With two Naga missing, Lu Yuan clearly felt that there were some loopholes in the opponent's formation.

The battle lasted another five minutes, and a Naga moved half a beat slower, and Lu Yuan seized this opportunity and speared forward.

"Bang"

Another Naga was knocked out by him, and this time if Lu Yuan hadn't withdrawn three points of force at the last moment, this Naga would have been pierced by a single shot.

After this Naga lost its combat effectiveness, the formation of the Naga was completely destroyed.

Losing the coordination of the formation, the remaining Naga were quickly taken down one by one.

After Lu Yuan handed over the group of nagas to the robot's care, he slowly walked towards the building not far away.

When Lu Yuan came to this building, he stopped. At this time, there was an incredible expression on his face.

He actually found a gossip map on the gate of the building.

As we all know, Bagua was first seen in the Zhou Yi, an esoteric philosophical concept of ancient Chinese culture, which can represent the dynamic and static state of all natural phenomena.

The basis of the formation of the eight trigrams is the image of change, and the basis of the double hexagram lies in the change, and "the line is in it" is the internal motivation of the flow of the Yi Dao.

Each hexagram represents a certain thing, Qian represents the sky, Kun represents the earth, Xun represents the wind, Zhen represents the thunder, Kan represents the water, Li represents the fire, Gen represents the mountain, and Dui represents the Ze.

It is like eight infinite and invisible pockets, which encompass everything in the universe, and when matched with each other, they become sixty-four hexagrams, which are used to symbolize various natural phenomena and human phenomena.

For thousands of years, gossip has been one of the symbols of Zhuxia civilization, and not only that, gossip is generally paired with Taijitu.

Looking at the gossip in front of him, Lu Yuan continued to look for it after experiencing the initial surprise, and sure enough, he soon found a broken Taiji diagram on the other side of the building.

At this time, the sharks hiding in the building were looking at Lu Yuan outside the house in horror, but Lu Yuan couldn't take care of them at this time.

Lu Yuan's mind was completely on Tai Chi and the Bagua Diagram, and he was thinking in his heart about the reason why the Bagua Diagram appeared here.

In Lu Yuan's original knowledge, Bagua represented the philosophical ideas of early China, and in addition to divination and feng shui, its influence involved traditional Chinese medicine, martial arts, music, mathematics, etc.

The innate Bagua diagram is usually paired with the Taiji diagram. Tai Chi and Wu Ji represent the ultimate ontology of traditional Chinese beliefs (Confucianism, Taoism) "Tao".

Bagua is the basis of the Yi learning system, the pre-Qin Yi study is mainly the "three Yi", that is, the Xia Dynasty's Lianshan (Lianshan Yi), the Shang Dynasty's Guizang, the Zhou Dynasty's Zhou Yi, and later generations are familiar with the Zhou Yi, which is divided into the Book of Changes and the Book of Changes.

"Could it be that this is the Xia Dynasty's Lianshan Yi?" Lu Yuan was puzzled by the gossip map in front of him.

However, because even Shanyi and Guizang are actually just legends, no one in this world has really seen them at all, and Lu Yuan is naturally no exception.

The age of this building is naturally not short, Zhou Yi appeared only 3100 years ago, and the gossip map that appeared here obviously cannot be the Zhou Yi gossip that is circulating in the world today.

In order to clarify the doubts in his heart, Lu Yuan began to carefully observe the gossip map in front of him.

In order to find out the difference between the gossip in front of him and the gossip of Zhou Yi, he began to recall the gossip knowledge he had learned in the past.

The first thing that Lu Yuan thought of was naturally the hexagram-shaped memory song.

Zhu Xi's "Zhou Yi Benyi" in the Song Dynasty wrote "Bagua and Elephant Song" to help people memorize hexagrams.

Lu Yuan recalled the contents of it: three consecutive dry, six broken kun, shaking the bowl, covering the bowl, leaving the void, full of the kan, and the lack of the top, and the breaking of the Xun. Types of Bagua: Divided into Innate Bagua, Zhongtian Bagua, and Acquired Bagua.

The five elements of gossip: only the five elements of the day after tomorrow: dry and exchange are gold, kun and gen are earth, earthquake and Xun are wood, kan is water, and separation is fire.

Bagua with the Nine Palaces: There are innate matching, acquired matching, and Taiyi matching.

Although Lu Yuan recalled the content of "Bagua and Elephant Song", these could not help him distinguish the special features of the gossip in front of him.

At this time, he began to recall the legend of the origin of gossip.

There are three main theories about the origin of gossip in history:

The first theory is that Fuxi painted gossip in Hexagram Taishan, and it is said that there are also Fuxi painting hexagram platforms in Tianshui in Gansu and Henan.

Hexagram Tai Mountain, also known as Painting Hexagram Platform, is said to be the place where Fu Xi looks up at astronomy, looks down on geography, and begins to draw gossip, is located at the northwest end of Sanyang River, and is now under the jurisdiction of Weinan Town, Maiji District.

Of course, many modern scholars do not believe this, but believe that some inventions were entrusted to ancient celebrities.

In addition, in 1979, eight hexagrams were unearthed at the Qingdun site in Hai'an County, eastern Jiangsu, and historians believe that they belong to the late Neolithic period.

However, in the ancient environment of sparse population, many tribes, and poor communication tools, it took a long time for culture to spread to the far eastern part of Jiangsu.

