Xue Rui's gaze swept around in a circle, but did not find any trace of Liu Wuxie. He asked the several disciples who were currently cultivating.

  The training ground was only this big, a man-made platform excavated, scorching heat waves, surging from the underground not far away, angry magma, like a fierce beast, swallowing and spitting out incessantly.

  The terrifying flame energy permeates the entire underground world, and cultivating here will yield twice the results with half the effort.

  For a whole day on the outside and for a month inside, the dense spiritual energy rushes into the body through the pores.

  It's indeed a wonderful place, an ideal location for cultivation. No wonder so many people want to get the qualification to cultivate in Flame Sun Cave.

  "Where did that young kid who just came in go?"

  Xue Rui Chao, who was cultivating the Xuanzi number, asked, and among them, there was another person wearing a white long gown, surprisingly, it was the Tianzi number student, whose body was surrounded by a terrifying Xiuxu realm aura.

  Frenzied inhalation, the surrounding Yang True Qi was swallowed by him, cultivating a terribly powerful technique.

  "What are you kidding me? We've been cultivating here for three days. If anyone was going to come in, it would have been you."

  Several people did not continue to pester Xue Rui, and instead devoted themselves to their cultivation. After spending a large number of academic credits, they finally exchanged for an opportunity to come and cultivate here, so how could they waste it in vain?

  They didn't lie, for three days they have been practicing here, if someone came in, how could they not know.

  He walked around the training platform in a circle, and as far as his eyes could see, there was no sign of Liu Wuxie. Where did he go?

  Xue Rui's eyebrows slightly furrowed, apart from this place, all the other branches were dead ends, once entered, there was only one way to die.

  "Hurry up and leave, don't disturb our cultivation!"

  The man in white clothes suddenly spoke up, his tone very rude, telling Xue Rui to get out of there quickly, and he was not pleased with what he had done.

  Everyone saw that Xue Rui was not qualified for cultivation, and he forcibly broke in to find someone, relying on the Xue family's big tree, ignoring the college's rules.

  Xue Rui returned to the ground with a sense of discontent. Less than half an hour later, he came up again, and Gu Zhang Lao followed Xue Pin with a puzzled face.

  "Xue Rui big brother, did you kill him?"

  Xue Pinzhi hastily asked, this kid relied on his speed and drilled in, arriving at the Flame Sun Cave, where there was only one dead end.

  "Old man, are you sure he went in?"

  Xue Rui did not answer Xue Pinzhi, asked Cha Gu's elder.

  Along the way, he checked many branch caves and didn't leave any footprints, which means that Liu Wuxie never entered the Flame Cave at all, they were all deceived.

  "A thousand truths, I saw him go in!"

  The old man patted his chest and said that he absolutely did not lie. There was no one guarding this place, so they didn't catch up.

  Xue Rui furrowed his brow, Gu Zhang Lao didn't seem to be lying, so where did Liu Wuxie go?

  "Xue Rui big brother, isn't Liu Wu Xie inside?"

  Xue Pinzhi figured it out, Xue Rui didn't actually meet Liu Wuxie.

  "The person is not inside, send someone to keep a close eye on this place, it's likely that they are hiding nearby, creating the illusion of entering, and then taking advantage of our relaxation to enter again."

  Xue Rui ordered someone from Xue Pin's side to guard this place, he didn't believe it, how long could Liu Wuxie hide.

  "Yes!"

  Xue Pinzhi nodded in agreement, and the two of them quickly left the grand hall of Yan Yang Cave, leaving Gu Zhanglao standing alone on the spot with a murderous look on his face. He had actually been deceived by Liu Wuxie.

  The dark passageway stretched out endlessly, and Liu Wuxie had been walking for nearly half an hour without reaching the end.

  The chill from the underground grew thicker, freezing him to shivers. He took out a thick garment from his storage bag and put it on to ward off the cold air.

