After flying for more than a month, Wang Changsheng and his party came to the sky over an oval-shaped island.

The area of this island is not very large, the radius is more than 100 li in size, there are many hills and soil slopes on the island, and there is a lake of several acres in the center.

Wang Changsheng let go of his divine sense and swept the entire island, but he didn't find the breath of other immortal cultivators, in addition, he found that this island didn't even have a single spiritual vein, it was a truly deserted island.

"The cave mansion is here?" Wang Changsheng said with a frown, looking at the island below.

"Well, my father found the cave here at the beginning, but unfortunately my father didn't know anything about the formation, his old man wanted to invite some fellow disciples to come to break the formation, who knew that he was attacked by demon beasts on the way back, and was seriously injured, and he sat down not long after returning to the Great Song Dynasty, and before he died, he told me that this is the cave of the monks of the Dan period, and it is very likely that there is a magic weapon of the monks of the Dan period," Chen Feng nodded with a smile and said slowly.

"When we get here, Senior Brother Chen can tell us where the cave mansion is!" said the blue-shirted young man lightly.

"It's just under the lake in the middle of the island," Chen replied with a smile.

Hearing this, the blue-shirted young man nodded, and controlled the yellow flying boat to land near the lake in the middle of the island.

Seeing this, Wang Changsheng also urged the snow wind boat to land.

The lake is surrounded by mountains on three sides, and the water is dark green, making it difficult to see what is happening underneath the water.

The blue-shirted young man raised his sleeves, and three blue short swords flashed out, and after one circled, he slashed towards the lake.

I saw three blue short swords slashing at the lake, and I didn't find anything abnormal.

"Senior Brother Wang, please release your black-scaled Jiao and let it suck up the water in this lake, so that we can break the formation. Chen Feng said to Wang Changsheng with a smile.

Wang Changsheng nodded, slapped his palm on the spirit beast bag on his waist, and Xiao Hei suddenly flashed out in the billowing black qi and hovered above Wang Changsheng's head.

"Go," Wang Changsheng pointed at the lake.

Xiao Hei shook his head and tail, and flew towards the lake, and when he reached the sky above the lake, he opened his bloody mouth and sucked it suddenly, and the lake water continued to fly into Xiao Hei's mouth.

It didn't take long for Blackie to drain the water from the lake, revealing the silt-covered bottom.

Wang Changsheng let go of his divine sense and swept the entire bottom of the lake, but he didn't find any forbidden fluctuations, he frowned, and turned his head to look at Chen Fengxiao.

The three young men in blue shirts also moved their eyes to Chen Fengxiao, their eyes full of confusion.

In this regard, Chen Fengxiao did not explain, walked forward quickly, jumped into the bottom of the lake, and after turning around, he stopped next to a one-man high boulder.

"Senior Brother Wang, Senior Brother Zhou, you all come down and help me push away this boulder, this boulder is a starting mechanism, push it open to see where the prohibition is," Chen Feng shouted at Wang Changsheng and the others with a smile.

Hearing this, Wang Changsheng and the blue-shirted young man jumped into the bottom of the lake and came to Chen Fengxiao's side.

The boulder in front of them weighed at least a thousand catties, and although they were immortal cultivators, their strength was really not much.

"Let me come!" Wang Changsheng took the initiative to ask.

Seeing this, Chen Fengxiao and the blue-shirted young man had a flash of surprise in their eyes, although they didn't quite believe that Wang Changsheng could push this boulder alone, they still obediently stepped aside.

Wang Changsheng strode in front of the boulder, took out a giant power talisman and slapped it on his body, and then his lips moved slightly, and a layer of golden light appeared close to his body.

After Wang Changsheng let out a loud shout, his hands suddenly pushed towards the boulder in front of him.

Hearing a "boom" sound, the one-person-high boulder moved backwards little by little.

When Chen Fengxiao and the others saw this, their faces showed joy.

After Wang Changsheng pushed the boulder to move a foot, he couldn't push it anymore.

