Chen Su let his body go downstream, the closer he got to the center of the whirlpool, the more turbulent the water became, and the greater the impact he withwed, the strange thing is that the clear pool water became pitch black after being swept into the whirlpool, and once it was swept into the whirlpool, the pool water had no possibility of counterflow.

"Beware, the pressure in the center of this whirlpool seems to be not small!" Tian Chong reminded him, at this time Chen Su had also noticed that since he entered the whirlpool, the pressure on his body had suddenly increased exponentially, and in a short time, this power was no less than the coercion of a Danyuan Realm powerhouse, and at this time, Chen Su estimated that he should still be a few zhang away from the mysterious earth eye! The water flow is getting more and more rapid, it seems to be related to the shape of the earth eye, Chen Su has detected it with his spiritual power before, and the area around this earth eye is like an inverted funnel.

"Not good!" An idea suddenly flashed in Chen Su's mind, if this earth eye really shrank like a funnel, in case his body could not pass through that extremely thin place, judging from the increase in pressure, he was very likely to be trapped here, but at this time, it was too late for Chen Su to have this idea, just when he urged Shen Yuan, it seemed that he had touched something hard under his feet, "Is it the end?" Chen Su thought secretly, but the soles of his feet slid and his body sank down, and the huge pressure at this time was even comparable to that of a strong person in the Shezun Realm. Chen Su immediately stretched out his arms and struggled to touch the soles of his feet in the turbulence, but he felt that the place where he reached was as smooth as a mirror, greasy as grease, and there was no place to focus at all.

"Ho!" Chen Su curled his fingers into claws and grabbed forward, wanting to catch something, but this eye of the earth that has been washed by the pool of water for many years, the four walls are not only extremely smooth, but also hard and abnormal, even with Chen Su's ability, it is difficult to enter the slightest, he thinks that even the gold and stone can be pinched into powder, but he can't help the things in front of him, so he has no choice but to stop struggling, go downstream, his limbs continue to grope the surrounding sliding walls, after a few breaths, the surroundings shrink sharply, Chen Su knows that now he is really in the eye of the earth. The feet that kicked on the sliding wall suddenly emptied, and before Chen Su had time to be surprised, his body seemed to have passed through a hole, and a faint light appeared around him.

Poof!

Chen Su fell with the water, fell into a square circle of more than ten zhang in the ink pool, in the dark ink-like pool water, Chen Su urged Shen Yuan, slowly floated to the water, only then did he find that this was a large underground cave, the ink roared down from the top of the head more than three zhang high, and the ink pool below stirred up a huge splash.

"Looks like I just fell from there. Chen Su glanced up, thinking back to the huge pressure when he passed by the earth's eye, he was still a little frightened, and it was also because of the short time, otherwise he might not be able to bear it. At this moment, Chen Su suddenly felt an incomparably blazing heat burning his cheeks, and at the same time, a huge roar sounded, like a mountain torrent that had erupted, rumbling and shaking the sky.

Chen Su was startled, then stepped on the water, and his body rose in the air, but at this moment, he saw a red stream gushing out from the other side of the ink pool, which was really a "red" Flow, the scorching magma has begun to fill the river channel at some point, the extremely high temperature is even a little unbearable even for Chen Su, but his figure has to float backwards, this karst cave looks huge, magma gushing out, along the river will be the black ink pool instantly steamed into mist, the lava flowing in front of it also has a tendency to solidify because of the sudden drop in temperature, but before the red fades, the magma behind the magma gushing up will completely swallow the entire ink pool, a moment later a spectacular scene appeared, the ink pillar that descended from the sky almost to the two people to hug the ground has not yet fallen to the ground and formed a dense mist。

"The reason why there is such a warm atmosphere here seems to have come from this. Chen Su looked at it for a moment, and the magic of nature was impressive, but Huo Yuan'er let himself come down here, it shouldn't be just to see this, so his gaze turned to other places in the cave. The cave is full of rocks, because there is not only the erosion of the water but also the erosion of magma, and the surging magma will also accumulate due to cooling after encountering a huge flow of water, but it is impossible to know how such a large karst cave was formed.

Chen Su cautiously turned around in the cave, although the cave was large, it was still in the process of being sensed to him, so after a little half a moment, except for the source of the magma, he did not approach it because of the high temperature, and all the other places had been carefully explored by him.

"Could it be there?" Chen Su frowned slightly, and glanced at the place where the magma gushed out, where a small hole was arched more than a person high, and the gushing magma was also bubbling out of the hole, and after a little groaning, Chen Su urged the fire qi, and his body was wrapped in the sky-swallowing fire qi in an instant, and the same fire qi isolated him from the scorching heat, and at the same time, Chen Su's soles stepped the void, and his body swept towards the source of the magma.

The magma gushed out from the entrance of the cave, but on the wall of the cave, there was a waist-thick root vein that was as thick as something that was abrupt, red as blood, and the two ends went straight into the cave wall, and only a section appeared at the entrance of the cave, and a fist-sized nodule grew on it, which looked terrifying.

