Cheng Yi threw his pig brother into the bag and carried it back to his room while An Yan stayed in the pharmacy room to make the transformation potion.

In addition to the potion to transform back into human form, An Yan also prepared a few more transformation potions for Cheng Yang, just in case he needed them.

In Cheng Yi's room, Cheng Yang was being tormented by his big brother, and his small eyes were almost filled with tears.

If it wasn't for the fear that his big brother would bully him even more, the little pink pig would have jumped on him and bit him twice!

Even though he looked small and harmless, he knew that his physical strength and explosive power were far more powerful than his human form!

But Cheng Yang's nature was simple. It was even simpler now that he had transformed into his animal form, and he didn't think of defending himself.

When he finally understood the essentials of cultivation, he immediately put all the grievances he had suffered behind him. His beady eyes were glowing with energy, and his tail was wagging and swinging in happiness. 

Having had enough of his silly brother, Cheng Yi patted his pink buttocks and said, "Now you know how good Yan Yan is to you, right?"

Cheng Yang immediately nodded repeatedly.  Of course he knew. He would have jumped right over and kissed An Yan if he was in the room.

When he first learned of the transformation potion, he was shocked and surprised, but he only associated it with a change in form.

It was only when he came into contact with cultivation and felt the dramatic increase in his physical capabilities that he became acutely aware of the immense significance of the transformation potion. 

How could Yan Yan be so powerful, so smart, and so unbelievable?

If it were him, he would not have been able to do this research even if the method of making the Transformation Potion was put right in front of him!

The more Cheng Yang thought about it, the more he admired An Yan, and the more excited and happier he was, the more his tail wagged: "Hmph, hmph, hmph!" I've never seen anyone as good as Yan Yan!

Cheng Yi couldn't understand his little brother's snorting, but he could see his emotions. He gave him another pat on the buttocks and said, "Yan Yan told you about this as a sign of trust and to help you too. So you should keep your mouth shut."

Although Cheng Yang was a cheerful person and not so defensive of outsiders, he was not really stupid. Especially when he knew the importance and seriousness of the matter. He would, of course, be extremely careful and keep it a secret.

After emphasising the issue, Cheng Yi also asked, "Are you sure you've mastered the cultivation technique?"

Cheng Yang continued to nod furiously. Of course, he would not forget such an important method.

"Let's go then. Yan Yan should have already made the potion for you to change back to human form." Cheng Yi opened the mouth of the bag and waited for Cheng Yang to get into it himself.

It did not feel good shifting around in the bag and trying to play dead without making any noise, but Cheng Yang resolutely got in. He was in a hurry to get back to An Yan.

There was already a row of potions when the two of them returned to the pharmacy room. An Yan took one bottle and handed it to Cheng Yi, saying, "Let Yang Yang drink the potion first."

No matter how well the cultivation course was, it was better to return to human form to facilitate communication.

Cheng Yi took the potion, "First turn around Yan Yan."

Although he knew that there was only a pure friendship between his silly brother and his little one, it didn't stop Cheng Yi from being jealous.  He was always very jealous, and the scope of his jealousy was ridiculously wide.

Cheng Yang gave a snort out of his nose, displeased with his big brother's jealousy. An Yan just laughed and turned away.

An Yan had not turned around even after Cheng Yang had gulped down the potion and his clothes were rustling. Cheng Yang suddenly jumped up to him and hugged him from behind, "How can you be so powerful, Yan Yan? I admire you so much! How the hell did you... "

Halfway through, Cheng Yi mercilessly pulled Cheng Yang aside by the collar: "Watch your attitude."

Cheng Yang glared at his big brother, but he didn't have time to make any more comments. He excitedly went back to An Yan's side, "Yan Yan, you're really amazing!"

