Tu Penghai is a cultivator in the late stage of Jiedan, and even he can't blast through this layer of prohibition, so it can be seen that it is almost impossible for Cao Fan to go out from the entrance.

"It's a pity that I don't have enough materials to arrange the fourth-level formation, otherwise we can try to use a fourth-level killing formation to blast through this layer of prohibition. Tu Penghai sighed and said.

In the more than eighty years of the formation realm, although Tu Penghai has never been able to complete the demanding tasks required by the realm elders, his formation path cultivation has really improved.

He was originally a third-level peak formation mage, and by the time he was rescued by Cao Fan from the middle of the painting, he had already broken through to the realm of a fourth-level early formation master.

The fourth-level formation is enough to pose a threat to the Yuan Infant Stage Great Cultivator. Because of this, the materials for arranging the fourth-level formations were extremely precious, and even for the smallest formations, it was extremely difficult to get the materials needed.

It was impossible for Cao Fan to leave Lu Yuanzhao alone, he could only think about it slowly. Suddenly, his mind moved, and he called through the team channel: "Lao Lu, what are you refining and cultivating now?"

"I'm in the middle of breaking through the realm, and I'll be in touch for a while. Lu Yuanzhao hurriedly replied and then stopped talking. But his tone was one of great excitement and joy.

Cao Fan's method was to let Lu Yuanzhao find this island and then enter this hall.

Obviously, this hall can only be entered, not exited.

The biggest problem now is that Lu Yuanzhao does not have the eye of insight, and it may be very difficult to find this island accurately. As for whether Lu Yuanzhao could withstand the high temperature in the depths of the boiling sea, Cao Fan was not worried at all.

Even if Lao Lu's body refining efforts during this period of time have not made great progress, the sixty points of endurance with the bonus of the mutated Fire-Eyed Golden-Eyed Beast are enough for him to run rampant in the floating boiling sea.

In the following time, Cao Fan and Tu Penghai naturally chatted about the formation path that the two were interested in.

Although Cao Fan did not break through to the fourth-level formation master, he had quite a bit of research on the fourth-level formation. After all, in a heavenly place like the Formation Realm to learn formations, after he had mastered all the third-level formations, every time he learned a little more formation knowledge, it was blood to earn.

The two of them were discussing the fourth-level formation enthusiastically, and before they knew it, two more days had passed. Although Cao Fan was getting closer and closer to the realm of a fourth-level formation master, Tu Penghai also benefited a lot from Cao Fan's formation concept.

After all, Cao Fan was the first person to successfully come out of the formation realm, and the formation ability born from the Heavenly Fortune Creation Technique had a lot to learn from Tu Penghai.

Lu Yuanzhao's message finally appeared in the team channel: "I succeeded in breaking through the realm, refining the realm of the double heaven, haha." Cao Fan, what kind of body refining realm are you?"

"How much stamina attribute did you add?"

"Two times for a total of thirty points. ”

“......”

"What's wrong?"

"It's nothing, I don't want to hit you. Now you swim towards my point of light, and if you find a big island, we'll be able to get out. ”

Cao Fan: Although they opened the Tianyun map here and saw that it was all dark, their teammates would appear in the form of bright spots, which was undoubtedly a good way to guide.

Different body refining techniques have different stamina after breaking through the realm. Cao Fan increased his stamina by twenty points at a time, Lu Yuanzhao increased by fifteen points at a time, and other body refiners might only increase by ten points or even eight or seven points.

At this time, Lu Yuanzhao's stamina reached 60 points, and he stopped at the last few hundred zhang from the island where this hall was located, and he couldn't rush over again.

The gap between his endurance and Cao Fan was 28 points, and in the end, he could only use the Fire-Eyed Beast to sprint.

The latter not only gave Lu Yuanzhao a bonus of 60 endurance, but his vision was not suppressed in the floating boiling sea, but he only carried Lu Yuanzhao to jump in the boiling sea a few times, and jumped on this mysterious island for the last time.

