In this world, in order to keep a secret, killing people and destroying the whole family is normal. Yang Yan has seen Yang Kai's fierce murder. The warrior in the first level of the Holy King is not enough to see him. She knows very well that if Yang Kai really wants to attack her, with the weirdness of the demonic flame, no matter how many secret treasures there are on her, she may not be able to stop it.

At this moment, Yang Yan regretted knowing this huge secret.

Yang Kai glared at her: "What are you talking nonsense?"

Yang Yan immediately laughed: "I knew you were not like this. Just put away these ethereal crystals quickly. It would be bad if you let others see them."

Yang Kaishen agreed and quickly put the hundreds of ethereal crystals into the Mysterious Demon Book.

Until now, he was still a little dazed. If these ethereal crystals were really mined by the stone puppet in recent times, then there is only one possibility for the Longxue Mountain underground, because the stone puppet always runs underground.

But what Yang Kai couldn't understand was that he had clearly and carefully investigated the situation underground and had not found any ore veins. If there were really air stone ore veins here, the Haike family of Wuyi would not have known it. After all, this family has been rooted here for countless years.

It is necessary to figure this out.

Yang Kai reached out to pick up the stone puppet and rushed to Yangyan and said, "Come with me."

Yang Yan didn't ask much, as if he knew what Yang Kai wanted to do, and quickly followed him, with an expression of expectation on his pretty face.

After leaving the cave, the two of them quickly arrived at a valley more than ten miles away from the cave. They found a hidden location. Yang Kai put down the stone puppet and gave it an order to dig deeper.

The stone puppet soon disappeared, leaving only a small hole where one person could enter and exit.

In the past, when the stone puppet digged a hole, it only dug a small hole. But this time, in order to go underground to investigate, Yang Kai had to let it dig the hole a little bigger.

Yang Yan became even more excited, his face flushed, and stood beside him without saying a word, waiting to go down with Yang Kai.

Half an hour later, Yang Kai winked at Yang Yan and jumped into the deep pit in front of him.

I have to say that the cave dug out by the stone puppet is simply unique, with a cylindrical shape. The passage is extremely smooth, as if it had been polished with some tool. After Yang Kai jumped in, he did not encounter any obstacles at all. He slid down the road without any blockage.

The passage is very deep. It is hard to imagine that it took only half an hour to dig it out. Yang Kai deeply understood the skills of the stone puppet.

After sliding down for a stick of incense for a while, Yang Kai suddenly felt that the passage had reached its end, and the illusion of falling from a high altitude was vague. He quickly stabilized his body, and the next moment, his feet stepped on the ground.

There was a rapid cracking sound in his ears. Without looking, Yang Kai knew that it was the movement of the stone puppet gnawing on the ore. He took out a strange stone for lighting and held it up. Before he could see clearly the situation around him, Yang Yan's scream came from above his head: "Yang Kai help me, I... I'm stuck!"

Yang Kai looked up and his face turned dark.

Yang Yan was indeed stuck, and was stuck by a pair of huge weapons on his chest. His lower body was hanging above Yang Kai's head, and his legs kept kicking. However, his upper body was still in the passage and could not get down.

He reached out and grabbed her ankle, dragged her down hard, and pulled her down in Yang Yan's scream.

"It hurts so much!" As soon as Yang Yan fell, he covered his chest with both hands and kneaded it hard. He looked at Yang Kai with tears in his eyes, as if he was blaming him for being so ungrateful.

Before she could find trouble for Yang Kai, just by the light emitted by the lighting stone, seeing the surrounding situation clearly, Yang Yan was stunned, with his small mouth circle round, his delicate body trembling, and immediately forgot about the pain of the rubbing of his soft breasts.

Yang Kai seemed to have suffered some huge impact, and kept turning his head and looking around, and was so excited that he almost let out a long roar.

The two of them are now in an underground cave. This is probably a cave mined by the stone puppet in recent times. It is only about ten feet long and wide. However, under the light of the illumination stone, dizzying light is reflected on the surrounding cave walls.

Ethereal crystals, large or small, bright or dark, are embedded aside as if they are worthless. Among the ethereal crystals, there are empty stones with little value.

In the underground cave, there were only two people's heavy breathing and the crackling sounds of the stone puppet gnawing on the ore.

After a long time, Yang Yan suddenly screamed and rushed to the ethereal crystal that had not been mined at an incredible speed. He rushed up and leaned on it, with a satisfied expression on his face, and a cat-like murmur sound.

It cannot be said that Yang Yan is rare and strange. Yang Kai’s mood is not much worse than hers.

He never expected that there would be such a rich ethereal crystal mine thousands of feet underground in Longxie Mountain, which is a rare ore vein of the spirit herb, and there would be such a rich ethereal crystal mine!

