In this dark underground palace, the curve of time was infinitely extended.

Initially, Fang Zishu and the others could still rely on the phone that Xiao Hui was carrying to determine the specific time and place.

However, as the battery on Xiao Hui's mobile phone ran out, the concept of time became more and more inappropriate.

Initially, Fang Zishu wanted to use the 'Heavenly Star Wind Water Technique' to determine the approximate time by observing the changes in the Seven Stars of the Northern Dipper and the stars in the sky. However, after he fell into the 'Nine Palaces Eight Trigrams Formation', not to mention using the 'Heavenly Star Wind Water Technique', he couldn't even see a single constellation. In this situation, Fang Zishu wasn't able to determine the exact time, but in order to facilitate the date calculation, Fang Zishu proposed to use his meal as the time unit.

Of course, this was only a rough estimate of time. In this gloomy underground palace, for the sake of calculation, he had taken a compromise of time.

That is, the time between the first growl of the stomach and the second growl, 7 hours.

The two meals meant that Professor Xu was resting for 14 hours.

After obtaining an accurate answer, Professor Xu did not bother to continue studying the inscriptions on the monolith, and turned his attention to the huge mountain wall behind the monolith. After many times searching, he discovered that this place seemed to have been transformed from a natural cave, so the appearance of these mountain walls was extremely abrupt.

Other than these, the book also discovered that outside of the protruding part of the stone wall, there were a few other ancient diagrams. This drawing seemed to have been baptized over a long period of time, and had become mottled and blurry.

"Qi Sanpang, you came to take a look at this thing?"

Fang Zishu waved to Qi Sanpang, who was resting against the cliff. He then took out a highly focused flashlight from the backpack that he carried around with him.

Ding!

The moment his finger pressed down on the switch, a pale ray of light broke through the binding force of the night and shot towards the blurry image on the mountain wall. Under the light of the flashlight, the book felt more mysterious as it looked at the indistinct patterns on the cliff.

"Brother Fang, what's wrong?"

Qi Sanpang yawned, with a drowsy look on his face.

"Qi Sanpang, look over there with my flashlight. What is that pattern on the cliff?"

With Fang Zishu's reminder, Qi Sanpang immediately looked towards the source of the bright light.

Very soon, Qi Sanpang saw the pattern mentioned in the book.

Although it was very dark, Qi Sanpang could clearly see the shape of the pattern under the light of the high-intensity flashlight. The mottled pattern was about the size of a washbasin, and it was formed by two parts.

On the left was a circle the size of a plate. In the center of the circle, there were four symbols engraved. These symbols were placed in four different directions on the plate. Two of them were facing each other.

On the right side of the disc, there was a 'Fecal Fork' carved into it. No, it should be said that it was very similar to the 'Trident' held by the 'Sea God Poseidon' from ancient Greek legends. That weapon looked like a 'Trident', and was currently slanted at that huge disc.

"Qi Sanpang, can you see what this pattern represents?" Fang Zhisu asked.

Qi Sanpang shook his head slightly, "Isn't this pattern too simple to engrave? Furthermore, we are now in the middle of the night, and even though there is a flashlight to provide us with some light, at such a distance, we are still unable to see if there are any other patterns between the disk and the trident."

After pausing for a moment, Qi Sanpang continued, "For now, the pattern is made up of a silver white disk, four symbols and a weapon on the right that's similar to the 'trident'. I know all three if I look at them separately, but once I combine them together, I won't be able to figure out the meaning behind the engraver's performance."

Fang Zishu's view was almost the same as Qi Sanpang's, but he had a feeling that the strange pattern on the cliff wall must be hiding a huge amount of information. However, the current him had yet to discover the connection between these few people.

"Looks like I have to ask Professor Xu. He's an expert in archaeology, perhaps he knows this weird thing!"

Thinking of this, Fang Zishu turned around and walked over to the stone monument.

At this moment, Professor Xu was once again studying the Pre-Qin script on the monument with Da Ceng's help. From the connection between the characters, he began to repair the individual 'small charms' that had been corrupted by nature and became blurry.

"Professor Xu?" Fang Zishu called out softly.

"Master Fang, didn't I tell you earlier?" We'll leave after two meals. Don't be in such a hurry. The saying goes, 'The body is the core of the revolution'. Earlier, when you were continuously attacked by the 'Red Stone Green Feather Bat', your body suffered many injuries.

He immediately explained, "Professor Xu, I didn't come here to rush you. When I was bored, I once again searched the cliff face, looking for something new, and in the end, I found an ancient pattern on the western side of the cliff. The pattern on the west side of the cliff had become mottled after the erosion of time, and even after looking for a long time, Qi Sanpang and I still couldn't figure out what that pattern was trying to convey, so I came over to ask you to take a look at that pattern!"

"So that's how it is!"

Professor Xu nodded, putting down the magnifying glass in his hand. "Bring me over to take a look."

Soon, Professor Xu arrived at the cliff as well.

Under the guidance of the book, Professor Xu also saw the extremely ancient pattern on the cliff.

Unlike Fang Zishu and Qi Sanpang, Professor Xu immediately exclaimed in surprise when he saw the ancient pattern. "This …" Here... How could there be such a thing here? "

Hearing Professor Xu's words, Fang Zhoushu knew that Professor Xu must have recognized the origin of the item, or else he would not have shown such an expression. "Professor Xu, looks like you know this thing?"

Professor Xu said slowly after a moment of silence, "Rather than saying it's a pattern, it's more like a totem!"

"Totem?"

Fang Zishu was stunned, he did not understand the meaning behind Professor Xu's words. "So these simple strokes are totems?" This... Isn't this a bit too hasty? Also, if this pattern is a totem mark, can you tell me what exactly this totem represents? "
