The ancestral land of the eel tribe is quite close to Bai Ze, and basically there is only a distance of more than two hundred steps between the two, which can be said to be very close, and because it is too close to the water source, the soil of this tribe's ancestral land is particularly wet and muddy, and it is full of mud without stepping on it for a few steps, which is particularly viscous.

Aside from the cone huts and the bone altar, the eel tribe didn't seem to have much value on the surface.

"Go and tear down all the huts and see if there's anything in them that we can take with us. Shen Nong said to the ordinary Huangqiu people who had not been blessed by their own brute force.

Under Shen Nong's order, these clansmen immediately ran over and smashed all those wooden houses with the weapons in their hands, these wooden houses were only made of wood and dry grass, and there was no quality to speak of, so it was very simple to smash them.

Watching his people go about their work, Shen Nong wandered around the ancestral land of the eel tribe with nothing to do, first of all, he was most interested in the bone altar, only to see that this altar has three steps, the height is about more than three meters, Shen Nong needs to look up to see the top of the altar.

Out of curiosity, Shen Nong stepped on the steps and walked up, this round altar was all piled up with various bone rods, bone fragments, and bone fragments, and even built an exceptionally strong and stable shape for the people of the Mud Eel Tribe, Shen Nong couldn't help but secretly admire in his heart, although there was no too advanced civilization in this era, but the existence of some things still surprised Shen Nongde.

Walking to the top of the round altar, the stone pillar with the skull immediately attracted Shen Nong's attention, when he stood at the bottom of the round altar before, he couldn't see this stone pillar with his height.

The ground near the stone pillar is full of dense blood grooves with complex lines, and these blood grooves are like thousands of rivers returning to the sea, and they are finally connected to the bottom of the stone pillar, and it can be seen that the blood in these blood grooves will enter the stone pillar after a flow.

At this time, Shen Nong's eyes were all on the body of the skull, and what Kadokawa and the others had told him before was that the goal of the Mud Eel Tribe's sacrifice was to sacrifice the ancestral fire, but Shen Nong came over this time, but he didn't see any trace of the ancestral fire, and the only conspicuous thing on this circular altar was this skull.

"Something is wrong. Shen Nong stared at the skull and couldn't help but think in his heart.

He could clearly feel a strong Qi from this skull, this Qi was very strong, Shen Nong had absorbed that stone knife 'Wutongtai' for a long time, but he had never accumulated so much Qi like this skull, and the other party's Qi could be called surging and majestic.

"Good stuff. Shen Nong couldn't help but say, if he didn't guess wrong, this skull should also be something similar to 'Tongtai', which has the effect of automatically accumulating Qi.

Thinking of this, Shen Nong directly stretched out his hand, intending to pick up the skull in front of him, but at this time, the 'Wutongtai' stone knife that had been pinned to Shen Nong's waist suddenly trembled violently, and the shaking amplitude was very exaggerated, Shen Nong immediately stopped his movements, and then retracted his hand.

When he was learning witchcraft from Luo Man before, Shen Nong remembered that Luo Man once told him a thing, in addition to the ability to absorb and accumulate Qi, this kind of thing can occasionally drive away disasters and avoid disasters, and remind the witch who wears it is in danger, but this kind of thing is very occasional, and the better the quality of Tongtai, the greater the chance, and the chance of low-quality Tongtai is very slim.

This will make Shen Nong's Wutongtai suddenly tremble, according to what Luo Man said before, this phenomenon is a precursor to impending danger.

However, Shen Nong was standing on the altar now, there were no enemies or beasts around, where would the danger be?

Shen Nong's eyes couldn't help but stare at the skull vigilantly, he bent down to pick up a broken leg bone from under his feet, and then gently tapped it on the skull.

Rumble!!!

The moment the leg bone touched the skull, a cyan flame ignited directly from the skull's eye sockets, and after a few breaths, the entire skull was wrapped in cyan flames, turning into a skull bathed in flames.

The flames of the green flame surged more than two meters high, occupying the entire stone pillar in an instant, looking at the fire amazingly hot.

Shen Nong just stood next to Qing Yan, and he felt that the skin of his whole body became burning at this moment, and the hairs on the surface of his skin directly began to scorch, emitting a strange smell. 、

And the most terrifying thing is the leg bone that Shen Nong is holding in his hand, the moment he just touches it, this leg bone is burned into juice by the green flame, and this burning speed can be described by the word 'melting'.

Pretty scary!

Shen Nong immediately couldn't help but leave a cold sweat on his forehead, and he was afraid for a while, fortunately, Wutongtai rarely reminded himself, otherwise Shen Nong would have at least one arm to explain here today.

Qing Yan appeared quickly and disappeared quickly, and after more than ten breaths, he retracted back into the skull and disappeared in an instant, if it weren't for the scorching breath left in the air and the half-melted leg bones in his hands, Shen Nong might have felt that he had hallucinated in front of his eyes just now.

"Could this be the ancestral fire of the Mud Eel Tribe? But it's too weird, it's not the same as the ancestral fire I imagined. Shen Nong threw away the leg bone and immediately stayed away from the skull.

Compared with the ancestral fire of the Mud Eel Tribe, the ancestral fire of the Huangqiu tribe is much more normal, although Shen Nong still doesn't know how those flying buds appeared from the Huangqiu Ancestral Fire when the fire broke out in the big cave.

Glancing at the skull with some fear, Shen Nong knew that this thing was not strong enough to take it away with his current self, and the mysterious green flame alone was no longer something that Shen Nong could handle.

"Let's just put it here for now, and when I get back, I'll have a chance to ask Luo Man, and he might know what to do with this thing." Shen Nong said, then turned around and walked down the altar.

This bone altar should have been specially built by the Mud Eel Tribesmen for sacrifice, and there were no other precious items except the skull, so Shen Nong walked towards the Huangqiu Tribesmen who were searching for the resources of the Mud Eel Tribe on the side of the ruins of the cone wooden house.

Seeing Shen Nong coming, the pecking bone suddenly ran in front of him, and asked excitedly, "Wu, guess what we found?!"
