Sun Zhengyang saw Lin Chen turn over and look over to observe, and he didn't expect him to see anything, after all, identifying pills also requires a certain foundation: "Don't look at it, top grade, identifying the quality of pills is also an ability that alchemists must master, continue to practice." ”

It can be seen that Sun Zhengyang is still not very satisfied with the quality of this pill, but Lin Chen is already envious, and he has casually practiced a top-grade pill, although it is only the lowest level of the Yellow Rank Pill, but in Lin Chen's opinion, it is already very powerful.

The pill is divided into four levels: heaven, earth, Xuan, and Huang from the level, the yellow level pill is the lowest level of the pill, and there are legendary immortals and gods above the heavenly level, but no one has ever seen such an elixir, just a theory, the immortal product can be simply understood as the elixir, and the divine product is the divine pill.

And the lowest-grade yellow-rank pills like the Qi Gathering Pill are relatively simple to refine, and the time for alchemy is also very short, like some high-grade pills that Sun Zhengyang is refining now, it basically takes a few days to refine a furnace.

Lin Chen continued to try, putting his spiritual power into the alchemy furnace as Sun Zhengyang said, carefully observing the reactions of the various stages of the material.

The third time, failed.

Lin Chen was not discouraged, the fourth time finally succeeded, and a strong medicinal fragrance spread out when the pill was baked.

Sun Zhengyang was attracted by this medicinal fragrance, stretched out his hand, beckoned the elixir that Lin Chen had practiced into his hand, and took a look.

"Good boy, the first time I have refined the top-grade elixir, I see that the quality is close to perfect."

Sun Zhengyang was also a little surprised.

"Really?"

Lin Chen was stunned for a moment, but his face was overjoyed, and he was close to the perfect quality, which means that the Qi Gathering Pill he refined was even better than Sun Zhengyang's.

"Don't be complacent, it's just that an elixir doesn't prove anything, maybe it's luck, continue."

Sun Zhengyang said mercilessly.

Lin Chen didn't feel any frustration because of Sun Zhengyang's blow, after all, this was the first time he had succeeded in alchemy, even if it was just luck, he was already very content.

Continue with alchemy.

After having a successful experience, Lin Chen then succeeded in refining a few Qi Gathering Pills, and after calculating, the success rate had reached about seventy percent since his first successful alchemy.

On the first day of alchemy, there was such a high success rate, and Rao and Sun Zhengyang couldn't help but be a little surprised.

Then Sun Zhengyang briefly appraised the quality, and was surprised to find that they were basically the top grades, and there was even a perfect quality.

"Senior, isn't my luck very good?"

Lin Chen asked weakly.

The first alchemy produced a top-grade elixir, Sun Zhengyang said that it was luck, which instilled a concept in Lin Chen, the quality of alchemy depends on luck.

"Stinky boy, once in a while can be said to be luck, and a few times in a row is not a matter of luck."

Sun Zhengyang said angrily.

This stinky boy must have no problem with his brain if he can refine so many high-grade pills, so he asked this on purpose.

However, the success rate and quality of Lin Chen's alchemy did surprise him.

"Is it a real fire problem?"

Sun Zhengyang said to himself.

Not a matter of luck? That was a technical problem, Lin Chen suddenly laughed: "I am really an alchemy genius. ”

Seeing that Lin Chen looked like he was underbeaten, Sun Zhengyang unexpectedly didn't hit him again, and said with a smile: "The old man really didn't see the wrong person, yes, continue to work hard and strive to get the first place in the Alchemist Conference." ”

"Huh?"

As soon as he said this, Lin Chen suddenly wilted again.

Looking at Sun Zhengyang's posture, it doesn't seem like he's joking, the co-author really wants to let himself go to the alchemist conference to compete for the first place, which is too much to look up to.

"Why are you stunned, keep practicing."

Under Sun Zhengyang's strict supervision, Lin Chen continued to start refining the Qi Gathering Pill.

His alchemy technique became more and more proficient, and the success rate reached eighty percent on the first day, and the time for each furnace of pills was also shortened, Sun Zhengyang was still very satisfied with such a speed of progress, and two perfect quality Qi Gathering Pills were produced on the first day.

In the same way, occasionally producing one perfect quality can be said to be luck, and refining two perfect qualities in a day cannot be said to be luck, if you have to say it, it can be said to be a chance.

When Sun Zhengyang first studied alchemy, it was good to occasionally produce a high-grade pill, this is still a recognized alchemy genius, if he is replaced by someone else, he can produce a medium-grade pill at the beginning, even if he is very talented.

Could it be that this stinky boy is really an alchemy wizard?

Sun Zhengyang boasted that he was not inferior to others in alchemy, if compared with him, an alchemy genius, Lin Chen could indeed be called an alchemy genius.

This made Sun Zhengyang even more interested in Lin Chen's true fire, in his opinion, the reason why Lin Chen's success rate is so high, and the quality is generally very high, should have a great relationship with the real fire.

Because true fire is also a key factor in improving the success rate and quality of alchemy.

In addition to some innate true fire and acquired true fire, there is also a saying that mutates true fire.

Lin Chen's true fire was cultivated by absorbing beast fire, strictly speaking, it was not an innate true fire, and it also belonged to the category of acquired true fire, and the color of the acquired true fire was roughly the same, but there was no golden true fire like Lin Chen.

There are indeed records of mutated true fire in ancient books, but there is no detailed record of the specific difference between mutated true fire and ordinary true fire.

So Sun Zhengyang only suspected that Lin Chen's true fire might be a mutated true fire, because he hadn't seen what the mutated true fire looked like.

It was precisely because of the true fire that Sun Zhengyang had the idea of teaching Lin Chen alchemy, and he didn't even assess whether Lin Chen had talent in alchemy.

To say that it was just a suspicion before, now Sun Zhengyang is very sure in his heart.

Because only this explanation is reasonable, even if there are many geniuses in alchemy in the Dan Sect, there is no such high success rate and quality as Lin Chen, who is new to alchemy, and even most of the disciples who are considered to have good talent are difficult to succeed in alchemy in one or two days when they first come into contact with alchemy, but Lin Chen only tried four times and succeeded.

Innate True Fire is rare, but people with mutated True Fire are also extremely rare, if those old guys in the Dan Sect know about it, it is possible to catch Lin Chen to do research, after all, True Fire is extremely important to alchemists.

The next day, Sun Zhengyang still asked Lin Chen to refine the Qi Gathering Pill, but let him increase the amount of materials he put in.

There are two main factors that determine how much a furnace of pills can produce, first, the amount of input materials, and second, the rate of pills.

Alchemy is not a material that can only be put in one at a time, and the amount of material to be invested is determined by the needs of alchemy and the ability of the alchemist.

Like some low-level pills, the alchemist will increase the amount of materials invested in order to save time, but it is not that the more input, the better, if the alchemist's ability is not enough to forcibly add a large amount, it may make the entire furnace of pills fail, so the specific amount of materials to invest depends on the situation.

A lowest-level Huang-rank pill like the Qi Gathering Pill can only refine one pill at most in one material, and if you want to refine two Qi Gathering Pills in one furnace, you need to invest at least two parts.
