Kaiyuan Tongbao, as the name suggests, is a copper coin in the Kaiyuan period of the Tang Dynasty.

Due to the large number of itself, the price of a Kaiyuan Tongbao in the antique industry is not high, about 200 yuan.

But this one is different.

Jiang Xian bent down, stretched out his hand to pick up the copper coin, looked at the black rope tied to the copper coin, his eyes narrowed slightly, and the hand holding the black umbrella couldn't help but tighten.

"What's so strange about this copper coin Mr. Jiang?" Lu Tianyuan stepped forward and asked.

"Nothing...... It's just that the relics of the division were found. Jiang Xian exhaled, straightened up, and looked at the ground on the side, where there was a little trace of dried red blood.

"Kaiyuan Tongbao, a relic of the master's sect?" The credit knife man and Chen Shiyun and the others were all stunned.

"Don't be surprised, if it's a simple Kaiyuan Tongbao, it will naturally not become a relic of the master who covers the mountains and seas." Long Tiansheng's eyes narrowed slightly, looked at the copper coin and said, "But, if it's the Five Emperor Coins, or the Feng Shui Great Five Emperor Coins?" ”

The Five Great Five Emperors of Feng Shui?

Chen Shiyun and the credit knife man glanced at each other, and both of them looked abrupt.

The so-called Five Emperor Coins are five copper coins that represent the legendary Five Heavenly Emperors, and in the process of evolution, they gradually became the Great Five Emperors and the Little Martial Emperor.

Among them, the small five emperor coins are Shunzhi Tongbao, Kangxi Tongbao, Yongzheng Tongbao, Qianlong Tongbao and Jiaqing Tongbao of the Qing Dynasty.

The big five emperor coins are the Qin Dynasty's half two coins, the Han Dynasty's five baht coins, the Tang Dynasty's Kaiyuan Tongbao, the Song Dynasty's Song Yuan Tongbao and the Ming Dynasty's Yongle Tongbao.

One of the Great Five Emperor Coins has the highest value, if they are buried in the land of gold, wood, water, fire and earth for more than 50 years, and wear them together again, they are called the Great Five Emperors of Feng Shui, and they are the treasures of many Zhenzong sects on the rivers and lakes.

"Yes, this is the Kaiyuan Tongbao of the Five Emperors of Feng Shui." Jiang Xian exhaled slowly, and said to a few people: "And it is the special Five Emperor Coins in the mountains and seas that I collect, and the other Five Emperor Coins usually only use red ropes to wear them." ”

"But the Five Emperors Coin of the Mountains and Seas must be wrapped with a rope of the corresponding color to wrap part of the copper coin."

"Kaiyuan Tongbao should be in the water line of the five elements." Chen Shiyun thought thoughtfully: "Therefore, the water line belongs to the black, the Black Emperor of the North, so the black rope is used on it." ”

Jiang Xian nodded, and looked around the main hall: "Feng Shui Great Five Emperor Money, it is a set of feng shui magic tools that my master loves very much, if it is not for serious injuries and difficulties, I will not let them scatter ......"

"In other words......" Lin Ruoxue's eyes also saw the blood stains on the ground, and she turned her head to look at Jiang Xian: "The bones of the ancestor are likely to be inside?" ”

Jiang Xian nodded, took a deep breath, he entered the shadow cellar, in addition to the curiosity of exploring unknown historical legends, the more important thing was to collect the bones for the ancestor and the ancestor, and now this purpose seems to be close at hand.

He took a step and came to the wall carved with a mountain and sea, the familiar pattern, the familiar style, almost exactly the same as the one below the mosquito-free village.

"Is the ancestor here too?"

He looked around, the pillars carved with coiled dragons, the walls and mountains depicted on the walls, the walls in the hall seemed to show only the magnificent and vast scene of ancient times, and no longer reflected the sacredness of the giant.

"Let's go." Jiang Xian retracted his eyes, took a step, and walked from the bluestone avenue towards the hall behind him.

Behind him, Lu Tianyuan and everyone hurriedly followed, and walked towards it together.

The stone pavement was fairly smooth, with only a few signs of damage, and there were no corpses around, except for the occasional sporadic bloodstain.

Relative to the rest of the place clean abnormal.

Obviously, in the thousand-year-old history here, there has never been a rush and kill battle, just like a paradise in the netherworld.

Is it the deterrence of the five bridges of the serpents? A thought flashed in Jiang Xian's mind, and he continued to walk along the scattered bloodstains. It didn't take long for Lin Ruoxue's expression to move: "There is a voice...... It's still the sound of the water, which is much more intense than the river outside. ”

Jiang Xian's heart was excited, there was a water master ancestor who was very likely to be there. His steps couldn't help but be two points faster, and before he walked out of the hundred-meter meter, his expression changed slightly, and he turned his head to everyone: "Do you feel that there is anything wrong?" ”

"Isn't that right?" The credit knife man and Chen Shiyun were stunned for a moment, and looked around carefully, with doubts on their faces.

Lu Tianyuan, Gu Mingrui, Yamamoto and others next to them all observed carefully, but they didn't find anything for a while.

"Mr. Jiang......" Xue Rong suddenly spoke, his eyes changed slightly: "Isn't it, the temperature here is higher than outside?" ”

"No, there's also getting humid ......"

Getting hotter and hotter and getting humidity?

