my world double door.

The sunlight shines through the sea, turning into golden beams that pour down on the vast seabed. In the beams, tiny plankton sparkles with glittering light, like stars in the night sky. They drift slowly with the current, like a silent plankton dance. These plankton are the basis of the seabed food chain. Their existence brings the initial vitality to the entire seabed world. Every tiny individual plays an indispensable role in this grand ecosystem.

Continue to go deeper, and a colorful coral reef appears in front of you, like an underwater garden. These corals have different shapes. Some are like antlers, luxuriant and spreading, layer by layer, providing a habitat for many marine creatures; some are like huge mushrooms, round and thick, with delicate textures on the surface, shining softly under the caress of the sea water; and some are shaped like blooming flowers, with slender and soft petals, swaying gently with the water flow, exuding charming charm. The colors of the corals are even more colorful, red like fire, burning the passion of the seabed; pink like clouds, dyeing a gentle dream; yellow like gold, shining with the brilliance of life; green like emerald, telling of vitality and hope. In this coral reef, all kinds of tropical fish shuttle, they are covered with colorful scales, like flowing gems. Some fish have bright stripes, blue and white, like the fusion of sky and sea; some are pure colors, as bright and dazzling as rubies, or as deep and mysterious as sapphires; others have peculiar patterns, with spots and stripes intertwined, forming unique abstract paintings. They swim and play among the coral reefs, sometimes shuttling quickly, sometimes leisurely, adding a lively atmosphere to this underwater garden.

Not far away, a group of jellyfish floated gracefully, like transparent parachutes, lightly suspended in the sea water. The jellyfish's body exuded soft blue or purple light, like a dream, and its tentacles were as slender as silk, swaying with the swing of its body. Their swimming posture was graceful and slow, as if they were dancing a silent ballet, and every movement was full of poetry and tranquility. When the light passed through the jellyfish's body, it refracted colorful light, like an elf under the sea, exuding a mysterious and charming atmosphere.

The sand on the seabed is not barren, but has a unique landscape. The fine sand forms ripples under the action of the water flow, just like sand dunes in the desert. Some seaweed grows on the sand, and their slender leaves sway with the water flow, as if telling the story of the seabed. Occasionally, you can see some shells and starfish lying quietly on the sand. The shells of shells have exquisite patterns, and starfish become embellishments on the sand with their unique pentagonal shape and bright colors.

Deep in the sea, there are mysterious underwater caves. The entrance of the cave is covered by seaweed and corals, looming. Entering the cave, there is a mysterious atmosphere inside. Some luminous algae grow on the cave wall, bringing a faint light to the cave. Occasionally, some small marine creatures shuttle through the cave, looking for shelter here, which also adds vitality to the cave.

As night falls, the underwater world does not fall into darkness, but presents another mysterious scene. Some marine creatures begin to emit fluorescence, like bright lights illuminating the surrounding seawater. Fluorescent shrimps flash blue light and swim in groups, like a flowing galaxy; the eyes and bodies of deep-sea fish also emit fluorescence of various colors, and they shuttle through the darkness like shooting stars in the night sky. These fluorescent creatures form a sharp contrast with the surrounding darkness, creating a mysterious and magical atmosphere, making people feel as if they are in a fairy-tale world.

This underwater world is a masterpiece carved by nature with its uncanny craftsmanship. Every scene contains the miracles and mysteries of life, and every creature is a lively brushstroke in this blue painting. Together, they constitute an underwater home full of vitality and beauty, which makes people intoxicated and reluctant to leave, exploring the endless beauty and mystery in this blue dream.

"No wonder these monsters refuse to leave. I didn't expect there are so many treasures here."

In the Abyss of Shadows, after a thorough search, Li Yang spoke with joy as he felt the treasures he had collected, and his heart moved slightly.

"It's just right. I'll take this opportunity to consolidate my cultivation."

Li Yang's heart moved secretly. He looked around and chose a cave with relatively rich spiritual energy and a relatively hidden terrain as a place to practice.

After entering the cave, he first released Canghai Lingxi, then immediately sat cross-legged, closed his eyes and concentrated, and began to mobilize the spiritual power in his body, trying to establish a connection with the dark power around him. At first, the dark power surged towards him like a surging tide, violent and uncontrollable, impacting his meridians and causing him to feel a sharp pain. But Li Yang gritted his teeth and persisted with his tenacious willpower. He carefully guided this power and tried to tame it.

