The sky gradually became brighter and newer.

Luo Qi came to the courtyard of Lu Yu's dormitory, gently pushed the door and walked in.

As soon as Luo Qi walked to the study in the courtyard, he saw that Lu Yu was already reading the book of medicinal herbs at the desk.

Lu Yu looked down at the book and was fascinated, not realizing that Shizun had walked in. In addition, Luo Qi walked without a sound, and Lu Xi's skills were still shallow, so he couldn't detect Luo Qi's existence.

Luo Qi expressed satisfaction with Lu Mei's serious learning attitude, and did not immediately call Lu Mei, but walked behind Lu Mei.

Watching Lu Yu take out the highlighter he brought from the mortal realm and mark the key words and sentences on the paper in the book, Luo Qi suddenly felt that Lu Yu was really young, and he was simply a seedling in the fairy world.

Luo Qi walked around, suddenly opened the closet, and looked through Lu Xi's clothes to see if he needed to buy him a few clothes for practice.

Suddenly, Luo Qi found a new alchemy furnace in the closet, a round and small brown-red alchemy furnace. If you take a closer look, the inner tank of the alchemy furnace is actually gold-plated, which looks quite expensive.

Luo Qi thought to himself, he hadn't given Lu Yu any alchemy weapons, this must have been a gift from someone else to Lu Yu.

Luo Qi thought that this was either Tianlian'er or Qiu Lin's gift to Lu Xi.

This gift is quite intimate, Lu Yu just learned how to refine medicinal herbs, and this kind person gave Lu Yu a Ding alchemy furnace. When he looks back and knows who sent it, he must thank him well.

Lu Yu raised his head at this time and rested with his chin for a while, he suddenly saw a long black shadow cast in front of him, and when he looked back, there was indeed someone, it turned out to be his master Luo Qi here.

Luo Qi smiled and said, "You finally found out that I was here." ”

Lu Yu immediately stood up to greet Shizun and said, "Master, you just happened to come, I have a lot of things I don't understand in this new book, and I want to ask you." ”

"Oh, what's your problem? Tell me slowly. Luo Qi said, he sat beside Lu Yu and looked at the book of herbs on the desk. I saw that the books were densely filled with small black letters.

Luo Qi asked by the way: "Lu Xi, now that the weather is getting colder, do you need me to buy you a few thicker clothes for practice?" ”

Lu Yu listened and said, "Thank you for your concern, I do feel that the air here has become colder, and I can buy a few new thick clothes." ”

"Very well, I see, let's move on to the questions in this book."

Looking at Luo Qi's concerned eyes towards him, Lu Yu's heart warmed, and he immediately turned the pages of the book, turned to a few doubtful places and asked one by one.

"I don't understand this place, Master. According to the book, the flowers of this Danhe grass are highly poisonous enough to kill people, but why does the book immediately say that the stems and leaves of this Danhe grass can be used to relieve this poison? Lu Yu asked, he looked at Luo Qi expectantly, hoping that Luo Qi could bring him some new enlightenment.

Luo Qi immediately said: "This is a reflection of the fact that things in this world are mutually reinforcing. You see, the flowers of this crane grass are highly poisonous, and its leaves can detoxify it. In this way, when refining the detoxification pill, you must be careful to use the Danhe grass, and do not rub its petals into the herb and cause a backlash. ”

Lu Yu suddenly had a bold idea, and he asked carefully, "Master, what is the use of this Danhe grass flower?" ”

Luo Qi was not surprised by Lu Xi's question, he said leisurely: "Although the flowers of Danhe grass are highly poisonous, after advanced refining methods, they can turn the toxicity into medicinal properties, which can be used to heal injuries, and can also play a role in anesthetizing and healing wounds. ”

Lu met did not get the answer he expected, and was a little discouraged. Luo Qi saw the change in Lu Xi's expression, and he continued: "If you want to use the toxicity of the Danhe grass flowers to refine the elixir, then let me tell you, this will never work, because the flowers of the Danhe grass are very toxic, if you don't know the situation, you make it into a poison pill and use it to poison others, then it is very likely to kill others with one move." ”

Lu Yu asked, "Then there is no place to use the poison of Danhe grass flowers?" ”

"Yes, although the flowers of the Danhe grass can theoretically paralyze the functions in the human body or the immortal body to the point that they cannot move, which is extremely harmful to the human body, it also has a certain paralyzing and poisonous effect on the immortal body, temporarily poisoning the immortals at the level of the first immortal. But this kind of poison is very friendly to spirit beasts that are already poisonous insects. Poisonous insect spirit animals love to eat the poisonous flowers of Danhe grass very much, and they can enhance the viscosity and strength of their venom when they eat it, which is simply a good feed for them. ”

"But, Lu Mi, I know what you're expecting, you're wondering if you can use the poison of the Danhe grass flowers to poison your enemies in the future. Well, I'm sorry to tell you, it didn't work. Because your future opponent cannot be a mortal, but can only be a person with cultivation. And this bit of poison is not enough to be used to poison or deal with enemies. Even if the flowers of Danhe grass are made into elixirs or sprays, the effect is minimal. ”

"I know, Master, what Master has taught me is, I understand. First of all, we can't leave anything to chance, we can simply use herbs to help us defeat the enemy, and we can't be too cruel to the enemy. Lu Yu responded confidently.

"Very good, Lu Xian, you can quickly tell your next question." Luo Qi said, looking at Lu Xian's notes.

"Eh, you have a very good question here." Luo Qi said.

Lu Yu said: "Ah, that's the problem. I want to ask you, the spirit rhinoceros grass you told me earlier can be used to soak in a medicinal bath to make the body discharge of turbid qi more transparent, and I have raised a question here to see if I can use my alchemy furnace to refine the pill so that I can eat it from time to time. ”

"Because I saw that the catalytic pool had mixed the spirit rhinoceros grass with the eclipse flower and turned it into an elixir. I just thought about what would happen if the spirit rhino grass turned into an elixir alone? Lu Mian said, took out a pale green pill from his Tianzhi box, put it on the table, and pointed.

"This pill is the pill I refined with the power of the catalytic pool last time in the catalytic pool, and there are two ingredients in it, the spirit rhino grass and the eclipse flower."

Luo Qi nodded and said, "Indeed, the Spirit Rhino Grass can be refined into an elixir alone, and it can be taken at any time to refine the purity of the body. ”

"That's right, Lu Xi. Where did you put the blue sword I bought for you at Treasure Shop last time? Take it out and give it to the teacher, I want the sword to recognize the Lord immediately, so that you can use it. ”

"Okay, Master. I can't wait. I want to fly with this sword. Lu Yu said, stood up and ran to the closet, and took out a large blue flying sword wrapped in black velvet cloth from a drawer.

"By the way, you haven't named your sword yet, Lu Xi." Luo Qi reminded.

Lu Yu thought for a while, and while handing the sword to Luo Qi, he said, "Let's call it the Lan Trace Sword." ”

"Master, I almost forgot to tell you that Senior Brother Qiu Lin gave me a very useful portable alchemy furnace, and I named it the Golden Crystal Furnace. I'll show you. Lu Yu said happily.

"When you were reading the book just now, I had already discovered your alchemy furnace. Such a good high-grade portable alchemy furnace, your senior brother Qiu Lin is really willing, he is really good to you. I'm going to thank him in person. Luo Qi said, wiping the big dark blue sword clean.
