It's night.

Liu Yu sneaked into the inner room and turned on the stealth technique, but no one found him at all, the location of the inner room was relatively hidden, if it wasn't for the route that Yang Xiu told him, he estimated that it would take a lot of time.

The furnishings in the inner room were simple, and there was not even a valuable ornament, Liu Yu just glanced at it, walked straight to the table inside, counted the lattices, and turned the copper tripod of the fifth lattice clockwise.

In an instant, the wall next to the bookshelf opened, and Liu Yu was immediately overjoyed, this was the place, the stairs inside were dim, and he couldn't see the road clearly.

The moment he stepped into the stairs, the wall lit up with fire, and all the way down, Liu Yu hurried down with the light.

It didn't take long for Liu Yu to see the place in the basement that looked like the main hall, which was different from the outside, there were some stone tables and chairs, and there was a table table, on which the statue of Shennong was enshrined.

According to legend, Shennong tasted a hundred herbs and was also the originator of pharmaceutical alchemy, but it was the first time he saw the statue of Shennong, and it was in such an underground secret room.

The candle flame on the table was beating, but there was no one around, Liu Yu cautiously approached the statue of Shennong, and slowly reached out to touch the base behind the statue of Shennong, and sure enough, he touched three raised bolts.

This is also what Yang Xiu told him, the three bolts must be turned in order, otherwise the deadly mechanism will be opened, and once the mechanism is opened, there is no possibility of getting out alive.

Liu Yu is here to steal the antidote, not to die, starting from the first one on the right, then the far left, and finally the middle one.

Turning the bolt, Liu Yu waited quietly for a long time, did not open the mechanism, the order was right, and the hanging heart was put down.

Suddenly, the desk automatically moved to the side, and there was a pitch-black passage under the desk, just like the way he entered the secret room just now, and as soon as he went, the torch on the wall was instantly lit, which also saved him time.

Below the secret room is a stone room, similar to the place where the statue of Shennong is enshrined, but there is no such thing as a god statue here, and the layout is simpler than the secret room, except for the tables and chairs made of stone, there is nothing else, and even the teapot on the table is empty.

The tea brewed in it was also dry, Liu Yu looked around, the walls and the ground were also made of stone, but when he got here, Yang Xiu didn't tell him what to do.

Looking at the situation here, there is no antidote here, or there is a mechanism somewhere in this stone room, Liu Yu knocked on the stone wall, and found nothing unusual.

Tables, chairs and teapots are not organs, Liu Yu is a little anxious, if he can't find the antidote, Yang Xiu will have to die, then he has spent so much effort to save people, and his previous efforts will be wasted.

"Ahh A roar of rage and despair was heard, like behind the stone wall on the right.

Liu Yu followed the voice and walked over, but he didn't know how to pass, just when Liu Yu was helpless, a door opened on the stone wall, and an old man with white hair walked out, with tattered clothes, exuding a strong smell of medicine, full of anger and unwillingness.

When I walked to the table and picked up the teapot, I found that it was already empty, and immediately threw the teapot to the ground in anger, and the teapot fell to pieces in response.

Liu Yu was invisible, he didn't find Liu Yu, he still thought that there was only him here, the old man sat at the stone table, suddenly grabbed his hair and roared: "How can you fail?" How can it fail? ”

In stealth, Liu Yu thought, this old man has a strong smell of medicine, and the stone wall may be the place where the antidote is really hidden, Liu Yu was afraid of alarming the old man, so he walked carefully behind the stone wall.

Behind the stone wall is another scene, all kinds of tools for refining medicine and pounding medicine are readily available, and there are several wooden shelves next to it, which are full of various small bottles, with notes on the bottle body, and the names of the medicines are written on them, Liu Yu read the names on each bottle of medicine, but there is no antidote to Yang Xiu.

Liu Yu couldn't help but curse in his heart, Lu Xun shouldn't have the antidote with him, right? There are so many medicines, and not a single bottle is an antidote.

But after thinking about it, since Yang Xiu asked him to come here, there shouldn't be anything wrong, Liu Yu thought of this and walked out and went up the steps.

As soon as he stepped on the steps, the torch lit up, and Liu Yu took the stealth technique, pretending that he had just walked down from it.

Seeing Liu Yu, the old man was instinctively vigilant, stood up and retreated to the door of the alchemy room, staring at him, Liu Yu was also secretly worried in his heart.

From the statue of Shennong in the secret room above, to the alchemy room here, to this old man who looks a little crazy, he must be an alchemist, and the antidote should also come from his hands.

The old man seemed to regard him as Lu Xun's subordinates, and his attitude towards him was very indifferent, seeing that he didn't move, he turned around and went back to the alchemy pharmacy and began to tinker with a bunch of medicinal herbs.

"I'm here to get the antidote, for the traitor I just caught, and the boss said that I can't let him die like this." Liu Yu pretended to be Lu Xun's subordinate and said.

The old man snorted coldly, did not answer, and continued to tinker with the medicinal materials in his hand, Liu Yu saw that he did not answer, and he was also very anxious, no matter what, he had to get the antidote.

"You can't make an antidote, right? Then you just wait for the top to serve you well. Liu Yu said with a sarcastic look, he didn't know if the agitation method was useful to this person.

After waiting for a long time, the old man still didn't say a word, walked to the Dan furnace and stared at the Dan furnace with his eyes, sometimes happy, sometimes frowning, all Liu Yu's tricks were completely useless when used on him.

"The system prompts that completing the alchemy task can obtain primary alchemy and increase some pill products."

The voice in his head made Liu Yu almost vomit blood.

"This person didn't react at all, what kind of alchemy is he taking? Does it count as alchemy for him? Liu Yu turned his back and asked in a low voice.

"Yes." The system answered very simply.

The old man was already guarding in front of the Dan furnace, in order to complete the task, Liu Yu took a fan and fanned the Dan furnace, the old man looked at him noncommittally and did not stop him.

Liu Yu thought in his heart that this elixir should be refined quickly, maybe the old man would give him the antidote as soon as he was happy, and it would save such a waste of time.

I don't know how long later, the old man opened the pill furnace, took out a black pill from the furnace with a smile on his face, looked at it carefully for a long time, and then threw it into his mouth.

Liu Yu looked at him like this, slightly stunned, he didn't expect him to be able to test the medicine for Lu Xun, no wonder he refused to say a word to himself, it seems that every time he comes to see him, it is Lu Xun or Lu Xun's henchman.

"The task is complete, the primary alchemy has been opened, and some pill products have been added." The voice of the system came again, Liu Yu checked the primary alchemy technique in his mind, and there was no alchemy to refine Yang Xiu's antidote at all, Liu Yu was a little lost, and he didn't notice the strangeness of the alchemist.