Wang Changsheng raised his eyebrows, and just as he wanted to ask Chen Fengxiao about it, the ground began to shake violently.

Seeing this, Wang Changsheng was shocked, and hurriedly took out a flying talisman and slapped it on his body, the blue light flashed, and a pair of cyan wings the size of zhang grew behind him, and with a light fan of the cyan wings, Wang Changsheng took off into the air and stopped in mid-air.

Chen Fengxiao sacrificed a cyan shell and flew into the air carrying the blue-shirted youth.

After a few moments, the bottom of the lake stopped shaking, and after a bang, the bottom of the lake cracked, revealing a large black hole, faintly blown by a cold wind, and a bluestone staircase deep into the ground.

"Organ?" Seeing this, Wang Changsheng's eyes flashed with surprise, he said how could there be no prohibition on fluctuations, it turned out to be an organ.

"Let's go! According to my father's last words, the cave is down there," Chen Fengxiao saw this big cave, his face was happy, he quickly landed down, and walked down with a piece of moonstone.

Seeing this, Wang Changsheng hesitated slightly, landed down, and walked down.

The blue-shirted young man and the two nuns then walked down.

The hole was very deep, and after walking for more than a quarter of an hour, Wang Changsheng and the others walked to the end of the stone steps.

At the end of the stone steps is a stone chamber of more than ten zhang in size, and the whole stone chamber is empty and nothing else.

On the stone wall facing the bluestone steps, there is a golden light cover, on which a large number of bean-sized Buddhist texts are circulating.

"King Kong Trapped Demon Array," Wang Changsheng said in a lost voice when he saw the golden light shield on the stone wall.

"Senior Brother Wang, do you know the prohibition here?" Chen Fengxiao asked with some surprise.

"I've gotten some Buddhist cultivation classics before, and there are some Buddhist magic circles that are prohibited, but I also remember one or two, this Vajra Trapped Demon Array is one of them, but most of this array is used to seal high-level demons, I'm worried that there is a high-level demon sealed inside, if we break the formation, it will undoubtedly release the demons inside, and then it will be troublesome," Wang Changsheng said with some worry.

Hearing this, the blue-shirted young man showed a look of hesitation on his face.

"Senior Brother Wang, although the Vajra Trapped Demon Array is a Buddhist magic array, it doesn't mean that there must be a high-level demon sealed inside, it may also be the sitting cave of a high-ranking monk, and besides, maybe other high-level monks covet the defensive power of this array, and it may be that they deliberately set up this array outside the cave," a woman in a blue dress stepped forward and retorted.

"What if there is a high-level demon printed on it?" Wang Changsheng said with a frown.

"Senior Brother Wang, don't worry, there are no demons in it, but the cave mansion where the Taoist monk Jin Yue Zen Master sits, this is what the father of the family said to the younger brother," Chen Feng explained with a smile.

"Zen Master Jinyue, why have you never heard of this person?" Wang Changsheng raised his eyebrows when he heard this, and said suspiciously.

"There are a lot of high-level monks in the Xingchen Sea, it is impossible for us to know the names of all the high-level monks, and besides, people in the Buddhist sect rarely show off in the market, most of them are cultivating in the cave, and it is normal that we have not heard of Zen Master Jinyue," the blue-shirted young man said disappretently.

"I hope so!" Hearing this, Wang Changsheng's face softened, and he said lightly, with a hint of worry in his eyes.

I don't know why, he always felt a little uneasy.

"Since everyone has no opinion, let's break the formation together! Even if it is a Buddhist formation, after so many years, the power is definitely not as good as before, the five of us will shoot together, spend a little more time, we should be able to break this formation," the blue-shirted young man urged, after speaking, his sleeves flicked, and three blue short swords flashed out.

"Wait, let me lay out a magic circle, so as not to cause the cave to collapse due to our attack," Chen Fengxiao said when he saw this, and hurriedly stopped the blue-shirted youth.
