The sudden collapse of the surface caused the seven people present to not react, and they fell straight into a circular pit with a length of five meters and a width of ten meters.

The pit felt like a vat, and it was pitch black, as if the light on it had been blocked, with only a faint glimmer of light penetrating into it.

"Ouch, it hurts. Lao Tie didn't have any psychological preparation, so he lost his balance when he fell, and his back was close to the ground, which was the worst one among several people.

Although this height did not cause them to fall to death, under the sealing of their bodies, this height also made them feel better.

However, these seven people are also the best among people, even if they are in danger, they do not make them panic in the slightest, but they are more and more calm.

"What seems to be on top of these walls?"

You Hong opened his mouth, and also took the lead to walk to the wall in this deep pit, and only when he got close did he see that the wall was covered with incantations, and then he used his hand to ** the smooth wall full of incantations, and continued.

"Do any of you understand these spells?"

You Hong looked at Zhang Jian and the others with a puzzled expression, as if he wanted to get the answers they wanted from Zhang Jian.

"What incantation?" Akai, who was closest to You Hong, also clung to it, observing the incantations together.

In fact, in addition to observing the incantation, Akai was mainly thinking about how to climb up, but to his disappointment, the walls of this cylinder pit were so smooth that it was impossible to climb up.

But Akai didn't give up, but pulled out his manuscript and tried to knock it on the wall.

"Don't!" Qin Yu shouted.

But the sound was a little slower, and the pickaxe in Akai's hand was already tapping towards the wall.

A bell-like sound rang out.

A translucent ripple came from the wall, shattering Akai's arms and his pickaxe, but fortunately he reacted quickly enough to fall backwards to escape.

And You Hong, who was closest to him, was also a killing god who had experienced a hundred battles, and his perception was also extremely keen, and when Qin Yu shouted, he quickly retreated backwards, leaning back to avoid the attack of this ripple.

Zhang Jian and the others also had plenty of time to dodge the ripples of the shock, which could be regarded as a thrill.

After the ripples dissipated, a crystal clear pill suddenly appeared in the very center of this big pit.

Even if the energy of several of them was sealed, they could still feel the pure energy coming out of the elixir, and it was not difficult to guess that this was a high-grade elixir.

"What is this?" Akai was curious about the elixir in front of him, even though he had lost both arms.

It's just that he doesn't know the pills, because this kind of thing is not something that the native machine spirits can recognize, after all, they don't need these pills, and they won't come into contact with the pills.

"What are you all talking about? ”

Lao Tie only got up from the ground at this time, because the light in the big pit here was very weak, and he also took out a torch and lit it.

Just when the torch was lit, a gust of wind blew towards the torch, blowing the flame of the torch "flickering", so frightened that Lao Tie quickly blocked it, and then subconsciously said something.

"It's really windy here. ”

By the light of the torches, the pit was also illuminated, and everyone saw the true face of the pit.

No wonder it's dark here, it turns out that the place above their heads has been blocked, and now it is a completely sealed space, the four walls of this space are full of incantations, and there is a greenish elixir floating in the middle of it.

Qin Yu couldn't help frowning, she felt that what was emanating from this elixir was not the breath of heaven and earth, but the breath of the instrument spirit.

In other words, this elixir was refined with Akai's arms, and these machine spirits were the heavenly and earthly treasures used in alchemy here.

After Qin Yu fell into deep thought, the others also realized this problem, and suddenly fell into a state of silence.

"What's wrong? What's going on?"

Lao Tie hadn't noticed that Akai had lost his arms, and he hadn't noticed that the elixir in the middle was refined with the spirit of the instrument, and now in this situation, no one responded to Lao Tie's boring question.

"You mean to say that this is a sealed Dan furnace, and they captured us just to refine medicine?"

Zhang Jian broke the tranquility of this moment and directly said Qin Yu's worries, but after thinking about it, he felt that the logic was wrong, and continued.

"If they really want to refine us, they don't need to go to such a great deal of effort, they must have other purposes. ”

Qin Yu felt that what Zhang Jian said was also reasonable, and from the thinking just now, he analyzed a trace of eyebrows, and then said.

"It's true that this is an alchemy furnace, it's true that they have other purposes, according to their previous behavior, this should be a test, and it is still being tested. ”

After a pause, Qin Yu continued: "However, if we can't leave here, it is also a matter of being refined into an elixir. ”

Just as Qin Yu's words fell, the pill floating in the middle suddenly seemed to have a consciousness, and it flew in the direction of Lao Tie with a "boom", and Lao Tie was so frightened that he fell backwards, and then the pill also disappeared into the wall.

Lao Tie fell along with this and threw the torches on the ground, and a gust of wind blew out the torches that fell to the ground.

"Why is this wind so strong? ”

Lao Tie said as he picked up the torch and continued to light it.

These words touched Qin Yu's train of thought, and then shouted to Lao Tie, "Give me the torch." ”

"Here you go. ”

Lao Tie carefully handed the torch to Qin Yu, for fear that the wind would blow out the faint firelight.

It's just that Qin Yu grabbed the torch and let the wind blow, the flames on the blown torch swayed constantly, and the last gust of wind blew out the torch, and the direction of the wind was the location of the elixir.

Everyone also suddenly knew Qin Yu's thoughts, which meant that this Dan furnace was not surrounded by walls as they saw.

Then Qin Yu also ran to the wall, reaching out and touching the wall.

It's just that to everyone's disappointment, the walls are still walls, and they are still trapped here.

Just when everyone was disappointed, Qin Yu seemed to have entered another state, and he felt like a soulless person, his eyes were blank, as if he had blocked his self-consciousness.

Immediately afterwards, Qin Yu's hand also submerged into the wall, and then pulled it out.

"I know these spells, there are thousands of spells such as the Soul Destroying Spell and the Purification Spell. Qin Yu also regained consciousness, and then spoke.

"How did you know these spells?" Zhang Jian also felt very puzzled, after all, even a spell that he didn't know, there would be a junior of the same era as him who would know such profound knowledge.

This made Zhang Jian feel uneasy, this Qin Yu was not as simple as he imagined.

"I don't know, but when I see these spells, a lot of this type of information comes to mind, as if something that has been forgotten has suddenly been triggered. ”

This is also Qin Yu's truth, she doesn't know why she understands so many things, and then continued.

"If you want to get out of this alchemy furnace, you need to shield your self-consciousness and enter a state of selflessness, and there is only such a passage to pass through. There is about a quarter of an hour left, and this alchemy furnace will refine us, so we must hurry up. ”

After Qin Yu finished speaking, Saike also took the lead and was the first to pass through, only to see Saike disappear after directly submerging into the wall.

Entering the state of selflessness is very simple for others, but it is very difficult for Lao Tie, after all, Lao Tie, a person with no tendons, does not have so many skills at all.

Then Zhang Jian shook his head, time was pressing, so he had to use this strategy.

"Lao Tie, you close your eyes. ”

"Oh. ”

As soon as Lao Tie's eyes were closed, Zhang Jian took out a giant stick and used his strength to knock it towards the back of Lao Tie's head.

"I don't have time to explain, so I have to grieve you. ”

Zhang Jian picked up Lao Tie and followed everyone into the wall.

The giant alchemy furnace suddenly became empty, as if none of this had happened.
