Then Xiao Mo and Xiao Han followed suit. Xiao Mo's Gravity Spell combined with Xiao Han's Dark Orb, a perfect synergy, truly seamless. Before long, they had eliminated the three figures in black who had been fiercely battling Mo Han, leaving behind several pools of greenish ichor on the ground, which made Mo Han flinch internally, cursing the mysterious shadow's ruthlessness.

However, Mo Han unintentionally discovered that the coordination between Xiao Mo and Xiao Han was absolutely flawless, perfectly compensating for each other's weaknesses. Xiao Mo’s Gravity Spell paired with Xiao Han’s long-range dark energy strike—if he had engaged alone just now, he might have been defeated. Even facing a Sword Saint, they might stand a chance. Thinking of this, Mo Han’s confidence in completing this mission grew considerably.

After clearing out these black-clad figures, Mo Han looked toward the sky and mocked lightly, "Your underlings are all dead. Aren't you coming out? Are there any tricks left? If not, I’m leaving."

Mo Han knew the shadow was definitely nearby, observing everything through magic; he could clearly sense that faint magical fluctuation in the air.

It was evidently caused by that mysterious shadow's sorcery.

Yet, he absolutely could not allow the shadow to discover that he was not only a Warrior but also a Mage. This was definitely a trump card against the adversary; how could Mo Han expose it so easily? Therefore, instead of addressing the source of the magical fluctuation, he spoke toward a different direction.

As expected, the moment Mo Han finished speaking, the familiar shadow materialized opposite him. "Boy. Not bad, you’re getting more and more interesting. It’s been a long time since anyone offered me such amusement. Heh heh. What kind of magical beast is that other one of yours? It doesn't seem weak; it even wields Time-Space Magic, a long-lost mountain valley technique. I am quite curious. Can you tell me?" Hearing this, Mo Han smiled faintly and replied, "Of course I can, but..."

He paused deliberately at this point.

Sure enough, upon hearing Mo Han's words, the shadow couldn't help but inquire, "But what? What trick are you trying to pull now?"

Mo Han grinned, his expression shifting back to that signature roguish smile. "If you call me 'Grandpa' three times, I might consider telling you. How about that?" Hearing Mo Han’s taunt, the shadow remained unfazed, merely stating coolly, "Even if you don't tell me, I will find out. The next time I seek you out, you won't get away so easily. I advise you to enjoy yourself now while you're still alive. I fear you might not have the chance to see me again alive."

With those words spoken, the shadow slowly began to fade.

Until it vanished completely.

At that moment, Daili approached and said, "Mo Han, why is it that every time we go somewhere, he knows our location and sets up an ambush beforehand? This person's strength is truly terrifying."

Mo Han nodded in agreement. "You're right. I suspect he uses some kind of magic that allows him to sense the fluctuations of the Battle Qi on our bodies, which is why he always knows our position so clearly. This is what he is most proud of, but it is also his greatest weakness."

Daili looked puzzled and asked, "Why? If it’s his proudest move, why is it also his greatest weakness?"

"Think about it. If someone could suppress the Battle Qi or magical fluctuations radiating from their body, wouldn't his technique become completely useless? As long as I can pinpoint where he is hiding, the problem is solved," Mo Han explained, a slight smile touching his lips.

Seeing this, Daili, knowing Mo Han well, realized he must have thought of a plan and couldn't help but ask curiously, "Have you figured something out?"

"Not entirely certain yet," Mo Han shook his head, a barely perceptible smile appearing on his face. "But I think this is an opportunity. This pervert has had so much fun messing with me these past few days; I certainly must find a chance to repay him properly, or I won't be true to myself."

After saying this, he smiled and led Daili and the others back to Toby's secret chamber.

Toby was slightly surprised to see Mo Han and the others return so early, and with a small girl in tow, but he said nothing, immediately taking the girl inside. Mo Han and the others circled the area once to ensure they weren't followed before feeling safe enough to return to the chamber.

