The content of the oath is divided into two parts, one is that the onmyoji himself cannot study and apply it, and the other is to prevent other secular people from manipulating it. Pen? Interesting? Pavilion wWw. ｂiquge。 info In other words, if you just look for it and save it, you shouldn't break this oath, maybe Haranosuke also wants to know the ultimate goal of the task client and wait and see, right?

Since he doesn't pursue it anymore, I'm happy to be quiet, but I can't report these secrets to Tsunade.

Early the next morning, I finally said goodbye and officially embarked on the mission journey.

The first place to go is "inside the pent-up mountains", so I have to find an active volcano first.

In addition, it is an active volcano where molten matter has accumulated in a magma sac and may erupt at any time.

There are generally three bases for judging whether there is an active magmatic system beneath a volcano. First, there is hydrothermal activity or fumarole in the volcanic area; second, there are frequent microseismic activities in the central area of the volcano; Third, there are observable surface deformations in the volcanic area.

Although Japan is located in a volcanic zone, it is not impossible to say that volcanoes erupt at any time. However, it is very easy to find an active volcano with hydrothermal activity or fumarole, in fact, there is such an active volcano in the Land of Smoke in the site of one of the graduation exercises I participated in before, and Kako and Soma should be quite familiar with it, and of course, there is Jingle Bell......

Speaking of which, let's revisit the old place~

After coming down from the direction of Kotoku's house, and arriving at the boundary of the land of smoke, the route I took was exactly the one I had delineated, so when it was dark and I needed to sleep in the open, I naturally took Sanxiao to the mud and stone cave.

"Wow! Where else is there such a nice natural cave here!? As soon as she jumped down and looked at the surrounding environment slightly, Kako couldn't help but cry out. After nearly two years with me, she is much more cheerful than before.

"No, it's not like a natural cave~ Even if it's natural, it should have been artificially repaired." After a closer look, Ding Dong said with a frown.

Soma didn't participate in the discussion of the two women, but immediately started to clean up the ground, and soon sorted out a flat, clean ground enough for the four of them to rest - walking with the three ladies, he has always been very conscious of taking on most of the manual labor.

I had already paid attention to what Clank Bell said, but the last time I came, I was in a hurry and didn't look closely, but I just roughly judged that there was no danger and left, and now I have a chance to observe again.

At first glance, there is nothing unusual about this place, except that it is a natural cave with a somewhat regular shape, but after looking around, I found that the soil on the cave wall near the central volcano is obviously a little loose. Although the color and flatness of this part of the soil are no different from those around them due to the age, the force that is fed back by the subordinates is very different when they are pressed on time.

With this discovery, I couldn't help frowning, it seems that there have been other visitors here before us~

beckoned the three children to work together, and quickly cleaned up this piece of cave wall, revealing a hole more than one person high.

"Huh~" I exhaled slowly, and an indescribable emotion came to my heart, but I was no longer in a hurry to do it, let them all disperse and rest, and wait for tomorrow to continue exploring.

Although it is a discovery, it is difficult to say whether it has anything to do with the task, but in the face of an unknown thing, I always have great curiosity and want to find out, so this tone is both admiration and helplessness, and there is also a faint ease of being able to devote myself to one thing and forget about the troubles for a while.

In the blink of an eye, it was dawn again, after everyone washed up, after finishing breakfast, they all gathered in front of the cave entrance, out of caution, I stayed outside as a doppelganger, and then took the three children into the dark passage.

Compared to the cave outside, this passage seems to be completed with the help of some kind of earth escape ninjutsu, which is a little rough and narrow, but it is still possible for two people to walk side by side. Although he was careful along the way, nothing happened, but after a long distance, he found a boulder blocking his way.

Obviously, this is not some elaborate mechanism, but it is just an obstacle that has been carried out of nowhere, or perhaps created by ninjutsu. At this point, I began to miss Kakashi's Rachel Electric Explosion, which was a great way to destroy the structure of the monolith, but Kakashi was not there, so I had to do it myself......

A reinforced icicle shatters the roadblock, sees nothing unusual in the road ahead, and moves on.

After a long distance, there was another boulder......

Although the chakra required for the ice pick technique is not too much, it can't withstand such consumption, right? If it's like this all the way...... I began to pause and think.

However, just as I stopped moving, someone had already started moving.

