“Azu, look, there is a strange bird there!” Pei Mianman pointed to a place in the middle of the stone gate, “Maybe the mechanism to open the door is here.”

Zuan actually noticed that there was a pattern of a strange bird in the center of the stone gate, with red all over the body, shaped like a phoenix but not a phoenix, and like a peacock but not a peacock.

It looks a bit like his summoning beast "Baiming".

Zuan's heart moved and hurriedly summoned the Baiming and directed it to approach the strange bird pattern. Unfortunately, no matter how it flew around or how it sang, there was still no reaction on the stone gate.

However, as the sound of Baiming's screaming spread, the red light in the eyes of the skeleton warrior kneeling beside the steps not far away gradually dimmed. Unfortunately, this scene was not seen by Zuan and the others.

"It didn't work?" Zuan frowned and was disappointed.

He suddenly remembered the records about the Shang Dynasty in the previous documentary. The ancestors of the Shang Dynasty were called Qi, "The daughter of the priest named Jian Di, who swallowed the eggs of the Xuanbird and gave birth to Qi." Therefore, the Shang Dynasty regarded the Xuanbird as a totem. I guess this bird was their totem Xuanbird. So what does the Xuanbird here represent?

While he was pondering, Pei Mianman, who was beside him, suddenly made a new discovery: "Hey, the pattern of this bird is a bit strange. The stones around it seem to be able to move, and there seems to be some grids in the center of the bird."

Zuan was stunned and hurriedly looked at it. Then he found that there were indeed two horizontal and two vertical lines on the Xuanbi pattern, which divided the entire Xuanbi pattern into nine small grids.

At the same time, there was a circle of strange symbols around. Pei Mianman tried it. The small squares with strange symbols could slide into the nine small squares in the middle.

"One, two, three..." Pei Mianman counted and said in surprise, "There are exactly nine signs engraved. It seems that the door should be opened by putting these squares into the corresponding position."

"Yes, Manman, you have observed it very carefully." Zuan came to the door and looked at the nine stones around him in a daze. He had thought too much before and went astray. He was not as pure as Pei Mianman, so he discovered these clues, "But what do these symbols mean? Have you seen them before?"

"No." Pei Mianman shook his head and pondered about the things he had learned. "I have never seen any race in the literature of this kind. Speaking of which, the style of these symbols is somewhat similar to the two words on the stone tablet before."

"Is that right?" Zuan was stunned and hurriedly checked again. Now that she was reminded, the strange patterns gradually became famous.

Since it is related to oracle bone inscriptions, then these nine numbers, plus these nine squares, he can easily think of the mysterious Hetu Luoshu in Chinese history, including a famous song: "Wear nine and walk one, three on the left and seven on the right, two and four on the shoulders, six and eight on the feet, five on the inside."

Simply put, each row and column of these numbers are 15.

It is very simple to fill in these numbers. People with a little bit of mathematical foundation will do it, but the problem is the surrounding squares

(This chapter is not finished, please turn the page)

It is different from the numbers he is familiar with. He can't tell which pattern corresponds to which number.

There are four patterns that are relatively easy to recognize, namely "one horizontal line", "two horizontal lines", "three horizontal lines", and "four horizontal lines", which should correspond to "one, two, three, and four".

But the other ones are hard to recognize. For example, there is a symbol like a trident with a curved tail, a symbol like a "human"-shaped roof, a symbol with a "X" in the middle, and a horizontal seal on the upper and lower sides, like a folding stool or a spring bed like Marioli, and a symbol like ")(", like a pair of brackets in the order of change.

The strangest thing is another symbol, a cross.

Zuan subconsciously thought it was a "ten", but then he overturned this when he thought about it. After all, there is no number 10 in the nine-clide grid.

He was full of regret. If he had read more oracle documentaries, he might have known these words himself.

