Just as Ran Yi'er's anxious and resentful eyes stared straight at him, a cold wind suddenly blew out of him, and almost instantly, the heart-piercing coldness poured on her body like a spring that quenched her thirst.

The scorching heat that she had endured for a long time was relieved by this sudden coldness, and a strong sense of comfort made her quiet, but as she got closer and closer to the bottom, this comfort was also invaded by the two heavens of ice and fire.

Ran Yi'er hesitated for a moment, and simply opened her arms to give a bear hug, as if she regarded Yu Lingfeng as a big ice cube, feeling the coolness coming from him, Fang Cai's anxiety and resentment disappeared, and even a little fluttering, as if she had forgotten the situation she was in at the moment, her face was full of comfort....

Yu Lingfeng glanced at her speechlessly, fortunately, there was the Wild Snow Style and the Frozen Realm that he had learned from Qing Chengyu, otherwise he would have been baked to a crisp today,

"Hey, don't you have some means to cool down?And my left hand is almost numb, and that big guy can't get off it, you don't need me to protect it now, why are you still sticking to me!" Yu Lingfeng hurriedly reprimanded, pulling her back from her cold and comfortable arms to the scorching reality.

"I..." After he said this, Ran Yi'er remembered, took the opportunity to leave his arms, summoned the Xuanqi Sword and stepped on it, released the true qi to drive the hand to change several times, and pulled out a barrier made of Xuanbing to protect the two of them.

"Damn, you have this spell early, I won't have to work so hard," Yu Lingfeng's burden was lightened a lot, and he was immediately relieved, but Ran Yi'er blushed, pouted and touched her red face embarrassed: "People were too excited just now and forgot, forgetting that they had learned such a spell before..."

On the way to continue the journey, Yu Lingfeng swallowed another high-grade infant spirit pill, and in the blink of an eye, he restored the loss of cultivation to eighty percent, controlling five high-grade spirit weapons around his body, and killing those flame-burning people who were densely drilled out of the holes into pools of magma.

These creatures are like the guards of the flaming heart below, burrowing endlessly around the cave walls, vowing to kill the intruders or not retreat back into the cave walls, even the skeleton cowmen are regarded as enemies.

And the only means of attack of these simple-minded humanoid flame creatures is self-detonation, and when they are near the bottom, these creatures are like crazy, desperately pounced, greatly hindering their downward pace, and Ran'er's ice barrier can withstand a moment, but it can't withstand hundreds of explosions.

One stepped on the flying sword, and the other flew down in the air, controlling the five-color lightsaber outside the barrier, constantly slashing the approaching blazes, Yu Lingfeng was also a little angry,

I'm not afraid that the enemy is so strong that I can't kill him, I'm only afraid of a large number of disgusting enemies, which won't cause you substantial damage, but it can disgust you fiercely and slow down your pace, and that's the case with him at the moment, even if he kills the red eye, it's useless.

I didn't look at it for a while, Ran Yi'er was already pale, it turned out that she had been sending true qi to the Xuanbing barrier to maintain its downward movement, swallowing a few pills but not catching up with the recovery, the closer to the underground core temperature, the faster the barrier melted, not to mention the speed of true qi recovery;

Seeing that Yu Lingfeng's face was not very good-looking, when she was manipulating the five-color flying sword to kill these approaching self-detonating monsters, she also had to cast a spell to replenish the melting barrier, and after a while, she was physically and mentally exhausted, her face was white and bloodless, and the true yuan in her body gradually withered.

"Yi'er.. I'm so tired...."Ran Yi'er, whose face was almost withered, was found by Yu Lingfeng when he turned around, and instantly flew in front of her,

"Open your mouth!" eat it," Yu Lingfeng hurriedly spoke, holding a pure white top-grade Yunling Pill in his right hand,

Ran Yi'er's lips opened slightly, but she couldn't hold it and fainted all of a sudden, Yu Lingfeng scolded secretly, the Xuan Ice Barrier lost the support of true qi transmission, and at this moment, it collapsed, and a heat force that was enough to tear the flesh broke through the barrier and drilled in, accompanied by countless blazes who drilled into the barrier, and attacked the man with an angry face on his face!

