My disciple's cultivation returns ten thousand times, so I have to be invincible.

Zhong Qing looked at the three secret realm keys in his hand and fell into deep thought.

Feng Aotian, who was standing by, was a little confused, but he said excitedly, "Master, now that you have all three keys in your hands, this is like adding wings to a tiger."

If he had previously thought that the probability of his master obtaining the treasure was 80%.

Now, it's completely certain.

Zhong Qing shook his head.

"It's still too early to be happy about this key, as we're still unsure whether it's real or fake."

As soon as these words were spoken, Feng Aotian's face froze.

Then he frowned and said, "Could it be that he dared to sell fake goods to Master?"

"Hard to say!"

"However, we can verify it first."

As he finished speaking, Zhong Qing looked towards the Fallen Immortal Secret Realm under the clouds.

At his call, the master and disciple moved and disappeared from the spot.

Soon, they arrived in the clouds above the bronze gate.

"Rumble..."

As soon as Wu approached the ancient bronze door, he heard a thunderous roar all around.

Surrounding the ancient bronze gate is a whirlpool that stretches for tens of thousands of miles.

In the vortex, there was a faint fairy light dancing and crystal talisman light flashing.

That is an ancient formation!

If the entire secret realm has an ancient bronze gate as its entrance, then this formation is the wall of the secret realm.

The two of them were standing in front of the ancient bronze gate, like ants looking at a mountain.

Majestic, tall, vast and ancient.

Feng Aotian took a closer look at the ancient formation hidden in the vortex.

His expression changed slightly.

"I can feel that there is a terrifying power hidden in this formation."

"Once triggered, it will cause this great formation to become restless, and it will probably turn into boundless murderous intent, annihilating everything around it."

When it comes to formations, Feng Aotian believes that he has reached the pinnacle of perfection.

But this ancient formation still made him feel terrified.

He couldn't see through it, but he instinctively felt that this formation was very dangerous.

Zhong Qing was also looking at this formation.

But what surprised him was...

This formation gave him a sense of déjà vu.

After a little thought, he understood where this sense of familiarity came from.

Recalling the time when he crossed the entire Chaos Demon Sea and passed through the Tianyuan.

There, I met the Lord of the Abyss!

The opponent used the ten ancient killing formations to deal with him.

This formation seems to be similar to the killing formation, and they even have the same origin.

This surprised him a little.

The origin of the Lord of the Abyss seemed to be more extraordinary than he had imagined.

At the same time, he couldn't help but sigh at the domineering immunity of the formation.

You have to know that this ancient killing formation would frighten even Feng Aotian, who is at the peak of the Great Sage. It can even be said that even the powerful Emperor cannot do anything about it.

He was just a small cultivator in the Wanfa Realm back then, but he was able to make such a terrifying killing formation ineffective by relying on his immunity to formations.

All I can say is that this formation-immune body is completely like a buff.

And after this investigation, Zhong Qing was almost certain that the ancient formation surrounding the Fallen Immortal Secret Realm was completely ineffective against him.

To him, it doesn't matter whether he has the key or not.

Of course, the key to the Fallen Immortal Secret Realm is something that came out of the secret realm after all.

Besides opening the ancient bronze door, there's no guarantee that the three keys may have other potential uses.

Therefore, Zhong Qing felt that it was necessary to verify the authenticity.

However, there are many people and eyes around this Fallen Immortal Secret Realm. In order to avoid causing unnecessary trouble, it is necessary to arrange some measures before verifying the authenticity.

While thinking.

Zhong Qing flipped his hand casually, and a formation diagram appeared in his hand.

This is the Qiankun formation diagram.

Over the years, Zhong Qing has obtained countless treasures from the system.

This Qiankun Formation Diagram is one of the many treasures.

It is an imperial weapon, with a self-contained space inside that can separate the sky and the earth within its range.

Of course, for Zhong Qing, who owns a small world, its so-called defensive function is useless.
