The underground river leads to the east, and on the right side of the river is a spacious beach with large and small pebbles, which have been heavily pressed before, and are very strong and do not fall into the ground.

The river was wide enough to sweep, and the three of them began to speed up, and after a few moments, zigzag stone stairs leading to the top of the cave appeared on the stone wall on the right, but these stone stairs had been chiseled and ordinary people could no longer walk up.

Zuo climbed the peak and looked up, and found that there was a green area near the right side of the top of the stone wall, and there was little moss in the cave.

"This should be the entrance to the mausoleum of King Ba Ji." Zuo Dengfeng raised his hand and pointed his finger.

Hearing this, Yufu nodded, raised his hand and grabbed a pebble and threw it at the copper door, the sound of the pebble hitting the copper door was not very serious, which showed that the copper door was not very thick.

"What's wrong?" Yufu saw Zuo Dengfeng's brows furrowed, and he was slightly puzzled.

"The poison derived from each earth branch has the habit of feeding the earth branch, and if the earth branch was trapped in the mausoleum, the previous poisonous python similar to a centipede would have already crashed through the bronze door." Zuo Dengfeng shook his head and said.

"You mean to say that the earth branch is not in the mausoleum." Jade asked with a little hair.

"It's hard to say." Zuo Dengfeng took out the map and carefully compared, judging by the route and distance traveled by the three people, this is directly below the presidential palace, that is, where the mausoleum of Bawang Ji Hao is located.

"Amitabha, let's go up and explore the way first." Iron Shoes retracted his gaze and spoke.

"Don't rush for a while, continue east." Zuo Dengfeng shook his head and spoke, and then stepped forward.

"Why east." Iron Shoes followed in amazement.

"The poison is too big to enter the cave to hunt the snake, but it always has to eat, but we haven't found out where its food is until now." Zuo Dengfeng shook his head and said.

Hearing this, Tie Shoe stopped asking questions, and followed Zuo Cui and the others to the east.

After a few miles, there was a huge underground lake in front of me, the surface of the lake was dozens of acres, and there were a large number of gray-white salamanders and swimming fish and turtles in the lake, these giant salamanders were much larger than ordinary salamanders, and their movements were slow, and the fish and turtles did not swim fast, and the poisonous snake before could feed on them.

At this point, the underground channel narrows and continues to flow eastward from under the rock wall on the east side.

"All the craftsmen who built the mausoleum were killed here." Zuo Dengfeng stretched out his hand and pointed to the large number of bones remaining by the lake, although the bones were old and decayed, they could still be identified as human bones through the round skull.

"Let's go to the grave." Yu Fu said that she knew that the reason why Zuo Dengfeng wanted to find the food source of the poison was that she hoped to find the Yin Earth Ox, but there was no trace of the Earth Cow in front of her, and now there was only one way to enter the tomb.

"A lot of people were slaughtered here, can you summon their spirits and ask about the situation." Zuo Dengfeng turned his head to look at the jade whisk.

"It's been too long." Jade Fu shook her head and said.

"Let's go." Zuo Dengfeng let out a long sigh and turned his head back.

The group of three people returned the same way, and returned to the bottom of the stone wall where the bronze gate was located.

Zuo Dengfeng did not hesitate, swept directly onto the stone wall, and shook down the copper door with his palm, the copper door was an inch thick, to be exact, it was not the copper door, because it did not have a door shaft on the left and right, just a huge copper plate used to seal the gap.

After the copper plate fell, Zuo Dengfeng flashed to the west side, this mausoleum has been closed for a long time, the air inside must be extremely dirty, although there is no wind in the cave, but the underground river can bring the turbidity in the mausoleum to the east.

After a while, the three of them walked up the stone steps inside the bronze door, the stone steps were very spacious, and the three of them could walk on it in parallel, going up dozens of feet, and a stone slab appeared above.

Zuo Dengfeng probe knocked on the slate, and found that the slate was not too thick, emitting an aura to support it slightly, and he felt that there was no negative pressure on the top.

After a short period of silence, Zuo Dengfeng raised his eyebrows and shattered the stone slab, and then jumped up.

