In the center of the altar was a huge dead tree, the trunk of the dead tree was ten kilometers thick, and on the trunk, six thick chains of different colors wrapped a huge golden skull shelf with a height of nearly 100 kilometers around the trunk, and six huge chains hung down from the sky and connected to the six huge stone pillars on the edge of the altar.

Colorful energy rays continued to emanate from the chains, and if you looked closely, some of these chains were like flames, some were like flowing water, some were like ice crystals, and some were like wind knives, entangled and condensed with each other, forming these six huge chains.

It seems that this is another place where the demons are used to suppress the underworld, but this skeleton frame is at least ten thousand times more powerful than the undead guardian Tutkamon, because no matter in terms of the size of this altar, the scale of the formation, or the thickness and type of chains, it is not the same.

A huge skeleton nearly 100 kilometers high, if you can judge the strength by the size of your body, then this guy was definitely at least a sub-god-level underworld before, or even a main god.

Yang Ling's heart couldn't help but move, remembering what the palace of the god of death and the big skeleton that kept popping up in the demon abyss had said.

Could it be ...... Is this guy the Grim Reaper Colatu?

And this idea did not come out of thin air, one is that the big skeleton has said several times that he can't feel the call of death, that is to say, the god of death is not in the underworld, and the second is, the big skeleton also said that his god seal can not communicate, this situation shows that the god of death may have hung up, because only the dead god can not support the god seal, the third is that a billion years ago the magic civilization attacked the underworld through the gate of hell, the big skull once said that the god of death is just responsible for guarding the gate of hell, according to the strength of a main god, even if the demon army is strong, it can at least block a lot of time, and will never let the demon easily attack the underworld, the only possibility is that the demon plan in advance, and killed the Grim Reaper at the beginning, so that with the cooperation of the three wolves, the inside and outside should open the gates of hell and attack it.

Yang Ling felt that there was nothing wrong with his speculation.

And according to the experience of rescuing the big skeleton last time, it seems that this bigger skeleton should not be dead, although it has been bound by the chains of the six rules for more than a billion years, but it should be this guy who went out to catch the spirit seed just now, because Yang Ling fell on one of the big skeleton's hands at this time, and found that sure enough, one of his index fingers had been broken.

Just as Yang Ling was thinking about how to verify his idea, a green light suddenly flashed above the altar, and a spirit seed tree more than two hundred meters tall suddenly fell.

"Oops!" Yang Ling stretched out his hand and grabbed it, and the power of his divine soul turned into a giant hand and grabbed at the Spirit Seed Big Tree, but just as the big hand reached the edge of the altar.

"Boom~~"

A stream of colorful light rose into the air, and the entire altar trembled slightly, and a rune-churning energy barrier blocked Yang Ling's big hand.

The green light flashed and disappeared, Yang Ling could only watch as the green spirit seed tree merged into the huge dead tree, and almost instantly, a faint green light emanated from the dead tree in the center of the altar for an unknown number of years, and the dry and cracked bark slowly revealed a trace of green, and leaf buds began to sprout on some branches.

"Quack Quack~"

The huge skeleton that had never had any life suddenly let out a ghost crying wolf howl, and then a terrifying aura emanated, and Yang Ling was caught off guard and felt that his soul was almost shaken away by this terrifying aura.

It was terrifying, Yang Ling's body shook and retreated for hundreds of kilometers, looking at the big skeleton that was constantly struggling on the altar with a pale face.

"Quack Quack~"

As the green of the huge dead tree became brighter and brighter, the green leaves began to sprout, and the branches began to stretch out and continue to wrap around the skeleton, and Yang Ling also found that wherever the green light shines, the golden skeleton of the big skeleton will begin to decay, turning into golden powder and constantly drifting down, and the position of the branches is entangled, the bones dissolve faster, and I saw that those tender green branches quickly strained into the bones, so Yang Ling couldn't help but take a closer look, and found that this huge skeleton frame could almost be regarded as scarred and leg bones, arm bones, ribs and even the skull, everywhere are mottled and rough like gravel, among which there are dense grooves, and even several ribs with a thickness of 100 meters have been almost broken, and what is even more terrifying is the spine of the skeleton, which is tightly tied to the big tree by six chains, so the trunk of the big tree is like a soldering iron constantly scorching the skeleton, nearly a thousand meters thick The bones of the spine have been fragile to the point that they will be broken at any time.

So it was, Yang Ling suddenly realized.

In order to suppress this guy, the demon clan did not hesitate to use a mature spirit seed tree, this price can be said to be unprecedented, and in this long suppression, the spirit seed tree was gradually exhausted until it died.

And the huge six-pointed star formation is to continuously extract the life energy of the spirit seed from above, and over time, the stump gradually decayed and only a thin branch remained, until he resurrected it through Ling Yue'er, and the formation felt that it might not be able to suppress the big skull, so it directly absorbed the resurrected spirit seed into the dead tree and continued to suppress it, and the big skull must have felt this danger, so he was ready to destroy the spirit seed outside the altar.

It's a pity that Yang Ling stabbed off a finger with a dragon spear, which led to no success, and the big skeleton also discovered Yang Ling, and the grimace rushed into Yang Ling's divine sea, and then it was also suppressed by the Chaos Purple Golden Bell.

If this big skeleton was indeed the god of death in the underworld, then for the strength of the magic civilization, Yang Ling once again raised a few points in his heart.

Lord God, what an awesome existence, equivalent to the biggest boss of the Nine Great Holy Palaces, the top level of the True Xuan Realm, but it was not an egg, it was caught by the magic civilization, and it was suppressed into a ghost, and it was not allowed to turn over for hundreds of millions of years.

But the magical civilization is so powerful that even an existence standing on the top of everything in heaven and earth can be suppressed, why is it forced to have no way to escape and desperately attack the underworld?

Yang Ling was even a little skeptical about the authenticity of this story.

The dead tree is getting more and more vigorous at this time, and a large number of delicate branches are constantly pulled out and wrapped around the big skeleton, and the big skeleton's cry is becoming more and more terrible and fearful, but no matter how he struggles, the six chains are wrapped tighter and tighter, and the six rules of wind, water, fire, ice, space, and time are intertwined into a colorful brilliance that steames on the entire altar, slowly completely submerging the hundred-kilometer-high big skeleton.
