Lu Changsheng needed more than just a few fragments of the Great Dao.

He required a large number of Great Dao fragments.

Relying on slow accumulation was definitely not feasible.

He had to think of another way.

Thus, Lu Changsheng roamed around the Secret City continuously.

About three days later, Lu Changsheng's eyes lit up.

He saw a task.

A Black-Clad Ancestor Realm was looking for an Array Master.

And it was a kind who was skilled at breaking arrays.

The reward was quite substantial.

Just by accepting the task, he would receive ten Great Dao fragments.

Moreover, upon completing the task, he could earn additional generous rewards.

But as for what kind of reward and how much, it had to be thoroughly discussed with the other party.

"A task with ten Great Dao fragments is certainly not simple."

"Moreover, what the other party needs is an Array Master; I am not an Array Master."

"However, although I'm not an Array Master, if it's just about breaking arrays, even an Array Master can't match me..."

Lu Changsheng was quite confident.

He was not an Array Master, but he walked the Red Dust Immortal Dao.

He had the decomposition ability of the Red Dust Immortal Dao.

He could analyze all things, rules, and so on.

What was merely analyzing an array?

Therefore, Lu Changsheng didn't hesitate any longer and walked straight over.

"Fellow Daoist, are you looking for an Array Master?"

Lu Changsheng asked.

"That's right. Are you an Array Master?"

The Black-Clad Figure asked.

He even sized up Lu Changsheng from head to toe.

Of course, both parties were disguised by the Thousand Illusion Mask.

Even by examining, nothing could be discerned.

Lu Changsheng neither confirmed nor denied and directly asked, "What kind of array do you need to break?"

The Black-Clad Figure calmly said, "No matter what array I need to break, if you truly want to take this task, you must first prove whether you are an Array Master."

"How to prove it?"

"It's simple. I have an array; if you can break through it, you will have proven yourself."

"Break the array? No problem, is there a time limit?"

"About a month, perhaps."

Lu Changsheng nodded in agreement to all the requirements.

This was considered the Black-Clad Figure's "assessment."

Only by passing the Black-Clad Figure's "assessment" and gaining his recognition of Lu Changsheng's ability could he agree to let Lu Changsheng take on the task.

"Alright, please follow me."

Thus, Lu Changsheng followed the Black-Clad Figure to a cave mansion in the Secret City.

In the Secret City, no one needed to worry about safety issues. 𝐟𝐫𝕖𝗲𝘄𝚎𝗯𝕟𝐨𝕧𝐞𝚕.𝕔𝕠𝐦

Anyone daring to act against the rules in the Secret City would invariably face death!

Even the Strongest Ancestor Realm was no exception.

Quickly, Lu Changsheng entered the Black-Clad Figure's cave mansion.

Inside the cave mansion, the Black-Clad Figure introduced himself, "Fellow Daoist, my surname is Lin."

"Fellow Lin, my surname is Lu."

The two merely revealed their surnames.

But whether those were their real surnames wasn't known.

Anyway, in the Secret City, it's impossible for anyone to use their real name; they always have to hide their identity.

"Fellow Lu, in my cave mansion, there's an array."

"However, this array can trap the Strongest Ancestor Realm; breaking it is not easy. Can you do it within the one-month time limit?"

The Black-Clad Figure directly revealed the truth and falsehoods about the array within the cave mansion.

Lu Changsheng's eyes narrowed slightly.

An array that can easily trap the Strongest Ancestor Realm?

An array like this is not trivial indeed.

It's even quite powerful.

And someone who can casually bring forth such a Great Array likely has strong capabilities, most probably being in the Strongest Ancestor Realm!

However, Lu Changsheng didn't care whether the other party was in the Strongest Ancestor Realm or not.

Right now, passing the other party's "assessment" was imperative.

"No problem."

Lu Changsheng nodded in agreement.

"Good, then Lin will activate the array."

Thus, the Black-Clad Figure directly activated the Great Array.

"Boom".

The Great Array descended.

This was a Great Array that could trap the Strongest Ancestor Realm; how could it be ordinary?

Just now, Lu Changsheng and the Black-Clad Figure were clearly sitting cross-legged face-to-face. Yet, when the Great Array descended, Lu Changsheng lost the sense of the Black-Clad Figure.

As if the Black-Clad Figure disappeared.

Lu Changsheng knew the Black-Clad Figure hadn't disappeared but that the array had blocked or distorted his perception.

Lu Changsheng stood up.

He now found himself in a dense forest.

The semblance of the cave mansion was gone.

"Illusion Array?"

"It doesn't quite seem like one, but can the Great Array change the world itself?"

Lu Changsheng extended his hand and then launched a palm strike at the forest below.

"Boom".

The forest was flattened by Lu Changsheng's palm strike.

But that was all.

In the blink of an eye, the forest returned to its original state.

However, this merely activated the Great Array without attacking Lu Changsheng.

After all, this was just an assessment of Lu Changsheng's "array-breaking" ability.

Lu Changsheng knew very well that relying on his own understanding of arrays would not be enough to break it.

He could only rely on analysis.

"I have only one month..."

Lu Changsheng knew time was of the essence.

Thus, he no longer hesitated, sat cross-legged, and directly employed the decomposition methods of the Red Dust Immortal Dao, focusing on analyzing this array.

Day by day passed.

As Lu Changsheng continued to analyze.

The mysteries of the Great Array gradually came under his control.

Analyzing a world, analyzing celestial spiritual objects, analyzing Immortal Treasures, etc., are indeed quite challenging.

However, analyzing an array capable of trapping the Strongest Ancestor Realm was not a difficult task for Lu Changsheng at all.

Currently, his progress in the Red Dust Immortal Dao had reached 60%.

With Lu Changsheng's decomposition ability, completely analyzing this array was a simple task.

Less than a month would be needed.
