Although Angus persuaded in a serious tone, Jiang Yan still didn't want to give up his original plan easily.

It was not too surprising for Jiang Yan that this oasis was strange, because according to the vague sense of exploration, what he was looking for was actually in it.

Shaking his head, Jiang Yan summoned his wisdom and gave an order: "Let everyone retreat five thousand meters, and then temporarily camp on the spot." ”

The troops had set out in the morning, and now that the sun had hung directly above their heads, even if they were all elite soldiers with not weak and extraordinary strength, it was almost time to rest.

The order was quickly reached by Zhi Brain, and the troops of 5,000 people retreated in an orderly manner to a Gobi Plain five thousand meters away from the Devil's Oasis, and selected an area with open terrain and good vision as a temporary stationing position.

This distance can observe the situation on the Devil's Oasis side at any time, but it is not too close, and if something happens, there can be a certain buffer time for reaction. The line-of-sight distance of 5,000 meters is not much different from 500 meters for soldiers who have many far-sighted observation methods and can also use the sentinel of the submachine network to conduct reconnaissance like remote broadcasting.

After choosing a location, the soldiers began to assign their own work according to the command of Zhi Brain.

Ordinary soldiers began to carry the necessary cooking tools, tents, and ingredients from the shelves of the wagons, and began to light fires and cook.

The sorcerers are responsible for using earth spells to manipulate the rock and soil in the earth, creating temporary defensive walls and access gates, and compacting the soil under their feet into patches of smooth and stable regular roads that are convenient for people and animals to pass. Subsequently, he simply used the rocks extracted from the ground to build spacious and tall stone houses in the camp.

Earth-based spells represented by "Earth Manipulation" are not only highly applicable in combat, but also very useful for home travel in the wild, which is very obvious at this time. Using local materials, a small walled city that can accommodate thousands of people for a long time has been built directly on the ground on the desolate Gobi Desert.

Although the buildings in this walled stronghold are basically gray and white, cold stone because of the limited materials, and because they are military needs, they are all in a thick and rough simple style that pursues stability and defense, but this is at least a good infrastructure.

When the soldiers set up the camp, Jiang Yan left the camp alone, sitting on a snow-white giant eagle transformed into a mimic transformation of the slime Xiaobai who had not appeared for a long time, and came to the position of more than 3,000 meters above the Devil's Oasis from the air, looking down at the vast green jungle below. And the strong wind blowing at high speed around him and the chill blowing were all separated by a layer of faint silver light emitted from Jiang Yan's body, which did not affect him in the slightest.

This oasis stretching for hundreds of square kilometers, even if Jiang Yan overlooks it from a high altitude, he can't see it all at once.

As far as the eye could see, all Jiang Yan saw were lush greenery, and there was not a trace of a beast, not even a single skeleton.

Jiang Yan didn't think that this oasis had never been touched by wild animals, and that water was crucial for creatures in the desert. The river flowing in the oasis below and the huge lake in the center covering more than ten square kilometers are a great weapon to attract other creatures in this desert.

I can't see it now, but I guess not a single bone has been completely digested into fertilizer by these carnivorous plants.

Through the temptation of the sentinel composed of tens of thousands of birds and finches sent by the Zhi Brain just now, Jiang Yan has already understood that almost all the plants in this oasis are not normal, even a seemingly ordinary wild grass may be able to prey on small animals like a living thing.

After sensing the periphery of the oasis for a moment, he reached out and patted the Eagle Slime beneath him. He pointed to the lake in the center of the oasis.

Xiao Bai realized, his wide wings adjusted his body in the air with just a slight shock, and he calmly carried Jiang Yan into a white light and disappeared in place.

After Jiang Yan's cultivation progressed, Xiao Bai, who was his contract elf, also gained huge benefits because of the continuous nourishment of the contract master's full spiritual power, plus the ranch that Jiang Yan specially created for it to cultivate the 'Gluttony Factor Ration' had been built and began to produce results, Xiao Bai's cultivation had improved by leaps and bounds again in a short period of time after devouring the shadow demon clone.

Now, its strength level has grown to the level of the second and ninth orders, and it is only one step away from the third level of the legendary realm.