Canghai Lingxi quietly guarded Li Yang. It released its spiritual power and formed a light blue light shield around Li Yang to resist the erosion of the dark power. At the same time, it was also absorbing the surrounding dark energy and converting it into pure spiritual power to nourish its body and soul. Its spiritual wisdom told it that only by constantly improving its own strength could it better protect Li Yang and survive with him in this dangerous environment.

As time went by, Li Yang gradually adapted to the impact of the dark power. He began to try to integrate the dark power into his spiritual power to make it more powerful. His body trembled slightly, and sweat fell like rain, but his eyes became more determined. Every time his spiritual power was activated, it was like a fierce battle with darkness, and he would never admit defeat.

During their practice, Li Yang and Canghai Lingxi also encountered many dangers. Once, a group of shadow demon bats suddenly attacked their cave. These demon bats were emitting black mist, their eyes flashed blood-red light, and their sharp claws and teeth flashed cold light in the darkness. They surged like a tide and surrounded the cave in an instant.

Seeing this, Li Yang immediately stood up, swung the sword in his hand, and a sharp sword energy slashed at the group of demon bats. However, these demon bats were extremely agile and easily avoided his attack and continued to pounce on him. Seeing this, Canghai Lingxi roared, and a powerful spiritual light spurted out of his mouth, repelling the demon bats for a moment. But the demon bats did not give up. After circling in the air for a few times, they launched another attack.

Li Yang and Canghai Lingxi cooperated with each other. Li Yang used his sharp swordsmanship to protect his vital points while looking for the weaknesses of the group of demon bats. Canghai Lingxi continued to release the power of Lingxi to interfere with the actions of the demon bats and create opportunities for Li Yang to attack. After a fierce battle, they finally succeeded in repelling the group of demon bats, but both of them also consumed a lot of spiritual power and were exhausted.

However, they did not have time to rest for too long. Li Yang knew that in this abyss of shadows, danger could come at any time. Only by improving his cultivation as soon as possible could he better cope with everything. So, he endured the fatigue, sat cross-legged again, and continued to practice.

In the following days, Li Yang's cultivation gradually got on track. He continued to absorb the power of darkness and merge it with his own spiritual power, and his cultivation level was steadily improving. And Canghai Lingxi was also constantly evolving. Its spiritual power became purer and stronger, its body size also increased slightly, and the scales on its body became more dazzling.

Finally, one day, Li Yang felt that his cultivation was about to break through to the second level of Wuling. His spiritual power surged, as if a powerful force was ready to go. He knew that this was a critical moment, and once the breakthrough was successful, his strength would make a qualitative leap.

Li Yang took a deep breath, concentrated his mind, and used all his strength to guide the spiritual power in his body to impact the bottleneck. The dark power around him seemed to have sensed his changes, becoming more violent and rushing towards him frantically. But Li Yang was not afraid. Under the protection of Canghai Lingxi, he stubbornly resisted the impact of the dark power and moved towards a higher realm step by step. After some hard work, a crisp cracking sound suddenly came from Li Yang's body, as if a barrier that imprisoned his cultivation was broken. In an instant, a powerful breath burst out from his body, and he successfully broke through to the second level of Wuling.

Li Yang slowly opened his eyes, his eyes flashing with excitement. He felt the powerful spiritual power in his body, as well as the transformation of his body and soul. He knew that he had become stronger.

After the breakthrough, Li Yang did not become complacent. He knew that the Second Level of Wuling was just a new starting point and he still had a long way to go. So, he and Canghai Lingxi continued to practice in the Shadow Abyss, consolidating their newly broken cultivation, while also exploring more mysteries of this mysterious land to be fully prepared for future challenges.

As the days passed, Li Yang and Canghai Lingxi's practice in the Shadow Abyss became more and more in-depth. They gradually became familiar with the dark power here and were able to use it more freely to improve their strength.

Canghai Lingxi has also learned some new skills. It can compress the power of Lingxi into Lingxi balls and then launch them to cause great damage to the enemy. These Lingxi balls not only contain powerful power, but also have the ability to track, making it difficult for the enemy to dodge.

