Looking at the little dog he had healed, Buu was overjoyed. He happily exclaimed, "Buu did a good deed, Buu did a good deed."
This was something that Goku's family had been teaching Buu all along. After bringing Buu home, they took turns teaching him, using the same books they had used to educate Goten when he was younger. They taught Buu what he could and couldn't do.
Buu had a particularly deep impression of doing good deeds.
After healing the little dog's injured front leg, Buu was extremely happy and delighted.
The little dog circled around Buu a few times and then started running towards the distance.
Buu was originally planning to wait outside the shop for Goku to come out, but when the dog realized that Buu wasn't following, it turned back and came to Buu's front, biting his boot and pulling him along.
Buu curiously pointed at himself and asked, "Do you want me to follow you?"
The little dog seemed to understand Buu's words and immediately wagged its tail vigorously, barking excitedly several times.
Buu didn't think too much about it, or perhaps he didn't understand much. When the dog called him, he followed behind it, heading towards the distant city.
The dog led Buu to a remote corner of the city, all the way to a secluded spot.
The dog barked loudly towards the dark alley, and although it was small, it seemed to know that someone was behind it, so its momentum was very strong.
Soon, low growls emerged from the alley, and after a while, three large dogs with dark fur and dull eyes emerged from the dimly lit alley.
They growled menacingly, their fierce eyes fixed on Buu and the little dog.
The little dog was startled by the appearance of these three dogs and immediately hid behind Buu, but it didn't run far. It continued to bark and provoke the three large dogs.
As the little dog kept provoking them, the three large dogs couldn't take it anymore. They leaped towards Buu, their mouths wide open, and bit into Buu's body.
However, Buu paid no attention to the dogs' attacks, thinking they were playing with him. Their bites didn't hurt him at all.
It should be noted that Buu had been playing and messing around with Goku, Gohan, and Goten at their home for the past few days.
The pain caused by Goku's family's attacks was much more intense than the pain caused by these few dogs.
Buu thought these dogs also wanted to play a fighting game with him, so he reacted as he did when playing with Goku's family. He swung his arm and spun around, and the dogs that were still hanging on him were flung off, slamming into the wall.
The physical strength of these stray dogs couldn't compare to Goku's family. After Buu used the same force he used against Goku's family, the dogs that were smashed into the wall whimpered a few times and then became silent.
Seeing that he had killed the dogs, Buu was shocked. Goku had repeatedly warned him not to kill anyone, but now he had taken a life.
Of course, this was also because Buu's simple wisdom couldn't distinguish between humans and dogs. In his simple mind, anything with life could be considered a person.
Buu quickly went forward and checked the three dogs, and upon confirming that they were indeed lifeless, he became a little lost.
In his panic, Buu randomly chose a direction and ran out, and the little dog, seeing Buu running, immediately followed.
Buu ran to a mountainous area outside the city and sat dejectedly on a hilltop, staring into the distance. He muttered to himself, "It wasn't intentional, it wasn't intentional..."
The little dog had been playing around Buu, but when it realized that Buu didn't want to play, it immediately ran to the distance and started chasing butterflies in the air, playing by itself.
Just then, a gunshot rang out, and a bullet hit the little dog in mid-air with a "pop" sound.
A trail of crimson blood spattered from the little dog's body, staining a patch of grass.
At the same time, two voices could be heard in the distance. One of them, trying to flatter the other, said, "Young Master, you are truly amazing. You hit the target with just one shot."
Buu was furious when he saw the little dog being shot, especially since he had killed three dogs earlier. Buu's heart was filled with both self-reproach and anger, and this state of mind caused Buu to undergo a transformation similar to the original story.
The good and evil within Buu began to split. His head started to hurt, and he felt a massive energy separating within him. He struggled to endure it, trying to prevent the other half of his body from separating.
Just then, Buu heard the little dog's weak whimper. Bearing the pain, he walked over with difficulty and used his magic to save the little dog.
The two men who had killed the little dog had already driven over from a distance. The gunman in the passenger seat was surprised to see his prey still alive and jumping around, thinking he had missed his shot.
Remembering the praise from his bodyguard, the young master-like man became embarrassed and angry. "Watch me shoot and kill it," he said.
He raised his gun and fired again, but Buu quickly moved to block the bullet.
Buu glared at them angrily and roared, causing the bullet embedded in his body to bounce back and hit the car's engine compartment.
The moving car immediately flipped over. It was clear that Buu was still following Goku's teachings and not harming humans.
However, the two villains were not willing to accept Buu's mercy. They got out of the car and started firing countless bullets at Buu.
Buu tightly protected the little dog under his body, and the bullets hit him one after another.
The anger of being unable to fight back finally triggered the power within Buu. Instantly, countless breaths emerged from his pores, gathering in the air above him.
Due to the sin and evil in humans, Evil Buu still split from him.
At that moment, Goku had just finished a transaction with his boss and was counting the money. In the instant that Evil Buu split off, all the warriors on Earth, including Goku, John Doe, and Vegeta, felt this massive energy.
"Isn't this Buu's energy? How did it become so evil?" Android 18 asked, hugging Axel Doe.
John Doe looked towards the direction where Evil Buu had appeared and said, "I don't know either. Something unexpected must have happened, causing Buu to turn evil."
"You and your son stay at home. If the situation becomes unfavorable, take him to the Temple of the Gods, and I'll go see what's happening."
After instructing Android 18 and Axel Doe, John Doe used Instant Transmission to appear at the location where Evil Buu had emerged.
