"How should this door be opened?" Jiang Fei stared at the door for a long time, but he had no clue. He had used many methods, but he couldn't open it at all. He had no choice but to ask the phantom.

What surprised Jiang Fei was that the phantom actually told him the method directly: "Actually it's very simple, that is, you can turn it on by injecting two powers of immortals and demons into it."

"I tried it just now, but it didn't work at all." Jiang Fei said depressedly.

"That's because you didn't inject both powers at the same time." The phantom said lightly.

"What? You need to inject both the immortal and the demonic power at the same time. How is this possible?" Jiang Fei said with wide eyes and stared at the door.

"You are a body of immortals and demons, which should be very simple for you." said the phantom.

"It's hard to be fine or not. My body can only have one form of existence. How can you let me inject two powers at the same time?" Jiang Fei said with some depression.

"You don't understand the way of fusion of immortals and demons?" Phantom said in surprise.

"From your appearance, you seem to understand?" Jiang Fei said with some anticipation at the phantom.

At this time, Jiang Fei thought that if Phantom knew, he would have to find a way to let Phantom tell him the method of fusion of immortals and demons, so that his strength would be much stronger.

"I heard from my master occasionally mention it, but I don't understand it very much," said the phantom.

Jiang Fei seemed a little disappointed when he heard this, but he still asked: "What did your master say? Can you tell me?"

The phantom thought for a while and said, "I didn't care at that time, so I just heard some intermittently, as if I needed to combine the two forces in my body together first."

"Of course I know that the two forces need to be combined, but what I want to know is how to combine these two forces?" Jiang Fei said.

"I heard from the master that it seems that I need to combine the original power in my body first. I don't know what to do, but you can try to integrate the Nascent Souls in your body with each other." said the phantom.

"I have wanted to try this a long time ago, but unfortunately, my immortal cultivation is only in the Golden Pill stage, so I can't fusion of the two Nascent Souls at all." Jiang Fei spread his hands and said.

"My master was of the same cultivation level as the immortals and demons. When he was in the Nascent Soul God Stage, he could merge the immortals and demons' powers. When he became an immortal, he could transfer the immortals and demons' powers to each other." The phantom said.

"Hey, it seems that I have to wait until my immortal cultivation reaches the Nascent Soul and merge the two powers, and then come here again." Jiang Fei sighed helplessly and said.

"This is probably not possible. There is a ban set by the master here. A person can only enter once in his life, so it is probably unlikely if you want to come in after you leave." said the phantom.

"What? You can only come in once." Jiang Fei stared at the phantom. He was so depressed at this time. Now his immortal cultivation is only in the Golden Pill stage, while his magic cultivation has improved very quickly, and he has been in the God Transformation Stage.

But now one is the demonic Yuanying, and the other is the immortal golden elixir. He really doesn't know how to merge.

Jiang Fei looked at the black and white portal and thought that since this place was designed like this, it was obviously a great fortune specially prepared for people like him who are of immortals and demons. If he gave up this time, he might never get the fortune in the future.

Looking at Jiang Fei's depressed look, the phantom thought for a while and said, "Maybe you still have a chance."

"Did you think of something? Tell me quickly?" Jiang Fei said excitedly at the phantom.

"There is no way, but I heard from my master that it seems that the two forces can be integrated with each other during the Golden Pill stage, which is just a bit dangerous." The phantom said.

"The golden elixir can be fused. Did your master mention how to fuse it?" Jiang Fei asked hurriedly.

"I don't know this." said the phantom.

Jiang Fei thought about it and found that this phantom could not ask anything. Now he can only explore it himself. The fortune in this door was specially prepared for people with the same body of immortals and demons. He said he would obtain anything, otherwise he might regret it for life.

Jiang Fei sat cross-legged, and he began to close his eyes and ponder the method of fusion of immortals and demons. The phantom was also very sensible. He did not disturb Jiang Fei, but stood aside. Whenever Jiang Fei asked, he would tell Jiang Fei what he knew.

"Someone came to the Medicine Stone Hall again." Phantom said in surprise.

Jiang Fei quickly stood up and said, "Who is here?"

The phantom did not speak, but instead made a spell, and then a picture appeared in front of them.

After seeing the picture, Jiang Fei frowned because it was not Chi Li and the others who came to the Medicine Stone Hall, but the Seventh Elder. At this time, he looked at the Medicine Stone Hall with an excited look on his face and walked inside.

"Can you help me solve him?" Jiang Fei said to the phantom.

"This is the place of trial set by the master back then. It is fair to everyone. I have no right to interfere in their life and death." said the phantom.

Then Jiang Fei thought about it and found that the test was a life-and-death life. Although the Seventh Elder was in the late stage of incarnation, the difficulty of this test would also increase accordingly. Perhaps his worries were unnecessary, and the Seventh Elder was likely to die in the trial.

"If you can't take action, forget it. I think he should die on the trial." Jiang Fei said.

The phantom shook his head and said, "Your wish is probably going to be vain."

"What does it mean?" Jiang Fei said at the phantom with some confusion.

"The trial here has never happened to two people passing the level at the same time. Every time someone passes the level, it takes a while to recover. Now you have just passed it. The energy here has not yet recovered, so he can easily pass it, but there is no reward." The phantom said.

Jiang Fei was very depressed. Unexpectedly, he fought to the death and broke through, but now he has taken advantage of others.

Elder Seven is a powerful man in the late stage of transformation and poses a great threat to him. Jiang Fei's demon servant mark cannot be used at will, otherwise his identity will be easily exposed.

"No, I have to go out and take a look." Jiang Fei said as he was about to walk outside. He wanted to go out and attack the Seventh Elder when he was passing through the barrier to prevent future troubles.

"You have to think about it. Once you turn back, it means you give up passing the level and you will not be able to enter here again." The phantom reminded him.

Jiang Fei sighed helplessly, and at this time he could only wait quietly here.

Now it is inevitable that the Seventh Elder has entered here, and Jiang Fei is too lazy to think about it anymore. He closed his eyes and began to think carefully about the method of fusion of immortals and demons.

Jiang Fei checked many fusion methods in Shennong's inheritance. Although they cannot be used to fusion between immortals and demons, they can give him some reference and inspire him.
