Qin Di followed the old demon in Heishan and walked all the way to the top of the mountain, gradually reaching the highest point.

There is a small palace on the top of the mountain, which looks quite old and is very inconsistent with the identity of the demon king.

The old demon of Black Mountain did not enter the palace, but walked around from the side and came to a low valley in the back mountain.

The valley is filled with yin energy, darker than the light on the top of the mountain, but there is a faint fragrance. Qin Di has never smelled this fragrance before, and it is impossible to tell whether it is the fragrance of flowers or wood.

The more you go, the more intense the fragrance becomes.

Qin Di was very curious, not knowing what was ahead, nor why the old demon of Heishan wanted to bring him here.

After leaving for about a mile, he finally arrived at the place.

Qin Di looked closely and found that there were five or six acres of fields, black soil, and red spots deep in the valley. There were golden Ganoderma lucidum. The Ganoderma lucidums had different images, some were human-shaped, some looked like cows, and some looked like chariots and horses.

The old demon of Heishan stopped, pointed in front of him and said in a deep voice: "I tell you that this is the best chariot in the sky and underground. This type of chariot is the treasure of the underworld. Just eat one, you can increase your abilities for five thousand years. However, it is only effective for our Yin Gui Sect disciples and demon cultivators, because Cheomat grew up in Daheishan and contains rich Yin-attribute spiritual power. For immortal cultivators, it is a poison."

Qin Di was excited when he heard this: "Uncle Master, you are hiding in Daheishan to plant spiritual plants? There are almost a thousand Ganoderma lucidum trees, and I don't know how long you have planted them."

The old demon in Black Mountain raised his chest and raised his head, with a proud tone in his tone, saying, "In order to cultivate these carriages and Mazhi, I racked my brains and tried all the ways! About eight million years ago, the Sanguan Emperor came to the underworld to inspect. I took advantage of their unpreparedness and stole the horse's horse's driving, poured the horse's blood into this soil, and buried the horse's corpse on the ground, so the Ganoderma lucidum in the shape of a carriage and horse grew!"

Qin Di sighed, "Oh, so that's it. There is a frustrating horse soul hidden in Chemazhi."

The old demon of Heishan walked a few steps by the field and said, "I called you here to get some chariots and Mazhi to help you bring them to my senior sister."

Qin Di shouted loudly: "Uncle Master, why don't you go to Ziweiyuan in person? You have a passage to enter and exit the underworld. How good is it to go out to get some breath?"

The old demon of Heishan shook his head: "I have sworn before that I will not leave the underworld in this life, nor will I be too far from the Black Mountain. My subordinates are all demon cultivators. If I trespass into the fairy world, I may encounter trouble. I can't find a reliable person, so I thought of you and asked you to bring this gift to my senior sister."

Qin Di frowned and said, "This thing is so precious. Besides, I practice Buddhist skills in the underworld, and I don't know when I will see my master."

The old demon of Heishan said, "You are already a seventh-level Bodhisattva, and you can't stay in the underworld for too long by the rules. These carriages and Mazhi have been formed and will not break for a while. I will use a secret method to seal it. At least 300,000 years of medicine should not work. As long as you bring it to Senior Sister Yao Ji within 300,000 years, then there will be no problem."

Qin Di thought for a while and nodded in agreement: "Thank you, uncle. I will go to Ziweiyuan and his party as soon as possible."

This is just a Buddhist clone, and it also needs to be connected with the body every once in a while, so that he can update his spiritual consciousness and not be completely disconnected. This is just like the computer software needs to be upgraded.

The old demon of Black Mountain harvested two-thirds of the car Mazhi formed on the ground, with a total of eighty-three. He carefully packed eighty of them and placed them in a black stone box. He also pasted a yin talisman inside and outside the stone box, which ensured that the medicinal properties would not be lost. The stone box was faintly shining, just like a black gem.

He handed the stone box to Qin Di and said with a serious expression: "Nephew Qin, I want you to make a vow of heaven, and you must hand over these chariots and Mazhi to Yao Ji with your own hands! Otherwise, I will be uneasy."

Qin Di held the stone box above his head, closed his eyes, and swore intently: "Disciple Qin Kuo, here he will swear here. He will hand over the items in the stone box to his master Yao Ji in person within ten thousand years. If he violates the oath, he will be disgusted!"

Then, the old demon of Black Mountain handed over the remaining three chariots, Mazhi, and said, "These three are for you. As long as you swallow them alive, you can increase your skills by 15,000 years. If you refine them into pills, the effect will be even better."

Qin Di took it, sighed in his heart, and said respectfully: "Thank you for your kind gift from Uncle Master. People outside said that Uncle Master is in the Great Heishan Mountain. As the king of all demons, I don't know how many people he killed and how many ghosts he bullied. But I didn't expect that Uncle Master is so kind. You demon king is almost the same as a Buddhist disciple."

The old demon in Heishan waved his hand suddenly: "Don't mention the word 'Buddha' to me. When I hear this word, I get angry from my heart. Demons also have Taoism. They are also monks. What is the difference between immortal cultivators? People outside are spreading rumors and slandering. You are a disciple of the Yin Gui Sect. Don't you know?"

"Yes, my disciple understand."

