Evan had already guessed the true origin of ancient voice. His guess was that the ancient voice was a powerful artifact spirit from ancient times. But he had yet to confirm his assumption.
Evan had already expressed his desire to enter the world inside the door. After some time he listened the strange ancient voice again,
"As the ninth approved devil of Hendrickson family, you can venture into the world of Devil Codex freely. But you can only enter it with your physical body. Moreover, you must not reveal what you see here to anyone."
Evan felt astonishment after listening the ancient voice as he wondered where would his physical body go. Everything related to Devil codex was very mysterious to him. He felt that his family heirloom hiding a great secret.
He thought to himself, 'I have almost seven hours remaining. It will be morning after that. I will return within this seven hour period. Even if someone finds me missing, I will handle the situation after I return."
Then he spoke, "I want to enter inside the door."
He didn't get a reply immediately but what happened after sometime give him a huge shock. His jaw dropped as he saw the huge door turned into a huge teleportation portal. He never saw such complex and magical portal in his entire life."
Within few second the teleportation portal fully activated and his body was sucked into devil codex. He disappeared and the rectangular jade also disappeared into thin air.
Evan could tell that he was crossing huge distance in an astonishing speed. After some time, teleportation stopped and Evan walked out of a similar looking portal.
It was an ancient looking grey world. Surrounding was covered with swirling airstreams of darkness. Evan murmured, "Surprisingly this devil codex holds a teleportation portal to an ancient world. I bet, even grandfather did not know about it and this place is a suitable place for the cultivation of darkness element".
Evan decided to first explore the world. He looked infront of him and saw three huge stone slabs erected in a distance. He walked toward it and saw a huge list of names written on it but when he looked towards the names, he found the names on top were blurred.
Currently his name was glowing in a bright manner at the bottom line of slabs. On first slab, 'Royal' word was written. Moreover it was written in ancient language of devils. Similarly the word 'Contribution' and 'cultivation' written on other two slabs respectively.
Evan was again surprised. He felt his soul aura inside his written name. He deduced this was a way to store informations about powerful Hendrickson clan members. He then crossed the stone slab and proceeded toward other parts of island. After walking for sometime, he reached a land which was full of fire. Extreme heat was being emitted from it. Drops of sweats fell down from face of Evan. He still proceeded forward. He knew he had to get stronger to go further in this world.
'It must be an arrangement to train powerful members of our family', he thought to himself. Evan came back to the starting area and seat crosslegged. He started to breath in a strange pattern. This was a cultivation technique to control elements and it was taught to him by his grandfather. It was an unique technique only passed to his Hendrickson family. The name of this technique was 'ancient element devouring technique'.
After some time strands of darkness could be seen floating towards him. Evan continued his cultivation and four hours passed like this.
strands of darkness were swirling around him. Evan grinned slightly and murmured, "middle stage of element sensing realm".
Others may go crazy if they have such cultivation speed, but Evan did not felt anything.
Afterall,a royal devil soul was already in a higher cultivation base from the beginning.
They only had to tune their body cultivation base to match their soul.
There were various realms in the cultivation path. Each realm was much harder to cultivate than its previous realm .
First stage of cultivation was 'Element sensing realm.
It was followed by Meridian opening realm and Profound transformation realm. These three were called as the foundation realms.
After it, there was Core condensation realm which was now out of reach for Evan. He decided to start his cultivation because there was a single cultivation system for every entities who resided inside the universe.
Although cultivation pattern vary somehow in different types of racess but ultimately all cultivation pattern lead toward same power level in Universe.
From their birth, gods had elemental core inside their body and devils had devil soul.
Humans didn't have any such cultivation advantages as elemental core or devil soul. They had to practice hard cultivation to establish core or turn their soul into devil soul.
That's why humans revered gods and fear devils. Anyone would fear such natural freaks like gods or devils who had such cultivation advantages from their birth.
But gods and devils have lower reproduction rate and gods who had royal blood or devils who had Royal soul were as rare as a phoenix feather or qilin horn.
Evan stood up and walked towards the teleportation portal. Before he could leave, he heard a strange voice that sounded ancient yet different from the previous voice.
"Are you sure, you want to go outside. Once you go, you have to wait for another month to come again."
Evan nodded and said, "No problem, I will come back after one month."
Evan walked toward teleportation poertal and disappeared within. He had already figured out the identity of new voice inside his mind, "It must be another artifact spirit who reside inside this ancient world. Our ancestors were surely mighty and extremely knowledgeable in crafting artifacts and building portals."
Evan walked towards teleportation portal and appeared inside his room. After cultivating for several hours, he felt tired in his mind.
Evan knew what was best method to releive the tiredness. So, he closed his eyes and went for a sleep.
