Qin Feng was speechless and looked at the palace carefully.


    The stone walls around the palace are painted and engraved with many ferocious animal shadows, many of which he has never seen before. This kind of animal shadow is clearly only painted and engraved on the stone wall, but it seems to have a substantive breath. The oppression is diffuse and people can''t look directly at it.


    In the center of the hall, there is a huge stone platform. The stone platform is made of strange stones of unknown age, and in the center of the stone platform, there is a well. Wisps of light black air rose from above. The air around the stone platform is more viscous, and you can see small freezing points, which is a sign that the air is frozen.


    There was a breeze blowing from the top, and in a moment it turned into a black Yin wind, raging. Under the action of air pressure, most of the Yin wind blew away to the Qin wind.


    "The most Yin thing is here."


    Looking at this scene, Qin Feng nodded, his eyes slowly surging with fire. At this time, even fools know that the most Yin thing in the mouth of the red tower should be in that well.


    He grabbed a shady wind, but soon, he changed color. The bone etching chill almost blew his brain open.


    "Shit, it''s so cold?" Qin Feng was shocked. What is this most Yin thing.


    "This is the Yin wind. The wind is caused by different air temperature, which is a normal phenomenon." the red tower said, "but there are things to the Yin under the abyss. The wind hangs from there and is contaminated with the Yin cold gas on the things to the Yin, so as to form the Yin wind."


    "The Yin wind is unusual. This kind of thing contains the power of yin and cold and has great power. However, these Yin winds can only rage in this limited space, and they are only the weakest Yin wind. Otherwise, you can''t follow here."


    Licked his lips, Qin Feng slowly approached the stone platform, and the spiritual power in his body and mind were ready to go, facing possible emergencies at any time.


    Along the way, the abnormal situation did not happen. Qin Feng was close to the stone platform. The stone platform was not high, only about one meter. He jumped up easily, and then walked to the center of the stone platform. Look at the well.


    Not so much a well as a bottomless black hole.


    There are many intricate patterns carved by the well, some of which are similar to totems, quite mysterious and mysterious.


    The well is extremely dark. That kind of black is not ordinary black. It is a kind of black without impurities, pure and terrible. Because you can''t see how deep it is. You can''t even see an inch. You can only see the top layer.


    If it is not shaped like a well, it is easy to regard it as a painting painted on a stone platform.


    Qin Feng stood by the well. At the moment, Yang Qi filled his body and resisted the attack of Yin wind.


    He looked at the mysterious well like a black hole, frowned tightly, and the light black airflow floating around him. Although the force of yin and cold was stronger than ever, he couldn''t help the Yang Qi produced by Tianlei beads..


    "Do I need to go in?" Qin Feng asked in his heart.


    "Good!"


    "Just go in like this? A little impulsive!" Qin Feng''s scalp felt numb when he heard the speech. This black hole is too mysterious. He doesn''t even know what this is. Is it too reckless to go in like this.


    "No way. If you want to get something, you have to pay the corresponding price. Can you get it so easily without paying anything?"


    Hearing the speech, Qin Feng had to bite his teeth, harden his scalp, constantly draw Yang Qi from his body, wrap his whole body, and then jump into the black hole.


    Opportunity is accompanied by crisis. If you want to get something better than others, you must pay more efforts than others. He knows this truth, so now that he has come here, he can only take it as it comes. Indecision is not his principle.


    As he entered the black hole, in addition to turning his sight into darkness, there was a terrible pressure. The endless force of yin and cold came and wanted to crush it. Even with the protection of Yang, Qin Feng could vaguely feel a sharp chill.


    "Recover Yang Qi and use your body to adapt to this Yin cold force!"


    Listening to the words of the red tower, Qin Feng''s face was a little unnatural and said with a dry smile: "is it too fast? I don''t know what''s here!"


    "There is no danger here. It''s all pure Yin cold power." said the red tower, with some exclamation in his tone: "this most Yin thing is somewhat unusual. If you can refine and absorb it, it will be unimaginable for you."


    Smell speech, Qin Feng''s heart is also a little hot. If he can make the red tower use this tone, this most Yin thing is definitely a rare treasure.


    "The power of yin and cold here is all sent out by that thing. Now you are in contact with the power of adapting to Yin and cold, which is also a preliminary contact with that thing. It is also helpful for your refining later."


    Qin Feng pursed his lips and his face was a little excited: "what''s that?"


    "Here, the perception is suppressed, and I can''t say what it is now, and I''m just the guardian of the bottom inheritance, and my knowledge is limited." the tone of the red tower sank slightly, paused for a moment, and said: "but if what I expected is not bad, it may be Huang quandan!"


    "Yellow spring pill?" the strange words stunned Qin Feng.


    "The yellow spring pill is made of the Yin and evil Qi in the depths of the earth. It turns into gas in a hundred years, becomes liquid in a thousand years, and becomes a pill in ten thousand years. It gathers the Yin and evil Qi in the depths of the earth, and is compressed, forged and solidified for thousands of years. This pill contains the Yin and cold power of the earth. It is also raised by the earth. If compared, it is no less than the top ten spiritual fires in the world."


    "So cow?" Qin Feng opened his mouth in surprise.


    "Of course, if you refine it, your spiritual Yin power will become pure and complete, but." at this point, the red tower suddenly gave a heavy tone.


    "But what?" Qin Feng asked.


    After a moment of silence, the red tower suddenly asked, "do you know why this pill is called huangquandan?"


    Qin Feng shook his head and looked blankly.


    "What do you think of the word huangquan?"


    Hearing the speech, Qin Feng''s eyes suddenly widened, and his heart was filled with a cold rising, yellow spring. In legend, it seems to have something to do with hell!


    "Isn''t it? That''s a legend. There is no hell in the world. If there is, there is reincarnation. This statement is ridiculous."


    Qin Feng tried to smile and wanted to dissolve this cloudy atmosphere. But the silence of Hongta made him feel a little cold.


    "Don''t deny some things if you haven''t touched them." the tone of the red tower was very heavy and said: "there was a kind of spread that huangquandan is a thing of the underworld. It is condensed from the yellow spring liquid of the heart of the yellow spring. It can also be said that it is the heart of the yellow spring."


    "Di... Di Fu?" Qin Feng smiled unnaturally.
