Stepping inside, one perceives the aura of heaven and earth that is so rich that it is maddening. The concentration of aura in the outer world is more than ten times higher. And it contains a special energy.

It can enhance the power of the body, the power of the soul, and even the understanding of students......

A place of cultivation of the great power of the Tribulation Period, Rao was destroyed and nearly ninety percent of it, but it still showed an extraordinary.

The efficiency of cultivating here for one day is equivalent to Mu Chen's cultivation in the Golden Spirit Cave of the Spirit Master Academy, and one month of cultivation, or even higher.

Standing in the white jade square to watch, the building complex is intact, the treasure light lingers, a look is the blessed land of the fairy family, let people shine in front of their eyes, and they can't wait to go inside to investigate.

But when you really enter the scene in front of you, it is completely different, and it is all remnants of bricks and rubble, exuding a faint treasure light, and the damaged fifth-order refining materials, Mu Chen, was slightly shocked.

So many bricks and buildings, made of fifth-order materials, the power of the Tribulation Period, and the terrifying value?

Moreover, fifth-order refining materials are the most common existence, and sixth-order and seventh-order refining materials are turned into rubble, which can be seen everywhere.

Mu Chen's heart was amazed, such a precious material, why didn't the new students collect it, and let it sit in place, emitting a precious light.

Picking up a seventh-order beast head, Mu Chen carefully examined it, and then put it down with a sigh and regret.

The materials of the seventh order can't withstand the baptism of time after all. Ten thousand years of time have already corroded everything inside it and turned it into a fragment.

But because of the excessive abundance of aura, the appearance remained the same, shining with a brilliant treasure.

The refining materials are waste, but the herbs that survive among the rubble of the bricks are full of medicinal properties and are old. Each plant has reached the level of 10,000 years. Each plant is worth a lot of money.

This is planted for the spirituality of space debris, so as not to waste such a rich aura of heaven and earth.

Three different 10,000-year-old spirit grasses were scattered in different directions, thriving, and the wood dust picked them one by one and sent them into the Sun and Moon Cave.

Looking at the surrounding environment, there was no trace of monks, demon beasts, or evil demons, and there was a dead silence. Soul power swept through and found no danger, and Wood Dust walked forward, exploring the complex, searching for herbs and valuable items.

Mu Chen can vaguely perceive the breath of Niu Er, Lingyun and others. But if you want to pull everyone into a state of sharing, you can't get it, as if there is a mysterious force in the dark.

Walking 100 meters, Mu Chen's knowledge of the sea flashed a bold idea: Can the Sun and Moon Cave be opened? Accelerate the absorption of external aura. Let the aura in the Sun Moon Cave reach the same level as this place in a short time.

The Sun Moon Cave can slowly absorb the external aura and supplement the richness of the internal aura. But it's too slow. It will take 10 years, maybe to get to where we are now.

Once this idea emerges, it is difficult to suppress, and Mu Chen immediately crosses his knees and arranges the next formation to protect himself and think about the possibility of success.

"First of all, a terrifying Spirit Gathering Array is needed, and it is placed at the entrance to the Cave ......."

A stick of incense? Mu Chen's mouth opened his eyes with a smile on his mouth, and after some careful calculation, the probability of success reached eighty percent.

Wood dust collects materials and begins refining......

Nine hours passed, and Mu Chen successfully refined a huge array disk of the fourth order, three thousand array flags.

Mu Chen's idea was very simple, turning the Sun and Moon Cave into a huge spirit gathering array.

The formation flag is integrated into the node of the sun and moon cave sky, and the array plate is coordinated as a whole, and when everything is ready, Mu Chen opens this formation.

For a while, the Sun and Moon Cave turned into a black hole, frantically swallowing the aura of heaven and earth.

The aura tide around the body of the wood dust condensed and transformed into a vortex of spiritual energy, and some of the refining materials turned into powder and disappeared under the impact of this powerful force.

The whole area was a mess, and it was much cleaner.

In just a stick of incense, Mu Chen could clearly feel that the quality of the aura around his body had decreased, and the concentration of aura in the cave had nearly doubled.

The space debris sensed the situation and tried to stop the wood dust, but in the end, it did not appear. Everything that Muchen does is within the scope of the rules.

After a night's effort, the concentration of spiritual energy in the entire building complex dropped by one percent, and the Sun Moon Cave Heaven could no longer carry more spiritual energy, reaching the full value, and Mu Chen reluctantly closed the Spirit Gathering Array.

The aura around the wood dust body is gone, and the aura in the distance is slowly replenished.

Stretch your muscles, exhale a breath of turbidity, and continue to explore this place after a day of hard work.

Speaking of which, what is the content of the third assessment? What exactly is the spirituality of space debris?

It wasn't just Mu Chen who had this doubt, but the students of the Six Dao Academy, the Demon Beasts, and the Sea of Consciousness who had entered the complex were all so suspicious.

Spiritually sent into the complex by space debris, i.e., regardless of it, without any guidance.

Helplessly, the students, and the demon beasts could only rely on themselves to investigate the surrounding situation, and complete this task in their own way, figuring out the spiritual intentions of the space debris.

Sure: No danger......

Confirmed: Ruins all around......

OK: Herbs are extremely numerous......

The students, the monsters, felt as if they were in a dream.

The wood dust spiritual sense swept all around, and all the buildings were reduced to ruins, and there was no place left intact.

Viewed from the White Jade Square, the building complex does not seem to be huge, occupying a radius of thousands of miles. But now, in the midst of it, covered by wood dust and spiritual consciousness, it is thousands of miles, but all of them are in ruins, and there is not a single intact building.

As for the area of the entire complex, Mu Chen doesn't know, but it is much larger than his Sun Moon Cave. Could it be the use of space power? A concept flashed in Mu Chen's heart.

Teleporting by himself, collecting medicinal herbs, and collecting materials, he is very busy. Every moment, Muchen's net worth is growing.

After flying for an hour, Mu Chen saw a building that was eighty or ninety percent intact, like a lonely plum blossom, opening alone on a cold winter day.

The building is a wooden and stone structure pavilion, refined from sixth-order materials, and is divided into three floors, but the top floor is destroyed, and you can faintly see the collapsed erections and spiritual tablets in it.

The white jade plaque, broken into three or four petals, fell to the ground, the pen walked the dragon snake carved with a few words, although after thousands of years, but can still perceive the spirit contained in it.

"The way of refining. ”

Mu Chen recognized these four words, and his heart was overjoyed, and he raised his feet and stepped into it.

Fang Wen's great power is the best thing in refining, I don't know if it contains the powerful refining experience, and if he can get it, maybe he can help himself to comprehend the art of empowering spirits and successfully promote to a fifth-order refiner.

Creaked, the wooden door screaked softly, and wood dust entered it.
