Within an inn in Hanyun City.

Lu Yu sat in a room and finished setting up the illusion array.

After returning to the original inn, Lu Yu returned to his previous place and returned to another inn.

From the outside, one wouldn't be able to see the structure at all.

Aside from informing Luo Ming, Lu Yu didn't tell anyone else.

After all, someone still planned to assassinate him, so there was no need for Lu Yu to take the risk.

"The last black-clad figure to appear has a trace of righteousness in him. I'm afraid that it was sent by that White Deer Institute's formation master."

"As for those people who came first, they said that I took something that I shouldn't have. Could it be that they also know about the Yin World Stones?"

Lu Yu thought about it for a moment, then stopped thinking about it.

They, even though their current cultivation was higher than Lu Yu's.

However, in Lu Yu's eyes, these people were still ants.

"Now that I have this Yin World Stone, I guess the small world of the Beitang Heavenly Sect can be repaired." Lu Yu immediately took out his storage bag.

Sweeping his gaze across the pile of spirit stones, Lu Yu used his Spiritual Sense and took out the Yin World Stones from his storage bag.

"Yin energy, gather to your heart and break!"

Lu Yu chanted an incantation and his finger landed on the black Yin Qi stone.

Suddenly, cracks could be seen on the surface of the Yin Qi stone.

As the cracks gradually began to spread, they soon extended over the entire surface of the rock.

Ka-cha! *

A small crack appeared on the stone, and a strand of Qi was silently emitted.

A strand of yin aura appeared in Lu Yu's hand. He gently grabbed it with his hand.

"This is indeed a pure Yin World Stone. Luckily, the people here do not know what is good for them, otherwise, it would take a lot of effort."

Lu Yu put the strand of Yin Qi directly into the small world of the Beitang Heavenly Sect.

Instantly, the entire small world began to tremble.

It was like a person who had been thirsty for a long time suddenly drinking water.

The strong gales and dense fog that had shrouded the entire surroundings of the Big Dipper Mountain had gradually scattered.

It was still hazy in the sky of this small world, but the fog had already parted.

In the medicine fields of the Beitang Heavenly Sect, a faint spiritual energy was gradually recovering.

In the air, Yin Qi and Yang Qi began to converge and eventually formed a mysterious taiji diagram, slowly rotating.

Following the rotation of the taiji diagram, everything in the Northern Dipper Sect started to be filled with vitality.

Rumble rumble rumble!

Under the guidance of Lu Yu's Spiritual Sense, the countless stones within the mountain started to fill up the ruins of the Beitang Heavenly Sect.

He saw that the broken ruins were slowly recovering.

"The space cracks have already dissipated, but the laws here are still broken. I'm afraid that it will take some time for them to recover." Lu Yu muttered to himself for a moment and arrived at the cultivation tower with a single step.

Reaching this point, Lu Yu immediately felt a burst of abundant spiritual energy, contained within.

"There is actually a tiny bit of the Space and Time Laws contained within, but it's incomplete." Lu Yu looked around, and immediately sensed the situation.

"That's fine too, this Space-Time Law can save me a lot of time. If I train here for one day, I'm afraid it will be enough for the outside world to cultivate for three days! " A light flashed in Lu Yu's eyes as he sat cross-legged in the cultivation tower.

Immediately, waves of spiritual energy rushed into Lu Yu's body.

"200 million spirit stones is enough for me to break through!" Lu Yu immediately opened the storage bag.

Immediately, a large pile of spirit stones scattered in front of Lu Yu, emitting bursts of spiritual power.

Lu Yu opened his mouth and countless spirit stones immediately shattered, forming a powerful spiritual energy that rushed into Lu Yu's internal organs.
