"Little guy, don't be nervous. Just bring us over. We will protect you."
One of the black-robed figures said in a hoarse voice.
"Yes."
Kang Shin-mu nodded and forced himself to calm down.
After all, he had seen the Heaven Enlightening Demon Dragon before and had a powerful being like the dragon as his servant. Therefore, he was not particularly panicked when facing the terrifying auras of the twelve people. He quickly calmed down.
The twelve silhouettes were slightly surprised by this.
"Little guy, you have a good temperament. You make me more confident in this operation. Hehe!"
Another black-robed old man said in an awe-inspiring manner, "Lead the way. We'll go the same way as we did the previous two times. Just remember to dig deeper into the ice road!"
"Don't worry, everyone."
Kang Shin-mu replied in a low voice.
Only now did he realize that three li was not enough to dig the ice path deeper.
Because the auras of these twelve people were too terrifying, a three li thick layer of ice would not be able to suppress or isolate them. Therefore, Jiang Shenwu was prepared to dig the ice layer to a depth of five li. That way, he would be absolutely safe. However, it would be slightly troublesome to break out of the ice.
However, with the strength of the twelve people, it would not be too difficult to break through 2.5 kilometers of ice.
Anyway, there was no need to hide when the operation was about to start. It did not matter how much of a commotion they caused.
If not for the fact that they wanted to sneak up, there was no need for Kang Shin-mu.
The Frosty North Army and the Fire Dragon Army were about equal in strength. Therefore, with Kang Shin-mu's help, they could reduce the Fire Dragon Army's losses and even win the battle.
"Now, let's go."
With that, Kang Shin-mu led the twelve black-robed figures towards the Arctic Mountain Range.
He had originally planned on using the merit he earned to exchange for a first-grade dragon martial technique. However, since he was in a hurry, he couldn't exchange for it now. All he could do was take another 100 ninth firmament demon cores from the Flame Dragon Legion.
Although they had to dig a deeper ice tunnel this time, they didn't need to hide under the ice for such a long time. Therefore, if they only needed to dig an ice tunnel, 100 Yao Cores would be enough.
Once this mission was over, not only would Kang Shin-mu obtain a massive amount of battle merit points, he would also have about fifty Heavenly Fey Beast Cores left. He could swallow them in battle in the future, saving him the trouble of hunting Heavenly Fey for Beast Cores.
As Kang Shin-mu walked alone with the twelve black-robed figures, he felt a chill.
This kind of coldness was psychological, not physical. It was like a shiver that didn't run through one's body.
If it was anyone else, they would probably be trembling as they walked. However, Jiang Shenwu was able to restrain the terror in his heart very well. He calmly led them to the Arctic Snow Mountain. Then, at a place where there was no one around, he began to dig an ice path.
Seeing Kang Shin-mu condense his devouring power and begin to dig an ice tunnel diagonally in the ice surface, the twelve of them looked at each other. Then, a few of them nodded slightly, as though they finally believed that Kang Shin-mu could lead them into an ambush silently.
Very quickly, Jiang Shenwu carved out a passageway that was long enough to accommodate the twelve figures behind him. Then, he let them sneak in and directly covered the entrance at the top of the ice passageway.
This way, the thirteen of them were completely surrounded by ice.
Kang Shin-mu was already familiar with this kind of scene. In the past month, he had spent almost all his time in this kind of scene. Therefore, even though there were more people behind him, he was not nervous. After he started to devour the ice, he became more and more familiar with the process.
After two hours, Kang Shin-mu dug to a depth of five miles!
"Little guy, we heard that you wanted to dig three miles deep. We said that we wouldn't remind you to see your reaction. We didn't expect you to really dig five miles deep. Not bad, not bad."
The hoarse voice at the beginning was heard faintly. It seemed that he was quite satisfied with Kang Shin-mu.
These words made Kang Shin-mu break out in a cold sweat.
If he had stopped after digging three miles deep, it would probably make these twelve people feel that he was not smart enough, or that he was not sensitive enough to the aura of energy.
No matter what, it was not a bad thing for Kang Shin-mu to gain the favor of these twelve people.
"Senior, you flatter me."
Kang Shin-mu lowered his voice and said humbly. Then, he started to devour the ice in front of him.
The twelve pitch-black figures followed behind Kang Shin-mu and kept moving forward in the ice tunnel. Although they were not fast, they were not in a hurry.
During this process, they constantly observed Kang Shin-mu's devouring power. However, they did not see anything special about his devouring power. It could only devour all kinds of energy and convert it into pure energy.
Soon, they lost interest in Kang Shin-mu's power. To them, the destructive power of the devouring power was too weak. It would not be of much use in battle.
However, one or two of the figures seemed to have a hint of interest in their eyes through the black robes.
However, they did not ask Kang Shin-mu anything. After all, they knew that a person's talent was a person's secret. Even if they were much more powerful than Kang Shin-mu, they were not qualified to interrogate Kang Shin-mu.
Most importantly, they knew that the Yan Dragon Emperor already knew about Kang Shin-mu's existence and seemed to think highly of him. Therefore, the twelve of them would not cause any trouble with Kang Shin-mu and did not pay much attention to Kang Shin-mu's devouring power.
Three days passed in the blink of an eye.
Within the time limit given by the Fire Dragon Army, Kang Shin-mu finally dug all the way to the designated location. Although it was deeper than before, he was sure that the Beihan Army was right above them!
"We're here."
Jiang Shenwu lowered his voice and said. Then, he retracted his devouring power and stopped devouring the layer of ice in front of him.
He took out a Heavenly Demon Elixir and began to devour the energy within it to ease his hunger.
As for the twelve people's food, they would naturally take care of it themselves. There was no need for Kang Shin-mu to worry about them. Otherwise, 100 Heavenly Demon Elixirs might not be enough. If Kang Shin-mu still wanted to devour the energy of the Elixir and transfer it to them, they would not be able to ease their hunger easily.
After all, the more powerful a Dragon Martial Artist was, the more energy he needed to maintain his body.
"Then let's wait for the signal."
The old man also said in a low voice. Then, he leaned against the ice wall behind him, as if he was on guard against something.
Kang Shin-mu knew that they were waiting for the signal from above before they could take action.
This move could be called "Inside Attack and Outside Attack." However, this "inside" was different from ordinary "inside."
