The bell chanted into the distance, and gradually disappeared, and an old voice seemed to come from the tower, deeper than the bell, and shook people's eardrums.

"Open the palace door!"

After the old voice sounded, the earth trembled, the space distorted, and I saw a pitch-black door slowly open, as if leading to hell, as if leading to the distant past.

A strange aura of hot and icy cold seeped out, making this world hot and cold for a second.

"One hot and one cold, one yang and one yin, this is ......"

Feeling this strange aura of hot and icy cold, Chen Zheng's pupils shrank suddenly, and he felt more and more that this underground palace was extremely mysterious, and his palm was also clenched tightly at this moment.

"Enter the palace!"

The old man's voice sounded again, and immediately all the martial artists of the powerful forces of the Inner Sect on the clearing, who were cross-legged and closed, suddenly opened their eyes and suddenly got up. I could only hear the sound of the breaking wind, and one after another figures shot towards the palace gate.

"Let's go, let's go in too. ”

Holding back the restless heart in his heart, Chen Zheng waved his hand to the brothers in the Heavenly Gate behind him, and took the lead in walking into the clearing, and then walked quickly towards the Ice and Fire Underground Palace buried deep underground.

As the distance approached, Chen Zhengfang really realized that the area of this underground palace was huge, it was only one layer above the ground, and it was actually equivalent to a two- or three-story building. The tip of the iceberg is like this, it is hard to imagine how majestic the underground palace hidden under the ground is?

Footsteps stopped a few meters in front of the dungeon, Chen Zheng got out of the way, stood aside, and carefully looked at this dungeon exuding an ancient atmosphere, the dungeon did not know what material it was built of, carved with mysterious runes like dragons and snakes, revealing heavy and vicissitudes.

It seems to be a relic left before ancient times, but the aura that emanates, sometimes scorching, sometimes cold, alternates and changes, showing that this underground palace is not a ruin, it still has a fresh vitality.

"It's really a weird place, alternating between hot and cold, and yin and yang can coexist!"

Frowning slightly, Chen Zheng was full of doubts, cold and hot, yin and yang, are diametrically opposed existences, they obviously restrain each other, but now they coexist in this underground palace, this is simply a thing that goes against common sense!

However, although he had doubts in his heart, Chen Zheng still figured out one thing, that is, this underground palace has great benefits for the cultivation of martial artists.

The basic exercise of the Wentian Sect, "Eighteen Plates of Wentian", is about the intensification of yin and yang, opening the key and breaking through to a higher realm of cultivation. This underground palace alternates between hot and cold, yin and yang are constantly interchangeable, and after entering it, you can continue to stimulate yin and yang, which can completely improve your cultivation speed!

"Let's go, let's go in too!" pulled his eyes and stared at Chen Zheng, who was in a trance, and Luo Fei urged in a low voice.

"Hmm. Smiling and nodding, Chen Zheng turned his head to look at the dark door, but for some reason, something in his body was slightly touched.

The closer he got to the gate of the Ice and Fire Dungeon, the more intense Chen Zheng's heart was beating, and a moment later, when he stood at the door of the Gate of the Dungeon, his palms were already full of sweat.

Standing at the gate, Chen Zheng took a deep breath, suppressed all the distractions in his heart, raised his footsteps, and stepped heavily into the darkness behind the gate.

The light in front of him suddenly dimmed, and then, Chen Zheng felt his feet on the hard stone surface. However, his feet stepped on the ground, and before he had time to breathe a sigh of relief, his face changed suddenly, a delicate face, in an instant, it became as red as coals, and in the next second, his fiery face instantly turned cold and iron.

In a fiery red flash, sweating profusely, and the heat on the top of his head was so hot that people wanted to take off all their clothes at once. In the moment of coldness, beads of sweat instantly condensed into ice cubes, and the heat on the top of his head instantly turned into hoarfrost, dyeing his hair white.

In just less than a breath of time, Chen Zheng walked around between scorching heat and cold, alternating between hot and cold, making his entire body feel like it was exploding.

The same situation also happened to all the twenty-one members of the Heavenly Gate, such as Luo Fei, Dai Sanjin, Guihai Yijian, Yi Min, and Song Lulu.

Chen Zheng's cultivation strength is still a little bit stronger, and some other people with slightly lower cultivation strength have already begun to stir up, obviously unable to withstand such a violent hot and cold shock.

The group stood at the door and did not move, and some of the old men of the Inner Sect who entered the underground palace from behind wanted to scold, but when they saw the situation of Chen Zheng and the others, they stopped the scolding and shouted, and some schadenfreude smiled:

"Haha! It seems that these stupid melons are new here! Breaking into the Ice and Fire Underground Palace without any defense, isn't this looking for death?"

"Hurry up and inform the elders in the palace, the first time you enter the Ice and Fire Underground Palace, if there is no action from the elders, I am afraid that they will be directly stirred into pieces by this hot and cold transformation. Some other kind-hearted old men of the Inner Sect sighed.

Of course, at this time, Chen Zheng and the others couldn't hear the words of these old men, and now they were fighting against the alternating hot and cold energy in their bodies, constantly introducing them into the martial veins, trying to digest them.

