The prosperity of a natural ecosystem is never determined by consumers, but rather by the underlying producers.The energy source for these primary producers largely comes from the sun, which emits infinite light and heat. Plants absorb the sun's energy, herbivores obtain energy by eating plants, and in turn provide energy for carnivores. If one were to delve into it, over 90% of the world's flora and fauna derive their energy from that eternal sun.The world of Monster Hunter also adheres to this principle; the sun is indispensable for it to have spawned such a diverse array of unique creatures. And deep within the planet flows a special energy called Leyline Energy. Is the true energy source above, then, merely an ordinary star?Logan, in his sleep, gradually began to feel his body grow hot, as if a scorching hot current was flowing through his blood vessels to his entire body. Everywhere it passed, his surrounding flesh and bones felt as if they had been burned by fire, becoming more solid and vibrant.He didn't know how long he had slept. When he opened his eyes again, the clear water in the pool beneath him had receded by half, and the wooden pool walls around him were covered in transparent crystals."That was a wonderfully comfortable sleep. Not only am I not hungry after waking up, but my body also feels stronger, and what is this energy…?"Logan could feel that, besides Leyline Energy, there was another energy circulating within his body. Compared to Leyline Energy, it was purer, hotter, and filled with a vibrant life force.If Leyline Energy was the life force of the planet beneath his feet, then this energy was the life force of the sun. Logan felt it could be called Celestial Marrow Energy. Only this powerful life force could provide enough energy for the many producers in this world, allowing their nutritional content to far exceed anything from Logan's previous life, enough to sustain those exaggerated monsters.This was an unexpected discovery that made Logan's eyes light up, and many interesting ideas instantly flashed through his mind.As his strength continuously increased, even without deliberate evolution, his absorption of Leyline Energy also synchronously strengthened. One day, it would exceed the limit a region could bear. At that point, he would either have to deliberately suppress himself or become a mobile natural disaster, like Safi'jiiva, turning a region into a lifeless wasteland.Neither of these was what he wanted, and the appearance of Celestial Marrow Energy undoubtedly offered another solution.Moreover, could this energy be absorbed by other creatures? It is known that the energy released by the sun every day is more than three times the total internal heat of the Earth. Compared to each other, they are like an ocean and a drop of water, incomparable.This was undoubtedly a huge resource. If it could be effectively utilized, it could completely foster a new ecosystem entirely different from one based on Leyline Energy.Logan looked at the frost-like crystals adhering to the pool wall. Unlike the transparent color produced by ordinary feeding, these frost-like crystals, formed through photosynthesis, had a faint golden hue, akin to the difference between regular white rock sugar and yellow rock sugar.He still needed to experiment to see if its effects had also changed with its color.A series of heavy footsteps sounded not far away. Logan turned his head and saw Zhu Peiniang climb up from below, looking disheveled. Upon seeing Logan, she immediately let out a whimper, as if pouting.Logan looked at the wounds on her body; although they looked gruesome with torn flesh, for a giant beast's robust physique, they were merely superficial, and would quickly heal even if left untreated.This was quite interesting. With this little fellow's strength, as long as she didn't encounter an Elder Dragon, she could practically walk sideways in the Ancient Forest. What kind of monster could injure her like this?Logan patted her head to comfort her, letting out a low growl, and began to inquire about what had happened.A group of monsters that looked somewhat like them, but were very ugly, and the biggest one challenged her to a one-on-one fight, but she realized something was wrong halfway through and ran back?From Zhu Peiniang's account, Logan roughly understood the outcome of the matter. He praised her alertness and then carefully asked about the appearance of those monsters, quickly confirming them to be a pack of Zinogre.So, it was an internal family affair. It seemed they had mistaken Zhu Peiniang for a wandering member trying to contend for the leader's position.When Zhu Peiniang heard from Logan that they were her own kind, she immediately showed an expression of disbelief. Shouldn't she and her boss be of the same kind? How could it be those blue monsters? Didn't this mean that no matter how big she grew, she wouldn't be able to fly?Zhu Peiniang immediately let out a series of whimpers, clearly unwilling to accept this reality. However, when she looked down at the pool in front of her, the almost identical appearance reflected in the shimmering clear water instantly made her feel like her world had collapsed.Watching Zhu Peiniang, who looked utterly dejected, Logan found it amusing. After instructing her to guard the home well and not run off, he peeled off a large amount of pale yellow frost-like crystals from the pool, then ascended into the sky on a white auspicious cloud, instantly disappearing into the distance.As Logan's figure completely vanished and her act of feigning pity failed, Zhu Peiniang immediately perked up. She plunged into the pool in front of her and began to gulp down the water, then plucked a few more crystals and crunched them loudly in her mouth.Today's food seemed to taste slightly different; it felt warm in her stomach, a unique flavor.As his strength continuously grew, Logan's range of activity also expanded accordingly. He had now successfully conquered land and sky, with only the underground and oceans remaining inaccessible.There was no need to mention underwater; if Logan was truly determined to go, it wasn't impossible. His low reliance on air combined with the electric current in his body allowed him to survive underwater for extended periods by electrolyzing oxygen, though his body structure wasn't ideally suited for it.However, he truly had no way to navigate underground. To this day, Logan couldn't understand how those monsters could pass through solid rock as easily as soft water.Yet, his growth required large quantities of rare metals, which are usually found deep underground. He had previously extorted a sum from the rich lady, and humans had also provided some, supporting his growth to nearly 27 meters in length. Now, that inexplicable hunger had returned once again.It seems he still needs to acquire the ability to