After a while, the three old men returned.

"The first-order agent Ronglincao solution, the second-order agent Nabelium hormone, and the third-order agent Corson metal softener, ten bottles of each agent." Sander announced the game. "Now, get the materials and equipment ready, and get ready to go."

The three of them immediately called up the equipment and materials as they were told. The young man squinted at Lin Feng, and seeing that Lin Feng was only using those basic equipment, he snorted coldly in disdain. The woman also glanced at Lin Feng's equipment, and a trace of doubt flashed in her eyes, but she didn't speak.

"First of all, let's introduce the contestants of this competition!" Xander smiled.

"First of all, it's Kenna's brightest new star, Yao Bailong, who reached the top of the third-order pharmacist at the age of 18! He is the idol of all the rookie pharmacists in Kennastar, and he is definitely a strong contender for the guaranteed spot! Sander first introduced the proud young man. The young man raised his head proudly, and his gaze at Lin Feng became even more disdainful.

"By the way, Lin Feng, you don't know yet, right? Kenna has two guaranteed places, and he doesn't need to participate in the Planet Tryouts, he can directly participate in the Galaxy Competition, but now—" Sander gestured to the young man and the woman. "There are three contenders, so we're going to knock out one. They want to eliminate you and show them what you're capable of! ”

I see, is it because I want to squeeze out a place for them, so I am so hostile to myself? Lin Feng suddenly realized.

"Old immortal, don't talk nonsense, hurry up and play!" The old man with the red nose shouted impatiently.

"Okay, then let's move on." Sander pointed at the woman again. "Stan Qianling, the flower of the potion of the Stan family, the largest apothecary family on Kenna, reached the top of the third-order pharmacist at the age of 17, and his strength is amazing. At the same time, he is very beautiful, and he is the dream lover of countless sons. Lin Feng, you can catch up! ”

Lin Feng was stunned for a moment, and couldn't help but look at the woman. The woman looked back and smiled, as if a hundred flowers were blooming. Lin Feng was not afraid, and responded with a smile, but secretly scolded Sand for being indecent in his heart.

"Without further ado, the game begins!"

Modulation begins.

None of the three potions selected for this contest are general-purpose potions, and even in the recipes provided by Shiraku, there is no way to blend this elixir. It's not that the formulations of these agents are rare, but that the application surface is too narrow. Most of the formulas of this elixir will not have much impact on strength, so they can basically be found on the Internet. Therefore, the three old men did not make it difficult for them and provided them with a formula, but the formula was only a rough one, and there was no specific preparation method......

The pharmacist Rong Lincao solution to be prepared in the first round of the competition is a mecha coating elixir, green, which can be attached to many kinds of metals, and has strong dependence, even some third-generation aircraft can be used.

Lin Feng began to look at the formula. The core of the configuration of Ronglin grass solution lies in the purification of Ronglin grass juice, and the more transparent the purification, the better. After purification, two stabilizers are added to the grass juice, which is a bottle of Ronglin grass solution. However, the more transparent the purification, the smaller the proportion of stabilizers required, and theoretically if purified to full transparency, stabilizers are not needed at all.

Looking up, Yao Bailong had already begun to purify the first bottle of potion. The purification method he used was a typical centrifugation method, where the grass juice rotated at extremely high speeds to stratify each ingredient, a technique that was difficult for even some fourth-order pharmacists to master. This is a good choice, but Lin Feng feels that it seems a little too simple.

Look at Qianling again, the filter method is used, and the separator net of different densities is filtered in turn, although it is difficult to purify to the limit, but it is not difficult to win, and it is very safe. But looking at the separator net used by Qianling, it seems to be very special, the filtration effect is very outstanding, and the grass juice has begun to be a little transparent.

So, which filtration method do I use?

Lin Feng began to recall the medicinal properties of this material, and remembered a sentence in the introduction of this material of the material Rong Lin Grass of the Material Encyclopedia Squadron: Rong Lin Grass is the favorite food of wild creatures called green cows, and their gastric juice can separate all the impurities of the entire Rong Lin Grass for easy absorption.

Yes, this is it! Green cow's gastric juice! Just use the drug purification method!

Lin Feng hurriedly took out a group of green cow gastric juice and put it in a beaker, and then poured a bottle of white turbid liquid in his hand. This is a protein activator that works to keep the body fluid of living organisms alive. Seven seconds later, the transparent green cow gastric juice became milky white, and it began to squirm as if it had come to life, Lin Feng knew that it was time, thought about it a little, and poured in a piece of Ronglin grass juice first.

The green Ronglin grass juice spread out in the green cow's stomach juice at once, and then changed rapidly, and the grass juice was quickly divided into two parts, one part was yellow with powdery precipitated liquid, and the other part was completely translucent Ronglin grass solution. The milky white green cow gastric juice is suspended between the two liquids, and the beaker turns into three colors, which is very beautiful.

"It worked!" Lin Feng's eyes lit up, and he used a catheter to channel all nine parts of Ronglin grass juice into the green cow stomach juice in the middle, and then began to use a pipette to move the isolated Ronglin grass solution to the sealed medicine bottle.

"Huh?" The three old men were very surprised when they saw Lin Feng's movements.

"Ronglin grass juice can be separated with green cow gastric juice?" The thin old man was shocked.

"I know that the green cow likes to eat Ronglin grass, but the green cow's gastric juice can separate the function of Ronglin grass juice...... I really don't know. The red-nosed old man shook his head, also with a face full of incredulity.

"Haha, I'll just say it! This kid is a genius! After being surprised, Sander was very proud.

The configuration continues.

The first to complete the configuration was Qianling, ten bottles of Ronglin grass solution were lined up, almost transparent, and you had to look carefully to see that little bit of green.

"Ninety-eight percent purification, very powerful!"

"Qianling, this little girl is good."

"This thousand-yarn filtration method has won the true inheritance of his father!"

The three old men were full of praise for Qianling.

Qianling's personality is very calm, and in the face of the praise of the three seniors, he only bowed his head slightly, and he was thoughtful. After saluting, Qian Ling looked at Yao Bailong first. Yao Bailong was still concentrating on extracting the solution little by little with a pipette on the centrifuge, looking very careful.

The centrifugal method tends to be perfect, and it is worthy of the white dragon! She secretly praised in her heart, and then moved her gaze to Lin Feng.

Because Lin Feng started relatively late, he is still filling the eighth bottle. Qian Ling could see at a glance that Lin Feng was using the most basic drug purification method, and a trace of disdain flashed in his heart. In fact, the first thing she thought of at the beginning of the competition was the drug purification method, but after calculation, it was purified to 80% at most. The opponents are all elites, and this kind of result is definitely not good.

Looks like Old Man Sander has lost his eyes. Qianling said secretly in his heart.

Just a few seconds later, Yao Bailong was the second to complete the configuration. Ten bottles of Ronglin grass solution were neatly stacked in two rows, and the transparency was not much better than that of Qianling's works.

"Ninety-seven percent purity, but it's a pity that it's a little bit worse."

"He is worthy of being the most talented young talent in Kennastar."

"Centrifugation has become a master."

Yao Bailong was immersed in the boasting of the three seniors, and he was triumphant. It's a pity that it's a little worse than Qianling, but it's nothing, Qianling is from a big family, and the starting point is very high, and this gap will soon catch up. And Lin Feng ......

Yao Bailong glanced at Lin Feng, who was about to complete the configuration.

"Drug purification method, naïve!" He pouted in disdain. Just because of this kind of person, he even wants to compete with himself for the escort place? What does Old Man Sander think?

After a few breaths, Lin Feng also completed the configuration.
