In the next few days, Zhao Zheng would go back to the Chūn Medical Center every day to spend money to listen to Lin Jiyuan, an old money fan, give lectures, and after a few days, he had already had a first glimpse of the way of alchemy and understood a lot of basic knowledge. On the third day, he bought some cheap medicinal materials from Lin Jiyuan, and went to the grain store to buy some materials that were not available back to the Chūn Medical Center, planning to refine a few grains of Fruit Belly Pill to practice his hands first, and then to refine the precious Tiger Bone Pill when he became proficient in the future.

Zhao Zheng returned to the compound with the medicinal herbs, and found that Li Zhenzhen was missing again, in the past few days, Li Zhenzhen had been walking around by herself because she felt bored with alchemy, and only came back at night. Li Zhenzhen's ability is much higher than Zhao Zheng's, but she doesn't have to worry about her.

Zhao Zheng returned to his room, stored all the medicinal materials in the warehouse, then sat on the bed, closed his eyes and sank into the system, opened the [Dungeon] list with his mind, and spent 1,200 points to unlock the [Alchemy Room].

Unlike other quests, this quest can be entered with items, but only medicinal herbs can be brought in, and the medicinal materials must be stored in the system warehouse beforehand. Zhao Zheng clicked on the copy of the alchemy room, and after some scanning, he listed all the medicinal materials in the warehouse, he selected them one by one, and then paid for the points needed to enter the copy.

His eyes were black, and when he opened his eyes again, he had already entered the alchemy room, and he had changed into a set of clean brown sè shorts.

The time limit for the alchemy room copy is relatively long, up to a day, and it seems that it can also be used for practice, so there is no need to do alchemy. However, the points required to enter here are more than those of the Empty Meditation Room, and if it is purely for practice, it is better to go to the Empty Meditation Room. The space of this copy is not large, only about fifty square meters, boxy, except for the thatched house, there are no other extra rooms.

On the side of the alchemy room, there is a tall medicine cabinet, which stores the medicinal materials sent in by Zhao Zheng, and on the corresponding cabinet, there are labels for several medicinal materials, and in front of the cabinet, a ladder is erected. On the other walls, several small lamps that shine on the glass extend out, emitting a soft light, and the light source inside is not a flame, which is very stable, avoiding the danger of burning caused by sparks.

Of course, the most important furnishings in this room belong to the wide variety of alchemy equipment, in the main zhōngyāng of the house there is a bagua-shaped platform, on the platform is a gourd-shaped alchemy furnace, the gourd is made of brass, the bottom has four legs, carved green dragon, white tiger, vermilion bird, Xuanwu four kinds of beasts. There is an opening on the belly of the gourd, and inside is a stove, which can be used to set up a fire. There is a clear horizontal print on the gourd, which is the lid at a glance, and it can be removed.

In addition to the alchemy furnace, there are many other equipment on the side, such as pomegranate jars, crucibles, grinders, huachi, silk sieves, horsetails, etc., each with its own use.

Zhao Zhengdong took a look, looked west, fiddled with various tools, and after seeing enough, he began to officially alchemy. He climbed up the ladder and took out all the herbs that the system had helped to store in the drawer, weighed them in good portions, and placed them on the plates on the table one by one.

Zhao Zheng remembered a lot of prescriptions in his heart, but all he remembered were some precious prescriptions, such as the common pill of the stomach pill, but he didn't know what medicinal materials he needed to use to refine it, this prescription was asked by him from Lin Jiyuan in the past few days.

The reason why he only remembered the precious prescriptions was because in the process of playing the game, these medicinal materials needed to be collected in one piece, which took a lot of effort on his part, so he left a deep impression. And those ordinary pills, the materials can be bought casually, and they can be refined directly, but they didn't leave any impression on him.

Half of the ingredients are pills, and the other half is food, including sugar, peanut oil, salt, sesame and many other ingredients. With the help of these ingredients and medicinal materials such as expanding mushrooms, Lingyun grass, and coagulation grass, they can be condensed into the size of an elixir.

Zhao Zheng carried out refining according to the method taught by Lin Jiyuan, first cooking various ingredients in a pot like cooking, and then putting them into the alchemy furnace one by one in order for refining. Under the effect of solidifying the grass, these ingredients shrink sharply under the high temperature, condensing into a small ball.

Zhao Zheng kept adding materials, patiently mastered the heat, and after an hour, he finally refined the first Fruit Belly Pill.

