"We broke the seal with the Dragonslayer Staff, and it looks like it was a seal set by the Dragonslayer Mage Rune himself. One of the surviving snow elves told Lange and Deco.

"And then, what's down there?" Decoin gave him a sip of water, and just three days ago it was still a paradise for snow elves. Now there are only two clansmen left.

The Snow Elf's eyes were filled with fear all of a sudden: "One, an ever-changing ball of light. ”

Ball of light?Lange muttered to himself, and he looked into the abyss in the distance, where there was not a glimmer of light.

A ball of light engulfed it all?

"High Priest······ The High Priest said that it was the source of magic, from which almost infinite energy gushed out. The Snow Elf said.

This is it, all the secrets of the Blue Sacred Tree, everything in the magical world, the source of magic.

Decoin didn't know what to say: "So what······ Will it turn out like this?"

"It seems to like the Dragon Slayer Staff, we didn't know it at first, and I didn't realize it until it was too late after it devoured the Dragon Slayer Staff. The snow elf recalled the terrifying sight of that day, and the orb of light that devoured the staff erupted with terrifying energy, turning the place into an abyss.

The Snow Elves are reluctant to leave the Blue Tree, and Lange and Dewen say goodbye to him and continue on their way. They went to the Hermitage of the Duchy of Falls, where the oldest sources were found.

Lange meets Suman at the Winter Palace, who gets special permission for the two of them, and the three of them enter the lowest room to search for information about the dragon slayer mage Rune.

"What is this?" Lange, who was already able to read, found a drawing, a Horcrux designed by Rune. It's like a mechanical umbrella.

"Rainbow?" Su Man read, this is a special weapon, as long as there is enough energy to support it, it can penetrate all objects, and judging by its shape, it can also fly upwards.

"Why did Rune design such a thing?" all three were puzzled. Two nights later, Decoin found a description of the Blue Tree in another draft, and although Luan did not mention the name, Decoin knew from a few descriptions that it was the home of the Snow Elves.

"It craves dragon's blood. Decoin suddenly understood, "The dragon slaying staff must have dragon blood, and dragon blood is used as bait to lead that light all the way up to ······ Another world!"

"Wait. Lange didn't quite understand, "Why are we directing that light to another world, isn't that the source of magic?"

Dewen and Suman fell into deep thought at the same time.

"What would happen to the dragon without magic?" asked Suman Murmur.

"Then they're a bunch of big beasts. Decoin came to her senses. Together, the three convince Grand Duke Ned, who decides to do everything in his power to create a rainbow. The best alchemists gather in the Winter Palace, and the psychic Si Yi takes the griffin to bring the dragon's blood that Vayne has traded for his life. The army of the orcs marched towards the Duchy of Lox, and it was overwhelming all the way. Lange and Decoin take the rainbow they have built and head to the Blue Tree.

"Will this thing be useful?" Lange felt that so many people's lives were exchanged for an unknown answer, what if Rune was wrong?

"There is no way to go. Suman sent Lange and the others away, and stood in the Winter Palace with the last of the resistance, attracting the attention of the dragons.
