"Your task is to block this underground passage for me, and then follow the original road all the way north, and there is a wall nest about two hundred kilometers away, and that is your destination. Don't worry about finding a place, I'll let Thunderhawk pick you up. ”

This is the order that Liu Siyi gave to Bill the Minotaur in the valley.

Unless another underground passage is dug out, or there will be a fifth-order magic like the Dimensional Gate, otherwise you don't have to come up, Liu Siyi thought so.

In fact, he still has a question, that is, this underground passage is only ten kilometers long, and the straight-line distance between the underground space and the ground is only ten kilometers at most, as long as a reconnaissance technique can sense the surface world, so why is only one race of dwarves discovering this?

In fact, Liu Siyi is a bit of a bull. This underground space is diagonally downward, and only the underground entrance of this passage is so close to the ground, and the rest of the space is getting farther and farther away.

Cross mediated the war, the hell demons of the demon clan opened another battlefield, and the dark elves on the other side and the undead clan were at war with the elves on the ground, and this space naturally became the back garden of the dwarf clan and the gathering place of wanderers.

Imagine, where I have lived for countless years, every crack in the wall is very familiar, who will have nothing to do and carefully inspect it again? This is the psychology of people, and everyone is the same. The dwarves also discovered this passage that I don't know when and for what reason it appeared because of the regular cleaning of wild monsters, and as soon as the reconnaissance technique was released, the surface world was discovered, and there was a move to block the underground entrance.

Of course Liu Siyi didn't know these things, so he couldn't figure it out, he just hoped that the underground forces would find out later, and his biggest expectation now was Thunder Eagle, and he didn't know what kind of news he could bring back, as well as the task of the witch lord.

In his mind, it is easy to defeat a seventh-order class, as long as he is lucky, when he upgrades, he will upgrade his wisdom to a high level, and then summon a firebird, and use the firebird to attack himself as the auxiliary, how can the general seventh-order class fight? But now, he is only a second-order high-level strength, although his real strength is far more than that, but he is still powerless to deal with the seventh-order troops.

As for the arrest, it is even more difficult.

The size of the seventh-order troops is very huge, and although the Transfiguration can transform into a human form, will the other party honestly let you capture it? Whether it's killing or surrendering, it's countless times easier than capturing.

Let's wait until we have the strength to think about these questions, and now let's look at the boxy building in the south and see what it does.

"Whew~ It's better to be in the earthly world~" Liu Siyi exhaled lightly and sighed infinitely from the bottom of his heart.

At this time, he was riding on the back of the Thunderbird, and two large black birds were flying behind him with the blessing of lightning speed.

It's not that he doesn't want the two witches to ride together, it's that the two witches are resolutely opposed to it as a sign of respect.

Looking at the bright sunshine rising in the east, Liu Siyi's heart was full of hope.

There is no definite time in the underworld, and it is mainly divided by the brightening and extinguishing cycles of fluorescent algae. Fluorescent algae fluoresce for five days, which means that the underground world is in darkness for two days of the week, so it is difficult to grasp the exact time.

Liu Siyi didn't expect that this time he went down to reconnoitre, which didn't seem to take a long time, but it actually took more than a day. What's even more gratifying is that I didn't feel too tired, and it seems that the mage unit and the power obtained from the upgrade have given me great strength.

This time I have gained a lot from exploring the underground world, knowing the various forces in the underground world, the most important thing is that there is suddenly a sense of urgency in my heart, the underground forces may come up at any time, and I must not slack off.

……………………………………………………

A burst of golden light flashed, Liu Siyi picked up the gold coins and resources on the ground, shook his head, luck always runs out, this time, he opened the treasure chest and didn't get any treasures.

The next target was a golden treasure chest guarded by the elven sixth-order unicorn at the edge of the woods, this was the first golden treasure chest he had found in such a long time, and if he was lucky, he would be able to open a fourth-order treasure second only to a pseudo-artifact. And it was only a little detour, which did not affect the distance to check the stone house.

Thirteen, this number is not an auspicious number, I just don't know if it will affect you or me.