However, the speed of the alternation of heat was too fast, except for a few people such as Chen Zheng and Guihai Yijian who could barely cope with it, the others, although they knew that they should guide these two completely different energies to stimulate the martial arts, they were powerless.

"Damn, what the hell is going on?"

Chen Zheng immediately ran the Nine Heavens Star Jue at a rapid pace, channeling the energy of the cold and hot changes in his body, and stimulating the sealed Nine Stars of the Earth Martial Realm.

Although he was able to temporarily suppress the hot and cold energy, he still couldn't suppress the shock in his heart. Because he didn't use the exercises to absorb these two kinds of energy, one cold and one hot, the two energies clearly appeared in his body by themselves, and they appeared instantaneously and changed instantly.

This one is incredible!

According to Chen Zheng's previous experience, no matter how rich the aura around him was, it was impossible for it to automatically enter the human body, and he had to run the exercises to absorb and refine it.

Now these two energies, cold and hot, have entered the human body independently, which made Chen Zheng instantly have an idea that even he didn't dare to believe, these two energies have their own independent consciousness.

The source of the energy emitted by self-consciousness is definitely not simple!

Chen Zheng sighed secretly, but for a while he couldn't think of what kind of existence the thing that emitted these two energies, he released his soul power to look inward, wanting to see what was going on in his body, but he trembled, and an even stronger shock rose in his heart.

I saw that in my body, I don't know when, there were two more phantoms like dragons and snakes, one was a faint red phantom, the other was a faint blue phantom, one was scorching, and the other was cold.

In this instant, the red phantom devoured the blue phantom, destroying the cold and releasing the endless scorching heat, and the next moment, another blue phantom appeared, devouring the red phantom, destroying the scorching heat and releasing the boundless cold.

Chen Zheng couldn't help but feel a little flustered in his heart, not because these two phantoms existed beyond common sense, but because these two phantoms were obviously using his body as a battlefield and constantly attacking each other.

It is difficult to say who will win the battle of these two phantoms, but if the aftermath of this battle cannot be quickly digested, the "battlefield" will undoubtedly suffer from the destruction of Yanzhòng.

Chen Zheng didn't dare to be careless at all, and ran the "Nine Heavens Star Jue" at full speed to absorb and refine the aftermath of the two phantom battles, and constantly used cold and hot energy to stimulate the sealed knots, and he could still deal with it calmly for a while.

It's just that he saw that Luo Fei, Dai Sanjin and others were in a very early situation, and he was anxious, but he couldn't think of any way to help them, so he could only be anxious.

"Huh, Soul Phantom?" Just when Chen Zheng was full of anxiety, suddenly a vicissitudes of life and a voice with surprise sounded in his ears.

"Master!" Hearing this voice, Chen Zheng was immediately overjoyed, because this voice was not someone else's, it was his master Zhi Lao.

"Pale blue color, ethereal, frozen for thousands of miles, the god is easy to cold!" this ......" Zhi Lao muttered to himself, and after a moment, ecstasy emerged in the shocked voice, "This is the cold ice soul of the god!"

"Divine Cold Ice Soul?" his heart suddenly shook, Chen Zheng almost felt a kind of excitement that he couldn't control his feelings, and the high-speed "Nine Heavens and Stars Jue" suddenly appeared a little sluggish, and the two energies of cold and hot instantly flooded in his body, making his body red and blue for a while.

"Don't get excited! Don't get excited!" Feeling Chen Zheng's agitated mind, Yao Lao hurriedly soothed, and only after Chen Zheng stabilized again did he continue, "This kind of form, such a characteristic, is indeed a Divine Cold Ice Soul! But this is not the body of the Divine Cold Ice Soul, but only a soul projection of the Divine Cold Ice Soul. ”

"It's just a soul projection of the Cold Ice Soul?"

Hearing Zhi Lao's words, Chen Zheng was even more shocked, it was just a soul projection, it was so powerful, how powerful should the body of the Divine Cold Ice Soul be? He couldn't imagine it, he could only sigh secretly, the strange soul ranked fourth on the strange soul list was indeed the treasure of heaven and earth, extraordinary!

"By the way, master, there are two soul phantoms here, one is the soul projection of the cold ice soul, but what about the other one?" After calming down, Chen Zheng also immediately discovered this problem.

Two phantoms, one cold and one hot. The cold one is obviously the cold ice soul of the gods, and the phantom of the hot one is fighting against it, obviously not a part of the cold ice soul of the gods, it should be another kind of existence.

"The other one?" Elder Zhi's voice hesitated, "It should be a Being-Zài that is as powerful as the Cold Ice Soul of God." As for what it is, I can't see it for a while!"

"Is it asking the Heavenly Pillar?" Suddenly thinking of the Heavenly Pillar, one of the nine great artifacts, Chen Zheng asked casually. Previously, he had heard Dai Sanjin say that there was not only a Divine Cold Ice Soul in the Heavenly Sect, but also an earth-shattering Nine Great Artifacts.
