After cleaning up the mess in the house, she went directly to the library pavilion, and Lu Yan in the library pavilion sat upright on the library as usual, and when she saw Ling Motang coming, she raised her head slightly, so she didn't care about what she was doing. Pen & Fun & Pavilion www.biquge.info

In fact, Ling Motang's time is very free now, because of the relationship between Tsinghua University, Lu Yan is no longer mean to her, sometimes she arrives late or leaves early, and Lu Yan also turns a blind eye.

After Ling Motang said hello to Lu Yan, he went to the depths of the library pavilion, and this time he just saw Elder Qinghua, the old man was smiling brightly, which made her feel furious in her heart.

"Hello Elder." Ling Motang stubbornly ran to greet Tsinghua, and Elder Tsinghua stroked his beard: "What books have you read recently?" "It's quite a bit of a sense of déjà vu that a master examines an apprentice.

Ling Motang laughed dryly: "I haven't read any books, I've been interested in alchemy recently, so I took a lot of these books to read." ”

"Alchemy?" Elder Qinghua glanced at Ling Motang deeply: "It's a way out for you. "It's a well-known thing that Ling Motang can't use his sense of qi until now, and it's not impossible to give up spiritual cultivation and become an alchemist.

However, what Qinghua didn't know was that since last night, Ling Motang had broken through and successfully entered the ninth layer of Qi training, generally speaking, cultivators who had not yet reached the Great Perfection Stage would release their spiritual energy, so those who cultivated to a higher level could clearly know the grade of those who were lower than their own cultivation.

However, the Ling family's ancestral secret book "Empty Secret Technique" has the effect of concealing the spirit, which means that even if Ling Motang has practiced Qi Sense, others still can't tell whether she has spiritual power or not, and what level of cultivation she has reached.

Ling Motang plans to let others know that she has cultivated her aura after a while, and appropriately release a little aura, so that others will think that her grade is the third level of qi training, otherwise it will be easy to arouse suspicion if she has made too much progress.

"I heard that you went to the Strange House a few days ago to buy a lot of medicinal herbs." Elder Qinghua didn't look curious at all, but the implication was that he wanted Ling Motang to take the initiative to say the effect of buying these medicinal materials.

Ling Motang was not stupid and immediately poured beans to Elder Qinghua to report his results: "Since the spirit refining road is too bumpy and difficult to get through, then I should change my way out as soon as possible, refine a pill and make a small invention, so that I can have the face to stay in Liuyun Sect." She said the grievance, but Elder Qinghua smiled more and more happily: this girl is still flamboyant and slippery.

"Well, since you know the path you want to take, I won't ask around." Elder Qinghua knew that Ling Motang had a good memory, and he felt that it was a pity that such a person with excellent innate conditions could not transport his spiritual power and could not embark on the path of cultivation.

"These are some simple sword moves and punches, you take them back and study them yourself." Elder Qinghua had a few more booklets out of thin air: "Refining the spirit is not in a hurry, if the spirit is not successful, maybe you can take the road of martial cultivation, and you don't need to cultivate the spirit when you practice foreign kung fu to a certain point." ”

Martial cultivation is divided into nine sections, which is different from spiritual cultivation, but martial cultivation can gather and release the true qi in the body, and can confront people who cultivate spirits in terms of strength.

However, martial arts cultivation is much more difficult than spiritual cultivation, it requires great exercise of one's physical fitness, and it has high requirements for the strength and toughness of the body, unlike spiritual cultivators, who only need to mobilize the spiritual energy in the body to meditate and practice according to specific exercises, so martial cultivation is far more difficult than spiritual cultivation.

But anyone who can practice qi will not choose the path of martial arts, because the results of martial arts are slow and hard.

"Thank you, Elder." Ling Motang took the book, it's okay to do this, cultivating the spirit and cultivating martial arts at the same time, if you meet a cultivator who is evenly matched, you can also consume physical strength with the other party if you run out of spiritual energy, and you can also drag down the other party, and the actual combat of martial arts cultivation is also very high.

"Mu Xiu will be destroyed by the forest wind." Elder Qinghua was meaningful, Ling Motang chuckled, and the other party added: "But if you are too weak enough, you will also die early." ”

Ling Motang understood the meaning of Elder Qinghua's words, and the other party was telling her again, don't be in the limelight, but maybe show your strength at the right time. It is not advisable to be too weak or too conspicuous.

"Elder, all the beautiful words were said by you." Ling Motang was very depressed: "Since you let me not be too conspicuous, why do you have to take such care of me with Hua Gu in front of the disciples of the Liuyun Sect, isn't this just forcing me to be eye-catching among people?" ”

Elder Qinghua secretly scolded Ling Motang: I don't know what to do. "Hmph, you have the face to say it, but you even beat it up." Ling Motang's strength that day was too weak, if he didn't support him, would she Ling Motang still be able to take it down in the Liuyun Sect?

Ling Motang laughed twice, the old guy is not easy to fool, he originally wanted to sell miserably, but he was directly exposed.

"Okay, I'm not going to talk to you, if there is nothing else in this library, you can do your own thing, don't be able to practice foreign kung fu at that time, and come to resent me, an old thing, for harshly harsh your cultivation time." Elder Qinghua flicked his sleeves and left, Ling Motang smiled happily and thanked Elder Qinghua: "Elder, if I can enter the inner door, will I give you a long face to prove that you are not wrong?" ”

Elder Qinghua turned his back to Ling Motang, his footsteps paused, and he sighed for a long time: "Is it for yourself, what does it have to do with others?" ”

Ling Motang looked at the back of Tsinghua's departure: Yes, for yourself, if you can live according to your own ideas, it is naturally comfortable, but this comfort is difficult to come by after all.

After breathing a sigh of relief, Ling Motang continued to immerse himself in reading, and waited until sunset before leaving the library pavilion and returning to his yard to make the first step of sulfur soap.

The first step is to make caustic soda, caustic soda is also known as sodium hydroxide, the chemical formula NaOH, she found out the formation formula for making caustic soda from the manuscript paper of the previous calculation, and the raw material needed is hydrated lime, which she had already bought from the mountain for the people of Takqi Cargo House to help her buy it back from the mountain, which came in handy.

After preparing a series of raw materials, Ling Motang began to blend according to the proportion of acid, using the aura in his body to release the fire attribute, it is still good to have spiritual power, it can be used at any time when the fire is wanted, and the temperature can be controlled.

In the process of chemical reaction, it is necessary to constantly adjust the temperature of the surface of the porcelain bottle to achieve the best chemical reaction in the substance, but the porcelain bottle is opaque, and it is not clear to see when the reaction of the substance inside occurs, and it is more difficult to grasp the temperature and time of the fire.