Looking at the thirteen unicorns playing by the woods, Liu Siyi felt a little nervous and a little excited. What was nervous was that he attacked a powerful sixth-order class for the first time, and he didn't know what the effect would be; I'm excited about the golden treasure chest, I don't know what treasures will be opened, whether it can compare to the three treasures that the witch lord took out. Especially if you are lucky enough, you can become a hero and gain advanced wisdom skills while advancing to the third rank.

As for becoming a hero or something, it doesn't matter, because mutation has some of the abilities of heroes, and advanced wisdom is a skill that he has been thinking about and looking forward to since he found out that he can't go back to the real world.

As a sixth-order class, the whole body is as white as snow, and the unicorn that can't find a single stray hair is very powerful, especially the white sharp horn on the head, needless to say the power of impact and piercing, and there is also a special attack blindness: as long as it is hit by a sharp horn, and it is a creature that sees with both eyes, it will be blind, only the undead, machines, and cave people are invalid.

Unicorns are powerful, and the evolved sixth-order high-level silver unicorns are even more powerful.

The same pure white, in addition to the stronger body strength and larger body size, the white sharp horns have also evolved into bright silver sharp horns. It also has the ability to go blind, but when facing a silver unicorn, even if it is not attacked, as long as it reaches a certain distance, it will still be blinded. Moreover, the silver unicorn is immune to the magic of blindness. In particular, the Silver Unicorn's bright silver unicorn has the ability to repel negative magic, and all magic power is reduced by 20% within the silver unicorn's magic radius, making it difficult to deal with.

Although he thought about it a lot, he still didn't stop in his hand, waving the magic scepter, and a thunderbolt exploded in an instant, landing in the unicorn group.

"Boom!" There was a bang, lightning overflowed, and electricity swept through the unicorn's body, and a hissing sound rang out.

The Hell War Horse of the Demon Clan's Hell Devil is a fifth-order class, that is, second only to the unicorn, but a fifth-order and a sixth-order, the difference is a big order, and the difference in ability between them can be clearly seen.

The Hell Horse can only withstand several lightning blasts, the first time it can't paralyze it, and the second time it's about the same. But the thunder light explosion hit the unicorn, the damage was not great, and the paralysis was only a matter of a moment, and it felt similar to the rune elders of the dwarf clan.

Ziz...... Zizi ...... "Looking at the dark purple ball of light in front of him, which gradually became more proficient, Liu Siyi carefully controlled the speed at which the spiritual power was input into the mana.

As we all know, the power of magic is not simply divided according to rank, of course, the higher the level, the more powerful the magic. There is also the amount of mana consumed when casting a spell also determines the power of this magic, for example, a great magician and a magic apprentice release a small fireball at the same time, you don't have to think about it to know that the small fireball of the great magician is more powerful, this is because the great magician injects more mana into the small fireball.

This is the first time that Liu Siyi has taken the initiative to control the power of magic, and it is to increase the power. He didn't want to make a mistake, in case the thunder light explosion exploded in front of him, he was not afraid of the magic damage of the lightning system, after all, there was a pseudo artifact of the lightning rune, but the thunderbird would definitely not be spared, wouldn't he fall down when the time came?

Focusing on the thunderbolts floating in front of you, the mana was continuously poured in, and as its color became darker and darker, it became more and more powerful, and it became more and more difficult to control.

Injected twice or three times the mana, you can clearly feel the mana in the thunder light explosion gradually abundant, and it still feels very relaxed, continue.

Four, five, that's when there's some pressure, but you can't just give up if there's pressure, or continue.

The color of the Thunderbolt began to darken.

Six times, seven times, Liu Siyi was engrossed, not daring to relax a little, he was already going all out.

Eight times, is this the limit? But I feel that I can still control it, and since I can control it, there is no reason to give up.

Liu Siyi already has sweat on his head, and he can't take care of these now.

Nine times, this is the real limit, he felt his body trembling, sweating like rain, if he continued in this state, even if he didn't inject magic power, he wouldn't be able to maintain much time.

Fight! Liu Siyi no longer hesitated, and immediately threw down this powerful version of the thunder light bomb. With a high concentration of mental power, he forgot about the danger, and injected magic power again while blasting out the thunderbolt bomb.
