Chapter 1535 How to Purify

"Purify? Where is such a method?" Chen Chengfeng answered without hesitation.

"Is there no way to purify? Then why are those top-grade wood spirit crystals you gave to Chen Xuan only 70% of the size of ordinary ones? This can only be achieved after purification." Elder Zhang said tit for tat. Their purpose is to obtain the purification method, but now the person involved denies it. Isn't it a joke that they came all the way to Wanbi City this time? Of course, Elder Zhang is more wishful thinking that this is Chen Chengfeng who doesn't want to reveal the method.

"The less impurities, the better", this is the last sentence Chen Xuan said to Chen Chengfeng. Obviously, this sentence is used to explain the question raised by Elder Zhang. Chen Chengfeng has been in contact with the wood spirit array for many years, and naturally understands the source of the top-grade wood spirit crystal. But he really doesn't know how much impurities in the spirit crystal can affect the size of the spirit crystal, but Chen Xuan knows that the fewer impurities, the better. Chen Chengfeng has never seen a top-grade wood spirit crystal of 70%, but he can only choose to believe Chen Xuan.

"Elder Zhang, you know that the top-grade wood spirit crystal is also made by the wood spirit formation. When making top-grade wood spirit crystal, the wood energy in the ground is very high, so there will be very few impurities in it. But although it is few, it cannot be completely free, so ordinary top-grade wood spirit crystal still contains impurities." Chen Chengfeng first talked about the part he already knew, and at the same time he was groping for the next "the fewer impurities, the better".

"That's true, but why doesn't the top-grade wood spirit crystal you provided to Chen Xuan contain impurities?" Elder Zhang asked.

"Yes, did Chen Xuan really take out the top-grade wood spirit crystal without impurities? What's going on? Does he have a method to purify it?" Chen Chengfeng thought secretly. Suddenly he understood a little. It must be Chen Xuan's special physique that can purify ordinary top-grade wood spirit crystals, which has aroused the covetousness of the strong men of Shenxinmen, but Chen Xuan cannot hand over this method, because he relies on his own body. If he really hands it over, it will become a machine for purifying top-grade wood spirit crystals in the hands of others.

Don't worry, Chen Chengfeng's idea is reasonable, but the fact is not like this. However, the secret cannot be leaked, so Chen Chengfeng's cognition is no different from knowing the fact. He will do everything he can to help Chen Xuan hide the secret.

"The fewer impurities, the better", but Chen Chengfeng still can't figure out how to convince others with this explanation.

Chen Xuan was anxious, and seeing that Chen Chengfeng couldn't explain the reason for a while, he could only go all out and explain it himself.

"Elder Zhang, I know why it's like this." Chen Xuan said.

"You!" Seeing that Chen Chengfeng was at a loss, Elder Zhang could only listen to what Chen Xuan said first.

"The best wood spirit crystal has impurities in the manufacturing process, and these impurities are related to the size of the best wood spirit crystal. The fewer impurities, the better the best wood spirit crystal with the same energy." Chen Xuan said.

"This is obvious. The question I want to ask is, can the top-grade wood spirit crystal be transformed without purification?"

"Of course it can. Sometimes there are many impurities in the wood energy between the earth and the ground. Although the wood energy is strong, as long as there are many impurities inside, what is produced is only ordinary top-grade wood spirit crystal. If there are no or almost no impurities in the strong wood energy, a little top-grade wood spirit crystal without impurities can be produced." Chen Xuan replied.

"Is it really like this?" Elder Zhang still has doubts. Rather than doubts, it is better to not give up.

"That's right. I remember that a book introduced it this way." Chen Xuan said.

Chen Chengfeng pretended to say: "I am ashamed, ashamed, when it comes to reading, I am not as good as my son!"

"What book? Do you still remember the name?" Elder Zhang asked.

"Well, I read a lot of books, and I really can't remember the name." Chen Xuan pretended to be embarrassed.

"Then are those books you read still there?" Elder Sun still did not give up.

"There is no way to bring those books with us! We fled from home to the central region in a hurry, and we didn't bring any books with us!" Chen Xuan's words were indeed reasonable, and even Chen Chengfeng nodded.

"Then it's really our misunderstanding. The top-grade wood spirit crystal without impurities is too important for us wood cultivators. I wonder if Boss Chen still has any in stock. If so, our Shenxin Sect is willing to pay a high price to buy it."

"No more, really no more." Chen Chengfeng said. This is the second sentence of Chen Xuan's five sentences. Even if Chen Chengfeng didn't see this, he would probably answer "no more".

"Really? Boss Chen, do you dare to swear that there are no more?" Elder Wang saw that he had nothing to gain from this trip, and he began to feel depressed and lost his good face. After all, Chen Chengfeng's cultivation was still too weak in his eyes, and he didn't take it seriously at all.

