Su Wanyue returned to the secret room in the blink of an eye.

If it weren't for the sky-blue bead the size of a goose egg in her hand, she would have thought it was just a dream.

"Senior Brother Chu, who is that beauty senior just now? Has his spiritual power really been sealed? Was he locked up there? Do you want to save him? Why doesn't he wear shoes? He ......"

Su Wanyue had too many questions in her heart.

Chu Xinghe "shh

He whispered: "Don't ask who he is, it doesn't matter who he is, you just need to know that his strength is countless times stronger than yours, and his affairs will be handled by himself." ”

Chu Xinghe said, took out the Xinglan Bead in Su Wanyue's arms again, and moved the folding fan in his hand, and Su Wanyue's hand unconsciously raised.

With a slight stroke of the folding fan, a piece of spiritual power turned into a sharp blade and cut through Su Wanyue's fingers.

A drop of blood slipped from Su Wanyue's fingertip and happened to fall on the Xinglan Bead, which suddenly floated in the air.

The sky-blue beads cracked in an instant, and then they were divided into small beads, and the small beads were strung together and flew to Su Wanyue's wrist, firmly clinging to her skin, and her figure disappeared for a moment.

After Su Wanyue recognized the Lord Xinglan Zhu, she learned its name.

The Xinglan Bead is a defensive magic weapon, and when in danger, it can resist an attack from the Yuanying powerhouse, or teleport her away.

Nine beads, you can protect her nine times.

Su Wanyue said proudly: "It is said that cats have nine lives, I am now more powerful than cats, I have ten lives!" ”

Chu Xinghe suddenly smiled, Senior Sister Su's reaction was really different from ordinary people.

Su Wanyue also knew that she had received a great favor, and such a valuable treasure was definitely not given to her by that senior because of a little joke.

It must be because of Senior Brother Chu.

Su Wanyue unconsciously asked, "Senior Brother Chu, why are you so good to me?" ”

"Repay the favor."

What? Gratitude?

"Could it be that in your previous life, you were an injured little fox demon, and you were saved by me, and you came to repay your kindness in this life?"

"Read less scripts and practice more."

Chu Xinghe shook his fan and walked out of the secret room, without revealing anything else.

Su Wanyue smiled and didn't ask again.

She thought that Chu Xinghe would definitely say in the future that no matter what reason he was good to her, she would return the favor in the future.

It is said that if you have too much debt, you don't have to worry.

owes and owes, her cheeks have thickened, anyway, owing a favor is owing, two, three or four are all owed, and it must be okay to have another one?

Su Wanyue trotted to Chu Xinghe and took out a drawing for him: "Senior Brother Chu, I heard that your formation is very powerful, can you help me see if some of my ideas can be realized by the formation." ”

"What thoughts?" Chu Xinghe took the drawings and walked to the table while looking at them.

The lines on the drawings are very regular, and the small print next to them is also in place.

Chu Xinghe quickly understood Su Wanyue's thoughts.

Su Wanyue was afraid that she wouldn't understand, so she said on the side: "I want to make a spiritual power extraction compressor, the spirit stone we commonly use, its spiritual energy accounts for a very small proportion, I roughly estimated it, it only accounts for about 20%, of course, it may be lower, and the rest is the mineral composition." ”

"I want to extract the spiritual energy from the spirit stone, and then compress it, let it liquefy, and then solidify it to become a pure spiritual power crystal, the spiritual power of the pure spiritual power crystal is huge, and the battery life is longer."

"In addition, I am going to build a fully automatic off-road vehicle, which must use this pure energy crystal."

Chu Xinghe originally wanted to say that there was a kind of spirit crystal in the cultivation realm, all of which were transformed by spiritual energy, and using spirit crystals was, why bother so much.

After thinking about it, this is Beiwangzhou, the most impoverished continent in the world of cultivating immortals, and medium-grade spirit stones are rare, let alone spirit crystals.

Besides, Su Wanyue's idea is very interesting.

In the world of cultivating immortals, no one has ever had such a bold idea.

If this method can be realized, then it is completely possible to artificially create spirit crystals, the value of spirit crystals is extremely precious, a spirit crystal can be exchanged for 10,000 high-grade spirit stones, a high-grade spirit stone can be exchanged for a hundred medium-grade spirit stones, and a medium-grade spirit stone can be exchanged for a hundred lower-grade spirit stones.

According to Su Wanyue's words, even if a hundred spirit stones can get a spirit crystal, they will make a lot of money.

Chu Xinghe understood the drawings, but in fact, to make things, it would take countless tests and researches.

He put away the drawings and said to Su Wanyue: "Let's go and sell the Xinglan Flower first, and then buy some refining array materials and refining materials, and then go back to the academy to study them." ”

"Mmmm......mmmmmm

In this way, it saves her a lot of time.

She could have handed this matter over to Chu Xinghe, and then she would research and design other things.

Kamikaze is very prosperous.

North Neighborhood Market has a huge trading area, with long streets as far as the eye can see, crisscrossed by streets, some full of street stalls, some not.

Su Wanyue and Chu Xinghe first went to Fulin Commercial Bank to sell Xinglan Grass.

Chu Xinghe had the VIP card of the Fulin Commercial Bank, and they were taken to the VIP room as soon as they went.

Su Wanyue left ten Xinglan flowers and let the little spirit plant them, and take out all the rest.

The steward counted for a while before he finished: "There are a total of thirteen thousand six hundred, one hundred spirit stones, a total of one hundred and six hundred low-grade spirit stones." ”

Su Wanyue blinked: "How much?" ”

She suddenly turned her ears back.

The steward repeated: "One million three hundred and sixty thousand lower-grade spirit stones. ”

Su Wanyue turned her head to Chu Xinghe in a daze and said, "Yes, you pinch me to see if I'm dreaming." ”

She only knew that she had harvested a lot of Xinglan flowers, but she didn't expect it to be so much.

Chu Xinghe put down the album in his hand and knocked her with a fan: "It's not promising." ”

Then, he turned back to the steward and said, "The master wants us to purchase a batch of materials to go back, and asks the steward to help us prepare one or two." ”

It turned out to be for the sect's purchase, and he said, how could two little disciples have so many spirit stones.

Su Wanyue also came back to her senses from the huge surprise at this time.

She had never seen so many spirit stones before, and she was just stunned for a while.

When she came back to her senses, she saw that Chu Xinghe was reporting the name and quantity of the materials.

Su Wanyue listened to it for a while, and felt that something was wrong, and the refining array materials were forgotten.

Why even the alchemy furnace, the spirit rune pen, the spirit rune liquid, and the elixir seeds...... Do you want these things too?

Su Wanyue couldn't figure it out, and every time she didn't ask, she let Chu Xinghe say a lot of thunderbolts, and spent all the more than one million spirit stones.

The steward is fast.

They had only been sitting for a quarter of an hour, and he had already come in with four large storage bags and said, "Two fellow Daoists, the things you want and the list are here, you can count them, and in addition, the storage bags will also be given to you." ”

"Okay." Chu Xinghe really counted the prices and quantities on the list one by one.

After making sure that there was no problem at all, he put the storage bag into his arms and said to Su Wanyue, "Let's go." ”

"Slow down, I'll send you off." The steward got up and sent them downstairs.

As soon as I went downstairs, I met Shen Yunjin and his party.
