Yibo was asleep when there was a loud knocking on his door.

Yibo got up and opened and when he did he saw a very freaked-out Cheng over there.

Yibo's sleep vanished, and he let Cheng in, "What's wrong?"

Cheng immediately turned back, "Simon...your son..."

Yibo's eyes slightly widened, "What's wrong did something happen where is he..."

Yibo was about to leave but Cheng grabbed his hand and stopped him, " he is fine he is sleeping in my room."

"What is he doing in your room?"

Cheng yelled, "That does not matter god damnit."

Yibo was shocked by the sudden outburst, and Cheng took a deep breath, Your son gave me his book, and guess what it was blank but you what he did next he slit his hand made me drink his fucking blood, and then I can read the book!"

Yibo's eyes widened, as he saw Cheng rubbing his stomach, "It was nauseating...but that's not the point duke the point it..." Cheng lowered his voice and said slowly, very slowly as he came closer to Yibo, "Your son is a threat to this world." 

Yibo glared at him, "No he isn't."

Cheng laughed maniacally, "You know what...if he gets into the wrong hands he will be used if he cannot be manipulated he will be killed and that too very brutally...and you know what else...if someday he is not able to control his power if someday...he becomes evil then do you have any idea how much destruction he can cause?"

"I know."

Cheng closed his eyes, and sat down, "You should lock him up somewhere."

"My son is not a beast...that I need to lock him up."

Cheng glared at him, "Your son isn't but this world is duke, believe me, I have seen it..."Cheng said and suddenly there was that same insanity and madness in his eyes again, that same pain that seemed to have been eating Cheng alive.

"I have seen it, duke, I have seen it with my own eyes, if someday, even by mistake the cult of Mithras found about him then..."

Cheng visibly shivered and cowered back.

Yibo saw the pure horror on Cheng's face, all these years Yibo had always thought that what must Cheng have gone through to change so much so be scared so much...and after what Zhan told him Yibo has a very vague idea, a slight doubt that he wishes never becomes true.

Yibo grabbed his hand and made him sit on the bed while he sat in front of him and looked at him with hope, "Cheng...my son is special...and he is dying."

Cheng looked at him while Yibo continued, "I took him to the temple of Nirvana, where he got that book from, and from there we found out that, his body is weak and cannot sustain his strong soul...he has to train...his body needs to get stronger or else...he will perish...please Cheng as a father I am begging you."

Cheng got up, "Duke..."

"You used to call me brother..."

"When you used to trust me...but the point is not that...there are people much much better than me...and..."

Yibo stopped him, "See that's where you are wrong Cheng but let's not talk about it...let's talk about why you...well because I trust you because Simon trust you...

If I go somewhere else to hire a teacher I can't trust them, I cannot hand over my son to just anyone not when royalty, nobility, and temple are against me, what if some spy comes after my son.

What if someone tries to assassinate him, to someone my worry would be too much but you know Simon's secret so you must understand why I am being so paranoid. I have the responsibility of the dukedom I cannot abandon them your brother and sister have a responsibility too.

You are the only one left...please..."

Cheng clenched his fists but Yibo said again, "You said that he is a threat to this world right? but he can be a blessing too if you train him, then...he can help the people, our people..."

"This is a huge responsibility for a maniac like me."

"I would say that this is a perfect opportunity for you to make a comeback."

Cheng looked at him and scoffed, "Make a comeback? you really believe that I can make a comeback after what I did?"

Yibo moved forward and looked straight in his eye, "I believe that you can come back and I and everyone want you to come back and hunt down the cult of Mithras..."

Cheng was baffled, "You believe me?"

"Yes, we do." A third voice was heard in the room and there was Zhan at the door with a smile he came forwards and said, "We do believe you."

Cheng looked at him, "Did you also know about..."

Zhan smiled, "My back wound is all healed and I am alive thanks to that brat." 

Yibo sighed, "I am sorry Cheng for not believing you back then I really am..."

"I don't think that you believe me even now, at least not fully."

"Then how about you come back and make me believe? show me and make me believe it everything."

"How can I?"

Zhan spoke, "Brother don't you understand? you have a very great opportunity...a very great strength..." Zhan paused, "Your madness."

"My madness?"

Zhan nodded, "Use it,...use it an excuse, as a mask, as a disguise...as an opportunity...you can become our secret weapon..."

Cheng didn't say anything for some time before he spoke again, "I'll think about it."

With that, he was gone while Zhan and Yibo looked till he vanished from the sight.
