Sentinel ants are one of the most common creatures in underground caves, and adult sentinel ants are the size of a wolfdog. The antennae on their heads are capable of sensing vibrations from kilometers away and are capable of recognizing hundreds of different vibration frequencies. Therefore, when a natural predator approaches, they can always detect it in advance and avoid the evil. This is also the origin of the name of the sentinel ant, but the sentinel ant is mostly seen in shallow burrows, like these big ants in front of you, appearing in the burrow about two kilometers above the ground is a rare scene.

These big ants are besieging a strange snake that Eren has slain, and the sentinel ants are very good at dividing the work. The front two are responsible for attracting the attention of the strange snake, and the left, right and rear ants are constantly attacking. They had bitten the snake to the point of blood, and finally a sentinel ant pounced on it and ripped the flesh sac off the snake's head. This was undoubtedly fatal to the strange snake, and it curled around the big ant in pain, and its powerful body continued to contract, causing the ant to make a soft sound all over its body, and finally died with the sentinel ant.

The remaining ants were happily tearing open the snake's body, ripping out the water bladder from its body accurately, and eating it cleanly. Then the ants gnaw on the corpse of the serpent, and the heroic sacrifice of their companions will eventually become food for them.

The tremors came suddenly, without warning. With the alertness of the sentinel ants, there were no signs at all. When they sensed the strong tremors, the entire cave passage was already shaking. Countless pieces of mud and powder were sprinkled from the stalagmites above, and the irregular rock shards of the mountain walls were shaken and shattered. The sentinel ants did not care to eat, and they crawled in circles restlessly, and the tremors seemed to come from all directions, which disturbed their judgment and made the big ants completely unaware of where to flee.

At this moment, one of the ants raised its head, and the two large black eyes reflected the moss-covered cave wall. The moss on the walls of the cave is peeling off, revealing the bare rock behind it that has cracked. Through a crack in the rock, a beam of light entered. It was a warm light, orange like the glow of magma flowing deep in the heart of the earth. However, the warmth turned to scorching heat in an instant, and wisps of foehn wind penetrated through the cracks in the mountain wall, causing the temperature to rise sharply in the passage where the sentinel ants were.

In the next moment, an orange flame pushed through the mountain rock, pouring into the cave like a flood, and a beautiful, but deadly, burst into the big eyes of the sentinel ants. The ants didn't even react, and in an instant they were swallowed up by the waves of fire that poured in. In the flames, there was a series of soft sounds of carapace explosions, and from time to time there flashed bright lights in the flowing fire, and these beams were extremely penetrating. In the flames, the head of a sentry ant was hit by a beam of light, and most of its head was lifted up, and it exploded as if it had been hit by a sniper rifle.

Whether it is a flame or a streamer, it is a disaster for the underground creatures in the cave at this moment. By the time the flames had subsided and the streamer had disappeared, the passage was in shambles. Large swaths of moss and ferns were burned to ashes, the green and yellow mountain walls were charred and blackened, and sentinel ants, strange snakes, and other unnamed creatures were turned into roasted corpses. They lay on the ground with the remaining flames, forming a hellish picture.

A wall burned through, and finally fell down with a thud under the spark spray. Falling into the mud that shook from the ground, a figure rolled in. He coughed lightly twice, plastering his head, face, and body. He had to raise his hand to wipe it, so under the firelight, Allen's face was full of helpless expressions.

The walls of the caves can be so thick that they are as thick as fortress armor. It can also be very thin, so thin that it can't withstand the impact of Allen and Catherine's source force, so it will be bulldozed and razed.

This time, Catherine's shot was obviously much heavier, and she almost didn't sacrifice the original ancestor projection. The elusive scorpion spear and the wide-opening snake scythe made it extremely difficult for Alan to deal with. After a few fights, he had already been shot three times and was beheaded with a sickle. If it weren't for the fact that his fighting skills have also been refining and growing these days, and with his subtle movements, Catherine's attacks have not fallen into the critical spot, otherwise he would have been lying down by now.

Even so, a few hollow gaps in the blade's armor and a wound on his waist that narrowly cut him in two reminded Eren that he was in danger at the moment. Footsteps sounded, and Catherine stepped on a piece of stone chips, scythered her left and right guns, and calmly walked in from the other side of the gap in the mountain wall. There was no trace of expression on her little face at all, only a ruthless indifference and murderous indifference.

She had already made up her mind.

Although it made her hesitate for days, she still made a decision.

And this is undoubtedly the worst situation for Allen. That means that Catherine has no reservations, if it weren't for the limited space in the cave, she couldn't withstand the toss of the original ancestor projection. I'm afraid that Catherine will release the femme fatale as soon as she appears, and with her strength of killing nearly a thousand flying horsemen of the Sword Demon Tribe in one fell swoop with her projection that day, it will not be difficult to kill Eren at all.

