I don't know how long it took, the intense pain came, Shi Xuan opened his eyes with difficulty, but it was pitch black in front of him, there was no light, only eternal darkness. At this time, he felt a trace of warmth, a warm little hand caressed his forehead, and at the moment he was lying in a warm embrace.

"Senior sister, are you okay?" Shi Xuan shouted with difficulty, his body was in great pain at the moment, and it was difficult to mobilize even the slightest aura.

"You're awake, Shi Xuan", at this time, a familiar voice came, and Shi Xuan's hanging heart calmed down, falling from such a high place, it was a great luck to be able to survive.

"What kind of place is this, I can't see anything with my eyes, am I blind?" Shi Xuan stretched out his hand and couldn't see his five fingers.

"It should be in a cave, my leg seems to have been broken, and I don't dare to walk away, it's dark here, there is no light, so scared", Yuan Caiwei with a hint of crying, a girl was seriously injured in this dark environment, and she was already frightened to the extreme at this moment.

Feeling Yuan Caiwei's slightly trembling body, Shi Xuan knew that at this moment, Senior Sister was in an even more difficult situation than him.

"Senior sister, you help me take out the elixir from my pocket, taking the elixir can restore some aura, and it can also delay the injury", Shi Xuan forcibly mobilized the true yuan during his descent, and at this moment, many meridians were occluded, and there was no strength at all.

Yuan Caiwei's trembling hands explored his medicine bag in the darkness, took out a few bottles of the elixir he had prepared before, and ate them everywhere. The two of them didn't know how long it had been in the dark, Shi Xuan fell into a coma, and the two of them snuggled together, waiting for the verdict of fate.

Outside the cave, the volcanic eruption has stopped, and the earth has returned to calm, Zhu Ziming and Zhang Xian are like ashes at the moment, and the two of them survived, but Shi Xuan and the two fell into the bottomless cave, and the two also wanted to explore down through the rope, but they didn't see the bottom of the cave at the end of the straight rope, and they didn't respond to the sound of shouting, and after waiting for two days, the two had a premonition that Shi Xuan and they were estimated to be dead.

Zhu Ziming and Zhang Xian began to rush back to the academy, not holding out hope, such a high cave would inevitably be shattered, and the two of them looked at the road signs and rushed back to Jiahe City carefully.

At the bottom of the cave, it has been three days, and the two of them have spent an extremely difficult three days, their bodies are in pain, sometimes awake and sometimes unconscious. On the third day, Shi Xuan finally felt that the aura in his body began to turn, and the pain in his body recovered a lot, he began to urge the aura to operate, and the many blocked meridians began to operate again, his whole body once again emitted a trace of brilliance, and a small spark appeared on his hand, although it was faint, but it also illuminated the surroundings.

At this moment, Shi Xuan struggled to get up, both of them leaned against the stone wall, he looked at the weak Yuan Caiwei with the help of the faint firelight, her physical condition was not good at the moment, her right foot was broken, she couldn't stand, the fear of darkness made this usually playful and arrogant girl sit there quietly, with tears in her eyes, but she didn't cry out strongly.

Looking at Yuan Caiwei, Shi Xuan was distressed, he carefully wiped the tears from her eyes and wiped the dust off her face for her, "Trust me, we won't die here, I will take you out of here, as long as I am alive, you will not die", Shi Xuan helped her up and checked her broken leg for her.

Shi Xuan tore off some fabric, applied some elixir to her, and tied her with cloth.

In the past three days, the aura of the two people has recovered a lot, but their physical condition is extremely poor, and it is extremely difficult to walk, Shi Xuan feels that there are many dark wounds left in his body, if it were not for his terrifying defense and recovery ability of the Divine Dragon Palace, it is estimated that he will be severely disabled if he is not dead.

Yuan Caiwei's wood attribute aura has an amazing breath of life, and she is quickly repairing her injured body at the moment.

The two of them find some dry food and water bags, and if they can't find a way out here, they will only die here, and they must recover their strength as soon as possible.

"We also have some royal jelly, which is an elixir with excellent healing effect, and it can also provide us with a large amount of aura", Shi Xuan rummaged through the previous container.

Yuan Caiwei on the side looked at Shi Xuan quietly, and at this moment there was a smile on her face: "Shi Xuan, do you know? When I fell from above, I thought I was dead like this."

Shi Xuan turned his head to look at her: "Fool, you won't die if I live, and when I recover my strength, I'll start to find a way out", Shi Xuan handed some royal jelly to her mouth.

"Actually, even if I die here, I have no regrets, I have no regrets about dying with the person I like", Yuan Caiwei said calmly, she showed her heart in front of Shi Xuan for the first time.

