The man that Sin-ui spared was called Ain, he was a very good friend to him in his past life but he would just be labled crazy if he says he came back from the future so he just said, "I have the ability to see those who are pure.".
He continues and says, "You are one of the rare people who has 100%." he knew if he said this there would be a chance for Ain to believe him since that ability was called "Judgment" which holy classes have.
Then Ain raises his spear at him and says, "So? That still doesn't explain why you spared me." Sin-ui sighed and then sent him a friend request and said, "Well, I want to be friends with you if you are that pure.".
Sin-ui said as he was getting ready to charge at him, Ain became terrified because he already watched him kill multiple people without breaking a sweat but then he chuckles and says, "Sure." as he stabs himself.
When Sin-ui saw this he started to chuckle and then remember the first time he met Ain and he didn't lie either in his past life, Ain became a Paladin Spear Man which was a rare class but he was just used.
So he wanted to change Ain's life for the better and now he was being transported to the next floor, he sighed but then he saw a notification saying that Ain had accepted his friend request and then he smiled a bit.
After that he was now on the tenth floor and he was given a 10 hour rest before the test actually started and he was now really happy meeting Ain again but then he remembered that he had rewards to collect.
[Ding! The Player "Sin-ui" has unlocked the achievements "100 In A Row!", "No Breaks" and "Ultimate Challenger!"]
The 100 In A Row achievement boosted Sin-ui's stats by 25%, the No Breaks achievement increased Sin-ui's recover speed in everything he has by 100% and the Ultimate Challenger increased loot by 50% against fights against opponents.
He was really happy with the achievements but now he was going to check the rewards and when he checked them he re-equiped everything since it was removed when he did the challenges before.
Then he saw he gained three items but they were all mythic rank, when he saw them he smiled greatly but he knew the tower wouldn't give him overpowered things at the trial floors of the tower.
Sin-ui then appraised each item and the first item he had was called, "Extra Mana Heart" it was a one use item but it was extremely hard to find and it will create another mana heart for you if you ate it.
So then he smiled as he copied it's ability then ate it as well and now he had three mana hearts which increased his mana greatly, he was a bit sad he didn't get everything he wanted on the seventh floor though.
Since he was a bit rushed by Cho but he knew that there was a way to get back to the trial floors among the higher floors so he ignored it for now and appraised the second item that he got as his reward.
It was called "Dual Energy Core" when he saw it he was immediately surprised and he couldn't believe he got this item because in the tower there are many different types of energies and one of them is mana.
But the tower only allows one person to have one type of energy but with this item he could have another and with his ability he can have three energies in his body he was smiling greatly as he copied it's ability and ate it as well.
After eating and copying it's ability he checked it out and saw that he now had to empty cores that he could fill with two more energies than before so he was really excited about this development and started thinking of what energies he should get.
Then he remembered he still had one more item to get and so he was excited to see what it was but when he saw it, it was just a key but the color looked similar to the tower and it was just called "@&$@&".
When he saw it he put it away because he couldn't copy it or use it right now since it's most likely owned by the rower but he was wondering why it was given as a reward if he couldn't even use it.
He didn't mind that for now and just said, "Skip rest." as he said that the resting area he was staying at started to suddenly disappear and then thebplace around him started changing into a full arena.
The 10th floor of the tower was a boss fight and the boss would depend on the user and the stronger the boss you fight the better the rewards and so it was like the 9th floor with the tournament and it's challenges.
[Ding! Would Player "Sin-ui" like to challenge Easy, Medium or Hard?]
Sin-ui chuckled as he heard the choices and said, "I choose the Abysmal difficulty." he smiled as the arena changed into a darker color and it suddenly turned dark as a person from the future he knew things other did not.
So he already knew that there were loads of difficulties other than the three that were given by the system, there were some easier and some harder and Sin-ui chose the hardest level that was found by the players in the tower.
Suddenly a dark figure appearwd in front of Sin-ui as it was transported by the tower and when he appraised it, it was a demon called "Glevion" which was ranked at the 100s among the demon realm.
Glevion chuckled and said with sinister tone, "I didn't expect that a player would find this feature so soon..." he said as he charged at Sin-ui with insane speed, Sin-ui just chuckles as he activates Herme's ability.
He moved at the speed that even Glevion couldn't see and said, "You should know the power of your opponent before you attack." and then he activated Wrath's authority to it's full power and then he was burning in pure red flames.
When Glevion saw this he said, "That's Lord Wrath' Authori-" Sin-ui used mana along with his magic blast ability as he blew up Glevion into mere dust without flinching and the battle ended really quickly.
[Ding! The Tower Administrator asks, "WHY DO YOU HAVE MY POWER?"]
Sin-ui chuckles as he walks around and says, "I don't just have your power Wrath, I thought you guys would've seen it the first time I used it but I was able to hold back pretty well for you guys to not be able to sense it yet.".
He continues and says, "But I guess you guys aren't blind when I use your authority at it's full power." he stops walking and grins, he looks up to the sky where he knew the administrators were watching him from.
Then he says, "But what can you do? That's not a rule made by the tower and you can't punish me for anything.", he said as he smiled slightly as the sins couldn't do anything about him for now.