"Return!" The five-colored lightsaber was guided and flew back to him, forming a five-colored sword vortex barrier, resisting the countless bursting flames, but unable to resist the heat that tore through his body.

Yu Lingfeng pried open Ran Yi'er's chapped lips with his left hand, stuffed the best Yunling Pill into her mouth, closed his eyes and mobilized the True Yuan, forming several blizzards, rolling towards the blazes who were crawling out frantically in all directions of the cave wall!

Affected by the endless heat, the same snowstorm could not last long, but it was evaporated into mist and dispersed in a few seconds.

Yu Lingfeng was distracted to deal with those fiery beasts, and he turned around to mobilize his true qi to balance the temperature, and the top-grade infant spirit pill swallowed it without even thinking about it, and the consumption was almost as good as replenishing, the temperature released by this red flame fire heart was really terrifying, it was really as terrifying as the sun, which made him have a trace of the idea of retreating.

The house leak happened to rain overnight, and it was a coincidence that the sword intent of the Flame Sword in the Elemental Five Swords was extremely suppressed, and it was difficult to exert its combination, and the same was true for the Soft Water Sword, whose strength was reduced to the maximum, and even the water sword qi could not be released.

There was still a height of less than thirty meters left from the Red Flame Fire Heart, Yu Lingfeng rushed down towards it with a fierce face, the fireball that the Red Flame Fire Heart turned into was originally stationary, but when Yu Lingfeng got closer and closer, it began to beat wildly like a living heart.

A series of chain reactions caused the entire magma sea on the ground to rumble, all the magma originated from the red flame fire center, and under the magma sea area are countless holes, such as grid-like earth veins connected with each other, when the heart is stimulated, the veins will be congested and expanded.

The ground in the area began to crumble, and the magma sea boiled several meters like a volcano about to erupt, like a catastrophe when it struck, and the rumble caused panic among all the Skeleton Oxmen tribes near the minaret building.

King Xuan stood beside the passage to the Red Flame Heart, his face twitched slightly, he looked at the constantly flickering inscriptions on the ground and the various noises coming from the endless abyss below, and then at the blue crystal at the top of the big pit.

"Could it be that with the temperature of the red fire heart, it can't burn that fly in the nether realm?" King Xuan's gaze became extremely irritable, and the sudden vibration made him completely wake up, and he grabbed the blue crystal embedded in the top of the pit with one palm.

"Smack!" With a crisp explosion, the blue crystal was pulled out by King Xuan's huge palm along with the stone wall, and crushed into a stream of blue power, burrowing into the flesh and blood armor of his arm.

"Huh~!You go out to stabilize the situation, and wait for the king to come up," King Xuan glanced at the large number of clan elites wearing armor nearby, exhaled a long breath, and in the blink of an eye, his body shrank rapidly, and he turned into a normal human size,

Among them, a certain clan elder with a magic staff, with eight strong and strong tribal elites, struggled to carry a heavy giant axe full of inscriptions, stepped forward and respectfully handed it over.

"Go, stabilize all the clansmen," the shrunken King Xuan's physique was still seven points stronger and more powerful than all the clan members present, and his skin under the armor was as red as the scorching sun,

He easily grabbed the Flame Battle Axe, which required eight strong members to bear, walked towards the pit, and jumped off without saying a word, because of the giant axe, the speed of the fall was more than several times that of Yu Lingfeng.

"You fly of the nether realm, look for death!" A gloomy and dull cry was transmitted downward in the pit, and in an instant, it reached the ears of Yu Lingfeng, who was approaching the heart of the red flame.

"Lao Tzu still doesn't believe it, my transformation table that stores all things can't accept you today," Yu Lingfeng looked at the red flame fire heart with the heat storm that melted all things, and the distance was so close, he suddenly found that the red flame fire heart seemed to be pregnant with life, and then looked closely, it was actually a middle-aged man sitting in a red robe with vertical hair and a round of bright sun printed on his eyebrows!!