excavate underground minerals. Even if he doesn't possess it himself, he can try to subdue some familiars with this ability. However, these are matters for the future; for now, Logan doesn't feel like putting in the effort.As he flew at high speed, vast stretches of forest were swept past and left far behind. Before him, an endless expanse of yellow sand appeared, with rolling hills interspersed with towering anthills, and vibrant green cacti standing proudly in the scorching heat.Not long after, Logan saw a massive black obsidian, lying elongated on the yellow sandy ground, like a scarred scab on yellow skin.This was the canyon where they had previously gone underground to search for Kulve Taroth. This time, Logan intended to try and cozy up to the rich lady again. Of course, there would be no opportunity for a sneak attack this time, and he didn't plan to use aggressive methods. Instead, he brought a gift, intending to exchange it.With a long breath, a large amount of air was drawn into Logan's combustion chamber. Special fuel was secreted, and an electric current heated it, finally transforming into a dazzling high-temperature plasma that was exhaled.As soon as the black obsidian beneath his feet touched this blue-white light, it immediately began to melt rapidly, like snow encountering boiling water. Soon, a huge depression appeared in the dark ground, and orange-red magma flowed down like honey syrup, revealing the sealed fissure below.Having had previous experience, Logan stepped down, treading on the glowing red ground, and disappeared underground in a few leaps.Following the route from his memory, he descended. The dark environment and high underground temperatures no longer put pressure on him. Even if the cave collapsed, he could forcefully carve out a path to survival with his formidable strength.Various strange stalactites flashed past his eyes, golden Scale Bats were startled from above, and unique shelled creatures lurked in the corners.Before long, Logan arrived at the end of the cave. The fissure ahead was now sealed by molten rock, but it couldn't stop him at all.As he raised his tail, a large amount of electric current converged to form high-temperature plasma, which was then constrained and shaped by a powerful magnetic field,transforming into a light blade dozens of feet long, which sliced forward.Like a hot knife cutting through butter, the hard obsidian was instantly pierced. Orange-red light rapidly diffused outwards from the light blade's center, and viscous magma then flowed down.On the other side of the wall was a cave like the Golden Land. The surrounding walls and ground seemed to be covered in molten gold, and golden stalactites overhead connected to each other, like brilliant chandeliers.A massive beast lay quietly in the center of the cave. The high temperature naturally emanating from its body had already melted the gold beneath it, creating ripples like water waves with each breath.The sound of dripping magma instantly caught the attention of this giant beast. It abruptly rose from the molten gold and looked towards the expanding opening.A familiar white figure appeared before its eyes, but its size was more than a circle larger. The dark mane on its body rose like flames, surrounded by auspicious clouds.In its long life, this was the only creature that dared to sever its horns. Even if its appearance had changed slightly, even if it turned to ash, it could still distinguish the unique metallic components within it.Invisible fury instantly surged from within, causing Kulve Taroth to let out an angry roar. Extreme high temperature erupted in the form of radiation, and silently, the entire fan-shaped area in front of it began to dissolve.The stone wall turned into magma, and the ground boiled like water. Logan stood quietly on the orange-yellow lava, having already constructed a thick electromagnetic barrier around his body. No matter how the outside world raged, he remained motionless.In these past six months, it wasn't just his size that had grown, but a comprehensive improvement of all his abilities. Even facing Kulve Taroth's enraged attack, he could handle it with composure.However, this was not unexpected by Kulve Taroth. It already knew that a simple breath of hot current would not affect the monster before it. The next moment, it slammed the ground, and the surrounding gold immediately rolled like water waves, as if summoned by some invisible force.In a short moment, they converged into a surging wave, carrying Kulve Taroth's body, and rushed towards Logan at high speed.The extremely high mass of gold generated immense force in its movement. A protruding rock, unfortunately caught in it, was instantly crushed into fine dust.However, this grand but somewhat clumsy method of attack was too easy for Logan to evade. With just a slight movement of his feet, his entire body instantly vanished from its original spot, propelled by electromagnetic force, opening up a large distance at a speed Kulve Taroth could not hope to match.Once the enraged Kulve Taroth had calmed down slightly, Logan again appeared before it with light steps. As soon as he detected any intention of attack, he immediately turned and fled.Repeating this multiple times, like desensitization training, even the strongest fury would be slowly worn away.The two giant beasts continued to pull back and forth like this. Logan wasn't worried that Kulve Taroth would, in a fit of rage, collapse the entire cave. If he remembered correctly, this place was built within the Leyline, and no Elder Dragon would dare to wantonly destroy it unless its mind was completely burned out.After an unknown amount of time, finally, when Logan appeared before Kulve Taroth again, this giant beast, covered in brilliant gold, at last did not launch an attack, but instead stared intently at Logan with angry, wary eyes.As long as they didn't start fighting upon meeting, there was a possibility of communication. After a low growl to indicate he had no ill will,Logan used an electromagnetic tendril to pick up a piece of frost-like crystal from his back and tossed it towards Kulve Taroth.The crystal, like solidified honey, traced a beautiful arc through the air, gently bounced twice upon landing,and rolled precisely to Kulve Taroth's feet.The golden giant beast immediately retreated a step cautiously, lowered its body slightly, and let out a warning low growl at Logan.Then it saw the white giant beast take out another identical crystal from its back and chew it loudly. This seemed to be a kind of food? It curiously lowered its head and sniffed lightly. Feeling no danger, it extended its tongue.The moment its tongue touched the crystal, it felt as if an electric current shot through its entire body, and a wonderful sensation instantly exploded in its mind, causing Kulve Taroth's eyes to light up involuntarily.
