Actually, Auschin's Detection Spirit Device originally could not detect the invisible Spirit Device on Kaien.
But Auschin felt that if such an invisible Spirit Device could really evade his detection, it would essentially plant a hidden danger for him.
So Auschin upgraded his Detection Spirit Device.
After upgrading, Auschin even went to teacher Shao Xin for a test.
The final result was that as long as Shao Xin, running a full-power Anti-Detection Spirit Device, moved around within a 500-meter radius of Auschin for a while, Auschin could always detect his location.
This was also the reason Auschin had the confidence to say that as long as Flandre and Zhao Wuji used Spirit Device methods and were within 500 meters of him, he could definitely detect them.
In fact, the principle behind upgrading the Detection Spirit Device was not difficult. Since single-function detection Spirit Devices like sonar, infrared, or optical types could not find the flaws of the invisible Spirit Device,
then simply integrate them all together and put all these functions under a unified intelligent system for management.
This system could summarize all the detected information from various sources, extract the patterns, and finally produce the most probable result.
As long as Kaien, wearing the invisible Spirit Device, was still moving, he would inevitably leave behind tiny flaws.
These flaws were so minute and existed for only a fraction of a second, so they might not be noticed on the detection Spirit Device display.
Even if noticed, the human brain could hardly integrate and analyze the detection results from various Spirit Devices simultaneously and reach a conclusion.
In such matters, it was clear that a matrix-operated intelligent system was much more adept.
Therefore, although Auschin might not detect Kaien's position immediately after he went invisible, over time, the matrix algorithm of the intelligent system could help him analyze Kaien's most probable location.
As for how to make the matrix intelligent system, that had to be asked at the Omniscient Library.
As long as the item Auschin wanted to find was within the scope of Spirit Devices, he could find the schematics in the Omniscient Library.
After lunch, everyone rested for half an hour, then dismantled the surrounding detection Spirit Devices and continued forward.
Sure enough, the journey became much more difficult this time. Kaien led them past the territory of the fiery monkeys and avoided the giant needle bee hive.
However, as they proceeded along a narrow creek, they were suddenly attacked by a century-old bay crocodile lurking in the mud at the bottom.
Because it was hidden under the mud, the crocodile's presence evaded both Kaien's nose and Oscar's infrared detection Spirit Device.
Also, because the crocodile had remained still, Auschin's Detection Spirit Device failed to capture its figure.
Most importantly, given that the crocodile was nearly ten meters long, it simply shouldn't have appeared in this creek, which looked no more than two meters wide.
The seemingly shallow creek caused everyone to unconsciously lower their guard against dangers within the water, focusing their attention instead on the jungle to the right of the team.
So when the crocodile suddenly burst from the mud to attack, Ma Hongjun, who became its target, didn't react in time.
If it weren't for the trigger-based Spirit Device defensive shield on Ma Hongjun, which bought him some time,
the century-old bay crocodile's ambush could very likely have dragged Ma Hongjun directly into the mud at the bottom of the creek.
Fortunately, although the crocodile's bite force was terrifying, it still couldn't break through the Grade 3 Spirit Device defense.
As a result, the crocodile failed to bite Ma Hongjun, couldn't immediately close its jaws, and was forced to crawl completely onto the shore.
Ma Hongjun, realizing he had been ambushed without warning,
ignited his two Spirit Rings in anger. Under the amplification of his second Soul Skill, Phoenix Rebirth, the Phoenix Fire Line's power increased by 50% and shot directly into the crocodile's unprotected mouth.
The soft interior of the mouth was scorched by the Phoenix Fire. The crocodile raised its head in pain, thrashing violently in an attempt to push back Ma Hongjun and Zhu Zhuqing.
As a water-attribute Soul Beast, the Phoenix Fire Line's damage was amplified against the crocodile.
Considering the crocodile's extremely tough scales and immense strength, Ma Hongjun and Zhu Zhuqing chose to temporarily avoid the brunt of the attack.
The members of Shrek Academy retreated a short distance, forming a battle formation, but did not immediately attack the enraged century-old bay crocodile.
After all, this crocodile was not their hunting target. If it chose to leave once it regained its senses,
the group had no intention of fighting this troublesome giant, nor was there any need to kill it.
As expected, after venting for a few seconds, the crocodile did not continue attacking the students.
It glanced warily at the students, who had already revealed their Spirit Rings, then turned and crossed the creek, disappearing into the jungle on the other side.
The century-old bay crocodile was not a mindless beast. With three conspicuous purple Spirit Rings among the Shrek group, it was normal for the weaker party to retreat when clearly outmatched.
Watching the crocodile leave, Oscar teased Ma Hongjun: "Fatty, why do you think the crocodile chose you as its ambush target instead of Zhuqing? Because it thought you were easier to handle, or because you have more meat?"
"Oscar, don't get arrogant!" Ma Hongjun jumped in response.
"Obviously, it's because the aura of my Fire Phoenix threatened the crocodile, so it wanted to take me out first."
"Eh…" This was the team's reaction to the narcissistic fatty.
Rewinding slightly to when the crocodile first ambushed and the students adjusted their formation,
Auschin remained at the rear. After the formation adjustment, his position ended up almost next to the jungle on the right side of the original team.
Worried that the sounds of combat might attract other jungle Soul Beasts,
Auschin turned his body to face the jungle, back to the crocodile, and turned the Detection Spirit Device to maximum power, alert to movements in the jungle.
Being a century-class bay crocodile, Auschin was not worried it could break through his teammates' defenses and threaten his back.
In such a secure situation, the main concern was "a yellow bird behind" or "an accident in the gutter," so having a gun ready was still necessary.
Unexpectedly, Auschin's actions quickly bore fruit. Within just two seconds of full-power detection, the Spirit Device display on his faceplate suddenly showed two red dots 486 meters away.
The red dots quickly approached. Just as Auschin's right forearm sniping Spirit Device and left shoulder rapid-fire Spirit Device were about to alert the team,
the two red dots stopped 200 meters away. From the dots' height above the ground, the targets seemed to be in the treetops.
This strange behavior made Auschin suspect something.
He didn't cut off Spirit Power to the device, but also refrained from attacking rashly.
The dots remained stationary for a while, and on Auschin's display, their color gradually faded.
Before they disappeared completely, the dots began moving again, this time away from Auschin and the others.
Within about two seconds, the distance exceeded the 500-meter maximum precision of the Detection Spirit Device, and they vanished.
This strange movement confirmed Auschin's suspicion: the two red dots represented Flandre and Zhao Wuji.
They had apparently come to check on the students during the attack, realized the students could handle it, and then retreated.
"Flandre and Zhao Wuji really are more than 500 meters away," Auschin noted, a bit surprised at the two headmasters' relaxed attitude.
In his mind, he thought, "With your reaction speed, if we suddenly encountered some unstoppable danger, you definitely wouldn't have time to save us."
In the jungle, 500 meters isn't the same as 500 meters on a plain.
Even if Flandre were a Sensitive Attack-class Soul Saint, he couldn't have his attack cross 500 meters instantly.