  Tai Huang swallowed the Heavenly Key and started to revolve on his own, the cold air around him entering his body through his pores, transforming into new energy that filled his Tai Huang Dan Tian.

  This discovery made Liu Wu Xie both surprised and frightened.

  Whether it's good or bad, the sudden emergence of such a strong cold air would normally freeze anyone in the washing marrow realm into an ice stick.

  He relied on the vast and mysterious heavenly secret, combined with his strong physique, to barely make it here. No wonder he was locked up with iron chains, lest someone accidentally wandered in.

  The incoming cold air was all absorbed by the Tian Tian Ding, transformed into drop after drop of pitch-black liquid, more and more.

  Liu Wu Xie did not dare to easily pour out, and waited until he found a safe place before breaking through the boundary.

  The more liquid in the Heaven-Defying Cauldron, the higher the breakthrough boundary. Strive to break through to the high-grade Innate Realm at one go, and it won't be necessary to hold back against low-grade Washing Marrow Realm.

  A large amount of liquid appeared above the Tianyi Cauldron, with over a hundred drops accumulated. This absorption speed is terrifying.

  From Tsanglan City to Imperial City, it has been more than ten days, and all that has accumulated is just a dozen or so drops of liquid.

  Entering the Blazing Sun Cave, in just half a time unit, he condensed over 100 drops, causing Liu Wu Xie to be wildly delighted.

  The space suddenly became spacious, the cave widened, and it could accommodate two people walking shoulder to shoulder. Liu Wuxie quickened his pace.

  Rumble...

  A loud rumbling sound came from afar, as if the earth was roaring and the mountains were howling, a deafening sound that formed powerful shockwaves, reverberating back with numerous echoes.

  "This is the magma's roar!"

  Liu Wuxie quickly made a judgment. The sound of underground magma impacting rocks sounded like the roar of a wild beast.

  About ten meters in front of him, a thread of light appeared, and it was unclear where the light came from. The general outline could be seen.

  Quickened his pace, three steps made two steps, the space ahead grew wider and wider, allowing him to run quickly.

  He had just run out for less than ten meters when he suddenly stopped in his tracks. There was no road ahead of him, and facing him was a fifty-meter-wide lava river.

  The sound of galloping came from here, if it was a river of magma, why did it release the aura of cold ice, Liu Wuxie couldn't explain it clearly either.

  Boiling magma, stirring up waves several meters high, impacting the cliffs on both sides, transforming into various forms.

  In the middle of the river, a huge rock protrudes, and those rushing magma flows past this rock, stopping one after another, no longer so violent.

  "What's going on?"

  Liu Wuxie was shrouded in misty water for a moment, and it was also the first time he encountered such a situation. Could this giant stone contain some mysterious mechanism?

  Having looked for half a day, there was no clue at all, so I simply sat down.

  The position he was in was a small platform that could hold about ten people standing, and five steps forward would be an abyss, falling into the molten rock, with no chance of survival.

  Whether it's the fiery yang energy or the extreme yin energy, both have the same effect on Liu Wuxie.

  Tai Huangtun Tian Jue activated with full force, and the surrounding spiritual energy was swallowed up in an instant.

  Then, the spiritual energy from deep underground flowed in along with the magma river and all drilled into Liu Wuxie's body. The liquid in the Tian Tian Shen Ding was absorbed at an exponential rate.

  Liu Wuxie still didn't choose to break through, anyway there were ten days left, it was hard to come once, and he might as well absorb more.

  Fearsome spiritual energy formed into a liquid-like substance, swirling around Liu Wuxie's body and gathering into a spiritual rain.

  The Tian Shen Ding opened its pitch-black mouth and swallowed all the spiritual rain, forming hundreds of droplets once again.

  On the other side of the underground depths, several disciples who were cultivating suddenly opened their eyes and found that the spiritual energy in this place was actually weakening.

