Seeing Ando’s expression didn’t seem like a lie, Mo Han couldn't help but ask doubtfully, “Then why do you have that dark aura on you? Don’t tell me you’re a Dark Mage?” Hearing Mo Han’s words, Ando hurriedly spoke, “The dark aura you mention should be related to the cultivation method I’m practicing now. A mysterious person from the Underworld previously offered to teach me powerful Underworld martial arts, and he promised that when the Underworld rules the continent, he would make me a king of a nation. That’s why I agreed to his request, but I am absolutely not one of the Underworld people; I hope you can believe me.”

Mo Han listened, pondered for a moment, and slowly said, “Fine, even if what you say is true, as far as I know, all the people the Underworld sent out before seem to be dead already, right? Even those who didn’t die were imprisoned by the Church of Light. So how did you get in touch with that mysterious Underworld individual? What does he look like? You had better not lie. I know much more than you imagine, so you should understand what I mean.”

Hearing this, Ando nodded his head vigorously like a rattle drum and said, “My Lord, rest assured, I will tell you everything I know. It’s just that I have never actually met the person from the Underworld, so I truly don’t know what he looks like.

I know what I’m saying is hard to believe, but you must believe me; everything I say is the truth.

I truly dare not conceal the slightest bit.”

Mo Han nodded upon hearing this, signaling Ando to continue.

Seeing this, Ando quickly began to recount in detail how he got to know this mysterious Underworld person.

It turned out that more than a year ago, when Ando was exploring an ancient ruin with several mercenary groups, besides discovering that Demon-Repelling Stone, Ando unexpectedly picked up a strangely shaped black stone. However, Ando couldn't find any secret on it at all. It was just that this Demon-Repelling Stone and this strangely shaped stone were placed in the same room at that time.

So Ando kept a close watch and kept the black stone with him instead of discarding it on the spot.

But a few days later, Ando suddenly felt a strange vibration from the black stone in his arms. Curious, he took it out to observe, and then he saw the black stone suddenly emit a strange light. Immediately afterward, a mysterious Underworld voice appeared in Ando's ears.

The other party clearly told Ando that he was from the Underworld and that the Underworld would invade the Dragon Soaring Continent in two years.

And that they would rule over all humanity, and with humanity's current strength, they were no match for the Underworld.

The other party said that as long as Ando agreed to act as a sentry for the Underworld's invasion and report the human situation to him at any time, he could impart the highest martial arts of the Underworld to Ando. Furthermore, when the Underworld successfully ruled the continent in the future, Ando would be made a king of one of the nations.

At that time, Ando’s strength had long been stuck at the level of an Advanced Sword Master, unable to advance a single step further.

Upon hearing the other party’s conditions, he couldn’t help but be secretly moved, so he agreed to the request in one go.

He became the eyes of the Underworld on the continent, constantly reporting the latest human developments to that mysterious Underworld person. In return, the other party fulfilled his promise and taught Ando the Underworld's martial arts. After learning the techniques imparted by the other party, Ando indeed quickly broke through his original realm and reached the realm of a Great Sword Master.

Hearing Ando’s explanation, Mo Han’s heart couldn’t help but grow heavy.

He hadn't expected the Underworld to be so pervasive, able to monitor human movements even from the Underworld. Moreover, Mo Han had a nagging feeling that Ando was certainly not the only mole the Underworld had among humans. There must be quite a few others who had been lured by the Underworld’s highly tempting conditions and had become the eyes and ears of the Underworld on the continent. If this was the case, the hope for human victory in this war against the Underworld would likely become even more remote.

No, he absolutely had to find a way to eliminate these Underworld sentries. Otherwise, these sentries might become ticking time bombs; no one knew when they might detonate and cause how much damage.

The members of the Sky Shadow Mercenary Group, upon hearing that Ando was willing to betray his own countrymen for personal gain and become a running dog for the Underworld, all cast looks of contempt towards Ando. This included even his original accomplices, Mal and Habaili, who showed him the same expression. This was because they all understood that if the continent were truly ruled by the Underworld, there would likely be no hope for humanity to ever rise again. Although they weren't exactly good people, they knew how to choose in this critical moment of national survival. For Ando to become a lackey of the Underworld was truly beyond their expectations.

After listening to Ando’s explanation, Mo Han spoke coldly, “Where is that mysterious stone now?” Hearing this, Ando pointed directly at his chest and managed to say, “It’s right here in my arms, My Lord. If you don't believe me, you can take out the black stone right now to verify.”

Mo Han swiftly reached out and pulled a strangely shaped black stone from Ando’s embrace. This stone looked no different from an ordinary rock, except that it felt quite cold to the touch. Moreover, Mo Han could feel a significant dark aura emanating from it. Seeing this, Mo Han concluded that Ando was telling the truth and that this stone was likely not as simple as it appeared.

Thinking of this, Mo Han asked Ando, “How do you usually contact the other party?” Ando shook his head and replied, “The other party always contacts me. At that time, this stone will react naturally. I can’t contact him at all. He contacts me every period, but the contact time is never fixed—sometimes it’s a few days, sometimes a month. I can’t specify the exact time.”

