Since Kaier even mentioned Lord Esos, Dox had nothing more to say.
However, Kaier also understood that while his mentor advised him to follow Angel’s arrangements, it was meant for everything related to alchemy, not the door.
But Kaier didn’t mind; as a research enthusiast, he was quite interested in researching relics, and the door corresponding to the key had been a longstanding wish of his.
Besides, without Angel’s help, he definitely couldn’t find the path. So let Angel join; even if Angel gets the treasure first, Kaier believes that for the sake of Lord Esos, Angel wouldn’t let him leave empty-handed.
Even if there’s really nothing to gain, studying the relics would be a form of reward.
After getting a satisfactory response, Angel said, "I still have other matters in Barbarian Cave, and time is scarce, so I’ll begin decrypting the alchemy blueprints now."
After speaking, Angel glanced at Kaier and Dox, then looked at the distant passage of the Earth Cavern, the implication clear.
Kaier: "Then I’ll take my leave first. If you have any instructions, you can touch the nearby space nodes, and I’ll come at once."
The entire Earth Cavern had space nodes set up by Kaier, serving as a defense measure, but also acting like alarm bells. Once triggered, Kaier would immediately sense it.
Angel nodded and looked at Dox.
Dox gave Angel a deep look, said nothing more, and left with Kaier.
When only Angel remained in the Earth Cavern, he slowly sat down and reopened the stack of thick parchment.
As soon as the parchment was opened, Dangross on his shoulder began spinning dizzily.
"Why don’t you return to the bracelet for now?" Angel suggested.
Dangross shook his head quickly: "No, Heideland is mute. I don’t want to face it."
Angel: "..." You’re mistaken, Heideland isn’t mute, it’s just dumb—a trait inherent to the Void Traveler.
Dangross pointed to the quenched liquid in his hand: "I want to find a place to soak this."
Angel thought for a moment, took out the Geometric Lock, isolated the spiritual power assault of the parchment, and then laid out a concave fireproof stone ore inside the Geometric Lock, which served as a bath for Dangross by pouring the quenched liquid into it.
After solving Dangross’s problem, Angel sent Speedy to guard the door and refocused his attention on the parchment.
Angel could feel the spiritual power surge emanating from the parchment. However, since Angel had once endured the same nature but even more violent spiritual power surges, he had developed a certain immunity.
That is from the first time Angel entered the Nightmare Abyss City in the Nightmare Realm, where in the Underground Labyrinth, he encountered that mysterious wall and was forced to endure a spiritual power surge.
If it weren’t for the help from the Maneater Flower King, Angel might have died on the spot.
The spiritual power surge from this alchemy blueprint was almost identical to the surge he encountered from that wall in the Nightmare Realm.
Because of this, Angel inquired Kaier whether it came from The Garden Labyrinth.
There was no way Kaier could have gone to the Nightmare Realm, so having the same nature meant it could only be a counterpart from the real-world Garden Labyrinth.
Sure enough, that was the case.
Upon receiving this answer, Angel had a strong premonition that the short sword crafted from this alchemy blueprint was definitely related to the wall in Naraku City of the Nightmare Realm. It might even be capable of opening that wall.
However, the wall in the Nightmare Realm was extremely mysterious and terrifying. According to Sanders, he didn’t even have the privilege to approach and witness the wall. Angel was purely lucky and had a significant identity in the Nightmare Realm that allowed him to enter that corridor and see the wall.
Angel still dared not touch the wall in the Nightmare Realm, but if there was a similar wall in reality, he could investigate it first.
This is why he hinted that he could provide help in finding the door corresponding to the key.
Firstly, he himself wanted to explore it to prepare for that wall in the future Nightmare Abyss City. Secondly, even without his help, with the connection between the key and the door, they might find a Prophet Wizard to locate it.
Since a Prophet Wizard might find it, he simply mentioned it before they thought of this layer.
It turned out to be the right move.
Angel successfully joined the ’treasure hunt’ team.
It’s just uncertain if there truly exists such a wall in reality, like in Naraku City of the Nightmare Realm.
Angel shook his head, ceased pondering, and began to decrypt at his desk.
