Now that Leach has made a decision, Saya can only follow.

After the two of them came to the lowest part of the "altar", Saya suddenly pointed to the central groove and said, "Leach, don't you think the shape of this groove seems a little familiar?"

Leach was still thinking about what to use to open the "altar", but when he looked closely, he saw that the shape of the groove seemed to be something he had seen somewhere, as Saya said.

"This ......," Leach hesitated, "why do I think this cross-section looks like it's similar to my black blade, Saya, what do you think?"

After Leach's reminder, Saya also reacted, the shape of the groove, wide on both sides, but there was a small triangular protrusion in the middle, which was indeed the same shape as the sword body of the black blade.

"Impossible," said Leach, though it had been confirmed, but still felt unlikely, "How can our family's heirloom weapons have anything to do with the altar here......?

Although the recent series of changes in the black blade all show the extraordinary origin of its origin, and Leach also acquiesced to this in his heart, but judging from the clothing of those people on the mural, it is obvious that it is a primitive society where human beings have just begun to reproduce.

"Don't get entangled, won't you know if you try it?" Seeing that Leach began to think crankily at the critical moment again, Saya couldn't help but urge when he was anxious to leave.

Smirking sheepishly, Leach pulled the black blade from behind his back and plunged it into the groove.

As previously judged, the shape of the groove is exactly the same as the black blade, no more than no less.

Fearing that the trap would be triggered, Leach was on guard after inserting the black blade into the groove, as did Saya. But after waiting for a long time, except for a crisp sound from the groove at the beginning, there was no movement.

"Cut, it's so grand, it turns out it's useless!" Leach pursed his lips disdainfully, "Saya, it seems that we still have to go back and continue to climb up the stone statue." ”

As he spoke, Leach pulled the black blade out of the groove.

Just as he was about to walk back, there was a sudden sound in his ears that seemed to be a water bag bursting, and the room darkened, but he could still see. Immediately afterward, there was the sound of rain clicking on the window.

Just as he was wondering what was making the noise, Saya suddenly pointed to the entrance and screamed.

Leach turned his head to look, and his scalp was numb as well.

I saw that the original gray-white ground had been completely covered by a layer of dark red, and when I looked closely, it turned out to be a worm the size of a palm, with an upside-down spike on the head, and the mouthparts were full of wriggling tentacles.

"Flame beetle!" exclaimed Leach.

In the volcanic zone in the south of the continent, there is a kind of social bug, the body is covered with a dark red carapace, once disturbed, its body will burn flames, and once this flame is stained, it cannot be extinguished, even jumping into the water can not prevent the fate of being burned, this is the so-called magic flame beetle.

But being touched by this flame will not be burned to ashes like ordinary flames, but will remove all the impurities from your body like alchemists refining medicines, leaving only the most essential part, and then be sucked by the Demon Flame Beetle.

The flame of the Demon Flame Beetle is very domineering, and even many fire-attribute demonic beasts can't ignore its threat, but fortunately, its requirements for the growth environment are very harsh, so even if it is very dangerous, as long as you don't go to the volcanic belt in the south of the continent, you don't have to care at all.

Since entering the Land of Trials, all the creatures that Leach has seen are new breeds, unheard of in the outside world, and suddenly discovering a creature he has heard of should have felt familiar, but if the subject is replaced by a demonic flame beetle, he would rather not have this familiarity.

To tell the truth, its danger aside, although the appearance of a single Demon Flame Beetle is a little hideous, it is also somewhat unusually cute, but if it is a large group of people, it can only give people goosebumps.

Because once attacked, it will stimulate its ferocity, so after Leach found out that these creatures were demonic flame beetles, he immediately took Saya and retreated to the innermost corner of the room.

Although the room is so big, even hiding in the corner will not help, but at this time, even a little more psychological comfort is good.

In a panic, the two were waiting for the final moment to come, thinking about the time to start desperately, but they unexpectedly found that the demon flame beetles that entered the room, as if they had not found the two big living people Leach and Saya, all gathered in the low-lying area where the "altar" was located.

Spread one layer on top of the other, then layer on top of each other. Soon, the not-so-deep pit was filled with demonic flame beetles.

After making sure that the Flame Beetle had no intention of coming out to deal with them for the time being, Leach and Saya boldly moved towards the exit by clinging to the wall.

It seemed like a century had passed, and by the time the two of them reached the exit, Leach's clothes were already soaked with sweat. Leach also discovered that all the glowing so-called minerals in the tunnel had cracked, and the ground was filled with a faint glowing rose-red viscous liquid.

Remembering that he had touched the things containing the Demon Flame Beetles with his hands, Leach was terrified.

Just as he was about to slip away, there was a sudden change on the side of the Demon Flame Beetle.

The room that had become dim suddenly lit up, and all the Demon Flame Beetles began to burn with crimson flames, and the place where the "altar" had been located turned into a huge torch.

In Leach's impression, the Demon Flame Beetle must be completely immune to the flames it emitted, but the situation in front of him was that the bodies of the Demon Flame Beetles slowly shrank in the flames, and although the pain was unbearable, none of the Demon Flame Beetles fled out.

Not long after, the flames were extinguished, leaving only a fist-sized drop of rose-red liquid above the altar.

The liquid slowly descended, and under the gaze of the two of them, it sank into the groove of the "altar".

Because the source of the danger has been destroyed by itself, Leach and Saya did not rush out, but stood in place and waited for the subsequent changes. If such a big battle is purely for the amusement of others, Leach will not believe what he says.

Sure enough, a moment later, the ground began to shake violently.
