Kai looked at the broken fragment of silver in Bob's hand and tilted his head sideways in confusion. What was this supposed to be? Garbage?
"Haha! Young Master Kai. If you look at it really closely, you will see countless incredibly small patterns on it! I don't know what it says, but I bought it for almost 10 copper from another merchant just to bring it to you!"
"Oh? Let me see it!" Kai said as he took the fragment of silver and turned it around a little to try and get the perfect angle in relation to the sun to get the clearest view of the stuff written on it.

'Huh?' Kai was thoroughly confused and did not react in time. Immediately, the fragment of silver with engravings on it fell from his hands as he too collapsed onto the ground.

An hour and a half later, Kai opened his eyes to find himself once more in his bedroom at the castle, Rachel right next to him, waiting nervously as the good doctor Luke was inspecting Kai.
"It's truly astonishing!" Doctor Luke exclaimed.
"What is it?" The Baron asked while nervously pacing around the room.
"There is no need to worry Baron. The Young Lord has only suffered a case of excessive Mana absorption. The Young Lord must have come into contact with an ancient artifact or mana-infused fruit. If a normal person were to consume it, there would not be much effect. However, the Young Lord has clearly been training his body recently, and rather aggressively in a short period of time it seems. Therefore, his body had become strong enough to hold a lot of mana compared to a normal person, yet he had not had time to absorb that mana from the surroundings. Therefore, when his body found a new source of mana, it immediately absorbed it all, resulting in the current situation." Luke continued.
"So, what you are saying is that… Kai just absorbed too much mana too quickly and so his body had to take a few hours of rest to get used to a large amount of mana? How much mana are we talking about exactly?" Baron Dread asked the doctor.
"Enough to be considered a Rank 1 External Arts User. That is if he learned an External Art to match his Rank."
'Oh, it seems that unknown energy the system was talking about was Mana.'

[Unknown Energy has been set as Mana]
[Scanning body for Mana]
[Mana detected]
[Traits of Mana have been discovered]
[The system can use Mana to accomplish tasks which involve interacting with the world]
[New features have been added which utilise mana to conduct:]
[The following tasks can be completed:]
[1. Conducting massive calculations]
[2. Completing tasks using calculations]
[3. Predicting the time it takes to complete a task]
[5. Scanning and Recording objects and events]
[6. Forcefully enter data into your mind. However, the more information it is, the longer it will take]
[Please note that body heat is used to power the system. Mana can be used to speed up the tasks]
[The following Tasks can only be completed by using Mana:]
[1. Scanning everything in a 2-meter radius]
[2. Scanning a particular object/creature within a 5-meter radius]
[3. Scanning the host]
'Huh… So I can use Mana to perform those extra functions… but they do not seem too useful…' Kai commented in his mind as he turned his focus from the voice in his mind to the Baron and doctor who were standing in front of him.
Slowly, he lifted up his body, and surprisingly, he felt incredibly light. It felt as though he had been living his whole life underwater, and all of a sudden he had been lifted out of the water.
"Kai? You are awake!" The Baron exclaimed as he turned his attention away from the doctor and back to Kai.
"Yes. And I feel amazing." Kai said before the Baron could ask him any questions.
'How much Mana do I have? And how much Mana will it take to use those last three functions?' Kai asked.

[It will take the host 1 unit of Mana to scan the host. It will cost 2 Mana to scan an object within 5 meters of the host. It will cost 5 Mana to scan everything 2m around the host.]
[Based on this unit system, the host currently has 12 Mana stored in the body. However, this number may differ from the actual amount of mana in the body. To get a comprehensive number, please scan the Host's body using Mana]
'Alright then, scan me'

[The Host has exactly 13 Mana in the body. Mana is accumulated from the surroundings at 1% of the Mana in the atmosphere per minute. Current Atmospheric Mana is 10. It will take 2.33 hours for Mana to recover completely from having none in the body. Currently, there is no method of increasing the Mana capacity of the body other than training. 14 Mana is the host's current maximum]
[Host also has a scar on his right arm, stretching from the palm all the way to the chest. However, this has been hidden from sight through unknown means]
Kai decided to ignore the last bit since he could not find any scar. It should be another thing where the System was wrong, just like how it was wrong for how long it would take Kai to recover.
