Lin Ming's sabotage of Zhang Guanyu's affairs quickly spread throughout Tianyun City.

  Before this, Zhang Guanyu was the genius martial artist second only to Qin Xuan in the entire Tianyun City, a heaven-spoiled child like him, became completely useless overnight, this is an unprecedented event!

  Moreover, Lin Ming defeated Zhang Guanyu in front of Ouyang Yuhua. Ouyang Yuhua, who had already reached the Condensing Pulse stage, personally took action but was unable to stop Lin Ming.

  Then Lin Ming faced Ouyang Qianhua's oppressive momentum, not giving an inch. If it wasn't for the timely appearance of the Seventh Master of the Wu Fang, that night would have ended in a completely different way.

  This series of events made Lin Ming's image suddenly appear resolute and ruthless.

  In just two and a half months, he defeated Zhang Guanyu, and it's now clear that Lin Ming will surpass Ling Sen and Tu Suo. He is only 15 years old now, and his future achievements are boundless.

  If such a fierce man were even more resolute and ruthless...

  Thinking of this, people can't help but have an idea that Lin Ming is someone they absolutely cannot afford to offend.

  Qixing Wufu, Tian Nu Huoshan Group

  This volcano is located seven hundred miles due west of Mount Zhōu.

  This is the most active volcanic group in Tianyun Country. Walking near the volcanic mouth, the pungent sulfur gas fills the air everywhere. The rocks underfoot are hot enough to cook eggs. The lava river flows beneath your feet, and you can clearly see the bubbling magma flowing slowly like a dark red iron flow.

  Even if the ground looks fine, it can't be stepped on lightly. Because it's uncertain whether this piece of ground is just a newly solidified lava crust, and stepping on it will crush the lava crust, and the surging lava below will swallow people up.

  This is one of the Seven Killing Arrays of the Seventh Rank of the WuFu Clan - the Fire Array: Lava Cave.

  Lin Ming arrived here through the transmission array of the Seventh Underworld. Suddenly, he felt a scorching heat wave rushing towards him like fire, and the rocks under his feet were all dark red in color. Ordinary people couldn't even set foot here.

  "What a lava cave!" Lin Ming exclaimed, the lava cave and the icy pool were two extremes, one extremely hot and the other extremely cold.

  The two have similar functions, but also slightly different.

  Waterfall Cold Pool emphasizes tempering the body, allowing martial artists to resist coldness and penetrate true yuan into every inch of skin and flesh.

  The Magma Cavern focuses on refining the True Origin, as martial artists practice their skills, the True Origin will inevitably contain some impurities due to various reasons. It cannot be purified, and the role of the Magma Cavern is to allow martial artists to burn and refine the impure parts of the True Origin when using it to resist the scorching heat.

  Lin Ming cultivated the Chaotic Void Fist Scripture, his true yuan was pure and thick within his body. Originally, he didn't need to come to the Lava Cave.

  However, Lin Ming had previously taken two elixirs that directly increased his cultivation, the Hong Jin Long Gui Dan and the Jin She Chi Dan. Although these two elixirs were priceless treasures, they still left behind some impurities and medicinal toxins in Lin Ming's True Essence.

  Through these days of cultivation, Lin Ming also constantly refined away these impurities. However, there was always a bit left over, and they were not completely eliminated.

  Lin Ming must now take the Five Hundred Year Blood Lingzhi. To ensure that his True Essence remains as pure as possible, otherwise impurities will accumulate and be even more difficult to remove later on.

  "Lin Shidi, you're here." The elder brother in charge of the Lava Cave said with a smile, guarding the Lava Cave was a tough job, although warriors weren't afraid of this level of heat, but that didn't mean they liked staying in a steamer.

  "Eleventh level of difficulty, two hours, thanks Brother!"

  For the first time in Lava Cave, Lin Ming still chose the corresponding difficulty according to his own ability. As for the twelfth level of difficulty, even Ling Sen couldn't hold on for long, and he didn't plan to try it out for the time being.

  "Hmm, okay!" The steward didn't think Lin Ming's breakthrough to the 11th level was anything forced.

  Other killing arrays in the Seven Great Killing Arrays utilize array techniques to amplify natural forces, such as the Waterfall and Ice Pool Array which makes the waterfall's power greater and the ice pool colder, while the Wind Cave Array makes the wind more ferocious, creating various whirlpools and turbulent flows.

  However, this lava cave is an exception. The main function of the formation is to weaken the power of nature, causing the temperature of the lava to drop.

  Ordinary lava is ten times hotter than boiling water and even more so in the case of volcanic fire.

  Because of the volcanic eruption of Tian Nu, the iron ore was mixed into the lava, and the temperature became even higher, reaching more than twenty times that of boiling water.

  Not to mention a martial artist in the foundation-building period, even if it's a postnatal martial artist who jumps in, they'll still be burned to ashes!

  So if you want to use molten lava to refine your true yuan, you need to lower the temperature through an array method, only then can a warrior use it.

  Lin Ming chose an eleventh-level difficulty, with lava temperatures eight times that of boiling water, enough to melt many metals.

  Arriving at the eleventh level of difficulty, the Lava Cave, Lin Ming took off all his clothes, as they would immediately catch fire if they fell into the lava pool.

