layer, the wood spirit root gradually matured, and absorbed a lot less water aura for nourishment, about twice as much, so that it originally needed one hundred and twenty-eight to advance, but in fact, only ninety-six were used, and the promotion time was naturally much earlier.

Because there are no new spells that can be learned during the Qi refining period, Shi An has continuously strengthened the speed and power of the water arrows and water arrow groups, especially the divine consciousness has been split into sixteen, and it can be interspersed with sixteen water arrows that can change lines in multiple clusters of direct-flying water arrows, forming a more terrifying "water arrow net".

For more than half a month, he figured out several sets of attack tactics that would coordinate and convert water arrows, water arrow groups, and water arrow nets, and planned to cultivate for a while before finding an opportunity to go to the southern vein to see if he could find an opponent suitable for him to practice spell combat.

There are often demon beasts coming over from the southern vein, but they are all just the flame eagle. Every ten days and a half months, Shi An can always see it flying from the south vein across the Tuotuo River to the north vein. Because he was defeated by his own subordinates, he didn't plan to attack Yan Ying again. Since it was an acquaintance, every time it swept over the rooftop, Shi An always waved to it politely. In reply, Yan Ying also chirped at himself as if in reply.

What puzzled Shi An was that every time Yan Ying swept over the rooftop for an hour or two, he would fly back with some injuries, and then fly towards the southern vein without saying a word.

"Could it be that this guy is also like himself to improve his combat experience by fighting? However, he is always injured, and his opponent is also quite powerful. Shi Anxin always thought so.

Now that there are not many spirit stones in his hand, Shi An has roughly calculated that according to the wood spirit root, if the absorption amount is doubled, it will take about one hundred and twenty-eight water spirit stones to be promoted to the tenth layer. Now he only had ninety-three water spirit stones left, eleven other attribute spirit stones, twenty-nine lower-grade spirit stones, and one middle-grade spirit stone. Except for the medium-grade spirit stones that Shi An didn't want to use, there were a total of one hundred and thirty-three spirit stones available. Although the number of water spirit stones was not enough, thinking that the Spirit Gathering Array also had a "Spirit Turning Array" that could adjust the aura attributes, he was not too worried about his cultivation needs, so he started a new round of cultivation with enough spirit.

But the process of advancing to the tenth layer was not smooth, so that Shi An had to give up after half a year, and the root cause was the shortage of spirit stones.

Needless to say, the Water Spirit Stone can be used directly, so the first five months of cultivation were very smooth, and looking at the speed at which the spiritual mist was generated and reduced, there was no problem with his prior estimates. But when the Water Spirit Stone was about to run out and he was about to run the "Spirit Turning Array", Shi An realized that he was wrong, completely wrong.

There is nothing wrong with the fact that the spirit stones of other attributes and the other spiritual qi in the lower grade spirit stones can be transformed into water spiritual qi by the spirit transformation array, but the conversion efficiency surprised Shi An, it was not a one-to-one conversion that he had originally guessed, but two to one. For example, ten percent of the gold aura can only be converted into about fifty percent of the water aura, so eleven attribute spirit stones are equivalent to five and a half water spirit stones at most, and twenty-nine low-grade spirit stones, and after removing one-fifth of the water spirit qi, it is only equivalent to about nine water spirit stones, so that only one hundred and eight water spirit stones are available when the full score is full.

Such a low conversion efficiency made Shi An want to cry without tears. To be honest, he was really a little reluctant to cultivate by transforming the spiritual energy to greatly reduce the value of the spirit stone. The long-term difficult life since entering the immortal cultivation realm has made Shi An develop the habit of comparing the whole thing, especially those wood spirit stones, rather than wasting half of them in vain, it is better to wait for the wood spirit roots to appear and absorb them all.

If he thought of another way, there were only two paths in front of him, one was to find another city to continue to accumulate water spirit stones by making magic circles, and the other was to use the abundant water aura here to cultivate.

The former path is relatively safe and secure, and it is inevitable to take it before the foundation is built. Even if you barely ascend to the tenth layer, and then cultivate to the perfection of qi refining until you build the foundation, the aura required is amazingly large, and you still need to find a city to reopen your business to accumulate spirit stones.

Which city to choose gave him a headache, from the words of Hall Master Zhan, it was not difficult to hear that there might be a war in the near future, no matter what he said, he was also a disciple of the Four Elephants, although he couldn't figure out the relationship between the Four Elephants and Wu Luobao and the Jihai Sect, but then went to the cities under the jurisdiction of the other two sects to give full play to his strengths, even if it was just to help scatter the formation, Shi Anzhong was always uncomfortable. Go to the city under the jurisdiction of the Four Elephants, and I don't know what the Four Elephants Temple will do to its own disadvantage after Yuan Guzi framed him, so he didn't dare to act rashly.

The latter path is fortunate to be able to cultivate immediately, the water aura here is extremely abundant, and the time spent on cultivation under the blessing of the Spirit Gathering Array will not be much slower than that of the Water Spirit Stone, the problem is that the mother has reminded you not to use the formation outside the Cave Heaven Stone.

"I guess I'm worried that someone will see it," Shi An thought.

Shi An weighed the pros and cons for a long time, and finally made up his mind to take the latter path.

