Liu Siyi has some abilities of heroes, but there is no guarantee that equipment such as the Night Pendant, which only works for heroes, can also be useful to him.

Now the problem comes out, if you don't go down, you will only know at night whether the night pendant can bless Liu Siyi with the attached night vision ability. Go down, don't have night vision and come up again?

Grass! Let's go down and see for yourself.

Liu Siyi felt helpless, because he had played some games such as dungeons, he was also very curious about the underground world, although there were some dangers, but he still decided to go down to reconnoiter and experience it himself.

Looking at the entrance of this underground passage, which is less than four meters high, there will definitely be some places that are more spacious and some places are more narrow for various reasons, and you can imagine how the dwarf's mount, a giant bear with a height of more than three meters, passed through.

The tunnel has small benefits, at least this is what Liu Siyi is willing to see.

The tunnel is small, at least it won't pass through the Dwarven Clan's seventh-order class, the Magma Dragon. Of course, if the magma dragon is available, then the dwarf clan can crush the current Liu Siyi with or without the magma dragon.

Handing over the unwanted treasures to the Thunderbird and instructing it to wait on the top of the mountain, Liu Siyi walked into the unknown darkness alone.

Near the entrance of the underground passage, there is still a faint bright light shining in, so you can see the surrounding environment clearly. As we went deeper, the light became dimmer and dimmer, until at last I couldn't see anything, and I couldn't see my fingers.

It's very dark, very dark, but in this absolute darkness, the black eyes on the night pendant on Liu Siyi's chest emitted a faint hazy black light, and in this black environment, you can't find it at all if you don't look closely.

Just when Liu Siyi thought that he really didn't have the ability to see night vision and was about to withdraw, suddenly, just after the next blink, he suddenly felt that he could see things. Everything can be seen very clearly, shape, size, distance, except for the color, which is a very strange feeling.

Entering the underground passage, I did not see the strange rocky scene, but a tunnel with obvious traces of repair. However, it is certain that this was not excavated by the dwarves, but a natural crevice formed by the movement between the earth's crusts, and then roughly excavated by the dwarves.

Not only was the floor of the underground passage leveled, but there were also traces of shovels on the walls, and there were traces of burned-out torches on the walls every few meters.

Obviously, before the dwarven heroes who were killed did not develop this wild virgin ~ female land, the usage rate of this underground passage was not very high.

The Eye of Perspective.

Although there was a tiger in front of him, as soon as he entered the tunnel, Liu Siyi immediately released this reconnaissance magic, and the spiritual power was radiated, which would consume a lot when penetrating the mud and rocks, but there was still a part of it moving in the direction of the tunnel, and this part of the spiritual power was still the same as before, all the way forward.

The number of tigers is still eight, but it can be clearly seen that each time you level up, you will become more powerful. Although it is still a third-order class, it is stronger than a third-order soldier no matter how you look at it.

Because the consumption of spiritual power through the soil and rocks is too great, Liu Siyi suddenly thought: I wonder if I can control these spiritual powers and let them act according to their own ideas?

Take advantage of this opportunity to give it a try.

It's always hard to do something the first time, and so is controlling mental power.

The previous release of magic and meditation cultivation were all done step by step according to the inheritance, according to the game terminology, this is the skill of knowing magic, which can be used but does not understand the principle, and it is impossible to innovate independently.

Liu Siyi didn't know that his idea, and the practical actions that followed, made him take an important step in the control of mental power.

Concentrate and control your mental power.

What is Mental Power? In the real world, the brick family will definitely say that spiritual power is a kind of energy that makes people's thinking run and think.

I can't be wrong, but in this amazing world, the nature of mental power and soul is similar to the relationship between strength and body. The stronger the body, the stronger the strength will naturally be, and in the same way, as the soul gradually becomes stronger, the spiritual power will also become stronger and stronger.

The strength of strength can be measured from carrying weights and carrying things, but there is no special instrument for measuring mental power, nor does it have a specific manifestation. Liu Siyi knew that this was mainly because there was no way to cultivate spiritual power in the real world, unlike strength, which could be increased through exercise.

With the meditation method of cultivating spiritual power, not only can you feel the elemental power, but while absorbing the elemental power, you are also using the spiritual power. And when the magic is unleashed...... Now, what Liu Siyi has to do is to rediscover the feeling of using spiritual power.

It's easy to say and easy to say, just bring that feeling into the air. But it's hard to say, and if you want to truly control your mental power, it's impossible to master it without a long period of training. It's unlikely that you'll want someone who has inexplicably strong mental power to control it quickly after only two levels.

Liu Siyi naturally didn't think about it so much, he was now standing at the entrance of the underground passage, his eyes closed, carefully perceiving the spiritual power that emanated. The speed at which these spiritual powers are emitted is very fast, and it is quickly clear in the brain that the range of perception is rapidly expanding.

Soon, the range of the Eye of Perspective no longer increases, but through perception, the range is reduced by more than half compared to on the ground. After all, this naturally occurring crack is not a straight line.

There is only one road in the underpass, just follow it.

Every time he walked a distance, Liu Siyi released his perspective eye to reconnoiter the situation in front of the passage.

For the control of mental power, it is not possible to do it for the time being, and Liu Siyi is not in a hurry, he uses the most stupid method, that is, practice makes perfect, which can be used as both reconnaissance and increased proficiency. Release more and be more proficient, and when the proficiency goes up, it will naturally come naturally.

The underground passage was much longer than the original reconnaissance, at least thirty kilometers down diagonally, and I don't know how long it took before it finally came to an end.

But unexpectedly, this end of the underground passage connecting the underground world is blocked by dirt. Moreover, this earthen wall is still very thick.

From the perspective eye, it can be clearly felt that behind this earthen wall, there is a huge underground world.

But? Why is it blocked? There are many theories about the dwarves having heroes enter the overworld from here, and then seal the passage with dirt, and also from the inside out.

Obviously, there are people who don't want this passage to be discovered by others, this person may be the dwarf hero, and Liu Siyi also hopes that it is him, because this shows that there are no worries.

But this possibility is too small, thinking about it, it should be that the dwarves are secretly infiltrating and developing into the surface world, but they don't want to be discovered by other racial forces.

In this way, it will be more troublesome, if the various forces in this place are complicated, Liu Siyi will feel a headache, he doesn't know how to get between the powerful and powerful.