If he wanted to, Xiao Bai could even try to break through the barrier to the third-level legendary realm by now. It has the devouring ability of "gluttony", and it has Jiang Yan's sub-machine forces to provide rations for growth, and the accumulation has already reached the target.

But after Jiang Yan checked its state, he still decided to let Xiaobai slow down the promotion speed for the time being, because it would definitely grow a little too fast, although the qualifications for promotion had accumulated enough, but the foundation would inevitably have some vanity.

The reason is that the growth rate of Xiaobai's soul is a little unable to keep up with the current cultivation level. After all, the prey that the ration ranch that cultivates the 'gluttony factor' can provide to Xiaobai is quickly spawned by the brains using data abilities, and although the flesh and blood of these prey are rich in nutrients and spiritual power, the quality of the soul itself is not too strong. Devouring such prey, Xiaobai's soul will not get much benefit.

Jiang Yan was afraid that if Xiaobai's soul strength couldn't keep up, it might fall short if it rashly attacked the third-level barrier. So, at this time, let's let it settle for a while.

However, even if it stays at the second-level and ninth-order strength level, Xiao Bai's countless software and mimicry skills that can cope with most occasions are enough for it to be almost invincible in the circle below the third-level cultivation, and it will not become useless.

For example, now, as a mount, Xiaobai is very qualified. In less than half a minute, it flew over a distance of 10,000 meters with Jiang Yan to the top of the lake in the center of the oasis.

The lake below is as calm as a glass mirror, and only occasionally ripples in the breeze, reflecting a brilliant golden light in the sun, which looks like an ordinary lake.

But Jiang Yan looked at the lake and frowned deeply.

"Really...... The lake in the center of this oasis is also the place where the concentration of magic particles is the highest!"

Highly active magic energy particles can interfere with wide-area long-range perception ability, although such interference has little impact on Jiang Yan, there are indeed some.

Jiang Yan's usual data ability wave had already spread out silently just now, but even if he entered the sky above the oasis before, it was enough to cover the data scanning wave within a range of thousands of meters in the oasis, but after arriving above this lake, it actually began to be suppressed, and it became only able to detect intelligence information within a distance of more than 2,000 meters!

Jiang Yan's data wave detection ability itself is not a one-size-fits-all approach, some powerful enough formations or enchantments can block it, the difference is only how strong the barrier is.

'No!The interference of the magic particles is not completely ineffective for me, but it shouldn't be so large!...... Is it the work of the strange force field that looms in the oasis......?

Jiang Yan closed his eyes and silently comprehended the nature of the force field that shrouded his body, and after about ten seconds, a little surprise flashed in his open eyes.

'How does it feel...... Something similar to the force field radiation formed by some kind of geographical formation?'

Jiang Yan, who started from the rune Dao system in the Canglan Domain, and later collected the knowledge and technology of many small worlds in the vicinity through the reincarnated people sent by the Red Jade Tower, is naturally no stranger to the way of formation that occupies an important corner in the rune Dao system.

Therefore, now, he felt that the strange force field that permeated the center of this oasis was very similar to the power of the rune formation.

Jiang Yan looked at the forests and lakes below, generally speaking, the formation needs to arrange the formation base formation track, these are directly engraved somewhere in the environment, and the most likely location is the ground and underground. Jiang Yan, who was in the air, flew all the way from outside the oasis to the center of the oasis, and indeed did not find any hidden formation base formation track in the air, so it was very likely that the formation base was hidden in the jungle below or underground.

But unfortunately, after arriving at the Oasis Center, Jiang Yan's data detection ability has been suppressed to a range of more than 2,000 meters, and Jiang Yan found that this suppression will be further strengthened with the shortening of his distance from the ground!

On the one hand, this proves that the source should indeed come from the ground, and on the other hand, it also makes it impossible for Jiang Yan to easily find out the true face of the source.

The long-range wide-area exploration method was not enough, so he could only take the risk of directly closing the distance and exploring it himself.

"However, there seems to be something hidden under the lake, which gives me a faint sense ......of threat?

