There are even some key scenes that remind Lin Fei of some legendary secrets, but before Lin Fei could take a closer look, the scene turned into a cloud of fog.

However, Lin Fei was not in a hurry, just watching the pictures flash by. Although he didn't know how many secrets were hidden behind the fog, just knowing these things also gave him a little more or less aware of Heishantou.

First of all, this place must have a great relationship with Xuanyin Sect. Moreover, after Lu Qi achieved his true body with the help of the ghost elixir, he did not stop moving forward, but instead went further and was promoted to the realm of Dharma body.

But in the end, for some reason, he finally fell here. This immortal demon has been wandering for many years, and is now encountered by himself.

Moreover, looking at the scene in Heishantou, it seems to be quite similar to the location of Xuanyin Sect before its demise. It may be the former site of Xuanyin Sect...

However, there are many scenes in the picture, and no corresponding relationship is found here, and similar legends cannot be found in history. There seems to be a period of history hidden in the middle...

After reading these complicated history and thinking about his experience in the illusion, a vein appeared in Lin Fei's heart, as if he had grasped a trace of truth hidden behind the Black Mountain Head...

However, Lin Fei didn't bother to think about it, because as those pictures gradually disappeared, the eighteen levels of hell were about to take shape.

At this time, the acquired aura brought out by the immortal evil did not disappear, but wrapped around it like a python, swimming between the eighteenth level worlds, as if it was attached to the world, but it never integrated into it.

The eighteen-level hell has stopped growing, and is still just a prototype. Not to mention that it has turned into eighteen different big worlds like in ancient legends, even if it is still a distance of 100,800 miles from the small world.

However, Lin Fei was not in a hurry. Although the formation of the eighteen-level hell has slowed down, it is at least growing. One day, this world seed will still hatch.

At that time, I will be the lord of these eighteen levels of hell, and even if I am no less than the emperors of Yama in the ancient legend...

No matter how many secrets are hidden behind this, these eighteen levels of hell have taken root. When this place turns into a real underworld, Lin Fei is confident that he can deal with all the troubles.

Lin Fei took a step forward and left the underworld.

At the same time, Li Beixing also completed the refining. At this time, he was holding the gourd and checking carefully, and his eyes lit up.

After digesting the acquired yin energy, there are three additional restrictions on the magic weapon gourd and sword light. The most important thing is that from then on, these two magic weapons are completely combined into one, and they can be retracted from the heart. The two complement each other and the overall power is more than ten times larger.

Li Beixing looked up satisfied and suddenly saw Lin Fei appearing in front of him.

"You're back." Li Beixing nodded calmly. He was no longer surprised by Lin Fei's elusiveness.

After walking with Lin Fei until now, Li Beixing's nerves have been trained to be extremely strong. Not to mention that Lin Fei suddenly appears, even if he practices the Dharma image the next moment, Li Beixing will only say congratulations and then hold his thighs decisively.

"Forty-five prohibitions?" Lin Fei looked at the gourd and nodded slightly. If he met the Ghost Emperor, the two would not be so embarrassed. This magic weapon alone would be enough to deal with it.

"Thank you." Li Beixing bowed for the first time and thanked him solemnly.

Lin Fei smiled and understood in his heart that Li Beixing was thanking him for helping to refine magic weapons. Magic weapons were almost the second life of a cultivator. It would not be an exaggeration to Li Beixing thank him so much.

After getting up, Li Beixing hesitated for a moment and finally said, "Did you say something about immortality just now?"

"Hmm?" Lin Fei looked at him with a little strange glance. The immortal evil can only be born from the Dharma body. It is extremely rare in all worlds. Once it appears, it will be snatched by the top sects.

This is not something that Li Beixing can access, unless his sect inheritance is unique...

After Li Beixing asked this, he seemed to realize that it was wrong and quickly changed the topic: "By the way, fortunately, you took action just now, otherwise I would not be able to deal with the acquired yin energy. However, I am also a person who is grateful for your kindness. As long as you have trouble next, I will do my best."

Li Beixing patted his chest and promised that it seemed that the sword was no problem.

Lin Fei just smiled, and did not ask questions, looking around: "It just happened to be your magic weapon next. It seems that your chance to repay your kindness has come."

Li Beixing's face turned dark. Sure enough, not long after the two of them finished speaking, a piece of dust suddenly flipped up from the collapsed ruins of the cave, and then there was a strange ghost with a snake-headed body and a human-headed person rushed out of the ruins.

Although there is a ghost, its facial features are broken and its face is blurred. It only has a big mouth that reveals countless sharp teeth. The snake's body is thousands of feet long and has fine black scales on the surface. It is full of ghost energy. It turns out to be a ghost king.

And as soon as it appeared, it broke through the deep ruins and rushed towards the two of them with a terrifying power...

"Damn, where did the ghost king come from..." Just as I promised, a ghost king came up now. Li Beixing was a little speechless about his luck.

But now this formation cannot be avoided. The ghost king is coming with great momentum, and Li Beixing is also waiting for it. The magic weapon gourd is hanging in the air, and suddenly emits a thousand-foot light, like a sword, with sword energy scattered. Only thousands of lights are shrouded on the ghost. In an instant, the flesh on the ghost's body was opened, as if thousands of sharp blades were plowing over at the same time.

The sword talisman in the gourd was originally from Lin Banhu's hand, but because of the problem of weapon refining techniques, the power has not been fully exerted. Now, after absorbing the acquired yin energy, the sword talisman and the gourd are completely integrated, and the power of the magic weapon suddenly increases.

Although Lin Banhu's weapon refining technique was problematic, the sword intent was unparalleled in the world. Once there was no obstacle, it was completely unobstructed. As the sword light swallowed and spit, the ghost king had no power to fight back. After being shrouded by the third sword light, the ghost king completely lost his fierce aura and immediately crawled back into the ruins, refusing to show up for a long time.

Li Beixing was fighting hard at this time. He was about to sharpen the sword slowly with the ghost king, but when he saw the ghost king fleeing, he became even more proud. He immediately sneered, and followed the ghost king and chased him reluctantly. He instantly arrived at the deep hole where the ghost king crawled out, hung the magic gourd in the air, and thousands of lights spit out into it...

Finally, just when Li Beixing was a little impatient, two red lights suddenly flashed in the deep cave. Li Beixing was immediately delighted. This should be the eyes of the Ghost King. He finally forced out the ghost, but the next moment, countless red lights lit up...
