Zheng Dong has always acted cautiously, because he didn't know if there was any danger behind the passage, so he ordered the prison spirit to enter the exploration first, the origin of the prison spirit is in the prison of heaven and earth, as long as the prison does not destroy it, it can be immortalized, as for this hell soul hunting cat body, even if it is destroyed, it can be condensed, and the required merit value is one-tenth of the first condensation body.

After Zheng Dong stepped into the whirlpool, he opened his eyes and found that he had arrived in a dim space, the whole space had neither air nor elements, it was completely a dead silence, thanks to Zheng Dong's physical strength, it would not be much better than ordinary people to enter here as an ordinary person for ordinary law cultivation.

There is only one tower standing alone in the whole space, it is a bone tower completely made of bones, the tower body is made of hundreds of thousands of bones, the tower body is divided into three colors, the bottom bone is white, the middle bone is black, the top bone is blood red, on the top of the tower is a human head size orb, the bead emits a silver glow, there seems to be a silver mist rolling in the bead.

The prison spirit was standing in front of the bone tower waiting for Zheng Dong, but its stomach was visibly bulging compared to when it first entered, and it looked as if it had not digested it after overeating.

"When I came in just now, there were a few wandering low-level ghosts and thousands of ghosts, and I directly devoured them and sacrificed them. The prison spirit said as he slapped his tail on the ground.

Having devoured thousands of ghosts in a half-pillar of incense, Zheng Dong finally knew why the body of the prison spirit was called the Hell Soul Hunting Cat, and it seemed that it had a strong restraint against evil ghosts.

"Zhu Yan is a first-class fierce beast in ancient times, the main sword and soldier disaster, although the mature period Zhu Yan is only equivalent to the peak demon king, but with the help of the unique bloodline, the polemic power can fight to peek at the power of the early stage, this bone tower represents its juvenile period, growth period, maturity period of the three stages of the record, the white skeleton is the foundation of the monk and the demon will be left. The black bones were left by the Jindan monk and the demon handsome, and the blood-red bones were left by the Faxiang Zhenjun and the demon king. "The prison spirit is worthy of being a great encyclopedia of cultivation, and the origin of the Bone Tower is also eloquent.

Zheng Dong's words surprised Zheng Dong, Jin Dan is nothing to build a foundation, the power of the law is already the peak combat power of the realm, and the remains were actually taken by Zhu Yan to repair the tower, Zheng Dong took a rough look at the blood-red position of the spire, and found that although there were many bones there, there were actually only five kinds of subdivisions, two of which were human bones. The remaining three huge skeletons were all animal bones.

In fact, the bodies that can reach the level of the demon king are huge and abnormal, and it is also Zhu Yan who built this bone tower with only the skull and spine, if it is not so, I am afraid that the area of the bone tower will be tripled.

"Since you know so much about this bone tower, do you know what dangers are in it?" Zheng Dong said slowly as he looked at the prison spirit.

"Every Zhu Yan will build such a bone tower, and then put all the income of their life killing into the bone tower, as for the danger, this tower is twelve stories high, and each danger is aimed at a realm. The first layer of the foundation is the beginning of the foundation, as for the danger does vary from person to person, each person who enters will have a different experience, here it should be noted that the skeleton tower has a regular realm shrouded. If the person who breaks into the tower dies, the bones and spirits will be locked in the tower forever and cannot be reborn. The prison spirit said, and his tone was a little solemn.

"This means that with my current strength, even if I break into the fourth floor of the Bone Tower, there is a danger of it, and the better it is, the higher the tower. I don't know if the ancient cultivator's soul treasure is there, or if it is also in this tower. Zheng Dong frowned slightly and muttered to himself.

"You're right, but the most valuable thing in the entire Tower of Bones isn't in it. Rather, it was the source spirit bead located at the top of the tower outside, and compared to it, the so-called Zhu Yan essence blood was like dung. ”

"Zhu Yan essence blood infected ape demon beasts, so that it has a shallow Zhu Yan bloodline, if it is really integrated into the essence blood in his lifetime, the peak of the demon handsome is already the limit, this source spirit bead is different, do you know why there have never been two Zhu Yan in the small thousand world, that is because from the origin, from the ancient flood to the present, the Zhu Yan that has appeared is actually one. ”

"When each Zhu Yan dies, ninety-nine percent of the essence of the soul will shrink into a source spirit bead, absorb 100,000 years of Yin and Netherworld Qi on the bone tower, it will hatch a new Zhu Yan, and then inherit the bone tower of a qiē in a short period of time to grow into a peerless beast, during this period, once the source spirit bead is obtained by the monk, it can be integrated into the soul to cultivate into an incarnation outside the body, a doppelganger with the peak combat power of the demon king, I am afraid that no one will not be tempted under the void. ”

Although the source spirit bead is good, Zheng Dong is self-aware, and he doesn't even think about it with his own meager combat power, and now that he has passed one-tenth of an hour, he still tries his best to get some benefits.

As Zheng Dong continued to approach the Bone Tower, he felt a gloomy domain power, as he pushed the door of the Bone Tower with both hands, the entire door slowly opened inward, Zheng Dong stepped in, and suddenly felt light, the power that had suppressed his mana cultivation disappeared, and Zheng Dong's body recovered from its best condition.

As the tower door slowly closed, a puff of blue smoke suddenly rose in front of Zheng Dong, and under the scanning of his divine sense, Zheng Dong suddenly found that those were not blue smoke at all, but some small insects that were only one thousandth the size of an ant, and they suddenly made a buzzing sound, and suddenly flew over Zheng Dong.

Zheng Dong waved his hand and shot out a fire dragon when he saw it, but what surprised him was that although it was just a casual blow, the fire dragon he sent out was also tens of thousands of degrees hot, and it didn't hurt those small insects at all, and at the same time as he made a move, some small insects were already covered on his right hand.

A sharp pain came, Zheng Dong had Zhenyuan in his hand before he was devoured without even half a breath, after he reached the sixth level of the Law Body Realm, the muscle epidermis was a hundred times harder than fine iron, but under the gnawing of those small insects, it instantly became slender, and under the shock, Zheng Dong's entire arm suddenly exploded and brightened, and the epidermis and flesh were sprayed out with countless strange insects, and Zheng Dong's arm was only left with silver and bright bones.

Zheng Dong looked ugly and dodged the pursuit of the flying insects, and hurriedly asked the prison spirit, "What the hell is this?" ”

"I didn't expect you to win the jackpot this time, and you will be in big trouble at the first level, this is a spirit devouring worm, although each demon is extremely weak, and millions of them together are equivalent to the demon power of the primary demon general, but if the peak demon general has no special means, he will also drink hatred under their pursuit, because these soul devouring insects are not afraid of the attack of Yuan Li, and the hardness is better than that of Yungang and it is very difficult to deal with small and weak forces. The prison spirit quickly sent this message to Zheng Dong. (To be continued......)
