Holding both ends of the skeleton staircase with both hands, Zheng Dong climbed up cautiously, it is strange to say, just when he stepped on the skeleton staircase, he cultivated to the fullest and completely became an ordinary person, and the sharp bone spurs on the skeleton staircase when climbing left countless blood on his hands and feet, and even after he climbed more than a dozen sections, his feet had become an abyss.

Under the explanation of the prison spirit, he knew that this was also a rule derivation, once he stumbled and fell, his bones would be gone, and the bones of the soul were permanently locked in the bone tower, what made Zheng Dong depressed was that this staircase seemed to have no end, he had climbed at least thousands of stools but had not yet reached the end, you must know that he was now a mortal, and at this time most of his body had been consumed, if he was so afraid of going on, he was really afraid that he would miss and fall.

Fortunately, according to the prison spirit, the time in this bone tower is ten to one with the flow rate of the outside world, otherwise it would have used up the hard-won time just to climb the ladder.

Just when Zheng Dong almost ran out of patience, his body suddenly seemed to pass through a membrane, and the bone ladder under his feet had disappeared, and he entered a closed space again, and before Zheng Dong could see his body clearly, he suddenly felt a cold effect on him, as if even his soul was about to be frozen by this cold cold.

Zheng Dong found himself trapped in a sea of green fire, and the fierce burning flames brought not extreme heat but endless cold, that is, Zheng Dong mastered the Dao of Fire Rhyme to condense the heart bead of fire, and also had the fire system of the earth spirit root, otherwise he would have frozen together with his body and soul under the extreme cold, even now Zheng Dong's feeling is not very good, because the fire here is completely opposite to the fire element in his body.

"Could this be the legendary Netherworld Ghost Fire that can freeze the soul of a monk?" Zheng Dong's face was calm and faint, in fact, the cold fire was not all bad, at least his originally boiling and tumbling blood became much calmer.

"Yes, I just heard that countless monks died in the bone tower before, and I wondered why those people were so wasteful, but I didn't expect that this bone tower was far from being as simple as imagined, and the first layer dispatched the Spirit Devouring Worm. This layer is full of Netherworld Ghost Fire, although the strength is indeed not large, and the Sixth-Order Foundation Building can resist with all its strength, but these Netherworld Ghost Fires are not endless, and generally the Sixth-Order Foundation Building Monk will be frozen to death if he insists on half a pillar of incense at most, even if he reaches the Great Perfection of Foundation Building, he can't resist for half an hour. ”

"You can only compete because of various coincidences, almost no one below Jindan can compare to you in fire control, but if you are like this, you will be stuck here at most, and once the time runs out of poisonous water, you will die and have no place to be buried. Or you simply throw in the towel, because you've broken a layer of bone towers that can teleport you out according to the rules. The prison spirit said as he squinted his eyes and enjoyed the licking of the ghostly fire.

The Hell Soul Hunter Cat is originally a Netherworld Ghost Beast, and this Netherworld Ghost Fire is not only not a medium damage to it, but it can be used to refine the underworld mana in its body.

Joke, this is just the second floor of the tower, that is, the mid-stage strength of the foundation, no matter how Zhu Yan took advantage of the loopholes to increase the difficulty, the final core will not change, that is, the extreme attack here is the peak strength of the mid-stage foundation. If it were other elements, he might be helpless, and if he couldn't even subdue the flames, he wouldn't have to practice in the future.

Zheng Dong suddenly opened his mouth and inhaled hard. As he absorbed those Nether Ghost Fires and turned into a green fire dragon and threw them into his mouth and nose, after a steady stream of Nether Ghost Fire entered his body, he was led by Zheng Dong to the Fire Heart Bead, and the Nether Ghost Fire continued to pour in. The beads, which were originally red, were dyed with a layer of green, and gradually became red and green as the ghost fire continued to pour in.

It took a full quarter of an hour for Zheng Dong to completely collect the Netherworld Ghost Fire in the entire second-floor space. After receiving it, a miserable white color appeared on his face, although it was the same flame, but the Dao rhyme contained in the Netherworld Ghost Fire was different from ordinary blazing flames after all, Zheng Dong only temporarily absorbed and suppressed it, and there was still a long way to go if he wanted to use it.

As the ghostly ghost fire all disappeared, a bone ladder leading to the upper level and a golden box appeared in the dead silence of the second floor space, Zheng Dong opened it and found that the box was three large columnar spars, just when he picked up the three spars and wanted to use his divine sense to spy on them, a sharp blade appeared in the spar that he entered into his divine sense, and instantly cut off a piece of his divine consciousness.

Shocked, Zheng Dong hurriedly withdrew his divine sense, but found that his appearance had been printed on the crystal cylinder, which looked like looking in a mirror, but no matter how he squeezed his eyebrows, the images on the crystal cylinder were rigid and would not change.

Without waiting for Zheng Dong to ask, the prison spirit took the initiative to speak: "These three crystals are not things from the world, but heavenly treasures from the spirit world, which are called clone crystals, and their common use is to intercept part of the user's divine soul imprint, and then draw a clone with the same breath as the user, but the combat power is only one-third of the user's, and it is only the basic combat power, not including the power of supernatural powers." ”

"Because the level of this doppelganger crystal is not high, so the limit of transfiguration is the foundation building period, so even if it falls into the hands of the true monarch of the law phase, it is useless, fortunately, your cultivation is not high, these three crystals can be used until you are promoted to Jindan, the method of manipulation is very simple, as long as you enter a true element to activate and then manipulate it with divine consciousness, as long as it is not destroyed by powerful forces, this doppelganger crystal can be used all the time. ”

After hearing the explanation of the prison spirit, Zheng Dong immediately became very interested in the doppelganger crystal from the world in his hand, and as he entered the true yuan, the crystal turned into a pillar of smoke and flew out of his hand, and then turned into a body exactly like him, let Zheng Dong's divine sense carefully inspect it, and did not see any difference between this doppelganger and his body.

With the influx of divine consciousness into the clone, Zheng Dong suddenly felt that his entire vision was divided into two, and that clone also completely survived, Zheng Dong already had the ability to multitask, but he simply adapted to and already knew how to manipulate the body and the clone, as soon as he told the prison spirit, the true strength of the doppelganger only needs to build the fourth order of the foundation, and the physical cultivation is only the fifth level of the Dharma body realm.

Zheng Dong's mastery of the spells, his clone can also be used, including some abilities of the Dharma Body Realm, although the clone can not use the small magic power he has, but he can master the wind, fire and life and death rhyme that he comprehends, and really fight, each clone has the ability to fight against the monks in the later stage of foundation building.

In fact, combat power is still secondary, the most important thing is that the aura of the avatar is exactly the same as him, if it is used well, it can save his life at the critical moment. (To be continued......)
