All the passages on Heiluo Island are built in the mountains, and they are so complicated that if they are not warriors who have been here for a long time, it may be difficult to find the path here.

Lin Bai followed the black warrior, walked through several passages, and finally came to an underground pavilion!

"This is actually an underground ancient city!"

After Lin Bai walked out of this passage, he looked up and saw a building like an underground palace in front of him, with countless warriors shuttling back and forth inside it in an endless stream!

"This place is Black Pill City, and it is also a place to seek pills!"

The warrior in black heard Lin Bai's surprised voice and said lightly.

After saying that, the warrior in black didn't stop at all, and continued to walk forward, entering the Black Pill City.

"Are you an alchemist? Do you have certification from Tianbao Tower or Dongzhou Academy?" the black-clothed warrior asked.

"No." Lin Bai said bluntly.

The black-clothed warrior was stunned, and immediately paused slightly. Lin Bai felt that the other party seemed to be a little dissatisfied!

Lin Bai hurriedly said: "Although I am not certified, I can indeed make alchemy. As for the method of making alchemy, you will know after a try!"

The warrior in black shook his head slightly and said: "Hey, I have brought you here, let's give it a try!"

Arriving in Black Pill City, the black-clothed warrior took Lin Bai to a palace, where there was also a black-clothed warrior.

The warriors in the black market basically show themselves in black clothes, and it is rare to see the true appearance of these warriors!

The black-clothed warrior who came with Lin Bai said to the black-clothed warrior inside: "This man is an alchemist. He is not certified, but he can refine elixirs. Let's prepare some for him!"

The black-clothed warrior responded slightly and asked, "Okay, sir, please tell me your name!"

The black-clothed warrior said: "It's best not to use your real name to prevent more trouble!"

Lin Bai nodded slightly, thought for a moment, and said, "My name is... Dongfang!"

"Okay, please come with me!" The black-clothed warrior took out a jade plaque, wrote the word "Eastern" in red pen on it, and then led Lin Bai towards a passage.

Lin Bai followed.

However, he found that the black-clothed warrior who had brought him here did not follow him, but turned around and left.

Lin Bai didn't ask any more questions. He followed the black warrior to a room and pressed the jade token in his hand into the groove on the door of the room. The door suddenly opened and Lin Bai walked in. .

"Master Dongfang Alchemy, this place will be your alchemy room from now on, and the jade plaque on the door is the certificate for entering this alchemy room! Please keep it!"

"This alchemy room has all the necessary items!"

"Alchemy furnace, spiritual fire, both!"

The warrior in black came to the alchemy room and said.

Lin Bai looked around and saw that the room was not big, only about one hundred square meters. In the center of the room, there was an alchemy furnace, which was filled with a strong aroma of medicine. Under the alchemy furnace, there was a faint smell. Every little flame can be seen!

The black-clothed warrior took out a jade slip from his storage bag, handed it to Lin Bai and said, "Dongfang Alchemist, this jade slip contains the method of controlling the earth fire here and the route map to the Black Dan City. Please take good care of it." Write down!"

Lin Bai finished the jade slips, clasped his fists and said, "Thank you very much! I wonder when I can start making elixirs?"

The black-clothed warrior said: "The warriors who come to Black Pill City to ask for pills will be distributed uniformly, so just prepare well for the Eastern Pill Master!"

"I'll just quit now!"

Lin Bai was stunned and watched the warrior in black leave.

"Leaving now? The warriors in the black market are really weird!" Lin Bai watched the warriors in black leave, and there was a hint of helplessness on his face.

But at this moment, Lin Bai came to the alchemy furnace, looked up and down, then took out the jade slip, put it between his eyebrows, and immediately saw all the text in it.

"Fire Control Technique!!"

Lin Bai smiled: "It turns out that there is an earth fire vein under the Black Pill City. As long as you use the Fire Control Technique to activate it, the flames under the alchemy furnace will rise. This is really convenient!"

Lin Bai surrounded the alchemy furnace and looked it up and down. Half an hour later, Lin Bai controlled the fire control technique as he pleased without making any mistakes.

"I wonder when I can start making pills!"

Lin Bai stood in the room and said thoughtfully.

At this moment, a knocking voice came from the door of Lin Bai's alchemy room: "Dongfang Alchemist, are you there?"

Lin Bai walked over, opened the door, and saw two warriors in black standing at the door!

One of the black-clothed warriors was the warrior who sent Lin Bai to this room before. He said, "Dongfang Alchemist, are you familiar with the situation here?"

Lin Bai nodded slightly: "I'm already familiar with it and can start making alchemy at any time!"

The black-clothed warrior said: "This is the best, this friend is here to ask for elixir!"

Lin Bai looked at the black-clothed warrior beside him and asked, "What elixir do you ask for?"

"Demon Soul Pill, I have prepared the demon soul and elixir. I am willing to pay 10,000 kilograms of spiritual liquid to ask the alchemist to refine it for me!" The black-clothed warrior said to Lin Bai bluntly.

"Demon Soul Pill..." Lin Bai immediately started browsing through his memory.

In Da Mo's alchemy memory, Lin Bai found an introduction to the Demon Soul Pill.

"Demon Soul Pill, a seventh-grade elixir, uses demon soul as the main medicine and melts the soul into the elixir. After taking it, you can explode with strength that surpasses that of a warrior. However, this elixir will cause extremely serious damage to the physical body!"

"After the potion wears off, it can range from being weak for a hundred days to severe cases where all the meridians are severed!"

After Lin Bai found the introduction to the Demonic Soul Pill, his eyes shrank. This was like exchanging life for power!

The black-clothed warrior said: "I'm going to explore a secret realm, but I don't have many treasures on me. I want to refine a demon soul pill to keep in case I need it in case of emergencies. I wonder if you can refine it?"

Lin Bai nodded and said, "Okay!"

The black-clothed warrior said: "Well, I can give the demon soul and elixir to you. I will come to get the elixir in ten days!"

After saying that, the black-clothed warrior handed a storage bag to Lin Bai. Lin Bai opened it and saw that it contained the elixir for refining the demon soul pill, and a jade bottle containing a demon soul!

Lin Bai picked up the storage bag and said, "Why ten days? Just come here in three hours!"

"Three...three hours..." The black-clothed warrior was stunned and said in surprise: "Does it only take you three hours to refine the demon soul pill? Is it too short, which will affect the potency of the medicine?"

"When a friend of mine asked Alchemist Luo Tian to refine it, it took Alchemist Luo Tian seven days to refine the Demon Soul Pill!"

"Does the Eastern Alchemist only need...three hours?"

The black-clothed warrior asked in surprise.

Lin Bai said calmly: "If you don't believe me, let this matter go!"

Lin Bai returned the storage bag.

The black-clothed warrior said: "No, no, no, if Master Dongfang can refine it in three hours, then I will naturally be extremely grateful!"

"That'll be troublesome!"

The warrior in black said.
