Mother is a tree, my mother has been cultivating immortality for eighty years and is invincible

Previously, through the conversations of other demons, Davis knew that the Grant Demon God had ruled the 1,412 layers of planes for hundreds of millions of years.

During these long years, he must have accumulated endless wealth by virtue of the power of the ruler of the plane.

And these riches should have been stored by him in the treasure house below the palace.

This treasure house, like the cultivation place of the Grant Demon God, was wrapped in layers of magic arrays.

Outside the formation, there are some demons guarding with fairly good strength.

One of the most powerful guardian demons, the strength even reached the upper gods.

This is the overlord-like existence of other abyssal planes, but here it is only worthy of the Grant Demon God to guard the door.

I have to say that the Supreme God is indeed quite a cow, far stronger than the several main gods that Davis has seen before.

However, no matter how many layers of magic arrays are wrapped outside this treasure house, and no matter how strong the strength of the gods guarding the treasure house is.

Davis's figure flashed, and he directly passed through the layers of protection and appeared in the treasure house.

As for the guards outside the treasure house, of course, they did not notice it in the slightest.

This treasure trove piqued some of his interest.

Davis wanted to see what kind of things the strong in the abyss would treat as treasures.

The thoughts of those Abyss Overlords he had encountered in the past were too chaotic.

There is no idea of creating a treasure house at all, and he can only harvest some godheads every time, which has to be embarrassing.

However, Davis's observation found that it was simply amazing.

In this huge treasure house with a length and width of more than 10,000 meters, there are not only mountains of Abyss Magic Stones, as well as a large number of precious demigod and god-level magic items, but also a lot of precious refining materials.

If it was just an ordinary refining material, Davis certainly wouldn't care.

However, among these materials, there are many suitable Immortal Dao refining tools.

This really made him overjoyed.

Over the years, Davis has continued to travel to all planes of the abyss.

Everywhere they went, they would also use formation flags to protect the gates of time and space in those planes.

In the beginning, his formation flag was quite sufficient.

However, as he went to more and more planes of the abyss, he was eventually consumed by him.

Later, Davis could only use some very pure magic stones to simply arrange a concealed and psychedelic formation.

And now, these refining materials in front of him were able to allow him to refine multiple array flags.

At the same time, the materials in the treasure house can not only be used to refine some spirit weapons.

A considerable part of them can already be used to refine immortal weapons.

A very small number of materials, even if they are used to create the Houtian Lingbao, are completely feasible.

After all, this 1,412-layer plane was much larger than the original Cangyue Continent.

In addition, there are many different abyssal planes connected.

A large number of other Abyssal Plane Demons will come here to trade with the treasures in their own planes.

After hundreds of millions of years of accumulation, it is understandable that there are such huge amounts and a wide variety of treasures.

With a wave of his hand, Davis directly moved everything in the treasure house into the cave world in his eyebrows.

Even the shelves in the treasure house were not spared.

After looking around and seeing that there was nothing missing, his figure flashed and returned to the palace where Grant Demon God cultivated again.

This palace is large, luxurious, very artistic, and full of energy, which is also extremely rich, which is an excellent place for cultivation.

Immediately made Davis a little interested, making him want to meditate and cultivate here for a while.

Of course, before cultivating, he had to refine some good quality formation flags first.

Then use the array flag to arrange a spirit gathering array in this luxurious palace.

Sharpen knives and do not chop wood by mistake.

With the assistance of the formation, his cultivation efficiency will be even more powerful.

If you want to do it, Davis immediately took out some of the refining materials that had just been collected not long ago from the Eyebrow Cave Heaven World, intending to refine them directly in this palace.

Of course, in addition to taking out the refining materials from the Dongtian World, there is also a refining furnace.

This refining furnace was originally refined by Davis when he was in the Cangyue Continent, and it belongs to the ranks of the ultimate spirit weapons.

Many spirit weapon array flags used to come from this refining furnace.

And today, it will come in handy again.

However, Davis did not immediately use it to refine the formation flag, but planned to use it to try to refine a higher-grade refining furnace.

Anyway, there are enough materials obtained from the Grant Demon God Treasury this time, even if it is bad, it doesn't matter.

And once he refines a higher-level refining furnace, then it will be easier to refine the formation flag in the future.

Davis puts the ingredients one by one into the furnace, and after they are melted into the essence, they are taken out for later use.

When all the materials for building the refining furnace have been refined, the real refining begins.

With thousands of years, Davis's strength has been greatly improved.

The last time he used to refine the weapon, he was still in the "fan" stage, and now, he has become an "immortal", and he has also mastered many "immortal" refining techniques.

This time, even if there was no real refining for many years, the first time he refined, he refined the ultimate spirit weapon level refining furnace.

This new refining furnace was even better quality than the refining furnace he had just used.

He put away the old refining furnace and continued refining with the new refining furnace.

For the first time he failed to refine a higher-grade refining furnace, his heart had already expected it, so he could not talk about disappointment.

The refining materials prepared just now were not just one, but as many as fifty.

Without stopping, Davis continued to start refining a new refining furnace.

As a result, the second copy was also at the level of the Ultimate Spirit Weapon, while the third copy was still the same.

......

Until the materials were consumed to the forty-sixth part, a huge amount of smoke rose from the refining furnace.

Davis finally refined a low-grade immortal-level refining furnace.

Even if it is only the lowest grade immortal weapon, it is far from being comparable to the ultimate spirit weapon.

In the process of refining, it can provide better refining assistance and improve the success rate and grade of refining.

At the same time, it can also be a certain degree of size satisfactory.

As small as a foot in circumference and as large as ten meters in diameter.

With its help, it will be much more convenient for Davis to think about refining in the future.

"Well, good."

He took out the shrunken Immortal Refining Furnace, put it in his hand and played with it, revealing a satisfied smile.

Then he took back the refining furnace just now and began to use this immortal weapon to officially refine the formation flag.

One by one, the materials were thrown into the refining furnace by Davis, and not long after, a array of flags flew out.
