Seeing that Lu Yu was already standing in the wooden barrel, Luo Qi poured hot water into it.

Although the hot water was obviously boiling, Lu Yu didn't feel hot at all.

"Master, is this hot water 100 degrees Celsius?" Lu Yu asked.

Luo Qi nodded and replied, "Yes." ”

"But how do I feel that the water is cold, not hot at all."

"If it weren't for the hot mist, I wouldn't have noticed that it was hot water." Lu Yu asked curiously.

"Congratulations, Lu Xian, your current cultivation has improved. Indeed, the more you repair to the back, the less you can perceive cold and heat. Luo Qi said eloquently.

"That's right," Lu Yu raised his eyebrows, following the appearance of Senior Brother Qiu Lin, and said, "That's really cool, you can go in and out of the deep sea of the Sword Mountain, Fire Sea, Ice Cellar, but your body can't feel the heat and coldness of those places." Isn't that too strong? ”

Luo Qi was amused by Lu Yu all of a sudden, and he said, "Are you imitating your Senior Brother Qiu Lin's tone?" ”

Lu Yu then imitated.

"Yes or no, what's the matter? Isn't it cool to cultivate immortals? How cool is it. ”

"It's kind of funny." Luo Qi couldn't help laughing.

"That's right, Master." Lu Yu suddenly thought of something and asked.

"Master, just after collecting the herbs, I asked Senior Brother Qiu Lin, he is your first disciple who joined the Zen Yun Sect two thousand years ago. So I want to ask, he should be more than 2,000 years old, right? ”

"Yes, he has lived for more than three thousand years." Luo Qi said lightly.

"Three thousand years, so big, then he still said that he is neither big nor small." Lu Xian's eyes widened in surprise and said.

"yes, he's not that big." Luo Qi said, pointing to himself and saying, "Guess how old I am?" ”

Lu Yu searched his brain for the only knowledge he had, and finally said boldly.

"Master, I think you are as old as 10,000 years."

"That's wrong," Luo Qi shrugged his shoulders and said, "I'm more than 300 million years old." And I'm also young in the fairy world. ”

"Is that an exaggeration?" Lu Yu said, thinking in his heart, how old should the oldest immortal be!

Luo Qi seemed to have guessed Lu Xi's thoughts at once, and he said: "As for the oldest, many of them have reached hundreds of billions of years old. ”

Lu Yu opened his mouth wide in surprise and said, "Then how powerful they are, they have all lived to be hundreds of billions old." ”

Luo Qi said: "You can imagine it slowly." ”

Lu Xi soaked in the medicated bath for a while, patronizing and talking to Luo Qi, but he didn't realize that his body had been soaked smooth and delicate, and his skin was slightly transparent.

Luo Qi looked at the changes in Lu Xi's body and reminded: "Lu Xian, you look down at yourself, what does it feel different?" ”

Lu Yu hurriedly looked down, his body became transparent and clear, and his body exuded a faint fragrance of eclipse flowers, and he felt that his body had become so light when he moved slightly.

"Master, I feel that my body has become transparent and light. The smell of the flower also became weaker and lighter, apparently because I had absorbed its medicinal properties. I've been soaking for so long, when will it come out? Lu Yu asked.

Lu Yu stirred the potion in the barrel slightly, and found that the potion in the barrel was becoming darker and darker. At first, the water in the barrel was almost transparent, but now the water in the barrel is dark and dark, and the blue is getting deeper and deeper, obviously the effect of the spirit rhino grass.

"Master, why is this spirit rhinoceros grass getting darker and darker? It seems that the properties of this herb are really powerful, and it must be used for more than just medicinal baths. ”

Luo Qi heard Lu Yu ask two questions, so he answered them one by one.

"You can get out of the medicine barrel now."

"You don't have to delve into the color of this potion, the spirit rhino herb is the darker it becomes. But it also has a limit point, and when it reaches that point, the color will not continue to deepen. You see that the water is so blue and black, and the limit point is almost reached, and when you reach the limit point, the medicinal properties of the spirit rhinoceros will no longer be increased in the water. You can come out of this. The spirit rhinoceros can be swallowed directly, or it can be made into pills, and the medicinal bath is indeed more than its only use. ”

After Luo Qi finished speaking, he saw Lu Mei looking at him with admiration on his face, and a faint warmth suddenly appeared in his heart.

"Xiao Xi, there is only a limit to what a teacher can teach you. In the future, when your realm reaches a certain point, going out to experience is the best opportunity for you to learn and grow. ”

Luo Qi said, thinking of Xue Ziyan, and then thinking of Tianlian'er and Qiu Lin, these Lu Mei's senior brothers and sisters treated Lu Yu with great advice, and he was also relieved in his heart.

Lu Yu quickly got dressed and said to Shizun, "Master, what should I do next?" ”

"Pour all the water from the medicine bucket into the catalytic pool at the back of the sect. The catalytic pool is made up of a large square tripod, which is actually a magic vessel that can be turned into a treasure to refine anything in it. ”

"For example, the wastewater in your barrel this time contains two herbs, Eclipse Flower and Spirit Rhinoceros. The catalytic tank can turn the waste water in your wooden barrel into treasure, and refine all the unused medicinal properties into a medicinal pill. The water molecules that are not used up will be distilled by it to form a large vat of pure water, which is used to water the herbs in this valley. ”

"Wow, this magic weapon is amazing." Lu Yu couldn't help but sigh.

Luo Qi heard Lu Yu sigh at the power of the magic weapon, and a warmth hit his heart.

Luo Qi thought about it, whether to let Lu Yu touch the magic weapon so quickly. In the end, the answer he got was yes, because Lu Yu cultivated diligently, and it was good for him to let him get in touch with magic weapons so early.

So, Luo Qi said: "Xiao Xi, do you want to get a fairy weapon of your own to use in battle?" ”

"Of course I do, Master." Lu replied, his eyes full of anticipation.

"Very good, tomorrow I will take you to the immortal auction house and find a immortal artifact that you can see and call your hand. After all, you don't know how to refine immortal weapons by yourself yet, and being able to auction back a good immortal artifact is also a very great help to you. ”

"Lu Xi, you should rest early, you are tired of collecting herbs today, I will go back to the house to rest first. I'll wake you up early tomorrow morning and take you to the fairy auction house. ”

After speaking, Luo Qi left silently.

Only then did Lu Yu come back to his senses.

"Wow, tomorrow I'm going to have a fairy weapon of my own, I finally don't have to walk on foot, I want a fairy weapon that can fly me, how cool would that be."

Lu Xian got to work neatly. He poured all the potions from the barrel into the large tub next to him. Then he walked to the catalytic pool at the back of the Zen Sect with the wooden basin and poured all the water in the wooden basin into it.

The catalytic pool sensed the potions and spontaneously began refining them. After a while, the water in the catalytic pool began to boil and concentrate, until the pills appeared in the catalytic pool.

And that wastewater is also captured by the catalytic tank. Soon the water drifted into a large stone vat next to the catalytic tank. Lu Yu went over and looked at the water in the stone barrel, it was indeed distilled pure water.

Lu Yu hurriedly connected all the pure water to his wooden basin, and then put the four small pills in the catalytic pool into his pocket and began to go back to the dormitory.
