In the instant it finished speaking, it suddenly broke free from Zero’s hand and ran to the ground. The big black mouse’s body size suddenly expanded, growing to a five-meter-long big black mouse, transforming in the blink of an eye.

Its body was no longer shaped like a black coal ball. It had a mouse head, mouse tail, and four healthy limbs. The tail was still slender, but much longer. Then it started running in the direction of the sound.

While running, its size continued to increase. Finally, it grew into a terrifying behemoth hundreds of meters long and dozens of meters tall!

Chen Xing was dumbfounded looking at its figure running away: How can something this powerful act like a fool usually?

Zero was so shocked her little jaw dropped! She rubbed her eyes in disbelief and looked again: “Such a huge… mouse!”

Chen Xing chuckled and picked her up. Then he followed closely behind the big black mouse.

Now it seemed that this black mouse was truly the origin beast of this world, evident from its size alone. It was larger than ordinary A-level spirit beasts by a wide margin. But the strange thing was, why did this black mouse, so powerful, come looking for him?

The big black mouse was fast, but Chen Xing was faster. He directly carried Zero and jumped onto its back!

“Wow… it’s so high!” Zero exclaimed and then lowered her head, looking at the demons below that appeared like ants, finding it very interesting.

Seeing her so happy, Chen Xing gently put her down and let her stand on the back of the big black mouse. After the big black mouse grew larger, its fur extended well above Zero’s small head.

Chen Xing took out a knife and shaved the area they were standing on, making it smooth and flat.

The big black mouse felt a chill on its back and turned its head, feeling like swearing!

If it weren’t for being unable to defeat these two and needing their help, it would have definitely eaten this pair of jerky lovers!

But now the most crucial thing was to save its own wife!

“Hehe…” Little Zero hopped on the back of the big mouse. The flesh on its back was soft and bouncy, like a trampoline, giving away that it had probably eaten a lot.

“Do you like it?” Chen Xing asked her with a smile.

“Yeah~ It’s so much fun!” Little Zero replied.

“Do you want to take it home as a pet?”

The big black mouse: ????

“Well… sure! That’s great! Love you~” Zero suddenly bounced off its back and flew straight towards Chen Xing in the air, with a big smile on her face and arms wide open, like a flying bird.

Chen Xing caught her with a laugh, and Zero was extremely happy!

“Hehe~ So much fun!” She exclaimed.

Chen Xing kissed her and said softly, “Let me show you something even more fun!”

“Yeah!” Zero replied.

After that, Chen Xing suddenly stomped.

“Thud~!” The big black mouse happened to be in mid-air, and its several hundred meters long body was directly stomped to the ground by Chen Xing!

It looked puzzled.

What the heck? What just happened!?

Meanwhile, Chen Xing had already flown into the sky.

As soon as the big black mouse got up and looked up, Zero screamed, and Chen Xing had already embraced her and landed back on the ground.

The big black mouse shook its body and quickly stabilized its posture, thinking that Chen Xing had attacked it. It immediately arched its back, ready to defend against the attack.

However, Chen Xing was merely free-falling. When he stepped on its back, he bounced up again with a “duang~.”

“Wow, don’t do that! I’m scared…”

After bouncing for a while, Zero exclaimed, “Wu Hu~ So much fun!”

“Giggle…”

Little Zero was having so much fun.

The big black mouse was speechless, thinking that they were simply not human!

“Wife!” The big black mouse leaped into the sky, blocking the moon in the sky.

Its eyes flashed with red light, and its sharp teeth were exposed, looking very frightening.

The demons on the ground showed fierce and ferocious expressions, but when they saw Chen Xing and Zero standing on its back the next moment, they were surprised and said, “It turns out to be the Demon King’s mount!”

At this moment, the two big black mice were surrounded by the demons.

Though the body size of the other mouse was also around a hundred meters, it clearly lacked the imposing aura of the one under Chen Xing’s feet. The female mouse saw the big mouse under Chen Xing’s foot and exclaimed in surprise, “Squeak, squeak?” (Lord Dian’er?)