"Swear! Okay, I swear, if I still have the top-grade wood spirit crystals that the elders just had, I am willing to accept the punishment from above, just let me practice and be devoured by the inner demon!" Chen Chengfeng's face was also very unhappy, but Elder Wang was an absolute strong man, and he could not wash away the suspicion of lying if he did not swear.

"No, I want you to swear that what you just said was true." Elder Wang found that the oath Chen Chengfeng swore did not include the authenticity of whether there was a purification method, so he chased to confirm this.

Chen Chengfeng's face suddenly became ugly, but he did not refute anything, "Okay! I swear, if those top-grade wood spirit crystals were obtained through purification, I will also accept being devoured by the inner demon."

In Chen Chengfeng's mind, the top-grade wood spirit crystal without impurities must have been purified. He made this oath without considering what retribution he would get. What he thought in his heart was: What a joke. If I don't help my son, I will feel guilty in this life. It's better to be devoured by the inner demon and die?

However, after swearing, it looked at Chen Xuan again and found that Chen Xuan didn't show any special expression. "What's wrong with this guy? I made such a big oath, but this guy was indifferent. Has this son become cold-blooded? No, doesn't his son know it? He will never change. But he is not worried at all. Aren't those top-grade wood spirit crystals purified?"

Although Chen Xuan did not show an unhappy expression, he was very dissatisfied with Elder Wang's aggressiveness in his heart, and secretly remembered it in his heart. Now he and his father are unable to wash away the shame, but in the future, this shame must be washed away.

"Okay, Elder Wang, don't go too far. After all, Boss Chen is also a person of status, and Chen Xuan is his son. We will meet often." Elder Zhang is definitely an old sly guy. He told Elder Wang not to go too far after he made this oath. He really did a good job.

"No, you three came from afar to do business, and I should give you an explanation. Now it's all right, everything is clear. This time, my son is too ignorant. Because of his willful behavior, the Shenxin Sect has mobilized many troops and caused you three to run around and work hard. I must punish him well."

The three elders pursed their lips and said nothing. It seems that in their hearts, Chen Chengfeng should punish Chen Xuan well. Moreover, Chen Chengfeng should punish himself, because he shouldn't have handed over so many precious top-grade wood spirit crystals to Chen Xuan at once.

"Chen Xuan, do you want to go back with us, or reunite with your parents more?" Elder Zhang asked. In his heart, he had already determined that if Chen Xuan did not want to be punished, he would definitely ask to go back with them. But he would not take Chen Xuan with him. It was much harder for them to take Chen Xuan with them this time than to travel alone. It was because of Chen Xuan, a junior, that they did not have enough fun.

"I..." Chen Xuan pretended to be very hesitant, but in fact he had never thought about going with these three people. "I also want to spend a few days with my mother." He deliberately did not mention his father.

"Okay! Just think of this as you asking for leave to visit your family! From now on, you must arrive at the sect within a month." Elder Zhang spoke.

"Thank you Elder Zhang." Chen Chengfeng said to Chen Xuan.

"Thank you Elder, I will definitely arrive on time," Chen Xuan was calculating how long he could stay in Wanbi City!

"Elders, since you have come to Wanbi City, you can rest for a few more days, so that I can show my hospitality as a host. You are all elders of Chen Xuan's sect, and Chen Xuan will need your care in the future in Shenxinmen!" Chen Chengfeng said, but these words were not polite words.

"Okay, okay, Chen Xuan is a man of outstanding talent and the hope of Shenxinmen. We will definitely take good care of him." Chen Chengfeng stopped talking, and the three elders became polite.

Chen Xuan was eager for the three elders to leave quickly, and he still had to explain the ins and outs of the matter to Chen Chengfeng!

The three elders stayed in Wanbi City for another three days. During these three days, Chen Chengfeng was inseparable and served them personally. The three elders all felt that the trip was worthwhile. Especially before leaving, Chen Chengfeng also gave a generous gift, which was 2,000 top-grade wood spirit crystals per person, which made the three smile.

Finally, all the people who should leave have left, and only those who should stay are left. Chen Chengfeng suppressed his curiosity and didn't ask Chen Xuan about the situation. He was afraid that the three elders would come back to kill him.

Third, in the secret room, Chen Chengfeng finally asked the reason.

"Hey! Originally, this secret should not even be told to you, but now that something like this has happened, I may need you to continue to lie for me in the future. I'm afraid I can't not tell you."

"Oh! What is the great secret? Just tell me what this 70%-sized top-grade wood spirit crystal is about!"

"Come out, you may not believe it, or I will reveal the secret with action!" Chen Xuan immediately sat down cross-legged, running the "Dead Wood Art", and let seven white air enter his body at the same time. Four minutes later, a 70%-sized top-grade wood spirit crystal appeared in Chen Xuan's hand.
