Chapter 30

"Your task is to block this underground passage, then follow the original road north for about two hundred kilometers. There is a wall nest there, which is your destination. Don't worry about finding the place; I will have the Thunder Eagle meet you there."

This was the order Liu Siyi gave to the minotaur Bill in the valley.

Unless another underground passage is excavated or a Dimensional Door spell of the fifth tier is used, you won't be able to come up, Liu Siyi thought.

Actually, he had another question: this underground passage is only about ten kilometers long, and the straight-line distance from the underground space to the surface is at most ten kilometers. Just one Reconnaissance spell would be enough to sense the surface world, so why did only the dwarf race discover this?

In fact, Liu Siyi was a bit obsessed. This underground space slopes downward, and only the underground entrance of this passage is so close to the surface. Everywhere else is increasingly farther away.

Kross mediated the war, the demon race's Hell Devils opened a new battlefield, and the dark elves and the undead race on the other side were fighting the surface elves. This area naturally became the dwarves' backyard and a gathering place for wanderers.

Imagine living in a place for countless years, where even a crack in the wall is very familiar. Who would bother to check it again? This is human nature, and everyone is the same. The dwarves only discovered this passage, which appeared for unknown reasons at some point, during regular cleaning of wild monsters. Once they used the Reconnaissance spell, they found the surface world and decided to block the underground entrance.

Liu Siyi, of course, didn't know these things, so he couldn't figure it out. He only hoped that the underground forces would discover it later. His greatest expectation now was the Thunder Eagle, wondering what news it would bring and what task the Witch Lord would give him.

In his mind, defeating a seventh-tier unit should be easy. As long as luck is on his side, upgrading and advancing the Wisdom Spell to a higher level, then summoning a Firebird, with the Firebird as the main attacker and himself as the support, how could a regular seventh-tier unit resist? But now, he was only at the advanced second tier. Although his true strength was far beyond that, dealing with a seventh-tier unit was still a challenge.

Capturing one would be even more difficult.

Seventh-tier units are all very large. Although the Transformation spell can turn them into human form, would they obediently let you capture them? Whether it's killing or recruiting, it's much easier than capturing.

These issues can be considered when he has the strength. For now, he should go and check out the square building to the south and see what it is for.

"Ah~ The surface world is still better~" Liu Siyi exhaled lightly, feeling an endless sense of relief from the bottom of his heart.

At this moment, he was riding on the back of a Thunderbird, with two large black birds flying alongside him, accelerated by the Thunder Speed spell.

It wasn't that he didn't want the two witches to ride with him, but they insisted on showing respect and firmly opposed it.

Looking at the bright sunlight rising in the east, Liu Siyi felt full of hope.

The underground world doesn't have a clear time, mainly divided by the cycle of bioluminescent algae. The algae emit light for five days, meaning that the underground world is in darkness for two days a week, making it difficult to grasp the exact time.

Liu Siyi didn't expect that this reconnaissance mission, which seemed short, actually took more than a day. More surprisingly, he didn't feel too tired, indicating that the power of the mage unit and the strength gained from leveling up were indeed powerful.

The exploration of the underground world was very fruitful, learning about the various forces in the underground world. Most importantly, he suddenly felt a sense of urgency, as the underground forces could come up at any time, and he couldn't afford to be complacent.

...

A flash of golden light, Liu Siyi picked up the gold coins and resources on the ground, shook his head, and thought that luck always runs out. This time, he didn't get any treasure from the treasure chest.

The next target was a gold treasure chest guarded by a sixth-tier unicorn in a forest. This was the first gold treasure chest he had found in a long time, and with good luck, it could yield a fourth-tier treasure, just below a pseudo-artifact. Moreover, it was only a slight detour and wouldn't affect his journey to check out the stone house.

Thirteen, this number is not a lucky one. I wonder if it will affect you or me.

Looking at the thirteen unicorns playing by the forest, Liu Siyi felt a bit nervous and excited. He was nervous because it was his first time attacking a powerful sixth-tier unit, unsure of the effect. He was excited because of the gold treasure chest, wondering what treasure it would yield and if it could match the three treasures the Witch Lord had.

As a sixth-tier unit, the unicorn, with its snow-white body and no impurities, is very powerful, especially the white horn on its head. The piercing power of the horn is self-evident, and it has a special attack: Blinding. Any creature with eyes that is hit by the horn will be blinded, except for the undead, machines, and cave dwellers.

The unicorn is powerful, and the evolved sixth-tier advanced silver unicorn is even more so.

The same pure white, but with greater physical strength and a larger body, the white horn has evolved into a bright silver horn. It still has the Blinding ability, but when facing a silver unicorn, even if not attacked, being within a certain distance will still cause blindness. Moreover, the silver unicorn is immune to the Blinding spell. The bright silver horn can dispel negative magic, and within its magic range, all magic power is reduced by 20%, making it very difficult to deal with.

Although he thought a lot, his hands didn't stop. Wielding the magic staff, a Thunderball instantly formed and landed among the unicorns.

"Boom!" A loud explosion, lightning scattered, and the unicorns let out a chorus of screams as the current passed through their bodies.

The demon race's Hell Devil's Hell Horse is a fifth-tier unit, just below the unicorn. However, the difference between a fifth-tier and a sixth-tier unit is significant, clearly showing the gap in their abilities.

The Hell Horse can only withstand a few Thunderballs. The first one doesn't paralyze it, and the second one is almost the same. But when the Thunderball hits the unicorn, the damage is minimal, and the paralysis lasts only a moment, similar to the effect on the dwarf race's Rune Elder.

"Zzz... Zzz..." Looking at the deep purple ball in front of him, Liu Siyi carefully controlled the speed of his mental energy input.

It is well known that the power of magic is not simply divided by level. Of course, the higher the level, the greater the power. The amount of magic power consumed during casting also determines the power of the spell. For example, a Grand Mage and a Magic Apprentice casting a small fireball, the Grand Mage's fireball is obviously more powerful because more magic power is injected into it.

This was the first time Liu Siyi actively controlled the power of a spell, and he wanted to increase its power. He didn't want to make a mistake; if the Thunderball exploded in front of him, he wouldn't be afraid of the lightning damage, thanks to the Lightning Rune pseudo-artifact, but the Thunderbird would definitely be affected, and he would fall.

Focusing all his attention on the floating Thunderball, he continuously injected magic power. As the color deepened, the power increased, and it became harder to control.

Injecting two or three times the magic power, he could clearly feel the magic power in the Thunderball becoming more abundant, and it still felt easy, so he continued.

Four times, five times, the pressure started to build, but he couldn't give up just because of the pressure, so he continued.

The color of the Thunderball began to deepen.

Six times, seven times, Liu Siyi was fully focused, not daring to relax, already giving it his all.

Eight times, was this the limit? But he still felt he could control it, so there was no reason to give up.

Sweat appeared on Liu Siyi's forehead, but he couldn't afford to care about it now.

Nine times, this was the true limit. He felt his body trembling, sweat pouring down, and if he continued, he wouldn't be able to maintain it for long, even without injecting more magic power.

Go for it! Liu Siyi didn't hesitate, immediately throwing down the enhanced Thunderball. His highly concentrated mental energy made him forget the danger, and as he launched the Thunderball, he injected more magic power.
