After a few weeks of following the bull and studying it's behaviour and fighting pattern. Merlin decided that he was ready to take it on.
'I've made enough preparations. It's time to act.'
Without wasting any more time, Merlin pulled out a stack of papers covered with seals. He then applied the spell " shadow viel " to the paper, moving it slowly through the air to draw closer to the beast. After reaching near to the beasts neck, he activated his chakra, resulting in an explosion, and purple gas started to emanate from it.
'Wizards are different from shinobi; they are naturally better than shinobi at manipulating energy. I can control the chakra to lift any object below 5 kg. Now that the sedative gas is released, it will soon take effect.' Bringing his hands together, he made a seal of rat, boar, dog, and horse, creating a clone similar to him. Soon, the clone charged against the bull while forming a hand seal. Just as the clone reached near it's head, the clone exploded into electric bolt to paralyze the beast.
Casting 'Breeze Lift' on himself, Merlin flew towards the huge bull, trying to get its attention. Over the past few months of practice, Merlin had been able to fly at low altitudes without any difficulty. As he caught the attention of the mad bull, he started flying towards the north of the forest.
As he flew, the bull began to follow its attacker. Soon, as the bull caught up with him, seeing this Merlin showed a wicked smile on his face. Just as the bull was about to reach him, the ground beneath it split open, causing it to fall into a deep pit. As Merlin approached the pit, he saw the bull tried to keep its concious awake.
"I need to perform a blood sacrifice; if I wait further, it might regain its strength," Merlin said to himself. He activated the magic circle that had already been prepared. Soon, a barrier formed around the huge bull, restraining it. After completing the sacrifice, the life essence of the bull was formed. Consuming the blood, he found out his chakra level increased. "Compared to animals without chakra, the improvement is more noticeable. If I can perform more sacrifices on chakra-activated creatures, I would soon have the chakra quantity to advance to the second tier wizard apprentice."

"Merlin, I saw you completed your work for today. Why don't you have dinner with us?" Grandma asked.
"Thanks, Grandma. I will be here for dinner," Merlin replied.
After Merlin started working in the antique shop, he became close to the elderly couple, and they treated him as their own grandchild. Merlin also found out that the couple had a son who went on a shinobi mission but never came back.
At the dinner table, a child and the elderly couple could be seen chatting happily.
" Hagiri did you hear that the Third Hoshikage announced to stop the use star to train Ninja."
" Finally the evil practice is stopped. How many young children did we lose because of that terrible practice."
"Grandpa , what is evil practice you talked about " curiously Merlin asked.
"Merlin, did you know the village was formed after a star fell in the village? And the first Hoshikage developed a method to harness the power of the star to train shinobi. However, many lives were lost, and even if successful, they only lived up to 30 years maximum. Now the third Hoshikage has stopped the method," replied Grandpa Kaede.
Hearing about the star stone, Merlin showed great interest. "Once I reach senior apprentice wizard, I can check it out," he thought to himself.
After finishing dinner, Merlin left the couple. Walking in the night, Merlin decided that starting from tomorrow, he needed to increase his hunt.
Time skip of 2 year
"After two year of hunting, my chakra quantity finally reached its limit. It was hard to find chakra-mutated animals; after all, before the Warring States Period, shinobi were exterminating the mutated monsters for mankind's peace. When I become an official wizard, I will collect the alive monsters to breed. If all of them went extinct, it could cause trouble for me."
"Well, my chakra quantity has reached the limit of junior wizard apprentice. Tomorrow I should try to break through," Merlin thought to himself.