Soma's wind and rain have been quietly unfolded, I hurriedly dragged Xiangzi and Ding Dong backwards, so as not to harm the pond fish, at this time I can already feel the air surge around me, and after a while, I heard Soma shouting: "Break the sky turbine!" The air in the passage suddenly sizzled away from us as if it had been drained, and for a moment there was a slight suffocation, and from the front there was also the sound of gold and stone cracking, and I was still a little worried about Soma's situation, so I hurriedly ran back.

Soma stood in place and didn't move, just focused on watching his sword work.

The boulder is still standing in place, but if you look closely, you will find that it is covered with countless fine cracks - although it is only a knife, but the energy contained in this knife is a combination of countless previous knives - each crack represents an arc in the wind and rain in the eight directions, however, these energies are not dispersed, but are integrated with Soma as a relay station to form a whole, so there is such a power.

However, Soma frowned there as if he was very dissatisfied.

As soon as my enhanced icicle technique came out, the stone began to fall as if it had been weathered, and soon became a pile of ice ballast, but after the empty turbine was broken, the boulder was still standing still, which couldn't help but make him a little frustrated.

But I don't think so, a reinforced icicle will cost about a quarter of my chakra, and although I can open the first door now, I don't want to make myself too embarrassed if I don't meet an enemy. Looking at the appearance of Soma, it doesn't seem too reluctant to use the empty turbo a few more times, as a middle ninja with such strength, I think it's very reasonable!

Standing in front of him, I pulled out a stone chip from the boulder, because it was too narrow, the sharp edge was no less than the real blade, and as I moved, the boulder began to peel off piece by piece, and soon a mountain of knives erected by a pile of stone flakes was piled up on the ground.

……

It's not easy to pass this posture......

The three children have all gathered, and they all pouted helplessly at this time. I took out the knight's hammer from the package, and when I went up, it was a mess, and Soma also put the knife into the sheath and smashed it with it.

The passage was narrow, and Xiangzi and Jingle did not have the tools to take advantage of it, so they stayed behind and did not move, and soon we smashed all the stone chips and laid them on the ground, as long as we paid a little attention, we should not be hurt, and the group continued to walk forward through here.

Then, as I expected, a third boulder appeared, which was also given to Soma......

After walking for so long, everyone could feel that the passage was moving lower and lower, and as we continued to move deeper into the ground, and as we got closer to the central volcano, the temperature in the passage became higher and higher, and the faint smell of sulfur appeared in the air after breaking the third boulder.

Ah!

It occurred to me that it made sense for anyone who had come before, whoever it was, and whatever the purpose, to set up these three boulders behind them, because if this passage led all the way to the heart of the central volcano...... Then, even if we are not greeted by hot magma, the poisonous volcanic gas alone is no longer something we can bear!

Belch...... Am I being a little reckless?

If the volcano in the Land of Smoke was on the verge of eruption, the pressure inside the magma sac might not be enough to break through the limestone piled up at the top of the mountain, but once we broke all the boulders in this passage and made a small opening in the magma sac from the side down, giving the pressure a way to vent, the consequences would ......

Thinking of this, I couldn't help but break out in a cold sweat. Prudent, deliberate! I admonished myself in my heart.

Judging from the concentration of the sulfur smell, we are still far from the magma sac, to say the least, there is still a reliable obstacle between us and the magma sac, so we immediately ordered the three small retreats and returned to the surface from the original way.

Moreover, after coming up, he hurried to the nearest settlement, found a local old man, asked him about the eruption of the volcano, and asked him to judge whether the central volcano was about to erupt in the near future, and whether the underground lava activity was violent.

Fortunately, the old man's answer made me very relieved, according to him, at least for 20 years, the central volcano should not erupt, but this can also be understood that after 20 years, the central volcano may erupt......

Twenty years is a small amount of time for the lifespan of a volcano, which means that the central volcano is already on the verge of eruption! Any little thing has the potential to become the fuse for its eruption!

……

Thinking about the stakes of this, I was completely confused.

The country of grass collapsed the bridge between heaven and earth, and I hardly felt the slightest guilt; The country of Kawanobu resisted and destroyed almost half of the forest, and I don't care; I didn't hesitate to carry out the Craftsman's Craftsman's action against the Hammer's feet, but now it's in my own country! If the central volcano really erupts early, then the few villages near the foot of this mountain that have not been prepared and precautioned in the slightest will be completely destroyed! Even if I could have given them the right warning to move in time, the impact of the eruption on the environment would be immeasurable!

Do I want to continue ...... my mission?