Later, while chatting with the little girl, Mo Han learned that her name was Natasha, and she was also from Yima City. During the disaster two months prior, she and her parents had hidden in a room and survived. Afterward, the family hid in the cellar, waiting for a miracle to escape.

But a month ago, their emergency food supplies ran out. Her father reluctantly ventured out to search for provisions, but upon his return, he was discovered by the zombies. In order to protect her and her mother as they fled, her father was surrounded by the undead and never returned.

Subsequently, Natasha and her mother stayed in the city, constantly hiding and living in terror. Then, three days ago, Natasha and her mother were encircled by the zombies. Her mother bravely lured the undead away to cover Natasha’s escape and then disappeared without a trace, likely meeting a grim end. The poor girl was left hiding alone in a house.

However, after three days, she could bear the hunger no longer. So, under the cover of daylight, she secretly slipped out to search for food, which is exactly when Mo Han encountered her, leading to the scene they just witnessed.

Hearing Natasha's tragic tale, everyone in the room felt sympathy for the seven-year-old girl. Daili held her tightly, constantly comforting her. Under the care of the group, Natasha slept soundly for the first time, a long-absent smile gracing her small face.

The next morning, at Mo Han’s suggestion, Daili stayed in the secret chamber with Xiao Mo, Xiao Han, and Toby. Mo Han decided to venture out alone to investigate the area near the red wall, as he had found an Invisibility Ring inside the spatial ring given to him by Mo Xiuyi.

According to Mo Xiuyi's explanation, this ring was considered an ultimate item. Once worn, it allowed the wearer to become invisible for a period. No matter what method the investigator used, they absolutely could not detect the wearer’s fluctuations of magic or Battle Qi, unless the wearer chose to act. Thus, it was an excellent concealment tool.

However, the Invisibility Ring had a drawback: after one use, it required at least ten days before it could be used a second time, otherwise, it would have no effect at all. Furthermore, each use could not exceed half a day, making it, in a way, a double-edged sword.

Since Mo Han had inadvertently discovered yesterday that the mysterious shadow tracked his location via fluctuations in Battle Qi or magical elements, today he planned to use the Invisibility Ring to test if it was effective. This would also allow him to scout the situation inside the red wall. Even if he encountered danger, Mo Han was confident that with his own abilities, even if he couldn't win a fight, surely he could escape? Therefore, although Daili was very worried about Mo Han, after hearing his explanation of the Invisibility Ring and witnessing its effect firsthand, she couldn't argue much. She simply instructed Mo Han to be extremely careful before seeing him out of the chamber.

After leaving the secret chamber, Mo Han sprinted rapidly toward the location of the red wall. Aided by the Invisibility Ring, Mo Han had no reservations and used his full strength to rush toward his target. Before long, he arrived at the outskirts of the red wall.

Mo Han was currently hiding in a civilian house across from the red wall, observing the situation opposite him. Through his observation, Mo Han noticed a faint black mist constantly hovering around the perimeter of the red wall, especially obvious under the sunlight. It enveloped the entire courtyard, present everywhere; the moment one entered the courtyard, they were sure to touch that black mist.

Moreover, sounds occasionally emerged from within, but he couldn't ascertain what creatures were making them. Beyond that, he discovered nothing else.

However, Mo Han was certain: this must be the mysterious shadow’s hiding place, or a significant location. Although he didn't know what those black mists were, Mo Han was sure they were a magical barrier protecting the courtyard, and a potent one at that, perhaps even laced with deadly poison. Without a definitive certainty, Mo Han dared not risk crossing it lightly.

Just as Mo Han was preparing to leave in frustration, the door of a house next to the red wall suddenly burst open. Mo Han quickly focused his gaze. He saw a figure slowly emerge from the courtyard. At first, Mo Han thought he was mistaken, but upon closer inspection, he realized it truly was a person—a young man, appearing to be in his early twenties, dressed in what looked like noble attire, though it was filthy and disheveled from long disuse. He was quite handsome.

He leaped to