Everyone was stunned, and after Xue Rong's reminder, they carefully recalled the feeling just now, and it seemed that there was really a feeling of temperature increase and humidity increase.

"Wind speed, temperature and humidity will have a great impact on sniping, especially since there are no scopes calibrated for humidity, so we have been specially trained to sense humidity and temperature." Xue Rong turned his head to look left and right, and his gaze fell on Jiang Xian: "I can be sure that the temperature and humidity here are higher than the hall just now." ”

"The temperature in the ground is rising...... This shouldn't be! Chen Shiyun touched his chin, with a bit of thought in his eyes; Could it be that there is an underground magma connected to it, and there is a pool next to it? ”

"Whatever it is, let's go see it first."

Jiang Xian looked ahead, took a step, and continued to move along the road.

After noticing the changes in temperature and humidity, they clearly perceived the feeling of temperature increase as they walked forward.

The surrounding air became more and more humid, and gradually, water droplets condensed on the surrounding walls, slowly sliding downward, and the beams and ceilings at the top of the palace dripped, dripping a few drops from time to time, making a crisp sound.

Syllable.

Jiang Xian's footsteps stopped, and the blood stains pointed to the gate in front of him.

He also clearly felt that the previous feeling of humidity and the feeling of rising temperature came from inside the door.

The big black umbrella was raised, and he lightly touched the door, his arm slammed into force, and the heavy stone door did not move at all, and the surrounding environment was still the same.

Taking a deep breath, he held the paratrooper in both hands, the pointed head in front of him was against the door, he took a deep breath, the muscles of his whole body were extremely relaxed in an instant, and then in the next moment, all the soothing muscles tensed violently, and the green tendons on his arms bulged up instantly, and a surging force suddenly acted on the front!

"Open!!"

Jiang Xian let out a low shout, and the door in front of him suddenly trembled, and the next moment it shook slightly towards the back, and a faint white mist floated out of the gap.

Seeing this scene, Jiang Xian's heart suddenly tightened, and a sense of danger suddenly rose from his heart.

In an instant, his body moved to the side, and the black long straight who rushed forward also retracted backwards, reached out and grabbed Lin Ruoxue, dragged him into his arms, and said in a low voice:

"Get out of the way!"

The moment the words fell, the door that had opened a small crack slammed open, and a violent storm swept away the white air current.

The closed black long straight opened in an instant, stopping in front of Jiang Xian and Lin Ruoxue. The violent storm made the umbrella surface tremble constantly, and the alloy umbrella bone kept shaking, and Jiang Xian, who had just burst out of strength, almost couldn't hold the umbrella for a moment.

Lu Tianyuan and the others in the back quickly dodged to both sides the moment Jiang Xian shouted, and Chen Shiyun hid directly behind Jiang Xian and the others.

But the umbrella surface could not completely envelop them, the storm with white air currents instantly invaded the surroundings, and a hot and humid feeling instantly invaded, and before they could lie on the ground, several people hiding by the wall were even blown back six or seven steps!

The wind passed through and stopped in an instant.

A few people who were dodging on the side had messy hair, and a few people who did not have a gas area were red, they were afraid that the air would be poisonous, and everyone held their breath when the wind blew just now.

"Seems to be just ordinary water vapor ......"

Jiang Xian stood up, put away the open black long straight, and shone the flashlight towards the open door in front of him.

The white mist was so thick that even a penetrating military flashlight could not penetrate it. However, as the fog continues to drift outward, the visibility inside the door is slowly improving.

He stood there, not in a hurry to enter, just waiting quietly.

After a while, the heat was still surging outward, but the space behind the door was already faintly visible.

Jiang Xian didn't say a word, he immediately walked in, and the flashlight shone at the same time around, and in just a moment, his pupils suddenly contracted,

Lin Ruoxue and the others, who came in closely, also saw everything behind the door at the same time, and there was consternation in their eyes at the same time.

As far as they could see, in the range of the flashlight's beam, a large area of golden light reflected into their pupils. In the corners of the walls, on the slate floors, around the steaming pools, large swaths of gold and copper coins and jewels were scattered here.

In addition to these gold and silver treasures, the walls are inlaid with fluorescent orbs, which together form a pattern of stars.

"Is this the treasure room?"

Xue Rong looked at these precious belongings and couldn't help but wonder, "But, who would put the treasure on the edge of the pool?" ”

"This was certainly not a place to hide treasure in the first place." Jiang Xian stepped forward and looked at the pool. The water in the pool is not clear in color, it is a little yellowish, and a meter directly above the pool, there is a stone pillar hanging down from above.

Jiang Xian stretched out his hand and knocked on it, the stone pillar made a crisp sound, and the people on the side were stunned: "This voice...... Empty? ”

They hurriedly walked over, bent down, and looked down from the top of the pool, only to see that the stone pillar was hollowed out in the center except for a solid stone body on the periphery, and in the inner test of the stone body, there was a layer of metal alloy tinged with yellow.

"It's ...... Artificial plumbing? ”

Chen Shiyun was extremely stunned, he looked at this pipeline, and then looked at the rock formation above: "What did Rong Wu do with this in the first place?" Where is this pipeline going to be connected? ”

"Where?" Jiang Xian bent down and picked up a gold coin from the edge of the pool, his eyes narrowed slightly, and he looked at Chen Shiyun: "Perhaps, this is the cornucopia that leads directly to Longhu Mountain." ”