An Yan was a little embarrassed with Cheng Yang's praise, so he changed the subject. "I have already made ten transformation potions for you. The ones with red labels on the bottles are to transform from human to animal form, and the ones with white labels are to do the reverse. Don’t take them wrongly. "

Cheng Yang nodded his head repeatedly, his eyes shining, "I will remember. Thank you, Yan Yan! You're really good to me. You're the man..."

He wanted to jump on An Yan again, but Cheng Yi directly stood between him and his little one, "Watch your attitude."

Cheng Yang glared at his big brother in anger, "Big brother, you can't stop Yan Yan from making friends just because you're his lover! Your behavior is very wrong! "

An Yan knew that the two brothers were just playing around, but he still smiled and waved his hand, "Let's not talk about that. Did Yang Yang encounter any problems when he was cultivating? "

Cheng Yang was particularly excited and said, "No, everything went well.

Cheng Yang was excited because he had clearly experienced the benefits of cultivation.

Apart from the changes in his spiritual domain and body, Cheng Yang's entire body felt refreshed, and his mental state had improved to the point of no return.

As soon as the words left his mouth, Cheng Yi exposed him, "Who was acting like a pig and couldn't grasp the point no matter how much he was nudged?"

Cheng Yi deliberately paused at this point and teased his brother, "Oh, I forgot, you were indeed a pig, or rather, a little pink pig."

Cheng Yang was so angry that his face turned red, and An Yan couldn't help but glare at Cheng Yi. How could there be such a big brother who liked to bully his brother whenever he had nothing better to do?

Cheng Yi rubbed his nose and added, "But at least the result is good. Yang Yang has indeed mastered the cultivation technique."

"Hmph!" Cheng Yang turned his face. Bullying is bullying, but it was Cheng Yi who corrected his mistakes and reassured him by teaching him over and over again, allowing him to grasp the cultivation methods and techniques smoothly.

"Now that you have learnt how to cultivate, then the next step is to teach you how to make the transformation potion," An Yan said as he pulled Cheng Yang's wrist back to the potion table, "I have already prepared the ingredients for you. Let's start. "

If Cheng Yang had been busy with something else, An Yan would have let him rest for a while before starting his potion making lessons.

However, although experimenting is indeed a very serious matter, the process is east. On the contrary, it was a good way to improve one's state of being, even better than resting without doing anything.

Cheng Yang was now in a very good state, and he nodded, "Okay!"

An Yan had already described and demonstrated the process in detail, but he didn’t let Cheng Yang do it directly. He gave him a second demonstration to make sure that every detail was clear before he said, "Yang Yang, you try it out."

Cheng Yang took a deep breath and began his first test.

Although he was a pharmacy student and loved making potions, he had to admit that he was really mediocre at it.  As it was the first time making this new type of potion, the result was predictable.

"Your elder brother also failed the first. He did it many more times before he succeeded. So take your time, "An Yan hurriedly comforted Cheng Yang."

Cheng Yang nodded and started the second attempt, then the third, the fourth... and by the tenth time, he was almost worn out despite being in good shape.

An Yan vaguely noticed something, but he couldn't make sense of it. So he said, "There's no hurry; let's take a break."

Cheng Yang had followed An Yan's steps to the letter in all ten attempts. An Yan had also watched from the sidelines without seeing any problems, and yet all the potions were a failure. 

The most important thing is that An Yan felt nothing even after drinking the potions Cheng Yang had made, which was very strange.

If the first time was because Cheng Yang had never worked with transformation potions before, one can say that it was because he didn’t get the hang of it. But what about the fifth time? Or the tenth?

An Yan had already described all the problems he might encounter in the process, and Cheng Yang had not encountered any problems after trying to make a transformation had they started to use it.

It was because of this that An Yan vaguely sensed that something was not quite right, but he could not grasp what it was. He could only shelf the feeling for the time being.

After resting for a while, Cheng Yang tried more than ten more times, but the result was still the same each time. The process of making the potions was fine, the potions seemed to be fine, but there was no reaction after drinking them.
