After returning from the spirit race, Duan Litang and his companions seemed to have returned to a peaceful state in Lingxian Academy, but the mystery of the blood covenant was like a heavy boulder, always weighing on their minds. One morning, Su Xueli brought a piece of news that ignited new hope in everyone's hearts - the Lingxian Trial Tower of Lingxian Academy was about to open. This trial tower was a mysterious place in the academy. It was said that those who passed the test would not only gain powerful strength, but also have the possibility of understanding some secrets about the Ten Thousand Worlds. For Duan Litang and his companions who were determined to explore the secrets of the blood covenant and improve their strength, this was undoubtedly a great opportunity.

  Lingxian Trial Tower stands on the back mountain of the academy. It is made of simple gray boulders. The tower is octagonal and reaches up to the sky, exuding a heavy and mysterious atmosphere. The tower is engraved with strange runes and ancient patterns. Under the sunlight, it flickers with a faint light, as if telling a long history. In front of the tower, many outer disciples have already gathered. They are whispering to each other, their eyes full of expectation and tension. Duan Litang, Su Xueli, Ling Xianer and Tang Xiaotang are also among them. Their eyes are firm and not affected by the surrounding noise at all.

  "I've heard the elders talk about this Lingxian Trial Tower. Each level corresponds to an emotional test, which is extremely difficult. But if you can pass it, the rewards will be beyond your imagination." Su Xueli said softly, with a hint of worry in her eyes as she looked at Duan Litang and others.

  "What are we afraid of? We've even made it through the Spirit Clan's Wanling Mountains, so why should we be afraid of this trial tower?" Tang Xiaotang waved his little fists, his face full of eagerness to try.

  Ling Xian'er nodded slightly, her hand unconsciously grasping the hilt of the ice sword at her waist: "No matter what happens, just go all out."

  Duan Litang took a deep breath, feeling the warmth from the blood-colored pendant on his chest, and said firmly: "Well, this may be a key step for us to improve our strength and get closer to the secret of the blood contract. Everyone, be careful."

  At this time, an elder in a golden robe slowly walked over. The elder had a dignified face and wise eyes. His appearance instantly quieted the disciples around him.

  “Dear disciples, the Lingxian Trial Tower opens once every ten years, and today is the opening day. Once you enter, you will face the test of the seven emotions. This is not only a test of your strength, but also a tempering of your state of mind. Remember, do not lose your original intention.” The elder’s voice was powerful and resounding in everyone’s ears.

  As the elder cast his spell, the door of the trial tower slowly opened, and an ancient and mysterious atmosphere came to the face. The disciples entered the tower in order. Duan Litang and the other three looked at each other and also stepped into the mysterious trial tower.

  Once they entered the tower, they were in a dim space, surrounded by a faint mist. In front of them, a narrow staircase wound upwards, leading to the unknown depths. Duan Litang walked in front, his eyes alert, always paying attention to the movements around him. Su Xueli followed closely behind, holding the Lingxian Sword tightly in her hand, the sword body trembling slightly, as if sensing the danger around her. Ling Xian'er and Tang Xiaotang walked side by side, Ling Xian'er's ice sword exuded a trace of coldness, and Tang Xiaotang's spirit butterfly arrow trembled slightly in the quiver, as if looking forward to the upcoming challenge.

  They walked up the stairs, and with every step they took, they could feel the pressure around them gradually increasing. Finally, they arrived at the first floor. The first floor was relatively open, and the walls were engraved with all kinds of hideous faces, which seemed to be telling of endless fear. Suddenly, a sinister laugh sounded, and an illusory figure appeared in front of everyone. The figure looked like an evil ghost, and it pounced on them with its fangs and claws bared.

  "Be careful, this is an illusion of fear." Duan Litang shouted, and the blood-colored wings behind him instantly spread out, and a powerful aura spread outward. Su Xueli waved the Lingxian Sword, and a golden sword energy slashed at the illusion; Ling Xian'er cast an ice spell, and an ice spike shot at the evil ghost; Tang Xiaotang also shot out the Spirit Butterfly Arrow, and the colorful light illuminated the entire space. However, the illusion was like a ghost, easily avoiding their attacks and continued to approach them.

  Duan Litang took a deep breath, concentrated his mind, and circulated his spiritual power. He found that the illusion seemed to change according to their inner fear. He tried to keep himself calm, no longer looking at the appearance of the illusion, but focusing on the movement trajectory of the illusion. Finally, he found the flaw of the illusion, and swung his blood-colored wings violently, and a strong airflow knocked the illusion away. As the illusion dissipated, the test of the first level was also declared over, and they continued to move towards the second level.

  The space on the second floor was filled with a strong atmosphere of anger. On the ground, magma was rolling, and the scorching heat was unbearable. From time to time, huge flaming rocks fell from the sky, hitting the ground and splashing hot magma. In this hot environment, everyone's emotions gradually became irritable.

