Chapter 1798: Tracing the suspect (Ⅱ)

The 5-ring spell "Bubonic Swarm" can also be used to summon bats.
1500 bats converge into a gray whirlwind, completely covering Joan.
Garu and the guards in the warehouse, aware of the invasion of a large group of bats, all changed their faces, and instinctively pulled out their sabers.
"Don't worry, these bats were summoned by me to assist in the investigation."
Joan pacified the overly tenacious stone blind barbarian warriors.
Seeing that Calu and others calmed down, Joan withdrew his sight and used "sub-mystery" to tear his consciousness in half. The main consciousness and the bat cluster established a "myth link", and the secondary consciousness focused on the 2nd ring. "Object positioning technique".
"Tuv!"
Quietly chanting a mantra symbolizing "finding", Joan applied "item positioning" to the "mother nest will" of the bat cluster through the "myth link", and then skillfully dispersed the bat into 20 small teams, Seventy-five cluster teams flew out of the warehouse one after another, conducting searches in different directions, and the target of the search was the coarse-grained bricks of standard specifications produced by the mine.
As Garu just revealed, except for a few cities with a relatively high degree of civilization, most of the ethnic groups still live a brutal life with Ru Mao drinking blood, and their industrial capacity is almost zero.
Even seemingly ordinary coarse-grained bricks require a certain degree of metallurgical industry foundation to be extracted. If a large number of standard-sized coarse-grained bricks appear on occasions that do not have an industrial foundation at all, the way forward is worth pondering.
After all, bats are mammals, and their intelligence level is much smarter than insects. As long as 15 bats can form a "mother nest will", Joan also allocated 5 more bats to each team to deal with accidental downsizing during the reconnaissance.
Joan remotely controlled 75 bat squads and started searching in different paths. Under the blessing of "item positioning", the detection radius of each squad is about 1000 feet. As long as there are large coarse-grained bricks in this area , Joan will feel.
This kind of investigative strategy has been used by Joan many times before, but no one is more difficult than this moment.
The environment of the underground world is far more complicated than the surface world, which brings many unexpected obstacles to the detection of bat clusters.
In addition, since the starting point of the investigation is located inside the mining area, and the mining area has ten warehouses dedicated to storing coarse crystals, there are also a large number of coarse crystals being processed in the smelter. These factors will cause interference in the investigation and frequent false alarms. .
Joan patiently checked out the locations of false alarms one by one until 75 bat squads were far away from the mining area.
In the following time, Joan maintained his focus on casting and patiently expanded his search.
Judging from the current clues, the theft gangs sneak into the mine every two days or so and commit crimes in such a short period of time. It can be seen that the theft gang is either lurking near the mine or someone in the gang is good at transferring spells.
Joan can only hope for the first possibility now. After all, the span of teleporting spells is too large, hundreds of miles at a time, far beyond the search radius of the bat cluster.
In the mood of suffering and loss, Joan sat in the warehouse for two hours. The search radius of the bat squad has been expanded for more than 20 miles. In addition to several false alarms, the unfortunate thing is that he often encountered lurking in the cave tunnel during the search. Monster attack.
Four teams slammed into the cobweb successively, and the echo positioning failed to help these poor little bats get rid of the disaster. They were killed by large mutant spiders. The team reduced more than 5 people, which was lower than the minimum size of forming the "mother's will". Consciousness is disconnected, which can be said to be literally "competitive."
Having searched for so long, and finding nothing except the bad news of damaging the soldiers, Joan became anxious and decided to stick with it for another hour. If he could not find a clue, he gave up and reconsidered the reconnaissance strategy.
At this moment, the "Mother's Nest Will" of the 49th squad suddenly came to telepathy, and found a large number of industrial coarse crystals that met the search criteria in a deep valley about 20 miles away from the mining area!
Joan took a breath and calmed his excitement a little, quickly switching his viewing angle to the "Mother's Will" of Bat Team No. 49.
After a moment of trance, Joan opened his eyes again and found himself above the dark valley.
He raised his hand to touch the prosthetic eye, opened "dark vision", "see through invisibility", "fog sight" and "tremor perception". After a little thought, he blessed himself with a 4-ring "perspective technique".
The penetration radius of "Perspective" is proportional to the caster's level. Counting the "mythical mana" bonus, Joan is equivalent to a 15th-level caster with a maximum perspective distance of 150 feet.
With magically enhanced vision, Joan soon noticed a cave under the cliff at the end of the valley with obvious signs of artificial excavation.
Looking through the rock wall inwards, the hole is wider than expected. In the center is a spacious hall with tables and chairs and stoves shaped by rocks. There are many honeycomb stone chambers cut around the hall, which should be local indigenous bedroom.
Joan remotely flew a bat into the cave, and followed the "item positioning technique" to fly into one of the stone chambers. Sure enough, he found two large pockets sewed by animal skin stacked against the corner of the wall.
With the help of "perspective technique", Joan can clearly see that his pockets are filled with massive coarse crystals, the size is exactly the same as the specifications produced in the mine!
In the same stone room, there are also two small humanoids talking in a low voice.
Joan listened intently, discerning that they used Tu language, but the content of the conversation had nothing to do with theft, discussing what "survival competition".
Judging from the sighing tone of these two little monsters, they seem to be full of worries about this so-called "survival race" and regard it as a disaster of infallibility.
What exactly does "survival competition" mean?
Joan restrained curiosity, and the remote-controlled bat hung upside down on the ceiling of the stone room, so as to observe the appearance of the two little guys below to find out what species they were.
However, at this moment, a "hee" sound suddenly came from below, and then a stone flew into the sky, and in the middle was a bat remotely controlled by Joan, killing it on the spot!
Damn it!
Joan's body shook, his instinctive hands covered his eyes, and he cursed in a low voice.
"Dr. Vader, don't you care?" Garoo hurried over and asked with a concerned expression.
"I'm fine."
Joan rubbed his eyes and waved his hand to signal that Garu didn't have to worry, but his face was a bit ugly.
The visually shared bat was accidentally killed and would not cause any harm to Joan himself. However, this sudden change interrupted his spellcasting concentration, and the more than 1,000 bat scouts created by the magic all resolved themselves.
