Hearing that Leo was going out, Charlene couldn't help but worry: "It may be dangerous outside." ”

"There's no way around that, and when those things turn into corpses at night, we don't have to go out and clean them up. Now you have to figure out the terrain while you can see it clearly, otherwise it will be more troublesome when the time comes. Leo said very resolutely, and then opened the sturdy door of the magic tower, and knocked on it with a special rhythm a few times, "This is a code, I will be back soon, don't open the door to anyone else except me." ”

"Well, well, I understand, I understand. Charlene nodded again and again, but her expression became more and more nervous, and she didn't know what she thought.

Leaving the Magic Tower, Leo fully unleashed his mental power and walked towards the canyon. The mountains here are bare, devoid of any vegetation, and look desolate and dead.

And in the air, there was a disgusting smell that seemed to never dissipate, and you didn't need to think about it to know that it must have been emitted by the corpses of those spider demons and moths.

Leo stomped his feet on the soft earth, and sighed secretly, perhaps no one can say clearly, how many alien lives are buried under this land, this is the conquest and subjugation between planes.

In the eyes of human beings in the main material world, the lower intelligent beings in the lower planes are not at all beings that can communicate on an equal footing, they are only sources and obstacles of resources. Some of the more brutal organizations, in the process of conquering the plane, will even resort to outright genocide, leaving only some relatively tame ones to use as slaves.

No one can change this status quo, and no one wants to change it, it is the many secondary planes that provide extremely rich resources for the main material world, and also make the main material world more powerful.

In a few moments, Leo was already in the canyon, and he controlled all his emotions and focused completely on his surroundings.

I have to admit it. The topography of this canyon is very favorable for defense.

On both sides of the road, the towering and craggy mountain peaks reach into the sky, and I am afraid that it will be difficult for even the races with the ability to fly to climb over, let alone ordinary land races. In this way, the canyon, which is less than 100 meters wide, has become the only passage.

"No wonder the academy has set up a magic tower here, as long as the canyon is blocked, it will be difficult for those invaders to enter the forest. Leo thought silently, and suddenly realized that he had chosen the wrong word, because he seemed to be the real aggressor. And from a certain point of view, people are actually victims and heroic rebels.

At this time, there was a slight abnormality in the open spiritual power network. As soon as Leo's gaze shifted to the left-hand side, the ground more than twenty meters away suddenly began to stir. The next moment, a monster crawled out of the ground and let out a series of roars at Leo.

In Leo's eyes, it was indeed a monster. It is about 1.5 meters tall and looks like a human on the whole, but if you look closely, it is very different.

Its head is smaller than a human's. It has large, bubbling eyes on either side of its head, no nose, and a very sharp mouth like a giant straw. Its body is covered in yellowish fluff. In addition to the slender and long legs, there should be a pair of arms at the waist and on the chest. However, its arms are completely different from those of humans, and they resemble the joints of insects.

Even more peculiar is its long, bloated belly and the pair of charred gray wings on its back.

"Mothman ......" Leo immediately recognized the monster. Apparently it should have been burned and buried after being mistaken for death, but it turned out to be not dead or burned clean when it passed by. And he crawled out of the ground.

As its wings were no longer usable, the Mothman struggled to crawl towards Leo, with an unintelligible roar and bursts of powder spewing out of its mouthparts.

Leo stepped back cautiously, lest he be contaminated by the potentially poisonous powder.

He didn't attack immediately, but carefully observed the intelligent creature he saw for the first time in front of him. Yes, the Mothman is also a sapient being, as evidenced by the almost overflowing hatred in its eyes. Leo believes that if he gives the other party almost, the monster in front of him will definitely kill him without hesitation.

Perhaps it was too badly wounded, or perhaps it was already on the verge of death, and after crawling forward for a few meters, the mothman's movements slowly stopped, and finally remained motionless, apparently dead.

But Leo didn't dare to be careless, God knows if this thing would cheat to death, and there was no mercy in his heart at the moment. If he was dealing with a human, he might hesitate, but the appearance of the moth and the human was too different, so it was difficult for him to think of the moth as a creature like himself.

And since there was only one corpse, Leo also used some kind of delicate cleaning method, chanting a low incantation, and fierce flames burned on the corpse.

Burning is always the safest way.

"Quack!! "The corpse suddenly let out a stinging cry, and sure enough, it was cheating on death.

However, after withstanding the fierce flames, a few seconds passed, and the death of the fraud became real death. The flames continued until the corpse turned from charred to black ash, and the whole process lasted less than a minute.

A gust of wind blew, rolling up black ashes, and a life disappeared without a trace.

Leo couldn't tell how he felt, there were regrets, regrets, but there was also a hint of excitement.

He couldn't help but worry about his excitement.

Continuing on, there were no more living creatures or threats, and after more than ten minutes, the rumbling sound of water was heard, which sounded like a large river.

Leo quickened his pace with curiosity, and when he walked out of the canyon, there were endless mountains in front of him, seemingly forever boundless. And above the mountains, covered with thick black clouds.

"No wonder the college abandoned the North. ”

Leo suddenly realized. The sprawling mountains are so prohibitive that if they were to be conquered in an all-round way, they would probably result in a serious mismatch between the investment and the return, and they might even fall into the quagmire of guerrilla warfare from which they could not extricate themselves.

Thinking about it, Leo's gaze retracted and landed on the wide, raging river a few kilometers away.

Far away, Leo could still feel the intense vapor, and according to his eyesight, the width of the river was at least two kilometers, and the current was extremely fast. It's just that the color of the water is not the usual blue or green, but a disturbing black that looks like ink from a distance.

"Said on the mission. You are not allowed to cross the boundary river, but you are not allowed to approach, and at this time, there should be no danger. Leo guessed, picking up speed and moving on.

