The worm's courage was much greater than before, and although it failed to succeed in the first blow, it felt the difference in strength, gathered momentum a little, and rushed up again.

Although Captain Knox had good strength, he didn't dare to resist anymore, so he had to take a vertical step to avoid the attack of the worms.

"How did this bug get so tough again. With a few attacks from the worms, Knox was beaten up and down, embarrassed. Even the blade in his hand was shattered by the worm's teeth.

Others naturally won't sit idly by, and they still have some confidence in dealing with a bug. However, when the weapon slashed at the worm, there was another "clanging" sound, and they realized that there really seemed to be nothing they could do about the worm.

Fortunately, there were many people and they restrained each other, but they also temporarily suppressed the attack of the worms, and there were no casualties for a while.

The worm itself does not have much intelligence, perhaps it has been cut by a blade before, and it will always be a little twisted and avoided when attacked, but with a few rounds of ineffective attacks, the range of worm evasion gradually decreases, the offensive becomes more unscrupulous, and the defensive pressure of everyone becomes more and more great.

"If it weren't for the damn thing carrying its back, I could have solved it in a few clicks. Looking at the increasingly ferocious worm, Captain Knox was still not convinced.

"This insect shell shouldn't be so tough" Viscount Eric was also full of doubts: "Not to mention the shadow worm that has just been killed, even on the back of the hydra, it is only relatively tough, and it is like a layer of iron armor now. ”

"Lord Viscount, do you think it has something to do with the mouse?" Bourcho, who was hiding on the side, had some thoughts.

"Mouse?"

"It's the rat that was devoured by the worm, and its appearance was so tough that even Captain Knox couldn't cut it with a blade. Bourcho continued.

"How is it possible, no matter how tough that mouse is, it still feels soft, I cut it with a knife, even if I can't cut its skin, but I can still hurt it" Knox, who was originally a little embarrassed by the knife, heard Bourcho mention the mouse, and immediately began to retort: "This worm is like a ring of steel rings, can't you hear such a loud sound?"

Seemingly attracted by Knox's roar, the worm turned around and attacked Knox, leaving no time to argue for a while.

"Maybe it's ......," Bourcho explained, "the skin of a mouse is so thick, and the skin of this insect is much thicker, so I don't think of iron and iron." ”

"Knox is right, the gap between the two is really a bit big" Viscount Knox, who was restraining the worm, spoke: "The hardness of the worm is too great, and although the mouse was dented at that time, it still has the softness of fur. ”

"It's ......," Bourcho was stunned, and he didn't know why.

"Lord Viscount, maybe that's the case" Areci on the side made an opinion: "Since there is a mysterious existence, it may not follow the laws we know. ”

Viscount Eric didn't speak immediately.

"Since you can't find a cause, why not try a possible cause. Looking at the increasingly ferocious steel worm, Aretz couldn't wait for the viscount to speak, and hurriedly continued.

"Yes, even if it's unreasonable, we don't have the conditions not to try. The Viscount's words revealed a sense of helplessness, "Then, we still have to find a way to hurt its interior in order to inflict enough trauma on it." ”

"This insect is covered in iron armor, and the thickness is definitely not small, and there is no way to attack its body" Knox struggled to open the monster's mouthparts and took a few steps back: "Even its mouthparts have hard sharp teeth, and even the blade can be broken." ”

At this point, the others stopped talking, and only a few "jingles" echoed in the cave.

Bourgeois, who was stunned for a while, also reacted, pulling his hair, as if thinking of something.

"If we have the right understanding, then maybe we can still hurt it," Bourcho shouted to the warring people, "whether it is parasitic on the serpent or as an independent being, it eats and excretes, there is always a place to communicate with the outside world, and the tail is most likely the weak point." ”

"You mean a knife in the back of this bug?" replied Knox, struggling to reply, the bug's attack putting a lot of pressure on him, "but if it doesn't work, I guess I'll have to get here, and you won't be better." ”

"Captain Knox, I'm a theory!" Bourcho was stabbed by Knox's second half of the sentence: "I can't hurt you." ”

However, Knox didn't have so much effort to idle, and took advantage of Viscount Erik's deliberate distraction from the worm, rushed to the tail of the worm in three or two steps, aimed at the center of the ring on the tail, and stabbed it hard.

"Poof", although there was some obstruction, the blade still pierced deep into the tail of the worm, and a stream of fishy blood sprayed out to play, spraying Knox in the face.

The worm ate in pain, and regardless of Viscount Eric, who was attacking, the opener pounced towards Knox.

Knox drew his machete and leaped backwards, sending the worm into the air. As the machete was drawn, a foul blood erupted from the tail of the worm, and a fishy smell filled the entire cave.

The insect that struck the air seemed to lose its strength and curled up into a ring, and the carapace lost its previous luster. Taking advantage of its illness to kill him, a group of people did not delay, and beckoned to the worm with their blades, although they were still tough, but they were not as good as before, and with some effort they cut several wounds on the worm's body, and saw that it was lifeless.

"Phew, I've finally solved this thing, I've been tired for half a day. Seeing that the worm was completely immobile, Knox sat down on the ground and gasped: "This smell, it's smoky!Lord Viscount, should we go back?"

After a long time of no response, Knox looked up at Viscount Eric.

Viscount Eric looked at the long-worn stone door in silence, as if thinking about something, and after a long time said in a deep voice: "This rock wall is not at all a product of nature, more like an artificially carved object. What's behind it, you say?"

"My lord, although it seems that this is true, but our position is by no means within the known territory of the Empire" Although Bourcho also thought it was strange, he still retorted: "I have heard similar rumors in various parts of the Empire, and naturally there are always magic works, not to mention, the labor and craftsmanship required to carve such a stone gate cannot be completed by one or two people. ”

"Having said that, I also know that there is something that is created by heaven and earth, but in order for us to live on the island with peace of mind in the future, this door must be opened. Viscount Eric shook his head: "We don't have a choice. ”

"Since you're going, then I have to be a pioneer" before Knox responded: "As for you, don't be afraid to run away." ”

"I'm not afraid of that. ”

"Just don't talk big. ”

"Okay, if you have the effort, you might as well see how to open this door, this door is still a bit thick. Viscount Eric stopped them with a wave of his hand.

Knox walked up, "This door looks like it's been pushed, why don't we try it first?"

"Long", before the others could catch up, the stone gate exploded inward, almost knocking Knox to the ground.

"This ...... This...... It's definitely not a natural carving!"

Behind the stone gate, a stone passage stretched into the distance, eventually disappearing into the deep darkness.

"Let's go in, we don't have a choice, life or death. ”
