I was stunned to hear that the Dragon Travelling Cave was a famous tourist attraction in Longyou County, known as the "Ninth Miracle of the world". It was a series of huge underground caves, and was also the largest man-made underground building in the world that was discovered so far. I had once visited the Dragon Travelling Stone Cave. Those magnificent underground caves were indeed very similar to the space in front of me. There were also large stone steps like these. There were even pools of rocks at the bottom that were similar to the one here!

"Leader, what are you talking about? Shouldn't Dragon Travelling Stone Cave be a Dragon Travelling Stone? "Why did you come here?" Before I could ask further, San Mao asked first.

The Taoist pointed at the map and said, "We were walking around in the mountains and were actually not far from Dragon Travelling County. After running for half a day, we'll be even closer to it!"

The Taoist put down his phone and continued, "On the surface, there are only five Dragon Travelling Stone Caves, that is, the ones that are open to the public in the scenic area, as well as 25 caves that have not been opened to the public, and I have joined an amateur research organization on grottoes. According to their estimates, there should be no less than 70 grottoes in this area.

"Dragon Travelling Stone Cave?" Not far from here. Didn't they say that the Dragon Travelling Cave was created by aliens? Why is there a coffin here? " Mao Tou scratched the back of his head in puzzlement, and then cried out while pointing at the coffin: "Ah! Was this an alien's tomb? Was it an alien buried here? No wonder, the engravings on it aren't like us at all, our feelings aren't human at all! There shouldn't be an alien dumpling inside, right? "

"No …" "It's not …" The Daoist laughed bitterly and waved his hand: "If I'm not wrong, this should be the King Xu Yan's tomb!"

"King Xu Yan?" None of the three of us had ever heard of it before, so we asked the same question at the same time.

"Yes!" The Daoist returned the mobile phone to Mao Tou, then walked over to the coffin and pointed at the strange dog-faced man. "King Xu Yan is the monarch of the Xu Nation during the Western Zhou Dynasty, he is a very mysterious person."

Sure enough! I thought to myself that I had guessed right. This coffin really belonged to the Shang and Zhou Dynasties.

The Taoist laughed and said, "This King Xu Yan, according to the legends, when he was born, his father thought that this was an ominous thing and threw him into the water. However, his guard dog, somehow managed to get him back from the water and bit off his outer skin, revealing a boy inside!"

This dog's name is Swan Cang, and later became the guardian god of King Xu Yan, as well as the totem of King Xu Yan's family. It is said that it was transformed from a dragon, and when it was about to die, it grew horns on its head, and on its butt grew nine tails.

The Taoist touched the doggy face on the coffin and continued, "Throughout Chinese history, other than the King Xu Yan, there are no other famous families or families who worship dogs. This should be his tomb!"

Hearing this, my heart jumped, and I asked the Taoist: "But you just said that this King Xu Yan is the king of the Ancient Xu Country, if I remember correctly, this Ancient Xu Country should be in Xuzhou with cash. It should be around the border between Shandong and Jiangsu, why is his tomb here?"

"You're right." The Daoist nodded his head in approval and said, "The Ancient Xuguo Country is indeed near Xuzhou. During the Western Zhou Dynasty, the political and economic center was always in the Yellow River Basin. Today, in Shaanxi Province, the Kingdom of Xu is considered to be a remote place, and according to what we heard at that time, it belongs to the 'eastern barbarians'."

"The XuRong Tribe that the King Xu Yan belongs to is the alliance master of the eastern barbarians. Originally, their country's power was relatively strong, but after the death of King Xu Yan's father, he succeeded as the king. In the historical records, 'five hundred miles in each direction, thirty percent of the six nations' all paid tribute to him. This naturally caused the Zhou Dynasty to be on guard, and with the addition of the coveting of the spell that can turn a stone into gold, in the end, they were found to have committed a crime and sent out troops to suppress him. "

"Although the Kingdom of Xu is powerful, it is obviously unable to contend against the Zhou Dynasty, which was at its peak during the autumn of that year. They immediately turned into an army and destroyed the entire country, and the King Xu Yan also abandoned the country to flee." Although the Kingdom of Xu is extremely powerful, but of course they are unable to contend against the Zhou Dynasty, which was at its peak during the autumn of that year.

After saying that, the Taoist paused for a moment, then shook his head with a smile. Initially, out of all the conjectures in the Dragon Travelling Stone Cave, I felt that conjectures about the King Xu Yan s were the most impossible. I don't even believe that it could be founded by aliens.

"But …" I looked around me and this incomparably large underground space, and asked with some doubt: "Logically speaking, King Xu Yan is the ruler of a dead nation, how could he still have that kind of power to construct this kind of underground structure? Such a large project, according to the level of productivity at that time, would probably be an impossible mission, wouldn't it? If the entire Zhou Dynasty were to be built using the power of an entire nation, there would still be a possibility for him, the Herd King who is in exile, to have built such a project with human and financial resources. "

"That is another mysterious legend." The Daoist laughed mysteriously and said: "It is said that the King Xu Yan was born with three eyes, and on its forehead is a single vertical eye, unable to see through things. However, it has the function of turning stones into gold, and according to the historical records, 'its state is completely gone, and thus the King has gained his name!"

He took out his own cup of water and took a sip, then said: "Legend has it that the King Xu Yan has some extraordinary methods and knows evil arts, thus he has another nickname, Demon King!"

"Haha …" San Mao who was at the side scoffed and mocked: "Three eyes? Then wouldn't it be Erlang Shen, Yang Jian, if I bring a dog? "

The Taoist didn't think much of it and instead nodded his head and said, "The legends of the ancient Divine Seal Decree regarding Yang Jian are now being analyzed by many scholars from the King Xu Yan … Uh, there's also Nezha, he also came from him! "

This Nezha was born a meatball, too, and was regarded by my father as an ominous thing.

At this time, Mao Tou could no longer hold back and asked: "Master, you have said so much, when are we going to open the coffin?"

Forget about Mao Tou, this King Xu Yan is being so mysterious. Even I can't stand it, I want to immediately open the coffin and see if he has three eyes.

At that moment, I suddenly felt the light in front of my eyes go off. I thought someone had run out of batteries, and I was about to remind everyone to turn on only one flashlight at a time to save electricity. Lowering my head, I saw Mao Tou turn his head to look in a direction in a daze. I followed his line of sight and saw that out of the candles at the four corners of the coffin, there was one that had been extinguished, emitting white smoke in spirals!