  Barefoot, Lin Ming stepped onto the scorching hot rocks and arrived at the lava pool. The bright red lava was like boiling iron water, reflecting a crimson glow on his face. Occasionally, large bubbles emerged from the lava, bursting open with a dull thud, releasing scorching toxic gases.

  Jumping into this lava pool requires great courage, and even some warriors with a weak heart dare not use the lava cave to cultivate.

  Lin Ming activated his True Essence to the extreme, took a deep breath, and leaped into the lava.

  "Pffft!"

  Lin Ming's feet had only sunk into the lava, but his body was slowly sinking down at a speed that was almost imperceptible. The viscosity of the lava was incredibly high, and if a warrior's speed was fast enough, they could even run on top of it.

  "It's so hot!"

  Lin Ming felt as if his feet had stepped into a boiling cauldron, and although the True Essence protected him, the scorching pain was still like a knife cut, making it hard to bear.

  The resistance was great as Lin Ming sank down, and in an instant his entire body was submerged in the fiery lava.

  A world in the midst of lava, a dark red hue, everywhere was scorching red light, visibility was zero, Lin Ming couldn't even see his own palm.

  Manipulating the true yuan to condense into a layer of true yuan gauze on the surface, however, Lin Ming could still feel the piercing pain brought by the heat flow through the true yuan gauze.

  In the waterfall's icy pool, a warrior directly contacts the icy water, drawing in cold air to temper the five organs and six viscera, bone, flesh, tendons, and membranes.

  Even in the lava cave, even the most powerful warriors dare not let **directly touch the lava. The lava contains not only heat poison but also various toxic hot gases. Inhaling a few mouthfuls can be fatal.

  So it is necessary to condense the true yuan silk, and separate the lava from it. Then carefully lead the fire of the lava into the body, burning out the impurities inside.

  This is an extremely dangerous cultivation method. Disciples who are not skilled enough can easily get their meridians burned, causing irreparable damage.

  Even if one is a well-cultivated disciple, long-term use of earth fire to refine the body can easily leave behind hidden injuries.

  So among the seven killing arrays, Lava Cave is very quiet and does not need to be booked in advance. There are always positions available at any time.

  "Hehehe!"

  Lin Ming could even hear the sound of flames burning his true essence. He didn't rush to introduce the lava fire, but instead closed his eyes and meditated for half a stick of incense time, letting his mind completely relax and enter an empty state before carefully introducing the lava fire into his body.

  A small flame, as soon as it entered Lin Ming's body, immediately burst out like a ferocious fire python, but Lin Ming's true yuan was extremely dense and no matter how hard it burst, it couldn't cause any damage.

  Lin Ming quickly subdued this strand of lava-like flames, letting it obediently circulate within his body's meridians, burning away impurities.

  The fire of the lava not only burns away impurities, but also burns away the pure and true essence. However, when the pure and true essence is burned, it can be replenished, whereas when impurities are refined, they naturally disappear.

  Lin Ming continuously introduced the magma fire into his body, and slowly, there were already dozens of strands of magma fire circulating within him.

  A small flame is nothing, but with so many flames colliding, even Lin Ming's thick true yuan couldn't help but feel a sense of being hard to control.

  His face turned bright red, his forehead bulged with blue veins, and big drops of sweat kept oozing out of his body, evaporating instantly as soon as they met the heat.

  Due to the shrinkage of Zhenyuan's silk clothes, Lin Ming's hair ends had been scorched by the flames and would break with just a touch.

  Lin Ming took out a True Essence Stone from the Xumi Ring, pinched it in his hand, and absorbed the true essence within while gritting his teeth to circulate the Chaotic True Essence Technique.

  Under such a difficult state, the impurities within Lin Ming's body were being slowly burned and refined...

  One cycle after another, impurities were constantly reduced, and the True Yuan Stones were also used up one by one.

  Half a time unit for one pure true yuan stone, this speed of burning money is something even the young masters of aristocratic families can't keep up with.

  A single Pure True Yuan Stone is worth a thousand taels of gold, equivalent to half a piece of precious equipment.

  The volcanic flames within his body grew more and more violent, every tiny unit of Lin Ming's body pulsating at the same frequency to suppress the restless flames, but even so, he found it increasingly difficult to hold on.

  Lin Ming was already considering temporarily leaving the Lava Pool, otherwise he would likely suffer damage to his meridians and possibly even burn to death!

  But leaving the lava pool halfway, the effect of refining impurities will definitely be greatly discounted.

  Lin Ming was struggling with hesitation, when a strand of molten lava surged along the main artery and into Lin Ming's heart.

  "Terrible!"

  Lin Ming was shocked in his heart. The heart is the central part of his body's qi and blood, once damaged, it may be life-threatening.

  He wanted to summon the true yuan to intercept, but it was already too late. The violent lava fire rushed into the heart chamber, surging left and right, as if wanting to blast a hole in Lin Ming's heart.

  At this moment, the evil god seed that had been dormant in Lin Ming's heart suddenly burst out, and a highly compressed killing true yuan instantly surrounded the lava fire. With a soft "puff" sound, the lava fire was directly swallowed by the evil god seed!

  "Huh?"

  Lin Ming was stunned, would the Evil Spirit Seed devour the lava's flames?

  Lin Ming used his Soul Force to probe and was shocked to discover that the lava flames had completely merged into the Evil God's seed, becoming a part of it!
