Yin-Yang Union Physique

Ethan had the urge to save the Assassin. But he didn't do anything. After all, that Assassin tried to kill him twice.

The first time, he managed to escape.

But the second time, he was trapped by the Assassin successfully. If it weren't for those two siblings who the elder killed from the Dark Grimm Grotto to interfere, the Assassin would have killed him successfully. He would have been dead by now.

So, Ethan thought that the Assassin was getting what he deserved. How many people did he kill in his life so far? He is getting what he deserves.

But then again, he thought that, even though the Assassin is someone who killed people for fun, then again, he killed only those people who were part of his professional targets. Even though in Ethan's point of view, it was an inhumane act, he didn't kill anyone else who was not part of his targets.

Especially, he didn't kill those people who lost their family members at his hands even when they came for revenge. Those two siblings were the best examples.

Even after they targeted the Assassin multiple times, the Assassin didn't do anything to them. Because the Assassin was sensible enough to understand that the two siblings came to kill them because he killed their father first.

Even if Ethan wanted to save the Assassin, he knew that he had to first save the Assassin from the Essence Devouring Array. Even if he managed to save the Assassin somehow, he had to escape from those terrifying people who were at the later stages of the Physique Strengthening Stage.

Even if he managed to escape from them somehow, how could he manage to escape from the pursuit of that terrifying Spiritual Roots Cleansing Stage Expert?

He is just a cultivator who is at the Elementary Stage. There is no way he could save the Assassin and escape from the pursuit of the Spiritual Roots Cleansing Stage Expert so easily. The chances of his failure are very high.

Moreover, the Assassin was someone who tried to kill him twice. There is no way he would put his life in danger for someone who tried to kill him, right?

But then when he looked at how these people from Dark Grimm Grotto were sucking all the cultivation the Assassin accumulated over the years and torturing him for just his denial of their proposal( Of course, it was a forced one), he felt disgusted with their methods.

Moreover, they were simply enjoying his shrill shouts. How could they find fun in all this?

'I read this kind of enjoyment only in the novels on earth. But I didn't feel anything when I was reading. But now that I'm witnessing everything personally with my own eyes, it simply feels disgusting.'

Damn! It sucks! What can I do?

Ethan was feeling helpless. But he couldn't find any way to save him.

"System! What are my chances of saving the Assassin?"

Ethan couldn't help but ask his most reliable source.

[The User's request has been acknowledged]

[Calculating the User's chances based on the User's possible opponents' strength]

[Calculation completed]

[The User's chances of saving the Assassin are: 0.01%]

0.01%!

When Ethan looked at this result, he had the urge to vomit. He was pretty sure that his chances were very slim. But he never thought that, his chances were practically nothing.

'Why did you even give that 0.01 %? Are you trying to encourage me? Or were you trying to consolidate me with that number?'

Ethan couldn't help but curse within his heart. But then, he took the warning of the System very seriously. But when he looked at the sinister smiles on the faces of those people from the Dark Grimm Grotto, he couldn't help but have other thoughts.

Sigh!

After sighing, Ethan gave a command, "System! Give me the safest way to save the Assassin."

No matter what kind of person the Assassin is, he is not completely heartless. Ethan could understand that much. He couldn't bear to see the horrible thing happening in front of his eyes. If he had to choose between the two parties, then he would choose the Assassin without any hesitation.

Moreover, he was curious about Kevin Walker for whom this Assassin was ready to give his life without any hesitation. And most importantly, why exactly these people from the Dark Grimm Grotto were targeting them in the first place?

And that Elder from the Dark Grimm Grotto said that their purpose will remain incomplete without capturing both the Assassin and Kevin Walker. So, what exactly is the story behind all this?

[Description: The Assassin is detected to have the Yin element Physique which is part of the Yin-Yang Union Physique. The Yin-Yang Union Physique is very rare and incredible. It appears very rarely in the world. The chances of their appearance are very slim. It appears only within identical twins. Even within identical twins, its appearance is very rare to the point of nonexistent. The people with the Yin-Yang Union Physique can prove terrifying and lethal as they progress in their cultivation. Among the two identical twin siblings, one of them will have a Yin Physique and the other twin will have a Yang Physique. But their true potential will be unleashed only when they are together.]

...

Ethan was speechless. He asked the System for the safest way to save the Assassin. Instead of replying accordingly, the System went and gave him a mission.

Ethan took 15 seconds to calm himself down. Right now, it is not the time for cursing. It won't help him.

Then he looked at the quest description. From the description, he understood that, for the Yin-Yang Union Physique to work properly, there need to be two twins to stay together.

According to the description, the Assassin has the Yin Physique. Then, his twin brother should have the Yang Physique.

Suddenly, something struck Ethan's mind.

That old man from the Dark Grimm Grotto said that their objective would remain incomplete even if a single member among Kevin Walker and the Assassin were missing. Only when they capture both of them, their mission will have some meaning.

Moreover, it has similarities with what was mentioned in the System's description.

If that is the case, then Kevin Walker might be the one with the Yang Physique. Since the Assassin has a Yin Physique, it adds weight to his analysis.

If that is the case....

Kevin Walker should be that Assassin's twin brother.
