The Krasli mine is large, a whole hill, with a core area of tens of thousands of square kilometers, in addition to iron ore, it is also rich in bauxite, tin, copper, gold, silver and other associated ores, and in the surrounding area, the area of associated ores and low-grade iron ore is more extensive.

The Karasli Mine is the largest iron ore mine owned by the Pei Chamber of Commerce, and has been mined for many years, and the surface layer was originally an open-pit iron ore, but now it has been almost excavated, and the deeper the hole has been dug all the way down, making it much more difficult to excavate. In order to ensure that the iron ore can be mined normally, the dwarves were also invited to guide them.

Now that the mine has been dug so deep that it is not easy to get out every bit of ore, but since the rails have been laid out, things have gotten much better. Although it has been excavated for many years, the amount of mineral deposits buried underground is already huge, and Bellena has asked someone to measure it, and now it is only one-twentieth of the mineral reserves excavated at most. It's just that the rest is all underground, and it's much more difficult to excavate.

But the most attractive thing about the Krasli mine is not the reserves, but the grade of the ore, which has an average iron content of about 60%, which is not common and can be smelted into higher quality steel, so the Pei Chamber of Commerce has been increasing the mine's mining capacity.

Unexpectedly, something happened in the mine this time, and even Bellena was injured.

Kaichi and Queenie walked towards the mine with light on their heads, and every time they passed, torches were planted in the walls of the cave, but because the men in the mine had been withdrawn, the torches were extinguished.

Beneath their feet was a long railroad track, which went deep into the ground, with no end in sight.

The caves were dug in all directions under the guidance of the dwarves, but only one main road was laid with rails, and all the iron ore mined from the branches was transported to the rails and transported by wagons on the tracks. Jiayi and they went deeper and deeper along the railroad tracks, but they didn't feel a little stuffy, and the ventilation measures were very good.

Perhaps it was too quiet in the mine, but Queenie suddenly said, "This mine is so tall, it feels over 10 feet old." How far have we gone now?"

"This must be the opinion of the dwarves, who are accustomed to living in the mines, and have always liked to make them spacious and tall. The front should be in the third stone hall, and the law enforcement team is about to reach the fifth stone hall when it is attacked. ”

The Karasli Mine is long and deep underground, and every two miles or so there is a huge stone hall of thousands of square meters, which is used for transit and storage of necessary supplies, and is also used here to feed and excrete the miners, who sometimes live here.

There are seven such stone halls, plus the various branch mines, and the tunnels, the total length is nearly 70 miles (110 kilometers), and it is more than 1 mile (1,600 meters) deep into the ground, and it is almost half the way to the third stone hall.

"Watch out. Kaichi reminded Queenie, "Belena was between the sixth and seventh halls when she was attacked, and by the time the Enforcer team was attacked, they were already in front of the fifth hall, and at this rate, they might have snuck up on us." ”

Kaichi said as he carefully observed his surroundings.

He gathered the light of the light technique, turned it into a searchlight, and shot straight ahead, sweeping in all directions, expanding his field of vision outward, and at the same time he also had a sonar in his hand, and the gathered beams were scanned in circles around him, he deliberately adjusted the accuracy, as long as there was any abnormal movement in the vicinity, it could not escape the scanning of the improved sonar.

Suddenly, there seemed to be a phantom flashing in front of him, and Kaichi and Queenie stopped at the same time and looked at each other, and Kaichi asked with some uncertainty, "Was there something just now?"

Queenie nodded: "I noticed it too, as if something did flash by." Are there any results on sonar?"

Jia Yi carefully observed the sonar, and the situation just now did not seem to be reflected in the sonar. Suddenly, he saw a dense patch of something appear on the sonar, rushing straight in his direction, so fast that it looked like a snowflake on TV.

"Something is coming. As soon as Jia reminded him, he saw a large number of bats flying over in front of him, which looked overwhelming.

Kaichi and Queenie hurriedly propped up their shields to protect themselves, but they didn't expect the bats to fly out entirely, some of them flew outside, but some of them lay directly on top of Kaichi and their shields and began to gnaw on the shields.

Under the gnawing of these bats, the shield began to weaken visibly to the naked eye, and even looked like it was about to break. Kaichi hurriedly added another layer of shield and reminded Queenie: "These bats have the ability to break demons, be careful." ”

I saw that Queenie's suddenly appeared a wall of fire outward, burning a large part of the surrounding bats, and then she attached a layer of ice shield in front of her, and the physical shield was more resistant to the bite of the bats, but there were still many bats around the edge of the shield and attached to the inner magic shield to bite.

These bats have hideous expressions, and the front teeth on their mouths protrude forward, looking like sharp-nosed pliers, and with each bite, a piece of energy is missing from the shield. Jia Yi stretched the sonar in his hand forward and reminded Queenie next to him: "Be careful. ”

There was a sudden buzzing sound from the sonar, which made both Kaichi and Queenie feel their hearts shrink at the same time, as if they were grabbed by someone's hand, and Queenie's face turned white, and the shield almost collapsed. She stabilized her magic, and saw that the bats around her that had just fallen to the ground one after another, and even if they didn't, they couldn't help but spread out around them, past them, and flew away into the distance, and the bats that had not yet flown in front of them turned around and flew back into the depths of the cave.

When the bat left, Kaichi stopped the sonar, and his own face was a little pale and he felt a little disgusted. He just used ultrasound, which contains strong energy, and he deliberately adjusted the frequency, which can stun the bats and destroy the sonar positioning of the bats themselves, so he drove them away.

However, the lethality is also part of the enemy, and they have not been able to protect themselves from the emergency just now, so they themselves feel a little disgusted. The buzzing sound that just emitted is just a murmur diffracted by ultrasound, not the ultrasound itself.

Queenie picked up a bat and looked at it carefully, then looked up at Jiayi: "This is a vampire bat, but ordinary vampire bat teeth don't have the effect of breaking demons." ”

Jia Yi also picked one up, reached out and pulled the bat's teeth off, and the bat was stimulated and immediately walked over, struggled in his hand, and was pinched to death by him.
