Bu Wendong only guessed half right, and what trapped them at this moment was indeed not an ordinary fourth-level formation, but a powerful fourth-level peak formation, known as the Ten Thousand Miles Mist Great Array. And Ying Tianfeng and the other four Yuan Infant powerhouses were not wantonly slaughtering the disciples of the Cangyun Sect at this time, in fact, they had no way to make a move at all. Because they were not only facing the four-level peak formation of the Ten Thousand Miles Mist Great Array, but also being fiercely attacked by another fourth-level peak killing array, the Beacon Fire Live Killing Array.

Tu Penghai was only a fourth-level mid-level formation master, and he couldn't arrange a formation at this level.

In addition to Tu Penghai, the only one in Cangyun Sect who can arrange a fourth-level formation is Cao Fan.

If it was three months ago, Cao Fan would only be a fourth-level early formation master, and he would also not be able to lay out a fourth-level peak formation. It's just that during this period, he secretly went to the Floating Boiling Sea again, and when he came back, he immediately organized people to start arranging new formations.

From Gong Borong's mouth, Cao Fan learned that Luo Daozong was ready to dispatch the two Supreme Elder Phantom Spirit Son and Shen Zhenzi. Regardless of whether Gong Borong can return or not, Luo Daozong is bound to launch a sect war against Cangyun Sect.

The two powerhouses in the late Yuan Infant period, this was already far beyond the limit of what Cao Fan could resist. If the other party really attacks, I'm afraid that the Cangyun Sect will really cease to exist.

To resist the invasion of the strong, the formation is undoubtedly the most effective auxiliary means for the defender. However, the Great Array of the Cangyun Sect Protector Sect is only at the level of the early stage of the fourth level, if the Luo Dao Sect also sends a monk army to attack with it, the large array will inevitably be broken, and the entire sect will probably be in calamity at that time.

In this case, Cao Fan secretly sneaked out of the sect the next day after returning to the Cangyun Sect.

His destination was a boiling sea!

If you want to improve your formation cultivation in a very short period of time, the mysterious palace in the boiling sea is indeed the most ideal holy place.

It's just that the risk of doing so is also very huge, in case Cao Fan can't complete the task of the realm elder, he will have to be trapped in the realm of the painting until he runs out of life and dies like Tu Penghai.

However, at this time, Cao Fan had no choice, either to improve his formation cultivation as soon as possible, or to watch the Cangyun Sect be completely wiped out in the Southern Regions.

He had to take that risk.

Re-entering the floating and boiling sea, the scorching heat of the sea water no longer posed any threat to Cao Fan. Soon he re-entered the mysterious palace with ease.

In an instant, he was once again sucked into the realm of painting.

The reason why Cao Fan is so obsessed with improving his formation cultivation here is because there is a powerful prohibition of the law of time in the middle of the painting, and all the monks who enter it are in a state of stagnation during the middle of the painting. As long as you can pass the test of the elders, when you come out, it will still be the time when you first came in.

That's what he wants!

To Cao Fan's surprise, the realm in the painting is much more demanding for the clearance of those who enter it for the second time. He studied the formation path for four whole years inside, but he was never able to pass the requirements of the realm elders.

In the assessment of the formation realm, every time you fail, the next test will further increase the difficulty. Tu Penghai, who had been extremely cultivated in the formation at the beginning, was also lost in it because of this, and he couldn't get out.

After the third failure, Cao Fan knew that he had taken it up. The realm in the painting is not a place where he can come and go whenever he wants.

When he came, he was full of confidence, thinking that with the help of the simulated formation of the formation and the time dividend, he could pat his ass and walk away after breaking through the formation path cultivation. Unexpectedly, the Realm Elder actually raised the difficulty of passing the level to an almost impossible level, and even if he had already raised his formation cultivation to the realm of a fifth-level formation master, he still couldn't overcome the difficulties set by the Realm Elder.

He has the Primordial Teleportation Crystal, so he doesn't have to worry about being trapped in the Array Realm forever, and he can teleport back to Earth at any time. But this doesn't mean anything at all, Ke Ying is here, Xiaochuan is here, his comrades-in-arms are here, and more than 200 people from the Cangyun Sect are waiting for him to save them. He doesn't have the right to be trapped in the middle of the picture!

Cao Fan, the test of the elder, determined that he would not be able to pass with his current level. And the longer he stays in the painting, the more perverted the tests he faces, and the less chance he has to complete them.

He had to push his limits, or he would have to be stuck here forever.

A gray vial that exuded a rich and simple atmosphere was taken out by Cao Fan from the Taishang Nine Realms and held it in the palm of his hand.

This is a gas cylinder.

This treasure is one of the three treasures that were publicly rewarded with a rich reward when the Water Mirror Maze Valley opened that day, or rather, it is the most precious of the three treasures.

Cao Fan coincidentally killed the puppet man Moluo puppet who wanted to refine him into a human puppet, and got a Qiankun gas cylinder when he killed his Yuan Baby. Since then, he has been carefully storing it and has never been willing to take it out and use it.

Even if he died nine times when he built the foundation, he didn't think about using this treasure.

The Qiankun cylinder contains the vitality of the beginning of heaven and earth. Every time it is opened, the absorber of Qiankun Yuan Qi will be able to break through in defiance of all the rules of heaven and earth and the shackles of cultivation. Because of this, Luo Puppet was able to miraculously break through to the Jindan Stage and the Yuan Infant Stage under the suppression of the Heaven and Earth Rules of the Water Mirror Maze Valley.

The benefits of Qiankun Vitality go far beyond that. Every time a monk absorbs a wisp of Qiankun vitality, the spiritual root qualification and comprehension will also be greatly improved. It was precisely because of this that Cao Fan thought of it when he was in a desperate situation.

There were twelve wisps of Qiankun vitality in one cylinder, but unfortunately two wisps were used up by Luo Puppet back then, and each of them was extremely precious.

Cao Fan originally planned to use up a wisp when he got married, but now he doesn't have to be afraid.

There was no movement after the Qiankun gas cylinder was opened, but Cao Fan was not worried, but cast a spell according to the magic trick engraved on the bottle, and after a stick of incense, a wisp of milky white gas finally floated out from it.

Cao Fan immediately closed the mouth of the bottle, opened his mouth and sucked it violently, almost swallowing this precious wisp of Qiankun vitality directly.

Then his limbs suddenly clicked, and the whole person quickly entered a state of emptiness.

If someone saw Cao Fan at this moment, they would find that the momentum of his body was climbing rapidly, and his eyes showed a look of enlightenment.

Cao Fan's cultivation broke through all the way from the second floor of the foundation, with three layers of foundation, four layers of foundation, and five layers of foundation......

What kind of Dharma cultivation potential value was no longer a problem at this moment, because this value had also been greatly increased as he inhaled this wisp of Qiankun Yuan Qi.

Cao Fan's spiritual root qualifications, refining potential value, and even sea knowledge have all been greatly improved and enhanced.

At the same time, he is also advancing by leaps and bounds, as well as his formation cultivation.