The second theory is that Zhang Zhenghong's number of Zheng has evolved into gossip theory in multiple steps.

His article "A Trial Interpretation of Yi Hexagrams in Bronze Inscriptions in the Early Zhou Dynasty" studies a batch of digital hexagrams unearthed in the 20th century, and believes that there were a large number of digits (number hexagrams) first, and then simplified into several digits.

During the Warring States Period, these small numbers were simplified into binary odd-even symbols (represented by two numbers, one and six) (there were numbered gossip).

From the end of the Warring States period to the Qin and Han dynasties, it evolved into an abstract dualistic yin-yang symbol (only to have yin-yang gossip), and the yin-yang philosophy originated very late. This theory is very contradictory to some ancient texts, but because of this, it is also very influential.

The third is Liu Linying's astronomical hexagram that evolved into the gossip theory.

His "New Solution to the Mystery of the Origin of Yixue" expounded the theory of the hexagram system, arguing that the hexagram arose from the prediction activities of astronomers' Gui measurement tools.

The important evidence is that the hexagram system (such as the three yin and three yang) is the backbone theory of traditional Chinese medicine, not the eight trigrams can be explained, and the moon hexagram in the hexagram system has remnants in the "Guizang" and "I Ching".

His later treatise, "The Examination of the Six Elephant Zheng Methods for the Use of the Shang and Zhou Numerical Hexagrams", denied that the Yi Hexagram originated from the Zheng number theory, and argued that the Four Elephant Character Great Yan Zheng Method was thousands of years before the Eastern Zhou Dynasty was dominant.

Yi's divination is the use of the six elephant method, the complex number of the six elephants is only the number of the six elephants and their changes, etc., the six elephants of yin and yang are essentially six hexagrams, that is: the six trigrams and the eight trigrams have a long history of divination, and the origin of the abstract yin and yang concept is very ancient.

Conventional research has held that these three claims contain relatively strong arguments, and there are many other opinions.

Liu Jue put forward the theory of Guiying in 1946, believing that gossip originated from Tugui's record of the sun.

Feng Youlan believes that Bagua is derived from the imitation of the turtle omen of divination, which is a standardized "omen", and similar statements include Qu Wanli's Yi hexagram derived from the turtle divination theory.

Li Jingchi believes that the ancients used the knotted rope method to record the number of Zong, which later evolved into gossip, and the source of this theory is the ancient name of the ancient book.

Wang Ningsheng's gossip originated from the Yi Leifuzi. Huang Yilu believes that the Yi hexagram originated from the chicken culture of the Zhuang people, the descendants of the Xianyue people.

After thinking and studying for a long time, Lu Yuan didn't figure out how this gossip was different from Zhou Yi's gossip.

However, the harvest is not without gains, judging by the current situation, the history of this building will not be less than 5,000 years, plus his own experience.

From this, Lu Yuan concluded that the origin of the gossip was the first and more likely.

The latter statements about the origin of gossip are not right in time in the first place.

However, Lu Yuan doesn't plan to announce this, if he really announces this, it will ruin many people's jobs.

For a while, he couldn't figure out the origin of the gossip and Taiji diagram here, so Lu Yuan simply gave up research.

Stretching his body, Lu Yuan began to study the building itself carefully.

At this time, Lu Yuan discovered that the materials of this kind of building were completely man-made, and they were similar to modern concrete, but they were completely rolled concrete in all aspects.

After Lu Yuan took a small piece of building materials and handed it to the smart housekeeper, he continued to search the building.

As for the group of mermaids in the building, he forgot about it.

It didn't take long for Lu Yuan to find something nice on the building again.

This thing is two statues, but unfortunately both statues have been damaged.

It can only be vaguely seen that the statue is a human-headed snake body.

When he discovered these two statues, Lu Yuan's first thought was naturally "Fuxi" and "Nuwa"! These two great gods are legendary figures with human heads and snake bodies.

After discovering the statue, Lu Yuan searched again, but found nothing new.

At this point, he finally set his sights on the building.

"What is waiting for me here?" Lu Yuan's curiosity was aroused.

However, Lu Yuan did not enter the building immediately.

He would not forget that there was still a group of mermen in the building, and judging from the previous situation, this group of mermen obviously had intelligence.

This group of mermaids has lived here for I don't know how many years, maybe some powerful mechanism has been set up in it. Lu Yuan didn't want to die in such a daze.

After communicating with the intelligent housekeeper, Lu Yuan sent out all the idle bionic robots in one go.

A real robot army has appeared on Earth in this way, and if this scene is known to the public, it will definitely cause an uproar.

Under Lu Yuan's order, a full 67 heavily armed robot warriors were divided into eight teams and entered the building from eight directions.

Soon the sound of battle could be heard inside the building.

It took a full hour for the battle to subside.

When Lu Yuan stepped into the building, all the mermen had been completely subdued.

However, Lu Yuan's losses were equally heavy, and at this time there were only 28 of his robot warriors left.

Lu Yuan couldn't help frowning, although he had been prepared, such a huge loss made him feel a little distressed.

The materials obtained before have been basically exhausted, and until new materials are obtained, these robots will be broken and one will be missing.

Lu Yuan walked into the core of the building while feeling sorry for his loss.

At this time, he finally knew the reason for the heavy losses of the robot warriors......
