When Yun Yi opened his eyes again, he found that he had walked out of the illusion array and came to an unfamiliar room.

In the center of the room stood an ancient book. Yun Yi approached and saw that the title was The Secret of Formation. He was secretly delighted. Could this be the legendary secret book of formation?

Yun Yi couldn't wait to open the book. The text and pictures inside were densely packed, but with his extraordinary wisdom and understanding, he slowly comprehended the mysteries inside.

As time went by, Yun Yi immersed himself in the world of the book, and his understanding of the battle formations became deeper and deeper. After an unknown amount of time, he finally finished reading the entire book.

However, when Yun Yi stepped out of the room, he found himself in a lush forest. Yun Yi couldn't help but wonder, what kind of formation was this?

Yun Yi searched the forest for an exit, but to no avail. Just as he was at his wit's end, he suddenly heard the melodious chirping of birds. He followed the sound and suddenly saw a towering ancient tree. Its trunk was covered in strange symbols, like the patterns of some kind of formation.

Yun Yi approached the ancient tree curiously, trying to decipher the meaning of the symbols on it. However, at this moment, the ancient tree suddenly emitted a dazzling light, enveloping him. After the light disappeared, Yun Yi found himself in a mysterious space.

The space was filled with rich spiritual energy. Numerous stone platforms stood around it, each holding a treasure. Yun Yi was overjoyed, suspecting this might be the core of the formation. He excitedly walked towards the platforms, carefully examining the treasures.

Yun Yi's gaze fell upon a stone platform gleaming with purple light. Atop it rested a precious sword. He reached out and grasped the hilt, a surge of powerful force instantly flooding into his body. The blade shone with a strange light, as if possessing endless potential.

Yun Yi wielded the sword, feeling its sharpness and agility. A surge of confidence surged in his heart, believing that this sword would become his effective partner in his battle against the demons.

At this moment, a slightly teasing voice sounded in the space: "Congratulations on finding the treasure included in the formation, but whether you can take it out depends on your next performance."

Yun Yi wielded the sword with a light touch, his blade creating a series of dazzling sword flowers in the air. His sword moves were as natural and smooth as flowing water, and he couldn't help but sigh: This sword is a perfect match for him, as if it was made specifically for him.

At this moment, Yun Yi's bright eyes were filled with high spirits, and his entire body exuded an air of confidence. Facing the upcoming unknown challenge, he was not afraid. He held his head high and chest puffed out, and responded in a loud voice: "Yun Yi is ready, please begin!"

The moment he finished speaking, the surrounding space suddenly twisted violently. A powerful force enveloped Yun Yi, making it impossible for him to break free. In the blink of an eye, he disappeared from the spot where he stood, swept into an unknown place.

When Yun Yi opened his eyes again, he was shocked to find himself on a steep, precipitous rock face that reached high into the clouds. He carefully lowered his head and saw that the area where he was standing was only 20 to 30 centimeters wide. If he was not careful, he could fall into the abyss.

Even more terrifying was the countless gigantic snakes swarming densely below. These snakes were a dazzling array of colors, some emerald green like jade, some fiery red, and still others a mysterious purple-black hue...

They all spit out their long tongues and make a hissing sound, as if to warn Yun Yi - as long as he falls off the cliff, they will swallow him up without hesitation.

The scene before him was too horrifying and terrifying. Yun Yi calmed himself down and moved cautiously, trying to find a safe route.

However, the big snakes seemed to have sensed his intention and began to wriggle their bodies towards him. Yun Yi had to brandish his sword and engage in a thrilling battle with them.

Yun Yi was gradually losing ground due to the sheer number of snakes. Just as he was struggling to cope, he suddenly noticed some strange protrusions on the stone wall. An idea struck him: he decided to use these protrusions to escape his predicament.

Yun Yi leaped with all his might, stepped onto a bump, and then, using the rebound force, leaped onto another bump. In this way, he leaped between the rock walls, gradually moving away from the dangerous snakes. Finally, he successfully reached the other side and left this thrilling place.

As he walked, Yun Yi felt that the surrounding environment was becoming increasingly hot and unbearable. He looked up and was shocked to find that there were ten huge and scorching suns hanging high in the sky!

The dazzling light poured down relentlessly like an irresistible heat wave, scorching the vast desert. The earth seemed unable to withstand the intense heat; it began to glow slightly, as if it would burst into flames at any moment.

Yun Yi dragged his heavy feet with difficulty, each step forward feeling like he was carrying a heavy burden. Sweat had already soaked his clothes, but in the extremely dry air, the moisture quickly evaporated, making him feel even more thirsty. His lips, chapped from prolonged dehydration, even bled. His throat felt as if it were burning in agony, and swallowing saliva became a luxury.

Yun Yi stared blankly at the endless sea of ​​sand before him, a wave of despair welling up in his heart. Lost in this desolate and silent desert, he felt lost and couldn't find a way out. However, just as Yun Yi was about to reach despair, a glimpse of green suddenly caught his eye—a lush oasis appeared not far ahead!