Judging from the situation of this ore vein, this can no longer be called a Hollow stone ore vein, because the number of Ethereal Crystals accounts for almost half of it. It is fully qualified to be called an Ethereal Crystal ore, and it is no longer a companion creature of Hollow stone.

Yang Kai immediately understood why he hadn't even found out about the situation here.

First, the location here is very deep, Yang Kai did not check it too carefully, and second, there are too many ethereal crystals here.

This rare mineral is the main material used to make space rings. It has the function of blocking spiritual consciousness and detecting. If this is not the case, you can see something in other people's space rings by just scanning them.

The huge number of ethereal crystals isolate Yang Kai's divine consciousness investigation, and naturally hides it perfectly.

The secret that even Yang Kai's divine consciousness could not be detected, so naturally the people of the Heke family could not find it. It's ridiculous that they were the owners of this place, and they had no idea about it. Just because Wu Yi was a woman, they allocated this beautiful barren mountain to her as their territory.

If the stone puppet had not been born with sensitivity to rare ores, such a treasure would have been buried for countless years.

Yang Kai has never had contact with the Heke family, but because of Wuyi, he has no good feelings for this family.

This mountain was given to Yang Kai by Wu Yi. Now that she has found so much wealth here, Yang Kai really wants to thank Wu Yi.

But her strength is not high, she is not qualified or capable of occupying such a mineral vein. She occupies it, and it can only bring disaster to herself and the Heck family.

If you find an opportunity to compensate her in the future, Yang Kai made up his mind secretly.

"Yang Kai, we are rich!" Yang Yan rushed back at some point and stood in front of Yang Kai with a green light in his eyes, looking a little scary.

Yang Kai shook his head: "I'm the one who got rich."

Yang Yan pouted his mouth, pulled Yang Kai's arm and shook it, and said coquettishly: "Don't say that you are so arrogant, there are so many ethereal crystals, please share with me a little."

"What's the use of you want this? It can only refine a space ring. If too many space rings flow out from your hands, a fool will know that you have an ethereal crystal, and then it will only cause trouble for yourself."

"I don't refine the space ring. I need Ethereal Crystal to study a formation. I didn't have materials before, but now I have them. You can just divide me into a little bit. The formation I want to study is very powerful."

"What formation?" Yang Kai was shocked, as if he realized something.

"Have you heard of the space magic array?" Yang Yan did not hide it and said proudly, "It is the kind of magical formation that can teleport on a cultivation star. Well, you probably haven't heard of it like this, but you will know it's amazing when I research it."

"Do you understand the space magic array?" Yang Kai's eyes lit up and he looked at her with some disbelief: "How could you understand this? Didn't it mean that it had been lost long ago?"

Last time on Shuiyue Star, I used the space magic array of Hengluo Chamber of Commerce with the powerful demon clan Xue Tong. Xue Tong said that the current space magic arrays are all left over from ancient times. They only know how to use them, but they can't understand the principle.

A stunning and beautiful figure like the Ghost Ancestor spent nearly a thousand years studying the space magic array on the hanging continent. In the end, it was a mess, killing many people, and it was of no use at all.

So Yang Yan said that she understood the space magic array and surprised Yang Kai.

He had never asked Yang Yan about a question, that is, why she was not old, but she was already a virtual weapon refiner. Now she is just a middle-class alchemist at the Saint King level. Yang Yan is younger than him. No matter how outstanding her qualifications are, she cannot reach this level with her own efforts.

Now she said she understood the space magic array, which shocked Yang Kai even more.

Yang Yan stumbled for a few words, looking a little unwilling to answer.

"Forget it, there's no need to say it." Yang Kai didn't force her. Who doesn't have any secrets in his heart? The secret is that others can't know. Yang Kai has never liked to ask about other people's secrets.

"Then do you give it to me..." Yang Yan had a bitter face, afraid that Yang Kai would refuse, so he hurriedly said: "I tell you, if I study the space magic array, we can not only teleport on the Dark Star, but maybe we can also teleport on other cultivation stars."

"What?" Yang Kai was really shocked now.

"You don't want to be trapped in the dark star for the rest of your life, right?" Yang Yan looked at the words and quickly struck while the iron was hot. "There are many wonderful things outside that we have never seen. I heard that there are masters of the Void King Realm in the Star Domain, and there are many Void King-level materials. If you have those materials, I can refine Void King-level secret treasures. At that time, I will help you refine a secret treasure of this level. If you stand there as a target for others, you won't be hurt!"

The little girl actually knows how to lure her into profits!

But it is undeniable that Yang Kai was really moved.

He was moved not because of Yang Yan's unsecured promise, but because of the relatives and friends on Tongxuan Continent!
