Dyon slightly trembled as he clutched the red-gold medallion. He knew nothing within Orcus' core legacy could be common, but when he first saw this medallion, he was skeptical. He couldn't see anything special about it. But, when he sent his senses inside, he immediately understood what it was. This medallion was a Mending Core.

Mending Cores had long since gone extinct. This wasn't because they were a lifeform of some sort, but rather because humans with the skill necessary to form them stopped appearing. Of the four Eras, the Modern Era was most definitely the weakest and least informed. As the Chaos ratio increased, the dregs of history and past accomplishments were wiped away. Maybe the only true remnants that remained of the past ages were on the Ancient Battlefield.

The secrets of Mending Cores were labored over to great depths within the [Dao of Array Alchemy]. Unfortunately, the minimum requirement needed to forge one was the Star Lord realm, something Dyon was very far away from as things stood now.

The purpose of Mending Cores is hidden within its name. They're created to reconstruct, fix, and build. However, the true magic of these devices was that they needed no further programming. No matter what the task was, a Mending Core would be able to immediately analyze the situation and after being provided with enough energy, could proceed to fix what was broken to its peak state.

Mending Cores weren't restricted either. In fact, they almost had no limitations at all since even the lowest was classified as a 7th tier supreme grade treasure.

Once a treasure enters the seventh tier, they are denoted as Star Treasure ranging from the first to the sixth level. Fourth, fifth and sixth tier star treasures are called pseudo treasures of the 33 heavens. While, obviously, true treasures of the 33 heavens are even above this ranking.

As one might expect, Mending Cores thus ranged from 1 Star Treasures to 6 Star Treasures. What separated these treasures' ranks would be both the difficulty of repair it could withstand and also the amount of energy needed for a given repair thus, efficiency. A 6 Star Mending Core would need far less energy to accomplish the same task as a 1 Star Mending Core.

The one currently in Dyon's hand was a mighty 4 Star Mending Core! Even at their peak such a Mending Core was incredibly rare. It was no wonder Orcus treasured it.

In theory, even if it was a damaged treasure of the 33 Heavens, a Mending Core had a chance to repair if one was willing to spend an ungodly amount of energy stones. However, this wasn't what Dyon wanted to use this amazing treasure for. He wanted to use this 4 Star Mending Core to rebuild the Celestial Deer Sect!

When Dyon first found the ruins of his sect and his master, he had relied on its training rooms to forcibly gain some comprehension of wills. However, he hadn't used them since then. It wasn't because he had forgotten about these rooms, but rather that they were too useless to him now.

How could a grand Sect like the Celestial Deer Sect, one that was even feared by the Clans of the outer quadrants, only have training rooms capable of helping comprehend wills alone?

At their peak, these celestial deer sect training rooms could accommodate even dao experts in their comprehension!

If Dyon allowed the Mending Core to repair the Celestial Deer Sect to its original stature, not only would he gain a second base of operations, but the formations that once protected and supported the sect would fall into his hands once more, formations Dyon had neither the skill or resources to create as of now.

This wasn't all Dyon wanted to repair either. Back when he first met Ri and entered the Elvin Tombs, he took the two Sentries for himself. It was in large part to these Sentries that Dyon was even alive today. One of them was responsible for Matriarch Niveus' death, while the other, although in complete ruin now, was responsible for helping him survive the combined assault of Loki and Elder Daiyu.

Dyon remembered that the first time he analyzed the puppets, he found that their energy absorption arrays were greatly damaged. Their dao absorption arrays were in tatters, while their celestial absorption arrays were only good enough to sustain the lower celestial realms.

Obviously, the strength of those puppets as things stood now was useless to Dyon. He could defeat a puppet with such strength with a single finger. However, Dyon also remembered that the peak strength of the Sentries was the Peak Dao Realm!

One might wonder why Dyon cared for this. After all, after Evangeline opened the second floor of the Demon Sage Tower, he had gained access to twenty dao puppets now. The answer was simple: cost!

The Demon Sage Tower fell from the immortal plane. The fact that the puppets within it could even be used with normal energy stones was a blessing in and of itself, but the cost was astronomical.

Remember, in order to power a single puppet for just 1 minute, it required 1000 energy stones of the corresponding ranking! To make matters worse, that was only if you wanted the lowest tier performance. Meaning, if you fed a saint puppet 1000 saint stones, you'd receive 1 minute of battle prowess at the 1st saint stage. If you wanted to push it to the 2nd saint stage you'd only have 6 seconds if it was the 3rd, you'd only have 0.6 seconds If you wanted the full minute, you would need to invest 10 000 saint stones for the 2nd stage and 100 000 for the 3rd!

For the dao realm, the cost was even more unsightly

In regards to the dao puppets, everyone knew that there were three tiers. Dao Stones, transcendent stones and enigmatic stones. Dao stones corresponded to the 1st to 4th dao stages, transcendent the 5th to 8th, and finally, enigmatic the 9th to 12th.

If Dyon wanted a Peak Dao puppet for 1 minute the 10th dao stage he would need 10 000 enigmatic stones. This meant 10 000 000 000 transcendent stones and 10 000 000 000 000 000 dao stones! For just a single minute!
