The first one who gave the endurance test was Nagisa. She went onto the platform sat cross-legged with her eyes closed. The device created a barrier around it and started the test as programmed. First, it was the test of physical endurance. As configured the gravity on her increase by 0.5 with each passing minute. 

0.5, 1.0, 1.5, 2.0, 2.5, 3.0!!!

That's where she gave up. So her physical endurance was noted as 2.5 of normal gravitational force. Now it was the time for mental endurance and the test that Ryan had been waiting for. The gravity on her came back to normal and gave her some time to catch up with her breath.

Just when she was getting ready for the second test the device caught her off guard and emitted the specially designed rays on her. 

Thud!!

She became unconscious inside the device. Ryan got worried and was about to ask something when Mr. Robert intervened and said, "She is alright. She is just facing an internal demon now."

"Okay..... But," Ryan was about to argue something when a sound came for the device. He turned around and found Nagisa was already out of the device.

"Ehhh…..?!! How is this possible? You defeated your internal demon that quick? Even then it was an artificial one, it should take some hour at the least to defeat it."

"Hmm… Friend Ryan do you know who is the ancestor of the Hiragi Family?"

"No….. Who is it?"

"One of the Seven Sages who was an exorcist was the ancestor of our family."

"Oh…..!!" exclaimed Ryan. But deep inside he got a heart attack. Finally, he got a hint about one of the Seven Sages. Now all he had to do was, to enter the Hiragi household and read the old records. But while he was rejoicing over it he membered something that was discussed in the class.

"Nagisa chan, if I remember correctly the Hiragi's have a martial arts background, right?!! Then how come you are saying, that they are from an onmyoji (exorcists) background now?"

Before Nagisa replies to his question Mr. Robert intervened and explained, that the ancestor of the Hiragi family was an onmyoji from the very beginning. But as the spell incarnation and chanting of onmyoji were quite long, he devised different ways of martial arts to weaken ghosts, demons and their kind. Later the second generation family head of the Hiragi family modified them and made them suitable to use on humans.

"Oho," exclaimed Ryan and asked the question that was bugging him for a while. "Then Nagisa chan, how did you subdue your internal demon?" asked Ryan with curiosity. Because in ancient times no spell, magic, or trick existed using which someone can subdue their internal demon. 

All they could do was to fight with the internal demons with a strong will. And if they waver or hesitated for a second their mind, body and soul will be taken over by the internal demon.

"Mantra incantation," replied Nagisa.

"Mantra incantation?!! Your family secret ones?"

"Yes, only those of the Hiragi family bloodline can use it. Not even Mr. Robert can use it."

"Oh…. I see,"

"There is a prophecy in our family, passing down from the ancient times" added Nagisa. "That a day will come when an outsider will be able to use the same mantra incantation that is exclusive to the Hiragi Bloodline only and that person will be.."

"Ahem, young miss, I don't think we should discuss such things here," commented Mr. Robert. Nagisa came to her senses and stooped talking about the Hiragi family secrets. Just a few minutes ago, when she came out of the endurance measuring device instead of going near the medical team for a health checkup she went in the direction where Ryan was standing with Mr. Robert.

It was like she was getting attracted towards Ryan by an unknown force. And this unknown force was one of Ryan's cultivation star that was creating a resonance between the star and Nagisa.

After Nagisa's turn, it was the turn of other students of the class. Many of them tried but none of them could beat the 2.5x gravity record of Nagisa. Only Rajesh was the only one who scored 2.4x gravity record, somewhat nearer to Nagisa's record. 

And for the second test very few of them passed the internal demon test. The one who failed screeched in the end to show that the internal demon has taken over their body. The most interesting thing in this event was none of the kids afraid of giving the second test. Cause every one of them knew that the internal demon was artificial, and even if they failed the test, it won't take over their soul, body ad mind.

Ryan was the last one in line, all this time he had been chatting about various things with Nagisa and Mr. Robert, the medical team called out Mr. Robert informing the completion of the test for the entire class excluding that boy standing near him. Mr. Robert asked Ryan to go and give the last as the last remaining student.

As instructed by Mr. Robert, Ryan went to the platform and sat cross-legged and eyes closed. The first test was the gravity test as usual. Ryan started from 0.5 and stopped at a number that seemed like a lie even to Mr. Robert.

0.5, 10.0, 19.5, 29.0, 30.5, 39.0, 50.0!!

That's when Ryan faced some problems and asked them to stop the device. Except Mr. Robert, everybody had a shocked expression on their faces. A seven-year-old kid who can withstand 50x gravity!!

Was not a small feat, not at all. Even the most talented youngest prodigy of the Hiragi family, Nagisa could endure up to 2.5x.. But the boy before them was something out of the planet, showing them miracles upon miracles that they have never imagined of, not even in their wildest dreams and fantasies.
