As Asher followed behind Aria and Rias, alongside Scarlet and Cecil, he got a message that made him frown and stop following, and he said, "Mom, we got a situation."
Aria stopped and turned to her son, "What is it?"
"Nadia is about to break through to the next realm of cultivation and requires a place to do so, since that place is not suitable for it." He stated.
Upon hearing this, Aria raised her eyebrows in surprise and smiled. "She finally reached that level, huh? I guess that's to be expected considering the fact that she's been practicing hard every day in that place."
"Do you know where we should go for her breakthrough?"
"Hmm..." Aria thought for a moment before answering, "There is indeed such a place within the sect where cultivators could go through their breakthroughs. However, it is reserved for the higher-ranking members of the sect, so outsiders aren't allowed to use it unless granted permission by one of the Core Elders, but since I am here, there shouldn't be a problem. Let's go."
Rias furrowed her brows upon hearing this, but she didn't say anything as this was indeed the case and she couldn't deny the truth in her words. Thus, she followed behind them with Scarlet and Cecil in tow.
The group of five headed toward a specific part of the sect. It was a remote area located near the mountains that surrounded the sect. There was nothing special about it except for the barren land that stretched across its surface, making it seem like an empty plain devoid of life.
However, this place possessed a mysterious energy that permeated everything within its boundaries, making anyone feel that they were being observed by something beyond their comprehension and senses.
Once they arrived there, Rias stopped moving forward and asked, "So, where is the person who is going to break through? How will they come here?"
When she reached a certain point, she stopped and sat down cross-legged on top of the ground, closing her eyes while taking deep breaths as if preparing herself for what was to come next.
"Mom, what do you think? Is there anything else I should know about this whole process?" Asher turned his head toward Aria.
She looked at him and explained, "Usually, when someone breaks through the next level of cultivation after having reached the peak of the Nascent Soul Realm, they would undergo a Heavenly Tribulation in order to prove themselves worthy of ascending higher in the cultivation world.
As cultivation is the journey to perfection, only those who are capable of withstanding the Heavenly Tribulation could continue further down their path."
"Since Nadia has already reached the peak of the Saint Realm, she now has to face the tribulation in order to ascend into the next level of power, which is the King Realm. She would have to endure a lightning tribulation where the heavens would strike at her with powerful bolts of lightning that contain tremendous energy.
If she fails to withstand it, then she will suffer heavy injuries or even die."
Aria paused for a second before continuing, "Of course, Nadia has been preparing herself for this occasion for a long time, so there is nothing to worry about."
Asher listened with rapt attention as he tried to understand the situation more, knowing that he may have to go through the same thing someday when he reaches that level of strength.
'But why did Nadia ask to come out for tribulation? Wouldn't it have been better if she faced her tribulation inside the Mystic Starry Realm?' He pondered and searched for that information in the Astral Nexus Core Orb and soon got an answer, 'Ahh, that explains things.'
In the Mystic Starry Realm, the spiritual energy density is rich, which will increase the speed and efficiency of cultivation. However, that place is now closed off and hidden from the reach of heaven, which makes it impossible for anyone to receive the Heavenly Tribulation there.
Only after the master of the Mystic Starry Realm breaks through to the Transcending Realm can that place once again allow cultivators to have Heavenly Tribulation.
