I walk sideways in the game world

Ren Xiaoyao placed Master Gu's body in a secluded cave, sealing the entrance with rocks. He then turned to face Xia Lin, his eyes filled with grief. "Where are we going next?" Xia Lin's voice trembled. Master Gu's death had been a great blow to her. Ren Xiaoyao took a deep breath and forced himself to cheer up. "I remember ancient texts saying there's a cave deep in the East China Sea, and within that cave lies a treasure called the 'Heart of the Deep Sea.'"

"Heart of the Deep Sea?" Xia Lin was puzzled.

"Legend has it that possessing it allows one to breathe freely underwater and move freely," Ren Xiaoyao explained. "Master Gu's last wish was for us to find the legendary artifact, and I suspect it's somewhere in the underwater cave."

Charlene looked troubled. "But... we don't know how to swim, so how are we going to get into the underwater cave?"

Ren Xiaoyao's eyes were determined. "I will find a way. We must get the Heart of the Deep Sea!"

Xia Lin looked at Ren Xiaoyao's determined eyes and knew that she could not change his decision, so she could only agree reluctantly.

After many twists and turns, Ren Xiaoyao and Xia Lin finally found the entrance to the legendary underwater cave. It was a huge whirlpool, and the sea water rushed into it frantically, making a deafening roar.

"Are we really going down?" Looking at the bottomless vortex in front of her, Xia Lin's heart was filled with fear.

"Don't worry, I will protect you." Ren Xiaoyao said, taking out a water-repellent bead from his arms. This was a treasure he had obtained from the ancient tomb before. It could form a barrier to isolate water flow in a short time.

"This..." Xia Lin was still a little hesitant.

"Trust me!" Ren Xiaoyao stuffed the water-repellent beads into Xia Lin's hands, without giving her a chance to refuse, and jumped into the whirlpool.

Xia Lin looked at Ren Xiaoyao disappearing in the whirlpool, feeling extremely anxious but helpless. She could only hold the water-repellent beads tightly in her hand and jumped in as well.

However, the moment they entered the vortex, a huge black shadow slowly rose from the depths of the seabed. A pair of dark green eyes stared at them coldly, like a messenger from hell...

"Be careful!" Ren Xiaoyao pulled Xia Lin behind him and looked at the behemoth in front of him with caution...

The icy water enveloped Xia Lin, and she felt a suffocating and terrified sensation. The water-repellent beads emitted a faint glow, barely creating a small space to keep the water out. Xia Lin was still trembling when she saw Ren Xiaoyao staring intently ahead, his eyes filled with vigilance.

Following his gaze, Charlene saw a massive black figure. It was a giant siren, with octopus-like tentacles and a ferocious face, its dark green eyes gleaming with a cold light.

"Humans, how dare you trespass into my territory!" The siren made a low sound, causing the sea water to surge.

Ren Xiaoyao protected Xia Lin behind him and said in a deep voice, "We have no ill intentions. We just want to enter the underwater cave to look for something."

"How dare you! Everything here belongs to me, don't even think about touching it!" The siren roared and waved its huge tentacles towards Ren Xiaoyao.

Ren Xiaoyao reacted quickly, pulling Xia Lin away from the attack. At the same time, he unsheathed his sword and slashed the sea monster with a sword. The sea monster's huge body dodged flexibly, and its tentacles rolled up a huge rock and smashed it towards Ren Xiaoyao.

As the two sides engaged in a fierce battle, Ren Xiaoyao suddenly sheathed his sword and shouted, "Wait a minute! We're not here to fight for treasure, but to fulfill our ancestors' wishes and search for the legendary 'Heart of the Deep Sea.' You've guarded this place for years, have you ever seen it?"

The siren paused slightly, as if touched by Ren Xiaoyao's words. It was silent for a moment, its dark green eyes fixed on Ren Xiaoyao, as if trying to judge the truth of his words.

"Are you serious?" There was a hint of hesitation in the siren's voice.