The pill is refined, but there are many problems, this pill is the size of an orange, and the whole body is yellow, exuding a choking smell, which is obviously not delicious. Zhao Zheng took out the Fruit Belly Pill in the copy of the supplies, compared it with the Fruit Pill he refined, and found that the gap was very large, the Fruit Pill given by the supplement had a strong rice fragrance, and the smell made people eat yù greatly, and the Fruit Pill he refined would only make people hungry. In addition, the difference in volume is also very large, and the fruit belly pill refined by Zhao Zheng is more than twice as large as the normal fruit belly pill, which is simply a dough.

"Failure." Zhao Zheng sighed and threw the scrapped Hunger Pill into the trash. After he tried alchemy with his own hands, he understood the difficulty of alchemy, even refining the most ordinary belly pill was so difficult, let alone refining the tiger bone pill of the medium-grade pill. It seems that you need to practice hard for a long time before you can try to refine the Tiger Bone Pill, otherwise, you will only waste those medicinal materials in vain.

He is a person with perseverance and perseverance, and he did not retreat because alchemy was very difficult, he refined it several times in a row, kept failing, kept trying, and spent a whole day refining nine scrapped Fruit Belly Pills. When he refined the tenth Fruit Belly Pill, a copy chime sounded in the middle of the process.

[Hint: The host has reached the time limit of the alchemy room and is about to be teleported to the real world, do you want to save the copy status so that you can continue refining the unfinished pill next time?] If you choose to save, the medicinal materials sent into the alchemy room will be locked and cannot be teleported back to the system warehouse for the time being. 】

Zhao Zheng glanced at it and chose yes, planning to continue refining that Fruit Belly Pill next time he came.

Who would have thought, after clicking on a prompt, a new prompt popped up.

[Hint: The host has successfully refined the Enigmatic Elixir ×9 in the Alchemy Room dungeon, do you want to teleport it to the system warehouse?] 】

"Mystery elixir? Does this mean that the effect of the pill I refined is unknown......" Zhao Zheng smiled bitterly, it seems that the Belly Pill he refined is not only not up to standard, but may even be poisonous. He shook his head and clicked no, leaving no of these scrapped pills and letting the system destroy them.

Zhao Zheng still had a few more opportunities to enter the dungeon, but he didn't have any more alchemy materials in his hands, even if he entered the alchemy room again, it would only be a waste of time, so he didn't go again, but used the remaining opportunities to cultivate light skills.

In the afternoon, Li Zhenzhen, who was out, came back, she walked into the main room and knocked on Zhao Zheng's door directly.

"What's the reason for Lady Li?" Zhao Zheng asked with a smile.

"Isn't that obvious? It's been three days, and I'm here to ask you to take me to that so-called mysterious location. Li Zhenzhen replied.

"It's only been two and a half days now, and it's only three days until tomorrow morning."

"That's according to your algorithm, if it is according to mine, three days have passed." Li Zhenzhen obviously couldn't hold her breath anymore.

Zhao Zheng looked at Tian Sè outside the window, hesitated for a moment, nodded and compromised: "Okay, anyway, it's not bad for half a day, you come with me, and I'll take you to that mysterious location now." ”

"Really? That's great. Li Zhenzhen raised her hands and cheered, smiling her eyes into crescent moons.

Zhao Zheng left the courtyard with Li Zhenzhen and rushed directly to the direction of the south of the city. When he was halfway there, he entered a grocery store and bought a bundle of rope tens of meters long, a few candles, a fire fold and a shovel inside

In fact, it's not that Zhao Zheng is reluctant to say it, but he can't be completely sure that that place exists, after all, there are always some discrepancies between this world and the game, since he can't fully confirm it, it's better for him not to say it first, so as not to be unable to explain it because he can't find a place.

After arriving in the south of the city, Zhao Zheng inquired about some things with passers-by, asked a few local names, and asked the location of a dry well. He followed the guidance of passers-by and successfully found a dry well in the south of the city.

It's been a long time since anyone has pumped water from this dry well, but the wheels for drawing water are still there. There are some houses in this vicinity, and there is no figure in sight on the road, which is quite desolate.

Zhao Zheng put aside the rope and other sundries, lying on the dry well and looking down, the black hole below was hollow, and he couldn't see the end at a glance, and he didn't know how deep it was.

"We're here." Zhao Zheng looked at the darkness below and said without raising his head.

"Isn't this a dry well?" Li Zhenzhen wondered.

"That's right."

"What's so fun about dry wells?"

"The dry well itself is not fun, but there is no hole under the dry well."

"Treasure?"

"It's not a treasure, it's a secret passage."

"Secret passages? What secret passage? ”

"I'm not 100% sure that there is a secret passage down there, so let's go down and explore the path first, and when I find the secret passage, I'll tell you the details." Zhao Zheng looked down, his pupils constricting slightly.
