I don't know how long it took to fall, Extreme Yin finally came to the world of this abyss of fire, looking at the realm in front of him whose color had changed, Extreme Yin breathed a sigh of relief, and began to sit down to recover his strength and spiritual power according to the words of the system.

"This place is really as the system says, and it is one of the few good places in the central area. Before coming to the Central District, I didn't expect that these places didn't even have a place for me to settle down and rest. The world in front of me was a dull gray, and from time to time hot wind blew out of the huge hole behind me, carrying a large amount of gray dust in the air, making the surrounding environment choking like a coal mine. But this place doesn't have that crazy filth aura, and there is nothing that can threaten the life of the extreme yin, which is already very precious.

With a rune at will, Ji Yin opened up a light mask for himself, enjoying a moment of tranquility in the light mask, since he came to the middle area, he has not been so relaxed, without any hesitation, Ji Yin lay directly on a big stone, and quickly fell asleep.

The system did not bother this young man who was already extremely tired, and Jiyin really needed a good rest in order to create miracles in the next environment. Once you step into this hole, what is prepared for the extreme yin will be a real melting pot. When the time comes, this guy will have to endure a lot of pain in addition to defending against some strange things.

This night, Ji Yin slept for two and a half days, and after recovering from the tired state on his body, Ji Yin began to recover the strength that had been consumed a lot. After arriving at the Geochemical Realm, the ordinary Qi Rejuvenation Pill was too much for him. He had to refine a specific Qi Returning Pill for himself to restore the strength in his body. Ordinary geochemical realm powerhouses rarely fight with people anymore, and after they have a lot of consumption, they will look for a secluded place to recover the strength on their bodies. For those who are strong, this world does not make some Qi Rejuvenation Pills specifically for them, because the energy in their bodies is as vast as the ocean, and even if they eat hundreds of Qi Pills at a time, they will not be able to recover much strength. The current environment of Ji Yin determines that he must rely on different methods to restore his strength, and he does not have the conditions of others, so he can only think of some ways to restore his strength in this environment.

Ji Yin, who had already sat up, the energy in his body was circulating rapidly, and on this wasteland, he began to recover the strength in his body for the first time. In the case that this piece of Origin Qi was corroded by the filth of the monsters between heaven and earth, the amount of energy that could be used to restore the Extreme Yin was relatively small. If Extreme Yin was now above that abyss, it would be impossible for him to recover the strength in his body, and in this abyss of earth and fire, without the filthy qi of monsters, Extreme Yin would be able to obtain that scarce origin energy as a recovery. Although he had the power of mountains and rivers to help him quickly collect the energy around him, the recovery speed of the extreme yin was still not fast.

The amount of energy beside him is too small, so that Ji Yin directly recovers his strength while reciting a spell to restore his spiritual power, here, the only thing that is not affected is the recovery of spiritual power. The Extreme Yin Heart is divided into two uses, striving to quickly recover all the energy in the body, so that he can enter the huge hole behind him faster.

"The world behind is very exciting, you should be mentally prepared first, I will provide you with some extra help if necessary, but you don't want me to help you alleviate the pain or get through it easily, everything needs to be carried by yourself. When Ji Yin was recovering, the system sent him a message, Ji Yin nodded, he had never recovered his strength so leisurely, and now he could chat with others casually while recovering.

It seemed that it had taken a lot of time, but in the blink of an eye, seven days had passed, Ji Yin stretched his body, and slowly stood up, he had recovered the strength and spiritual power in his body. Always ready to enter the huge cavern behind him.

Turning around, Ji Yin first used his spiritual power to probe the cave slightly, the temperature in the cave had slowly risen, and the world that was originally gray had turned dark red. Ji Yin lifted his feet and walked in slowly, he had stayed in the sky for too long, and now he wanted to walk slowly first.

The slowly rising temperature on the surface of his body made Ji Yin frown slightly, he didn't deliberately prevent this feeling, and the heat from the epidermis made him a little uncomfortable. Extreme Yin, who practices Yin exercises, naturally can't hold a furnace, and the environment of this place is the last place that Extreme Yin wants to enter, but in order to find the legendary medicinal materials given by the system, Extreme Yin has stubbornly gone up.

