The genius who counterattacked the mainland

During the peaceful days, Xu Tiancai's reputation within the coalition was at its peak. However, he did not become complacent and continued to immerse himself in cultivation and the exploration of magical knowledge every day.

One day, Xu Tiancai received a mysterious letter. Made of a strange material, seemingly made from an ancient animal hide, the letter's calligraphy was intricate and vibrant, emitting a faint magical aura. The letter invited Xu Tiancai to a mysterious place called the "Lost Realm," said to hold secrets about the world's fundamental power and hold crucial significance for his growth and future. However, the letter didn't reveal the identity of the inviter, raising concerns in Xu Tiancai's mind.

Xu Tiancai took the letter to Zhang Jie and Mira to discuss it. Zhang Jie frowned, pondered for a moment, and said, "This is far too strange. It might be a trap. But if what the letter says is true, this is indeed a rare opportunity. It may allow you to achieve a greater breakthrough in your strength, and it will also greatly benefit our coalition forces in combating future unknown threats." Mira said with some concern, "I have a feeling there's some danger hidden behind this that we're unaware of. But Xu Tiancai, your decision is crucial. No matter what you choose, we will support you."

Xu Tiancai fell into deep thought, his inner desire for power and curiosity about the unknown constantly playing tricks on him. Finally, he decided to take a risk. He knew that only by constantly improving his own strength could he better protect the world. Before setting off, he made thorough preparations, bringing along some necessary magical props and supplies.

Following the instructions in the letter, Xu Tiancai arrived at a remote valley. A thick fog filled the valley, making it difficult to see the path ahead. He advanced cautiously when, suddenly, a flash of light appeared, revealing a mysterious teleportation array. Xu Tiancai took a deep breath and resolutely stepped into the array.

After a dizzy spell, Xu Tiancai arrived in a strange world. The sky was as blue as a gem, the ground was covered in green grass, and the air was filled with a strong magical aura. But he also keenly sensed that this seemingly beautiful place concealed many unknown dangers.

Not far away, an ancient castle stood atop a hill. Its architecture was unique, its walls engraved with mysterious runes and patterns, as if telling of a long history. As Xu Tiancai walked toward the castle, he encountered many strange creatures along the way, some radiating gentle auras, while others exuded intense aggression.

When he arrived at the castle gate, it slowly opened automatically. A voice rang in his ear: "Welcome, Xu Tiancai. You are the chosen one. Here are the answers you seek." Xu Tiancai walked into the castle cautiously. The hall was empty, with only the torches on the wall flickering eerily.

He continued deeper into the castle, and in one room, he discovered a book emanating powerful magic. The words on the book were new to him, but the moment he touched it, a flood of information flooded his mind. It turned out that this "Lost Realm" was an ancient magical trial ground, where countless powerful warriors once explored and grew. He was invited here because his unique talent and potential were recognized by the guardians.

However, gaining this power is no easy task. He needs to pass a series of trials and challenge his own limits before he can truly comprehend the secrets of the world's original power. Undeterred, Xu Tiancai decided to rise to the challenge.

The first trial involved traversing an enchanted forest, filled with traps and powerful creatures. Xu Tiancai carefully employed his magical skills, dodging trap after trap. When attacked by creatures, he remained undaunted and engaged in fierce combat. He skillfully harnessed the power of magical elements, fusing fire, water, earth, and wind to unleash a powerful attack and gradually defeat the creatures.

While traveling through the forest, Xu Tiancai discovered some hidden clues and magic runes. By deciphering these runes, he learned some new magic techniques and combat strategies, which further enhanced his strength.

After an arduous trek, Xu Tiancai finally emerged from the enchanted forest and arrived at the foot of a high mountain. The second test was to climb this mountain. The path was steep and treacherous, and was also affected by powerful magical currents, making it difficult to maintain a steady footing. With unwavering perseverance and exceptional physical fitness, Xu Tiancai climbed step by step. As he climbed, he constantly adjusted his breathing and the use of his magical energy to cope with various emergencies.

As he neared the summit, a massive rock monster suddenly appeared. Composed entirely of solid rock and possessing immense strength, it continuously hurled rocks at Xu Tiancai, attempting to halt his advance. Xu Tiancai calmly observed the monster's attacks, noting that while its movements were slow, its attacks were powerful. He decided to use his agility and the ranged attack capabilities of his magic to counter it.

Xu Tiancai unleashed a powerful magical attack. Rays of light flew towards the rock monster, leaving cracks on its body. The monster roared angrily and charged at Xu Tiancai. Xu Tiancai skillfully dodged the monster's attacks while constantly searching for its weaknesses. Finally, he discovered the monster's core, hidden in its chest, the source of its power.

Xu Tiancai concentrated all his strength and unleashed a powerful magical blast, striking the monster directly in the core. With a resounding bang, the rock monster collapsed, turning into a pile of rubble. Xu Tiancai successfully defeated the monster and continued to advance towards the top of the mountain.

After unremitting efforts, Xu Tiancai finally reached the top of the mountain. There was an ancient altar on the top of the mountain, and on the altar was a crystal ball. The crystal ball contained powerful magical power, which seemed to be the goal of his trial.

Xu Tiancai stepped forward and carefully picked up the crystal ball. Instantly, a powerful force surged into him, and his body began to transform. The magical elements around him swirled wildly. He felt a breakthrough in his magical realm, and his understanding of the fundamental power of the world deepened.

However, just as he was immersed in the increase of power, he suddenly felt a dark breath approaching. He opened his eyes and found a black cloud in the sky, and faintly heard bursts of evil laughter from the dark cloud.

Xu Tiancai realized that his trial was not over yet, and the real challenge had just begun...