"Fire Dragon Root!" Huo Yuan'er's voice was slightly excited, and even Tian Chong's voice was a little hurried, "There is such a thing here?"

Chen Su urged the Heaven Devouring Fire Body to stand next to the entrance of the cave, looking at the rhizome like red jade inside, but he had never heard of the name Fire Dragon Root, "Huo Yuan, what is the Fire Dragon Root?"

"To Yin Fire Poison!" Huo Yuan'er's tone at this time had already shown an irrepressible mood, "Everything must be reversed, yin and yang are interconnected, and yang fire is extremely reversed and turned into yin, no wonder I have such a strong sense when I am on the top, it turns out that there is a fire dragon root hidden here, and it seems that there is also a fire dragon child." ”

"I heard that the heavenly fire is yang, and the earth's fire is yin, and now this magma is also regarded as the yin fire in the center of the earth, and the fire dragon root is really born here. Tian Chong praised and said: "Huo Yuan'er, you have made me more and more impressed, and you can actually sense this underground treasure on the ground." ”

Huo Yuan'er smiled, "Regardless of whether the heavens and the earth are the same vein, it is like my own body to me, but since I have encountered this fire dragon root today, Tunyan can finally come in handy." ”

From Huo Yuan'er's words, Chen Su knew that this root vein in front of him might be of great use to him, but the surrounding stone walls that formed this cave were extremely hard, he had tried it before, and now that this fire dragon root was growing in it, how to start made him embarrassed, "Huo Yuan, I'm afraid that this fire dragon root is difficult to obtain lightly." ”

"This is inevitable!" Huo Yuan'er said this, but his tone was very confident, "I haven't left your body since you took me out of the molten pool, it seems that I have to do it myself today!" The voice fell, and Chen Su only felt that the fire in his body suddenly rioted, but he didn't control it in the slightest, and then the light flashed in front of him, and a handsome and even somewhat bewitching figure appeared in front of him.

"Huo Yuan, so you are like this?" Chen Su was a little surprised, although he had seen Huo Yuan's true body countless times in the sky, but the Huo Yuan'er in front of him seemed to be much more handsome than the sky.

Huo Yuan'er smiled slightly, "What, are you ashamed of yourself in front of me?"

"You!" Chen Su gritted his teeth angrily and slapped Huo Yuan'er's shoulder, "I didn't expect you to be able to leave there, and I will have another good helper in the future." ”

"Hey, hey. Huo Yuan'er smiled awkwardly, "Actually, I can only hold on to half an hour now without your clearance, and I'm afraid it will take a month to condense the essence of the essence." ”

"Huh?" Chen Su opened his mouth wide, "In that case, then why did you come out?"

Huo Yuan'er glanced back at the dragon root that was knotted on the cave wall, " Of course, for it, the yin of the earth and fire is extremely poisonous, and you can't resist it with your current ability, and you look at those root nodules, which have fire dragons, all poisonous things, within seven steps, there must be an antidote, this fire dragon is the holy object that resolves the poison of the fire dragon root, but before you get the fire dragon, you must first peel off the root nodules, and this fire dragon is also the fire dragon root absorbs the earth fire condensed, with this thing, I will temper it with swallowing Yan, each time only a piece the size of a thumb is enough to supplement the fire of your current Cheng dù, and the fire poison in it can be resolved by the fire dragon。 ”

"This?" Chen Su looked at the fire dragon root a little dumbfounded, a thumb-sized piece was enough to replenish the fire qi in his body, such a huge fire dragon root, wouldn't it be an inexhaustible fire energy?" "Huo Yuan'er, then you don't hurry up and do it!" This fire dragon root is as thick as an adult's waist, and Chen Su estimates that there are at least fifty or sixty zhang underground here, so if this entire fire dragon root is used, I don't know if it can be put in his own void.

Huo Yuan'er looked at Chen Su's greedy appearance and sneered, he had figured it out with Chen Su, and he knew a little bit about what the latter thought, "You still don't have a sweet dream, although this thing is called a fire dragon root, it is because it was born in the ground, and in terms of this thickness, its length is only a few feet, but even so, it has grown for at least five hundred years, and the fire dragon root bears a fire dragon seed every thirty years, and you will know it by looking at the number of fire dragon seeds in a while." ”

"Ahh Chen Su couldn't help but be a little disappointed, after Huo Yuan'er finished speaking, he also urged the Heaven Devouring Fire Body, and the violent fire Qi swirled around him, and then he walked slowly towards the mouth of the cave where magma gushed out, "I just need to get a fire dragon seed for you first, and then the task of collecting the fire dragon root has to be left to you!"

At this time, the chaotic fire bear sleeping soundly in the cave on the ground did not know that the supreme treasure he guarded for the underworld palace had been quietly stolen.
