Li Yi gave a wry smile, "It's easier said than done... This Nine-Headed Hydra is so formidable, equivalent to a dozen King-class fighters blocking our way. How easy could it be to get past?" Gong Wushuang spoke in a serious tone, "I can still barely exert the power of an Emperor-class fighter. Can you? If so, by joining forces, we should be able to suppress it for a while. We can use that time to dash past; everything else can be dealt with later." Li Yi closed his eyes for a moment, and after receiving some sort of confirmation, he sneered, "Fine! This Nine-Headed Hydra has bullied us enough. If we don't teach it a lesson, it will really think it's invincible!" The two exchanged a glance, and almost simultaneously, their blue and blood-red fighting auras unfolded, bringing a demonic and indescribable hue to the small cave. "Charge!" Li Yi roared and stomped on the ground, lunging forward at breakneck speed. This action enraged the Nine-Headed Hydra, whose heads lunged at him, but Li Yi waved his hand, sending several massive surges of fighting aura crashing down! Despite being equivalent to a dozen King-class fighters, each hit caused one of the Hydra's heads to slam downwards. The power of an Emperor-class fighter was not to be underestimated. However, this scene did not make the Hydra retreat. Instead, its heads shimmered with energy, obviously preparing to use its innate abilities. "Attack! We don't have time to keep tangling with this thing!" Li Yi furiously unleashed several surges of fighting aura, shouting loudly. Gong Wushuang's figure flickered, appearing beside Li Yi. Her ice-flame wings shone, and a thick layer of ice seemed to materialize in mid-air, smashing down fiercely! "Now! Let's go!" Li Yi sneered, grabbing the waist of the somewhat exhausted Gong Wushuang, who had just used her skills. Although he had a delicate and fragrant beauty in his arms, he had no mind to enjoy it. He lightly stepped on the ice, quickly darting towards the stone door... "Boom—" The ice layer behind them was shattered into powder by the dozen snake heads, and the Nine-Headed Hydra let out an indignant roar, lunging at Li Yi's retreating figure. At this moment, Li Yi's blood-red wings of fighting aura flickered slightly, increasing his already swift speed. Just as the Hydra was about to bite him, he lightly slapped his right palm, sending a surge of fighting aura backwards, smashing it into the Hydra's body. Meanwhile, his figure, using the force of the blow, landed steadily near the stone door. Standing on the stone door, Li Yi finally released Gong Wushuang's hand, only then realizing how soft and tender her slender waist was... This feeling made him somewhat conflicted, but he pretended as if nothing had happened, looking back. The ferocious Nine-Headed Hydra seemed to exhibit a human-like expression of helplessness on its many heads. Although close to Li Yi, it dared not approach any further. After lingering for a moment and confirming that Li Yi and Gong Wushuang wouldn't leave soon, it let out a reluctant roar and slowly receded into the darkness. Watching the Hydra disappear, the two exchanged a relieved glance. To have avoided the Hydra in such a state was lucky; otherwise, even using their Emperor-class strength, defeating the Nine-Headed Hydra wouldn't have been easy. Li Yi had barely borrowed the power of The Serpent Venerable, a power that was not only limited in strength but also in duration, and could easily lead to his body's collapse under the strain. As for Gong Wushuang, rashly using Emperor-class power without fully assimilating the chaotic force within her could have been disastrous. Thus, they both felt a sense of fortune at this moment. After catching their breath and calming their emotions, Li Yi stepped forward, carefully inspecting the stone door. "It seems this door can only be opened with the strength of a King-class fighter. Your turn," he said. Gong Wushuang looked at him as if he were an idiot, shaking her head in resignation, "Do you really not know, or are you pretending? If there's such a setup here, it means if we can't find a way to open this door, we must leave. If we force it open, I bet this place will turn to ashes in moments... Don't underestimate any Emperor-class fighter, even the deceased ones!" With that, Gong Wushuang approached the stone door and began a careful examination. Li Yi chuckled, "It seems you're not only a genius in cultivating fighting aura but also skilled in mechanisms and seals..." Gong Wushuang shook her head, "To walk the path of a strong fighter, one must not neglect medical skills, mechanisms, seals, strategy, tactics... Otherwise, you might suffer a loss due to these things one day and perish needlessly." Li Yi gave a strange smile, murmuring, "So cultivating fighting aura also involves comprehensive development in morals, intelligence, physique, aesthetics, and labor..." "What did you say?" "Nothing, nothing. I'm saying Sister Gong's teaching is right... Have you opened the door?" Li Yi smiled. "Not difficult. If I'm right, it should be like this..." Muttering to herself, Gong Wushuang slowly extended her right hand, gently tapping on the stone door. A flash of fighting aura light passed, and suddenly, several lines appeared on the door, forming a strange pattern like a giant eye. Then, in the eye's center, a protruding point glowed red.
