Context: ML has been rehearsing reasonable lines to move MC to become his lover, ends up messing it up and upsetting MC. This is slightly guesswork edited from MTL.

"Without a shred of patience, Qing Yun got up and walked to the desk in two strides, glaring at the head of Ningda's president. He (QY) then pressed his (ML) handsome face into the keyboard and rolled it.

"Hey!"

"Bang!" sounded the door closing as Qing Yun left, without any guilt on his conscience towards his boss.

Ning Qianyuan quietly rested on the keyboard, and full of grievances, read the second half of the sentence: "You can try to rely on me..."

However, no one was there to hear his soft concession."

And as MC gets increasingly powerful, the worlds rules and staying in character of the original matter less and less to him

And during the worlds there's ofc the ML following him around. I'm a bit torn about ML, can't say he's particularly interesting nor bad so meh ~

Ming Tan (?) He is MC's sword. Remember the one which helped him block the Heavenly Dao. But ML's original identity is not a sword. He is from another world, and in this world he came as MC's sword. He also is against the Heavenly Dao.

And the main thing is he gradually fell for our MC, but as a sword, he couldn't do much or express his feelings. So, when he sealed his memories to follow MC in various worlds, his thousands of years of feelings finally exploded.

I personally found it touching and logical, after all their are many stories where logic is lost when it comes to love, and this isn't far fetched.

Due to the body's limitations, MC is locked into his five/three year old mentality most of the time. The ML treats him completely as a child, but these memories are real: when the MC reverts to his real age/mentality, the affection he felt as a child toward the ML is a real part of his memories. This understandably upsets the MC a lot!!!! But it's basically the best and quickest way for the MC to become actually emotionally involved with the ML instead of treating him like a s*x toy. The ML is never disgusting toward the child self, and actually hates himself for being attracted to the older self and struggles with his feelings.

This is MTL, but as I understood it: the ML was originally a 'rules enforcer' with a system who would act as a protagonist. this system actually wanted to devour the ML, but he had managed to save up energy and protect himself from the system. Then he appeared to be roaming around? He became aware of the birth of a child that the Heavenly Dao was ''concerned'' about, ripping the child's soul into pieces and scattering them. the ML basically showed up occasionally to save the child, but became more and more involved.... somehow he became a spirit in the child's sword... this child is Qing Yun, the MC. So, the ML has actually been with the MC since he was young. As the MC's sword, he chased after the MC when the MC left the original world to heal his soul, but because his soul wasn't scattered, he could only force his way into the various worlds. Due the rules, he had to lock his own memories, and was shocked after his memory-less self actually got sexually involved with the child he was protecting!!!!! Then it happened again.... it's after the third arc that the ML basically gave up on himself and accepted that he'd fallen in love with the MC - that's the actual reason that he 'stole' the third world: deciding that he'd served his cause enough and was allowed to be selfish. Since he's very well aware of Qing Yun's backstory, he's extremely touched that Qing Yun came after him to save him instead of still being hell-bent on his own goals.

Although the MC has his nerves touched by knowing that the ML has something to do with 'protagonists', he basically unreservedly accepts the ML's identity. As he thinks several times! Since the ML provoked him, he can only be with the MC!

The ML also knows that the best way to get close to this extremely self-defensive person is to be dog-like hahaha, but he doesn't suffer and isn't dissatisfied being this way. Otherwise, how could his memory-less self successfully do it in so many worlds!!!

Since in the zombie arc we see how the ML is making his way to the MC's little heart and how the MC panics for fear of being betrayed again 💔 but the beauty of this arc is that the ML shows that no matter that his memories are sealed, he will still love and care for his beloved 😭💕.

This arc and the last arc are a roller coaster of emotions, I cried because at the end some problems that made the MC paranoid were fixed.... or rather they were clarified :')
