"Old. ”

Mu Chen came to the simple room, knocked on the door, entered, and bowed.

"Mu Chen, what is the matter, on top of cultivation, and encountering problems?"

The old man withdrew from the cultivation state, and looked at Mu Chen with eyes as deep as a galaxy.

"Well, the student came to pay the price of the heavenly and earthly treasures that Xu Guanghui spent. ”

Mu Chen took out a storage ring and handed it to the elder.

The old man was a little surprised, Mu Chen didn't choose to exchange it on the conditions, which was unexpected. The spiritual sense probed into the storage ring, and the boss was shocked, and his body unconsciously took a step back.

After making sure again, he settled down and asked Mu Chen: "Where did this thing come from?"

"The pure Heavenly Dao crystals left by the fire spirit are of great benefit to breaking through the realm and comprehending the heavens and the earth, I don't know if this can be exchanged for ten thousand perfect spirit stones?"

"Mu Chen, do you know the true value of this Heavenly Dao Crystal?"

"I don't know. ”

Mu Chen's heart sighed, could it be that he underestimated the value of this pure Heavenly Dao crystal?

"Such a treasure can be found but not sought. Wood dust? When you have gathered enough 10,000 spirit stones, come and find me again. ”

In the eyes of the elder, although he was shocked, he did not see greed, and he regretfully retreated to Mu Chen, and said resolutely: "Integrate this Dao crystallization into the sea of spiritual consciousness? Integrate into the dantian, and can be advanced to the heavenly way of distraction. This is a gift from the fire spirit? I can't ask for it. ”

Well, Mu Chen was stunned for a moment, and really underestimated the value of this pure heavenly dao crystal.

Mu Chen took back the storage ring, took out another storage bag, and handed it to the elder. Inside, there are three thousand Heavenly Dao crystals. According to the value, it should not be less than 10,000 perfect spirit stones.

"Elder Order, please keep it secret and make a heavenly oath. I can use the demon body to refine it, so it's not a rare thing, so please accept it. ”

Mu Chen thought about it and decided to leak this news to the Elder Destiny so that he could talk about the matter of the fifth-order spiritual eye next.

"Huh, wood dust? ”

The old man's eyes widened in disbelief. Then he realized the seriousness of the problem and made a very heavy oath to heaven.

Throughout the ages, hundreds of ways have been studied for the development and utilization of demon bodies and demon inheritance crystals, but Elder Ming never imagined that someone could turn the demon body into a heavenly crystal.

However, combined with the Heavenly Dao Light that Wood Dust could destroy the Ink Spring, Ming Lao felt as if he understood something.

"Really?"

"Uh-huh. Thirty Dao Yuan Infant Peak Demon Shell or Inheritance Crystal? can be exchanged for a Heavenly Dao Crystal. ”

Mu Chen gave a detailed exchange rate, and the black heart increased the price thirty times.

"So cheap? ”

"It's true. ”

Mu Chen took out another storage bag and handed it to the elder, which contained 10,000 Heavenly Dao crystals.

The veteran ordered the demon body and demon crystals accumulated in the academy to convert them slightly, and his eyes lit up, and the light of wealth was condensed in his eyes.

If there is such a large number of resource bonuses, it will not be a problem for the school to have three more combinations.

Millions of years of accumulation, countless waves of demons, and the number of demonic inheritance crystals that have been accumulated is very impressive.

"Muchen, I want to do a business with you. ”

"I want to do a business with you, too. ”

"Then you talk about wood dust first. ”

"The student wants to trade a fifth-order spirit eye and place it in the cave sky. ”

"Little things, small business. Do you know how many demon crystals and shells have accumulated in the academy?"

Mu Chen shook his head, unable to estimate in his heart, it must be a huge number.

"By the way, how many Heavenly Dao crystals can you transform in one day?"

The elder calmed down and asked.

