The reason why the remnant spirit didn't hesitate to become Leo's target was that it would not deal any damage to him.
'As long as he activated the weapon skill in front of me, I can track where the Apostle Seal is disappearing to.'
The remnant spirit was hoping that the Apostle Seal on Leo should not disappear after the activation. Even if it does, he could find out why it was disappearing.
Previously, when he was recharging his energy, the remnant spirit thought a lot about it; however, he didn't get a satisfactory answer for why the Apostle Seal on Leo disappeared without a trace.
So, the remnant spirit wanted to see for himself whether the same thing as before happens or not. If that happens, he could have an easy time finding the reason behind it.
'Having a powerful apostle is good but if that apostle has so many secrets it is not a good thing. Anyway, once he becomes my temporary apostle, I can take my own time finding all his secrets before making him a permanent apostle.'
The remnant spirit had his own planning as he asked Leo, <Participant Leo, go on and attack me with the weapon skill>
'He took the bait.'
On the other hand, Leo revealed an evil smile behind his blood-coloured mask and hurriedly activated his new system ability.
[Spirit Swallowing Ability]
'Ding,
The host activated the [Spirit Swallowing Ability]. Please choose the spirit you want to swallow.
Along with the system notification, a pop-up notification appeared above the remnant spirit's head.
[Energy - 50 percent, Swallowing Success Rate: 50 percent].
'50 percent? I have to weaken it further.'
Just like how the pop-up notifications appeared for the [Seal Swallowing Abilitiy], the same type of pop-up notifications appeared, informing the success rate.
According to the ability's information, the weaker the spirit, the higher the success rate.
Therefore, Leo decided to weaken the remnant spirit even further before using the [Spirit Swallowing Ability].
<What are you waiting for? Use it and take the last reward from the [Diamond Section] before leaving the [Treasure Land]>
From the distance, the remnant spirit was urging Leo to activate the weapon skill so that all his doubts would be cleared.
"I hope I won't kill you with it."
Leo said those words and shouted out loud,
[Abyssal Demon Sword - Abyss Blast]
Leo activated the weapon skill to let the remnant spirit's guard down and soon a black-coloured mist spread around Leo and his followers.
'This brat thinks that he can kill me with Abyss Blast?'
Even though he was just a remnant spirit, the Abyssal Demon God was still a God-like entity. Moreover, it was a weapon skill that he was very familiar with. So, he was not worried too much about it.
'Ding,
The special supreme seal has been engraved on the host's body. Please remove it as soon as possible.
'[Seal Swallowing Ability]'
Just as the apostle seal appeared on his body, the system sent a notification to Leo, who in turn, activated the [Seal Swallowing Ability] to devour it.
'Damn it...what happened? I clearly saw the apostle seal appear on his body.'
As for the remnant spirit, he easily dodged the [Abyssal Blast] and entirely focused on Leo's body.
He saw the apostle seal appear and in less than a second, it disappeared right in front of his eyes.
<Once again. Activate the weapon skill>
Without wasting any time, the remnant spirit locked the Abyssal Demon Sword again and the only way to unlock it was by using the weapon skill.
So, he asked Leo to do it again.
"Why?"
However, Leo didn't do it instantly, as he checked the information on the Abyssal Demon Sword and thought, 'As I expected, he locked it again. I wonder how much of his energy was consumed to do this.'
At the same time, he used the basic effect of the [Spirit Swallowing Ability] to check the energy spent by the remnant spirit.
[Energy - 35 percent, Swallowing Success Rate: 65 percent].
'He used 15 percent of his energy in locking the Abyssal Demon Sword. I think I can use it one more time.'
Even though the success rate reached 65 percent, Leo didn't want to take any risk because the other party was not a regular entity.
'If I failed and let the remnant spirit escape from here, the Abyssal Demon God would know everything about me. I can't let that happen.'
Currently, Leo was still a supreme rank hero and he could not even fight a legend rank hero, not to mention, a god entity.
'If the Abyssal Demon God decided to kill me, no one could stop him.'
With that thought in mind, Leo waited for the remnant spirit's reply.
<If I ask you to do it, then do it. Why do you ask so many questions, you b*stard>
The remnant spirit was so annoyed and he no longer bothered about his image in front of Leo.
He wanted to find out what was happening to his Apostle Seal and the only way to find out about it was by repeating it.
'He is no longer hiding it.'
Leo's followers standing behind Leo were scared when they saw the evil look on the remnant spirit's face; however, Leo was calm and revealed a cold smile.
"Okay then."
Since he could swallow the apostle seal in less than a second, Leo didn't have any problem in using it.
'Moreover, after devouring 100 special supreme slaves, there will be some kind of upgrade in that ability. So, I can swallow it as many times as possible.'
Soon, Leo and the remnant spirit repeated the same set of actions two times, leaving the remnant spirit's energy at five percent and his success rate at 95 percent.
'It looks like I can finally swallow this b*stard.'
Leo decided to not waste any time and devour the remnant spirit.
'Something is definitely off about this brat. I think I have to use my final move.'
The remnant spirit on the other hand looked weak; however, his determination to find where his apostle seal was disappearing, hadn't gone yet.
Hence, he decided to use one final move that he didn't wish to use.
'So, be it. I might die but the main body will know that there is a potential apostle in this world and during the world assessment, he will arrive first compared to the other b*stards.'
With that thought in mind, the remnant spirit disappeared from his place and appeared behind Leo.
<Brat, you got a huge potential to become my apostle; however, you leave me with no chance>
The remnant spirit's eerie voice resounded beside Leo's ears and it continued, <What are you doing with my apostle seal? How can it disappear?>
The remnant spirit wrapped his arm around Leo's neck and squeezed it while asking what he was hiding.
"You...know....you...can't...kill...me...inside....the...[Treasure Land]?"
Leo didn't expect that the remnant spirit would try to kill him so openly because the remnant spirits have their own set of rules and the main rule was not to kill the participants that enter the [Treasure Land].
Of course, they could use other participants to kill a particular participant but they could not kill the participants themselves.
<I am prepared to die along with you. So, if you tell me what you are hiding, we both can live>
