The people around were surprised to hear their Elders were giving their utmost respect to the disciples. They were unaware that Caelum was not a student , rather a guest to their Academy.
Han Yue who was more informed than the rest knew from the recent news about a rising individual only known as Tian Zun who had been changing the ways of alchemy.
She came from a family where they are well versed in alchemy and anything related. The pills that were able to get a hold by her family had allowed her sister to grow to the same level as her or even higher.
"No need to bow unless you're my enemy. I am only here out of boredom and curiosity."
This causes their elder to twitch on how he is taking the sealing of the essence flames that are capable of making them a dou zong/ancestor to do their best to seal it.
Essence flames over time depending on the scenario and environment would gradually form a definite shape such as Geocentric lotus essence flames that were in the shape of a lotus. Furthermore, they would gain their own consciousness though this is rare.
The first Dou Di was a sentient Essence flame that continuously devoured other flames and let him rise higher until reaching the Dou god state.
Caelum's own Primeval Dao flame was sentient and had it's own life yet still hadn't gained any form.
"Then follow us, we'll discuss more privately."
He only nodded before taking quick glances to Han Yue then winking at her who remained indifferent yet was drawn to his mysterious presence.
Without wasting time flew into the sky leaving the student dumbstruck that Caelum was able to fly without a Dou Wings. Along the way, the elders explained the situations about the essence flames expecting him to be wary yet his face was indifferent.
They wondered what made him to be this confident in facing an essence flames capable of giving them a run for their money.
Moments later, they arrived at the tower where the essence flames were currently residing and instantly felt the violent reaction of the entity. The student fellow noticed their arrival and gave their greetings receiving a nod then shouted.
"Today the tower is closed and everyone inside shall leave for the time being."
The elder announced causing the students to be disappointed as they had been anticipating to cultivate inside the tower. However, it was for their safety knowing the possibility for the Essence flames to escape.
Caelum tried to tell them it was not needed yet did not listen and let them be. He knew they didn't have any Ill intention and only concern for their disciples.
After a while, the students were brought out and directed Caelum inside where within a spatial lock was an enormous snake that was burning in flame.
"Feisty one are you?"
"You can see it?"
"Of course, I'm able to see anything and everything. Don't worry I don't need to do anything besides this."
Caelum decided to do some gift taking out a wisp of his Primeval Dao Flame that was more better and stable than the essence flame. The elder witness a small ember of flames came forth from his fingers ties and was confused.
Before they could do anything the small flames fell into the spatial locked essence flames passing through the barrier then in an instant the moment the Essence Flames came into contact with his flame was burned into a blaze.
Their tower instantly paves way for more stable nourishment that causes the other elder to break through their cultivation, shocking them. Everything was too fast for them to even comprehend everything.
"I plan for compensation."
Caelum took them out of their daze then stared at him in a new light. They were both terrified and amazed that someone this powerful exists.
"Thank you, Master Tian Zun for this gift if wish for anything then out Jia-"
"Wait, sorry to cut you but I only want to know if there's a student named Zi yan that is able to bypass the barrier?"
The elders staring among themselves before nodding as Zi yan was well known throughout the academy and enigma due to her unknown origin.
After the tower, Caelum was left to wait in one of the rooms as he began to cultivate his Sacred Scripture to further his path in true power. He had reached another bottleneck in the Sacred Scripture as he had not yet experienced a battle that boils his blood.
He decided to put it aside and took out his Immortal physique to begin in gaining them. Caelum decided to choose the [Indestructible Diamond] immortal physique that gives him instant regeneration that is nearly impossible to know how fast it is.
Caelum would be unkillable if he combined this with [Void Imperfection]. He began to cultivate the physique into his body instantly and felt his skin and flesh was able to repair it quicker than before.
Unlike the other first two physiques, Caelum took longer to reach the minor completion yet this time the tribulation had not formed. He only guessed it was due to recently breaking through the Empyrean God.
He took deep breaths, seeing the constant and instant repair of his body. This made him wonder if his body that had already no limits continuously tempered and refined.
Caelum decided to rest it by doing a simple exercise that brings out the most of his muscles. The tearing and shredding muscle fiber was excruciating yet was immediately healed.
He stopped his exercise then placed his hand into his chest instantly causing his whole body to vanish leaving parts of his legs and arms along with his head hovering for less than a nanosecond before it healed instantly.
'Damn that hurts! Even using the destruction energy had little effect to slow it down. This is only the Minor huh….I really have the protagonist luck.'
Caelum chuckled, seeing his body heals even included clothes without any imperfections. He did not know how long his regeneration and what limit it could take before slowing down.
Even immortals need precise concentration to regenerate and taking too much would result in their regeneration to get slower. Though, this doesn't apply to other entities that have true immortality.
He tested the limits of his regeneration and found that depending on the energy use would have different results where his body slowest to regenerate was Primordial Chaos Qi and few weapons in his Gate of Babylon as well as Blade realm. The slowest was nine second to fully regenerate.
Of course, Caelum had not even included time manipulation to speed up their generation even further. He went outside as the elder came inside to call for him.
He was led to the room where Zi Yan appeared to little girls with long pinkish hair dressed in violet-ish outfits. Caelum saw her shudder seeing him appear already to feel the connection.
She was a member of Ancient Void Dragon and daughter of the leader. Caelum, the bloodline of the Ancestral Void Dragon God, could consider him as the progenitor.
The reason why bloodlines had will in the past was due to the progenitor rejecting him but once he absorbed them into his body had turned him into a sort of successor to them. Caelum lack one thing which was why he wanted to meet Zi Yan.
"W-Who are you, why am I…"
The elder noticed her quivering body and tried to calm her down only to find she was not there but was in front of Caelum who kneeled down patting her head.
"Zi Yan, my name is Tian Zun and I know where you came from."
"You do!? Tell me tell me! I want to know what I am!?"
"Hehehe calm down. You came from the Ancient Void Dragon clan and I also know where your father is."
While he was speaking and explaining everything to her had extracted a blood from her containing the essence needed to advance his bloodline.
He absorbed the blood instantly causing the bloodline statue to shake and change form where his eastern Dragon who similar to Aurelion Sol grew a pair of wings that had a gold stem akin to his head and the wings was a sheet of flowing galaxy.
The sound echoed through his Sea of Conscious before calming down and felt his Body to improve not in strength but felt like gaining a missing piece.
"Let's meet up with your father."