Then, try it a little first, can you wake it up and let it come out on its own!

After observing from a high altitude, Jiang Yan waved his hand casually, and the atmospheric spirit son in the nearby space of dozens of meters was easily absorbed by him, turning into a fist-sized, somewhat dazzling white spiritual power light ball suspended in the palm of his hand.

After the ball of light was formed, the spirit sons in the surrounding atmosphere did not stop converging on Jiang Yan's hands, but the scope of convergence continued to expand.

50 meters, 80 meters, 100 meters, 300 meters......

The spirit sons in a larger and larger range were all gathered, and even a huge spirit child vortex with a faint white glow was formed in the sky above the Devil's Oasis! And the center point of the vortex was the small ball of light that was spinning on Jiang Yan's palm.

Under the traction of Jiang Yan's strong will, which had already reached the third-level and sixth-order realm, a huge amount of spiritual power in the environment was forcibly ingested and infused into the light ball in his palm, and this method of forcibly gathering spirit seeds even drained the spirit energy within a radius of kilometers in a short period of time.

The ball of light that gathered such a huge amount of spiritual power had always maintained its original fist-sized size under the control of Jiang Yan's will, but the spiritual light it emitted had become more and more abundant, and finally it even seemed to turn into an ultra-miniature white star, illuminating the vegetation of the Devil's Oasis below with a hazy paleness.

"Hmm...... At this level, it should be just right. Looking at the wisps of light on the surface of the spiritual power ball on his palm, which had begun to faintly distort due to too strong spiritual pressure, Jiang Yan stopped compressing his spiritual power when he saw it. Then he grabbed the orb and casually threw it towards the oasis below.

After this spiritual power ball broke away from Jiang Yan's palm, it immediately erupted into terrifying spiritual power fluctuations, turning into a meteor with a blazing white surface gushing with violent spiritual power and falling towards the lake below.

As it fell, the size of the blazing white meteor swelled dramatically, starting with the size of a basketball, and in a few blinks of an eye, it skyrocketed into a small sun more than ten meters wide. Before it completely fell into the lake, the terrifying spiritual pressure emitted from the surface of the lake pressed a hemispherical puddle hundreds of meters wide.

But at this moment, an invisible repulsive force field suddenly erupted from the bottom of the lake, impacting the giant spiritual power ball that fell from the sky, and in an instant, the giant spiritual power ball that was originally falling rapidly seemed to be stuck in a quagmire, and the speed of the fall suddenly began to decrease sharply.

"Huh, in addition to interfering with detection, does it also have defensive capabilities?" Jiang Yan, who saw this scene, sneered, and then raised his hand to aim at the giant spiritual power ball below, and gently pressed his palm downward.

Suddenly, the giant spiritual power ball seemed to be pushed down from top to bottom by an invisible thug, and the falling trend that was about to stop suddenly intensified again.

Circles of huge waves swayed from the puddle, with a huge roar constantly surging towards the lake, impacting the branches of those lush trees that grew to a height of twenty or thirty meters by the lake, all of which swayed, waving their branches that were at least one meter thick, and slapping the waves composed of the diffuse lake water or directly breaking into flowers.

However, the movements of these mutant giant trees could not affect the huge spiritual power ball that was about to fall in the center of the lake at this moment, although it was slowed down by the invisible repulsion from below, it was still firmly 'pressed' into the lake by Jiang Yan in the air, and after forcibly discharging countless lake water, it smashed into the bottom of the lake.

"Boom ——!!!"

A white light that seemed to drown everything burst out from the heart of the Devil's Oasis.

The entire land within a radius of dozens of kilometers in the Devil's Oasis shook slightly, and this shock made even the thousands of soldiers who were camped outside the oasis clearly feel the tremor coming from the ground under their feet.

"That's ......"

The soldiers who sensed the direction of the epicenter immediately looked towards the oasis in the distance, and just happened to see a spectacular dust cloud mixed with thunder and lightning generated by the friction of wisps of blazing white spiritual power, which was tumbling and rising in the depths of the oasis.

At the same time, the soldiers heard a strange roar that was deep but harsh, not like a normal creature, coming from far away from that direction.