"It's absolutely true!" Ren Xiaoyao said sincerely, "I guarantee it with my life."

The siren stared at Ren Xiaoyao for a long time, then slowly lowered its tentacles and said, "I can take you to the underwater cave, but it's fraught with danger. You could die if you're not careful. Furthermore, even if you find the 'Heart of the Deep Sea,' you may not be able to take it away."

"Thank you!" Ren Xiaoyao was delighted, he knew that the mermaid had agreed to their request.

The siren's massive body led the way, with Ren Xiaoyao and Xia Lin following closely behind. The entrance to the underwater cave was lined with rocks, and the interior was pitch black, pitch black. The siren waved its tentacles, releasing balls of faint green light, illuminating the path ahead.

The cave was intricate, like a maze. Various traps were hidden within, easily triggered. Fortunately, with the guidance of the Siren, Ren Xiaoyao and Xia Lin were able to escape danger.

Along the way, Ren Xiaoyao relied on his extraordinary wisdom and courage to crack countless traps and demonstrated his amazing strength. The sea monster saw this and her opinion of Ren Xiaoyao became higher and higher.

"The final level is just ahead." The Siren stopped in front of a huge stone door and said, "Behind this door lies the 'Heart of the Deep Sea,' but to open it, we need to solve an ancient puzzle."

Ren Xiaoyao looked at the stone door before him, engraved with ancient characters. He knew this would be the final test. He took a deep breath, stared firmly at the characters on the stone door, and began to think about how to crack it.

Time ticked by, Ren Xiaoyao's brow furrowed, beads of sweat forming on his forehead. Suddenly, as if a thought struck him, a glint flashed in his eyes, and he reached out and pressed a symbol on the stone door...

With a soft "click", the stone door slowly opened, revealing a deep passage behind it...

In the dark passage, the water seemed even colder and more piercing. Ren Xiaoyao and Xia Lin followed the siren to a vast cavern. In the center, a massive blue gem hovered in mid-air, emitting a soft glow that illuminated the entire cavern. The water around the gem rippled, moving as if alive.

"That's the 'Heart of the Deep Sea'!" There was a barely perceptible tremor in the siren's tone, and its huge body looked particularly eerie under the light of the gem.

Ren Xiaoyao's eyes were drawn to the "Heart of the Deep Sea." He sensed a powerful force emanating from the gem, as if it held an infinite number of secrets. He approached the gem cautiously, reaching out to touch it, but was stopped by the Siren.

"What do you want to do?!" The siren's voice suddenly became sharp and piercing, and its huge tentacles waved, stirring up an undercurrent and forcing Ren Xiaoyao back.

Ren Xiaoyao steadied himself and looked at the mermaid in confusion. "Didn't you say that as long as we can open the stone door, we can take away the 'Heart of the Deep Sea'?"

"That was in the past!" A trace of greed flashed in the siren's eyes. "The power of the 'Heart of the Deep Sea' is too great. I will not allow anyone to get their hands on it!"

Before he could finish his words, the siren's massive tentacles swooped down on Ren Xiaoyao like lightning. Ren Xiaoyao was prepared, dodging the attack by leaning sideways. The sword in his hand transformed into a streak of silver light, piercing the siren's eyes. The siren hurriedly dodged, and its tentacles rolled up a huge rock and smashed it towards Ren Xiaoyao.

The two sides engaged in a fierce battle within the confined space, the sea surging and the cave trembling, seemingly on the verge of collapse. Ren Xiaoyao, relying on his agility and exquisite swordsmanship, engaged the massive sea monster. He discovered that while the sea monster was powerful, it was relatively slow, and its attacks relied primarily on its tentacles, leaving its head as a vulnerable point.

Having found the siren's weak spot, Ren Xiaoyao began to focus his attacks on its head. His sword shone into a series of afterimages, each strike striking directly at its vital point. The siren was forced to retreat repeatedly, roaring in anger.

