Hearing there were more than thirty evil ghosts from the Fourth Realm, Xiao Mu was immediately interested.

Even though his strength had reached the Fifth Realm, the Fourth Realm evil ghosts could still contribute 10 to 15 Energy Points each.

Thirty of them would then contribute between three hundred and four hundred fifty Energy Points.

Adding two Fifth Realm evil ghosts, Xiao Mu could gain around four hundred to five hundred Energy Points.

Two hundred Energy Points were enough to mutate a lower-grade Exotic Technique Secret Manual, and four hundred meant two.

Not to mention, upon completing the task, there is an additional reward of three hundred Energy Fruits.

"Okay, this task is it, I'll take it."

Xiao Mu quickly made up his mind and decided to take on this task.

"Please hand over your Identity Badge so I can register it. After registration, others can't take on this task until you have completed it or failed, unless you share the task."

"Thanks!"

Xiao Mu took out his Identity Badge and handed it to the young mutant.

"You're welcome!"

The young mutant took Xiao Mu's Identity Badge, registered it, and then returned the Identity Badge to Xiao Mu. He also gave him several pieces of paper.

The pieces of paper were printed information that recorded the basic information of the evil ghosts in the Immeasurable Cave.

"If you need to undertake more tasks in the future, feel free to find me."

Xiao Mu said politely, took the Identity Badge, and left the Task Hall.

"The Immeasurable Cave is a bit far from here. Counting the round trip and the task time, it will probably take at least one week."

"To avoid Jiang Mu causing trouble, I need to prepare for a shift change in advance."

The next day, it was Xiao Mu's turn to guard the Ancient Palace again.

Xiao Mu arrived early at the Ancient Palace and waited, and soon after, Wang Kui, Miss Xuan Xin, and Zeng Guan arrived.

"Miss Xuan Xin, how do you do!"

Xiao Mu warmly greeted.

"Hi, is anything the matter?"

Xuan Xin's attitude remained cold.

"Ahem!"

Xiao Mu, a little out of sync with her style, coughed, and found a topic, "Miss Xuan Xin, did you enjoy the roasted chicken from the Pan family that I brought last time?"

"Delicious!"

As soon as food was mentioned, Xuan Xin's eyes lit up. She nodded vigorously, her throat moving intensely.

"How about I bring you one more when I go the next time?"

Xiao Mu asked with a smile.

"Thank you, but no need."

Xuan Xin's enthusiasm faded immediately, and she declined: "You only need to taste the same delicacy once in a lifetime, it's enough. I have the Return Light Technique, as long as I've tasted it once, I can always bring back any taste at any time."

The Return Light Technique? Food Return Light Technique?

There's such a secret art?

Xiao Mu was amused and gave Xuan Xin a strange look, and then said, "Miss Xuan Xin, there are a lot of delicacies in the world."

"I know."

Xuan Xin rolled her eyes, making a 'you're stating the obvious' expression.

"Have you ever eaten spicy strips?"

Xiao Mu tentatively asked.

"Spicy Strips?"

Xuan Xin was interested. Her eyes suddenly brightened, like two twinkling little stars.

It seems like she hasn't eaten them.

"Ahem, ahem, ahem!"

Xiao Mu coughed, "Tomorrow I plan to go out to complete a task, and when I come back, I can bring you a bag of spicy strips. Which flavor do you prefer?"

"Mr. Xiao, are there many flavors of spicy strips?"

Xuan Xin looked at Xiao Mu curiously, her throat was constantly moving, expressing anticipation.

"Of course."

Xiao Mu said, "If you're willing to be on duty for me for a few days, I will bring you a bag of spicy strips when I come back."

"At least three bags, with different flavors."

Xuan Xin, unsatisfied, held up three fingers.

"Deal!"

Xiao Mu chose to accept without hesitation.

How many flavors of Spicy Strips are there?

He can't really say. Each brand, each type could be considered a separate flavor.

The key point is they're extremely cheap to buy in bulk from the mountainside. A big box only costs ten thousand yuan.

Wang Kui and Zeng Guan shook their heads disapprovingly from the side.

"Xiao Mu, your actions are very devious," Wang Kui whispered, the reproof clear in his voice.

Trading three packets of Spicy Strips in exchange for Xuan Xin's help wasn't very fair.