A warm current flowed through Shi Xuan's heart, how could he have been afraid, there was such a girl who was good to him, what regrets did he have, but he thought of his parents who were worried about him at home, even if he was worried about his people at home, he had to try to go back alive.

"Do you know, in fact, when I first saw you in the Academy, I liked you", Shi Xuan said seriously, "I still remember your warm smile", Shi Xuan looked at Yuan Caiwei.

"Then you must listen to me in the future, don't bully me, otherwise I will be angry", Yuan Caiwei is like a little girl at the moment.

"I, Shi Xuan, swear to the sky, I will spend my life to protect you, if you violate this oath, heaven and earth will not tolerate it", Shi Xuan solemnly promised.

"Okay, who made you swear so much".

Shi Xuan rested and meditated for a long time, and finally regained some strength, he urged the exercises, and a spark began to illuminate the cave. He put some of the baggage he had brought in place, carried Yuan Caiwei on his back, and began to explore the cave.

The girl on her back was not heavy at all, Shi Xuan carried him on his back and walked forward cautiously, Yuan Caiwei carefully observed the surroundings, this is a rather wide cave, the age is terrifying, the two of them found that this is not a natural cave according to some traces, it should be artificially excavated in a long time.

"There are a lot of old murals on the stone walls, many of which are long lost and I don't know what age they were excavated," says Yuan.

"Since someone dug it out, then there will definitely be a way out", Shi Xuan ignited a glimmer of hope.

"You see, these murals are full of terrifying monsters, these creatures I have never heard of", Yuan Caiwei pointed to the many bizarre murals.

"Yes, the text on it is extremely ancient, I can't recognize any of it, I'm really worried that the exit is still there", Shi Xuan was a little worried.

The cave was extremely profound, the temperature in the cave was a little high, and a wave of hot air came out from the depths, "What is in it, so hot", Shi Xuan was puzzled.

"Be careful, I'm afraid that there are some demons in it, there are also some Terrans in these murals, it seems that the Terrans are fighting with these strange creatures, and both sides have suffered countless casualties, is this the passage to the demon territory?" Yuan Caiwei looked at the murals and said.

"These Terran costumes are extremely ancient, and it is estimated that they were at least 10,000 years ago, and the demons here are estimated to have been eradicated by the ancestors of the Terran Terrans, otherwise we would have died here a long time ago," Shi Xuan said.

Click, click

At this moment, Shi Xuan didn't know what he stepped on, Shi Xuan used the firelight to shine, directly startling Yuan Caiwei, in front of him was a huge demon corpse, so big that it was almost the same as some descriptions in the murals, and it was trampled by Shi Xuan at this moment.

Shi Xuan raised the firelight high, and when he looked forward, the cave was full of dust, the walls were covered with thousands of scars, and there were countless dry bones on the ground, many of which had already turned into dust, leaving only a few hard parts.

"Ah, ah, let's go back", Yuan Caiwei looked at the terrifying situation, and loudly urged Shi Xuan to return the same way, not daring to go any further.

"Don't be afraid, these demons have been dead for I don't know how many years, they have long since turned into ashes, you see that even their weapons are rotten, they have long lost their aura, we still have to move forward to find a way out", Shi Xuan comforted.

He cautiously moved forward, there were countless dry bones along the way, there were demons and Terran ancestors, he carefully avoided the remains of some Terran ancestors, and continued to move forward, the cave was chaotic, the original magnificent buildings were now in ruins, and many murals were destroyed by the battle.

"How much unknown history is buried here, how many bones of the ancestors of the human race to resist the demon army are buried, what kind of dark years are they", Shi Xuan looked at the many remaining murals and was surprised.

The outside world has long lost these legends, the quaint Jiahe City has buried too many ancient legends, and now most of the residents here come from the outside world, moving from other parts of the mainland, the ancient inhabitants here have long been missing, and their disappearance has taken away a dark age.

"Why is it that even many ancient books in the academy do not have the slightest record, why no one knows such an important history", Yuan Caiwei was also shocked.

"Maybe the answer lies in the depths of the cave, let's go and see", Shi Xuan walked towards the depths of the cave.

I don't know how far I went, it got hotter and hotter, and the heat wave made Yuan Caiwei feel extremely uncomfortable, "What the hell is it, it's so hot", Yuan Caiwei said uncomfortably.

"It's almost there, I'm extremely sensitive to the fire element," Shi Xuan continued. There seemed to be a glimmer of light in the distance.

The two of them walked towards the light, but an even more astonishing sight appeared, a huge stone bridge appeared, and beneath the stone bridge was a boiling fiery red lava, which was now tumbling and braving the heat.

"Oh my God, have we come to the center of the earth? Or are we in the center of the volcano," Yuan Caiwei exclaimed.