"Huh, I've almost reached the stage of cultivation."

Feeling each other's improved strength, Li Yang spoke to Canghai Lingxi with great satisfaction. After a discussion, they decided to continue exploring areas that had never been reached in this underwater world.

Li Yang was dressed in a blue suit, with the corners of his clothes fluttering like a nimble fish fin. He was agile, and every stroke of his paddle could bring up a string of crystal bubbles, which flickered in the dim light of the deep sea. His deep eyes were like a whirlpool in the night sea, hiding a desire and vigilance for the unknown. Canghai Lingxi floated beside him, his body like a flowing crystal, and the blue light emitted by the power of Lingxi dyed the surrounding sea water like a dream. Its eyes were like stars, and when it looked at Li Yang tacitly, it communicated its curiosity and determination to explore this underwater world.

They swam slowly along a beautiful coral reef ridge. The colorful corals swayed like a forest, and the agile little fish shuttled among them like stars. Li Yang gently touched the smooth corals and felt the rhythm of life at his fingertips. Suddenly, the sea water in front of him had a strange wave, as if a mysterious force was calling.

The two approached and saw an ancient underwater stone door half-hidden in the gravel. Strange runes were carved on the stone door, exuding an ancient and mysterious atmosphere. There was a faint spiritual power flowing between the runes, as if telling a story from the past. Li Yang reached out and touched the stone door, and suddenly felt a weak electric current of spiritual power coming. This was a restriction that had been precipitated over the years. Seeing this, Canghai Lingxi released the power of spiritual resonance. The blue light was like a thread wrapped around the stone door, testing and blending with the power of the restriction. Li Yang closed his eyes and concentrated, mobilizing the spiritual power in his body to explore the flaws of the restriction.

With the combined efforts of the two, the stone door slowly opened, and a dusty smell came to their faces. Behind the door was a deep passage, the walls inlaid with gems emitting dim light, illuminating the way forward. They swam in carefully, and the murals on both sides of the passage gradually came into view. The paintings depicted the scene of the ancient underwater race's sacrifice. Those strange creatures were dressed in gorgeous clothes, surrounding a huge crystal tower, with solemn and pious expressions, as if praying for the protection and blessings of the ocean. The picture was vivid, as if you could hear the chants of the past echoing in this passage.

At the end of the passage, a spacious cave suddenly appeared. In the center of the cave was a quiet spiritual spring, the spring water exuded a rich spiritual light, and wisps of spiritual power rose like smoke. Li Yang was pleasantly surprised, he knew the benefits of this spiritual spring for cultivation. He sat cross-legged beside the spring, circulated his spiritual power, and slowly absorbed the essence of the spiritual spring. The power of the spiritual spring poured into his body, like a warm current, nourishing his meridians and internal organs. Every inch of his flesh and blood was greedily absorbing this powerful power. His spiritual power became more condensed and mellow under this nourishment, and his breath became more steady and long.

Canghai Lingxi was also not idle. It probed the power of Lingxi into the bottom of the spring and found a sleeping spiritual crystal. The spiritual crystal was azure blue, and it seemed to contain a miniature ocean inside, mysterious and deep. It carefully lifted the spiritual crystal out and placed it in front of Li Yang. Li Yang took the spiritual crystal and felt the vast energy in it. The spiritual crystal resonated with his own spiritual power, as if it had found a resonant movement.

With the nourishment of the spiritual spring, Li Yang's understanding of "The Promise" has also been further improved.

He stood up and swung his fist, his fist was as powerful as a dragon, and every swing was wrapped in the rhythm of the tide. The sea water surged under the sword, forming small whirlpools, and the spiritual power in the whirlpools was surging, as if it could tear apart all obstacles. His figure shuttled flexibly in this whirlpool of spiritual power, as if he had merged with this sea area and became the master of the ocean power.

After leaving the cave, they headed deeper into the sea. Soon, a strange seabed mountain range stretched before them. Glowing plants grew on the mountain range, and the light twinkled like stars, illuminating the outline of the mountain range.

“This place is really rich in resources.”

Li Yang climbed up the mountain and carefully observed these plants. Their leaves were soft and tough, and the stems were flowing with liquid spiritual power, emitting a charming luster. He couldn't help but sigh with light in his eyes. (End of this chapter)
