There are many reasons for a powerful sect as the Sect Origin Avenue to settle in a floating island in the sky, as you can believe it's unsafe to do it.
In first place the island has a very abundant Origin Qi, and it guarantees that is inaccessible the access for any mortal or cultivator that cannot fly or doesn't have the sect's permission. An obvious reason is to show status and strength.
In the Myriad Immortal World where people can cultivates to high and powerful levels of strength, to a organization to show part of their strength in such things is important to warn people to not mess with them.
And is not as dangerous as it seems, the island is not going to fall even if you absorb a monstrous amount of Qi from it because it is in a intersection section of spiritual veins that connects directly with the world, so it's not going to fall no matter what.
And any person who haves the strength to make it fall by force logically have the strength to do the same to a mountain or valley from any other sect and that's the reason why sects have powerful formations for protection.
And the sect is not small, it is so big that the island have their own mountains in here. All the island is at least as big as whole country And the area of the headquarters of the sect is like a City for the disciples, teachers and servants of the sect.
People More important like the Elders and Great Elders and their families have their own residences on their own Mountain peaks, near to the Sects Master's Palace where Hou Zhi leaves.
The Other Areas outside the 'Main sect' are destined to other facilities and purposes. And this is just their Headquarters not to talk about the giant region where they rule that is bigger than the earth itself. Where live the mortals and cultivators that are not part of the sect.
This World is so big that all the Main forces have control of their own region of it that is bigger than a lot of worlds. Even smaller forces can allow their selfs to rule smaller areas.
Hou Zhi was very surprised when he discovered this world is approximately as big as the Sun, but the most surprising is that the gravity is not as strength as he would imagine, because logically in a world as big as the sun according to science the gravity will be that strong that you will be no more than a stain on the floor.
Then Hou Zhi finally arrived to his destination, the Sect Master's Palace, that is actually his house.
When he entered he was received by his mom.
"Hou Zhi, where were you? Your father has been waiting for you in his room for a while"
"Sorry Mother, I was nervous about today"
Yes, today is a special day, today Hou Zhi will finally his own cultivation trip. After waiting 10 years Hou Zhi finally can begin his cultivation trip, he will receive their parents approval and begin to cultivate.
"It's okay, I was nervous the day I finally begin my cultivator trip".
They walked together until they entered on a room.
"Hou Zhi, good morning so what's the excuse of today?" His father said
"Good morning, father" Hou Zhi said. "There's no excuse I was nervous so I go outside to watch the clouds"
"sigh, Okay, you know what day is today, no?"
"Yes! Today I'm gonna finally receive a cultivation technique and begin to prepare to breakthrough to the Body Refining stage"
His father nodded with the head. His mother that at some point moved next to his father was nodding to.
"So, are you ready?"
"Yes"
Inmediatly after giving approval, an incredible pressure came out from his parents. From his father an incredible Sword Intention has been released. From his mother, a Fire Will that burns it everything. Each one of them maid difficult to him to breathe and make him feel like it has a mountain in the back.
Then, with their voices intertwined both said"
"Are you sure you want to walk through the cultivation path? It's not going to be easy, and you sure are gonna fall many times at the way but when you put a step in into it, then is better for you to be decided to walk it to the end"
With his will reaffirmed Hou Zhi answered"
"Yes, I'm sure"
Then the pressure faded into nothing.
This time Hou Zhi finally remembered that his parents are powerful cultivators in the Sovereign Realm and not just a the face he see of them. They probably even killed a lot of people to reach the point where they are and he probably will do the same, but that's not enough for make him refuse to be a cultivator.
Even in his past life he know a lot of people died in his failure experiments that make him the miracle medic he was. Even if it would be different, he's not going to hesitate here.
"Congratulations Zhi'er you finally are gonna be a cultivator! " His mother came to him and hugged him hard.
"Your mother is right, if you would doubted earlier we never would give you a cultivation technique until we believe you were ready". His father said
"But, until you have passed that little test…" His Mother said, then he looked at his father face like waiting something.
When his father noticed that he immediately snapped his fingers and something appeared into his hands. It were a bamboo slip and a black ring.
"In the bamboo slip is the first volume of the "Origin path" is the highest level guide that explains all about the cultivation that a cultivator needs and the black ring is a storage rings, it's pretty small but it doesn't needs Qi to work, you just need to think what about you want to keep in and the ring will do the rest. His father said.
"Thanks father" Hou Zhi said and he immediately take bamboo and the ring from his father, and put the ring in his finger, then with his will he put in it the ring.
"So~ now that that ends let's party that our Zhi'er is going to begin his journey as a cultivator!" His mother said.
"That's a great idea! Let's go dinner, I will order to the servants to prepare a feast to celebrate!"
"Okay, let's go" Hou Zhi was used to the spontaneous of his mother, but he decided to have fun because there will not be so many opportunities to it in the future.
He suddenly feel a chill and a gleam flashed in her eyes. He turned to see the sky and too see a shooting star. "I hope it's not a bad omen" he thought.
And then the party begins.