  "Everyone, calm down and don't be swayed by anger." Su Xueli shouted loudly. She activated her magical power and formed a golden shield around everyone to resist the attacks of high temperature and flaming stones.

  Duan Litang, Ling Xian'er and Tang Xiaotang also used their spiritual power to resist the influence of the environment. However, as time went by, anger spread like weeds in their hearts. Duan Litang looked at the flaming stones falling around him, and a nameless anger surged in his heart. He wanted to rush up and destroy everything. Just when he was about to lose his mind, he suddenly felt the blood-colored pendant on his chest slightly warm, and a cool feeling spread throughout his body, making him sober instantly.

  "Everyone, concentrate. This is a test in the Trial Tower. We can't be controlled by our emotions." Duan Litang reminded everyone loudly. With his reminder, everyone gathered their minds and tried to stay calm. They cooperated with each other, cast their own spells, avoided the attack of the flaming stones, and walked towards the exit of the second floor. After a difficult journey, they finally passed the second floor successfully.

  The third level was a test of greed. As soon as they entered this level, they were stunned by the scene before them. The entire space was filled with all kinds of rare treasures, glittering spiritual crystals, magical weapons emitting powerful auras, precious elixirs. everything. These treasures emitted an alluring light, as if calling them.

  Tang Xiaotang's eyes lit up instantly, and she walked towards the pile of spirit crystals involuntarily: "Wow, so many treasures, we are rich."

  "Xiaotang, don't touch it! This is a test of greed." Su Xueli shouted hurriedly.

  The narrative has been illicitly obtained; should you discover it on Amazon, report the violation.

  However, Tang Xiaotang seemed to have been blinded by greed. She could not listen to Su Xueli's words and reached out to take the spirit crystal. Just as her hand was about to touch the spirit crystal, a black light flashed and the spirit crystal instantly turned into a pile of ashes. At the same time, Tang Xiaotang was also knocked away by a powerful force and fell to the ground.

  "Xiaotang!" Duan Litang, Ling Xian'er, and Su Xueli hurried over and helped Tang Xiaotang up. A trace of blood flowed from the corner of Tang Xiaotang's mouth, and her eyes were full of fear and regret: "I. How could I be like this?"

  "It's okay, Xiaotang, this is a trap in the Trial Tower. We can't be fooled by greed." Duan Litang comforted Tang Xiaotang.

  Everyone stood up, closed their eyes, stopped looking at the treasures around them, and walked towards the exit of the third floor with a firm will. Along the way, the temptation of treasures kept coming, but they always stuck to their original intentions and remained unmoved. Finally, they successfully passed the third floor.

  The fourth level is the "Realm of Love". When they stepped into this level, the scene in front of them changed instantly. Duan Litang found himself in a beautiful valley with blooming flowers and green grass, just like a fairyland on earth. In the center of the valley, there was an exquisite cottage. In front of the cottage, Su Xueli, Ling Xian'er and Tang Xiaotang were smiling and waving at him.

  Duan Litang felt warm in his heart and walked towards them involuntarily. When he approached, he found himself in three different parallel scenes. In the first scene, he and Su Xueli were dressed in gorgeous clothes, walking hand in hand in the clouds of the fairyland, and the surrounding fairies cast envious glances at them; in the second scene, he and Ling Xian'er were in the ice palace of the demon realm, the two of them leaned against each other, watching the snowflakes falling outside the window, with happy smiles on their faces; in the third scene, he and Tang Xiaotang were in the Spiritual Butterfly Valley of the Spirit Clan, chasing spirit butterflies together, and their laughter echoed throughout the valley.

  Duan Litang was immersed in this beautiful illusion, with a happy smile on his face. However, at this moment, an icy spike suddenly pierced through the illusion, and Ling Xian'er's cold voice rang in his ears: "Is the sugar in the illusion sweet?"

  Duan Litang suddenly came back to his senses. He looked at the shattered illusion in front of him, and his heart ached. He knew that this was a test of his love from the Trial Tower, and he couldn't indulge in the illusory beauty. He took a deep breath, looked at Ling Xian'er, and said firmly: "Whether it is an illusion or reality, you are extremely important to me. I will not get lost, I want to face everything with you."

  After saying this, he activated his spiritual power and broke the illusion around him. Su Xueli, Ling Xian'er and Tang Xiaotang also woke up from the illusion. They looked at Duan Litang with relief in their eyes. The four nodded to each other and continued to move towards the fifth floor.

  The fifth level is the "Evil Realm". This level is filled with all kinds of evil auras, and the power of darkness is surging around. On the ground, black vines grow wantonly, trying to entangle their footsteps; in the air, black fog permeates, making it difficult to see the road ahead. In this evil environment, malice gradually surges in everyone's hearts.

  "Everyone be careful, this is the erosion of evil thoughts." Duan Litang shouted loudly. He circulated his spiritual power to form a layer of blood-colored shield around him to resist the erosion of evil forces.

