A few blazing torches were stuck in the wall, illuminating the small courtyard.

In the courtyard, Chu Fan and the Taoist priest named Lingxuzi squatted on the ground regardless of their heads, looking at a small porcelain bowl.

Liu Zhongwen and Zhao Hai on the side looked at each other and smiled bitterly, the latter shook his head, went straight out of the wooden door, and returned to the guards sitting in the woods outside the door—Yiqiguan was too small to fit so many people.

After knocking on the door just now, Liu Zhongwen and Lingxuzi exchanged greetings for a while, Liu Zhongwen expressed his intention to make a move, and Lingxuzi was also happy, so after the C-shaped team lit the torches, the two moved their hands in the open space in front of the door.

As a result, just after a few moves, the Lingxuzi jumped out of the circle and shouted a timeout—he found that Chu Fan had gone into the courtyard to check on his altars and jars.

As soon as Lingxuzi entered the courtyard and was about to stop it, he heard Chu Fan cry out in surprise, "This is sour!" ”

Lingxuzi immediately corrected him and said, "This son must not talk nonsense, this is green alum oil...... What is acid? ”

In the light of the torches, Liu Zhongwen saw Chu Fan's face full of ecstasy, his face was flushed, his hands were trembling slightly with excitement, and he asked Lingxuzi in a stacked voice, "Dao Chief, what is this...... Alum oil, but it will make paper and cloth black? But will it make the iron piece bubble? But it burns the skin? ”

Lingxuzi let out a "huh", staring at Chu Fan Dao with glowing eyes, "That's true!" …… It's just that this thing is a secret medicine of the immortal family, how does Childe know its habits? ”

Chu Fan smiled and said, "Not only do I know this, I also know that this sulfuric acid, oh no, the gas that comes out after the reaction of the alum oil with the iron flakes can ignite!" ”

"Oh?" Although Lingxuzi didn't understand what the so-called reaction was, he also understood what Chu Fan meant, and said in surprise. "The iron was thrown into alum oil, and bubbles escaped...... Is it still combustible? I don't know about this poor road. ”

The two chatted without even asking each other's names, and threw Liu Zhongwen, who had been half-struck, aside, extremely depressed.

Later, Chu Fan even asked the C-shaped team to insert all the torches on the wall, and Zhang Luo and Lingxuzi moved out the porcelain bowls and plates, and started the experiment with great interest.

Seeing the martial arts competition, it turned yellow. Liu Zhongwen simply squatted beside the two of them - although he only had three moves and two styles just now, he had already found that Lingxuzi's kung fu was very similar to his own, so he was eager to find out if Lingxuzi was also a member of the Taishan faction.

“…… Be careful, this alum oil is the most hurtful, and it is a big blister when it hits your hands. Lingxuzi saw Chu Fan throwing pieces of iron into the small porcelain bowl, and hurriedly reminded.

"I know, I know." Chu Fan then returned, looking at the porcelain bowl intently, the surface of the iron block really began to produce bubbles, but it was estimated that the concentration of this sulfuric acid was too low. Bubbles grow slowly.

Liu Zhongwen saw that the two of them were staring at the porcelain bowl and didn't speak, and felt that the opportunity had come, so he interjected, "Lingxu Dao Chief, there is something ...... down there."

"Duh, don't speak! Just watch! Before he could speak, he was interrupted by Lingxuzi, who didn't even look at him.

Liu Zhongwen was stunned - Lingxuzi's behavior is not to say that he is a first-time acquaintance, but he is as close as a family member. It's also quite rude.

However, Liu Zhongwen is a rather rough person, and he sees not only Lingxuzi. Even Chu Fan was engrossed, staring at the bubble of the iron that was gradually getting bigger, while taking out the fire fold and lighting a piece of firewood and grass, and when the bubble finally broke free of the iron and quickly rose to the surface of the water, he brought the firewood and grass to the liquid surface.

"Boom~~"

After a soft sound. The pure blue flames burst open and vanished into the night.

"Wonderful! Wonderful! Lingxuzi, who had watched the whole process with round eyes, praised, "The qi produced by this green alum oil can really burn...... And it burns so fairy, isn't it the legendary Nanming Lihuo? ”

Chu Fan laughed out loud, shook his head and said. "Is it still samadhi...... That's hydrogen! ”

"Qingqi?" Lingxuzi frowned and asked, "What kind of qi is Qingqi?" The poor road but smelling a Qi and three Qings is a Qi view of the thatched nunnery where it lives...... Childe's saying that this pure qi is related to what Lao Jun said? ”

Chu Fan was stunned for a moment, and didn't know how to describe the simplest hydrogen and hydrogen elements in chemistry to him, and thought for a long time, at the molecular level, as long as the technical means are sufficient, can hydrogen atoms be used to form any other molecules?

So he simply nodded and said, "Yes, this hydrogen gas is a Qi, which turns into three clears, and then differentiates into all things in the world." He was also overexcited because of the discovery of sulfuric acid, and actually explained the hydrogen element according to Lingxuzi's words.

"Hiss~~ What Gongzi said, this pure qi is not like a Qi, but seems to be like the one in the "Tao Te Ching", "Tao gives birth to one, one life to two, two to three, and three to all things"?" Lingxuzi pondered for a long time, and then muttered, "I wonder if this explanation of the poor road is appropriate?" ”

Chu Fan was regretting what he had just said, and he happened to get off the donkey down the slope at this moment, "What the Taoist chief said is extremely ...... Everything in this world is made of elements, and hydrogen is the simplest and easiest to figure out...... The so-called Taoist, it is most appropriate to start studying hydrogen from this...... I don't dare to ask, how did this green alum oil channel chief come about? ”

"It's easy to hear." The topic turned to the knowledge of Lingxuzi, and his face was immediately filled with an expression of pride and surprise, and he pulled Chu Fan to look through those jars and jars like offering treasures, just like a child showing off his beloved toys.

Liu Zhongwen, who was left to dry, was completely speechless, and sat silently on the stone in the courtyard, watching the old and young people discuss what alchemy things such as green alum, dansha, and realgar, and secretly kept shaking his head - originally he heard that Lingxuzi was a master, and he planned to come over to compete with him.

Hey! It's true, these two still call each other "Childe" and "Dao Chief", and no one even knows each other's surnames.

Now the two of them were talking about what green alum and saltpeter could be refined together to get green alum oil, and he was so excited to hear it that he took a nap after a while.

"Oops!"

In a daze, only to hear an exclamation, Liu Zhongwen jumped up, and subconsciously went to his waist to draw a knife, but only to see under the clear moonlight, Ling Xuzi and Chu Fan, who were squatting on the ground and tinkering with something, turned their heads to look at him, as if they were looking at some monster.

Seeing that everything was normal, Liu Zhongwen curtly withdrew the hand pressed on the handle of the knife, and said with a wry smile, "Little Fu'er, what are we here for?" ”

With his reminder, Chu Fan remembered his original intention as if he had just woken up from a dream, patted his head and arched his hand at Ling Xuzi and said, "Dao Chief, we still have one thing to inquire about, to go to this eagle's beak, in addition to the dangerous path in front of the mountain, is there any other way?" (To be continued.) )
