Jumping down the edge of the big pit, about three or five meters high fell to the ground, in front of it was a tunnel that was inclined downward, Liu Xianyu looked at the tunnel, the white slime around the tunnel has begun to gradually decrease, I can't imagine how the huge monster passed through this passage, the passage is completely disproportional to its size, thinking of this, a picture of a slime drilling a hole appeared in his mind.

[These are the captain's footprints.] 】

The archer bent down and saw a row of footprints left on the ground with the magic lamp in his hand, and looked in the direction of the footprints into a deep tunnel leading to nowhere. After about five minutes of walking, the dirt under their feet began to gradually become less, and the discomfort of being one foot deep and one foot shallow was gone.

[Was this really dug up by a monster?] To be able to dig such a deep passage in just a few minutes? 】

Liu Xianyu muttered.

[So little brother, you are still too young, take a closer look at your feet and the top of your head. 】

The shooter who hit the head said to Liu Xianyu as he advanced. Listening to his words, Liu Xianyu bent down and carefully observed his feet and the top of his head, only to find that behind the dirt, something like masonry could be vaguely seen, this passage should not have been completed by the white monster in a short time, but there was originally an underground passage here, but it was blocked by soil, and the monster just cleaned up the soil in the passage.

[Could it be that there are other buildings under this cemetery?] Why is there such a medium-sized building underneath the Bellette family's cemetery? 】

Ikateris asked, puzzled.

[These are not the issues we need to care about, we just need to know how to collect money and do things, too much exploration of the owner's secrets is a big taboo for our industry. All I want now is to get to the boss and the two of them quickly and get out of this place where it's hard to breathe. 】

The mage explained nonchalantly to Ikateris.

I don't know how far the passage extended, even if it was tilted down, Liu Xianyu estimated that they were now at least more than twenty meters deep underground, and the shooter who was walking in front finally stopped.

[What's wrong?] 】

Liu Xianyu couldn't see the situation ahead because he walked at the back.

[No way...... The front was sealed. 】

The two people walking in front turned sideways and gave way to the road, and Liu Xianyu saw why the shooter would say that the road was blocked.

The white mucus hardened to form a white wall, which completely blocked the passage in front of him, stretched out his hand and gently tapped the white wall, and there was a sound like a stone, Liu Xianyu pulled out his sword and tentatively slashed twice on the wall, and found that although the wall was strong, it was not indestructible, but he looked up at the top of the tunnel only half a meter away above his head, Liu Xianyu said his worries:

[Although I can break this wall with force, but I don't know how strong the tunnel is, it may cause it to collapse, is there a way to open it safely with magic?] 】

[I can first test if this thing has a weakness to magic of a certain attribute, maybe it will melt if you burn it with fire.] 】

While saying this, the female mage took out a magic staff, asked Liu Xianyu and the others to retreat into the distance, and then whispered to the wall with her magic staff:

【Flame Ray!】 】

The staff in her hand began to shoot out a steady stream of flames like a flamethrower, and these flames quickly generated a large amount of heat in the narrow passage, and after about a minute, the female mage stopped casting her spell, her forehead was already covered with dense beads of sweat, and she stretched out her sleeve to wipe her forehead.

[No, it doesn't work at all.] 】

The white wall was still unscathed, and the burning of the flames did not have any effect at all, but Liu Xianyu and several people were sweating from the high temperature brought by the flames.

[Let's break it by force, every minute we drag on the boss, they may be in danger!] 】

The shooter said with some anxiety.

[That's all, I'll try to move as lightly as possible.] 】

Liu Xianyu stood up and held the long sword and began to seal the blade, and after more than ten seconds, he pulled out the long sword and penetrated the wall with a little force, just as he was about to continue to slide the long sword to open a door on the white wall, he suddenly found that the long sword in his hand was stuck in the wall, and the wind element condensed by the sealing blade had disappeared at some point.

[That's going to be like this...... Could it be that the material of this wall is so hard that it consumes all the wind elements in one go? 】

Thinking like this, Liu Xianyu tried to move the long sword in his hand vigorously without using the wind element to seal the blade, although the long sword was slow, it still began to slowly cut the wall, feeling the feeling of this long sword, Liu Xianyu thought for a while, and still withdrew the long sword.

[What's the matter, why don't you continue?] 】

The three jade onlookers next to them saw Liu Xianyu draw his long sword and asked.

[This wall seems to have the property of absorbing elements, no wonder the previous magic didn't work, it seems that you can only rely on brute force to break through, but I don't know how thick this wall is......]

Liu Xianyu glanced at the gap cut by the long sword, and the one-meter-long sword body was completely submerged in time and failed to penetrate the wall.

[Absorb the elements? In this case, it can only be broken by brute force! 】

As he spoke, the shooter pulled out a metal ball from his fanny pack behind him, made of unknown materials.

【Wait a minute! Anyway, it's a little bad to use it in this kind of terrain! 】

The moment the mage saw the metal ball, she shouted.

[This is also something that can't be helped, since that wall can absorb the elements, you can only rely on this thing, not to mention that you don't worry about the boss and them? 】

Ikatrius stared at the ball in the shooter's hand for a moment before speaking.

[Is this the legendary high-level magic power item - Shock Detonation Bomb?] 】

[That's right, this is the latest prop from Magic Energy Technology, a blasting prop that is completely different from the principle of elemental magic, as long as you use this, it will be easy to break through this wall!] After all, it's a super luxury item that costs one gold coin, and it's a prototype series that can only be bought in the West Country. 】

The shooter had a smug expression on his face when he introduced the bomb in his hand, and the mage on the other side also looked at the small metal ball with a sad face.

【…… Prototype or something, it sounds super dangerous, shouldn't there be a sudden explosion. 】

Liu Xianyu looked at the metal ball in the man's hand with some unease, the name of magic energy technology with unknown principles has long been accustomed to adventurous life, although he doesn't know the principle, but it does bring a lot of convenience to life, for example, the adventurer Rubik's cube hanging around his neck now is the work of magic energy technology, in Liu Xianyu's cognition, he has always regarded magic energy as electricity in another world, but today he suddenly found that there is such a thing as a magic energy bomb, which has somewhat refreshed his world view.
