Su Muxi stood in the center of the formation, surrounded by dense runes and lines, which sparkled mysteriously under the moonlight.

Su Muxi first checked every part of the formation to make sure there were no omissions or errors.

She knew that even the smallest mistake could lead to the failure of the entire formation.

Then, she began to slowly inject her own spiritual power into the formation.

According to the formation master's research results and his own analysis, he activated the key points of the formation one by one.

Spiritual power flowed along the lines of the formation like running water, lighting up one rune after another.

As spiritual power continued to be injected, the formation began to emit a low humming sound, as if an ancient machine was slowly starting up.

Su Muxi felt an unprecedented connection, as if a special resonance had been established between her and the formation.

Su Muxi closed her eyes and began to adjust the frequency of the formation based on her intuition and understanding of the formation.

She could feel every vibration and every change of the formation conveying information to her.

Suddenly, Su Muxi felt a powerful energy surging out from the formation, as if it was going to swallow her up.

She clenched her teeth tightly, trying to resist the force.

Sweat dripped from her forehead, but her gaze remained firm.

As time passed, Su Muxi's body gradually adapted to the energy fluctuations in the formation.

She began to try to communicate with the formation and feel the mystery within it.

When all the runes were lit up and all the lines were filled with spiritual power, Su Muxi opened her eyes.

She clasped her hands together and uttered the final spell.

The air in the center of the formation began to twist, forming a vortex of light.

The vortex gradually expanded and formed a portal.

Su Muxi could feel the breath from the other side of the portal. That was her familiar world, her home.

She knew that as long as she crossed this portal, she would be able to return to the place she had longed for day and night.

Before stepping through the door, Su Muxi looked back at the courtyard where she had lived for three years, where her friends and memories were.

But she knew she had to go back, for herself and for those who were waiting for her.

Su Muxi took a firm step and walked into the vortex of light.

As her figure disappeared into the portal, the light of the formation gradually dissipated, leaving only the silent night.

When Su Muxi was able to see the scene clearly, she found herself in a familiar place - the cave she had entered with the special operations team.

However, the cave is no longer as dark as it once was.

Instead, it was brightly lit, with bright lights hanging on the walls of the cave, illuminating the entire space.

There are desks of various sizes placed in the cave, and more than a dozen figures are concentrating on studying something.

Su Muxi suppressed the joy that surged in her heart, coughed calmly, then put her hands behind her back and put on a majestic posture.

Hearing the noise, more than a dozen people raised their heads at the same time, their eyes falling on the graceful girl in front of the formation that they had been studying for three years without any progress.

Their eyes widened, expressions of astonishment on their faces, obviously confused and puzzled by the sudden appearance of this strange girl.

Some people even stepped forward cautiously to ask, "Who are you? How did you get in?"

Just then, a cry of surprise broke the silence.

"Ah, it's Su Muxi, Su Muxi is back."

Song Qi shouted excitedly, rushed out from behind the crowd and ran straight to Su Muxi.

She stared at Su Muxi in disbelief, then turned her head to look at the formation behind her, her eyes flashing with excitement.

Suddenly, she rushed forward and hugged Su Muxi tightly.

"Su Muxi, it's really you. Great! You're finally back."

Song Qi shouted excitedly, and his voice echoed in the cave, as if to wake up the entire cave.

Immediately afterwards, the other people in the cave also started clapping as if they had just woken up from a dream.

"It's been three years, and Master Su actually came back on his own."

Someone said in surprise.

"I didn't expect that after three years of research without any results, Master Su would appear before us. It's truly amazing."

another added excitedly.

Su Muxi was a little confused by Song Qi's enthusiasm and didn't know how to respond for a moment.

She patted Song Qi's back gently and said with a smile, "Captain Song, put me down first."

Hearing this, Song Qi realized that he was still holding Su Muxi tightly. He quickly loosened his hands and carefully put her on the ground.

"Su Muxi, you're finally back. I need to tell Old Niu the good news right away. He's been so worried about you all these years that his hair has turned gray."

As Song Qi spoke, he couldn't wait to pull Su Muxi's hand and walked out of the cave.

Along the way, Song Qi kept telling Su Muxi about their search and waiting over the past three years, as if he wanted to pour out all his bitterness.

"And me, Su Muxi, look, I've been in this deep forest for three whole years just to find you."

Song Qi pointed at himself, his face full of fatigue and vicissitudes.

"In the past three years, not only Mr. Niu, but even I have almost turned gray with worry."

Song Qi shook his head helplessly, with a hint of worry in his eyes.

Song Qi brought Su Muxi all the way out of the cave. Looking at the familiar yet unfamiliar scenery in front of him, Su Muxi felt a lot of emotions in his heart.

The scene outside the cave has changed a lot compared to three years ago.

In a place that was once lush with vegetation, although the big trees still stand, the surrounding weeds have been cleared away.

Five or six wooden houses of different sizes were built around the cave, making it look like a small residence.

However, apart from these changes, everything else seems to have remained unchanged.

Su Muxi could feel that Song Qi and his team had put in a lot of effort in order not to destroy the ecosystem in this forest, and their living conditions were indeed quite difficult.

When Song Qi told Niu Bo the news that Su Muxi had returned, Niu Bo immediately sent someone to pick up Su Muxi and take him back to Beijing.

On the way back to Beijing, Song Qi told Su Muxi what had happened in the three years since she disappeared.

At that time, Su Muxi tried to break the formation, but suddenly disappeared.

Jiao Peng immediately asked the formation master to try again, but no matter what, he could not restart the formation.

So he reported the situation here to Niu Bo.

Since Su Muxi was a key training target of the special operations team, her disappearance attracted great attention from higher authorities.

Soon, the top formation master was sent to study this formation.

However, this formation was extremely sophisticated and required extremely high spiritual power, so no one could solve it for a while.

Therefore, the special operations team sent Song Qi to stay here permanently and assist the formation master in his work.
