"The princess rarely likes it, and the old fairy must teach her, knowing everything and saying everything." Taishang Laojun led Lin Du to the cabinet where his alchemy raw materials were placed.

He introduced them one by one, they were all precious medicinal herbs, and they were not interesting.

Lin Du asked, "Forgive me, I like to delve into some strange things lately. Do you use any special and interesting things as raw materials for alchemy? No matter how you look at it, they are all medicinal herbs. ”

"Something interesting......" Lao Jun fell into deep thought.

The Emperor of Heaven helped Lin Du play a round: "Don't blame you, my daughter is spoiled by me." ”

"Your Majesty is serious." Taishang Laojun stroked his beard, and he thought for a while, "Lao Xian usually uses these precious medicinal materials for alchemy. If you want to talk about something special, there are some. ”

"Oh, what is it?" Lin Dui's eyes were full of anticipation.

Taishang Laojun's face was kind: "The old immortal recently discovered that the use of fire crow feathers to make alchemy, the elixir can greatly enhance the skill. There are also golden head phalanges, which can greatly increase the tonic ability of the elixir. ”

"Oh." Lin Du was a little disappointed.

She turned to say: "Lao Jun, since this fire crow feather can be used as a raw material for alchemy, can the immortal peaches we eat on weekdays, the jade liquid we drink, the dragon scales on our father's body, and even the stones in the heavenly realm also be alchemy?" ”

She can't ask directly about the stone, because she can't reveal her purpose, so as not to cause panic among everyone.

Taishang Laojun hurriedly said, "Princess, you are really whimsical, how dare the old immortal use dragon scales to refine the pill?" That's disrespectful. ”

The Emperor of Heaven helped Taishang Laojun in vain, "It's okay, it's okay, if you just ask casually, Laojun doesn't have to take it to heart." ”

Lin Du saw that Taishang Laojun only took out the dragon scales, and did not say that it was related to stones, so she rekindled her hope: "Laojun, can stones really be used for alchemy?" ”

"The princess is really smart and different from ordinary people." Taishang Laojun smiled, and the wrinkles on his face were all squeezed together, "Lao Xian once heard Lao Xian's master say that there is a kind of stone in the heavenly realm, which has existed since ancient times, absorbing the aura of heaven and earth, and can be used for alchemy. ”

"Do you have this kind of stone, old man?" Lin Dui's heart was pounding.

Taishang Laojun sighed slightly, as if he was recalling the past: "This kind of stone is extremely rare, and the old immortal's master only has three pieces, and he used one piece to add to the raw materials to refine a Guiyuan Dan, but the effect is not good." The old immortal is not proficient in learning, and he is not as good as the master of the old immortal, and he will not use this kind of stone for alchemy, and this kind of stone has been put away, if it is not for the princess to remind him, the old immortal will almost forget it. ”

Alchemy with spirit stones? Lin Du felt a pity, but he was also very lucky, this plane actually had spirit stones.

She smiled and asked Taishang Laojun: "Laojun, I want to see the appearance of this spirit stone, can you find me to see it?" ”

Taishang Laojun waved his sleeves, and the dark grid in his hall opened, and he walked over, "After the old immortal's master passed away, the old immortal put these two spirit stones in the pavilion to prevent seeing things and thinking about people, and causing sadness." ”

Lin Du followed Taishang Laojun and walked over, and there were two stones lying quietly in the dark compartment, the size of a palm, which looked no different from ordinary stones.

Taishang Laojun seemed to see Lin Du's thoughts, and smiled: "Princess, don't underestimate these two stones, they are the products of the right time, place and people. ”

"That's amazing." Lin Du gently stroked the two cold stones, "Then they must contain a lot of spiritual power, right?" ”

When Taishang Laojun heard this, he was very sorry: "Although this spiritual stone was produced by absorbing the spiritual energy of heaven and earth for trillions of years, the spiritual power in it is not high, it is very low, and it is not as much spiritual power as a fairy peach." My master didn't believe it, so he refined a piece and found that the spiritual power contained in it was really low. ”

"How so?" Lin Du and the Heavenly Emperor glanced at each other.

Although it is not very satisfying, it is already very good to be able to get the spirit stone, and there will always be a way to inject spiritual power into the spirit stone.

She knew that this was a relic of Master Taishang Laojun, but she still had the courage to make a request: "Laojun, can you lend me these two stones for research first?" ”

Taishang Laojun's face was embarrassed, but the Emperor of Heaven said a lot of good things, and Lao Jun reluctantly agreed.

Lin Du thought that if he found a way to use the spirit stone, it would be good to tell all the truth and discussion when the time came, and I believe that Lao Jun would understand.

Back in the Heavenly Emperor's Palace, Lin Duan sent a message to Yu Xiu and called Yu Xiu back to study the spirit stone.

She sent a message to Chen Yuanzhi in her mind again, "Yuanzhi, I have found the spirit stone, but there is very little spiritual power in it, how did the immortal cultivation interface you mentioned before do?" ”

Chen Yuanzhi had already found out: "The spirit stones of that plane contain a lot of spiritual power, and they can directly construct enchantments, which is very different from our situation." ”

"You can help me check, it's really not okay to ask Mr. Xue, what should the spirit stone do so that it has enough spiritual power to construct an enchantment that is integrated with the plane?" Lin Du was in a good mood now, and she felt that she had seen hope.

Chen Yuanzhi responded: "Okay, I'll check." ”

In the Heavenly Emperor's Palace, Lin Dui, the Heavenly Emperor and Yu Xiu studied for a long time and didn't figure out what the spirit stone was and how to play it.

Looking at these two stones, Lin Duan suddenly remembered the Soul Suppression Lamp, "Father, can you see if the material of this stone is similar to the Soul Suppression Lamp?" Do you know the origin of the soul lamp? ”

The Heavenly Emperor and Yu Xiu carefully examined and rubbed the two stones.

The Heavenly Emperor nodded: "It is indeed somewhat similar, but the Soul Suppression Lamp has been carefully polished." The Soul Suppression Lantern has existed since the existence of the Heavenly Realm, and it was used by the first Heavenly Emperor to suppress the ancient fierce beasts, as for where it came from, there is no fixed statement, it is just some legends. ”

"Your Majesty, Princess Ruoli, this monarch has also heard of some, some say that the soul lamp was given by your first Heavenly Emperor His Majesty in a dream, and some say that His Majesty the Heavenly Emperor picked it up from the end of the heavenly realm."

"yes." The Emperor nodded, "It's all nonsense. ”

"Why don't we go through those ancient books and look for them?" Lin Du still thinks that reading books is the most reliable.

Finally, after the three of them sat in the library pavilion and rummaged through the mountains and books for three days and three nights, the Emperor finally found it.

He held up the dusty ancient book, "Found it!" ”

Lin Dui and Yu Xiu surrounded him, and Lin Dui asked with concern and anxiety, "Father, how is this classic recorded?" ”

The Emperor of Heaven began to tell the story: "It is said that when the First Emperor fought against the ancient beasts, he found that the ancient beasts were all eaten with a kind of stone as a supply. The First Emperor discovered that this stone had infinite spiritual power, and after the ancient beasts ate this stone, they could construct an enchantment that no one could break. ”
