The dean stood by the window, quietly looking at the night sky outside, and whispered, "This universe is far from as peaceful as you imagine. The survival of the Human Clan is actually a very difficult thing. It's not just threats from the other Eight Realms, more importantly, it's those unknown terrors."

"Unknown terrors?" Su Yang looked at the horizon outside, surprised, "Are those all unknown terrors?"

The dean nodded, "Compared to us, those indeed count as unknown terrors."

"What exactly are those?" Su Yang couldn't help but ask.

The dean glanced at Su Yang, calmly said, "Some powerful beings capable of traversing through this universe!"

Su Yang was startled to the core; beings capable of traversing the universe definitely possess significant power. At the very least, Su Yang was certain that not even reaching the Land Immortal Realm could enable traveling across the universe. To do so, one's power must be at least at the level of Beigong War God, with physical strength reaching a certain degree!

"Why do these powerful beings want to deal with the Nine Realms?" Su Yang couldn't resist asking, "They can already roam the universe, do they still need to set their sights on the Nine Realms?"

"Hehe..." The dean laughed softly, "Why do the other Eight Realms want to deal with the Human World?"

Su Yang froze for a moment, his brows wrinkled involuntarily, he said in a deep voice, "Do you mean that they are dealing with the Nine Realms for its resources?"

The dean shrugged, spoke softly, "That reason alone is sufficient."

Su Yang took a deep breath, he finally understood what's going on. As the saying goes, innocence stirs envy, possessing fine jewels attracts trouble. The Nine Realms possess abundant resources, and when those strong ones are soaring through space and discover such resources, they certainly won't let go. Therefore, they will definitely want to plunder the resources of the Nine Realms, which is the real crisis here!

Seeing Su Yang's expression, the dean gently continued, "Of course, those powerful beings in the universe cannot be clearly explained in just a few words. I'm only roughly explaining to you, the true situation, needless to say, not even the Nine Realms can clearly explain it now. You just need to know that in this universe, the Nine Realms are not the only place with living beings, nor the strongest place. To give a simple example, Feather Spirit Palace, Storm Valley, and Demon Abyss were once the three great deadly lands that crushed the Nine Realms. Any one of these three deadly places is not something the Nine Realms can contend with. But how did these three deadly places come about?"

Su Yang was dumbfounded, he had pondered these questions before. Now, piecing together what the dean had previously said, Su Yang suddenly realized, everything is exactly as the dean said. The things in this world are not as simple as they appear on the surface, huh!

Protect the Human World, or protect the Nine Realms?

Now, Su Yang finally understood what the dean meant by ideological differences!

"The difference between the Martial Champion and my ideologies lies also here." The dean smiled bitterly, said, "Maybe I am more soft-hearted, unable to bear the deaths and injuries of the Human Clan. All these years, I have clearly protected the Human Clan. No matter how the crisis outside unfolds, the Human Clan cannot become a sacrificial victim to protect other races. But the Martial Champion, views things more indifferently; in his view, the Nine Realms are originally a family, without distinction of races. His ideology is to gather the resources of the Nine Realms together, leaving behind a group of the strongest in survival battles, leaving hope for the Nine Realms, thus completely protecting it. As for which race might be completely wiped out, he does not care!"

Su Yang took a deep breath, for a moment, he didn't know how to articulate this situation.

Before knowing these situations, Su Yang merely thought the Martial Champion was a fame-seeking figure, hiding like a turtle. But now, Su Yang realized he misunderstood the Martial Champion!

"Since that's the case, why doesn't the Martial Champion come out to fight for his ideology?" Su Yang couldn't help but ask.

"He cannot come out." The dean spoke softly, "He must guard Jieyue Tower."

"Jieyue Tower?" Su Yang was stunned; he hadn't heard of this name.

"You've been to Jieyue Tower." The dean said.

"I have?" Su Yang widened his eyes; he didn't remember going to any tower.

"That's the platform he is guarding now." The dean said, "On that platform, there's a beam of light shining down. That beam of light is actually a tower formed by power, known as Jieyue Tower."

"That is Jieyue Tower?" Su Yang was full of disbelief; if the dean hadn't said it, he would have never guessed!

"Jieyue Tower is a tower that connects the moon and the ground; actually, it is also a passage, a passage able to directly reach the ground from the moon." The dean said, "The Human World is a space, an enclosed space, even those roamers in the universe cannot arbitrarily enter the Human World. The passage into the Human World is at the moon, through Jieyue Tower, they can enter the Human World."

"So, the Martial Champion guards Jieyue Tower?" Su Yang exclaimed, "He is to prevent those strong ones from entering the Human World?"

"It's just the last line of defense for the Human World; the real guardianship is upon the moon." The dean looked at the full moon outside, spoke softly, "Otherwise, where do you think the assassins went?"

"What!?" Su Yang was shocked further, looked at the moon outside, tremblingly said, "You... you're not saying the assassins went to the moon, right?"

"There lies the key to guarding the Human World!" The dean said, "Without the assassins guarding the moon, the battle would have long spread to Jieyue Tower. If the battle indeed reaches Jieyue Tower, then the Human World is truly not far from extinction!"

Su Yang gasped, the assassins had been continuously telling him that they were going to accomplish something very important. Su Yang did not know what they were going to do; now, Su Yang finally understood what the assassins were doing.

"By the way, the assassin said previously that on the Moon Dark Day, he... he would return..." Su Yang said, "This... this Moon Dark Day, does it have anything to do with the moon?"

The dean nodded, "On the Moon Dark Day, the beam of light on Jieyue Tower will dissipate. At that time, there would be no need to guard temporarily, so the assassin can return for a short period. However, he wouldn't be back for long, as the Moon Dark Day won't last for very long."

Su Yang felt a thrill of shock in his heart, quickly asked, "When will the Moon Dark Day occur? Why will there be a Moon Dark Day?"

"When exactly there will be a Moon Dark Day, it's not up to me, nor within our control!" The dean shrugged, "It depends on the assassin's pet."
