This is a box made of bronze. After being burned by the fire, the outer layer turned black.

Chen Yulou washed it with water, and the lines on the surface of the copper box were revealed.

Carved on it are scenes of Dian people making sacrifices. Based on this calculation, this copper box is also from two thousand years ago.

However, the strange thing is that the copper box was swallowed by a big insect. Logically speaking, it has been corroded by gastric juice, so it cannot be preserved in such a good condition.

Partridge Whistle guessed that the outside of the copper box might have been coated with white wax, but it was burned away by the fire.

The copper box is a square object with no gaps on the outside. It should be locked with an internal mechanism and needs to be opened using a specific method.

Ye Bai lifted up the copper box weighing several dozen kilograms and shook it, and there was a sound of some hard object hitting it inside.

At this time, Chen Yulou accidentally discovered that there were two small holes on the bottom of the copper box. The holes were blocked by black ash and were not easy to find.

"This should be the keyhole, but the shape of these two holes is strange and irregular, but I seem to have seen it somewhere." Chen Yulou held his chin in deep thought.

After being reminded by Chen Yulou, Ye Bai also found that these two holes were very familiar.

A flash of cleverness occurred, and Ye Bai suddenly thought of the short staff with a dragon head and a tiger head found in the jade coffin. The size and shape of them seemed to be very close.

Ye Bai divided the short stick into two parts, inserted them into the keyholes and turned them. Hearing the sound of the internal lock springing, the copper box was slowly opened.

However, Chen Yulou was disappointed with what was inside. There was only a piece of jet black crystal.

The black crystal is as big as a fist, and I don’t know what it is used for.

In Ye Bai's opinion, if it can be sealed so tightly in a copper box, this dark crystal must have a special effect on King Xian.

Chen Yulou put the crystal in his hands and weighed it. Oops, it's quite heavy. No wonder the hollow bronze box is so heavy. It turns out that one-third of the weight is the crystal.

"Third brother, please keep the crystal first. We'd better gather the troops as soon as possible." Partridge Whistle said, no matter how good the treasure is, as long as it has nothing to do with Muchen Bead, he doesn't care.

Ye Bai was about to put the crystal into the space when he saw Xiao Hei coming over with a flattering look on his face.

It groaned softly, indicating that this thing was good for it.

Ye Bai became interested. It would be useful to Xiao Hei. Could it be that the black crystal contains some special substance?

Ye Bai asked carefully, but unfortunately Xiao Hei couldn't explain it. He just instinctively wanted to swallow this crystal, which was the desire from his blood.

"I'll have people study it after I get back. If it's really good for you, I'll give it to you."

Ye Bai made a promise, Xiao Hei called out lightly, and followed Ye Bai's instructions to go back to find the waterway.

If they can find an underground water vein leading deeper into the Worm Valley, Xiao Hei will be waiting for them in front. If they can't find it, the Snake River at the entrance will be waiting for their return.

Seeing Xiao Hei's back disappearing into the pool, Ye Bai smiled. Xiao Hei had worked hard all the way, so he had to give him some sweet treats. Otherwise, according to Xiao Hei's temperament, he would work hard and fish at the critical moment.

After exiting the cave, there are valleys and valleys outside, with misty clouds.

Walking on the artificial stone stairs, Ye Bai compared the map in the system to determine the location of the king's coffin.

There are many human leg bones scattered on the stone stairs. They were probably left behind after the death of the slaves who built the plank road. Ye Bai was not surprised to see many traces of King Xian's brutality along the way.

After walking for a while, the stone stairs on the plank road turned into rotten wooden paths, making it impossible to pass.

However, long iron nails had been drilled into the cliff by the troops who had taken the lead. With the help of these iron nails, the few people were able to travel unimpeded.

Looking at the spiral plank road surrounded by clouds and mist, Ye Bai shook his head slightly.

Most of the remains of the plank road are built with wooden piles and stone slabs, and they hang on dangerous cliffs. Two thousand years ago, this was definitely a lot of work.

At this time, Ye Bai heard Qi Tiezui's cry: "Third Master, we are here!"

Qi Tiezui was seen standing on the empty cliff bank below, waving his hands at them. The two people standing next to him were Huo Xiangu and Qi Xiaohei.

"This kid." Chen Yulou couldn't help shaking his head and smiling.

After arriving at the cliff, Ye Bai found that the space was quite large, enough to accommodate dozens of them to rest.

"Third Master, are you not injured if you stay in the cave?" Qi Tiezui took the compass and hurriedly stepped forward to express concern.

"You're worried that I'll get hurt, why don't you stay with me?" Ye Bai joked.

Qi Tiezui stared at him and said: "Third Master, I just followed your order to withdraw. Besides, my small body will only hinder you if I stay. If I really get trapped in the cave, my father will still look for you."

trouble."

Qi Tiezui had a good reason. Ye Bai smiled and was too lazy to argue with him. He asked again: "I have taken out all the food for eating. How is it? What did you find?"

"Third Master, I really discovered something."

Qi Tiezui pointed to the distance and saw a dense forest, with the faint outline of a palace on the top of the mountain opposite.

Unfortunately, the clouds and fog obscured the view, and the palace was looming, making it unreal.

"That must be the Minglou Pavilion built by King Xian, and the coffin of King Xian should be there."

Ye Bai shook his head slightly. On the system map, there was indeed a palace on the mountain in the distance, but the coffin of King Xian was not in the palace, but under the water.

"After looking at it for a long time, you came to this conclusion?"

Qi Tiezui was a little unconvinced. Just when he was about to open his mouth to defend himself, he heard Chen Yulou say in a solemn voice: "There is a situation!"

A group of large birds flew out of the dense forest below the cliff bank. These large birds had antlers on their heads and turned out to be a group of Gu eagles.

It seems that what Ye Bai caught before was a lone Gu Eagle.

The Gu Eagle's cry was breathtaking. Everyone had suffered a loss and covered their ears. Even so, the unpleasant cry still made everyone dizzy.

At this time, the bone sculptures tied into rice dumplings heard the cries of their companions and kept whining, as if trying to attract their attention.

Qi Xiaohei frowned and shot out the stone in his hand, knocking the Gu carving unconscious instantly.

The Gu eagles gathered together in the air, attacking with sound waves one after another.

"What are these Gu carvings so crazy about and they won't stop?" Qi Tiezui couldn't help but complain.

"Someone in the dense forest must have disturbed them." Partridge Whistle took out his gun case, and with two gunshots, he saw two Gu Eagles falling from the air.

The group of Gu eagles were frightened by the gunshots and the death of their companions. They fled in all directions and flew out of the valley.

Without the unpleasant sound, everyone breathed a sigh of relief.

Huo Xiangu suddenly said: "Why do I think this forest is a bit strange? I seem to have never seen the plants below."

Ye Bai looked around and saw that this dense forest was indeed unusual. The old trees were thick and tall with thick roots, and many of the vegetation were even unrecognizable to Ye Bai.

"There's something weird down there, do you want me to go explore it first?" Qi Xiaohei asked.

"Don't worry, someone seems to be coming."