I don’t know how the archaeologists learned about these ghost painting talismans back then.

etc……

He suddenly had a flash of inspiration in his mind. He remembered that the reason why Chinese culture was passed down in line is that people thousands of years later could recognize the words written by their ancestors thousands of years ago.

The reason why I know it is mainly because the words have evolved from generation to generation.

The characters in later generations mainly evolved from the small seal script of the Qin Dynasty, and the small seal script also had some shadows of oracle bone inscriptions.

In this case, oracle bone inscriptions should have a related relationship with those characters in later generations. It would be fine to have complex oracle bone inscriptions. Now, even though you know that these oracle bone inscriptions represent numbers 1-9, you should be able to find clues if you slowly turn them back.

He looked at the trident icon with a bent tail, and his head kept turning, observing from various angles.

Suddenly, he found that he pulled the head of the trident down and let the entire trident flatten. Isn’t it exactly the left half of the “Nine”? The curved tail behind the trident is exactly the hook on the right side of the “Nine”.

Does the pair of reverse brackets look similar to the "eight" shape?

Hey, if this is eight, what is the shape of the character "human"? It also looks like eight? Is it the two points below six?

Then there are only five and seven left. The "ten" symbol is not very consistent with "five" no matter how you look at it.

So is the symbol of the spring bed five?

He tried to twist the "X" between the two horizontal lines of the spring bed in his mind, and it seemed that it could really turn into a "five" shape.

Then the "ten" is seven, and the difference between the two is that there is an extra hook.

Zuan checked again and found that although his reasoning was somewhat logical, it was not without loopholes. For example, if the four horizontal lines do not represent the four, many of the reasonings later would be wrong, or even that one.

(This chapter is not finished, please turn the page)

Eight and Six, he wasn't sure if he had done it right.

He was about to verify it again, but at this time, a "whip-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y-y

"Azu, what should I do?" Pei Mianman looked at Taotie who was looming in the thick fog, and his hands lingered in black flames, and was obviously ready to enter the battle.

But with so many Taotie, the two of them are most likely in danger.

Zuan didn't have time to think about it anymore, and directly moved each character to the corresponding position according to the inference just now.

This door is designed in an extremely exquisite manner. The grid marked with two lines on each horizontal and vertical lines is just a groove that pulls the surrounding character blocks to slide.

When he slid the last character in, a golden light shone out from the nine characters, and then the golden light extended, filling the gap between the two doors one after another, and then surrounded the two doors with golden light along the outlines of the upper and lower sides.

Click~

Flashes of gear swelling sounds came from inside, and then the two doors slowly opened.

Pei Mianman looked at Zuan with shock: "Azu, I really admire you more and more now. Can you even crack such a difficult mechanism?"

She was always smart, but just now she looked at those strange patterns and was clueless.

"Haha, you will know that there are many powerful things on me in the future." Although Zuan spoke very proudly, he still secretly cried out ashamed in his heart. The reason why he was able to solve this mechanism was mainly because he took advantage of time travelers. If he had no knowledge in his previous life, he would not be able to think of it even if he wanted to break his head.

"Smelling and beautiful~" Pei Mianman's beautiful eyes were flowing, thinking that Chuyan didn't know why he could see his extraordinaryness in advance, but now she didn't have time to think about these things, so she pulled Zuan and ran into the stone gate, "Taotie is about to catch up, let's go in first!"

After the two ran into the door, they subconsciously wanted to lock the stone door again and shut Taotie out. Unfortunately, they used all their strength to suck it out and still couldn't close the stone door.

Now that time is urgent, they have no chance to find the closed agency anymore, so Zuan had to pull Pei Mianman into it.

"Hehe!" A Taotie howled and came to the steps. Just as he was about to pounce into the stone gate, a cold light flashed by, and its body suddenly froze.

The tall and burly skeleton warrior next to him slowly stood up from the ground, and a drop of blood slowly dripped from the long spear in his hand to the ground, making a slight sound.

Then the frozen Taotie trembled and his huge head slowly slid down from his neck.
