"It's a silica mine" Ye Sheng didn't sell Guan Zi again this time, although she had already discovered the source of the spirit stone and verified it herself. Unfortunately, even under the influence of the space-time wheel, it took decades to convert a part of the finger-sized silica placed on the spiritual vein into a spirit stone. It may take thousands or tens of thousands of years to say that it is placed in the outside world, but the premise is that it must also be placed on the spiritual vein.

"No, you can't be talking about the silicon that is second only to oxygen on the surface of the earth, right?" Although Bai Xuan had already guessed that this ore converted into spirit stone should not be a rare preparation, she was still shocked when Ye Sheng revealed the answer.

"That's right, it's very unexpected, I couldn't believe it when I first found out" Ye Sheng shrugged, this secret was only mentioned to that person, as for the others, it was useless to say it, but it was empty to rejoice, people in the fairy world didn't like to do that kind of thing that could only benefit future generations.

"Yes," Bai Xuan replied honestly, "I didn't expect that the things that were used for glass in my previous life could become currency here. ”

"That's just one of the uses, I've experimented with crystal, agate, quartz, etc., and presumably the production of spirit stone is ultimately related to the element silicon. Ye Sheng said that there are only a few things she can do in this environment, and she was not a science student who was very good at mathematics, physics and chemistry in her previous life.

"In that case, people here should be very easy to find out, right?" After all, silicon is very presence, almost everywhere, and it has existed in places with aura for tens of thousands of years.

"Aren't those spirit stone mines just that?"

"I mean places other than those spirit stone mines," Bai Xuan was speechless. "There should also be a certain amount of production of crystals in the anti-world, if some of them are converted into spirit stones after a long time, as long as there are people who have a heart, they will attract some attention. ”

"I also know that it won't be that simple," Ye Sheng replied, "These silica stones will only gradually change after the aura concentration reaches a certain level, and there will be no changes in other cases." ”

"This is the reason why spirit stone mines are only produced near the spirit veins?" Bai Xuan suddenly realized.

Ye Sheng nodded, "Even if silica is found near the Spirit Stone Mine, it will be ignored because of its commonness. ”

"Do you mean, as long as we find the silica mines, and then put them into my book god realm, and make the spirit stones ourselves?" she somewhat understood Ye Sheng's intentions when he told her about this.

After all, the true aura in the book god realm is much more powerful than the aura generated by the spiritual veins. Especially the powerful aggression that is different from ordinary aura.

"That's right, after going to the Valley of Illusions, we can find time to test it, if the effect is significant, everyone will naturally be happy, and if it's not obvious, it won't hurt, just continue to put it in your book god realm. As far as Ye Sheng herself is concerned, she is still very confident in the true aura in the Bai Xuanshu God Realm, but she just doesn't know how far they can compress the time for transforming spirit stones.

"That's fine, let's do it after this experience, fly to the peak now to collect some, and just buy some crystal agate and other jewelry before going back tomorrow." The more Bai Xuan spoke, the more excited she became, and she couldn't wait to see the results.

Ye Sheng smiled silently, but he didn't object. The two talked late into the night, and finally fell asleep after they calmed down.

The next morning, the three of them left the market after breakfast, and in order to send jade sake to Ao Chuan, Bai Xuan and they deliberately went to the Lost Forest again.

As Bai Xuan guessed, as soon as the three of them entered the range near the Lost Forest, Ao Chuan appeared, Chen Hao explained his intention, and left sixteen jars of jade sake for Ao Chuan, and they themselves brought back two altars for the master as gifts, and they couldn't go back empty-handed when they came out, Master Jun Qing didn't lack anything, and he would not pick their gifts.

Ao Chuan didn't expect a few people to return so soon, and he was very happy with the words of the three little dolls, and when he saw that it was the best and most expensive jade sake in the market, he was even more happy, and opened a jar on the spot in front of several people and drank it bitterly.

Ao Chuan drank happily, naturally he would not let the three people who came to deliver the wine return empty-handed, and casually tore off the black shell-like thing hanging around his neck and threw it to Chen Hao, explaining, "This thing seals an incarnation outside my body, you can crush it when you encounter danger, and my doppelganger will appear to help you defend against the enemy, don't dare to say anything else, you can still resist for a while when you meet the junior of the Yuan Infant Period." ”

The three of them didn't expect that just a few jars of wine would be exchanged for such a precious gift, they were very surprised, and thanked them again and again, Chen Hao even took out the marinated meat skewers from the storage bag, and gave them to Ao Chuan together with the stove, and several people said goodbye to each other before turning around.

As for the storage of the incarnation shell (temporarily called the thing given by Ao Chuan as the incarnation shell), Chen Hao originally wanted to hand it over to Ye Sheng for safekeeping, first of all, she was the senior sister, and secondly, Ye Sheng was also the most assertive among the three. However, Ye Sheng and Bai Xuan unanimously decided that it would be more appropriate to put things in Chen Hao's place.

First of all, both of them understood very well that although Ao Chuan said that it was for the three of them, he took the initiative to throw this incarnation shell at Chen Hao, and the meaning of this was already obvious. Speaking of people, being able to make friends with Ao Chuan is almost always due to Chen Hao, and it can be regarded as a foolish person, and if you want to get true heart in this world, you naturally have to exchange your sincerity.

It was precisely because of Chen Hao's sincere heart without any impurities that he moved Ao Chuan that he would give them such a valuable thing after only two meetings.

Since Bai Xuan and Ye Sheng both felt the same way, Chen Hao only had a few obedient majorities and put this incarnation shell into his storage bag. His idea is also simple, the three of them eat and live almost all in one place, and it is the same for whoever they put there, whether it is a senior sister or a senior sister when needed, as long as it is an order, he will naturally do his best to do it.

The three of them returned to Feilai Peak under Ye Sheng's strong request in just three days, and the skirmish that occurred in the city made Ye Sheng discover that in addition to the equipment, they actually had many places where they were not fully prepared, and the Illusion Valley experience was about to begin, and they didn't have much time to delay.

So as soon as they returned to Feilai Peak, the three of them made new adjustments to the training plan after meeting Master Jun Qing. Ye Sheng borrowed Senior Brother Mo Tong, and the training mode changed from peaceful mutual feeding between the three of them to working together to subdue the enemy. Moreover, under Ye Sheng's strong request, several people went into battle with real knives and guns, and the training venue was also changed from Weimingju to a more spacious return to the forest.
