After the explosion stopped, Yu Qing lowered Erica off her shoulder.

Looking up at the alchemy room that had been destroyed, Yu Qing's eyebrows furrowed: "The power of this Fa Dan is indeed much stronger than simply using the Nether Evil Qi attack, even if a strong person in the God of War Realm is hit head-on, it is estimated that he will be seriously injured, but why does the refining process go wrong?"

"It shouldn't be. ”

"What's wrong?"

When Yu Qing was refining the Fa Dan, everything went smoothly in the early stage, but when it came to the later stage of the Condensing Pill, the Netherworld Qi suddenly became extremely unstable.

But the power - I don't really have to say.

It's terrifying.

The refining of Fa Dan failed, and Yu Qing was not in the mood to continue refining Hui Yuan Dan.

In the final analysis, Yu Qing just regarded the alchemist as a side job, and the pill was not of much help to his cultivation, and the reason why he was so active in refining the Fa Dan was just because the Fa Dan could increase his combat ability.

"Erica?" Yu Qing sighed, feeling that he had to change his mind.

At this time.

Erica was covering her mouth with her hands, her eyes unblinking, as if frightened, some black flames were burning on the ruins formed by the explosion of the alchemy room.

The explosion was so loud that it attracted many people around, all of whom were fighting the fire, but the black flame could not be extinguished at all, so they could only wait for it to slowly extinguish.

"Yu Qing, what kind of magic pill have you refined, and how can the power be so powerful?" Erica looked at Yu Qing in horror and asked in a low voice.

Yu Qing shook his head: "It's just a normal burning pill, but I don't know why the reaction hasn't been stable." ”

Erica: "......" is normal, you're big.

Looking at Yu Qing's side face, Erica felt that she couldn't understand this boy a little. At the beginning, Erica felt that Yu Qing was the kind of alchemist who did not seek advancement, but now, the talent and ability displayed by Yu Qing made Erica's heart flutter.

"Erica, I destroyed this pill room, and if I need compensation in the future, I will bear it. Yu Qing said to Erica.

The alchemy room was applied for by Erica with her campus account, and now it has been completely destroyed, and Yu Qing doesn't want to trouble Erica.

Erica shook her head, smiled slyly, and showed her snow-white teeth: "Why do you want to compensate, the school still has to compensate me, the quality of the school's alchemy room is so poor, it affects my refining of pills, it's already a good thing that I don't complain about them." ”

Yu Qing was stunned and asked, "Can you still do this?"

Erica smiled, "Of course, I'm a consumer. ”

"Okay. Yu Qing breathed a sigh of relief, since there was no trouble and he didn't have to be responsible, he didn't have to worry.

"Let's go, the disposal of the ruins is in the responsibility of the school's special department, and we don't need to interfere. Arakar said.

Yu Qing followed Erica back, a little silent.

Although the refining of Fa Dan failed this time, the power displayed by Fa Dan made Yu Qing's heart flutter.

One way or another.

This Fadan must be refined by itself.

"Erica, can I visit the Yaosheng Stone?" Yu Qing suddenly stopped and asked Erica.

Every exchange student had another opportunity to visit Yaosheng Stone, and Zhou Anhai also specially told Yu Qing not to miss it.

Since there was a problem with the refining of Fadan, Yu Qing felt that he might as well visit the Yaosheng Stone.

The medicine stone can help the alchemist to have an epiphany, and I don't know if it can help him.

"You haven't used up your chance to visit the Yakusheng Stone yet. Erica looked at Yu Qing and suddenly said, "You didn't stay in the pill room, you stayed in the dormitory to study the pill, and you definitely didn't use it." ”

"You just have to apply to the school and you can visit. ”

"Hmm. Yu Qing nodded lightly, and used his temporary pass card for Eldis University to contact the school and apply to visit Yaosheng Stone.

Soon, the application was approved, and after getting permission, Erica took Yu Qing and walked towards the location where Yaoshengshi was.

"Yu Qing, I hope you can get enough knowledge in the Yaosheng Stone. "Road, Erica sincerely wishes Yu Qing.

Yu Qing was puzzled, his eyes looked directly at Erica, and asked, "What does it mean to get knowledge from the Yaosheng Stone?"

Erica's lips were slightly upturned, ruddy, and she laughed softly: "You don't know yet, many of our Federation's alchemy techniques and pill formulas are obtained from this medicinal stone. ”

"From the Yaosheng Stone?"

"yes. Erica nodded, and continued: "According to our research, in ancient times, those Qi Refiners didn't seem to use letters or letterheads, except for a few Qi Refiners who had a preference for using ancient books to record things, most of the ancient Qi Refiners used jade to record things. ”

"You're talking about spirit crystals. "Yu Qing knows that this kind of thing is a very divine jade, and the martial artist can engrave the information with his spiritual power, and most of the exercises and knowledge that the Federation has obtained from the ruins are obtained in this way.

"Could it be that the Yaosheng Stone is a spirit crystal?"

"Probably a type of spirit crystal. Erica said, "But I can't be sure, although this medicine stone stores a lot of alchemy knowledge, it is very difficult to obtain it. ”

Several teachers at the school suspected that this was an item used by the ancient alchemist to test disciples and pass them on. ”

Yu Qing smiled: "Hearing you say that, I'm really a little better." ”

Erica took Yu Qing and quickly came to the place where the medicine stone was placed.

This is a building built on the top of a mountain, and it is very heavily guarded, and there are at least a dozen warriors inside and outside the building.

This is within the Eldis University School, and the safety factor is already very high, and at this moment, there are special warriors guarding it, which shows that Eldis University attaches great importance to this medicinal stone.

Yaoshengshi is the foundation of Eldis University, which is different from the 'library' nature of the Dan Medicine Room, which is the real foundation of Eldis University.

After passing the safety certification, a famous martial artist came forward and said to Yu Qing: "According to the regulations, you can feel a day's time in front of the Yaosheng Stone, and I will take you in." ”

Yu Qing waved his hand at Erica and said, "Erica, you go back first, and I'll contact you when I'm done." ”

Saying goodbye to Erica, Yu Qing followed the warrior into the room containing the medicinal stone.

After entering the closed room, the warrior did not follow in, but closed the door, leaving Yu Qing alone in the room.

There wasn't much in the room, it was empty, and the carpet was erected with a white jade stone that was more than a man tall.

This is a medicine stone.

"I don't know if I'll be able to get all the knowledge after breaking this thing down. ”

Yu Qing suddenly remembered this thought.

Pity.

There is no way to do that.

There is a sophisticated monitoring device in this room, and I can't do it myself, even if I want to knock down the next piece to disassemble it.

I can only do it.

Before leaving, sit in front of the Yaosheng Stone, release your spiritual power, and probe into it.