"Found it!" Gong Wushuang said calmly, extending her finger and lightly pressing on the protruding part of the stone door. As she pressed, a strange creaking sound emerged, and the stone door in front of them trembled before slowly retracting upwards. As the door slid open, a blue light shone from inside. This scene made Li Yi exhale in relief, "Let's see what treasures lie within... Given the fierce battle they waged, there should be something valuable here..." Watching the stone door slide up, Gong Wushuang's expression was slightly peculiar, but then she sighed, "Let's go in." Smiling, Li Yi flicked a few surges of fighting aura to ensure there were no anomalies inside, and then gestured for Gong Wushuang to enter first before stepping in himself.
Gong Wushuang followed, and as their feet touched the floor, the stone door slammed shut behind them with a 'clack,' trapping them inside the tomb chamber. They exchanged a glance; Gong Wushuang was about to speak when Li Yi smiled lightly, "If there's a way in, there's a way out. If needed, we can just break through the door. I don't believe there's no exit. Let's first see what treasures we can find." He then began surveying the interior of the tomb chamber.
The chamber behind the door appeared quite lavish. Scattered around were various gold and silver treasures, many of which were priceless artifacts. Gong Wushuang might have been indifferent, but Li Yi, who was not wealthy, was dazzled by the sight... To increase his cultivation, he needed high-quality weapons imbued with vital energy, but such items were extremely costly. Although the Li family was affluent, they wouldn't allow Li Yi to squander resources freely, so the sight of these treasures, worth at least several million gold coins, made him salivate. However, these treasures alone were not worth the effort and danger they had endured. His gaze shifted and landed on a green stone platform in the center of the chamber, upon which lay a large coffin. This was evidently the final resting place of the fallen Emperor... In the Martial Deity Continent, the bodies of strong fighters contained many secrets. Starting from the King-class level, unless specially treated, the bodies did not decompose. Thus, the Emperor's body in the coffin was likely still intact... Setting aside everything else, this body alone was probably worth countless times more than the treasures.
Of course, if the Martial Deity Tomb contained only these two items, it probably wouldn't be of much value. Frowning, Li Yi looked around and murmured, "Could it be just these treasures and the Emperor's body? Was the Beidou Sect so anxious for this reason? Or is it because this Emperor was one of their ancestors?" Gong Wushuang chuckled, "You naive fellow, the bodies of fallen Emperors from the Beidou Sect's history are kept in their sect's forbidden area. You can't make such wild guesses. The real treasures are probably hidden..." She quickly circled the chamber and then stood by the wall opposite the entrance, whispering, "If I'm not mistaken, the real treasures should be hidden here... But there might be dangers inside, so we should be careful." Li Yi walked over cautiously and nodded in agreement.
After pondering for a moment, Gong Wushuang quickly pressed a few spots on the wall. This time, there was no sound, but as they were wondering, the wall silently slid open, revealing a smaller stone chamber inside. Inside the chamber, four austere nanmu boxes were placed side by side. The boxes shimmered with an eerie glow, reminiscent of Pandora's box. The two exchanged a glance, each inhaling sharply, knowing that the truly useful items were likely inside these boxes.
After a moment's hesitation, Li Yi stepped into the chamber and cautiously approached the first box. He gently infused a wisp of fighting aura into the box to ensure it was safe. Once confirmed, he waved his hand, and a surge of fighting aura silently opened the box, lifting it towards them... Being cautious, they were well-coordinated in handling such situations. As Li Yi moved his hand, Gong Wushuang acted simultaneously, placing a sliver of ice crystal precisely where the box had been. This way, even if there were any traps, they would not be triggered.
After completing these preparations, Li Yi carefully placed the box on the ground, and their eyes simultaneously focused on the contents. In situations like this, even fathers and brothers might turn against each other for such treasures, but the relationship between Li Yi and Gong Wushuang was so peculiar that neither worried about this. Inside the ancient box, a fiery red scroll shimmered with a red light. After a moment's hesitation, Li Yi gently drew it into his hand and slowly unfolded it... "Nanming Liu Huo Jue, a fire-element technique, a low-tier skill from Baihu!" The scroll didn't have much description, but these few words said it all... A low-tier skill from Baihu? A technique of the Baihu level? Li Yi's gaze met Gong Wushuang's, both clearly seeing the shock... and the excitement in each other's eyes.