The big black mouse also froze for a moment and replied, “Xiao Cui!? Oh my god! My Xiao Cui! I finally found you!”

While speaking, it landed heavily on the ground with a muffled sound. It glared fiercely at the surrounding demons, and the demons glared back with the same ferocious expression. If it weren’t for Chen Xing standing on its back, it would have charged forward and attacked. It was hard to say who would win.

The female mouse across from it made another sound, “Squeak, squeak?” (How did you get here!?)

The big black mouse excitedly said, “I heard you calling for your husband from afar! So, I came to rescue you! My Xiao Cui, I missed you so much!”

Xiao Cui rolled her big black eyes and looked at the big mouse standing beside her. She said, “Squeak, squeak…” (I was calling for my husband! Not you, Lord Dian’er!)

“Huh?” The big black mouse (Lord Dian’er) looked at the mouse beside its Xiao Cui. It was a small and skinny mouse, about two-thirds of its size. Lord Dian’er was embarrassed and didn’t know what to say.

Xiao Cui spoke again, “Squeak, squeak…” (Let’s end our relationship here, Lord Dian’er. You… are too small.)

Lord Dian’er: ???? “I’m small?! Am I not bigger than him?!”

Chen Xing looked at the two mice with a weird expression. Xiao Cui spoke in mouse language, and Lord Dian’er spoke in human language, so he could only understand parts of their conversation and felt they were talking about something strange.

Seeing that Lord Dian’er misunderstood, Xiao Cui quickly explained, “Squeak, squeak…” (I meant your size is too small in your original form! I… like my mouse more imposing.)

Xiao Cui was referring to Lord Dian’er’s original black coal-like appearance. While Xiao Cui was a proper two-meter-long big mouse, Lord Dian’er was just a black coal-like ball about the size of a palm. It had turned into this form due to an accidental mutation.

“Squeak, squeak…” ( Moreover, we are speaking mouse language, and you are speaking human language… even during that intimate moment, you were speaking human language. It’s really terrifying. )

Lord Dian’er: “…”

While Lord Dian’er was speechless, Chen Xing had already jumped down from its back, carrying Zero in his arms.

“All hail the Demon King! All hail the familiar!” All the surrounding demons immediately knelt down!

This scene shocked Xiao Cui and her little lover. They hadn’t expected that the young boy and girl in front of them were actually the masters of these demons!

Chen Xing nodded without saying a word while carrying Zero in his arms.

Zero didn’t pay much attention to it. With her beautiful eyes wide open, she looked at the two big black mice that had just appeared.

“Um… are they a couple too?” She asked.

Upon hearing this, Lord Dian’er quickly retorted, “No! Xiao Cui and I are the couple! I will eat that damn mouse right away for daring to steal my wife!”

Xiao Cui realized the situation and quickly pleaded, “Squeak, squeak…” ( Lord Dian’er… can you spare us? We truly love each other. They say one day as a couple is a hundred days of gratitude. Please, have mercy! )

Lord Dian’er paused upon hearing this and muttered, “One day as a couple is a hundred days of gratitude?”

Upon finishing his words, tears actually appeared in his eyes!

Suddenly, his hundred-meter-long body disappeared from sight. A small black coal-like ball appeared in the air.

“Wuwaa!…”

The mighty mouse shed tears!

After landing on the ground, it bounced several times and finally crouched on the ground, crying loudly. Its way of shedding tears was different from other creatures. Two tears flowed directly out of its big eyes like water jets, looking a bit funny.

However, Zero couldn’t laugh.

“Um… Chen Xing, what happened to the big black mouse?” Zero couldn’t understand mouse language and felt a bit sorry seeing Lord Dian’er so sad.

Chen Xing also couldn’t understand and casually said, “I don’t know, maybe someone stole its wife.”

“Poof…” That sentence was like a knife piercing through Lord Dian’er’s heart.

After hearing it, Zero pursed her lips and softly said, “Um… the big black mouse seems really pitiful…”

“Poof!” Another knife pierced through Lord Dian’er’s heart.

“Wuwaa!!!”

The mighty male mouse crying became even more heart-wrenching.
