The two of them flew slowly down the corridor of the cave towards the depths.

Along the way, Shi Sheng couldn't help but secretly feel frightened, here, the pearl of the North Sea was as worthless as the pearl of the night, and it was inlaid everywhere on the stone wall of the corridor.

There are also some small pendants in the small compartment on the stone wall, but these small pendants are not extraordinary, but some top-level magic weapons, which are casually placed here as works of art.

Shi Sheng couldn't help but be secretly frightened, how much net worth does the owner of this cave have? And what makes Shi Sheng strange is that this cave also has a suppressive effect on perception, and can only perceive not far away, and if it is too far, it will be vague.

It didn't take long for the two of them to find a stone gate in front of them, which was also inlaid with dense North Sea pearls, but if they looked closely, the beads seemed to have some kind of pattern.

"Formation?" Shi Sheng frowned.

"It's such a big deal, even our palace is not so luxurious, Brother Shi Sheng, what kind of place is this?" Zhu Xiaohan wondered.

"I said it's the underwater palace of the Dragon King of the North Sea, do you believe it?" Shi Sheng said casually.

"Beihai Dragon King, won't you? Didn't Beihai be swallowed up by the East China Sea Demon Clan before it dried up? Although I haven't experienced it, I've also heard my father talk about it, so I can't produce Beihai Pearls anymore, which makes Beihai Pearls so precious!" Zhu Xiaohan wondered.

"The North Sea is dry, isn't it??Is there really an old dragon king?" Shi Sheng touched his nose speechlessly.

"I don't know if there is a dragon king of the North Sea, but back then, the North Sea Demon Clan was said to be more powerful than the East China Sea, but then the years changed, the North Sea gradually dried up, and the Heavy Water Demon Clan gradually fell. In the end, it was annexed by the East China Sea!" Zhu Xiaohan said.

"I see!" Shi Sheng nodded, but this is only a small Dongtian Lake, and it can't be connected to the Beihai, so it is quite surprising that there are so many Beihai pearls.

"Brother Shi Sheng, can he break the prohibition above?" asked Zhu Xiaohan.

"It seems to be a ban, and it is said that this prohibition is to complete the missing stumps. Only when the pattern is complete and perfect can the ban be opened, but the ban should have been lost for tens of thousands of years, how can it appear here?"

Shi Sheng was a little puzzled, even Lin Wan'er's formation chapter, as well as the formation chapter that Bai Ming obtained in the Broken Soul Valley, only recorded some general introductions to the diagram ban, but there was no detailed arrangement method, and there was no detailed method of cracking.

"It's the first time I've heard of it. It looks quite interesting, this North Sea Pearl is pieced together, it seems to be a landscape painting, but it is not completely, it is very vague, and if you look closely, it looks like a sea monster, and I don't know what the pattern is. By the way, Brother Shi Sheng, if you put it together wrongly. What will be the consequences?" Zhu Xiaohan asked.

"This ...... I don't know very well, the record of the picture ban is too vague, anyway, let's be careful!" Shi Sheng said with a frown.

"No wonder there are so many beads on the stone wall of the corridor, it turned out to be left for future generations to break the ban, so I will collect some Beihai pearls on the stone wall first!" Zhu Xiaohan said.

"Wait!" Shi Sheng waved his hand: "Forget it, use what I got from Sangouzi before." lest you inadvertently touch other prohibitions!"

Shi Sheng didn't know that this small move avoided a lot of trouble, and took out those Beihai pearls picked up by the three dogs, Shi Sheng and Zhu Xiaohan began to carefully examine the patterns on the stone gate.

It took a lot of incense. Shi Sheng frowned, and found that what Zhu Xiaohan said was right, the group on it did look like a landscape painting at first glance, but after careful observation, he found that the pattern looked like an abstract demon beast shape.

"It's going to be difficult, we can't mess around, Xiaohan, what do you think you think of this picture?" Shi Sheng asked.

"Both are alike!" Zhu Xiaohan immediately shook his head: "Both are not quite alike!"

Shi Sheng was a little speechless!

"Could it be a picture-in-picture?" Shi Sheng's eyes lit up, and a flash of inspiration suddenly flashed in his mind.

"What is a picture-in-picture?" asked Zhu Xiaohan.

"Beneath a perfect picture, there is another pattern hidden, which can only be seen if you look carefully. Shi Sheng said excitedly.

The so-called picture-in-picture, such as Picasso's 'Blue Room', which appears to be a picture of a woman bathing, but hides a portrait of a man, or the scroll that is marked 'Mona Lisa's smile', and a figure resembling a human head is hidden under the left shoulder, which is said to be some kind of symbol.

In fact, some famous painters may have a picture-in-picture, but it has also been discovered in recent years, and few people will notice the abstract and vague patterns before, and sometimes they can only use instruments to restore the whole picture of the hidden patterns.

Thinking of this possibility, Shi Sheng had the confidence in his heart, as long as he perfected the surface landscape painting at the same time, and completed the abstract demon beast form, then the ban could be opened.

Of course, this matter is simple to say, but it is difficult to do, because inlaid with a North Sea pearl should not only be helpful to landscape painting, but also not affect the abstract painting of the monster shape, that is, a North Sea pearl, to play two roles without affecting each other.

"It doesn't look like the picture-in-picture of some masters, but you can crack it in this way!" Shi Sheng first looked at the landscape painting carefully, and after more than half an hour, he firmly remembered it.

In the end, Shi Sheng carefully looked at the abstract painting, and after more than an hour, Shi Sheng also remembered the vague general shape of the demon beast in his mind.

Immediately afterwards, Shi Sheng closed his eyes, and constructed a picture of landscape painting and demon beast form in his mind, trying to put the pearls of the North Sea one by one, and complete the two patterns at the same time.

Sometimes press and put a few beads on it, and the landscape painting is flawless, but I find that it is not very harmonious with the hidden monster shape, and I have no choice but to remove a few beads and complete the monster shape, but I find that the landscape painting has changed its imperfect appearance.

After countless failures and countless attempts, Shi Sheng was not discouraged at all, and sat cross-legged on the ground like this, looking like he was meditating and pranayama.

Zhu Xiaohan didn't bother, he sat very patiently on the side, sometimes looking at the pattern on the stone door, sometimes holding his chin with both hands, carefully looking at Shi Sheng who was thinking seriously, and occasionally, Zhu Xiaohan's face would show a sweet and happy smile.

Three days later, Shi Sheng's eyes suddenly opened, and he looked at the stone gate pattern with a smile!

"Brother Shi Sheng, has a way, then do we want to complete the landscape painting, or complete the somewhat vague demon beast form?" Zhu Xiaohan asked with a happy face.

"Complete together!" Shi Sheng's eyes were full of confident smiles, and Zhu Xiaohan was slightly stunned, he had never heard of such a painting style, which could display two different patterns at the same time!
