Mana crystals possess huge amounts of pure mana. It existed as one of the best mana sources, and one of the easiest to use. It could be used for direct absorption during meditation to boost the effects of meditation. Although mana crystals don't increase the size of the mana pool, they have the ability to both strengthen the suction force of the "Mana Seed" and increase the total amount of mana units in the mana pool. Moreover, because the mana present in the mana crystals are the purest, there is simply no need to worry about impurities. Thus, the importance of Mana crystals could be seen from just this fact, it was without impurities and easily absorbable.

The mana crystal can be used as a catalyst to strengthen the suction force of the mana seed. By just this effect, the mana crystal is extremely high priced in the market. The price of mana crystals is determined by their size. A low-rank mana crystal will sell for enough that one would be able to enjoy his life for a year.

Normally, mana sources have many impurities. The mages wouldn't dare to absorb impure mana. As the number of impurities entering the mana pool would cause serious trouble for any mage. That's why magical beast cores undergo a purification process before a mage can absorb it; However, Whittaker could absorb mana sources with impurities without any problems as he was a "Devansha".

According to Nina's information, the Devansha are actively hunted down for their blood by mysterious groups because of the mysterious powers the blue blood gives. Thus, Whittaker had been hiding the fact that he is a descendant of the Devansha both in real life and the Monster Tower Dungeon. Being hunted down is also the reason for Grey worries mentioned in the book of gossips.

Furthermore, the mana crystals could be used for operating a formation, they can fulfill the mana requirements of the formation items, which in turn, leads to the erection of the formation. Thus, the user of the formation is not burdened by the tremendous amount of mana required by the formation items to erect a formation.

"Hmm, it's gonna take some time to open the door to the inner treasury. The treasury has not been used for years and the doors have become rusty with time. It has to be opened manually," Nina said before manually opening the locks of the Golden Door Formation by using the key of the treasury.

There were more than a hundred locks and it will take a lot of time for her to open the Golden Door Formation. Whittaker and Zachary couldn't help as there was only one key.

The treasury was divided into the inner treasury and outer treasury. The outer treasury only had mana crystals and the inner treasury contained the true treasures.

"Elder, it's gonna take some time before the Golden door is opened, can I play with the treasures here?" Whittaker asked for permission.

"Sure, go ahead and do whatever you want to do." Elder Zachary gave him permission and Whittaker walked up to the mountains of mana crystals.

While activating his mana meditation technique, Whittaker picked up a "small" mana crystal and quickly drew the mana from within. The pure mana of the small mana crystal instantly blended into Whittaker's mana pool. At the same time, the mana seed suction force increased by a barely noticeable percentage.

"Hahaha, don't be in such a hurry. The treasures here are all yours to enjoy. You can store them in your spatial ring and absorb them in peace after we return to the palace."

Seeing his actions, Zachary laughed and instructed him to store these mana crystals for future use.

"Sure," Whittaker began to store several thousands of them in his rankless ring of genesis. Whereas Nina focused on opening the golden door formation that is securing the inner layer of the treasury from invaders.

"It must have taken Elder a lot of time to collect so many mana crystals. How many natural dungeons did you complete?" Whittaker asked with a look of wonderment while collecting more mana crystals.

According to the books, natural dungeons are created in places that have accumulated a lot of mana. The accumulation of mana warps a simple place such as a normal mountain, cave, and similar places into a deadly dungeon.

At the deepest part of the natural dungeon, there is a giant mana crystal, and there is a guardian that protects it. The giant mana crystals can be broken down into dozens, hundreds, or thousands of pieces depending on the rank of the natural dungeons, while the guardian of a natural dungeon is twofold or more powerful than the boss of the natural dungeon. The natural dungeon won't vanish unless the mana crystal is destroyed or collected. Thus, the dungeon creates the strongest monster it can to protect the core of the dungeon. The core of the natural dungeon is its mana source. And it is also the giant mana crystal.

"Indeed, it did. In my youth, I was a lot active when compared to now. I had a lot of friends and challenging natural dungeons with a high chance of death was very common for our group. As you may know already, the Mana Crystal and the Guardian Item is a strong bait. It has a strong temptation to every adventure and we were no less tempted by it than the average joe. Confronting the dangers of the natural dungeons, we completed a lot of them numbering in hundreds of low-rank ones and dozens of high-rank ones, and shared the giant mana crystal according to the contribution of the party's members."

There was a high chance of death in a natural dungeon. It takes a lot of bravery to venture into a natural dungeon while knowing the risk of death

"This is pretty much the entire amount of mana crystal left from what I have accumulated over the years by completing the natural dungeon of various ranks," Zachary had used a lot of them to create Zachary's Palace and then a lot were also used over the years, and he was left with just this much.

"I am guessing that there are more small mana crystals here than the treasury of the big cities or even the imperial cities." Even this much was more than what Whittaker could ask for.
