After exiting the Xuan Stone space, Li Sheng's consciousness rose, and the entire sect came into view. This time, the area of the sect had not expanded, and it seemed unchanged at first glance. However, upon closer inspection, he noticed the ground had become more fertile, and the vitality emitted by the trees and flowers was significantly more abundant. Additionally, all the buildings within the sect appeared to have been reinforced, giving a sense of ancient weight.

After a while, a notification sound came through.

**[The Guardian Grand Array has been upgraded.]**

Li Sheng opened the interface, and with a slight thought, a prompt appeared.

**[Do you wish to consume one thousand sect points to increase the formation's level?]**

Seeing this, he was taken aback. "A fourth-tier Guardian Grand Array can subdue Master-level experts and surround Grand Masters. I wonder if that's true..." Li Sheng mused, calling for Tuan Tuan.

"Chirp, chirp..." A small girl wearing a golden dress, about the size of a palm, appeared, exuding a fresh scent of grass and wood.

"Tuan Tuan?" Li Sheng exclaimed, curiously examining the little creature in his hand; her touch was cool and real.

"Chirp, chirp..." Once the little one transformed into human form, she seemed very ticklish and forcefully pried Li Sheng's thumb away before flying off.

"So you suddenly felt sleepy and woke up like this, feeling much stronger?"

"Chirp!"

Li Sheng smiled helplessly, feeling a twinge of envy at the little one's transformation. How wonderful it would be if he could use sect points to enhance his own cultivation.

"Tuan Tuan, show me your strength now." Li Sheng's eyes sparkled with anticipation. A Grand Master had comprehended the true essence of martial arts, forming a law body, and was terrifyingly powerful. Since the fourth-tier formation was said to be able to subdue Masters, it surely had remarkable capabilities. With Tuan Tuan, the formation spirit, it might even pose a lethal threat to Grand Masters.

At Li Sheng's words, Tuan Tuan tilted her head, sucking her finger, her large, lively eyes darting around.

"Chirp!"

With a wave of her little hand, the entire world suddenly dimmed, and a terrifying murderous intent erupted. As time flowed, this killing intent grew stronger, even causing a sharp pain to rise on Li Sheng's skin.

Such a strong disturbance naturally attracted the attention of many disciples in the sect, who emerged from their cultivation areas to gather around.

"Senior Brother, has Tuan Tuan transformed?" Bai Ye, dressed in a white long dress, looked on in surprise.

"Junior Sister, you're here." Li Sheng nodded, "The Guardian Grand Array has been upgraded, and Tuan Tuan, as the formation spirit, has also changed."

"The Guardian Grand Array has upgraded? It was already third-tier before; now it's reached"could it be fourth-tier?" Liu Hongying, eavesdropping nearby, exclaimed.

The tale has been taken without authorization; if you see it on Amazon, report the incident.

"Yes." Li Sheng replied, glancing toward the horizon.

"A fourth-tier Guardian Grand Array is said to be able to surround Grand Masters; there are only eleven Grand Masters in the entire world. That's incredible!" Tie Zhu, now at the seventh rank of bone refining, was informed enough about the cultivation world to react in astonishment.

"It's not the formation that's strong; it's the Sect Master who's remarkable." Chen Xixi, her beautiful eyes sparkling with admiration, gazed at Li Sheng.

The other disciples also showed expressions of joy, visibly excited.

Li Sheng paid no mind to their flattery. At this moment, Tuan Tuan's delicate face was filled with seriousness as she chirped continuously.

With Tuan Tuan's manipulation, the surroundings of the Qing Ling Sect transformed drastically. To the east, yellow smoke billowed, with lava bubbling and rolling, as if something were stirring beneath. To the west, a sky filled with red clouds appeared tranquil; Li Sheng threw a damaged fifth-tier divine weapon into it, and it was instantly reduced to ashes. To the south, a small purple mountain loomed larger as Li Sheng looked up, feeling increasingly insignificant until he shifted his gaze, returning everything to normal. To the north, a murky river of quicksand emerged, filled with countless whirlpools, evoking a strong sense of danger within Li Sheng.

As the terrain shifted, a massive light curtain formed in the center, resembling an inverted bagua (I Ching diagram).

"Chirp, chirp!!!" Tuan Tuan placed her hands on her hips, looking proudly at Li Sheng, her little face displaying an air of achievement.

"Very good, very good!" Seeing this display of power, Li Sheng finally felt relieved. The ability to alter the environment and influence the heavens through formations was certainly not inferior to the law bodies of Grand Masters.

Liu Hongying touched the edge of the bagua formation, feeling its icy touch like jade, and curiously asked, "Tuan Tuan, what is this formation for?"

"Chirp, chirp..."

"The central place... can control the surrounding formations and provide defense."

Li Sheng nodded inwardly, then opened the panel, directing his thoughts to the alchemy room.

**[Do you wish to consume twenty sect points to enhance the Spirit Wood Cauldron's spiritual essence?]**

"Enhance!"

He silently chanted, then dismissed the other disciples, turning to Bai Ye. "Junior Sister, the sect is about to face a great calamity in the coming days; ensure all disciples' families are brought into the sect."

"Calamity? Could it be those demon nests?" Bai Ye's fair face tightened, a hint of worry in her eyes.

"Exactly. But there's no need to worry; with the Guardian Grand Array upgraded, we can withstand even despair-level monsters," Li Sheng reassured her.

"Understood, Senior Brother. I will arrange it right away." Bai Ye nodded and turned to leave.

Retrieving his gaze, Li Sheng then tried to focus his thoughts on the Guardian Spiritual Beast.

**[Do you wish to spend one hundred sect points to shorten the juvenile period of the Titan Turtle?]**

Li Sheng raised an eyebrow in surprise, as there was no "+" sign at the back of the Guardian Spiritual Beast section. He was merely trying it out, but unexpectedly found a pleasant surprise.

"However, this cost seems a bit too high..." Although it was just to shorten the juvenile period, not a direct upgrade, he hesitated.

He glanced over the sect's other facilities; the spiritual pool and transmission hall were adequate, so there was no immediate need for upgrades. The Guardian Grand Array and spiritual vein still needed significant improvements.

For now, he could either upgrade the alchemy room or the training ground. "Anyway, we have plenty of sect points now; using a hundred will still leave me with one hundred thirty-five..."

"Yes!" Li Sheng silently agreed. Suddenly, the half-person-high Titan Turtle by the spiritual pool awoke from its slumber, its golden-orange eyes filled with shock.

A massive flow of earthy energy surged from deep within the earth, drilling into its body. The Titan Turtle let out an excited roar as it expanded hundreds of times, opening its giant mouth to frantically absorb the earth's essence.

Previously, it had simply been lying there, not sleeping, but using its affinity for earth to sense the earth's veins and capture the earth's essence. Normally, it could capture seven or eight strands in a day, and it would take at least several hundred years to transform into the mature stage.

But now, with the earthy essence flowing before it like a river, it could devour at will. Feeling the burgeoning energy within, the Titan Turtle couldn't help but let out a triumphant roar.

Li Sheng nodded with satisfaction; due to their bond, he could sense the Titan Turtle's thoughts.