At most, it's just a little more troublesome.

"There's no point in resisting, it's just a waste of your time. Stand there and don't move, I promise it won't make you feel any pain. Catherine said with a blank face.

Alan stood up, a rescue aid slipping from his hand. thrust it into his leg before he said, "I don't have the habit of closing my eyes and waiting for death." ”

"What's so hard about it, no matter how hard you struggle, the ending can't be rewritten. Well, I'll give you some extra perks. Sue me, who do you want his life? When you die, I promise to send them to the same place. ”

"You're so generous." Alan threw away the needle that had been injected and said with a dry smile: "But when it comes to the enemy, I think it's better to have my own hands." ”

Catherine actually nodded: "Okay then, I respect your decision. You can fight as hard as you can, and I'll let you die like a true warrior. ”

"Thank you very much!"

The blade armor suddenly lit up with lines, and from behind Allen, a pair of wings composed of source power blades unfolded silently. With the blade as the feather, as soon as the pair of blade wings appeared, they saw the feathers on them decompose, and then shot towards Catherine like a torrential lightning. For a while, the light and shadow in the passage were dazzling.

Blade Wings has limited lethality, and is more useful for harassing opponents. Alan didn't expect to use it to retreat from the enemy, as long as Catherine was slightly distracted, it would be worth the source power consumed to activate this ability. As soon as the knife came out, Alan took the opportunity to pounce. His feet follow a completely irregular pace, sometimes fast, sometimes slow, sometimes for a short time, forming a series of dazzling movements. This kind of exercise is undoubtedly extremely physically exhausting, but the advantage is that with Catherine's eyesight and experience, it is difficult to predict the time, angle and position of Allen's approach.

Catherine had to admit that under her own pursuit, the young Beth cord was growing at an astonishing rate. If this speed can be maintained forever, it won't be long before he catches up with himself and even surpasses him!

However, there is no word "if" in Catherine's dictionary, and from the moment she makes up her mind, Alan is already a corpse.

Even though he's still alive and kicking.

The blood disappeared into a burst of red lightning in Alan's hand, and Catherine silently raised her right hand. The scorpion spear flashed out, hitting the blade of the heavy knife. The swords and guns clashed, making a piercing and sharp sound, and the collision of the source force generated a rolling thunder sound, which resounded endlessly in this passage. Alan smiled bitterly in his heart, he used the wings of the blade and the clever steps he had stolen from Catherine, but he still couldn't take the young admiral's mind a little.

Otherwise, how could Catherine be able to hit the blood with one shot?

He took a deep breath, leaving life and death behind him and concentrating only on carrying the knife. The mind gradually condensed, the turning of the wrist, the output of the source force, the angle of the blade, every detail was clearly reflected in Allen's heart. At this moment, he didn't even think about how to use the next knife, and focused on the moment with all his heart and soul.

Even Alan didn't know that the perception and experience of days of battles and moments of life and death would naturally become a part of his life at this moment. Just like the breath of a person, it is natural to breathe in and out. So in Catherine's eyes, Allen's knife had a hint of perfection, and the difference between the knife and the knife was as natural as breathing. One knife is used, which naturally includes several sets of actions, but it is completely integrated. Even if she is as strong as her, she can't force Allen to interrupt his knife path with skill alone.

At this point, the knife skill has been considered a masterpiece.

Appreciation is appreciation, but Catherine has no intention of releasing the water at all. The lines of the scorpion spear lit up, and the source power condensed like substance. The guns move like wind and thunder, and every shot. The stab must have pressed Allen's offensive back. Alan was not discouraged, and slashed one after another, like a tidal wave stacking on top of each other. The hundred-style combat skills obtained from the Blood Lion General were mastered by Allen at this moment after being tempered a lot. The knife moves are at your fingertips, and several moves are refined into one knife, and the power is instantly increased.

Especially with a strong opponent like Catherine for him to practice knives, Alan only felt that the more he made it, the happier he became, and his mind gradually fit with the heavy knife in his hand, and there was no difference between the knife and the person. Just as he was making his move, Catherine suddenly rose in momentum, and the scorpion spear in her hand stabbed three times in a lightning row. The three shots were in no particular order, and Alan only felt that they would stab him in the eyebrows, neck socket, and chest at the same time.

The landing points will be connected in a line, as precise as a miracle.

At that moment, the heavy knife could no longer be transported, and the blade wings swung with all their might, and the feathers turned by the sword slammed into the scorpion spear like moths to fire, hitting countless light and lightning fires. Alan retreated at the same time, but Catherine's spear was like a maggot possessed, and it followed closely. The scorpion spear passed through countless blades, and the three guns suddenly merged into one shot. The tip of the spear suddenly lit up with a little green light, and then the entire passage was dyed with a layer of blue light.

At the end of the gun, the blue gun has already come to Allen's chest!
