A gust of overcast wind brought a few strange noises that went far and near, and the two students who requested to change their items only felt a sudden change in front of them.

　　 The originally damaged stirring rod and some broken blades disappeared in front of their eyes as if they had been eaten.

　　 It was as if the restore button had been pressed again, and the fresh and tender leaves and the complete stirring rod appeared out of thin air in their original positions.

　　 is like magic, full of mystery, but it would be better to have less wind and weird laughter.

　　 And all this is for Geng Gui to better play, to reflect the atmosphere that should be there, he did not show his body at all, and only silently reversed the four objects through magic skills to complete the performance.

　　 "Does anyone know how these two things disappear and appear?"

　　 Yin Gu is not in a hurry to teach about herbal extraction. Anyway, there is more than enough time. Instead of letting them study unconsciously, it is better to explain everything and concentrate on the next link.

　　 "Is it a surprise attack?"

　　 "Juggling space?"

　　 "The idea is moving!"

　　 "Wonderful space!"

　　 "Snatch?"

　　 "It's all right, is there any more?"

　　 "Is it a trick?"

　　 The boy with blond hair replied uncertainly.

　　 "Very good, you got it right. The core of the skill of tricks is to exchange items between yourself and others by surprise to achieve the purpose of interference. This classmate would like you to stand up and let me know what is your name?"

　　 "My name is Song Feng Ya, but everyone likes to call me Komatsu, I am from Yuanzhu City."

　　 "Yuanzhu City is a good place. The charred tower and red maple forest are the paradise of ghost-type Pokémon. In this way, you should also have ghost-type Pokémon. Can you show it?"

　　 "Yes, come out, Ghost Stone, Dream Demon."

　　 "Jie ~ hiss!"

　　 "嘤~"

　　 Separating his hands, Ghost Stone, with his big tongue out, appeared and wandered around Komatsu, shaking his hands all around.

　　Meng Yao was quite quietly floating beside Komatsu, watching the surroundings curiously, trying to find the source of fear for food.

　　 However, these two ghost type Pokémon did not find the existence of Geng ghost, which is very intriguing.

　　 "Geng Gui, take them to play and come back before get out of class. Komatsu, do you agree?"

　　 "I can't ask for it, thank you teacher for your cultivation."

　　 Komatsu heard a surprise, and immediately responded.

　　 Under the gaze of two unknown Pokémon, Komatsu who wanted to explain it was interrupted by a strange sound.

　　 "Jiehehe~"

　　 As the strange sound emerged, two huge ghost claws appeared like catching mosquitoes, and instantly appeared to penetrate everyone, grabbing the ghost stones and dream monsters that were out of reach, and disappeared in front of everyone.

　　The overwhelming momentum of ghost claws suppressed the students within the attack range, and the fear of death and the joy of the rest of the life were intertwined to stimulate the hearts of all students.

Musashi was also shocked at this moment, but the source of her shock is more reflected in the fact that the master still has such a powerful Geng ghost. Is it because the injured Pokémon has recovered, or there are still a few of them. Severely recovered under the treatment of his mother?

　　 It seems that after class is over, I will go to ask the master carefully, and even her lovely apprentice has to hide it, and it is only now that she has made a huge shock to tease them.

　　 "Papa~"

　　 "Okay, let's continue with our previous topic. If I find that someone has deserted, a day trip to the spiritual world is waiting for you."

　　 Looking at the good children who were sitting right away, Yin Gu smiled at the goal, and began to explain formally.

　　"Nanomei has explained very clearly about the Genki Grass before, I will not repeat them one by one here. Now I take out two things, and you can help me identify what they are."

　　 After Yin Gu took out the dried yellow-white rhizomes with knots from the medicine cabinet beside him, thick rhizomes with cilia and thick fleshy brown skin.

　　If you only rely on appearance, ordinary people will not confuse these two things without knowing it.

　　 "What is this?" Yin Gu showed the rhizome with knots.

　　 "The root of vitality."

　　 "What about this one?" Yin Gu held up another rhizome.

　　 "The same is the root of vitality."

　　 "Very good, can anyone tell me why these two are different?"

　　 Most of the people looked at each other, including Jigme, Yang Nai was away because of something, otherwise she must know.

　　 Nana has been in the limelight before, and I don't want to do it again, unless there is really no answer.

　　 Musashi raised his hand.

　　 "Musashi, come and talk about it." Gingu saw Musashi raise his hand, knowing she was helping him out, scanned around and no one wanted to answer, so he called Musashi to speak.

　　 Musashi got up and talked.

　　 "Very good, the answer is very comprehensive, you sit down, now we start the formal class. First cut the Yuanqi grass into small pieces and put it in the grinding bowl."

　　 "After grinding carefully and repeatedly, you must be patient in this step."

　　 "咚咚, 咚咚"

　　 "This classmate, you are not grinding but pounding medicine. Holding the pestle and drawing circles along the wall of the mortar, that's right, you are doing well."

After 　　" is fully ground, it will quickly oxidize and become purple-red. Add pure water and pour the mixture into a beaker. Remember to keep a small amount several times until the water level reaches 400ml.

　　"After that, stir with a stir bar to mix the solution evenly and let it stand for a while."

　　 "While standing still, let's deal with peaches."

　　 "Don't smell this classmate, I know this peach fruit is very fragrant, I'm really afraid you can't help but eat the ingredients in one bite~lightnovelpub.net~No."

　　 It's okay not to answer, everyone laughed when they answered.

　　 "Okay, okay, like me, take a knife along the line in the middle, and then twist your hands gently, and the core can be easily taken out."

　　 "Peel off the skin, put the pulp in a gauze cloth, and squeeze the juice into another beaker like twisting candy."

　　 "After this step is completed, about 50~80ml of solution can be obtained. If some students don't dislike the remaining pomace, you can eat it directly, it doesn't matter, students who don't need it can throw it directly into the trash can, remember to separate dry and wet."

"The Yuanqicao solution has been standing for a while, and we can see that there is obvious stratification in the solution. We only take the upper light pink clear liquid and **** it through the glue-head dropper. Remember not to be greedy, otherwise mixed solutions will be needed. Resting again is a waste of time and inefficiency."

　　 "Why is the teacher's stratification so obvious, but mine is almost none?"

"I think the careful students have discovered this problem. You can compare the dregs at the bottom of your beakers. Is the **** layered obviously? Is the dregs of your classmates very finely divided, and the students with unobvious layering, they still Some traces of intact leaves can be seen."

　　 "Then what should we do."

　　 "Keep waiting until there is a clear stratification."

　　 "Is there a faster way?"

　　 "Yes, it can be done in half a minute by using a centrifuge."

　　 Yin Gu said a little bit evilly.

　　 "That..."

　　 Not waiting for this classmate to finish, Yin Gu continued: "But the approval will take a long time."

　　 "I will continue to wait."

　　 Seeing this small group of lost students, Yin Gu's mouth curled up.
