This is a difficult problem.

The original Qingtian Ancestor should have relied on the Sky City to earn avenue fragments bit by bit.

That method can indeed earn a certain amount of avenue fragments.

However, I'm afraid it will take a long time and must be accumulated slowly.

And even Ancestor Qingtian didn't accumulate many avenue fragments in the end.

Lu Changsheng needs more than a tiny fragment of the avenue.

He needs a lot of avenue fragments.

It will definitely not work if you accumulate it slowly.

Have to find another way.

Therefore, Lu Changsheng kept wandering around the secret city.

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

He saw a mission.

A black-clad ancestral realm is looking for a formation master.

And he is the kind of formation master who is good at breaking formations.

The reward is quite generous.

As long as you accept the mission, you will be given ten avenue fragments.

You can even get generous rewards by completing tasks.

But as for what kind of reward and how much reward, you have to seriously discuss it with the other party.

"The task of ten pieces of avenue fragments must not be simple."

"Moreover, what the other party needs is a formation master, and I am not a formation master."

"However, although I am not a formation master, if I just break the formation, a formation master cannot compare to me..."

Lu Changsheng was very confident.

He is not a master of formations, but he follows the mortal path.

He has the ability to analyze the world of mortals.

Can analyze everything, rules, etc.

What does it mean to analyze mere formations?

Therefore, Lu Changsheng no longer hesitated and walked straight over.

"Fellow Taoist, do you need to find a formation master?"

Lu Changsheng asked.

"That's right. Are you a formation master?"

The man in black asked.

He was even looking Lu Changsheng up and down.

Of course, both parties were disguised by the Thousand Fantasy Masks.

Even if you look at it, you can't see anything.

Lu Changsheng did not comment and answered directly: "What formation do you want to break?"

The man in black said calmly: "No matter what formation I want to break, if you really want to take on this task, you must first prove whether you are a master of the formation?"

"How to prove it?"

"This is simple. I have a set of formations. If you fellow Taoist can break the formation, that's it."

"Break the formation? Easy to say. Is there a time limit?"

"About a month."

Lu Changsheng nodded and agreed to the entire request.

This can also be regarded as an "assessment" for the men in black.

Only after passing the "assessment" of the man in black and allowing the man in black to recognize Lu Changsheng's ability will the other party agree to Lu Changsheng's taking on this task.

"Okay, fellow Taoist, please come with me."

So, Lu Changsheng followed the man in black and walked towards a cave in a secret city.

In the Secret City, no one needs to worry about safety.

Anyone who dares to take action in the Secret City will definitely die without exception!

Even the strongest ancestral realm is the same.

Soon, Lu Changsheng entered the cave of the man in black.

In the cave, the man in black introduced himself: "Fellow Taoist, my surname is Lin."

"Fellow Daoist Lin, my surname is Lu."

The two of them just shared a last name.

But it is not clear whether it is the real surname.

Anyway, in the Secret City, it is impossible for anyone to use their real name, and their identity must be hidden all the time.

"Friend Lu Dao, there is a magic circle in my cave."

"However, this magic circle can trap the strongest ancestral realm. It is not that easy to break. It is limited to one month to break. Do you have any problems, fellow Daoist Lu?"

The man in black directly revealed the reality of the magic circle in the cave.

Lu Changsheng narrowed his eyes slightly.

A magic circle that can easily trap the strongest ancestral realm?

This kind of array is not bad.

Even quite powerful.

And those who can easily pull out such a large formation are probably not weak in strength, and are probably in the strongest ancestral realm!

However, Lu Changsheng didn't care whether the other party was in the strongest ancestral realm.

Anyway, now you have to pass the other party's "assessment" first.

"no problem."

Lu Changsheng nodded in agreement.

"Okay, then Lin will activate the magic circle."

So, the man in black directly activated the formation.

"boom".

The great array is coming.

This is a large formation that can trap the strongest ancestral realm, how can it be taken lightly?

Lu Changsheng and the man in black were sitting cross-legged face to face just now, but when the formation came, Lu Changsheng lost his sense of the man in black.

It was as if the man in black had disappeared.

Lu Changsheng knew that the man in black did not disappear, but that he was blocked by the formation or his perception was distorted.

Lu Changsheng stood up.

He is now in a dense forest.

Where can I find anything that looks like a cave?

"Illusion array?"

"It doesn't seem like it, but can the formation change the world?"

Lu Changsheng stretched out his hand and then slapped it towards the forest below.

"Boom".

The forest was leveled to the ground by Lu Changsheng's palm.

But that's all.

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

However, this only activated the formation and did not attack Lu Changsheng.

After all, this is just a test of Lu Changsheng's ability to "break the formation".

Lu Changsheng knew very well that it was impossible to break through it with his own formation skills.

It can only rely on analysis.