Shi Xuan looked at the towering stone bridge, it led to an ancient hall opposite, on the opposite side of the bridge were carved many ancient demons, with hideous faces, the whole body emitted terrifying firelight, the flames were monstrous, and the bridge went directly from the mouth carved by the demon.

Shi Xuan moved forward cautiously, if he accidentally fell, he would inevitably disappear.

At this time, the cave seemed to remember some wails left over from ancient times, low and terrifying, desolate, Yuan Caiwei hugged Shi Xuan tightly with both hands.

"Do you still want to come out and make trouble after being dead for so long?" Shi Xuan angrily felt the wails of these yin spirits, and continued to move forward, passing through the demon's throat and entering the main hall.

Ancient sighs came one after another, and both of them were so frightened that they almost fell.

"Is there still anyone alive after such a long time?" I feel like there are countless pairs of eyes looking at us", Yuan Caiwei was frightened.

"Don't be afraid, these demons have already been killed by our ancestors, it's just that some Yin Spirits are unwilling to fail and make trouble again, Yin Spirits are most afraid of Yang Fire, my True Fire Spirit is very restrained from them, don't be afraid", Shi Xuan comforted.

There has always been a strange voice in Shi Xuan's ears calling him forward, he didn't dare to tell Yuan Caiwei, this voice is a bit like the human race, he has been calling Shi Xuan forward.

There were four big characters written on a huge stone above the main hall in front, which was very simple, and Shi Xuan and the others studied it for a while, and finally determined that it was the realm of fire spirits.

"This is the place where the fire spirit was born, no wonder I feel so sensitive here, it is very compatible with my own aura", the fire element here is extremely pure and rich, far from being comparable to the outside world.

"If I can cultivate here for a long time, my strength will definitely improve by leaps and bounds", Shi Xuan felt this rich aura.

"I feel that there are still so many terrifying creatures here, they seem to be watching us all the time", Yuan Caiwei looked around, but there was no trace.

Walk into the main hall, extremely wide as a square, many carved ancient stone pillars are arranged, the stone pillars are carved with many lifelike demon statues, several huge statues stand at the end of the square, the middle one is the tallest, dozens of zhang high, the huge fangs give birth to horror, I don't know what kind of creature it is.

The largest statue held a huge battle axe in his hand, a kind of dominating the world made Shi Xuan and the two of them feel terrified, the surrounding pyramid-like hierarchy was strict, the size was from large to small, the higher the stone pillar, the taller and more terrifying the creatures on it.

"This should be the demon leader here, the others are his minions, I have seen a lot of figures in the murals before, these demons should have walked out from here", Shi Xuan said.

The two of them continued to the end and came to the back of the statue, a huge stone gate was a hundred feet high, and countless ancient runes were engraved on it, even if ten thousand years had passed, it had not been erased by time, exuding great might.

The ground in front of the gate seems to be carved with a large spirit array with a radius of 100 zhang, and in the middle is an altar, a huge divine sword is inserted into it, surrounded by runes, and the power is amazing, and the exquisite spirit array on the earth continuously absorbs the energy between heaven and earth to maintain the large array.

Above the gate, the four big characters of the Fire Spirit Temple exude divine might, the gate is sealed by this huge spirit array, and two huge human statues are carved on both sides of the gate, which are extremely powerful, and the two human statues are dozens of zhang high, each carved on the two gates.

"These two Terran ancestors should be the predecessors who blocked the demon's attack at that time, they blocked the demon's attack, and sealed the demons within this gate. This should be the place where the fire spirit was born, the realm of the fire spirit, their demon lord tried to invade our world, but was stubbornly resisted by the ancestors of the human race, and finally rolled back to their world after failure", Shi Xuan guessed.

"Why did they invade our world, and what was it like in those days, it's really unimaginable?" Yuan Caiwei sighed.

"Survival of the fittest, it has always been like this, the limited living environment and limited resources, the survival laws of countless races in order to compete for limited living space, the losers have disappeared in this world, and only the victors have become the masters of this world", Shi Xuan realized.

"Our Terran has been able to become strong thanks to the countless eras that our ancestors have fought for it and defeated countless opponents, so that the Terran has today's status, but what price have they paid?" Yuan Caiwei said with emotion.

"The countless dry bones in the passage outside are the testimonies of that era, Ru Mao drinks blood, the winner is the king, the loser is the coward, and the victory is built on countless white bones", Shi Xuan was also touched by the scene.

"That's right, the rise of the human race is based on countless dry bones, too many human sages have fallen on this road, so that they have created the prosperity of the present dynasty for us", a loud voice suddenly sounded above the main hall, Shi Xuan and the others were startled, and in a blink of an eye, on the huge stone gate, the statue on the left began to speak, and a huge spiritual light lit up around him, as if the true god was resurrected.