Xuan Xin, a ghost who had attained Dao and was born in the mountains, didn't understand the worth of worldly objects. But he, who often travelled to the Mortal World, knew very well.

"Ahem, Brother Kui, do you want some too? When I return, I can bring you back three similar packs of Spicy Strips."

Xiao Mu turned to Wang Kui, a small smile on his face.

"No need. I have no interest in worldly food. And you should call me Wang Kui."

Wang Kui promptly refused and corrected Xiao Mu.

Zeng Guan quietly walked away, shaking his head. He wasn't typically talkative and didn't even have the interest to criticize Xiao Mu for his devious behavior.

The second day, Xiao Mu who smoothly transferred the duty to Xuan Xin, left the Song Relics.

He took a helicopter, then switched to a plane, flying towards the east of Da Liang City.

Two days later, he once again switched to a helicopter, and after half a day, arrived at the outskirts of some ruins.

This was evidently a true relic, giving off an aura of desolation and antiquity.

The atmosphere was filled with death qi, transforming into a faint black mist, it was like a city of wronged deaths.

There was no life in this city, it was wholly devoid of vitality— just a place standing eternal, as if no life had ever stepped foot in it.

A chill went down Xiao Mu's spine.

These were not ordinary ruins and their presence in the Mortal World was unexpected.

"Ahem!"

At the edge of the relic, a clay statue suddenly morphed, slowly turning into an old man with grizzled hair.

The old man coughed his way out, standing at the edge of the ruins, gazing at Xiao Mu.

"Another Mutated Being has accepted this task."

The old man's tone was filled with incredulity.

"I am the Human Mutant, Xiao Mu. Hello, Tu Bo."

Xiao Mu respectfully greeted the old man.

He knew who this old man was - the guardian of the Immeasurable Cave, and the task information had clearly stated this.

Important ruins like these were often guarded by mutated beings like Tu Bo.

Their task was simple.

On one hand, they had to guard the entrance of the Immeasurable Cave from being intruded upon by ordinary beings or weak mutants. On the other hand, they had to prevent the creatures within the cave from leaving and causing havoc in the Human World.

"Hello, Xiao Mu!"

Tu Bo responded, his words filled with sentiment, "Months have passed, but I didn't expect someone to take on the Immeasurable Cave task again."

"Xiao Mu, there's something you should know. This task isn't as simple as the information implies. Many mutants who accepted it ended up meeting their end at the hands of the evil ghosts within the Immeasurable Cave."

Tu Bo's expression became serious and he seemed worried, as if concerned for Xiao Mu's life.

"I've heard about it. However, I still chose to take this task."

A smile appeared on Xiao Mu's face.

He had meticulously read the task information and knew that several Fifth Realm mutants met a tragic end while undertaking the Immeasurable Cave task.

Among these mutants, there were those who were in the Mid Fifth Realm. Some even attempted to collaborate to complete the task, but ultimately failed.

"What's your realm? How many Secret Arts have you cultivated?"

Tu Bo, still unconvinced, asked about Xiao Mu's abilities, his gaze filled with pity.

He had seen this kind of confidence many times.

Every mutated being who accepted the Immeasurable Cave task was brimming with confidence, like Xiao Mu, but none had ever been able to complete the task or defeat the evil ghosts of the Immeasurable Cave. They all ended up dying at the hands of the ghosts.

"I'm Mid Fifth Realm and I've cultivated two Secret Arts in total."

Xiao Mu responded concisely.

Though he had only cultivated two Secret Arts, one integrated the power of Five Elements while the other blended the power of Yin-Yang. Additionally, he possessed a strange treasure—the Death-Expediting Clock—which was comparable to a Secret Art and was much more powerful than normal Secret Arts. Also, he owned a ghost servant who had cultivated the Scripture of God Transformation. Xiao Mu was utterly confident in his abilities.

"The Mid Fifth Realm. Your abilities are just sufficient to accept the Immeasurable Cave task. If you were any stronger, particularly if you were in the later stages, the evil ghosts would send out their elites to interfere with the task."

"However, you have only cultivated two Secret Arts, which seems a bit scarce. Xiao Mu, heed my advice and go back. The difficulty of the Immeasurable Cave task is beyond what you can imagine. There's no need to throw your life away for the reward."

Tu Bo advised, analyzed a bit, then shook his head. He clearly wasn't optimistic about Xiao Mu's chances.