Finally, Ren Xiaoyao seized the opportunity when the sea monster was careless and stabbed the sea monster's eyes with his long sword. The sea monster let out a shrill scream, and its huge body trembled violently. Dark green blood gushed out, dyeing the surrounding sea red.

"You...you dare..." The siren's voice was intermittent, and its huge body slowly fell down, causing a huge wave.

Ren Xiaoyao ignored the siren's wailing. He quickly came to the "Heart of the Deep Sea" and reached out to grasp the gem that contained such powerful strength...

A powerful energy instantly surged into Ren Xiaoyao's body, and he felt dizzy, as if the whole world was spinning. He saw Xia Lin swimming towards him anxiously, wanting to say something, but no sound came out...

"Xiaoyao..."

Ren Xiaoyao felt his consciousness gradually blurring. He tried hard to open his eyes, but his eyelids felt extremely heavy...

He vaguely felt that something was changing, and this change seemed beyond his control...

The light from the Heart of the Deep Sea grew brighter, illuminating the entire cave like daylight. Ren Xiaoyao felt a powerful force surge through his body, threatening to tear him apart. His consciousness began to blur, his body twitching uncontrollably, and the sword in his hand fell, stirring up a cloud of mud and sand on the seabed.

"Xiaoyao!" Xia Lin exclaimed, and swam towards Ren Xiaoyao desperately. However, an invisible force pushed her back, preventing her from getting even a step closer to Ren Xiaoyao.

"Boss!"

"Boss!"

The other team members also noticed something was wrong and gathered around, but were also blocked by the invisible force.

"What's going on?" someone shouted in panic.

"The Heart of the Deep Sea...it's repelling Xiaoyao!" Xia Lin's face turned pale, realizing the seriousness of the problem. The power of the Heart of the Deep Sea was too great for Xiaoyao's body to withstand.

"Then what should we do?" the team members asked anxiously.

Xia Lin bit her lip and said with a determined look, "We must bring him back! Although the Heart of the Deep Sea is powerful, it is only a treasure after all. I believe Xiaoyao can defeat it!"

She directed her team members to work together to erect a protective shield, enveloping Ren Xiaoyao and herself. She then pulled out a bead emitting a shimmering green light from her bosom and gently pressed it against Ren Xiaoyao's chest.

This is a holy medicine for healing that she spent several years refining using deep-sea corals and her own blood. It has powerful healing abilities.

The green light slowly merged into Ren Xiaoyao's body. His complexion improved slightly, but his breathing was still weak, as if it would stop at any time.

Xia Lin did not dare to slack off at all. She continuously injected her spiritual power into Ren Xiaoyao's body, trying to awaken his consciousness.

As time passed, the atmosphere in the cave grew increasingly tense. Just as everyone was about to despair, Ren Xiaoyao's fingers suddenly moved slightly.

Seeing this, Xia Lin felt a glimmer of hope in her heart. She focused more on injecting her spiritual power into Ren Xiaoyao's body, while softly calling his name:

"Xiaoyao... wake up... I'm Xia Lin..."

"Xiaoyao...we still need you..."

After an unknown amount of time, Ren Xiaoyao's eyelids finally trembled slightly, and then slowly opened.

"Charlene..." His voice was hoarse and his consciousness was still a little fuzzy.

"You're awake!" Charlene was surprised and delighted, tears welling up in her eyes.

"What happened..." Ren Xiaoyao wanted to get up, but he felt weak all over and could only ask weakly.

"The Heart of the Deep Sea...its power..." Xia Lin simply told Ren Xiaoyao what had happened.

After hearing this, Ren Xiaoyao's eyes flashed with fear. He looked down at the Deep Sea Heart in his hand, which was emitting a faint blue light, and muttered to himself, "It seems that I need more time to control it..."

After saying this, he raised his head and looked firmly into the depths of the cave. There, it seemed that even more powerful forces were waiting for him to explore...

"Come on," he whispered, "We should leave."