In order to prevent anyone from being able to see it, he spent nearly half a month practicing the last volume of the "Essentials of Formation", and learned several quite complex formations such as the Concealing Array Talisman and the Shading Array Talisman. Next, it took more than half a month to carve more than 70 stone slabs before completing an intermediate high-level formation with the intermediate formation "Yan Xiang Array" as the framework and adding a number of intermediate formations, which was placed on the rooftop.

Endure the pain and put the sixteen lower-grade spirit stones into the spirit source slot, and the formation began to run. The main function of the transformed Yanxiang formation is to ensure that the formation will not leak out, and the light from the outside can penetrate the formation, but the light inside the formation is all converged. Therefore, from the outside of the formation, this place is like a void, except for some fog, the others are the same as other places.

Only then did Shi An feel at ease, dismantling the spirit gathering array in the cave stone piece by piece, and placing it properly in the Yan Xiang formation piece by piece while it was dark.

Adjust the position of the array flag of the Spirit Gathering Array, so that all its spiritual energy sources are changed to the outside world, and then put a low-grade spirit stone in the spiritual source groove, and in an instant, the Spirit Gathering Array began to operate, and the water spiritual energy outside the array was like a powerful magnet adsorption, forming a spiritual energy vortex with a radius of more than one zhang, which was directly infused into the formation. Shi An entered the formation and felt the concentration of the water aura in the array, although it was a little worse than the effect of using the water spirit stone under the blessing of the formation, it was much stronger than only cultivating with the water spirit stone.

Shi An was also quite satisfied with this, and was just about to calm down to cultivate, when he suddenly saw the wind and clouds surging directly above his head, and in just a few breaths, the clouds were thick, and the moon was suddenly covered tightly. The sound of loud thunder one after another indicates that there is a great thunder and lightning in the clouds gathering strength and preparing to chop down.

A bucket-thick golden bolt of lightning pierced the sky and struck straight here. Shi An's face turned pale with fright, and he immediately understood the reason why his mother was not allowed to place the Spirit Gathering Array outside the cave, it turned out that it was not a monk who was on guard, but this rolling thunder.

At the same time, in the dark place somewhere in the fairy world, the woman's face suddenly turned pale, tears and sweat rolled down, and she said to herself in a trembling voice: "It's over, it's over, I'm afraid you're going to fail this time, hard-working child, why are you so disobedient......?" Isn't it because I didn't make it clear? Stop the formation, you should stop the formation!"

Shi An also knew that things were not good at this moment, so he mobilized his divine sense as quickly as possible to take down the lower grade spirit stone that drove the spirit gathering array, and at the same time as he stopped, the golden lightning of the thickness of the bucket just hit the Yan Xiang formation, and the magic circle turned into powder in the blink of an eye, dissipated in the wind, and the golden lightning disappeared at the same time. Shi An said secretly, fortunately, he had prepared in advance, and this Yan Xiang Formation had resisted the lightning, otherwise the Spirit Gathering Array and himself would have been destroyed in an instant.

In fact, it wasn't until later when Shi An accepted the Thunder Tribulation in the Advanced Yuan Infant Stage that he realized that it was not the Yan Xiang Law Array that stopped the thunder and lightning from hitting the Spirit Gathering Array at all, but his own behavior of stopping the operation of the Spirit Gathering Array. At that time, the golden thunder and lightning, not to mention a small low-level formation, even the small half of the Purple County Mountain could not resist its blow.

The woman in the fairy world suddenly laughed, and said angrily: "You kid, you are quite clever, you scared your mother to death, see if you dare not listen to me in the future!" After speaking, she hid in the boundless darkness.

At this moment, in a small hall somewhere in the fairy world, a middle-aged immortal walked in quickly, and said to the brown-robed old man who was meditating with his eyes closed: "Qi Qi Immortal Monarch, the Taijia Sculpture Divine Array I monitored, there is a new situation today, the immortal weapon shows that there is a transformed array in the human world, looking at the size of the magic thunder sacrificed on the interface, it should be a horizontal formation in the Qi refining period, the formation has been destroyed by the magic lightning, and the person who set up the formation is estimated to be unable to escape the sky." Whether you send some Wu Weixian to the human world to check it out, I hereby ask you to show me. ”

The old man didn't open his eyes, and said softly: "Don't be so troublesome, it should be the inheritance of the remnants of the Han clan who have died, and it is only the cultivation of the Qi refining period, I am afraid that it has already disappeared, and it will not even be able to enter reincarnation, this is not what we need to focus on." Now the focus of the investigation is on the demon realm, just like other nether realms that have appeared in this array, just send a newcomer down to see the situation. ”

The middle-aged immortal asked, "Who do you think is good to send?"

"The Ascension Realm of the Human Realm is the Spirit Realm?"

"You remember right, the human realm is indeed among the forty-eight lower realms under the jurisdiction of the spirit realm. ”

"Then let Situ Rui take a trip, he is from the spirit world, he should be more familiar with the situation there. In addition, give him this piece of fairy slip, and he will understand how to do it. After speaking, a piece of immortal jade appeared in his hand, placed it at the ancestral aperture for a moment, and then handed it to the middle-aged lower immortal.

Xia Xian retreated and walked out of the small hall.

The old man narrowed his eyes slightly and chuckled, "The little glare of the Heavenly Syllabus Pagoda's instrument spirit, when you reach the spirit realm, you dare to claim to be the spirit king, you have been away for too long, this time you should come back and let me drive you." ”