After a few breaths, Lu Yuanzhao rode the fire-eyed golden-eyed beast and smoothly rushed into the main hall. There was no doubt that there was no way for him to get out of the entrance again.

Cao Fan and Tu Penghai were both experts in formations, and it was not difficult to operate the teleportation array in the main hall.

Lu Yuanzhao remembered Cao Fan and Tu Penghai's reminders, and after coming in, he never used his divine sense to check the eight-sided murals. He sent the Fire-Eyed Beast back to the mount interface, and stepped into the teleportation array at the same time as Cao Fan and Tu Penghai.

There was a flash of blue light, and in an instant, all three of them disappeared.

The location of the teleportation is not near the entrance to the Floating Light Boiling Sea, but it is not far from the Floating Light City.

Tu Penghai is considered a native here, and although he has been trapped in the painting for more than 80 years, the terrain in the vicinity is still fresh in his memory. Soon he led everyone into the Floating Light City.

At this time, Tu Penghai had already changed into civilian clothes, and did not show the logo of the Cangyun Sect. When necessary, he will give an unexpected surprise to those forces who vainly seek to be unfavorable to the Cangyun Sect.

Mu Ping has been staying in the inn these days, so naturally there is no trouble to find her. At this moment, seeing the news that Cao Fan and Lu Yuanzhao had returned safely, she casually cleaned up and left the room excitedly.

When Mu Ping went downstairs, someone noticed her all of a sudden.

A stunning female cultivator with low cultivation appeared alone in the inn, even if Mu Ping rented a very regular large inn, it still attracted the attention of two or three groups of people.

It's just that these people have just stood up, and Cao Fan and a few people have already stepped in. The coercion of Tu Penghai's Dan period didn't even come out, which made these people feel deep fear. One of the big men with a lewd face was even more taken care of, and not long after Mu Ping and the others left the inn, he vomited out a mouthful of blood.

This is obviously a female cultivator from a major sect, and there are elders in the sect to protect her. Those who wanted to get into the wrong before secretly shouted luck in their hearts, if they had made further offensive moves just now, they were afraid that they would have already been killed on the spot by the old man in Tsing Yi.

Out of Fuguang City, Cao Fan sacrificed the cloud dragon boat. The flight speed of the gourd magic weapon was too slow, and the space was small, so it was not suitable for hurrying.

At this moment, whether it is Cao Fan or Tu Penghai, they are eager to return to the Cangyun Sect as soon as possible.

The cloud dragon boat flew high into the air, and there were already four more people inside, it was the three elders of Cangyun and Xiahou Nan.

Before they could recover from the joy of escaping death, they noticed that there was an unfathomable powerhouse in front of them.

Soon the three elders of Cangyun recognized Tu Penghai, and the excitement of overjoyed was beyond words. They never dreamed that there were survivors of the sect's Elder Jiedan, which was really meaningful for the revitalization of the Cangyun Sect.

At the same time, a group of people appeared again at the entrance to the floating boiling sea. These people were all dressed in the costumes of the Qingtian Sect, and they were sent by Yu Chiguang to investigate the problem of the shattering of the soul cards left by Pei Chengtian and the others in the sect.

This time, the investigation team sent by Yu Chiguang can be described as a big deal, led by Jiang Yang, the deputy hall master in the late stage of the Jiedan, and there is also an elder Jiao Chengbi in the early stage of the Jiedan, and seven inner disciples in the foundation building period.

"It's weird. Since the three elders of Cangyun have broken into the boiling sea, there is no reason to survive. Who killed Pei Chengtian and the three of them?" Jiao Chengbi looked at the entrance of the floating boiling sea with flickering lights, and turned his head to Jiang Yang and said.

"No matter what happens, I, the foundation building monk of the Qingtian Sect, can't die in vain, this account can only be counted on the head of the Cangyun Sect. Since there is an order from above that the Cangyun Sect cannot be destroyed, then we will kill the two elders of Cangyun first this time, and then get rid of their more qualified monks. Leaving some waste from the Qi cultivation period is not considered a violation of the rules. Jiang Yang said with a cold expression.