"If the Demon Inheritance Crystallization is enough, the minimum can be converted into 10,000 a day, and the highest is due to the lack of raw materials, I haven't tried it yet, and I don't know the bottom line. ”

Mu Chen gave an answer that made the old man jaw-dropping, coughing, and his Dao heart almost collapsed.

Today, with a life span of nearly 3,000 years, the Dao Heart has long been as stable as a mountain, Mount Tai has collapsed in front of him, and the face of the old man who has not changed his face has lost his temper many times, as if he was just starting out.

The elder coughed lightly twice, recited the meditation mantra hundreds of times, and forced him to speak calmly: "Are you sure?"

"Uh-huh. ”

"Mu Chen, this transaction between me and you is the crystallization of the Heavenly Dao, and it is calculated at a minimum of 10,000 per day, so as not to affect your cultivation. I will provide you with 300,000 Heavenly Dao Crystals of the Yuan Infant Peak? You are responsible for providing me with 5,000 Heavenly Dao Crystals, which will be divided into fifty and fifty parts, do you agree? ”

Muchen groaned, then agreed.

"Sign the contract. ”

"Uh-huh. Can the Heavenly Dao Crystallization be exchanged for a fifth-order spiritual eye?"

"Yes, the price of a fifth-order spiritual eye is equivalent to 300,000 Heavenly Dao crystals. ”

Mu Chen nodded, agreed, and was happy in his heart, such a price was like a free gift for Mu Chen.

This time, the advantage is too big.

In Mu Chen's heart, a bold idea emerged, arranging a formation in the cave sky, burying the pure heavenly dao crystals, and turning the cave heaven into a perfect cultivation place.

The old man left a stick of incense and handed a storage ring to Mu Chen.

Mu Chen penetrated into the spiritual sense, and there were nearly a million Demon Inheritance Crystals at the peak of the Yuan Infant and a sealed fifth-order spirit eye. Mu Chen's eyes lit up and he bowed in thanks.

"Three days later, I'll deliver the goods, and I'll be old. ”

"Okay, I'll wait for you. ”

Mu Chen left, and ordered the elder to put the three thousand heavenly dao crystals into the treasury of the school.

As for the transaction, the elder did not mention it to anyone, and it was a secret between the two.

Returning to the Xuanwu class, Mu Chen entered the cave and exchanged all the demon inheritance crystals for heavenly path crystals. Millions of Heavenly Dao crystals, wood dust was transformed into eight pure Heavenly Dao crystals. The other 20,000 Heavenly Dao Crystals were stored separately and handed over to the Elder after three days.

Mu Chen was busy in the cave......

In the Spirit Master Academy, the anxious magma dragons, white elephants and other demon beasts received an order from Tianlong: From now on, all demon beasts will completely withdraw from the Spirit Master Academy.

In order to ensure that the peach fairy root after March can fall 100% into the hands of demon beasts, it is necessary to conduct intensive training for all students to improve their strength.

A spirit body of the Heavenly Dragon, without any scruples, descended to the Spirit Master Academy, oppressing the mentor and students.

Because of the guidance of Xu Guanghui, the master of the Spirit Master Mansion had no time to clone himself, and he was ordered to exude momentum, but he was slightly inferior to Tianlong, so Tianlong was able to show off his might in the Spirit Master Academy.

"Ordered to be an old ghost, all the students of the Demon Beast Department have withdrawn from the Spirit Master Academy. ”

As soon as the words fell, Tianlong sensed the danger in the dark, and hurriedly swept away all the demon beast students.

In the next second, a brilliant sword light carrying fierce killing intent bombarded the place where Tianlong had been before. If the Celestial Dragon hesitates for a second, then this spirit body will remain.

The Pan Tao Immortal Root Event? The old man muttered and convened the class teachers to discuss the matter.

"There is no limit to the number of people in the Pan Tao Immortal Root Festival, how many students will be sent to my Spirit Master Academy this year?"