  Su Xueli, Ling Xianer and Tang Xiaotang also cast spells to resist the invasion of evil thoughts. However, as they went deeper, the erosion of evil thoughts became stronger and stronger. Duan Litang felt that there was a dark force surging in his heart, and he wanted to destroy everything and destroy everything. Just when he was about to be swallowed by evil thoughts, he suddenly remembered his life experience, the old temple keeper's instructions, and Su Xueli, Ling Xianer and Tang Xiaotang. He gritted his teeth and tried to resist the erosion of evil thoughts, silently saying in his heart: "I can't be swallowed by darkness, I must protect everything I cherish."

  With his persistence, the blood-colored pendant glowed again, dispelling the darkness around him and gradually calming his mind. He looked at Su Xueli, Ling Xianer and Tang Xiaotang beside him, who were also trying to resist the erosion of evil thoughts. Duan Litang shouted loudly: "Together, we can definitely defeat this evil thought." Hearing this, everyone supported each other and worked together to finally successfully pass the fifth floor.

  The sixth floor is the "realm of kindness". Different from the fifth floor, this floor is full of warmth and light. The soft light illuminates the entire space, and the air is filled with the fresh fragrance of flowers. In this beautiful environment, everyone's hearts are also full of kindness. However, this seemingly beautiful environment hides a deeper test.

  As they continued to move forward, they found an injured child lying on the ground in front of them, with a look of pain on his face. Seeing this, Tang Xiaotang immediately wanted to step forward to help him.

  "Xiaotang, be careful, there might be a trap." Su Xueli hurriedly grabbed Tang Xiaotang.

  Tang Xiaotang looked at Su Xueli with doubts in his eyes: "This child is so pitiful, how can we just watch him die?"

  Duan Litang and Ling Xian'er also stepped forward. They observed the child carefully and found that there was a faint fluctuation of magic power emanating from the child.

  "This child may be an illusion of the Trial Tower. We can't be fooled easily." Duan Litang said.

  Tang Xiaotang hesitated for a moment. She felt sorry for the child's pain. But she knew Duan Litang was right. She took a deep breath and tried to control her impulse to save the child. However, the child's cry became louder and louder, as if calling for their help. Tang Xiaotang was very confused and her eyes were full of struggle.

  At this moment, the child suddenly stood up, with a strange light flashing in his eyes: "You hypocritical people, you keep talking about kindness, but you turn a blind eye to my pain." After saying that, his body instantly swelled up and turned into a huge monster, rushing towards everyone.

  "It's a trap indeed." Duan Litang snorted coldly, and the blood-colored wings behind him spread out. He waved the wings and rushed towards the monster. Su Xueli, Ling Xian'er and Tang Xiaotang also cast spells and fought fiercely with the monster. After a hard fight, they finally defeated the monster and passed the sixth floor.

  Finally, they arrived at the seventh floor. The space on the seventh floor was filled with a mysterious atmosphere. In the center of the space, an old man in a white robe was standing there quietly, his eyes were deep, as if he could see through everything. The old man's eyes fell on Duan Litang, especially the blood-red pendant on his chest, and a trace of excitement flashed in the old man's eyes.

  "After three hundred years, I finally waited for a blood contract host." The old man muttered to himself.

  Duan Litang and others were shocked when they heard this. They walked forward and saluted the old man respectfully.

  "Senior, are you the tower keeper? Why do you say that after three hundred years, you have finally waited for the blood contract host?" Duan Litang asked.

  The old man nodded slightly: "I am the first generation of tower keeper of Lingxian Academy, and I have been guarding here for hundreds of years. I know a thing or two about the blood covenant. In the past, after the ancient god war, the blood covenant was divided into nine parts and scattered all over the world. The blood-colored pendant on you is one of the key fragments of the blood covenant. Three hundred years ago, the host of the blood covenant suddenly disappeared, and the secret of the blood covenant was buried. Now, you appear with the pendant, which must be the arrangement of fate."

  "Senior, how can we awaken the power of blood covenant and seal the chaos?" Su Xueli asked anxiously.

  The old man looked at the four of them and said slowly: "To awaken the power of the blood contract, you need to gather the purest blood of the three realms, use your heart as a guide, and hold a ceremony on the top of the ancient sacred mountain. Along the way, you will face countless difficulties and obstacles, but as long as you work together and stick to your original intentions, you will succeed."

  "Thank you for the information, senior." Duan Litang and others bowed again.

  The old man waved his hand slightly: "Go ahead, I hope you can shoulder the responsibility of protecting the world."

  Duan Litang and his three companions turned around and walked towards the exit of the Trial Tower. They knew that this was just the beginning of their adventure and that there would be more challenges waiting for them in the future. But they were not afraid, because they had firm beliefs and each other's company. They would join hands in embarking on this blood covenant road full of unknowns and challenges, and move forward courageously for the peace of the world and for each other's fate.