In front of you is a spacious burial chamber, covering an area of about five acres, the main burial chamber and the burial area are not separated, the tomb is in the middle of two rows of tomb stone beasts, seven on the left and right, the center of the tomb beast is a two-zhang wide and narrow road, the left side of the road is some burial utensils, the right side of the road is dozens of sarcophagi, there is a square stone platform at the end of the road, a bronze coffin is parked on it, the whole tomb does not feel how luxurious, but it seems a little shabby, because the seven copper tripods have shown that the owner of the tomb is the identity of the princes, As a prince, the specifications of such tombs are not high, and the burial utensils are not rich.

"Not here." Zuo Dengfeng looked around and shook his head slowly, Thirteen had expressed the size of the Yin Earth Ox, which was the same size as an ordinary buffalo, and the things in the tomb were clear at a glance, and there was no earth branch at all.

"Could it be that the Inner Dan of the Earth Branch is here?" Jade Whisk turned her head and spoke.

"There is this possibility, look for it, the inner dan of the earth branch is the size of a soybean, and the inner dan of the soil should be gray." Zuo Dengfeng walked along the road to the copper coffin on the stone platform in the north, to be exact, the copper coffin should not be called the copper coffin, the outer coffin set on the outside of the coffin should be called the coffin, and the body stored inside is called the coffin.

"Master, come up and help." Jade Whisk lowered her head and said to the iron shoes below.

"Amitabha, the old man is guarding you below, boss, you go up and help him find it." Iron Shoes did not want to go to the grave.

"No, don't, don't come up to you both." Hearing this, Zuo Dengfeng hurriedly turned his head and said, he knows very well what kind of virtue the boss is, and if he finds the earth cow, Neidan will definitely swallow it privately.

After Zuo Dengfeng finished speaking, he turned around and continued to go north, there are few organs in the mausoleum of the Zhou Dynasty, in addition, the organs in the mausoleum are generally set in a relatively small space, there is a lot of space here, there is no condition to set up an organ at all, the most important thing is that it is at least a few miles away from the ground, as long as the passage above is sealed, almost no one can enter the mausoleum, so the owner of the tomb has no need to set up an organ.

The stone platform where the coffin is placed is three feet from the ground, one layer per foot, so that this copper coffin is the highest in the entire burial chamber, Zuo Dengfeng quickly lifted the coffin lid, inside is a dark yellow wooden coffin, between the wooden coffin and the copper coffin placed some gold and jade and other objects, these utensils Zuo Dengfeng didn't even look at it, and directly extended the aura to move the wooden coffin out of its entirety.

Although the wooden coffin seemed to be complete, it was after all three thousand years old, and after being removed from the bronze coffin, it immediately fell apart, and the bones inside were revealed.

The bedding and covering in the coffin had already turned black, and the clothes worn by the corpse had also rotted, and only the skeleton of the corpse remained.

Zuo Dengfeng didn't come to archaeology, nor did he come to rob tombs, so he didn't look at the golden crown on the head of the corpse and the peiyu around the bones, what he was looking for was a gray round thing.

Just when Zuo Dengfeng turned the bones of the corpse with his aura, Yu Fu came over to help inspect it, and since Neidan was very small, all tubular artifacts had to be checked.

"It's about to be thrown away." Zuo Dengfeng glanced at it and found that Yu Fu was holding a black wooden pipe looking up and down, the wooden pipe was one ring thick, one end was closed, and the inside was hollow.

"Tie Limu's, there may be something hidden." Jade Whisk looked sideways at the woodpipes.

"It's a wooden tray, it's about to be thrown away." Zuo Dengfeng frowned and said.

"What is a wooden pallet." Jade Whisk turned the wooden pipe upside down, checking to see if there was anything hidden inside.

"You should know the silver tray used by Ximenqing, it's similar to that." Zuo Dengfeng reluctantly spoke.

As soon as these words came out, Yufu was stunned for a moment, and after reacting, she quickly threw away the woodpipe, in fact, she didn't know what the silver tray that Zuo Dengfeng was talking about, but she knew who Ximenqing was.

