Chapter 553 Thorium Crystal ignored Arthur, and a golden light flashed in Raine's eyes. More than a dozen vines grew from the ground and bound the dozen or so dwarves who were lying unconscious on the ground.

Raine waved to the elven guards on the tree branch.

The elf squad immediately jumped down from the tree branch and came to Renn. The elf captain bowed and said...

"Lord Renn."

Raine pointed to the dozen or so dwarves lying on the ground and said, "They're yours to take back to Ophelia."

“Let Ophelia interrogate them carefully. These are all elite dwarves. I suspect they came to the elven forest for more than just to steal minerals.”

The elf squad leader nodded: "Yes, I will relay this to Her Highness the Princess."

After doing all this, Renn disappeared from the spot and flew off to other parts of the Elf Forest.

After dealing with the other two dwarf squads in the northern part of the Elf Forest, Renn could no longer sense the presence of dwarves within the range of his mental energy.

He then flew toward the hidden magic circle in the northern part of the elven forest. On the way, Renn took out a spatial magic device that he had just obtained from the dwarves.

He asked himself, "Isa, see what's different about this magical artifact."

“Gregory must have other motives for sending the elite dwarves to steal ore.”

Isa, the spirit of the Book of Natural History, nodded slightly and then began to examine the items in the magic ring.

Not long after, Isa spoke:

“Master, besides some dwarven daily necessities and some potions, there are many ores in this magic ring, but most of them are quite common and have no special use.”

"Only one type of ore called Thorium Crystal seems a bit off to me. Judging from its appearance, the Thorium Crystal in the magical artifact is newly mined."

"This ore, called Thorium Crystal, is a ore between the fourth and fifth tiers. Although it is not a treasure that warriors or mages can absorb, nor is it a material for crafting equipment, it is an extremely energy-rich ore."

"Through some special methods, the energy produced by a single cerium crystal is comparable to that of hundreds of tons of coal."

Rein narrowed his eyes, and a pale blue ore immediately flew out of the magic ring in his hand.

“Energy ore… What is Gregory planning?” Renn muttered to himself.

Speaking of energy, Renn thought of a powerful weapon used by the dwarves.

Titans.

A man-made Tier 6 combatant crafted using dwarven techniques.

To activate such a powerful weapon, an extremely terrifying amount of energy is required, and this ore called Thorium Crystal can just make up for the lack of energy.

While pondering, Renn flew back to the location of the hidden magic circle. Looking at the nascent magic base in front of him, Renn stopped thinking about anything else and focused all his attention on the construction of the magic base.

Beside Renn stood several old elven magic scholars, their eyes fixed on Renn as he constructed the magic base.

After learning that Estella had obtained the long-distance magical teleportation base from Rein, they submitted a request to Estella to review it overnight.

These scholars, who were a generation older than Estella, certainly made significant contributions to the Elf Forest, enough to warrant an examination of the second-tier license.

So the next day they came to Renn’s side to observe the process of Renn building the magic base.

Having lived for so long, they naturally know that the process of constructing the magic pedestal in Renn is extremely meticulous.

Therefore, they stood silently in place, communicating only through telepathy, for fear of disturbing Renn.

After a morning's work, Ryan finished his day's work.

The next moment, the old elf who had been standing by all morning came to Renn's side and asked him about the question that had been on his mind regarding the construction of the magic base.

The group of elderly elves were generally at the fifth rank, with two of them even at the sixth rank.

Although these old scholars were embarrassed to ask questions of a junior like Renn, their thirst for knowledge compelled them to ask anyway.
