"Senior Wentian, do you know this formation?" Xu Nian asked Demon Lord Wentian via voice transmission.

"Boy, this formation is called the Qiankun Heaven Locking Formation. It is a large formation. Once activated, a large amount of spiritual energy will be consumed. This formation can be used both defensively and offensively. It has reached the peak level of a low-grade spiritual formation."

Demon Lord Wentian said.

"Qiankun Heaven Locking Formation? Does that senior know any way to break the formation?" Xu Nian asked.

This imperial capital formation must be destroyed.

If it is not eliminated, then even if he is not afraid.

But Xu Xin and others can't.

Moreover, they cannot leave the imperial capital without breaking this formation.

Because once the formation is activated, the people inside will never want to leave again.

So if you want to get out, you must break this formation.

"It's difficult to break this formation, but it's not impossible." The voice of Demon Lord Wentian sounded.

"Is there any way?" Xu Nian was immediately delighted.

What he fears most is that there is nothing he can do.

Now that he heard that Demon Lord Wentian said there was a way, he was naturally very happy.

"Boy, don't be too happy first. Although I said there is a way, it is not easy to do. You may even lose your life if you are not careful." Demon Lord Wentian replied.

Xu Nian nodded.

He also knew that with his current strength, it was simply impossible to deal with such a formation.

Unless the sword takes a sideways approach and the soldiers make dangerous moves.

"Boy, I have two methods for you to choose now. One is relatively easy, and the other is very dangerous. The choice is up to you." Demon Lord Wentian said.

Xu Nian said nothing and continued to listen.

"The first is to use the Earth God to swallow the sky and attack the imperial city. The center of the formation source is the underground of the imperial city. As long as the formation source is destroyed, the formation will be self-defeating. But in this way, you will

We are facing a head-on war with the imperial family." Demon Lord Wentian said.

Xu Nian fell silent.

He is not afraid of a head-on battle with the imperial family.

In fact, he had already thought about it on the way here.

He knew that even if he didn't cause trouble to the imperial family this time, the imperial family would not let him off easily.

Xu Nian was ready for a complete war.

However, the use of Earth God Swallowing Heaven has strong side effects.

Once it is used, I am afraid that in the end it will be at the mercy of others.

So this method is undoubtedly very risky.

"The second method is to devour!" Demon Lord Wentian replied.

"Swallow?" Xu Nian asked in surprise.

"Yes, Devour. Since this formation is maintained by the spiritual energy of heaven and earth within the Imperial Capital, then you should use this opportunity to absorb the spiritual energy of Heaven and Earth in the Imperial Capital. In this way, not only can you improve your own cultivation, but you can also break through the great formation.

Array, when your devouring speed exceeds the energy accumulation speed of the great array, the great array will collapse. However, this method is very dangerous, because you are likely to be exploded by the expanding spiritual energy of heaven and earth." Demon Lord Wentian replied.

road.

When Xu Nian heard this, his eyes suddenly lit up.

Swallow the power of this imperial capital formation.

I’m afraid this is really not what most people dare to think about, right?

After all, this is the aura of the entire imperial capital!

How could one person's cultivation speed exceed the spiritual energy absorption speed of an imperial capital formation?

But Xu Nian is different.

Not to mention his own swallowing speed, the swallowing speed of the Immortal Sky-Swallowing Beast is very terrifying.

"Okay, then I will go crazy once and devour all the spiritual energy of the entire imperial capital. If I can't maintain the imperial capital's formation," Xu Nian said to himself, with determination in his eyes.

"Whoosh whoosh!"

At this moment, Bing Lan and Xu Yu flew in from a distance.

When Xu Nian saw Binglan and the others arriving, he knew that they had destroyed the Fang family.

"You are here just in time. Take good care of my mother and the others for me and protect their safety." Xu Nian said to Bing Lan and others.

"Yes, Palace Master!"

Bing Lan and others responded immediately.

Then he came to Xu Xin and Leng Yanran.

Seeing this scene, Xu Nian felt relieved.

Then he no longer hesitated and sat down cross-legged.

At the same time, Xu Nian waved his sleeves.

The immortal sky-swallowing beast appeared in front of him.

Everyone around him didn't understand what Xu Nian was going to do.

"What does this kid want to do?"

Even Xuan Hong looked at Xu Nian curiously.

At this moment, his defense has enveloped the entire Kamigawa Temple.

In a short period of time, there is no chance that Kamigawa Temple will be in any danger.

So he was very curious about what Xu Nian wanted to do next.

Xu Nian ignored everyone's doubtful glances.

Instead, he closed his eyes and started to perform the exercises.

"Green Lotus Planted in the Dan Sea" and "God and Demon Body Refining Technique" are cast at the same time.

Suddenly a strong suction force came.

The terrifying suction force directly turned into a huge spiritual energy vortex.

Yes, these two great skills are both very heaven-defying skills.

At this moment, Xu Nian was exerting all his strength. One can imagine how much noise it caused.

"Buzz!"

Suddenly, a huge spiritual energy vortex with a diameter of a thousand meters appeared in the sky.

The spiritual energy around him was directed towards this direction crazily, and finally poured into Xu Nian's body.

"What a terrifying training speed. What kind of battle is the master of the palace practicing? How could it cause such a huge movement of spiritual energy?" Everyone in Shenhe Palace showed surprise.

Undoubtedly, the commotion caused by Xu Nian's practice scared them.

Xuan Hong chuckled lightly.

He had already seen through Xu Nian's thoughts.

But he still shook his head.

This kind of swallowing speed still cannot keep up with the recovery speed of the surrounding spiritual energy.

After all, the imperial capital is not completely closed.

The city gate is wide open, and the spiritual energy is still being replenished into the city.

So he didn't think Xu Nian's swallowing speed could affect the formation.

"Roar!"

However, at this moment, the clone of the immortal sky-swallowing beast let out a roar.

Then everyone saw the immortal sky-swallowing beast opening its huge mouth.

"Buzz!"

Suddenly, a huge suction force came from this huge mouth.

The terrifying spiritual energy was poured directly into the mouth of the immortal sky-swallowing beast.

The spiritual energy vortex in the sky suddenly expanded tenfold.

Suddenly, the aura of the entire imperial capital was aroused at this moment.

A huge spiritual energy vortex with a diameter of almost ten thousand meters appeared in the sky.