"I haven't seen it." After throwing away the woodpipe, Yufu's face flushed with shame.

"I haven't seen it either, but I can guess." Zuo Dengfeng said casually.

Yufu was naturally embarrassed to say anything more, and hurriedly left here and walked towards the sarcophagus on the right.

Zuo Dengfeng continued to rummage, and finally determined that the Neidan of the Yin Earth Ox was not in Ji Xuan's coffin, and then walked to the left side, where the funeral instruments and living utensils were stored, and some pottery urns and clay pots still kept blackened plant seeds, these things Zuo Dengfeng did not move, because it was impossible to hide Neidan in it, and there was no need to carry out a destruction inspection, so leave it to future historians and archaeologists to study.

Ba is originally a poor place, the princes and kings of a poor place do not have many good things, but this foreign household is not a good thing, gold and silver are not greedy for wine, there are a lot of wine jars and copper wine vessels on the left side, one of the small wine jars has half a jar of wine, Zuo Dengfeng patted open the mud seal and smelled it, the wine is green, and the fragrance is fragrant.

"Master, follow me, and you will live in vain." Zuo Dengfeng walked to the gap and gave the small wine jar to the iron shoes, there was very little wine left in the wine jar, and Zuo Dengfeng was reluctant to drink it himself.

"Amitabha, that's true." Iron Shoes happily took over the wine jar, as long as it is a person, there is something to like.

Zuo Dengfeng immediately walked to the right, Yufu had already opened five or six sarcophagi at this moment, these sarcophagi were all women's bones, no need to ask if they were all women who were buried for Ji Xuan.

"Nedan doesn't seem to be here." Jade Fu shook her head and said.

"But the poison derived from the earthly branch is here, and the poison is here, indicating that the earthly branch or the inner dan of the earthly branch is not far from here." Zuo Dengfeng frowned and spoke.

"Thirteen has a keen sense of smell, so you can let it find it." Jade Whisk stretched out his hand and pointed at Thirteen, who was wandering around the tomb.

"Thirteen, the Nedan of the cow you fought with is nearby, find out." Zuo Dengfeng beckoned and shouted over thirteen.

"Meow~" What Zuo Dengfeng didn't expect was that Thirteen shook his head again and again when he heard the words.

"What does thirteen mean?" Jade Fu asked suspiciously.

"It means that the earth cow is not here, it is impossible, the poison derived from the earth cow is here." Zuo Dengfeng frowned and said, Thirteen will definitely not shake his head to disobey, it can only shake his head because the earth cow is not here.

"That strange snake in the shape of a centipede may not be a poison derived from a native ox." Yufu pondered for a long time and shook his head and said.

"Why do you say that?" Zuo Dengfeng frowned and asked.

"Do you remember what happened in the ancient city of Puguo?" Yufu reminded him.

Zuo Dengfeng heard the words and immediately recalled that he had been to the three rivers in the parallel area of the country and the country of Pu last winter, the boss is the water branch of the country of Ji, and the branch of the country of Pu is a water pig, the residents of the ancient city of Pu country are all poisoned by the poison derived from the water pig, the root cause is that Jiang Ziya wants to borrow the branch of the country of Pu to fight against the thirteen, but was rejected by the country of Pu, Jiang Ziya began to use the poison derived from the strong and water pig in a hurry to resist, and was killed by a metal bird and poisoned the residents of the country, In other words, the poison of the Yin earth ox should be a bird, not a centipede.

In addition, when Jiang Ziya fought against the thirteenth, Ji Qian had already run to Ba with the Yin Native Ox, and since Jiang Ziya was riding a bird derived from the Native Ox, it meant that he came here later and borrowed the Yin Native Ox from Ji Chen.

"Could it be that the perennial dwelling underground wings have degenerated?" Zuo Dengfeng felt that Jiang Ziya would not be able to borrow it and not pay it back.

"To tell you the truth, from the beginning I suspected that the poison was not derived from the earthly branch, but it itself was surnamed Jin, so I am not sure if it is another legendary serpentine monster." Jade Fu shook her head and said.

"What a monster." Zuo Dengfeng asked.

"Hooked Snake."
