Lou Cen Zhi picked out some interesting things he encountered in the mortal world, but the mortal people have been ascetic cultivators for a long time, and there is really nothing worth mentioning, Lou Cen Zhi suddenly clapped his hands: "Ah, there is one thing, Senior Sister Lin will be happy when she sees it." With that, he took out the jade box from his arms and handed it to Lin Yuanchen.

Lin Yuanchen opened the jade box, only to see that there were white particles like fine sand inside, and she was stunned: "What is this?"

Lou Cen Zhi smiled: "This is sugar." ”

Lin Yuanchen said: "Senior brother, don't visit me, I remember the sugar in the mortal world, in addition to honey in the mortal world, there is only brown sugar, this thing is like snow and sand, how can it be sugar?"

Lou Cen Zhi said with a smile: "This thing is called snow sugar, it is newly made in the mortal world--" He elaborated on the snow sugar made in Houlong Village, and when he heard that the snow sugar was poured with yellow mud water and the snow sugar came out, Lin Yuanchen nodded: "I know, the reason why this brown sugar is red is that there are too many sundries in it, and it can be washed away by drenching it with yellow mud water." Well, it's really dirty to use yellow mud water, if you first dissolve the brown sugar water, and then use other things to absorb the debris, you can also make snow sugar. ”

If Guo Dalu is here, he will definitely applaud Lin Yuanchen's analysis, in fact, brown sugar to snow sugar is a process of filtration and purification, if there is activated carbon, it is more convenient to make snow sugar, but Guo Dalu only has ordinary charcoal in his hand, and he can't make activated carbon for a while.

Lou Cen said: "Ordinary people, it is not bad to be able to find out the method of drenching sugar with yellow mud water." ”

Lin Yuanchen nodded and shook his head: "Although this snow candy is good, it is just a novelty to the table of the rich and noble, and it does not help to improve people's livelihood. ”

Lou Cen's heart moved: "Senior Sister Lin, there is something you must like when you hear it, Senior Brother has a wonderful method that can greatly reduce the burden of the people in the world." He informed Lin Yuanchen of his "invention" of the drip irrigation method: "I will send it to the emperor's old officials later, and when the drip irrigation method spreads all over the world, the people will be less burdened." ”

Lin Yuanchen's eyes lit up, and he stared at Lou Cen Zhi: "Senior Brother Lou has the world in mind, Senior Sister, I am here to thank Senior Brother Lou for the people of Limin." As he spoke, he got up and blessed Lou Cen.

Lou Cen Zhi was so happy that he couldn't even close his mouth, and hurriedly returned the salute: "It's a trivial matter, and it's a matter of effort." ”

Lin Yuanchen was in great interest, and chatted with Lou Cen Zhi for a few more words, and suddenly, there was a phoenix roar in the room, and Lin Yuanchen suddenly stood up: "Oops, that red refining fruit is going to cast a spell again, Senior Brother Lou, you go, I won't send you to Senior Sister." ”

Lou Cen Zhi was stunned when he heard the three words of the Red Refining Fruit: "Red Refining Fruit, Senior Sister Lin, why are you fiddling with it? Although this Red Refining Fruit is a high-grade immortal grass, making it into a Nine Flame Pill can greatly boost your skills, but it is really troublesome to plant. This red refining fruit is heat-loving, if it is planted in the elixir garden, no matter how much spiritual energy you have in the medicine garden, it will gradually wither, only by casting spells from time to time, using spells such as the Sun Burning Technique to forcibly increase the heat around the red refining fruit, can the red refining fruit ripen and bear fruit. ”

Lin Yuanchen had already entered the house at this time, and saw pots of small seedlings with red bodies placed on the ground in the house, this small seedling was the red refining fruit, but it was still too small, far from the point of fruition, on the contrary, those small seedlings were a little wilted.

Lin Yuanchen hurriedly cast a spell, what she performed was the Sun Burning Technique, and suddenly a round of light balls like the sun floated in the room, emitting heat to the surroundings, and the temperature in the room rose again, and the Red Refining Fruit liked the heat, and soon spread the leaves again.

Lin Yuanchen persisted for a while, slowly put away the Sun Burning Technique, and the indoor light ball disappeared, but the room was still very hot, but Lou Cen Zhi knew that the heat in this room would not last long, and when the indoor heat dropped again, Lin Yuanchen still had to cast spells.

Lou Cen looked at Lin Yuanchen with a painful heart: "Senior Sister Lin, this Red Refining Fruit is extremely difficult to plant, and the difficulty is that within a year of growth, twelve hours a day, you must use spells to forcibly increase the heat around it. Unless it is a Da Luo Jin Immortal, with immeasurable mana, it can be easily done. Cultivators like us, every time we cast a spell, we will consume our power, how can we afford such a toss? Even if we finally grow the Red Refining Fruit, after taking it, we can't make up for the lost mana, and the gains really outweigh the losses. I have heard that only the sects with the innate geothermal spiritual veins are blessed with the help of geothermal heat to grow the Red Refining Fruit, and the other sects and sects have no precedent for successfully cultivating the Red Refining Fruit. ”

Lin Yuanchen smiled bitterly: "How can I not know? I once tried to plant the Red Refining Fruit by the hot spring, or add a brazier to the house, but the Red Refining Fruit could not stand the water vapor and smoke, and soon withered. It's just that my strength hasn't increased for a long time, and even, there are even signs of the five decays of heaven and man, if I don't hurry up and use the Red Refining Fruit to practice the Nine Flame Pill and greatly increase my strength, I'm worried--"

Lou Cen Zhi was taken aback. He exclaimed, "The five decays of heaven and man refer to the filthy clothes, wilted on the head, sweat under the armpits, filthy body, and unhappiness in the cultivator's seat.

Lou Cen Zhi knew that Lin Yuanchen was not allowed to plant the Red Refining Fruit, and if he didn't plant the Red Refining Fruit before exhausting his whole body strength, the consequences would be unimaginable!

Lou Cen gritted his teeth: "Senior Sister Lin, I'll help you plant the Red Refining Fruit!"

Lin Yuanchen shook his head: "I understand Senior Brother Lou's kindness, but I can't drag down Senior Brother's cultivation." Please also rest assured, junior sister, I am not a big decline, but a small decline. The five small decays of heaven and man are that the music is not sound, the body light is flickering, the bath is in the water, the environment is reluctant, and the eyes are instantaneous. If I can't grow the Red Refining Fruit, I will at most use all my mana and return to the mortal world, and I will not worry about my life. ”

Lou Cen Zhi regretted it in his heart as soon as he said it, you must know that every bit of mana of a cultivator is hard-won, and cultivation is more like sailing against the current, if you don't advance, you will retreat, and every bit of mana you consume, I don't know how long it will take to make up for it. Therefore, although Lou Cenzhi was heartbroken and Lin Yuanchen's face was haggard in order to plant the Red Refining Fruit, he did not insist on helping her cast spells.

Lou Cen Zhi said goodbye and left Lin Yuanchen's small courtyard, and returned to his house at the outer gate - the outer disciples all lived on the shore of East Lake, Lou Cen Zhi closed his eyes and pondered for a long time, opened his eyes and sighed long, he couldn't think of how to help Lin Yuanchen grow the Red Refining Fruit without consuming his own strength.

After staying for a long time, Lou Cen Zhi remembered that he hadn't sent an immortal note to the current emperor, so he immediately took out the jade talisman given by the pavilion master, and after a while, the jade talisman was windless and automatic, turning into a little streamer and disappearing into the sky. ---------------------------------------------------- thanks to the obscene laughter and the heavy snow for the reward.