The old demon of Heishan took a deep breath and said, "It's a pity that I have nothing else in the Great Black Mountain. Only this little carriage can be used. Otherwise, I would like to ask you to bring more things to my senior sister."

Qin Di touched the smooth stone box in his hand and asked, "Uncle Master, what is this stone box made of?"

The old demon of Black Mountain reached out and pointed to the rock not far away: "Here, it's the stone on this mountain! After a little polishing, it will be very smooth, like jade. I have tried it and used it to hold carriages and Mazhi, which can be stored for a long time, and is better than ordinary jade boxes."

Qin Di walked forward, reached out to touch Shan Yan, and after a while, he suddenly took a breath of cold air and exclaimed: "Uncle Master, this seems to be obsidian!"

“What is obsidian?”

"Obsidian is a treasure. Uncle Master, you have become rich! From now on, even if you don't leave your home, you can still advance to the Immortal King with these immortal materials! It is even possible that you will be able to achieve great success in your magical skills and become an immortal emperor!"

When the old demon Black Mountain heard this, his body trembled slightly: "Really and false? What's the use of this thing?"

"Uncle Master, obsidian is very useful! The Buddhists use it to make Buddhist beads, which not only can calm the mind and calm the mind, but also can double the speed of becoming a Buddha!"

The old demon of Heishan snorted coldly: "I won't sell it to Buddhism, no matter how many immortal stones you can sell it! I have a grudge against Buddhism! However, you can take some back, only by giving gifts to the great monks and Buddhas can you learn advanced Buddhism."

Qin Di also said: "Obsidian is divided into many types. In addition to the low-level ordinary obsidian, there is also rainbow-eyed obsidian. It has added many color circles based on the full moon cat-eyed obsidian. Among them, ghost fairy red-eyed obsidian, ghost fairy blue-eyed obsidian, and ghost fairy golden-eyed obsidian, these are very rare, and the most precious one is ghost dark black gold obsidian..."

"I have some ghost immortals and ghost kings under my command. With this obsidian, I can see the ghost-based heavenly way clearly and increase the speed of my cultivation many times... Moreover, it also has great benefits for the disciples of the Yin Ghost Sect..."

"Uncle Master, you stay in Daheishan for many years and rarely communicate with outsiders. You may not know that the best ghost dark black gold obsidian has another name, also called 'Black Soul Stone', which is a rare treasure corresponding to 'Sky Soul Stone'..."

When the old demon of Black Mountain heard this, he almost jumped up: "I know the Heavenly Soul Stone! I have also heard of the Black Soul Stone. You said that the black Soul Stone is stored in my Black Mountain? This is a great thing! If the news leaks and causes the Immortal King, Immortal Emperor, and the Big Buddha to come to my door, I will not even be able to keep this home that I have lived in for many years!"

Qin Di said: "Uncle Master, there are many types of obsidians. Only Ghost Dark Black Gold Obsidian is the real Heavenly Soul Stone, which is good for high-level demon cultivators! As for other varieties, such as Ghost Fairy Red and Blue Eye Black Soul Stone, they are only effective for low-level demon cultivators. You can develop a batch of low-level ghost fairy red and blue eyes obsidians, or intermediate ghost fairy golden eyes obsidians, and sell them to medium-level demon cultivators. They can not only exchange resources but also not attract the covetousness of bigwigs. Why not do it?"

The old demon in Black Mountain eyes shone and said, "My nephew has a good idea! Please help me find out what these obsidians look like? Just find a few pieces to demonstrate, and that's enough."

Qin Di was intrigued, so he took out a fairy sword and dug it on the surrounding rocks.

Unfortunately, most of the things he dug out were ordinary obsidians, and there were very few real gem-level obsidians, let alone rare varieties!

However, hard work pays off. Ten days later, he still found five pieces of ghost immortal red-eyed obsidian, three pieces of ghost immortal blue-eyed obsidian, and two pieces of ghost immortal golden-eyed obsidian. Unfortunately, he has never found it. The true black soul stone, that is, the ghost dark gold god obsidian.

Qin Di didn't give up and searched for three months, released three thousand ghost immortals, dug several deep caves in the mountains, and finally found five or six black soul stones, one of which was like a small watermelon, with a diameter of at least four inches, which was priceless.

He secretly collected the black soul stone, then took the rest and walked out of the cave.

Then he cut a black soul stone as big as a baby's fist into thin slices, made three pairs of glasses, and took one and handed it to the Black Mountain Old Demon.

After putting on his glasses, the old demon of Black Mountain stood on the top of Black Mountain, turned around and looked around.

After a while, he suddenly sighed deeply: "Oh, I've wasted my time! If I had this thing long ago, I could have advanced to the Immortal King and go out to take revenge!"

Speaking of this, he looked at Qin Di intently and said, "Mr. Nephew, if you leak the news, I will not be able to get peace in Daheishan! I want you to make another swear and not mention this matter to anyone! Otherwise I will not let you go! I would rather leave you in Daheishan and be my company."

Qin Di had to make another vow to the sky and the earth. This time the vow was more specific and vicious! He knew what it meant to discover these black soul stones. If such rare treasures were handled improperly, it would be a disaster but not a blessing. If he could not get the other party's trust, he would be imprisoned here and would never be able to go out for the rest of his life.