Hearing Ando’s explanation, Mo Han felt a slight disappointment. If this was the case, he still didn't know how long he would have to wait before encountering this mysterious Underworld person. Mo Han was unwilling to give up, so he channeled a trace of his mental energy.

The black stone slowly permeated, wanting to see if there was anything different about it.

However, just as Mo Han’s mental energy penetrated the stone’s interior, he felt a powerful dark aura surge violently towards his body along the black stone. The intensity of this dark aura even surpassed that of the Underworld General Mo Han had encountered previously, reaching a terrifying level. With Mo Han’s current cultivation, he was unable to resist the invasion of this dark aura. The dark aura instantly took control of Mo Han’s entire body, nearly causing him to fall into a coma.

Around him, Daili and the others saw a dense black mist suddenly surge out of the black stone in Mo Han’s hand, instantly enveloping his entire body. Daili and Murong Feixue were greatly shocked when they saw this and rushed forward, but they were stopped by Bai Ling, who had remained silent until then.

Only then did Bai Ling speak in a rare, grave tone, slowly saying, “Don't go near it! This black mist carries an extremely strong Death Force. If you approach it, you will likely be corroded by the Death Force within. Not only will you be unable to save Mo Han, but you will also sacrifice your own lives.”

Meanwhile, Mo Han, situated at the center of the black mist, was in extreme danger. Mo Han felt that the dark energy seemed to have completely controlled his body, rendering him unable to move. He could only watch helplessly as the black mist, laden with the aura of death, rushed over and quickly penetrated his body, entering Mo Han’s interior.

As the dark auras surged in, Mo Han felt his vitality rapidly draining under the erosion of the Death Force, yet he was completely helpless, forced to watch this happen. For the first time, Mo Han felt a sense of fear in his heart. What kind of entity could possess such an intense dark aura? Even he, who was a Saint Mage, could not resist the erosion of this dark energy in the slightest.

As his vitality rapidly depleted, Mo Han felt dizzy and on the verge of fainting. But Mo Han resisted, knowing he absolutely could not pass out. If he fainted now, he might never wake up again. Thinking of this, Mo Han relied solely on his powerful willpower to fight the dizziness, keeping himself from falling into a complete slumber. However, even Mo Han himself didn't know how long he could hold on.

Because Mo Han could clearly sense that after encountering his resistance, the dark aura’s energy seemed to become even stronger, surging madly towards his head. Mo Han’s initial resistance almost completely collapsed, and he fell into a semi-comatose state, retaining only a sliver of willpower to prevent complete unconsciousness.

Just then, in his muddled state, Mo Han seemed to hear an extremely seductive voice echoing in his mind: “Stop resisting, child, you’ve been through enough hardship. As long as you give up resisting, you will soon become my most loyal servant. Then you will possess even greater power than you have now, and you will possess endless vitality, becoming an immortal existence just like me. Now, these dreams of glory are only one step away from you. Just give up resisting, and you will quickly attain this godlike power.”

Hearing this seductive voice, Mo Han was nearly ready to give up resisting. But at the critical moment, the Light Jade Pendant kept in Mo Han’s embrace emitted a wisp of light energy, which instantly surged into the top of Mo Han’s head, immediately restoring his consciousness, which was about to fall into a coma.

Upon sensing this change, the mysterious voice let out a surprised "Eh," and remarked, “So you have a Light Jade Pendant on you? Are you from the Church of Light? No wonder you could sense the dark power on this Ando. However, even with the Light Jade Pendant, you absolutely cannot resist my dark erosion. The Light Jade Pendant will only buy you a little more time to linger on. In the end, you will still be unable to escape the fate of submitting to me. Being my servant is your honor, do you understand? Hahaha…”

Over there, Daili and Murong Feixue became even more anxious after hearing Bai Ling’s explanation. They knew from Mo Han that Bai Ling’s true magical cultivation level was even higher than Mo Han’s. Now that Bai Ling said this, she certainly wouldn't be deceiving them. But if that was the case, wasn't Mo Han in even greater danger? Thinking of this, Murong Feixue hurriedly pleaded with Bai Ling, “Miss Bai Ling, please save Brother Mo Han! Right now, you are the only one here who can save him.”

Daili also looked at Bai Ling with hopeful eyes.

Seeing this, Bai Ling nodded to Daili and the others and said, “You don’t need to worry like this. I will naturally save him; he still owes me a lot of debts. If I let him die like this, wouldn't I suffer a huge loss? However, this dark aura is the most powerful energy among all the dark auras I have ever seen. I don't have complete confidence; I can only do my best. You all stand back first.”

Having said this, Bai Ling began to chant softly: “Oh, winds floating in the sky, oh, fires wandering on the earth, in my most perilous moment, I request your assistance! Lend me your strength to vanquish the evil, to tear apart the shroud of darkness! By the will of the Dragons, unleash the strongest combination! High-Tier Demon-Subduing Rite Dragon Curse—Fervent Flame Gale Dance!” As Bai Ling’s melodious spell resonated, countless wind and fire energies rapidly gathered before her under her guidance, creating an astonishing momentum. The fire elements directly formed the likeness of a giant fire dragon, and the wind spirits revolved around the fire dragon, amplifying the majesty of its flames.
