Su Wanyue unconsciously indulged in it, and the aura in her body had risen a lot, and she had reached the peak of the sixth layer of qi training, and she was almost one step away from breaking through.

At this moment, the spirit stone in Su Wanyue's hand was taken away, and as soon as the spiritual energy was interrupted, her breakthrough came to an abrupt end.

Su Wanyue opened her eyes and looked at Chu Xinghe in confusion.

Chu Xinghe said: "Cultivation is not achieved overnight, don't rush to break through, polish the realm well." ”

"Oh." Su Wanyue hurriedly suppressed the urge to break through.

Chu Xinghe held up the spirit crystal and said, "The purity of the artificially made spirit crystal is enough, but it lacks a trace of natural Dao rhyme. ”

"If you don't want it, you can't use it for energy anyway, not for cultivation." Su Wanyue didn't care, she took out a small notebook from the storage bag, and recorded the number of spirit stones consumed on the array disk one by one, as well as the number of spirit stones consumed in the machine.

After recording, Su Wanyue was a little worried: "The loss of this spirit stone is too great, and the input is not proportional to the harvest at all." ”

Chu Xinghe took her notebook and looked at it.

Eight areas, the filter area does not use the array disk, and the five regions, each array disk, need to add fifty spirit stones at a time.

It costs two hundred and fifty spirit stones at a time.

Of the 10,000 spirit stones, only about half of them were used, producing thirty spirit crystals the size of a thumb and about twenty spirit crystals the size of soybeans, and these spirit crystals will continue to grow.

The value of the spirit crystal is not comparable to that of the inferior spirit stone, even if it is just a pseudo spirit crystal, it is also precious, what is that loss.

Chu Xinghe fished out the spirit crystals one by one, removed the Xuanbing breath, and said to Su Wanyue: "Don't worry about those gains and losses, come and try to use the spirit crystals to activate the formation, how long can it last." ”

"Okay." Su Wanyue nodded.

Put a thumb-sized spirit crystal into the groove on each array disk, and in this way, twenty-five spirit crystals are used.

She put 20,000 spirit stones into the spirit stone crushing bucket, and the formation was activated.

Su Wanyue used a funnel to calculate time.

It took about two hours for the formation to slowly stop.

And the 20,000 spirit stones have long been consumed.

This time, I got a total of five fist-sized spirit crystals, fifteen thumb-sized spirit crystals, and no soybean-sized spirit crystals.

Chu Xinghe was inevitably excited, this method was really feasible, if he used pseudo spirit crystals to cultivate, then his cultivation would be a great success.

This kind of anti-heaven means.

Chu Xinghe reminded Su Wanyue: "You know your aura extraction compressor, you know it, don't you tell the third person to know?" Your friend Lin Tangtang is not allowed to say it, and I will not tell Ziling and Senior Sister Fang, as far as the two of us know, understand? ”

Su Wanyue couldn't help but roll her eyes: "Are you really stupid?" I still understand the truth of guilt. ”

"Yes, you still tell me." Chu Xinghe couldn't help but knock her on the head with a fan.

Su Wanyue covered her head and glared at him: "You are not an outsider." ”

Chu Xinghe was slightly stunned.

Su Wanyue suddenly smiled flatteringly: "You are my boss!" ”

Chu Xinghe: "...... You're ......."

"Boss Chu!" Su Wanyue shouted again, and shouted very smoothly.

It's a fool to have thighs and not hug them.

As far as she is concerned, she doesn't know what year or month she will have to wait until she wants to make an aura extraction compressor.

One is the lack of spirit stones, and the other is that she doesn't know how to form.

To learn the formation to the level of Chu Xinghe's arbitrary change of design, there is no inheritance, no understanding, no long-term accumulation, don't even think about it.

So......

"Boss Chu, you can help take a look at this drawing."

Chu Xinghe looked at the drawings handed in front of him again, and complained casually: "You girl is really going to find something to do for me, so I don't have time to sleep." ”

The movement of his hand was not slow, and he took the drawing.

Su Wanyue smiled and said: "Senior brother, have you heard a saying that you don't have to sleep for a long time before you die, you must sleep forever after you die." What to do if you sleep so much now, there will be time for you to sleep enough in the future. ”

Chu Xinghe smiled: "It's just that you have a lot of crooked reasoning." ”

Su Wanyue retorted in a low voice: "I'm telling the truth. ”

"Okay, good, it's the truth." Chu Xinghe responded casually, and his eyes were gradually attracted by the things on the drawings.

It was a very special shaped ritual instrument, with four wheels and a box similar to a carriage, and the person sat in the box, surrounded by glass wrapping, and could see the outside.

The drawing is marked with the name of the instrument: a four-wheeled vehicle for land and air.

The rows of small letters on the left side are descriptions of each part of the car.

After reading it, Chu Xinghe quickly understood some of the principles and functions of the car.

Listed on the right are the formations that are needed.

After reading the drawings, Chu Xinghe said with a solemn expression: "Your car, it is difficult to manufacture, you have to shuttle through the forest, the size must not be too big, it must be small, if you want to fly, it must not be too heavy, but if you want to resist the attack of the demon beast, the materials used cannot be too inferior." ”

"Can that be done?" Su Wanyue asked cautiously.

She also hopes to rely on this car to show her skills in the secret realm.

Chu Xinghe said: "You can try, I haven't done such a small array yet, and it's not certain whether it can succeed." ”

"It's okay, it doesn't matter if the array is bigger." Su Wanyue didn't care.

Chu Xinghe's expression suddenly became serious: "No, the array plate is too big, and the weight will increase, your car is not dexterous enough, I will try to use Yinshan jade to make the array plate." ”

"Yin Shan Yu?" Su Wanyue exclaimed in surprise.

"yes, what's wrong?"

"Boss Chu, a million lower grade spirit stones, it's very expensive, I can't afford to sell it."

That's still the lowest price, and the auction price is higher.

Chu Xinghe chuckled and knocked on her head: "It's not promising, it's just a piece of Yinshan jade, as for it?" ”

"Why not, a million." When Su Wanyue said this, she suddenly remembered that the person in front of her was a big money, and asked curiously: "Boss Chu, do you have Yinshan jade on you?" ”

"Don't call me boss, it's not good, call me senior brother." Chu Xinghe suddenly corrected Su Wanyue.

Su Wanyue obediently shouted, "Senior brother." ”

Chu Xinghe nodded and said, "I don't have Yinshan jade on me, I gave you all the spirit stones, and I can't afford to buy Yinshan jade, but I know where there is Yinshan jade." ”

"Where?" Su Wanyue asked subconsciously.

"Follow me."

Before leaving the small courtyard, Chu Xinghe changed the formation in the courtyard again, so that except for him, no one else could enter.

Chu Xinghe said: "In and out of the card, when I come back, I will make it for you." ”

Su Wanyue nodded and asked in a low voice, "Senior brother, if it's too late today, will the elders of the Teleportation Hall let us leave?" ”

"Who said they were leaving Qingyun Academy?"

"Huh? Isn't it? ”

"You'll find out with me."

Chu Xinghe took Su Wanyue to shuttle around the academy, and the more remote she became, the more unfamiliar Su Wanyue became more and more unfamiliar with the surrounding environment.

Su Wanyue was a little curious: "Senior brother, where is this?" How come I haven't been here. ”

Chu Xinghe replied: "The inner courtyard of Qingyun Academy, of course you haven't been here, don't speak, follow my steps, don't make mistakes, there will be more forbidden formations in the future." ”

"Oh." Su Wanyue answered softly, followed behind him, walked through the inner courtyard, and gradually entered the forbidden area of the academy.