"Polar Ice and Fire Lotus, if that plant doesn't use stone as an advanced material, but lets you use it as a material for advancement, it's actually not bad, that lotus flower can make your exercises raise another level again, to the level of the middle of the legend level. It wasn't until Ji Yin entered the huge cave that the system told him what the purpose of this trip was, listening to the system's words, the corners of Ji Yin's mouth twitched, although he had been prepared in his heart, but after receiving this news, Ji Yin was still not happy.

"Polar Ice and Fire Lotus, a polar plant that can only grow in the most extreme environment, a place of extreme heat and cold, if you enter that extremely cold place, you may feel a little uncomfortable, but at present, this is an extremely hot place, although I know that my cultivation is not bad now, but when I get to this kind of place, I have to shed my skin if I don't die. Jiyin smiled bitterly silently, in the next part of the road, he will really have a good life.

The burning sensation on the skin has slowly turned into a burning sensation. The Polar Yin had to begin to cover the skin with Qi to resist the intense irritating sensation that this place brings. After hesitating for a while, Ji Yin stopped, and one by one, the doors of space began to take shape rapidly in front of him. Jiyin sighed silently and rushed forward quickly.

Extreme Yin, which is advancing at such a speed, is constantly covering himself with a large amount of energy. Everything around him began to change constantly, and after the color turned dark red, Extreme Yin had already wrapped a thick layer of strength defense on his body, and the temperature of this place was too high. When he continued to construct the door of space and flew in, Ji Yin had already passed hundreds of miles in the blink of an eye, and when he arrived here, Ji Yin stopped, and the strong discomfort from his body had forced him to use eighty percent of his strength as a defense.

"Looks like I'm going to be in the heart of this place, and I'm going to be able to stand it. Ji Yin looked at the wide boundary in front of him, all around him was a dark red, and from time to time flames protruded from the surrounding rocks. The stone under the feet of the extreme yin also hit a flame, hitting the strength of the extreme yin, although this did not cause harm to the extreme yin, but it made the extreme yin calm for a long time, and began to become irritable.

"Come on, I'm going to be tortured here, I should have some realization. Ji Yin began to calm his emotions, and quickly moved towards the depths of this place, the long pain is better than the short pain, but he wants to see what kind of scene it is like when he arrives in the real abyss of earth and fire.

Soon, everything around changed again, unlike the gray and fine dust just now, the flames that erupted in the cracks of the rocks, there was already a red world in front of him, there were flames burning everywhere, the extremely high temperature around him, let Ji Yin sigh silently, this is not an ordinary place at all, these flames around me for some reason, the temperature is so high, in the outside world, even if you stay in this environment, Ji Yin will not have the slightest feeling of discomfort, but everything in this place has exceeded the cognition of Ji Yin。

"The temperature of the Abyss of Earth and Fire is two hundred times that of the normal situation in the outside world, and the existence of the Fire Abyss in the depths of the earth will form this Abyss of Earth. The system looked at Jiyin so uncomfortable, and explained the situation here to Jiyin.

"I know this place, but when I am actually there, I can feel how horrible this place is. "Ji Yin used all the strength of his whole body to wrap his whole body, and when he read those legends, Ji Yin saw this place. On top of the general description of those fonts, Ji Yin already knew that this place was by no means a good place, but when he actually came to this place, he knew that everything recorded in the legend was still too understated.

"Actually, it's the same thing as described in the legend, but for people with your physique, the degree of discomfort is definitely much greater than that of others, don't hesitate anymore, come here and rush forward, you need to feel the center of the abyss of earth and fire as soon as possible, adapt to the terrifying temperature of that place, and the next step, I will tell you what to do." "The system began to urge the extreme yin, and the extreme yin has been a little lingering here because of the problem of physical fitness. Now that he has come here, everything in front of him is unavoidable, and Ji Yin should be very clear about what he must do.

"I see, I'm in the heart of the fire abyss now. After listening to the words of the system, Jiyin gritted his teeth, and after his whole body was covered with energy, he began to use the power of space to rush forward again, the space in this place has stabilized, for Jiyin, it is just a matter of raising hands to build more than a dozen space gates in an instant, under the rapid rush of Jiyin, soon, the appearance of the center of the abyss of earth and fire will be presented in front of Jiyin's eyes...