Water is the source of all life, and he is interested in this great river.

The distance of a few kilometers, at the speed of being increased by magic, is not too far, and in a short time, Leo is already standing by the river.

However, it was unexpected. The black water of the river does not have any peculiar smell, just like the most ordinary water source.

"And where did this black come from?" With such doubts, Leo tentatively picked up some water in his hand and brought it to his eyes for closer inspection.

This time he was even more surprised, because as soon as the water reached his hand, it was no longer black, but it became clear and transparent.

"What's going on?" said Leo activating the professor as he dipped his tongue into his mouth.

Soon, the professor gave the results of the analysis: water in a large river. It is exactly the same composition as the groundwater he drank before, and it is all good water with pure texture and just the right amount of minerals.

As for why it is black in the river, the professor did not find any clues. At least for now, it is not caused by any particular element in the water. This made Leo think that maybe there was something special in the riverbed that made the water in the entire river not reflect any light. As a result, it became like black ink.

Looking at the sky, the sun with a strange blood-red glow had already passed through the sky, and it might disappear from the sky in another hour or two. Leo pondered to hurry back. After a short rest, he stood up and prepared to return to the magic tower.

"Boom!" came the clear sound of water waves. Although his back was to the river, Leo could instantly tell that the sound was definitely not an ordinary sound of water.

"Another monster?"

He hurriedly turned back, and sure enough, a kilometer away from the river, a black thing was emerging from the river.

The thing only partially emerged, and on the back was a shell reflecting a metallic sheen, protruding in the center, a bit like a turtle shell, but it was not the same. And just the part that is exposed to the surface of the water has reached a width of five or six meters, so you can imagine how big the underwater part should be!

Thankfully, the thing didn't move, it just stayed in the distance, but it continued to float.

"What the hell is that?" Sensing that there was not much danger, Leo did not flee immediately, but remained vigilant and observed, but for some reason, he always felt that the thing seemed to be a little familiar.

However, as the thing continued to rise, Leo was not surprised, but laughed dumbly.

Because it wasn't a monster at all, but a magic tower lurking in the water, perhaps because it was almost dark, it rose to the surface to defend against monsters that might appear in the north.

It's no wonder that on the way over, I didn't find the other magic towers in the beard's mouth, it turned out to be hidden in the water.

Immediately after, several openings opened at the top of the magic tower, and a whole twelve thick metal pipes poked out, all of which were Galnon's magic cannons!

One cannon can cast three rounds of Garnon thunderstorm in one second, and twelve cannons are thirty-six rounds, what a terrifying firepower! A thousand-man team, I am afraid that it will be completely wiped out in a matter of minutes.

But Leo didn't understand, what kind of magic pool could power so many Garnon magic cannons, or why the river was pitch black because of this?

Leo originally wanted to go into the past to find out, but it was getting closer and closer to dark, and he was also worried that Charlene would not be safe alone in the magic tower, so he didn't dare to delay any longer.

..................

Returning to the Magic Tower smoothly, Charlene was indeed in a hurry, and when she saw Leo coming back, she hurriedly asked, "Why have you been there for so long, I thought something had happened to you." ”

"No, there was hardly any danger along the way. With some apologies, Leo told Charlene what had just happened, but did not mention the process of burning the mothman, so as not to cause unnecessary psychological pressure to the other party.

Hearing the magic tower appearing in the water, Charlene was also quite surprised, but she didn't delve into anything, but asked Leo to go to rest quickly.

Leo was tired after a busy day. He agreed with Charlene to wake him up as soon as it was dark, so he chose a random bed in the lounge on the first floor of the Magic Tower, and lay down in his clothes.

............

"Zilala!" a shrill electric explosion woke Leo from his sleep.

He suppressed his beating heart and quickly recovered from the discomfort of waking up.

Through the professor's time record, he quickly knew that he had slept for 4 hours, that is, it was already dark now, but this was completely beyond the agreement!

After a little thought, Leo realized that the explosion just now was probably Charlene controlling Garnon's magic cannon.

"Is this guy afraid that I will lose my grades?" he took a deep breath, hoping that he was not a villain, and then rushed straight out of the lounge, towards the third floor of the magic tower.

And through the crystal glass embedded in the middle of the magic tower, Leo has seen the situation outside.

There is also a moon in this world, but not blue, not silver, but purple. Under the purple glow of the moon, the whole world seemed to be shrouded in a light purple veil. It's just that this kind of scene doesn't give Leo any graceful feeling, but is very terrifying.

In particular, the entrance to the canyon, in vague conditions, is like a huge beast's mouth, ready to devour everything at any time, and some dark shadows can be faintly seen rushing out of it. Obviously, those must have escaped the defenses of the Boundary River.

At this time, the sound of "zilala" sounded again.

Leo immediately saw a blue ball of electricity spin and fly out. The diameter of the electric ball is less than half a meter, but it is surrounded by countless electric tentacles, and its speed is extremely fast, and it is at the entrance of the canyon in a blink of an eye.

Through the electric light, Leo had clearly seen that those black shadows were spider demons and mothmen, and the total number was not much, but there were no less than a dozen.

When they saw the electric ball, those spider demons and mothmen tried to dodge, but their speed was not comparable to that of the electric ball. What's even more terrifying is that the electric ball seems to have intelligence, and even if it is far away, the electric tentacles will still take the initiative to attack.

The electric ball swept by, and all the lives contaminated by the electric tentacles instantly stiffened, some of them were scorched black, and some of them burned violently.

In just a few seconds, the more than a dozen spider demons and mothmen were all wiped out.

This...... It's a massacre, a complete massacre!(To be continued.) )
