When Yu Qing walked to the staircase on the second floor, he suddenly remembered something, and then sent a text message to Erica, saying that he would go back for a while and come back in an hour. Mobile M.

Without waiting for Erica to reply, Yu Qing turned around and left the pill room.

"Let's go back and take a bath first, although the warriors of the War General Realm can already close their pores and wash off the dirt on their bodies with aura, it is still not as comfortable as taking a bath. ”

Yu Qing had been in the six pill storage rooms on the first floor of the pill room for more than twenty days, and after he had browsed each room, he would go back to the small attic prepared for exchange students at Eldis University to take a shower.

"Wang!" Caesar rushed out excitedly as soon as he returned to the attic.

Yu Qing touched the dog's head and said with a smile: "Don't worry, when I'm done, I'll take you out to play." ”

This time, he brought Caesar to Eldis University, and the elixir room was not allowed to bring spirit pets in, so he had to leave Caesar in the attic.

Lou took a bath, used the aura to evaporate the water droplets from his hair, and then changed into clean clothes, Yu Qing told Caesar two more words, and then walked towards the pill room again.

Enter the pill room and walk into the second floor.

"Yu Qing, do you still want to carefully investigate all the pills on the second floor?" Erica said as she looked at Yu Qing with blazing eyes.

"There is indeed an idea. Yu Qing smiled.

Erica said helplessly: "Are some ordinary pills so good-looking, do you know what you missed yesterday, you missed Master Bernie's public class yesterday, this is a special course held by Master Bernie for your exchange students." ”

"Do you know how important this opportunity is?" said Erica helplessly.

Yu Qing shook his head and said, "In my opinion, it is more important for me to understand the history of the development of the Federal Pill. ”

Erica doesn't know what to say, if she wants to know the history of the development of the pill, can she waste the precious exchange student learning opportunity, go and look it up.

"Okay, then you can do it yourself, remember to say hello to me if there is anything, I'll go to work on other things first. ”

Among all the exchange student guides, Erica may be the easiest one, Yu Qing stays in the pill room all day, she doesn't need to explain the work, she has too much time to do her own thing.

After Erica left, Yu Qing began to 'browse' on the second floor of the pill room.

The types of pills here are much fewer than those on the first floor, and all the rooms add up to only 20,000 pills.

In fact, the more low-end pills, the more variety, because the pharmacological knowledge required for the development of low-level pills is not much, and alchemists can continue to explore, develop, and develop.

But the high-end elixir is not good, similar to the best elixir suitable for the God of War realm, each type requires a large number of elixirs, and various elixir molecules need to react with each other, and the reaction chain cannot go wrong, so the number will be very small.

It took five days, and after Yu Qing finished browsing the pills on the second floor, he walked towards the third floor.

The number of pills on the third floor is even less, and here are high-grade pills suitable for the realm of war generals, and there are only about three thousand kinds of pills.

"There should be fewer pills on the fourth floor, and the rest of the work will be easier. Yu Qing smiled, gently pinched a pill, rubbed it a few times, and then put it back in place.

Before I knew it, an afternoon had passed.

When Yu Qing was engaged in the work of browsing pills, a person walked into the pill storage room on the third floor.

"Don't move!"

When Yu Qing was about to pick up a pill, this person suddenly yelled.

Yu Qing was startled, stopped the movement of his hand, and looked up at this man, if he guessed correctly, this should be the Allen senior of Ellie's Kakou, "Excuse me, is there something wrong with you?"

Allen had light brown hair, shook it gently, and said to Yu Qing very carefully: "Don't touch it, be careful, it will explode." ”

Yu Qing's expression froze.

Isn't it, is it necessary for the pill room to be so tightly protected, and to set traps and place bombs?

But this bomb really looks like an elixir.

Yu Qing crossed over this pill and went to get another one.

Before he could touch it, Alan was startled again: "Don't move, this one will explode too." ”

Yu Qing: "......"

What treasures are hidden here, and is it necessary to plant so many bombs?

Seeing Yu Qing's solemn expression, Alan suddenly laughed: "You may not know yet, this wooden frame is all Fadan." ”

"Fadan?" Yu Qing shook his head, he had never heard of this before.

Alan explained with a smile: "Fadan is our research at Eldis University in the last three years, and the technology is relatively mature, but there is no way to mass produce it yet. ”

Yu Qing didn't understand, so he had to listen to Allen's explanation.

Alan continued: "We alchemists are dedicated to the pursuit of the medicine path, so our personal strength is not strong, and without the force to protect ourselves, it is easy to be threatened by others. ”

Yu Qing understood this truth, the alchemist's research on the pill was too exhausting, so it was difficult to have a big breakthrough in cultivation, even if the pill was used to improve the realm, most alchemists could not have enough combat experience.

It is easy to be coveted by the strong.

"In order to change this phenomenon, we started to study Fadan. Alan said.

Yu Qing asked suspiciously, "You mean to say that Fadan can increase the combat power of the alchemist?"

"That's true. Alan nodded, and said, "Usually the pills we know are basically cultivation or healing, and most of them are refined from the essence of medicinal materials...... But what if we use those extremely irritable elixir impurities, or highly toxic elixirs, to refine the elixir?"

"As far as I know, there are many highly toxic poison pills in the Federation. Yu Qing interjected.

Alan laughed, "That's different. ”

"Poison pill is also a kind of pill, it must be taken by people, or it can be crushed and released to release toxic gases to work, but Fadan does not have to be like this. ”

"Fadan is an elixir, but it is also a weapon, as long as it is detonated with spiritual power, it will explode in an instant. ”

"Imagine that a group of warriors detonate Fadan, some of which can release poison, some of which can create poisonous rain, and some of which can cause an incredibly powerful explosion...... At that time, who would dare to say that our alchemists are weak martial artists?"

Yu Qing thought about it according to Allen's words, and suddenly felt that if Fadan could be mass-produced, it would definitely affect the direction of the war in the future, and it would become another major war weapon after the battle mecha.

"No, you just said that Fadan needs to be detonated with spiritual power?" Yu Qing asked.

Alan nodded: "That's right." ”

Yu Qing's face darkened: "Then why didn't you let me touch this pill just now, saying that it would explode?"

Allen smiled, "I'll scare you." ”

Yu Qing: "......"

Really, I don't know where your sense of humor is.
