Before rebirth, he was the assistant of Mebius.

After checking into the nearest hotel, Ling Feng repeatedly promised not to leave secretly and to say something outside the bathroom every three minutes. Only then did Mebius agree to Ling Feng's request to temporarily untie the scarf. (People with poor physical fitness should not take a shower after being drunk.)

"Don't worry. I still have to go to the Fire Moth to get the Herrscher Core and the Key of God tomorrow. Why should I leave now?"

"Okay, Doctor, go take a shower. I'll wait here." Ling Feng promised Mobius at the bathroom door while sitting on a chair in front of the floor-to-ceiling window.

As the sound of running water came out from the bathroom, Ling Feng turned around in his chair and stared out the window at the stars that occasionally twinkled in the night sky.

Because he didn't really want to keep track of time, Ling Feng would only take the initiative to chat with Mebius in the bathroom whenever he remembered, so most of the time he would only say a few words when responding to the other party.

This situation lasted for more than forty minutes, until Mebius came out of the bathroom and quietly hugged Ling Feng from behind. Ling Feng then remembered that he seemed to have not spoken to him for five or six minutes.

"Oh! That really gave me a fright, Doctor."

"Stop pretending, little white mouse, you must have noticed it a long time ago, right?" Mebius said speechlessly.

"Haha~ I just don't want to spoil the Doctor's fun. By the way, Doctor, why are you only wearing a bath towel? Where are your pajamas?"

"...Tsk, are you serious? Little white mouse, of course the pajamas are in the bedroom of the research institute." Mobius's eyes fell on Ling Feng's forehead and he said with a worried look.

"Ah...I think so."

"But it doesn't matter. I'm here to do everything. It's just a pair of pajamas. Just sprinkle some water~"

"Then... Next, please welcome the great Ruler of Principle Ling Feng to show his might—"

As the middle school student's words finished, Ling Feng first clenched his left hand and placed it vertically in front of his body, raised his right hand, and spread his palm upwards, then raised his right hand to draw an arc and placed it diagonally in front of his body, while his clenched left hand was placed not far above his right hand, forming a parallel posture with his left hand.

"Puchi~ What...what are you doing?" Seeing Ling Feng doing such a funny and immature thing, Mebius covered his mouth tightly, but in the end he couldn't help laughing.

“It’s an important ceremony.”

"Okay, show up—"

After Ling Feng finished speaking, he snapped his fingers and a women's white ice silk pajamas appeared in his other hand.

"How is it?" Ling Feng asked.

"I don't like these slippery pajamas."

"But this touch feels really good. Doctor, please fulfill my little wish." Ling Feng held the pajamas in his hand and looked sincerely into Mebius' eyes and prayed.

"..."

"You have so many little wishes." Looking at this slightly informal pajamas, Mebius was a little reluctant, but seeing the other party's expectant look, she finally took a step back.

"...Hey~ Since you didn't break your promise, I'll do as you say this time. Just give it to me."

"Great--"

After taking the pajamas, Mebius said dissatisfiedly as he looked at Ling Feng who was still staring at him, ready to feast his eyes.

"…Why are you still staring at me? Go take a shower, or you'll sleep on the floor tonight."

"Good~"

Although he was somewhat unwilling, Ling Feng did not hesitate and immediately trotted into the bathroom.

After thoroughly washing off the smell on his body, Ling Feng, wearing pajamas also constructed using power, rushed out of the bathroom impatiently and pounced to the side of Mebius.

"Little white mouse, be quiet. It's almost twelve o'clock. Aren't you afraid that people downstairs will complain about us?" Mebius tapped Ling Feng's forehead with his index finger.

"Then I'll buy this hotel, and no one will bother us anymore."

"Oh, by the way, Doctor, I have another question for you... Just now in the restaurant, many Shesha scales appeared on the Doctor's legs, and his teeth became very sharp. Why is that?"

"How many scales?"

"They are in clusters, with the most at the thigh roots and only a few by the knees, but they are all very firm." Ling Feng answered truthfully.

"Klein told me about this before, but she only told me that the teeth would become sharper, and she didn't mention the scales... But don't worry, this is normal. It won't be long after you wake up, and they will completely disappear."

"Really? Let me see..." Before asking the other party's opinion, Ling Feng suddenly lifted the quilt and looked straight at Mebius' thigh.

"…Huh? Really no more."

Seeing this, Mebius pointed at Ling Feng's forehead with his index finger, forcibly pushed his gaze away, and then covered him with the quilt again.

"Have you seen enough, little white mouse?"

After being pushed away, Ling Feng no longer pretended, but stated his intentions and expressed his dissatisfaction very straightforwardly.

"That's not enough. How come the doctor has become so stingy..."

After pushing Ling Feng away again, Mebius asked.

"Not yet, little white mouse... before that, you have to agree to one condition of mine."

"Doctor, don't try to bait me. I'll agree to anything."

"Hey~ How can a verbal agreement count? Why don't you sign it?" Mebius supported Ling Feng's forehead and pushed him away from him again.

"What's there to sign...what a hassle." After being pushed away, Ling Feng lay on the bed and muttered to Mobius who was looking at him.

"Since it's too troublesome, just record it."

"You must swear to never betray me, never leave me, and never abandon the other person before me for any reason or on any grounds."

"Okay, okay, I swear."

"I, Ling Feng, will never betray Dr. Mobius and will never leave..."

After recording Ling Feng's entire oath, Mebius lifted the quilt with satisfaction and let the other party in.

Familiar human breath, familiar life energy, familiar touch, and a slightly cold waist.

Feeling everything about each other, time seemed to go back to that night more than a year ago, the first and only night when the two of them were "honest with each other" and entrusted everything to each other.

"It turns out that time flies so fast. It turns out that I have ignored the doctor for so long." Ling Feng kept talking to himself in his heart as he nestled in the other's arms.

"PhD……"

"Hmm? What's wrong? Little white mouse."

"... Right now, okay? Doctor, if I don't do this, I might regret it very much tomorrow." Ling Feng raised his head and looked into the other's eyes sincerely.

"Yeah~ Of course, I just promised you."
