Yun Lan originally felt that she had nothing to prepare, but now that Yao Qiu was also going into the secret realm with her, she became worried.
With nothing to do, Yunlan simply went into the Classic of Mountains and Seas to refine the elixir.
Yao Qiu did have the weapon, and she had reserved a long sword for Yao Qiu when she was refining the long sword before. However, it was so dangerous in the Classic of Mountains and Seas, and life-saving potions and elixirs were also indispensable.
The federal medicine is very expensive, but fortunately she doesn't need to worry about the medicine, Principal Shao and the others will take care of it.
It would be enough for her to refine some elixirs to save her life at critical moments.
But before refining the elixir, Bai Ze reminded: "Master, you might try refining a storage bag first."
"Storage bag?" Yunlan was stunned for two seconds, but did not ask what the storage bag was. After all, the literal meaning of this thing was easy to understand.
She just didn't understand why she needed to refine the storage bag.
"Isn't there a space button?" Although she doesn't have an empty button, she has the Classic of Mountains and Seas and can pretend to be a space button.
Bai Ze stopped talking and looked at Yun Lan speechlessly.
Seeing its expression, Yun Lan blinked in realization, then nodded and said, "You're right, I also think I should refine a storage bag first."
She is stupid. She has the Book of Mountains and Seas and can pretend to be a space button. It’s not like Bai Ze doesn’t know about it, but it knows it but still reminds her to refine a storage bag. This means that the secret realm is very likely to be incompatible with the Book of Mountains and Seas. When she enters the secret realm, she may not be able to open the Classic of Mountains and Seas.
"But how to refine the storage bag? I also want to refine some elixirs, is it too late?" Yun Lan asked hesitantly.
The storage bag should be the same thing as the space button. It needs to open up an independent folding space. This shouldn't be easy, right? Otherwise, why would the federal space button be so expensive?
"Of course I can in time, the storage bag is not particularly difficult." Bai Ze's tone was very contemptuous.
In the past, everyone had a storage bag, right? When touching the body, after touching the treasure, the storage bag was thrown directly on the body and taken away.
Yunlan's eyes widened. Is refining a storage bag such a simple thing?
You must know that space buttons that have the same function as storage bags are in short supply in the Federation, and the prices are sky-high.
The production technology of the Federation's space buttons has always been controlled by the Gu family of the eight major aristocratic families, and the history of space buttons in the Federation is not long, only a thousand years.
Before the emergence of Space Button, there were only seven aristocratic families in the Federation. After the emergence of Space Button, the Federation had the Gu family, the eighth largest aristocratic family.
In the Federation, a cubic meter of space button costs up to 500,000 star coins. The larger the space, the more expensive it is.
Moreover, the space button requires a very special kind of ore to be refined. Most of this kind of ore is controlled by the Gu family, and the price is extremely expensive.
I wonder if this kind of ore will also be used to refine the storage bag. If necessary, she may not be able to afford or buy this kind of ore.
Bai Ze had no idea that Yun Lan was full of worries. Time was running out, so Bai Ze didn't say anything and took Yun Lan directly to a mountain with sparse vegetation.
This mountain was very low. Yunlan recalled the full text of the Classic of Mountains and Seas and discovered that it was an unknown hill that had not been recorded.
Just when she was about to ask Bai Ze why she brought her here, she heard Bai Ze say: "This mountain is rich in an ore called space stone, which can be used to refine storage bags."
Yun Lan was surprised and picked up a silver-white stone at his feet, "Isn't this the stone you are talking about?"
Bai Ze nodded.
Then Yunlan was speechless.
The richness she thought needed to be dug and mined, but the richness Bai Ze said could be found everywhere in the mountains and plains?
Yunlan: "You made me understand the word rich again."
After speaking, Yunlan re-observed the space stone in his hand. It was very similar to the ore used by the Federation to make space buttons, but the color was more silvery, while the color of the ore used by the Federation to make space buttons was whiter.
Yunlan didn't know how much ore the Gu family needed to make a space button, but according to Bai Ze's method of refining a storage bag, only a thumb-sized space stone was needed to make a storage bag.
Moreover, the refining process is indeed extremely simple. Yun Lan, who had failed several times in refining the sword, succeeded in refining the storage bag this time.
Moreover, the storage bag she refined also has a huge space, a full ten cubic meters!
You must know that the largest space button currently available in the Federation is only twenty cubic meters!
Looking at the space stones all over the mountains and plains, Yunlan felt a little dizzy.
God, with so many space stones, how many storage bags can she refine?
Because the storage bags were really easy to refine and didn't take time, Yunlan didn't hold them back for a while and simply refined a dozen more, planning to take them out to give to Yao Qiu and Uncle Luo when the time came.
When she comes out of the secret realm, she will refine a storage bag for all the uncles and aunts of Blue Star.
This way, Cang Lanxing can have a storage bag for everyone.
After refining the storage bag to his satisfaction, Yun Lan finally started refining the elixir.
Refining elixirs is much more difficult than refining storage bags. In addition, Bai Ze is probably afraid that she will encounter any fatal danger in the secret realm, so he picks life-saving elixirs and healing elixirs that are difficult for her to refine.
Yun Lan refined the elixirs day and night for ten days. She almost wiped out many of the spiritual plants in the Classic of Mountains and Seas. However, she only succeeded in refining twelve elixirs in the end.
Yes, only twelve pills were refined in ten days. This was so inefficient, not to mention Bai Ze, that Yunlan himself didn't even notice.
Moreover, they are all first-grade low-grade elixirs, and none of them are mid-grade or high-grade.
Yun Lan was very doubtful about the effect of the elixirs he had refined, but Bai Ze was very concerned: "It doesn't matter, the first-level low-grade elixirs are enough for your cultivation level, master."
Yunlan: "·······"
For a moment, I didn't know whether to be grateful that the elixir was available, or to be ashamed of my low cultivation level.
Of course, the more elixirs, the better. Yun Lan really wanted to refine more while the secret realm was not yet opened, but she thought that the secret realm would be opened in the past two days, and it would not be a problem for her to stay in the Classic of Mountains and Seas any longer. , although she does not need to be busy with anything, some arrangements may fall on her head.
Sure enough, as soon as she came out of The Classic of Mountains and Seas, Principal Shao called her via video call and asked her to go to Principal Shao's office for a small meeting.
When Yun Lan went there, he realized that he was the last one to arrive, and the office was already full of people.
It's the same people who were at Qi's house last time, but with the addition of Teacher Anwen.
In fact, nothing was said at this meeting. They just exchanged some detailed arrangements with each other to avoid conflicts or omissions.
The First Federal Military Academy finally selected a hundred students to enter the secret realm. Among them, only about ten were freshmen. The sophomores were even fewer than the freshmen, only seven or eight. The rest were mostly juniors. Four students.
Among the dozen or so freshmen, Fu Rui and the others accounted for eight.