"Oh my God, are my predecessors immortals, and they are still alive after 10,000 years?" Yuan Caiwei exclaimed in fright.

"Junior of the Terran race, I am not an immortal but just a powerful Terran cultivator, my body has decayed thousands of years ago, this is just a trace of my remnant soul, no one in this world can stop the power of time", said a bright man in the huge light and shadow.

"Was it the senior who called me to come just now?" Shi Xuan said.

"That's right, I sensed the extreme fire spirit and the sealed golden spirit in your body, you have the rare extreme talent of this human race, I think you should have an extraordinary fate in the future, you are worthy of the old man's entrustment", the man in the light curtain said to Shi Xuan.

"With the world-shattering powers of my predecessors, do you still need the help of an Kaiyuan Realm cultivator?" Shi Xuan was puzzled.

"To put it bluntly, I have been dead for thousands of years, and the reason why the remnant soul survives in the world is to seal this fire spirit realm and prevent the demons inside from coming to the world again, if today's calamity is about to return again in the next twenty years, at that time the seal of the fire spirit realm will fall apart, this gate will be opened again, and the demons of the ancient period will reoccupy this world, and the human race will definitely face extinction at that time", the man revealed a shocking news.

"But I'm a little monk, and now I can't protect myself, how can I stop all this?" Shi Xuan was ashamed.

"Of course you can't do it now, but you almost have one or two decades to go, with your talent, I believe you can reach that height to fulfill our last wishes, I have already felt the energy of this heaven and earth revived again, within ten years the heaven and earth will be completely recovered, and then it will be very suitable for the cultivation of the human race, and a large number of powerful monks will emerge in the human race, I hope that when the time comes, you can lead a group of warriors to seal this place again, so that these animals will never be born", the man said to Shi Xuan.

"If I can grow to that point, I will definitely come here in the future to eliminate these demons forever," Shi Xuan promised.

"You can also see that the current seal has reached the end of the strong crossbow, and the sealing spell seal that took countless ancestors to build has been destroyed by the years, and there is not much time left for the human race, and the fact that you two can come here is enough to show that you are destined to help us complete the great cause", the man encouraged.

"Can I really reach the heights of yours?"

"It is not uncommon for people to be able to innate sense two elements between heaven and earth, but people who can extremely sense two elements at the same time are rare, and it is rare in the world to be able to extremely affinity with one element, and your innate talent is enough to make countless people frustrated," the man said.

"But now that I'm trapped here, life and death are unknown, whether I can get out alive is still a huge question, not to mention others", Shi Xuan thought of the embarrassing situation now.

"Who has a smooth road between heaven and earth, how can you reach the peak without going through the test of nine deaths and a lifetime, child, this is just a microcosm of your life, the road of the strong has always been ups and downs", the man warned Shi Xuan.

"I understand, I won't give up easily, what do you want me to do?"

"I can tell you the way to get out of here, but you must participate in a trial I have given you, and only through my trial will you be qualified to complete the task for us, and of course if you complete the trial, we will also give you a great opportunity. ”

"How long does the trial take?"

"I call it the Starlight Trial, you can only set down the magic seal to continue to seal the demon by finding the crystals of the heavens and stars for us, this is an extremely rare peerless spiritual material between heaven and earth, it has the power of the terrifying stars between heaven and earth enough to seal this place for 10,000 years", the man said.

"This, let me take off the stars, this is too difficult, right?" Shi Xuan was taken aback, the star crystals sounded difficult to find.

"This is only the final task, I will give you a lot of guidance, you can only take the next step if you follow my guidance and complete many tests, if the test fails, we will give up on you and find another goal."

"And what is my first mission?"

"It's very simple, live, I will give you guidance when you reach the spiritual realm in ten years, you can take this thing well, it can save your life at a critical moment, remember not to let others know, otherwise you will have to worry about your life", the man threw something from the light curtain.

Shi Xuan caught it, it was a simple spirit rune, inconspicuous in his hand, and he didn't know what it was for.

"Senior, what is this spirit rune?" Yuan Caiwei on the side was also confused.

"This is my destiny mark, there is a trace of my remnant soul in it, at the critical moment this spirit rune will tell you the task of the trial, it can provide you with three chances to save your life, when you encounter the worry of life, you can choose to use the spirit rune to save your life, remember that you can only use it three times, if the trial mission fails, I can sense it." ”

"Can only be used three times?" Shi Xuan muttered as he looked at the spirit rune in his hand.

"As long as the spirit rune activates three life-saving means, the magic circle inside will collapse, and then you can only rely on yourself, and you must think clearly when to use it. The man warned again