  Everyone looked bewildered, unsure of what had happened. Several students who were not here for the first time felt that the spiritual energy in this place was always very strong.

  Ordinary people didn't know, but Liu Wuxie discovered a spiritual vein hidden deep underground at first glance.

  The Imperial Academy was built on top of the spiritual vein, and the entire imperial capital city, where the Imperial Academy is located, has the most concentrated spiritual energy.

  These spiritual energies are all decomposed from the spiritual veins and enter deeper, the more concentrated the spiritual energy becomes.

  Ling stones are produced in the midst of spiritual veins, and the Imperial Academy absolutely does not only grasp this one spiritual vein.

  Each student can get five pieces of spiritual stone per month, which is not a small amount. Only the spiritual vein can produce a large number of spiritual stones every day.

  "It's strange, these spiritual energies seem to be flowing in one direction!"

  By following the direction of the lost spiritual energy, looking deep into the ground, it turned out to be the upstream of magma. What happened there? Why did it absorb so much spiritual energy?

  "Although it's a bit thinner, compared to outside, it's still very dense. Let's seize the time to practice, soon it will be the end of the year. The academy is going to hold an end-of-year class exchange meeting. Who doesn't want to show off their skills? This is a great opportunity to reveal one's prowess."

  Every year-end exchange, various classes compete with each other, especially those geniuses, who have been saving their strength and waiting for this day to make a stunning debut.

  After absorbing for a whole day, Liu Wuxie finally stopped devouring. Inside the Tianyi Cauldron, more than 3,000 drops of liquid were already floating, an utterly terrifying sight.

  "With this much liquid, it's no problem even if it breaks through all eight heavenly layers."

  Liu Wuxie said quietly, as for this boundary, he didn't need to worry at all.

  Ordinary people need to break through one step at a time, and each realm must be carefully carved out before it can be stabilized and then continue to break through.

  Liu Wuxie is not used, he has a Xian Emperor consciousness. Before the Xian Emperor, any realm can be continuously impacted as long as enough foundation is accumulated, and there is no situation where the realm is empty.

  Endured for so long, just waiting for this day, it's a case of gradual accumulation and sudden release.

  He took out over a hundred Tianling Dan, swallowed them down, and transformed into pure spiritual energy, impacting his four limbs and hundreds of bones. Liu Wuxie was about to make a double move.

  Not only must we break through boundaries, but also temper our bodies.

  Relying solely on breaking through boundaries, his physical body would improve along with it, but this speed was too slow. A strong and powerful physique could allow him to go even further.

  His physical body was not strong enough, and a single punch from the Overlord would be enough to tear his body apart.

  Baxing and Guīyǎnguì are his strongest trump cards, which he will never use unless he faces a life-threatening crisis.

  The poisonous scorpion and Iron Eagle's personal storage bags all fell into Liu Wuxie's hands, each of them having accumulated a considerable amount of spiritual stones.

  All poured out, and soon broke through the boundary, especially continuous breakthroughs of the boundary, requiring a large amount of spiritual stone as support. With just these spiritual energies, it was far from enough to meet his needs.

  Everything is arranged, calm and peaceful.

  "Prepare for breakthrough!"

  After accumulating for so many days, it finally made a breakthrough.

  Joining the Imperial Academy was all for this moment, to gain a large amount of resources.

  Tai Ah Tian's daily consumption of resources is terrifying, and only the Imperial Academy of the Great Yan Empire can support his consumption.

  More than three thousand drops of liquid were poured out all at once.

  Suddenly!

  A blood-curdling scream escaped from Liu Wuxie's mouth, and the tearing sensation transmitted through his tendons almost killed him.

  There is still too much Aruton in the field, and suddenly more than 3,000 drops of liquid burst out, with signs of collapse.

  This time, Liu Wuxie played a bit big, and he should have broken through his cultivation long ago. He wanted to swallow a fat man in one bite, but it wasn't that easy.

  From Aiwan.
