On that day, Zhang Xing stayed in the side hall of the Beast Hall valley. He didn't go back to the guest room in the headquarters. It was too troublesome to go back and forth.
He didn't have any idea about what kind of pill to refine. He flipped through the knowledge of pills in his mind and seriously thought about it.
"There must be a lot of people who can refine elixirs that can raise the level of magical beasts. It's not outstanding, so I won't refine it."
"Pills that can develop the wisdom of magical beasts seem to be very difficult to refine. Should I go in this direction?"
"Although I haven't refined it before and don't have a pill recipe, I can give it a try."
Thinking of this, he took out a pill furnace and then began to daydream.
… …
The next morning, at the headquarters of the Beast Hall, Kechila listened to the report of his disciple.
"Hall Master, City Lord Zhang Xing has been daydreaming in front of the pill furnace for the whole night. He didn't do anything."
"En, you can leave!"
Kechila waved his hand. He was also looking forward to Zhang Xing coming up with a novel prescription. The first to benefit was the Beast Hall. Why not!
In the eyes of outsiders, Zhang Xing had been in a daze. However, in his mind, he had done countless simulations of the medicinal properties of various medicinal herbs, as well as their mutual promotion and suppression. At the very least, he had made a breakthrough in theory.
On the third day, he began to practice.
Among the materials provided by the second-rate countries, there were countless herbs. It was enough for him to refine for a long time.
Therefore, he wasn't afraid that he would fail. With his current knowledge of refining pills, he could compete with Bulwer's level 4 doctor. It was just that he had less experience.
In fact, in his subconscious, he was still refining the bloodline pill.
But it couldn't be exactly the same. He had to research several herbs to replace one.
The difficulty had undoubtedly increased by several times, but the effect was hard to say.
After more than ten days, he had wasted countless herbs, but he didn't refine a decent pill. Most of them had turned into black ash.
Zhang Xing wasn't discouraged. He deeply understood that Rome wasn't built in a day.
He continued to experiment. 20 days, 30 days, 40 days … 60 days.
For two whole months, he didn't refine a single pill. His refining level had increased by several times.
On the sixty-first day, he unexpectedly refined a gray pill that was neither round nor round.
He recalled the process of refining the medicine. How many materials were used, the intensity of the fire during the refining process, and the beginning and end of the refining process.
After memorizing everything, Zhang Xuan continued forging.
"If I can successfully refine one pill, then I can refine a hundred pills!"
Zhang Xing deeply agreed with this saying.
In the following days, Zhang Xing's entire mind was immersed in alchemy. From beginning to end, he was pacing back and forth between Meticulous Mind, Heaven Man Unity, and the True Meaning of Realm.
Slowly, all the Beast Hall disciples who were waiting on Zhang Xing had run away. No one could stand this boring life. They would stay here for two or three days without saying a word and repeatedly concocting medicine.
Another month passed, and Zhang Xing had already refined a pile of unknown pills. There were six or seven different colors piled up together, looking like a pile of half-useless elixirs. No one would think that these elixirs would have any use.
On this day, Zhang Xing stood up and stretched his muscles.
"It has already been three months. There are still four months left. I have to hurry up with the experiment."
Zhang Xing muttered to himself.
He immediately walked out of the side hall and began to catch some low-grade magical beasts in the cages. After a round, he caught quite a number of rank one or two edible magical beasts.
After returning to the side hall, he placed the pile of pills in the room of the Dragon Island castle.
After that, he casually took out a pill, checked its composition, and threw it to a rank two magical wolf cub.
